Answer:
34
Step-by-step explanation:
Answers:
680 to 578
340 to 289
250 to 212.50
Reasoning:
To find the percent of a number:
If the percentage is less than 100, we place a decimal point in front of the percent. Then, we multiply the percent by the whole.
For example, .15 x 680 = 102. Since 15% is less than 100, we place a decimal point in front of the 15. Then, we just multiplied it by the whole of 680.
We know that 102 = 15% of 680, so since that is the amount of money taken off the total, we subtract it: 680-102=578. Therefore, the new price is 578.
I did this for the rest of the questions, and there are 3 correct answers:
680 to 578
340 to 289
250 to 212.50
Area: 450m×400m= 180,000m
1m = .001km
converting meters to kilometers
180,000m× .001km= 180km
