Hi there!

Like I said earlier that I can't solve #1 so I will only solve #2 and #3
-----------------------------------------------------------------------------------------------

5^x = 7
First, we need to solve for the exponent x
log(5^x) = log(7)
x* (log(5)) = log(7)
x = log7/log(5)
x = 1.209062

---------------------------------------------------------------------------------------

Please let me know when you post the #3

Volume of a cylinder with a height of 8 and a width of 8

tangare [24]

Answer:

I am only in like 5th grade, but I'll do my best to answer this.

Step-by-step explanation:

Volume of a cylinder: πr^2h where "r" is the radius and "h" is the height

π * 4^2 because since the width is 8, half of that is the radius

π * 4^2 * 8 because you still have to multiply that by the height to find the full space inside

= π * 4^2 * 8

V ≈ 402.12 (rounded to two decimals)

Sue needs to drive 372 miles to visit her aunt. She stopped at a gas station one-third of the way in to her trip. How many miles

IRINA_888 [86]

Answer:

Sue has traveled 124 miles.

Step-by-step explanation:

Here, the distance covered by Sue is a fraction of the total distance to be covered.

The total distance to her aunt's = 372 miles

but the gas station is at one-third of the distance to be covered.

Thus,

Miles traveled by Sue = $\frac{1}{3}$ x 372

= 124

Miles traveled by Sue = 124 miles.

Therefore Sue has traveled 124 miles.
