20 bags of popcorn they were sharing
False,31+29=60
true,40+8=48
False,17-7=10
True,98-11=87
False,51-8=43
Use the Pythagorean Theorem:
a² + b² = c²
4² + b² = 8.5²
16 + b² = 72.25
b² = 56.25
b = 7.5
The ladder reaches a height of 7.5 ft on the wall
40 - 12 = 28
28 / 40 = 0.7
0.7 * 100 = 70%
The percentage decrease is 70%.
Answer:
6.13%
Step-by-step explanation:
We are given an investment of $8000 deposited for 4 years. We have to find the effective annual yield for which we will need the interest rate and the compounding period.
Annual interest rate compunded quarterly, r = 6% = 0.06
Compounding period is quarterly, n = 4
Annual EffectiveYield = 
= 0.0613
The annual effective yield is 6.13%
