Hello. This a simple d = rt problem. Distance (70 m) = 40 miles * hour. Thus, it would take 70/40 hours to travel 70 miles at the constant speed of 40 miles per hour. (I don't know why the driven about 30 m was stuck in)

35/100 * 20 = 35/5 = ?

THANKS ALOT STEVE THANKS ALOT I REALLY APPRECIATE IT!!

1.07 * 22 = tom's price 1.04 * 18 = his cousin's price then to see who spent more on tax, 0.07*22 = how much tom spent on tax 0.04*18 = how much cousin spent on tax

We could go see by the logical way.... tom's tax is 7% cousin's tax is 4% tom's price is higher than cousin's... hmm... who has more tax?

for 2nd equation, we get x = 2y-3 thus plugging into first equation gets (2y-3)^2+9y^2 = 37. 4y^2-12y+9+9y^2 = 13y^2-12y+9=37 = 13y^2-12y-28 = 0. Solving with the quadratic formula gives us: 2,-14/13

let t = team wins let r = team remains in playoffs let c be championship within reach let } = If x then y (The if, then part) let :; = therefore Thus, t } r r } c :;t } c This is a pure hypothetical statement. FYI in the argument t } r, t is the antecedent and r is the consequent. thus the argument is valid.

ok thanks alot steve you really help alot

this is a mixed hypothetical statement. there are 4 forms, 2 are valid 2 are not. let the antecedent of the first statement be t, and consequent be e. ~p = not p thus we get t } e ~e :; ~t This is modus tollens literally the way that denies by denying, which is a valid argument.

x *x+2 = 82, x^2 +2x = 82. use the quadratic formula to find the answer

solve for x and y in each equation a 7x=3, x=3/7 no b y=12, no c 7x+5 = 7x+5 => 5=5 YES d 6y-2 = 2y-2 => 4y=0 y=0 no

So wouldn't it be a noun...?

the stuff on one side has to equal the other side : x =x infinite solutions 5=5 infinite solutions etc

c should be the right answer....

1/4 of all cards are clubs. use probability.

its probably C

for 1 (4x-3)(x-2) for 2 (3x-3)(3x-7)

64z^2 - 1 => (8z-1)(8z+1)

for number 2, (7g-3)(5g+3)

How long does it stay in the air? The problem needs more information or else it is unsolvable.

ok, so its kinda like multiplying fractions except u flip the second one upside down(reciprocal): so 1/2 divided by 2 = 1/2 divided by the reciprocal of 2 which is 1/2 so 1/2 * 1/2 = 1/4 thus, in this case, it would be 7/9 divided by reciprocal of 3/6 = 6/3 so 7/9* 6/3 = 7/9 * 2 = 14/9 : 1 5/9

went in forest: 1/4 x in mountain: 2\sqrtx x - 1/4x - 2\sqrtx = 15 3/4 x - 2sqrtx = 15 square both sides 9/16x^2 - 4x = 225 divide both sides by 9/16 x^2-64/9x = 400 x^2 - 64/9x -400= 0 use factoring

or u could guess seeing that a camel cannot be split into quarters or sqrts. thus it must be a number less than 100 which is a square and divisble by 4...so the answer is 36

second die : 2,3,5 to get 7, must be 5,4,2 probability = likely outcomes / all outcomes i think it is 1/2 - don't trust me not a reliable source

xy = 2004 x =21y 21y * y = 2004 21y^2 =2004 y^2 = 2004/21 y=sqrt 2004/21 plug in to get x

no offense but it is kind of hard to solve a problem to find a length when given no lengths...did you copy/paste wrong? Anyway, first when there is an angle bisection always use angle bisector theorem. also, the orthocenter is where the altitudes meet

thanks a lot the answer is 18 right? merry christmas and happy new year to y

awesome...just kidding. Amateur singing, dancing, theater. Horse races, playing games such as chess, etc. happy new year

I meant the total number of possibilities. Thanks anyway!

