Answer:
-6/5, 0, 6/5
Step-by-step explanation:
- First factor out the d and you are left with d(25d^2-36)=0
- (a+b)(a-b) = a^2-b^2
- Using that principle you can then simplify further by factoring it into d(5d+6)(5d-6)=0
- Then just solve to get the answers.
Answer:
1727 inches or approximately 143.91667 feet
Step-by-step explanation:
circumfrence is the so its . this gives you a circumfrence of 69.08 inches which is eaual to one revolution. you simply have to do inches. I didnt know if you also needed the answer in feet, so i divided that by 12 to get an approxamation of 143.91667 feet (it comes out with a repeating 6, so i rounded it to 7 on the third to six be accurate).
Answer:
23 degrees
Step-by-step explanation:
First, subtract 9 from 29 to find the temperature at 9 A.M. The temperature at 9 A.M. was 20 degrees. The temperature from 5 A.M. doubled to get to the temperature at 9 A.M., so divide 20 by 2. The temperature at 5 A.M. was 10 degrees. The temperature from midnight to 5 A.M. fell 13 degrees, so add 13 to get the temperature at midnight. 13+10=23. It was 23 degrees at midnight.
1/2x14=7, 14x3.45=48.3 so it would cost $48.30
