Answer:
Option D
Step-by-step explanation:
The area of the trapezium is (6×5.2) + (3×5.2)=46.8cm²
Then times this by the depth
46.8 × 18 =842.4cm³
Option D
Answer:
x = 45
Step-by-step explanation:
0.36(18) + 0.04x = 0.12(24 + x)
6.48 + 0.04x = 2.88 + 0.12x
0.04x - 0.12x = 2.88 - 6.48
-0.08x = -3.6
0.08x = 3.6
x = 3.6/0.08
x = 45
Answer:
The width is 4 feet
Step-by-step explanation:
Yes, I might be able to answer it! Hello there!
In this question, we are asked to calculate the height of a pool which has a shape of right rectangular prism.
The key to solving this problem is simply by knowing the formula for the volume of a right rectangular prism.
Mathematically the volume V is w * h * l where w , h and l are the width, height and length respectively.
Now let’s input these values and get what the height of the pool is.
It would be easier if you had the measurements are in decimals;
137 1/2 becomes 137.5
6 1/4 becomes 6.25
5 1/2 becomes 5.5
kindly note the fraction 1/2 is 0.5 in decimals while the fraction 1/4 is 0.25 in decimals
So now let’s compute the height;
137.5 = w * 6.25 * 5.5
w = 137.5/(6.25 * 5.5)
w = 137.5/(34.375)
w = 4 feet
