Answer:
300 in³
Step-by-step explanation:
To calculate the volume of a composite solid, simply split it into smaller solids and calculate their separate volumes. The volumes of each of the individual solids are then added together to give the total volume of the composite solid.
Remember, the formula for volume is: l • w • h
12(length) x 5 (width) = 60 x 3(height) = 180 in
5(width) x 8(length) = 40 x 3(height) = 120 in
Now, finally we add up the answers.
180 + 120 = 300 in³
(*Don't forget to cube³ your answer since it's Volume)
Answer:
the correct answer is option A. Length
So the equaiton is
number of nickes=n
number of quarters=q
if you have 1 quarter then you have 25 cents so we will represent like this
25q
and nickles is 5n
14.50=1450 cents
so
25q+5n=1480
q+n=88
subtract q from both sides
n=88-q
subsitute into first equation
25q+5(88-q)=1480
25q+440-5q=1480
add like terms
20q+440=1480
subtract 440 from both sides
20q=1040
divide both sdies by 20
q=52
there were 52 quarters
25(52)+5n=1480
1300+5n=1480
subtract 1300 from both sides
5n=180
divide both sides by 5
n=36
there were 36 nickels
nickles=36
quarters=52
It's 28 5/7. 10 +18 and 2/7 + 3/7
