Answer: Answer:
length= 53.22
width= 17.74
Step-by-step explanation:
Assuming the tank is a rectangular prism, then the formula for its volume will be:
volume= height* length * width
v= h * l * w
The length is equal to 3 times width, to put into the equation it will be:
l= 3w
We know that volume is 315 cubic feet and height is 3 feet, if you substitute all value into the equation we can find out the width.
v= h * l * w
315= 3 * l * w
945 = 3w * w
3w^2 = 945
w^2= 315
w= 17.74
Then we can find out length
l= 3 * w
l= 3* 17.74= 53.22

Answer:
18.18%
Step-by-step explanation:
-Percent error is defined as the deviation as a percentage of the actual value.
#Given the actual sold units is 110 and the predicted is 90, the percent error can be calculated as:
Hence, the perecent error is 18.18%
Answer:
Solve the equation. 2x – 3 = 15
x = 6
x = 9
x = 24
x = 36
(fg)(x) = (3x + 6) (<span>2x^2)
</span>(fg)(x) = 6x^3 + 12x^2

The angle fact that is necessary to prove that m∠1 + m∠2 = m∠2 + m∠3 is: linear pair are supplementary.
<h3>Linear Pair/Angles on a Straight Line</h3>
- Two angles on a straight line can be referred to as a linear pair.
- The sum of the angles of a linear pair equals 180 degrees (supplementary angles)
Thus,
∠1 and ∠2 are on a straight line, therefore,
m∠1 + m∠2 = 180°
∠2 and ∠3 are on a straight line, therefore,
m∠2 + m∠3 = 180°
Thus:
m∠1 + m∠2 = m∠2 + m∠3
Therefore, the angle fact that is necessary to prove that m∠1 + m∠2 = m∠2 + m∠3 is: linear pair are supplementary.
