Ms. Kwok spend $2.88 for a dozen pencils. What is the cost per pencil?

$0.24

Step-by-step explanation:

A dozen pencils is 12 pencils and if we need to know the cost per pencil we have to divide the total price by the number of pencils

2.88 ÷ 12 = .24

That means each pencil is 24 cents

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
