The town library is having a used book sale. The Graph below can be used to find the cost y to buy x books. The total cost includes the admission fee. What is the equation of the line shown?
A: y = x + 4
B: y = x - 4
C: y = -x + 4
D: y = -x - 4

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.)

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]

Answer:

C

Step-by-step explanation:

Answer:

7 over negative 8.

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:

City

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

To calculate a gratuity or tip on any calculator it is a simple multiplication. In general, the tip amount is the cost times 0.xx and your total including tip, is the cost times 1.xx where xx = the percent you want to leave.  If you want to leave a 20% tip, multiply the cost by 0.20 to get the tip amount or multiply the cost by 1.20 to get the total including tip. If you want to leave a 18% tip, multiply the cost by 0.18 to get the tip amount or multiply the cost by 1.18 to get the total including tip.

Let's say you and a friend had dinner that cost $26.50.  You had good service and want to leave an 18% gratuity.  Put the percentage in decimal form (0.18) then multiply the cost by this number.

26.50 * 0.18 = 4.77.  So your tip is $4.77.

An easy way to get the total amount, dinner plus tip, is to multiply the total by 1.18. 26.50 * 1.18 = 31.27.  This works mathematically because you want to know your original cost plus the tip which is written as 26.50 + (26.50 * 0.18) = ?  Factoring out the 26.50 from this equation you get 26.50 * (1 + 0.18) = 26.50 * 1.18.

How to calculate a tip in your head

You can get a good approximation of a tip by doing it in your head this way.

You can find 10% of your bill by moving the decimal one place to the left.  If 26.50 is 100% then 10% is 2.65.  Since 20% is 2 times 10%, 20% of the bill is 2.65 + 2.65 = 5.30.  Now you know the tip you could leave ranging from poor to good, $2.65 to $5.30.  To find 15%, halfway in between, we know 15% is 10% plus 1/2 of 10% (5%).  2.65 plus about 1.30 is 3.95.

Now you have

10% is 2.65 - by moving decimal 1 place left

15% is 3.95 - 10% + 1/2 of 10%

20% is 5.30 - 10% * 2

This is plenty of information to make a good guess at the tip amount you should leave.  If you decide on about 18%, 4.50 to 5.00 would be a safe guess.

Answer:

put to percentage as a decimal (ex. 0.18) then you add that to the total amount

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

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:

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%
