It takes 7 hours to mow 4 lawns
Therefore every hour, (4 ÷ 7) or 4/7 lawns are mowed. This gives the rate.
For 35 hours, 4/7 x 35 lawns are mowed.
=35 ÷ 7 = 5
= 4 × 5
= 20 lawns
Any monomial without a written exponent has a degree of 1.
Answer:
30 feet
Step-by-step explanation:
A ratio of 4:3 means that if one part can be represented by x, the original height is equal to 4 * x and the mural height is equal to 3 * x. This is because the ratio of original : mural is 4 : 3, so if one part = x, we have 4 * x : 3 * x. Therefore,
original mast height = 40 feet
4 * x = original mast height = 40 feet
divide both sides by 4 to get x
x = 10 feet
3 * x = mural mast height = 3 * 10 feet = 30 feet

Answer:
$23,700
Step-by-step explanation:
The compound interest formula can be helpful for this. Fill in the given values and solve for the unknown.
FV = P(1 +r/n)^(nt)
where r is the annual interest rate, n is the number of times interest is compounded in a year, t is the number of years, P is the amount invested, and FV is the future value of that investment.
$27,000 = P(1 +0.022/365)^(365·6) = 1.1411037P
P ≈ $23,700
