Answer:

C = -13.78

Step-by-step explanation:

Answer:

c = -13.78

Step-by-step explanation:

21.2x + c =5.3(4x - 2.6)

Use distributive property: a*(b + c) = (a*b) + (a * c)

21.2x + c = 5.3*4x - 5.3*2.6

21.2x + c = 21.2x - 13.78

Now to find the value of c, isolate 'c'. So, subtract 21.2x form both sides

21.2x + c - 21.2x = 21.2x - 13.78 - 21.2x

c = -13.78

Find the area of a circle with a diameter of 6 feet. Find both the exact area and the area rounded to the nearest

Answers

Answer is =28.27433ft²

Step-by-step explanation:

A≈28.27ft²(Answer)

Diameter

Using the formulas:

A=πr2

d=2r

Solving for A

A=1

4πd2=1

4·π·62≈28.27433ft²

To answer this question we need to use a basic formula to find the area of a circle which is:
pii*radius*radius

Steps:
1. Find the radius

Divide 6 (diameter) by 2 since 2 radius makes up a diameter, so you would get 3 has the radius.

2. Substitute the values

3.14 * 3*3
Which equals 28.26.

Answer:
Exact area—28.26 ft (squared)

Rounded to the nearest tenth—28.3 ft (squared)

Hope this helps!!

Answer:

Rick Astley measures a window's front side to be 12 feet in length by 3/8 feet in width. What is the surface area of the window?

Step-by-step explanation:

You don't have to use Rick Astley, but you can if you want ;)

Aswer: 4.5 ft^2

Answer is below. Look at the explanation to understand my answer.

To multiply fraction, you'll need to multiply the numerator by the other numerator and the denominator by the other denominator. You don't need to make the denominators common.

Normally you'll multiply the numerator and the denominator, but for this, 12 is a whole number. To convert it into a fraction, put 1 as the denominator.

12 will now be ¹²⁄₁.

Remember, you don't need to make common denominators. Only for subtracting and adding fraction with unlike denominators.

Our problem will be like this: [tex]\frac{12\times3}{1\times8}[/tex]

With that being said, let's solve.

12 times 3 equals 36.

1 times 8 equals 8.

Our answer is ³⁶⁄₈, but it is improper. We will need to convert it into a mixed number by dividing the numerator by the denominator.

Find the Greatest Common Factor (GCF) of 36 and 8. If there is, reduce the fraction dividing both numerator and denominator by it.

Therefore, the GCF is 4.

Whatever you do to the top, You do to the bottom.

Our problem will be this: [tex]\frac{36\div4}{8\div4}[/tex]

36 divided by 4 is 9.

8 divided by 4 is 2.

Hence the fraction is ⁹⁄₂, but the fraction is still improper. Instead of finding the GCF, we will use long division.

We will divide 9 by 2 to get the answer.

9 divided by 2 is 4 with a reminder of 1.

The reminder will be the numerator, the denominator will be the same, and the quotient, or the answer will be the mixed number.

Therefore, our final answer is 4 ½.

28 out of 50 8th graders said they prefer snow to rain. 42 out of 58 10th graders said they prefer snow. did a larger percentage of 8th graders or 10th graders prefer snow?

explanation please

Answers

A larger percentage of 10th graders preferred snow.

Answer:

10th graders prefered snow then 8th graders did.

Step-by-step explanation:

Hey I hope I will be able to help!

To find out the percentage we need to divide the fractions-

28 divided by 50 = 0.56 and in percentage form its 56%

42 divided by 58 = approximately 0.72 which is 72%

56% < 72%

72% is obviously greater so 10th graders prefer snow more than 8th graders do.

4 chef require 10 minutes to prepare 20 desserts. At this rate how many chefs are needed to prepare 75 desserts in 15 minutes?

PLS HELP! PLS TELL ME HOW YOU GOT THE ANSWER. THIS IS FOR MY COUSIN. SHE NEEDS HELP.

Answers

So right now, you need 4 chefs to prepare 20 deserts in 10 minutes (so the rate is one chef can make a dessert in 2 minutes) so if we think about this 7.5 desserts can be made by one chef in 15 minutes, BUT no one wants 1/2 of a dessert, so we must round this down to 7, and now we divide 75 by 7 to get 10.7, but we don’t want 0.7 of a cheap, so we round up to get 11 chefs can make 75 desserts in 15 minutes

The number of chefs that are needed to prepare 75 desserts in 15 minutes is; 10 chefs

According to the question;

4 chefs require 10minutes to prepare 20 desserts

For the scenario above; This means;

4 chefs are able to prepare 2 desserts/minute.

The question requires that we determine how many chefs are needed to prepare 75 desserts in 15 minutes.

In essence;

x chefs are able to prepare (75/15) = 5 desserts/minute.

Therefore;

x = (5 × 4)/2

x = 10 chefs

Ultimately, 10 chefs are needed to prepare 75 desserts in 15 minutes.
