Answer:

$11.70

Step-by-step explanation:

117 - 45% ( Art & Music ) = 64.35

117-64.35 = 52.65

64.35-52.65 = 11.70

Answer:

multiply 1/6 by 1/6 by 1/6 essentially

(1/6)^3

1/216

Step-by-step explanation:

Each specific bead color has (each time) a probability  of being drawn.

Hence the final probability is 1/216

Answer:

1 over 216

Step-by-step explanation:

Answer:The equation of a line is y = mx + b where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept. (Remember that the slope is the steepness  of a line and the y-intercept is the point where the line intersects  the y-axis. The x- and y-coordinates are values of the points on the line of y = 3x - 1.)

Answer:

15:12

Step-by-step explanation:

hope this helps!

The ratio of dogs and cats at the pet store is 12:15 and in simplest form, it is 4:5.

When evaluating two or more numbers, the phrase ratio is used in mathematics. When one quantity is contrasted with another, it is used to show how big or tiny it is.

The division is used to compare the two numbers in a ratio. The term "antecedent" in this context refers to the dividends and "consequent" to the divisor.

As per the given data provided in the question,

Total number of dogs in the pet store, D = 12

Total number of cats in the pet store, C = 15

The ratio of dogs to cat be,

D:C = 12:15

Now, the ratio in simplest form,

D:C = 4:5

Step-by-step explanation:

volume of cylinder is V=πr2h

volume of cone is V=πr2h

Answer:

D. 800 m

Step-by-step explanation:

Volume of a cylinder is πr²h

Here, r=10 h=8

so the volume is

=π x 10² x8

=π x 100 x 8

=800m

The answer is 800m

Answer:

π(x+2)^2

Step-by-step explanation:

The formula for the area of a circle is π*radius squared.

2x + 4 is the length across the entire circle, which would make it the diameter.

The radius is half the diameter.

So, to find out the radius, simply divide the diameter by 2.

2x+4/2

x+2

Now, plug the newly found radius into the formula.

Area=π*(x+2)^2

Answer:  your equation is poorly written/wrong hence I used the equation below

answer :  $289156.63

Step-by-step explanation:

applying the formula to calculate monthly repayment of Mortgage

M = P [ r(1+r)^n / ( ( 1+r )^n ) -1 ) ]  -----  ( 1 )

M = Total monthly payment = 800 * 12 * 30 = $ 288,000

P = ?

r = 5.2% / 12 = 0.4%

n = 30 * 12 = 360 months

Back to equation 1

P = M / [ r(1+r)^n / ( ( 1+r )^n ) -1 ) ]

   = 288000 / [ 0.004 ( 1.004)^360 / (( 1.004)^360 ) - 1 ) ]

   = 288,000 / -0.996  =  - $289156.63 ( It has a negative value because It is a loan borrowed )
