Answer:
The amount of fabric she needs is 3/4 yards
Step-by-step explanation:
To calculate the amount of fabric needed, we need to subtract the sum of what she has at school and at home from what she needs.
What she has can be calculated by adding 3 1/4 + 1 1/2
This would be easier in terms of decimals.
3 1/4 = 3.25 (1/4 = 0.25)
while 1 1/2 = 1.5(1/2 = 0.5)
Adding both, we have 3.25 + 1.5 = 4.75 yards
What is needed is 5 1/2 yards = 5.5 yards
What is needed more is thus 5.5 yards - 4.75 yards = 0.75 yards
Mathematically 0.75 in decimals = 3/4 in fraction form
Answer: 1000 hours.
Step-by-step explanation: To travel 9 x 10^8 feet, it would take (9 x 10^8)/15000 minutes. This equals 60000 minutes. We divide this number by 60 to convert to hours. This equals 1000 hours.

Answer:
a. 0.81
b. v = 28000(0.81^n)
c. 2757.36
Step-by-step explanation:
a. The growth factor is 1 more than the growth rate. Here, the growth rate is -19% (per year), so the growth factor, the multiplier, is ...
1 -0.19 = 0.81
__
b. The equation sets value equal to the original value multiplied by the growth factor to the power of the number of years:
value = (original value) × (growth factor)^n
v = 28000(0.81^n)
__
c. For n=11, this is ...
v = 28000(0.81^11) ≈ 2757.36
The value of the truck after 11 years is about $2757.
