Answer:
300 cm^2
Step-by-step explanation:
The volume of the rectangular prism is calculated by multplying lenght to the widht to the height
20*15*10 = 300 cm^2
Area of a triangle = 1/2 x base x height.
Replace are and base to get:
82.5 = 1/2 x 15 x height
Multiply both sides by 2:
165 = 15 x height
Divide both sides by 15:
Height = 165 / 15
Height = 11 inches.
Answer:
<h2>Table 2 is correct, you have it wrong</h2>
Step-by-step explanation:
The way we determine if ratios are equivalent is by a proportion. It also helps to know that a foot is 12 inches, so you have the wrong answer. The correct answer is table 2. The way we solve is by dividing the number of inches by 12 to see if we get the number of feet specified on the table.
24/12 = 2
60/12 = 5
72/12 = 6
84/12 = 7
All of these match up to their respective foot measurements.
Solve your equation step-by-step.
2(x−3)−17=13−3(x+2)
Simplify both sides of the equation.
2(x−3)−17=13−3(x+2)
Simplify
2x−23=−3x+7
Add 3x to both sides.
2x−23+3x=−3x+7+3x
5x−23=7
Add 23 to both sides.
5x−23+23=7+23
5x=30
Divide both sides by 5.
5x/5 = 30/5
x=6
The easiest way to solve this problem is to just move the decimal point to the right one place.
1.25 → 12.5
Your answer should be 12.5
