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.

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

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.

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.

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
