Answer:

B. 15 ft.

Step-by-step explanation:

We have been given that the circumference of a circle is 47.1 feet. We are asked to find the diameter of the circle.

We will use circumference of circle formula to solve our given problem.

$C=\pi D$

Upon substituting the measure of circumference in formula, we will get,

$47.1=3.14* D$

Now, we will divide both sides of our equation by 3.14.

$\frac{47.1}{3.14}=\frac{3.14* D}{3.14}$

$15=D$

Therefore, the diameter of our given circle is 15 feet and option B is the correct choice.

You are given that <GHJ is a complement of <RST and <RST is a supplement of <ABC. Let m<GHJ be x°. What is the me

MAVERICK [17]

∠GHJ and ∠RST are complementary

⇒ ∠GHJ and ∠RST = 90°

And ∠RST and ∠ABC are supplementary

⇒ ∠RST and ∠ABC = 180°

Also, ∠GHJ = x°

⇒ ∠RST = 90° - x°

⇒ ∠ABC = 180° - ∠RST

⇒ ∠ABC = 180° - (90° - x°)

⇒ ∠ABC = 90° + x°

Seth bought a 12 - ounce jar of peanut butter for $3.60. What is the unit price?

allochka39001 [22]

Since the jar is 12 ounces, we want to find the price when it is one ounce. We do this by dividing the price, $3.60, by 12:

3.60/12 = 0.3

So, the answer is $0.30/oz, or (B).

Evaluate the function k(x)=5 for the given value of x. Simplify your answer.

coldgirl [10]

Answer:

Step-by-step explanation:

k(x)=5 says I'm 5 no matter the value of x...

So therefore

k(-4)=5

k(56)=5

k(66378)=5

k(whatever)=5

k(x) is constantly 5 for whatever input x.

The balance on Taylor's credit card is $2000. It has an interest rate of 12.5%. She wants to compare the difference between payi

-Dominant- [34]

Answer: kindly check Explanation

Step-by-step explanation:

The balance on card = $2000

Interest rate = 12.5%

Therefore, monthly rate = 12.5% / 12 = 0.0104167

Paying $75 of monthly balance :

Interest amount on 2000 = 0.0104167 × 2000 = $20.83

Therefore,

Principal amount payed = 75 - 20.83 = 54.17

Balance = ($2000 + $20.83) - $75 = 1945.83

Interest on balance = 0.0104167 × 1945.83 = $20.2691

Paying $100 of monthly balance :

Interest amount on 2000 = 0.0104167 × 2000 = $20.83

Therefore,

Repayment = 100 - 20. 83 = $79.17

Balance = ($2000 + $20.83) - $100 = 1920.83

Interest on balance = 0.0104167 × 1920.83 = $20.0087

Interest saved by paying $100 instead of $75

$20.27 - $20.00 = $0.27 = 27 cent
