Give the answer and explanation/ equation.
Toilet paper is sold in cases of 36 rolls for $14.99. What is the price per roll (unit cost)?

Final answer:

By dividing the total number of muffins (252) by the number of batches (7), we find that there were 36 muffins in each batch.

Explanation:

The student asked how many muffins were in a batch if a baker made 7 batches of muffins with a total of 252 muffins, and there was the same number of muffins in each batch. To find the answer, we need to divide the total number of muffins by the number of batches.

Divide 252 by 7 to find how many muffins were in each batch:

252 muffins ÷ 7 batches = 36 muffins per batch

Therefore, there were 36 muffins in each batch.

To solve for the value of x where f(x) = -22 for the function f(x) = -2x + 9, we set up the equation -2x + 9 = -22, subtract 9 from both sides, and then divide by -2, resulting in x = 15.5.

To find the value of x that makes f(x) = -2x + 9 equal to -22, we need to set the function equal to -22 and solve for x.

-2x + 9 = -22

First, subtract 9 from both sides:

-2x = -22 - 9

-2x = -31

Next, divide both sides by -2 to solve for x:

x = 31 / 2

x = 15.5

The value of x that makes f(x) equal to -22 is 15.5.

The scale of the map is found by dividing the actual length of the river by the length of the river on the map. In this case, the scale of the map is approximately 52 miles per inch.

To find the scale of the map, we need to divide the actual length of the river by the length of the river on the map. In this case, the actual length of the river is 247 miles and the length of the river on the map is 4.75 inches. So, the scale of the map is 247 miles / 4.75 inches.

Doing the division, we find that the scale of the map is approximately 52 miles per inch. This means that every inch on the map represents 52 miles in real life.

Answer:

The value of the expression [tex]0.9 \cdot (\frac{1}{2}-2)+0.6[/tex]  is  -0.75.

Explanation:

Given: the expression [tex]0.9 \cdot (\frac{1}{2}-2)+0.6[/tex]

BODMAS acronym is;

B - Bracket

O - Orders

D -Division

M - Multiplication

A - Addition

S - Subtraction  

Using BODMAS rule in the given expression, first solve the bracket terms;

[tex]\frac{1}{2} -2 = \frac{1-4}{2} = \frac{-3}{2}[/tex]

Then we have;

[tex]0.9 \cdot \frac{-3}{2} - 9[/tex]

next, multiply the terms 0.9 and [tex]\frac{-3}{2}[/tex] we get

[tex]-1.35 +0.6[/tex]

then, Add the above numbers;

[tex]-1.35 +0.6[/tex] = -0.75

Therefore, the value of given expression is, -0.75

To solve the equation -2b + 7 = -13, subtract 7 from both sides and then divide by -2.

To solve the equation -2b + 7 = -13 using the properties of equality, you would subtract 7 from both sides first to isolate the variable. This gives you -2b = -20. Then, divide both sides by -2 to solve for b. This gives you b = 10. To write the sentence 'the product of a number and 5 is 11' as an algebraic expression, you would use the equation X * 5 = 11. This represents the multiplication property of equality, where the number (X) is being multiplied by 5. The property of equality you could use to solve -3x = 348 is the division property. To isolate x, divide both sides by -3. This gives you x = -116.

To determine how many days the birdseed will last, divide the total amount (3 cups) by the daily usage (2/3 cup), resulting in 4.5 days of birdseed.

To calculate how many days the birdseed will last, you can set up a conversion factor or use division to find the answer.

Steps to Determine the Duration of Birdseed:

First, identify the total amount of birdseed you have, which is 3 cups.

Next, determine the daily usage, which is 2/3 cup per day.

Then, divide the total amount of birdseed by the daily usage: 3 / (2/3).

To divide by a fraction, multiply by its reciprocal: 3 * (3/2).

Perform the multiplication: 3 * (3/2) = 9/2.

Finally, 9/2 breaks down to 4.5, so the birdseed will last for 4.5 days.

Thus, the birdseed will sustain for approximately 4 and a half days before running out.

To answer the question, we scale up Luis's usual success ratio of 3 successful free throws out of 7 shots, resulting in 9 successful free throws out of 21 shots.

The subject of this question is a ratio, specifically Luis's free throw ratio. Luis makes 3 free throws out of every 7 shots. To figure out how many free throws Luis will make given 21 shots, we need to scale up his success ratio. If 7 shots corresponds to 3 successful free throws, then 3 times the number of shots (21) must correspond to 3 times the number of successful free throws. Thus, Luis can be expected to make 9 free throws if he shoots 21 times.

To express and evaluate given expressions in exponential form: (3/5)^2 = 9/25, (-1/6)^4 = 1/1296, (1.2)^3 = 1.728, and (-1/4)^4 = 1/256. The exponential form indicates the base number is being multiplied by itself a certain number of times.

To write each expression in exponential form and find its value, follow these steps:

For the expression 3/5 imes 3/5, since the same base (3/5) is multiplied by itself, it is written in exponential form as (3/5)^2.

To find the value, (3/5)^2 = 3/5 × 3/5 = 9/25.

The expression -1/6 × -1/6 × -1/6 × -1/6 is written as (-1/6)^4 in exponential form.

The value is (-1/6)^4 = -1/6 × -1/6 × -1/6 × -1/6 = 1/1296.

The value of (1.2)^3 is found by cubing the base: (1.2)^3 = 1.2 × 1.2 × 1.2 = 1.728.

The expression (-1/4)^4 is raising -1/4 to the 4th power, resulting in a positive value due to the even exponent: (-1/4)^4 = (-1/4) × (-1/4) × (-1/4) × (-1/4) = 1/256.