Question: Is this math?

he lost 4% and lost 22 dollars 1. 1.2 x 2. 0.8 * 1.2 x = 0.96 3. 0.96*550 = 528 4. 550-528 = 22

yes I believe it is c as well

Conceptual frameworks (theoretical frameworks) are a type of intermediate theory that attempt to connect to all aspects of inquiry (e.g., problem definition, purpose, literature review, methodology, data collection and analysis). Conceptual frameworks can act like maps that give coherence to empirical inquiry. Because conceptual frameworks are potentially so close to empirical inquiry, they take different forms depending upon the research question or problem.

so sqrt { x+7} = 1 right? if so... then square both sides to get x+7 =1 x = -6

circumference = diameter * pi thus 204 cm = diameter (x) * 3.14159265358... or about 3.14. use division: 204/ 3.14 = ?

thanks a lot guys for your interest. Yes, it is somewhat of a confusing problem. @Steve: I appreciated it a lot and you did a very good job at explaining it. Thanks a lot guys and Happy New year. take care!

It would be great if you could somehow edit the function / math part of the problem because I do not understand if you are talking about "if less than or equal to -5" or "x<1" or "if -5 less than or equal to x<1" Thanks a lot and Happy New Year

uh you mean pattern? well the 2nd is 3/4 of 48 and the 3rd is 3/4 of the 2nd. it is a geometric series with ratio 3/4 and first term a

16 = 2 x ? ? = 8 8 = 2 x ? ? = 4 4 = 2 x ? ? = 2 2 x 2 x 2 x 2 x 3 = 48 Happy New Year Man

Hi. I am assuming . = x or * or times so then it would be 2 +30 since multiplication goes before addition. (order of operations) then 30+2 = 32. multiplication and division go first so 32/5 * 3 = 64/5 -9 = 64/5 - 45/5 = 19/5 = 3 3/5

ok plug it in. for example... x + 1 = ? if x = 1 thus 1 replaces x, (get rid of the x and stick in a 1) so we would get 1+1 = 2 same here. remove the a and stick in a 33 to get 33-13 = ?

Without going into log, first remember: x^(1/2) = sqrt x. (I am assuming you are not talking about (16^1)/2 which is 8). For example, if 4^2 = 16, what is 4^(1/2)? IT would be a number squared to be 4. So its 2. Same thing. what is sqrt x? remember a number squared = the number times itself. so what squared = 16? it is 4

Hi. First thing you ever want to do when seeing these kind of problems: Break it into pieces, otherwise known as get rid of most of the words. For the first PARAGRAPH, all you need to know there are 400 tenants each pays 2k a month. thus in a month u get 400 * 2k = 800000 or 800k. chop down the rest

Hi, first thing you do is to want to find Formulas formulas formulas. hey, this is a arithmetic sequence! An arithmetic sequence is A series such as 3 + 7 + 11 + 15 + ··· + 99 or 10 + 20 + 30 + ··· + 1000 which has a constant difference between terms. The first term is a1, the common difference is d, and the number of terms is n. The sum of an arithmetic series is found by multiplying the number of terms times the average of the first and last terms. The sum of an arithmetic sequence is a_1+a_n/2 *n All you need to know is that the sum is the first term plus the last term divided by 2 times the number of terms is the sum. so...1+100 = 101. 101/2 * number of terms is the answer. one more thing...the way to find how many numbers in a sequence which goes up by increments of 1 is minus the first from last and +1. thus we have 100-1 = 99. 99+1= 100 so 101 /2 * 100 = 50 * 101 = 5050

Compound interest P is the principal (the initial amount you borrow or deposit) r is the annual rate of interest (percentage) n is the number of years the amount is deposited or borrowed for. A is the amount of money accumulated after n years, including interest. When the interest is compounded once a year: A = P(1 + r)^n Simple Interest A = (r/100 * P )n

Oh sorry Ms. Sue is right...

