Answer:
2. c) 1050 mm³
3. c) 8 yards.
Step-by-step explanation:
Given the following data;
Length = 25mm
Width = 7 mm
Height = 6 mm
To find the volume of the rectangular prism;
Volume of rectangular prism = base area * height
First of all, we would determine the base area;
Base area = length * width
Base area = 25 * 7
Base area = 175 mm²
Next, we find the volume;
Volume of rectangular prism = 175 * 6
Volume of rectangular prism = 1050 mm³
Question 2.
Given the following data;
Length = 9 yards
Width = 7.5 yards
Volume = 540 cubic yards
To find the height of the rectangular prism, x;
Volume of rectangular prism = length * width * height
540 = 9 * 7.5 * x
540 = 67.5x
x = 540/67.5
Height, x = 8 yards
Answer:
12cm
Step-by-step explanation:
1. Define the variable:
x = length of the rectangle
2x = width of the rectangle
2. Set the equation:
x + 2x is half of the rectangle
2(x + 2x) is the perimeter
So,
2(x + 2x) = 36
2x + 4x = 36
6x = 36
x = 6
Since x is the length, multiply it by 2 to find the width.
2x = 12
Answer:
x= 2,-2
Step-by-step explanation:
Answer:
x = 7
Step-by-step explanation:
2x + 1 = -3x + 36
2x + 3x + 1 = -3x + 3x +36
5x + 1 = 36
5x + 1 - 1 = 36 - 1
5x = 35
5x/5 = 35/5
x = 7
