Firstly we need to realize that 17/25 is as much as 68/100 (because 4 * 17 = 68 and 4 * 25 = 100). Now we can write it as a decimal of 0.68.
0.68 is a terminate decimal because there is no other digit than 0 we can add on its right hand side.
Answer:
350 students
Step-by-step explanation:
1400 / 4 = 350
The areas are as follows:
Deck 1: 5 * 5 = 25ft squared
Deck 2: 5 * 7 = 35ft squared
Deck 3: 5 * 9 = 45ft squared.
They increase by 10ft squared each time.
Assuming the numbers after 10 are exponents:
1 million is equal to 10^6. Let's multiply this by the original expression.
8.7*10^4*10^6
Add exponents when multiplying with the same base
10^4*10^6= 10^10
Final answer: 8.7*10^10, or D
Answer:
9
Step-by-step explanation:
The slopes are perpendicular lines are opposite reciprocals.
If one line has slope - 1/9, then the perpendicular to it has slope 9/1 or 9.
