9.3*10^34 divided by 3.1*10^17 is 3*10^17 in scientific notation :)
So you multiply because you want to find out the cost of the total amount of apples per pound bought. You multiply 3 and 1.75 and you should get $5.25 for red apples. You multiply 4.2 pounds and 1.75 and you should get $7.35 for green apples.
To find the percentage, take the part (30) and divide it by the whole (50).
Then, take the quotient and multiply it by 100.
(30 / 50) * 100 = 60%
60% of the exhibits feature birds
Answer:
The height of the telephone pole is of 408 inches = 34 ft.
Step-by-step explanation:
Each foot has 12 inches.
A 36 inch post cast a shadow of 24 inches.
This means that the shadow is of the real height.
At the same time a telephone pole cast a shadow of 22 ft 8 in.
Each feet has 12 inches, so it has:
22*12 + 8 = 272 in.
2/3 of the real height is 272 in. So
The height of the telephone pole is of 408 inches = 34 ft.
