Answer:

$13.90

Step-by-step explanation:

1.20 *1.20= $2.40 tax

30.20-2.40= $27.8 (both cds)

27.8/2 = $13.90 per CD

Answer:

40.5 Please mark me as brainliest

Step-by-step explanation:

x=(7/8)-(1/5)

x=(7*5-1*8)/40

x=(35-8)

x=(27/40)

60 min= 1hr

(27*60)/40

=40.5 min

Answer :  40.5

Step-by-step explanation:

Cost for 12 months

City

150 + (30 * 12) = 510

Urban

50 + (40 * 12) = 530

City is $20 less for the year

Answer:

a and c

Step-by-step explanation:

Answer: C) 15

Step-by-step explanation:

Use the Pythagorean theorem

[tex]x^{2}[/tex]= [tex]12^{2}[/tex] + [tex]9^{2}[/tex]

[tex]x^{2}[/tex] = [tex]225[/tex]

[tex]x = \sqrt{225}[/tex]

[tex]x = 15[/tex]

Step-by-step explanation:

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

=

12

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

There are 8 big fish for every 10 small fish, There are 4 big fish for every 5 small fish.

A proportion is a fraction of a total amount, and the measures are related using a rule of three. The relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

We need to find the number of small fishes for 4 big fish.

We can see that the big fish and small fish numbers are in proportion to each other.

Assume the small fish corresponding to 4 big fish be 'x'.

Therefore, using the proportion of two quantities, we have;

[tex]\dfrac{8}{10}=\dfrac{4}{x}[/tex]

Now on cross multiplying we get:

8x = 4×10

8x =40

Dividing both sides by 8, we get:

x=5

Hence, there are 4 big fish for every 5 small fish.

#SPJ5

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

Answer: G

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]. Because we are given the radius, the equation should be [tex]\frac{4}{3}\pi 12^{2}[/tex]. Simplify the equation to get 7238.23 [tex]cm^{3}[/tex]. (The mass doesn't really matter in this scenario. It's just additional information.)

Step-by-step explanation:

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%
