Answer:
option a
Step-by-step explanation:
y^7/8 / y^1/4
First we will accommodate the fractions
1/4 = 2/8
y^7/8 / y^2/8
Then we will subtract the exponents of the powers since they have the same base and are dividing
7/8 - 2/8 = 5/8
y^5/8
Finally we pass the 8 as radical root
8√y^5

Step-by-step explanation:
Formulae for simple interest is;
A= P (1 + rt) Whereby;
A = Total Accrued Amount (principal + interest)
P = Principal Amount
I = Interest Amount
r = Rate of Interest per year in decimal; r = R/100
R = Rate of Interest per year as a percent; R = r * 100
t = Time Period involved in months or years
15300 = 3200 (1 + 106.5/100 *t)
15300/3200 = 1 + 1.065t
4.78125 – 1 = 1.065t
3.78125 = 1.065t
3.78125/1.065 = t
3.55 = t
Rounded off to the nearest whole number;
= 4
Answer:
60°
Step-by-step explanation:
90+30=120°
180-120=60°
If the boat initially cost $11850 and INCREASED in value by 10% per year, we'd calculate the final value like this:
V = $11850(1+0.10)^8
But if the boat is losing value (depreciating) over time, we'd calculate its final value like this:
V = $11850(1-0.10)^8 = $11850(0.90)^8 = $11850(0.4305) = $5101.04 (answer)
