If you want this solved,

60.39-4.79 = 55.6

55.6/8 =6.95

One bag of onions = $6.95

(just for extra because I'm tired)

The answer is 8x + 4.79 = 60.39

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

Answers

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!

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.

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

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 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%
