A fast typist can type 120 words in 100 seconds. At that rate, how many seconds would it take to type 258 words?
Alexeev081 [22]

Answer: 215 seconds

Step-by-step explanation:

This is a ratio problem so you can set up the ratio like this:

120 words : 100 second.

If you divide both sides of the ratio by 120 you get:

1 word: 0.8333 seconds

Multiply both sides of the ratio by 258 and you get:

258 words: 215 seconds.

Therefore typing 258 will take them 215 seconds.

Find the circumference of the circle.
SashulF [63]

Answer:

  • The circumference of the circle in term of pi = 10π inches
  • The circumference of the circle us 3.14 as pi = 31.4 inches

Step-by-step explanation:

Given

The radius of the circle = r = 5 in

We know that diameter is twice the radius.

so d = 2r = 2(5) = 10 in

<u>Finding the circumference of the circle in terms of pi</u>

Using the formula to find the circumference of the circle

C = dπ

C = 10×π

C = 10π inches

Thus, the circumference of the circle in term of pi = 10π inches

<u>Finding the circumference of the circle using π = 3.14</u>

We know that the formula to find the circumference of the circle

C = dπ

Given

π = 3.14

substituting π = 3.14 to find the circumference of the circle

C = 10×3.14

C = 31.4 inches

Thus, the circumference of the circle = 31.4 inches
