Step-by-step explanation:

The inscribed angle R is half of the central angle O that subtends the same arc on the circle.

m∠O = 2(50°) = 100°

Thepotemich [5.8K]

If seven friends eat out and split a bill, we must first figure out how much each person would pay individually. To find this number, we need to divide the total bill by the total number of people. $100. 10/7 = 14.3, so each person payed $14.3 individually. If three friends only brought cash so they pay Henry to pay for their portion on credit card, then Henry would pay for those three friends and himself on a credit card, or just 4 times how much one of them payed. Since each of them payed 14.3, then to find out how much Henry payed on credit card, we need to multiply 14.3 by 4 which gives us our answer of $57. 12

Answer:

9.41%

Step-by-step explanation:

Data provided in the question:

Present value of the debt = $400

Interest = $454 million = $454,000,000

Time, n = 155 years

Now,

Future value = Present value of the debt + Interest

Future value = $400 + $454,000,000

Future value = $454,000,400

Also,

Using the compounding formula,

Future value = Present value × ( 1 + r )ⁿ

here,

r is the interest rate

Thus,

$454,000,400 = $400 × ( 1 + r )¹⁵⁵

( 1 + r )¹⁵⁵ = $454,000,400 ÷ $400

( 1 + r )¹⁵⁵ = 1,135,001

1 + r = 1.0941

r = 1.0941 - 1

r = 0.0941

r = 0.0941 × 100% = 9.41%
