Step-by-step explanation:
x + (x + 2) + (x + 4) + (x + 6) + (x + 8) = 135
5·x + 20 = 135
5·x = 115
x = 23
So the sequence is
23, 25, 27, 29, 31
The second number is 25.

Hi,The answer to your question is down belowThe width measures 10 feet.
Let the length be x and the width be <span>x−10</span>.
Since the pool is rectangular:
<span>A=L×W</span>
<span>200=x<span>(x−10)</span></span>
<span>200=<span>x2</span>−10x</span>
<span>0=<span>x2</span>−10x−200</span>
<span>0=<span>(x−20)</span><span>(x+10)</span></span>
<span>x=20and−10</span>
A negative answer is not possible, so the width of the pool is <span><span>(20−10)</span>=10</span> feet.

Step-by-step explanation:
The mean is given as 7. That is the only information given, and it is not enough to determine the number of raisin in each scoop.
Suppose the total number of raisins was given, then the total number of raisins is easily given as (total number of raisins) ÷ (mean)
= (total number of raisins) ÷ 7
Answer:
172 1/2 lb
Step-by-step explanation:
Determine the rate of change per month = lifts lifted in march - lift lifted in February
142 1/2 - 135 = 7 1/2
Determine the number of months from march to July = 4
increase in weight he would be able to carry in 4 months = 7.5 x 4 = 30 lb
weight he would be able to carry in april = 30 + 142 1/2 = 172 1/2
Pi * r^2 = 16.79
16.79/pi = 5.344.
r= 2.31
