Answer:
Melissa walked at a rate of 1.0 miles per hour.
Step-by-step explanation:
As given
Melissa walked at a rate of 88 feet per minute .
As
Now convert 88 feet per minutes into miles per hour.
Therefore the Melissa walked at a rate of 1.0 miles per hour.
10^2 = 100 and 5^2 = 25
100 and 25 gives you 125. Because, 100 +25 = 125.

Answer:
9) x = 32
11) x = 33.3
Step-by-step explanation:
9) 1/4x = 8
4 x 1/4x = 8 x 4
X = 32
11) 3/5x = 20
5 x 3/5x = 20 x 5
3x = 100
3x ÷ 3 = 100 ÷ 3
X = 33.33333
X = 33.3
Sn = −728
Sn = 2,186
Sn = 728
The sum of a geometric series is calculated using the relevant formula from a1, r, and an. The unknown n can be calculated from the given an, a1 and r. These are then substituted into the sum formula.
The given is a geometric series where first term a1 = -2, common ratio r = 3, and last term an = -1458. The sum of a geometric series, Sn, can be calculated using the formula , where n is the number of terms in the series. However, in this case, we don't know n directly, but we do know the nth term (an) using the formula , you can rearrange to solve for n: n = log((an/a1))/log(r) + 1. Plug this value of n and the given a1, r into the sum formula to get the sum.
