For this case we can make the following rule of three:
21 ------> 70%
x --------> 100%
Clearing x we have:
x = (100/70) * (21)
Rewriting we have:
x = (10/7) * (21)
x = 30
Thus,
21 is 70% of 30
Answer:
21 is 70% of 30
A;
Absolute value of 4is 4 />Absolute value of -4is greater than 4
Written out, this would be (x / 7) - 10 < -6
solved, it would be x < 28
Answer:
12
Step-by-step explanation:
5+7=12
5 have 7-14
7 have 15-22
The final answer is 12
The dimension from 8 inches to actual size is 8 * 15 = 120. 14.5 inches to actual size is 14.5 * 15 = 217.5.
Then, you multiply 120 to 217.5 to get 26100 square miles.
The answer is D.
