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.

JJ’s Fitness Club offers two different fees for their yoga classes. Club members are charged a one-time membership fee of $24 and pay $3 per class. Non-members pay $7 per class. How many classes result in the same cost for a member and non-member?

Answers

Answer:

So the answer is 13 classes member and 9 non member

Step-by-step explanation:

so you gotta do 24 + 3x = 7y ok?

and x equals 13 so 39 + 24 = 63

and non member is 7x = 63

x = 9

Hope I helped :D

the answer is 5x. Step One: Where x equals the number of aerobics classes,
Members Nonmembers
Cost in Dollars 10+3x 0+5x
Step Two: We create an equation to solve for x.
Member Cost=Nonmember Cost
10+3x= 0+5x
Step Three: Solve for x:
10+3x= 5x Subtract 3 from both sides
10=5x-3x Combine like terms
10=2x
5=x

3. The three angles of a triangle measure x°, y° and 46°. Which of the following statements must be true?

Answers

Answer:

y=180-x is correct and finally y+x=180-46 is also correct

Step-by-step explanation:

Since all triangles add up to 180 degrees(so y+x+46=180 degrees), it cannot be the first one. The second one is correct because of fact families. And the x+y=46 is also incorrect because x+y+46 is 180 not x+y=46.

Step-by-step explanation:

Answer:

a=5260, b=52600, c=526000, d=52.6, e=5.26, f=0.526

Step-by-step explanation:

When you are multiplying by multiply of 10 (a-c) you add the number of zeros there are on the multiply of ten so for c 526000(times 1000). If it is less than 1 you just multiply the numbers and then push the decimal point however far it is in the problem so for problem f 526*1=526 and the decimal the 3 number to the right so you push it back 3 and get 0.325.

Answer:

x = 19x = 34x = 39

Step-by-step explanation:

1. A right angle has a measure of 90°. The whole is the sum of the parts.

(2x +3)° +49° = 90°

2x +52 = 90 . . . . . . . . divide by °, collect terms

2x = 38 . . . . . . . . . . . . subtract 52

x = 19 . . . . . . . . divide by 2

2. A linear pair measures 180°. The whole is the sum of the parts.

(x -5)° +151° = 180°

x +146 = 180 . . . . . . . divide by °, collect terms

x = 34 . . . . . . . . .subtract 146

3. We presume this pair of angles is supposed to be supplementary. That is, their sum is 180°.

64° +(3x -1)° = 180°

3x +63 = 180 . . . . . . . divide by °, collect terms

3x = 117 . . . . . . . . subtract 63

x = 39 . . . . . divide by 3

Jordyn got 15 out of 20 questions correct on her quiz. What percent did she get correct? (Provide the % symbol in your answer)

Answers

Answer:

75%

Step-by-step explanation:

Hello!

I'd love to help.

An easy method to finding a percentage is converting it into a decimal.

First though, we must simplify 15/20, which would be 3/4, (please let me know if you need the process of simplification)

Then we find the decimal.

We divide the numerator by the denominator.

3 ÷ 4 = .75

Which means that our final answer is:

75%
