The volume of a cone, V , varies jointly with its height, h , and the square of its
radius, r . If k is the constant of proportionality, which of the following equations
represents the correct relationship between volume, radius, and height?
Answers
An equation is formed of two equal expressions. The equation that represents the correct relationship between volume, radius, and height is V=khr².
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given the volume of a cone, V varies jointly with its height, h, and the square of its radius, r. Therefore, the relationship can be written as,
V ∝ h(r²)
Also, k is the constant of proportionality, therefore, the equation now can be written as,
V = k×h×r²
Hence, the equation that represents the correct relationship between volume, radius, and height is V=khr².

combine like terms
5x + 15 = 90
5x = 75
x = 15
∠V = 2x+3, x=15

HELP IM LITERALLY FAILING MATH!!!
Answers
Answer:
1.4 ft
Step-by-step explanation:
Ok so first off you want to take the area(1.96) and divide it by your height(1.4)
This will get you B!(1.4)
Also since this is a square all the sides are equal!
Answer: b= 1.4
Step-by-step explanation:
Area = length x width
1.96 = “b” x 1.4
Since we have the area and one side of the box, we can rearrange the equation to find the missing side.
Since 1.4 is being multiplied on the right side of the equation, we must divide by 1.4 to remove it. Divide both sides by 1.4
1.96/1.4= b
b= 1.4

A rectangle with a width of w and a length of ? has a perimeter greater than 100.
Here is a graph that represents this situation.
Write an inequality that represents this situation.
Answers
Answer:
Let L = length
Let w = width
Perimeter = 2L + 2w
L = 100
Perimeter > 400
2(100) + 2w > 400
200 + 2w > 400 is the inequality
Subtract 200 on both sides of inequality.
2w > 200
w > 100
The width is at least 100 centimeters
The inequality that describes the perimeter of a rectangle is greater than 100 is 2(l + w) > 100.
What are the area and perimeter of a rectangle?The area of a rectangle is the product of its length and width.
The perimeter of a rectangle is the sum of the lengths of all the sides.
Given, A rectangle with a width of w and a length of l has a perimeter greater than 100.
We know the perimeter of a rectangle is 2(l + w).
∴ The perimeter of this rectangle is 2(l + w) > 100.
