1) The greatest amount of rainfall is? times as great as the least amount of rainfall<br>

leonid [27]

The image graph for this question is missing, so i have attached it.

Answer:

The greatest amount of Rainfall is 16 times the least amount of Rainfall.

Step-by-step explanation:

From the image, we can see the average monthly Rainfall and the frequency of each size in inches.

The largest is 2 inches while the smallest is ⅛ inches.

We are basically required to find the number that will be multiplied by the least amount of Rainfall to get the greatest amount.

Thus, we will just divide the greatest amount of Rainfall be the least.

This is; 2 ÷ ⅛ = 16

Why would I google to find a calculator for this TELL ME ASAP

Svet_ta [14]

The perimeter of a rectangle is 2(l+w).
The width is 1 so: 2(l+1)=10.
2l+2=10 ---> subtract 2 from both sides.
2l=8. -->Divide by 2 to isolate l.
L=4
Check:2(4+1)=10.
2*4=8
2*1=2
8+2=10
Length or V= 4

Hope this helps!
