In the formula for volume of a right cone, solve for the variable k: V = 1/3 * pi * r ^ 2 * h Note: In this formula, V is volume, h is height, and r is radius of the base of the cone
A. h = (3r ^ 2 * V)/pi
B. h = (3V)/(pi * r ^ 2)
C. h = (3pi * V)/(r ^ 2)
D. h = v/(3pi * r ^ 2)
The height of the cone can be written as h = 3V/(π × r²).
How to solve a linear equation?A linear equation can be solved by equating the LHS and RHS of the equation following some basic rules such as by adding or subtracting the same numbers on both sides and similarly, doing division and multiplication with the same numbers.
The formula for the volume of cone is given as V = 1/3 × π × r² × h.
It can be written in terms of h by the method of solving a linear equation as follows,
V = 1/3 × π × r² × h
=> 3V = π × r² × h
=> h = 3V/(π × r²)
Hence, the expression for height from the given formula can be written as h = 3V/(π × r²).

Answer:
Graph D
Step-by-step explanation:
The slope of the data is 2.5 because 2.5 cups of flour are used for every ounce of butter. Some points on the graph we can use is (0,0) and (10,4).
(0,0): When there are 0 cups of flour, there are 0 ounces of butter.
(10,4): When there are 10 cups of flour, there are 4 ounces of butter.
Slope=m
[tex]m=\frac{Change(y)}{Change(x)}[/tex]
[tex]m=\frac{10-0}{4-0}[/tex]
[tex]m=\frac{10}{4}[/tex]
[tex]m=2.5[/tex]
Graph D is the only graph containing the point (10,4) and (0,0). So, Graoh D is the correct graph.

Jack and Jill are both enthusiastic players of a certain computer game. Over the past year, Jack’s mean score when playing the game is 12,400 with a standard deviation of 1500. During the same period, Jill’s mean score is 14,200, with a standard deviation of 2000. They devise a fair contest: each one will play the game once, and they will compare z-scores. Jack gets a score of 14,000, and Jill gets a score of 16,000. Who won the contest, and what were each of their z-scores
Answer:
Jack won because he has the highest z score.
Their z scores was:
For Jack = 1.07
For Jill = 0.9
Step-by-step explanation:
Solving using z score formula
z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
For Jack:
Jack's mean score when playing the game is 12,400 with a standard deviation of 1500. Jack gets a score of 14,000
Jack's z score = 14000 - 12400/1500
= 1.06667
Approximately = 1.07
For Jill:
During the same period, Jill's mean score is 14,200, with a standard deviation of 2000. Jill gets a score of 16,000.
Jill's z score :
16000 - 14200/2000
= 0.9
Therefore, the person with the highest z score won and that is Jack.

Find the surface area of the equilateral triangular pryamid.
15 cm
10 cm
Answer:
268.3 cm³
Step-by-step explanation:
Surface area of triangular pyramid = Base Area + ½*(perimeter of base)(height of pyramid)
Base area = 43.3 cm²
Perimeter of base = 10 + 10 + 10 = 30 cm
Height of pyramid = 15 cm
Plug in the values
Surface area = 43.3 + ½(30)(15)
Surface area = 43.3 + 225
= 268.3 cm³

Carson's wheelbarrow can hold 345 pounds. He has p pounds of rocks in his wheelbarrow. Write the inequality to represent this situation:__
plsssssss help!!!!!!!!!!!!!!!!!!1
Answer:
umm
Step-by-step explanation:
The maximum number of pounds p is 224
Step-by-step explanation:
Let
p ----> the maximum number of pounds he can pull without going over the weight limit
we know that
121 pound of rock in the wheelbarrow plus p pounds must be at most 345 pounds
In this problem the word "at most" means "less than or equal to"
so
The inequality that represent this situation is
solve for p
subtract 121 both sides
therefore
The maximum number of pounds is 224
