Suppose a wall in Pompeii has 150 words written on it. If 40 percent of the words were written
with charcoal, how many of the words were not written with charcoal?
A
40 words
B 90 words
C 60 words
D
36 words

c

Step-by-step explanation:

40% can be written as 40/100

to find 40% of 150, you have to set a proportion

40/100=x/150

cross multiply the terms and you get

100x=6000

divide both sides by 100

x=60 so c

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm

the answer is 1/4