Physics - Damon, Saturday, November 17, 2012 at 8:28pm T sin 30 = force up = 730 T = 1460 N in cable A T cos 30 = horizontal component = 1460 cos 30 = 1264 N I did not post this...Damon did This problem is the same thing but with a sign weighing 730 N

14/6 = 7/3 :D

and fyi 2i is an imaginary number...

Thank you so much guys I really appreciate it!!!

x+x+5+x+10+x+15+x+20 = 425 5x+50=425 x=75 x+20 = 95 answer = 95

miles truck drove before car left rest stop = 45 * 1/4 miles an hour at which the car is catching up : 60-45 = 15 mph how long to drive 45/4 miles at 15 mph?

/i got 300-34 pi

Thanks a lot steve it really helps!

If it is not economically discouraging, or is otherwise plagiarizing another person's work, I don't see why not. Even if it isn't a good idea, you will still learn something out of it.

B always positive for example, this would be positive number - negative number = positive number + - - positive number = positive number 3 (positive number ) - (-14) (negative number) = 3 --14 = 3+14 = 17. btw it cant be 0 because the first number is positive

find the least common multiple 8, 16, 24 12,24 so every 24 minutes 9:00 am + 24 minutes = 9:24am

to get sum of 1 = 0. to get sum of 2 = 1/36 since there are 6 options on each die and two die so 6*6 = 36. And the only way to get two is 1+1 to get sum of 3 = 1+2, 2+1, so 1/18 to get 4 = 1,3 2,2 3,1 so 1/12 to get 5 = 2,3 3,2 1,4 4,1 so 1/9 etc etc etc so after writing them all down, we find that 5 and 9 are equal: to get 5 = 2,3 3,2 1,4 4,1 so 1/9 to get 9 = 3,6 6,3 4,5 5,4 so 1/9 no other ones because the die only has 6 numbers. so the answer is B

thanks a lot i appreciate your time

to get the x intercepts and y intercepts ( or as you call it two points of intersection), set one variable to 0 and solve for the other. then set the other variable to 0 and sovle for the first. so let x be 0 first. 5*0 -2y = 10 so -2y = 10, so y= -5. We write this as (0,-5) since x goes first and y last. doing this for the second scenario, we set y = 0. so, 5x - 2*0 = 10 5x= 10 x=2. Thus, since x goes first, we find (2,0) therefore, we get (2,0) and (0,-5) and which answer is that may i ask? it is B.

just saying angie, you don't need to post twice, but alls good.

uh, what was the first option? but anyway ninety hundreths is equal to 90/100 or written as 0.90 it is also said as "nine-tenths" since you can simplify, so it would be 9/10, and 0.9 otherwise. but anyway they are all the same.

first simplify to lowest terms, so the frist fraction is 4 3/5. then we find least common denominator, so least common multiple of 5 and 4 is 20. we times first fraction by 4 and second by 5. thus we get 4 12/20 and 3 15/20 then we convert to improper fraction to get 4*20 + 12= 92 92/20 - 3 15/20 the second fraction is 3*20 + 15 = 75 so 92/20 - 75/20 so 92-75 = 17 so it is 17/20

convert to common denominator and compare

first it is a dependent clause, since it cannot stand by itself. it is also a relative clause, since Relative clauses are dependent clauses introduced by a Relative Pronoun (that, which, whichever, who, whoever, whom, whomever, whose, and of which). it is also restrictive, as A nonrestrictive clause is not essential to the meaning of the sentence; it can be removed from the sentence without changing its basic meaning. If you need further help, type in "clauses" into google search and click on the first search you see.

true. also, u can reduce each fraction to find common denominator faster and less messily

wat...? could you further explain, im confuzzled.

could you set the equation down, thanks

is it compound interest?

further explanation needed please

go to thesaraus

yes it is correct, since it is 2 sentences joined with a conjunction, thus pinning the name of the sentence a "compound sentence".

