Answer:

A = 60

B = 30

Step-by-step explanation:

Complementary angles add to 90 degrees

A = 2B A is twice the measure of B

A + B =90 Complementary angles add to 90 degrees

Substitute the first equation in for the second

A+B =90

2B+B=90

Combine like terms

3B = 90

Divide by 3

3B/3 = 90/3

B = 30

A = 2B

A = 2*30

A = 60

A circle passes through the vertices of a square of side 20cm.Find the radius of the circle.

algol13

Answer:

14,1 cm

Step-by-step explanation:

If a circle passes through the vertices of a square then the diagonal of a square is a circle diameter.

We use Pytagoras Theorem to find out the length (L) of the diagonal given that:

L² = (20)² + (20)²

L² = 2* (20)²

L = √2 * 20

L = 1,4142* 20

L = 28,28 cm

L diagonal in the square is a diameter of the circle then radius of a circle is:

r = L/2 ⇒ r = 28,28 /2 ⇒ r = 14,14 cm

During her first year of college, Sara put $2000 in the bank to save for a trip to Italy after graduation. The money earned 3% s

vodomira [7]

Answer:

Sara will have US$ 2,251.02 in the bank after 4 years for her trip to Italy.

Step-by-step explanation:

1. Let's review the data given to us for solving the question:

Investment of Sara during her 1st year of college = US$ 2,000

Duration of the investment = 4 years

Annual interest rate = 3%

2. Let's find the future value of this investment after 4 years, using the following formula:

FV = PV * (1 + r) ⁿ

PV = Investment of Sara during her 1st year of college = US$ 2,000

number of periods (n) = 4

rate (r) = 3% = 0.03

Replacing with the real values, we have:

FV = 2,000 * (1 + 0.03) ⁴

FV = 2,000 * (1.03) ⁴

FV = 2,000 * 1.12550881

FV = 2,251.02

Sara will have US$ 2,251.02 in the bank after 4 years for her trip to Italy.
