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.

Suki’s method is the best to use here. Dinah could only know students who read novels, making her sampling method more biased.

Suki’s method is definitely the better choice. It was randomly selected and includes a greater amount of students. Dinah’s method has a little more bias. It’s about the people SHE personally knows, and because of the variables in the survey (same class as Dinah? Is she in a higher education class? Part of a group?) So the answer is Suki. Once again, greater amount of participants, randomly chosen without any bias

Tell whether the angles are complementary or supplementary. Then find the value of x.

this just confused me a bit. x - 20? They are complimentary so ik the other side has to be 20

Answers

As you should already know that the angle shown is 90°.

So,

x + (x - 20) = 90

Now we have to solve for x. To find x we need to isolate it (get it by itself)

Add 20 on both sides:

x + x = 110

Simplify:

2x = 110

Now divide 2 on both sides (to get x by itself)

x = 55

Let’s check our answer:

55 + ( 55 - 20) = 90

55 + 35 = 90

90 = 90

So your answer should be x = 55.

Benjamin believes that 1/2 % is equivalent to 50%. Is he correct? Why or why not? Please explain.

Answers

Answer:

Benjamin is correct.

Step-by-step explanation:

1/2 converted to a decimal (1 divided by 2) is 0.50, which when converted to a percentage is 50%.

1 ÷ 2 = 0.5

.5 × 100 = 50 ⇒ 50%

So, 1/2% = 50%

Also, 1/2 is 50%. So, that should automatically prove that he is correct.

Hope this helps! :)

points at (2,6) (3,9) (7,21) (8,24)

Step-by-step explanation:

Answer:

Step-by-step explanation:

each line is 1, so in between 0 and 5, the numbers 1-4 are there.

Coordinate place (x,y), the x is the horizontal or just the one going left and right. Y places are the numbers going up and down.

Take (2,6), we go to the origin (0,0) and we go 2 to the right since its in the x place, then we go from the point where we moved and go up 6 since its a y.

does that make sense?

b) 52600

c) 526000

d) 52.6

e) 5.26

f) 0.526

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.

51. Find the length of the unknown side x of this triangle, evaluate your answer to two decimal places.

Answers

Answer:

See work, below.

Step-by-step explanation:

The radius of this circle is 10 and so the diameter is 20. The measure of the angle opposite side x is found as follows:

adj side

cos theta = ------------------- = 18/20. Find theta:

hypotenuse

theta = arccos 18/20 = 0.451 radian.

Now use the sine function to find x:

x x

sin 0.451 radian = ------------------- = ------------- = 0.651

hypotenuse 20

which results in x = 20(0.651) = 13.02

x = 13.02 units

I should have used the Pythagorean Theorem up front.

18² + x² = 20² becomes x² = 400 - 324 = 76, and so x = √76 ≠ 8.72
