Answer:
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1+r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
A = $235,000
P = $53,000
n = 1 because it was compounded once in a year.
t = 18 years
Therefore,.
235000 = 53000(1 + r/1)^1 × 18
235000/53000 = (1 + r)^18
4.43 = (1 + r)^18
Raising both sides to the power of 1/18, it becomes
4.43^(1/18) = (1 + r)^18 × 1/18
1.086 = 1 + r
r = 1.086 - 1
r = 0.086
r = 0.086 × 100 = 8.6%
The answers is the picture I posted. I did in khan academy and it was right.
Given: 5x – 4 + 13x = 5
Combine like terms in the given expression.
⇒ (5x + 13x) – 4 = 5
⇒ 18x – 4 = 5
By addition property of equality, add 4 on both sides to equal to the expression.
⇒ 18x – 4 + 4 = 5 + 4
⇒ 18x = 9
By division property of equality, divide 18 on both sides to equal the expression.
⇒ 
By symmetric property of equality, both sides are equal
⇒ 
Hence, .
Answer: NOT a right triangle
<u>Step-by-step explanation:</u>
If it is a right triangle, the sum of the squares of the shorter sides must equal the square of the larger side.
7² + 8² = 14²
49 + 64 = 196
113 = 196 FALSE!
These side lengths do not form a right triangle.
Answer: x=18
First cross multiply 4/3=24/x to get 4x= 3*24
Then simplify: 4x=72; x=18
