Find the probability that a point choseb at randon the figure will lie in the shaded region. Write your anser as a percentage rounding to the nearest hundreth in percentage form

Answers

Answer 1

Answer: 21.46%

=======================================================

Explanation:

Let's find the area of one of the circles

A = pi*r^2

A = pi*10^2

A = 100pi

One circle is exactly 100pi square meters in area.

Four of the circles then combine to a total area of 4*100pi = 400pi square meters.

The distance along the bottom of the square is equal to two diameters, each diameter being 2r = 2*10 = 20 meters. So the distance along the bottom of the square is 2*20 = 40 meters. The square has an area of 40^2 = 1600 square meters.

The shaded region would therefore have an exact area of 1600-400pi square meters.

This approximates to 1600-400pi = 343.362938564082

Divide this over the area of the square to get the probability we want to find:

343.362938564082/1600 = 0.21460183660256

That's roughly 0.2146, which converts to 21.46%

Answer 2

Answer:

21.5%

Step-by-step explanation:

Find the area of the square, which is 40² or 1600 sq m

Find the area of one circle, multiply it by 4, then subtract that from 1600

A = 100(3.14) = 314

314 x 4 = 1256

1600 - 1256 = 344

Probability of landing in the shaded region is 344/1600 = 21.5%

Erica bought a road bike using the
store's payment plan. She made a
$320 down payment and makes
monthly payments of $91. If the total
cost is $1,867, how many months will
Erica be paying for the bike? Write and
solve an equation.

Answers

Answer:

17 months i think

Step-by-step explanation:

1867$-320$=1547

1547:91=17

The number of months Erica will be paying for the bike, if She made a $320 down payment and makes monthly payments of $91 is 17 months.

What is the equation?

A formula known as an equation uses the equals sign to denote the equality of two expressions. It appears to be a mathematical expression on the left, an equal sign in the center, and a mathematical expression on the right.

Given:

The down payment = $320,

The amount of monthly installment = $91,

The total cost = $1867

Calculate the remaining amount after the down payment as shown below,

The remaining amount = The total cost - The down payment

The remaining amount = 1867 - 320

The remaining amount = $1547

Calculate the number of months as shown below,

The number of months = The remaining amount / The amount of monthly installment

The number of months = 1547 / 91

The number of months = 17 months

Step-by-step explanation:

By Using Pythagorean Triplet we can say that

61 in, 60 in, 11 in. represents three sides of a right triangle

FOR VERIFICATION ONLY:

(11)² + (60)² = (61)²

121 + 3600 = 3721

3721 = 3721

Thus, 3721 = 3721 represents three sides of a right triangle

Answers

Answer:

x = 2, y = 0

Step-by-step explanation:

find y in terms of x:

8x - 4y = 16

4y = 8x - 16

y = 2x - 4

substitute y:

8x + 4y = 16

8x + 4(2x - 4) = 16

8x + 8x - 16 = 16

16x = 32

x = 2

find y:

8x + 4y = 16

16 + 4y = 16

y = 0
