Explain whether 20/16 is an equivalent ratio to 60/48

1 answer:

6 0

So since 20x3=60 all we have to do is multiply 16 by 3 to find out if it comes out to 48, which in this case it does, so the two ratios are equivalent.

A cylinder has radius 3 meters. Its volume is 141.3 cubic meters. Find its height to the nearest tenth

Misha Larkins [42]

Answer:

Height = 5meters

Step-by-step explanation:

Using the formula h= v over 3.14r^2 = 141.3 over 3.14 times 3^2 gives us 4.99747 meters.

Which of the following is a factor of 7x2 - 12x - 4? (6 points)

grin007 [14]

Answer:

We conclude that 'None of the above' is the correct answer.

Step-by-step explanation:

Given the expression

$7x^2\:-\:12x\:-\:4$

Breaking the expression into groups

$7x^2\:-\:12x\:-\:4=\left(7x^2+2x\right)+\left(-14x-4\right)$

Factor out $x$ from $7x^2\:+\:2x$

$=x\left(7x+2\right)$

Factor out -2 from $\left(-14x-4\right)$

$=-2\left(7x+2\right)$

so the expression becomes

$7x^2\:-\:12x\:-\:4=\left(7x^2+2x\right)+\left(-14x-4\right)$

$=x\left(7x+2\right)-2\left(7x+2\right)$

Factor out the common term $7x+2$

$=\left(7x+2\right)\left(x-2\right)$

Therefore, from the given options, we conclude that 'None of the above' is the correct answer.

GenaCL600 [577]

Answer:

(y+15) = 4/5(x+5)

Step-by-step explanation:

slope = (-7 - 9)/(-12 - 8) = -16/-20 = 4/5

(y+15) = 4/5(x+5)
