a rain gutter is 24 feet long, 4 inches in height, 3 inches at base and 6 inches at top. how many gallons of water will it hold?

Lubov Fominskaja [6]

Answer:1.8701

Step-by-step explanation:

Area (A) of trapezium as marked is = $\frac{1}{2}$ $\left ( sum\ of\ parallel\ sides\right )\times height$

A= $\frac{1}{2}$ $\left ( 3+6\right )\times 4$

A=18 $in^2$

Now for Volume we have to multiply by length because area is same across the length.

volume(v)= $A\times length$

Volume(v)= $18\times 24$

Volume(v)=432 $in^3$

Volume(v)=1.8701 gallon

PIT_PIT [208]

Answer:

Candy is 21 years old

Step-by-step explanation:

If Alisa is 16 years old, that would mean that Barbara would be 8, since she is half of Alisa's age.

If we add 5 to Alisa's age, we get 21. To find the average of their ages, we add them all up, and divide by how many people there are (3).

16+8+21=45

45÷3=15

Hope this helps!
