Answer:
43.2 grams
Step-by-step explanation:
A = P (1 + r)^t
where A is the final amount,
P is the initial amount,
r is the rate of growth or decay,
and t is time.
Given:
P = 570
r = -0.18
t = 13
A = 570 (1 − 0.18)^13
A = 43.2
Since the discount is 15%, that means that they will pay 85% of the original price ( 100% - 15% = 85%).
Multiply the original price by 85% to find the discounted price:
98.00 x 0.85 = 83.30
They will pay $83.30 for the saw.
Let h represent the height of the building. Then the difference between the two angle measurement locations is
.. h/tan(39°) -h/tan(50°) = 300 ft
.. h = (300 ft)/(1/tan(39°) -1/tan(50°))
.. h ≈ 758 ft
The height of the building is about 758 feet.
3/8 divided by 5/8 = 3/5
hope this helps :D
So where's the rest of the question?
