Answer:

20, 12, and 16

Step-by-step explanation:

So we know that y=4x

This basically means y=4*x

So we can plug the values for x shown on the table below to find y.

when x=5:

y=4*5

y=20

So for the first fill in box, its 20

Next is x=3:

y=4*3

So for the next fill in box it is 12.

Finally we have x=4:

y=4*4

y=16

So the for the finally box it is 16.

Hope this helps!

Answer:

5 - 20

3 - 12

4 - 16

This problem requires you to utilize the equation for the volume of a sphere. The volume of a sphere is [tex]\frac{4}{3}\pi r^{2}[/tex].

8x+4.79=60.39

Step-by-step explanation:

If you want this solved,

60.39-4.79 = 55.6

pencils for $9.12

.Find the unit price for each brand. Then state which brand is the better buy based on the unit price.

Round your answers to the nearest cent.

Answers

Answer: The brand should would want to pick is brand A.

Step-by-step explanation: Okay, first you divide 28 by $4.19. Then, divide brand B (72 divided by $9.12). Brand A- 6.68 | Brand B- 7.89.

Brand A: 0.14$ for 1 pencil
Brand B: 0.12$ for 1 pencil

Brand B is the better buy because it costs less per one pencil.

The figure below shows a shaded circular region inside a larger circle:
r3 inches
R5 inches
What is the probability that a point chosen inside the larger circle is not in the shaded region?
O 24%
O 36%
O 50%
O 64%

Answers

Answer:

Probability is 64%

Step-by-step explanation:

Given the smaller circle which is shaded whose radius is denoted by r and the largest circle whose radius is denoted by R

r = 3 inches

R = 5 inches

Step 1 : To calculate the area of shaded region.

Area of circle =

⇒ Area =

= square inches

Step 2 : To calculate the area of larger circle.

Area of circle =

⇒ Area =

= square inches

Step 3 : Calculate the probability that a point chosen from shaded region

Probability = Area of shaded region/Area of larger circle.

= /

= 0.36 = 36%

Step 4 : calculate the probability that a point chosen inside the larger circle is not in shaded region.

Probability = 1 - 0.36

= 0.64 = 64%

Hence the probability is 64%

Answer:

19.5°

Step-by-step explanation:

The sum of any 3 angles of a triangle is 180.

That being so 33.5 + 127 + F = 180.

33.5 +127 + F - 33.5 = 180 - 33.5

127 + F = 146.5

127 + F - 127 = 146.5 - 127

F = 19.5

For a chess tournament, there needs to be 3 teachers for every 18 students. If there are 11 teachers, how many students can go to the chess tournament?
What is the constant of proportionality? You can think about this as 18 is how many times as much as 3.
Number of Teachers Number of Students
3
×
18
11

Answers

Step-by-step explanation:

Solution:

Given,

3 Teacher = 18 students

11 Teacher = X students ( let no. of student be x)

Now,

1 teacher = 18/3

= 6 students

So, If 1 teacher is there then 6 students can play chess.

again,

No. of teacher = 11

No.of students = X

Now,

X= No.of teacher × No.of students for 1 teacher.

= 11 × 6

= 66

So , 11 Teachers can handle 66 students.

There propotion is 11/66 = 1/6 = 1:6.

Answer:

1:6 is the answer

(if he gathers 4 coins each month you will need the variable by it. he was given 20 coins so it is added on to how many coins he has. plus it would be greater than because the question asked when he will have MORE than 50 coins.)

The answer to this problem is D.

We know that each month, he gets 4 coins to add to his collection so that would represent 4m. And we know that he started with 20. The last thing that we know is that we will need a greater than symbol to represent more than 50. Therefore the equation is
20 + 4m > 50.

The area of the figure is 28.5 meters squared
Explanation
Divide the figure into two triangles and a rectangle.

The area of the triangle at the top is:
6 x 2 /2= 6

The area of the triangle on the right is:
3 x 3 /2= 4.5

The area of the rectangle on the center is:
3 x 6 = 18
