To @alyssa!
learn how to type math! Instead of this nonsense: 48−−√ Just type √48 It's much easier to read.

as soon as you determined that V = 2πr^3, you could just go on without having to find r. (2πr^3) / (4/3 πr^3) = 2/(4/3) = 3/2 and 3/2 * 60 m^3 = 90 m^3
you didn't really need most of that work. You had the dimensions of the tank, so you just needed Length (width) = 12 inches Height = 16 inches Depth = 35 inches diagonal is d = √(144+256+1225) = √1625 = 40.3
since you are given a side and an angle, the Pythagorean Theorem is of no use. Instead, if the other leg has length x, then tanθ = 12/x, so x = 12 cotθ
disagree You need to subtract 4x and add 12 and simplify
clearly, the user meant y = 3/4 x - 2 so, choices B.D are correct
still wrong. Unless the x-intercept is at (0,0), reflecting about the origin will produce a different intercept. The point (x,y) becomes (-x,-y) so (5/2,0) becomes (-5/2,0) which is the x-intercept of y=2x+5
still wrong, since there were: 8 unmarked red balls so we have 8 neutrons 6 protons 6 electrons
the user clearly stated: 6 blue balls marked with plus signs so these are the 6 protons, not 8
that has to be some of the worst user typing I have ever seen!
that's because the user doesn't know how to type math. It was supposed to be √−60 = 2i√15
what a lot of useless work! 10 < a/b < 11 10b < a < 11b so pick any whole number for a. Let's say 6. Then 10b < 6 < 11b so b < 0.6 and 0.54 < b so we can use b = 0.57 That gives a/b = 6/0.57 = 10.52 which is ok, since 10 < 10.52 < 11
since 20 was included twice in the options, I'd say there was a typo, and the correct choice of -20 was just mistyped.
still wrong. the solution set of 5x - 5 = 10 AND 5x + 4 > 14 is x=3 AND x>2 that is, only x=3.
since the equation has a single solution, which is also a solution of the inequality, the solution set of the two equations is only x=3.
wrong. A factor of 10 guarantees a 0 in the 1's place
i believe there is a typo, since "cousin" in Spanish is "primo" not "promo"
wrong -- 90°
clearly, the user meant 9 + 27/(2x) = −3/(2y) this simplifies to 9/x + 1/y + 6 = 0 which is a hyperbola, and has no x- or y-intercepts so the question was poorly posed.
wrong. The square root of 81 is 9. Period. Just because both 9 and -9 satisfy the equation x^2 = 81 does not change the fact that the square root of 81 is 9.
did you check your answer? 8x^4 - 32x^3 - 5x^2 + 20x = x(x-4)(8x^2-5) and if you're not requiring rational coefficients, then 8x^4 - 32x^3 - 5x^2 + 20x = x(x-4)(√8 x-√5)(√8 x+√5)
I think it's clear that the capital Y is supposed to be the same as the lower-case y. So the answer is y^56
right you are. I didn't watch the signs. x/6 + y/-3 = 1 gives the correct intercepts.
or, just use the intercept form. Divide by 12 to get 2x-4y=12 x/6 - y/3 = 1 So the intercepts are (6,0) and (0,3)
Seems to me the user meant Mistakes were made. We will do all we can to correct them.
By this time, you should have learned the common ways users mistype fractions. As it was worded, the question is very silly. It is clear the user meant Find a rational number between 2 and 2 1/4 so using your method, the answer is (2 + 2 1/4)/2 = 2 1/8
why do users not know any more how to type roots and fractions? x^(1/6) * x^(1/6) = x^(1/3)
work W = Fx, not 1/2 Fx so W = 15N * .04m = 0.6 J
After the concert, Kimi asked her mother to come and pick her up. The direct object is the noun phrase "to come and pick her up" "mother" is an indirect object.
nope. In QIV, cot is negative. So cot 300° = -1/√3
given the choices, clearly the user meant (4x^2+7x-3) + (2x^2+7x-5)
as written, the question makes no sense. It should be clear that they meant 3/16 = 0.1875
or, since F = kx, just solve 40/2 = x/2.5 x = 50
actually, I made a mistake which you missed. since 9/4 < √7 the only correct choice is 2.666..., √7
once again, obscure user notation makes the problem unreadable. But by now you should have learned to figure this out. The real problem reads: Which of the following options includes a rational number and an irrational number between √6 and √8 ?(1
√24 = ∜24² = ∜576
two different answers, both involving roots, but how does 9 1/3 involve roots anyway?
I'm pretty sure that the user meant 6×√2 = 6x1.4 = 8.4 so, D
to make it even easier, consider that √9 = 3. so just subtract 1/7 from that, giving 2 6/7 = 20/7
I think the user meant 3 8/9 = 3.8888...
or, since sqrt(x) is monotone increasing, 48 > 36, so √48 > √36
clearly, the user meant 6–√ to indicate √6, which is irrational

MOMENTAE seems wrong, because it does not match the pattern. Try MOTIVATE
stupid git -- you generated the exact same sh**t as before
you know, since you go to the trouble of verifying that we are human, maybe you should present text that is easy for humans to read. So, instead of \[ V = \frac{4}{3} \times 3.14 \times (3)^3 \] generate 4/3 * 3.14 * 3^3
wrong again. Can you not do basic algebra? x/(x²-1) * (x²+4x+3)/(x²+3x) x/((x+1)(x-1)) * [(x+3)(x+1)]/(x(x+3)) The x, x+1 and x+3 factors cancel, leaving 1/(x-1)
no, B has slope 6 You want D: y = -1/5 x + 6 By now you should have learned that many users can't type fractions.
boy, did you get lost on this one! 9x/(2(x+1)) - x/(x+1) = (9x - 2x)/(2(x+1)) = 7x/(2(x+1))
if the scale factor is 1:4, then the volumes are in the ratio 1:4^3 = 1:64 so, the answer is A:37.5
