Are there any answer choice?
Answer:
total = 1600 +0.05x
Step-by-step explanation:
I = Prt
You want the sum of the interest from the two investments. The interest at 13% is ...
I = Prt = x(0.13)(1) = 0.13x
The interest at 8% is ...
I = Prt = (20000-x)(0.08) = 1600 -0.08x
Then the total interest earned is ...
total = 0.13x + (1600 -0.08x)
total = 1600 +0.05x
The correct answer is x = -90.
To find this, solve using the order of operations. See the example below.
x/-3 - 41 = -11 ----> Add 41 to both sides
x/-3 = 30 ----> Multiply each side by -3
x = -90
Answer: h = (S - 2πr²) / 2πr
Step-by-step explanation:
Since we are given that
S = 2πrh + 2πr²
Subtracting by 2πr² on both sides we get
S - 2πr² = 2πrh
Dividing by 2πr on both sides we get
(S - 2πr²) / 2πr = h
So
The final equation is
h = (S - 2πr²) / 2πr
