Okay, since quotient is the answer to a division problem, you will divide w and -8. Increased means to add so, you will +7.

w/-8 +7 is what the expression looks like.

Minus a from both sides
x-a=-2by²
times both sides by -1
a-x=2by²
divide both sides by 2b
$\frac{a-x}{2b}=y^2$
sqrt both sides
$y= \sqrt{\frac{a-x}{2b}}$

Ne4ueva [31]

Answer:

premium: 165 gallons
water: 120 gallons

Step-by-step explanation:

Let 'a' represent the amount of 95% antifreeze in the mix. Then the amount of water is (285 -a). The mix has this amount of antifreeze in it:

0.95a +0(285 -a) = 0.55(285)

a = 0.55/0.95(285) = 165 . . . gallons of 95%

285 -a = 285 -165 = 120 . . . . gallons of water

There are 120 gallons of water and 165 gallons of premium antifreeze in the mixture.

Answer:

$V=90$

Step-by-step explanation:

<u>Step 1: Find the volume of the cone</u>

<u /> $V = \frac{\pi *r^{2}*h}{3}$

<u>Plug in the values</u>

<u /> $V = \frac{\pi *3^{2}*10}{3}$

<u>Simplify and Solve</u>

<u /> $V = \frac{\pi *9*10}{3}$

$V = \frac{90\pi }{3}$

$V = \frac{90*3 }{3}$

$V=90$

Answer: $V=90$
