Step-by-step explanation:

2.5 times 6 is 15 then you do 6 times 100 which equals 600

600 words

Step-by-step explanation:

first you need to find the unit ratr, how many words does she type in 1 minute?

100/2.5=40

sylvia types 40 words in one minute

answer: about 22.67

step-by-step explanation:

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
