Answer:
145⁰
Step-by-step explanation:
180 minus 73⁰ plus 62⁰
which is 180 minus 135
145⁰
3 packs of pencils ( 30 pencils)
5 packs of erasers (30 erasers)
Answer:
B. 4 3/8
Step-by-step explanation:
7/8 X 5 = 4 3/8
We have the formula A = (h x b) / 2, where A is the area of the triangle, h is the height of the triangle, b is the base of the triangle;
So, 32 =(8 x b) / 2;
Then, 64 = 8 x b;
b = 64 ÷ 8;
b = 8 inches;
The value of t that makes the factor e^(.032t) have the value of 2 can be found using logarithms.
2 = e^(0.032t)
ln(2) = ln(e^(0.032t)) = 0.032t
t = ln(2)/0.032 ≈ 21.66
It would take 21.66 years for the cost to double.
