4. The three angles of a triangle measure x°, y° and 39°. Which of the following statements must be true?
A. y=x+39
b. y+x=180-39
C. x+y=39
D. y=180-x

Answers

Answer 1

Answer:

It is: C. x + y = 39

Step-by-step explanation:

Since the first angles are always added unless they are in a fraction, but since that is not the case they are added and gives 39.

And if you want to know the measures of x, y.

X: is 55º

Y: it is 79º

I hope I have helped.

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.

18*7.5*4 = 540, 540 cm^3

2. Volume of triangular prism is surface area of base times length

the length is 14 cm, and the base is the triangle, The area of a triangle is half of the base times the height, 1/2b * h. The base of this triangle is 8 cm, and the height is also 8 cm, 1/2(8) * 8 = 4*8 = 32, 32 times the length of the triangle is 32*14 = 448 cm^3

In the following inequality, x ≥ −2, what type of circle would appear on the number line (open or closed circle) and in which direction would the arrow point on the number line(right or left)?

Also, what is a possible solution to x ≥ −2?

Please answer all of the questions in sentence form.
(10 Points)

Answers

Answer:

A closed circle would appear on the number line and the arrow should be pointing towards right. The possible solutions could be basically anything greater than or equal to -2, it could be -2, -1, 0, 1, 2, 3, 4 and so on.

Step-by-step explanation:

There are a few things to consider:

1. The inequality symbol:

⇒      [tex]\leq or \geq[/tex] always represented by a closed circle on the number line (this also means that the function x ≥ −2 would contain values greater than -2 but it WOULD also include -2 as an answer, but anything less than -2 would not be included).

⇒      < or > always represented by an open circle on the number line (This also means that the function would contain all numbers greater than -2 but NOT -2 or anything greater).

2. Where the Inequality sign opens:

⇒      If the inequality sign opens towards the variable (a letter) it means that all the values will be greater than the value given in the function. (For example x > 2, since the inequality sign is opening towards the x it means that all values in the solution set would be greater than two and thus the arrow would face the right side. The possible solution set could be 3, 4, 5 and so on)

⇒       If the inequality sign opens towards the number value given, it means that all the values will be less than the value given in the function. (For example, x < 2, in this case the inequality faces towards the number value given so the values for the answer set will have every value less than 2, the solution set would contain values like 1, 0, -1, and so on).
