The cube root of (n increased by 8), or  ∛(n+8), is -0.5, or -1/2.

∛(n+8) = -1/2.  To solve this for n, cube both sides, obtaining n+8 = -1/8.

Eliminate the fraction by mult. all three terms by 8:             8n + 64 = -1

Solving for n:  8n = -65, so that n = -65/8.

jenny drove 210 miles using 9 gallons of gas. at this rate, how many gallons of gas would she need to drive 413 miles? gallons
Nina [5.8K]

17.7 gallons of gas would she require to travel 413 miles at this rate when Jenny used 9 gallons of gas to travel 210 miles.

Given that,

Jenny used 9 gallons of gas to travel 210 miles.

We have to find how many gallons of gas would she require to travel 413 miles at this rate.

We know that,

Jenny used 9 gallons of gas to travel 210 miles.

Then

Rate = 210 miles/9 gallons

= 23.3 miles/gallon.

So,

Nicole can achieve a fuel efficiency of 23.3 miles per gallon.

He has a 413-mile drive ahead of him.

So,

413/23.3 = 17.7 gallons needed.

Therefore, 17.7 gallons of gas would she require to travel 413 miles at this rate when Jenny used 9 gallons of gas to travel 210 miles.
