Answer:

C:30π cm  

Step-by-step explanation:

The formula for the circumference of a circle is

C = 2πr

Since the radius is 15 cm, this makes 2r = 2(15) = 30 cm.  This makes the circumference

C = 30π cm

Answer: C: 30π cm

Step-by-step explanation:

The circumference of a circle is given by :-

C= 2\pi r , where r is the radius of the circle.

We are given that : The radius of the circle = 15 cm

then , the circumference of the circle will be :-

C= 2\pi (15)\ cm\\\\\Rightarrow\ C=2\times15\pi\ cm\\\\\Rightarrow\ C=30\pi \cm

Therefore, the exact circumference of a circle with a radius of 15 cm = 30\pi \cm

Thus , the correct option is C: 30π cm

Please help me with this I need to find out what y is
julsineya [31]

Answer:

26°

Step-by-step explanation:

<DFG+<EFG = 180°( Being sum of adjacent angle in linear pair is 180°)

You can also write;

<DFG+<EFG = 180°( Being sum of supplementary angle is 180°)

By putting the value of those angles;

5y+3+(2y-5)=180

5y+3+2y-5=180

5y+2y-5+3 =180°

7y-2=180°

7y=180+2

7y=182

y=182/7

y=26°

Hence,

The value of y is 26°

the original price of a jacket is $68. The sale price is 30% off the original price. what is the amount off the original price?​
Semmy [17]

Answer: The original price of the jacket is given in the question and it is $68.

The percent of discount given on the original price is 30%.

Then

The amount of discount given = (68 * 30/100) dollar

                                                = 20.4 dollar

The discount amount is $20.4

Now after the deduction of the sale percentage, the selling price of the jacket can be easily deduced.

Then

Selling price of the jacket = (68 - 20.4) dollars

                                        = 47.6 dollars

Answer:

a=21

AB=23.9

BC=19.5

CD=(23.9)

AD=19.5

Step-by-step explanation:

Each pair of parallel sides are equal in a parallelogram. Sense both pairs use the same variable we can just choose the easiest to solve which would be:

a-1.5=19.5

add 1.5 to both sides

a=21

now substitute 21 in for a in each equation.

AB=CD so

AB=23.9

BC=AD so

BC=19.5

CD=(21)+2.9 so

CD=(23.9)

AD is given so

AD=19.5

Let $ 500 be paid at the end of each quarter for 5 years. If the interest is earned rate of 13%, compounded quarterly, find the
kap26 [50]

Answer:

Future value of annuity (FV) = $13,782.12 (Approx)

Step-by-step explanation:

Given:

Periodic payment p = $500

Interest rate r = 13% = 13%/4 = 0.0325 (Quarterly)

Number of period n = 5 x 4 = 20 quarter

Find:

Future value of annuity (FV)

Computation:

Future\ value\ of\ annuity\ (FV)=p[\frac{(1+r)^n-1}{r} ] \\\\Future\ value\ of\ annuity\ (FV)=500[\frac{(1+0.0325)^{20}-1}{0.0325} ] \\\\Future\ value\ of\ annuity\ (FV)=13,782.1219 \\\\

Future value of annuity (FV) = $13,782.12 (Approx)