np. anyways, This is a pretty easy question to answer. The three possible (winning) outcomes are: 1. Heads, Heads, Tails. 2. Heads, Tails, Heads. 3. Tails, Heads, Heads. If we look at the possible combination of other (losing) outcomes, we can easily determine the probability: 4. Heads, Heads, Heads. 5. Tails, Tails, Heads. 6. Tails, Heads, Tails. 7. Heads, Tails, Tails. 8. Tails, Tails, Tails. This means that to throw heads twice in 3 flips, we have a 3 in 8 chance. This is because there are 3 winning possibilities out of a total of 8 winning and losing possibilities. Good luck

if he spent 26% x on skis which is equal to 350 we set equations 26/100 x = 350 so 13/50 x = 350 so multiplying both sides by 50/13 gives us 50/13 * 13/50 x = 350 * 50/13 x = 350*50 /13 which is equal to around 1346, or 1346.15385 to be exact

16200 / 14500 = ? we simplify by crossing out 0s 162 / 145 so nearly 12 % or...11.724137931% to be exact

sorry forgot to add, minus minus one from 162/145

It is very good, detailed and professional. What is the title of report? thanks

1.5 * 5 = ? 1.5 * 7 = ? 1.5 * 5 *2 + 1.5 * 7 *2 - 24 = ? fyi it equals 15 + 21 - 24 so 36 - 24 = (12)

65 ....

50, 20, 10 = 80 50, 20, 100 = 170 50, 10, 100 = 160 20, 10, 100 = 130 so 4 sums, correct me if i am wrong

look for combos or just add 2+8 + 20 + 5 + 11+14 +17 = 10+25+25 + 17 = 60 + 17 = 77

1,1,1,7 1,1,2,6 1,1, 3, 5 1,1, 4, 4 etc.

Thank you very much it helps a lot!!

atural defence mechanisms (or innate factors) against malaria are most apparent in populations continually exposed to malaria parasites. For example, inherited conditions such as sickle cell anaemia and beta-thalassaemia, which cause deformities in red blood cells and are common in people from malarious regions, make it more difficult for malaria parasites to infect red blood cells. Some people have red blood cells that lack proteins called Duffy antigens on their surface. These proteins act as receptors for Plasmodium vivax merozoites, so people without Duffy antigens are resistant to infection from this parasite.

ok thanks

I could also i think find the area of the square/rectangle and minus the pieces that are not part of the triangle

Cross multiplying gives us PV = RT. Then, we divide both sides by R to give us T= PV/R

sorry, i cant read it....6-1x0?? anyway if you meant 6-1x * 0 + 2/2 = 6-0 +1 = 7 or if you meant 6-1x + 2/2 we get 6-1x+1 = 7-1x

Uh....I can't read it...

Sales of whiskey will fall by 4%. Finding the solution to this problem is simple algebra. The equation for the price elasticity of demand is Elasticity=%Change Quantity Demanded / %Change Price Therefore, we just plug in the figures we are given and solve for % Change Quantity Demanded -.2 = X / .2 Multiple -.2 by .2 and we get -.04 which is 4% which is the % Change in Quantity Demanded

thank you very much it helps a lot!!!

thanks a bunch sire

To expound on Ms. Sue's comment, principally the "sentence" : Which meant they won more battles. So, you could combine this sentence with the previous sentence by replacing the period with a comma.

A diagram would be nice. assuming DE ~ AB let the sides of DEF be d,e,f. let the sides of ABC be a,b,c. a/b = d/e a/c = d/f etc. When we are given lengths, plug them in

Similar triangles have similar ratios DE / AB = 6/4 = 3/2 EF/BC = 9/6 = 3/2 So we know that DF / AC = 3/2 We are given that AC = 5 So, DF / 5 = 3/2 We cross multiply to get 15 = DF x 2 So, DF = 15/2 And, to the nearest tenth it is equal to 7.5
