Answer:
131.88m^3
Step-by-step explanation:
take 42 and multiply it by pi which should be 3.14 which equals 131.88m^3
Answer:
2
Step-by-step explanation:
because when x, the input, is -3, the y, the output, is 3
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:
70 ft
Step-by-step explanation:
You want the actual width of a gym that is represented as 7 inches on a drawing with a scale of 1 in : 10 ft.
<h3>Scale factor</h3>
Each inch represents 10 feet, so 7 inches will represent ...
7 × 10 ft = 70 ft
The gym is 70 ft wide.
__
<em>Additional comment</em>
You can also write and solve an equation that shows the measures are proportional:
actual width / drawing width = (10 ft) / (1 in) = (gym width) / (7 in)
Multiplying both sides of this proportion by 7 in, we have ...
gym width = (7 in) × (10 ft)/(1 in) = 7 × 10 ft = 70 ft
Answer:
D
Step-by-step explanation:
1. Make it into a y = x equation
y = 9x +7
2. change x to y and y to x
x = 9y + 7
3. Isolate y ( if not possible, use implicit differentiation but here you can)
x-7 = 9y
1/9x-7/9 = y
