aev [14]

Answer:

52.4 cm

Step-by-step explanation:

Circumference of a circle = 2πr

Radius, r = diameter / 2

= 17 cm / 2

= 8.5 cm

π = 3.14

Circumference of a circle = 2πr

= 2 × 3.14 × 8.5

= 53.38 cm

Approximately 52.4 cm

RSB [31]

The amount of the lump sum that the insurance company must put into a bank account is $6,928,571.43 option (B) is correct.

<h3>What is the percentage?</h3>

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

We have:

Gertrude has a life insurance policy that will pay her family $97,000 per year.

If interest rates are at 1.4% when the insurance company has to pay

r = 1.4%

or

r = 0.014

The amount of the lump sum that the insurance company must put into a bank account:

= 97,000/0.014

= 6928571.429 ≈ $6,928,571.43

Thus, the amount of the lump sum that the insurance company must put into a bank account is $6,928,571.43 option (B) is correct.

One angle of a linear pair is 10 more than two-thirds the other angle. Find the measure of both angles.
nata0808 [166]

Answer:

102° and 78°

Step-by-step explanation:

let one angle be x then the other angle is

\frac{2}{3} x + 10 ( 10 more than two-thirds the other angle )

A linear pair of angles sum to 180°, hence

x + \frac{2}{3} x + 10 = 180

\frac{5}{3} x + 10 = 180 ( subtract 10 from both sides )

\frac{5}{3} x = 170

multiply both sides by 3 and divide by 5

5x = 510

x = 102

The 2 angles are x = 102° and

\frac{2}{3} x + 10 = \frac{2}{3} × 102 + 10 = 68 + 10 = 78°

As a check : 102 + 78 = 180 → correct
