Volume of a cone is given by the formula
V=1/3πr²h
we are given a radius of 5 and a height of 4 so we will just substitute for the values and we will give our pie as 22/7
V=1/3× 22/7×5²×4

A recipe calls for 2 1/4 teaspoons of baking powder per serving. You have 9 teaspoons of baking powder. You want to make 4 1/4 servings. Do you have enough baking powder?
You do not have enough baking powder.
Do you have enough baking powder?A mixed number is a value that is made up of a whole number and a proper fraction. A proper fraction is a fraction in which the numerator is less than the denominator. An example of a mixed number is 1 1/2.
In order to determine if you have enough baking powder, multiply 2 1/4 by 9. The teaspoons of baking powder that is needed for 4 1/4 servings = teaspoons needed for one serving x number of serving
2 1/4 x 4 1/4
= 9/4 x 17/4 = 153 / 16 = 9 9/16
9 9/16 is greater than 9 so you do not have enough baking powder.

A cylinder has a height of 12 inches. A similar cylinder has a height of 15 inches. What is the ratio of the surface area of the larger cylinder to the surface area of the smaller cylinder?
The ratio is 15+\(r_2\) : \(12+r_1\).
What is surface area?
A three-dimensional object's surface area is the space it takes up when viewed from the outside.
Here surface area of the cylinder = \(2\pi rh+2\pi r^2\) square unit
=> A = \(2\pi r(h+r)\) square unit.
Now Height = 12 in , radius = r1 then,
=> \(A_1 = 2\pi r_1(12+r_1)\) -----> 1
Now Height = 15 in , radius = r2 then,
=>\(A_2=2\pi r_2(15+r_2)\)-------> 2
Now the ratio of the surface area of the larger cylinder to the surface area of the smaller cylinder then,
=>\(2\pi r_2(15+r_2) : 2\pi r_1(12+r_1)\)
=>\(15+r_2:12+r_1\)
Hence the ratio is \(15+r_2:12+r_1\).

Answer:
1/6 of a cup
Step-by-step explanation:
You're trying to figure out what 1/3 subtract 1/2 is, right?
Well first, convert both of them so they both have the same denominator.
Common Denominator = 6
So, 1/3 is 2/6 and 1/2 is 3/6 and 2/6 plus 3/6 is 5/6. Well, what's left in the cup? 6/6 subtract 5/6 is 1/6

Answer: 6/(6+2x) ; (-infinity, -3) U (-3, infinity)
Step-by-step explanation:
(a) This can be read as f(x) composed of g(x). Plug in the expression given for g(x) for every x value in f(x):
(6/x)/(6/x+2)
I gave the terms in the denominator the same denominator to combine the bottom two terms into one term. 6/x + 2 is equal to 6/x + 2x/x -->
(6 +2x)/x
Do the classic keep, change, flip. \(\frac{6}{x} * \frac{x}{6+2x}\)
This simplifies to: \(\frac{6}{6+2x}\)
(b) Domain is all real numbers except for what makes the denominator equal to 0. 6 + 2x = 0 when x = -3. Therefore it is all real numbers except -3.

why are inverse realashinships between operations used to solve twop step inqualites
Inverse relationships between operations are used to solve two-step inequalities because they allow us to isolate the variable on one side of the inequality.
A two-step inequality involves two operations that need to be undone in reverse order to solve for the variable. Inverse relationships between operations are used to "undo" these operations, leading to an isolated variable.
For example, consider the inequality 2x + 5 > 11. The first operation being performed on x is multiplication by 2, and the second operation is adding 5. To solve for x, we need to undo these operations in reverse order.
The inverse relationship of multiplication by 2 is division by 2, and the inverse relationship of adding 5 is subtracting 5. Therefore, we can solve the inequality as follows:
2x + 5 > 11
2x > 6 (subtract 5 from both sides)
x > 3 (divide both sides by 2)
Here, we first subtracted 5 from both sides to undo the addition of 5, and then divided both sides by 2 to undo the multiplication by 2.
Inverse relationships between operations are used in two-step inequalities because they help to simplify the equation by undoing the operations one by one, leading to an isolated variable.
By using inverse relationships between operations, we can efficiently and systematically solve two-step inequalities and isolate the variable to find the solution set.

Answer: x = 10
Step-by-step explanation:
To solve, we will isolate the variable x.
Given:
2x + 7 = 5x - 23
Add 23 to both sides of the equation:
2x + 30 = 5x
Subtract 2x from both sides of the equation:
30 = 3x
Divide both sides of the equation by 3:
10 = x

Peter is going to visit 5 cities this summer. He will choose from 7 different cities, and the order in which he visits the cities does not matter. How many different city combinations are possible for the summer traveling?
There are 21 different city combinations possible for Peter's summer traveling.
To determine the number of different city combinations possible for Peter's summer traveling, we need to calculate the number of combinations of choosing 5 cities out of the 7 available cities.
Since the order in which he visits the cities does not matter, we are dealing with combinations rather than permutations.
The formula to calculate the number of combinations is given by the binomial coefficient, also known as "n choose k," denoted as C(n, k) or (nCk).
In this case, we have 7 cities to choose from, and Peter will visit 5 cities. Thus, we can calculate the number of city combinations as follows:
C(7, 5) = 7! / (5! * (7-5)!)
= 7! / (5! * 2!)
= (7 * 6 * 5!) / (5! * 2)
= (7 * 6) / 2
= 42 / 2
= 21

A recipe for orange water says, “Mix 3 teaspoons of yellow water with 1 teaspoon red water.” For this recipe, we might say: “The ratio of teaspoons of yellow water to teaspoons of red water is 3:1.” 1. Write a ratio for 2 batches of this recipe. 2. Write a ratio for 4 batches of this recipe
Well, we know that 3:1 is one batch of orange water. We also know that there are 2 things to focus on.
1. Must write ratio for 2 batches of the recipe.
2. Must write ratio for 4 batches of the recipe.
To make this equation simple, double the ratio to find 2 batches because all it means is 2x more water.
3:1
x2
6:2
So, the ratio would be 6:2 to make 2 batches.
To make it easier again, we just multiply the ratio of 2 batches by 2 which would find the ratio for 4 batches.
6:2

12:4
So that means, that it is 6:2 for 2 batches, and 12:4 for four batches.
