Solve for h in the mathematical formula A=1/2(a+b)h
1 answer:
Step-by-step explanation:
Since we arent given enough information to SOLVE for h, I will get as close as I can by rearranging the equation for h
Convert the fraction to a decimal for simplicity
A = 0.5(a + b)h
Divide both sides of the equals by 0.5
A/0.5 = (a + b)h
We can convert A/0.5 into its reciprocal
2 A = (a + b)h
Divide both sides of the equation by the bracketed (a + b)
(2 A) / (a + b) = h

Answer:
see explanation
Step-by-step explanation:
Given
A = h(x + y)
Multiply both sides by 2 to eliminate the fraction
2A = h(x + y) ( divide both sides by h )
= x + y ( subtract x from both sides )
y = - x
Answer:
After 7.04 years the amount will reach $57,000 or more
Step-by-step explanation:
The rule of the compound interest is , where
- A is the new value
- P is the initial value
- r is the rate in decimal
- n is the period of the time
- t is the time
∵ A loan of $36,000 is made at 6.75% interest, compounded annually
∴ P = 36,000
∴ r = 6.75% = 6.75 ÷ 100 = 0.0675
∴ n = 1 ⇒ compounded annually
∵ The amount after t years will reach $57,000 or more
∴ A = 57,000
→ To find t substitute these values in the rule above
∵ 57,000 = 36,000
∴ 57,000 = 36,000
→ Divide both sides by 36,000
∵ =
→ Insert ㏒ in both sides
∴ ㏒( ) = ㏒
→ Remember ㏒ = n ㏒(
)
∵ ㏒( ) = <em>t</em> ㏒(1.0675)
→ Divide both sides by ㏒(1.0675)
∴ 7.035151337 = <em>t</em>
<em>∴ </em><em>t </em>≅ 7.04
∴ After 7.04 years the amount will reach $57,000 or more
