Answers:

pi/3 radians = 60 degrees
pi/4 radians = 45 degrees
pi/2 radians = 90 degrees

=======================================

Explanation:

To apply the conversion, we use the idea that pi radians is equivalent to 180 degrees

pi radians = 180 degrees

To convert from radians to degrees, we'll multiply by the conversion factor (180/pi)

This leads us to the following:

(pi/3 radians)*(180/pi) = (pi*180)/(3*pi) = 180/3 = 60. So pi/3 radians converts to 60 degrees
(pi/4 radians)*(180/pi) = (pi*180)/(4*pi) = 180/4 = 45. So pi/4 radians converts to 45 degrees
(pi/2 radians)*(180/pi) = (pi*180)/(2*pi) = 180/2 = 90. So pi/2 radians converts to 90 degrees

Correct Answer: Option A

Principal Amount = P = $23,400
Interest rate = r = 3% = 0.03
Time = t = 10
Number of compounding periods in a year = n = 2
Compounded amount = A = ?

Formula for compound interest is:

$A = P(1+ \frac{r}{n} )^{t*n}$

Using the values, we get:

$A=23400(1+ \frac{0.03}{2})^{2*10}=31516.41$

Option A is the closest one, so its the correct answer

A pizza buffet has prepared 15 pizzas to place on the line at the beginning of lunch at 11:00 a.m. The equation used to describe

Anit [1.1K]

Answer:

B. Every 16 minutes, 22 more pizzas were set out on the buffet.

Step-by-step explanation:

At 11:00 am, x would be equal to 0, and there would be 15 pizzas on the buffet line. Then, every 8 minutes, 11 more pizzas are added to the buffet line. So in 16 minutes, 22 pizzas will be added to the buffet.

$\frac{16}{8} =2\\(11)(2) = 22$
