Answer:
A. 2827 square cm
Step-by-step explanation:
Diameter of circle = 60 cm
Therefore, radius = 60/2 = 30 cm
Well if you notice, 48, x, and x are all on the same line, so they must add up to equal 180 degrees. So...
2x + 48 = 180
2x = 132
x = 66
So each x is equal to 66 degrees. Now we know the triangle is a right triangle, and the sum of all interior angles must be equal to 180 degrees for a triangle. So...
66 + 90 + z = 180
156 + z = 180
z = 24
Z equals 24 degrees! I hope this helps!
Answer:
$20,850.00)
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year.
Solving our equation:
A = 139000(1 + (0.05 × 3)) = 159850
A = $159,850.00
The total amount accrued, principal plus interest, from simple interest on a principal of $139,000.00 at a rate of 5% per year for 3 years is $159,850.00.
