Hello!
Unit rates can be written as ratios. In this case, we have 4 bushels in one hour, or 4:1. In eight hours, we can multiply like a fraction, multiplying both by eight to get eight hours.
Our final answer is B) 8·4.
I hope this helps!
Rewrite s = 4 + sqrt(s+2) as s-4 = sqrt(s+2)
Square both sides: s^2 - 8s + 16 = s + 2
combine like terms: s^2 - 9s + 14 = 0
Factor this: (s-7)(s-2)=0
Solve for s: s={7, 2}
Answer:
$2388.95
Step-by-step explanation:
- Principal, P= $2250
- Annual Interest Rate, r= 3% =0.03
- Time, n= 2 years
- Since it is compounded monthly, Period, k= 12 Months
The worth of a compound deposit after a period of n years is calculated using the formula:
At maturity, the deposit will be worth $2388.95.
A direct variation is a linear equation. It describes a simple relationship between two variables.
Example: if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3.
Hope this helped!! :)
