Answer:
(6+8)/2 = 7
Step-by-step explanation:
Answer:
They are adjacent.
Step-by-step explanation:
2x + 4x = 90°
6x = 90°
therefore x = 90°/6 = 15°
6 and 3
6 and 3. 6x5=30 and 3x10=30
For every hour she works, her earnings go up by $10.
First we will find the interest on:
P = $235 principal
t = 2 years
r = 0.1415 annual rate
A = future value
I = A - P the interest
A = P(1 + r)^t
A = 235(1 + 0.1415)^2
A = $306.21
I = A - P
I = $306.21 - $235
I = $71.21
the interest was $71.21.
Next lets find the lifetime cost value:
Lifetime cost value = 306.21 + 5*1.56*52 + 5*0.78*52 = $914.61 (considering that 1 year = 52 weeks)
Now lets find the percentage what percentage the interest is of the lifetime cost:
(71.21/914.61)*100 = 7.79%
