85(7)+85x=1955 1955-85(7)= 85x then divide both sides by 85 to get the months until you reach 1955
Not much to it. Hit the log function on your calculator then type in .72
B and C
Yes Pizarro conquered the Inca
Is the exchange rate 1 dollar = .0529 peso? If so, multiply the amount u found in dollars by .0529
Best guess is option 2. But it could either one with ethos
You would graph the line with the found slope and plot it through the points and see where it crosses the axis. Better yet use a point ex) 5=(2/5)5 + b Following the form of y=mx+b
For the height of the stack, multiply the thickness of a bill by the National debt(ND). Don’t know what the largest denom. In circ today is. For how much area in a single layer, find area of a dollar bill and multiply by the ND. Then compare to the area
Convert both to fractions with a common denominator of 21 and subtract. (14/21)-(9/21)
41.4/12 gives the amount in a pitcher. Multiply it by seven
Yes I believe so
So to multiply this out (x-5)(-.025x +220) X*-.025x, x*220, 5*-.025x, -5*220 -.025x^2 + 219.875x -1100 I am pretty sure the middle term should be 221.125x because you can’t decide when to/not include the negative sign before the five.
Change them to improper fractions with a common denominator multiply and then the answer should be positive
yes
add 7 to both sides and divide by 9. x=0
A and C are a part of the method. Hypothesis is what you want to test.
A control group is a group which does not receive the treatment which in this case is the fertilizer. So A would be the best choice
Repeating decimals are numbers that are never-ending. For example 1/3 is a repeating decimal because it is .333333333 and keeps going. on the other hand 1/2 is not a repeating decimal because it is a clean number 0.5. For part B, we know 20/20 = 1 so we
make a scatter plot of leg press reps vs 40 yd dash time. line of best fit would be what goes through or close to most points. You have the table so try using either a graphing calculator or a program for finding the line of best fit. Try Desmos or
You would most likely want answer B. But more than one trial would be ideal to get conclusive data.
Find the common factor between the two denominators, convert fractions into fractions with new denominator, perform (14/21)-(9/21) = 5/21
I would add the word “excessively” to your definition. Think of being pompous as being arrogant or conceited
The proportion would be 2.5L ( 1 gal/3.78 L) use a simple unit conversion
Use the balanced equation to convert 24g of glucose to mol of glucose then to mol of CO2. Then use the PV=nRT equation to solve for volume. Ps I might be wrong
24 total pieces. 5 people total. 24=5x x=4.8 round down to 4 because you would be over 24 if rounded up so yes 4 pieces left
If you are asking the total distance traveled, add 4.99+2.4.
Prime numbers are numbers which factors are 1 and itself. For example the factors of 3 are 1,3. For 5 they are 1,5. For 7 they are 1,7. The other three numbers given are composite numbers which have more than 2 factors. ex) 6= 1,2,3,6 10=1,2,5,10
To factor two terms, you must see what values they share. In this case both 2k and 10 have 2 as a factor. So to factor do this 2(k+5). Notice how this is the same as the expression above just not distributed out

Assuming you mean 9/10 and 7/20, convert 9/10 to an equal fraction with a denominator of 20 and subtract
For conditional probability, the key phrase in the statement is the term “such that”
I believe that NaF is an ionic compound
(8/45) = (4/9)x Solve for x. Probably be easier to put fractions into decimals
It is Geographic Information Systems and what video were u referring to
Cond. probability statements are stated as this: find this such that it is this. th e part after such that is the condituion
subtract 29 from both sides. divide each side by 6 6x + 29 =5 6x=-24 -24/6 = x = -4
D=sqrt((y2 - y1)^2 + (x2 -x1)^2) D=sqrt( 9 + 16) D=5
841 would be c^2. You must square root to get c.
No incorrect. Use a^2 + b^2 = c^2. C is the length of the hypotenuse. So solve for a or b. Plug in 9 as a or b and 12 as c then solve for the unknown
No incorrect. Use the formula a^2 + b^2 = c^2. Solve for c
X + (x-22) = 102
I believe it is #1
Your answer is? tip: get y by itself on the left side
google it
The fractions are weird because it goes from having a 4 space Punnett square to 16 because of the inclusion of a second trait in the genotype. The majority has both dominant alleles, 3/16 has only one dominant allele. 1/16 is both recessive alleles no
I am not familiar with the term penetrance. But to find part a, perform a cross between two Hh individuals and it should come out to like 75% like shiny objects.
Exponential decay
(26/52)+(25/51)
1 story is about 10 feet. Convert that to meters. Find total distance. Divide total distance to travel by velocity for time
Subtract 4 from both sides
