You would do 10x10x10x10x10, so it would be 100,000. So you're correct, nice job!
Rectangular prism is nothing but cuboid.
Volume of a cuboid = length × breadth × height
Base area = length × breadth
It is given that base area = 24 square feet and
height = 5.25 feet
Now, volume = length × breadth × height
= base area × height
= 24 × 5.25
= 126 cubic feet
Hence, the volume of the rectangular prism is 126 cubic feet.
Answer:
The situation best for the equation 3x=288 Is by dividing both sides by the coefficient of x to single out the variable
Step-by-step explanation:
=> 3x/3=288/3
=> x = 96
Answer: 30 pounds of coffee beans worth $10.50 per pound was used.
20 pounds of coffee beans worth $13.00 per pound was used.
Step-by-step explanation:
Let x represent the number of coffee beans worth $10.50 per pound that should be mixed.
Let y represent the number of coffee beans worth $13.00 per pound that should be mixed.
50 pounds of beans worth $11.50 per pound is to be made. The total cost of the mixture would be
50 × 11.5 = 575
This means that
10.5x + 13y = 575 - - - - - - - 1
The total number of pounds of each type of coffee used is 50. This means that
x + y = 50
Substituting x = 50 - y into equation 1, it becomes.
10.5(50 - y) + 13y = 575
525 - 10.5y + 13y = 575
- 10.5y + 13y = 575 - 525
2.5y = 50
y = 50/2.5 = 20
x = 50 - 20= 30
Answer:
The area of the cover for the hot tub must be:
Step-by-step explanation:
First, you must understand that since a hydromassage tub is mentioned and the diameter, it is assimilated that it is round in its upper part, which is why the formula is used to find the area of a circle:
- <u>Area of a circle = pi * radius ^ 2</u> (you must know that the radius is half the diameter)
Since the diameter is mentioned, it can be replaced in the formula:
- Area of a circle = 3.14 * (3.5 feet) ^ 2
- <u>Area of a circle = 38,465 square feet. Approximately 38 square feet</u>.
