A triangle is inside a circle where the triangle's base is on the circle's diameter as shown. What is the area of the shaded reg

mr Goodwill [35]

I think the shaded region for this problem will the part of the circle that is not covered by the triangle. First, determine the area of the circle by the equation,
A = πD²/4
Substituting the given diameter,
A = π(16 ft)²/4 = 200.96 ft²
Then, determine the area of the triangle with the equation,
A = bh/2
Since the base of the triangle is the diameter, b = 16 ft. Then, its height will be half the height and that will be equal to 8 ft. Substituting,
A = (16 ft)(8 ft) / 2 = 64 ft²
The difference between the two areas is 136.96 ft².

Devon made a scale drawing of a triangle. He used a scale factor of 1/4 to draw the new triangle. How does each side of the new

Charra [1.4K]

The answer is Option A.
Scale Factors
If the Scale Factor IS 1, the polygon stays the SAME.
(If an equilateral triangle has a side length of 8 and the scale factor is 1, the sides will stay at 8)
If the Scale Factor is MORE THAN 1, the polygon's sides INCREASE depending on what the scale factor is.
(If a square has a side length of 3 and the scale factor is 4, the sides will increase to 12)
If the Scale Factor is LESS THAN 1, the polygon's sides DECREASE depending on what the scale factor is.
(If a square has a side length of 5 and the scale factor is 1/2, the side lengths will decrease down to 0.5)
Therefore each side length of the new triangle is 4 times shorter than the original (Option A)

1.)If The simple interest on $1,000 for 2 years is $160, then what is the interest rate?

VARVARA [1.3K]

Answer:

Please see the detailed answer below:

Step-by-step explanation:

1.)

Interest Rate = Interest / (Principal x Time)

Interest Rate = $160 / ($1,000 x 2)

Interest Rate = $160 / $2,000

Interest Rate = 0.08

Interest Rate = 8%

2.)

Interest in 20 Years

Interest = Interest Rate x Principal x time

Interest = 0.09 x $2,000 x 20

Interest = $3,600

Account Balance after 20 Years

Account Balance = Principal + Interest

Account Balance = $2,000 + $3,600

Account Balance = $5,600

Interest in 30 Years

Interest = Interest Rate x Principal x time

Interest = 0.09 x $2,000 x 30

Interest = $5,400

Account Balance after 30 Years

Account Balance = Principal + Interest

Account Balance = $2,000 + $5,400

Account Balance = $7,400

3.)

Interest = Interest Rate x Principal x time

Interest = 0.03 x $7,000 x 3

Interest = $630

Account Balance after 3 Years

Account Balance = Principal + Interest

Account Balance = $7,000 + $630

Account Balance = $7,630
