What is a circle?

A circle is a two-dimensional figure with a radius and circumference of 2pir.

The area of a circle is πr².

We have,

The pier is in the shape of a semicircle.

So,

The area of a semicircle is half of the area of a circle with the same diameter.

The area of a circle with a diameter of 56m is:

A = πr² = π(28)² = 2463.23 m²

So,

The area of the semicircle is:

A/2 = 2463.23/2= 1231.62 m²

Therefore,

The area of the pier is approximately 1231.62 square meters.

.A bag contains 3 red checkers and 5 black checkers. A checker is selected, kept out of the bag, and then another checker is selected. What is the P(black, then red)?

Answers

Answer: 15 / 56

Step-by-step explanation:

Number of red checkers = 3

Number of black checkers = 5

Total number of checkers = 8

P(black, then red) = 5/8 × 3/7 = 15/56

We should note that the probability to pick a black checker first will be 5 out of 8. Then, there'll be 7 checkers left and the probability to pick a res checker will be 3/7. We then multiply the probabality of each together.

Answers

Answer:

$1000$600$250

Step-by-step explanation:

Let t represent the third-place prize value. Then the first place prize has a value of 2t+500, and the second-place prize is 2t+100. The total value of the three prizes is ...

  t +(2t+500) +(2t+100) = 1850

  5t +600 = 1850

  5t = 1250

  t = 250 . . . . . . . . . . . third place prize

  2t +500 = 1000 . . . . first place prize

  1000 -400 = 600 . . .second place prize

The prizes for 1st, 2nd, and 3rd places are $1000, $600, and $250, respectively.

Suppose a book has been on a desk 1 m above the floor. A student accidentally knocks the book off of the desk and it falls to the floor. During this process, ___________ energy has been changed into _______ energy.

Answers

Answer: Potential; Kinetic

Step-by-step explanation:

''...During this process, potential energy has been changed into kinetic energy.''

Potential energy is the energy that a stationery object has because it is stored within the object. In this case the object is the book.

When an object begins to move, it gains kinetic energy which is converted from its potential energy. As the book falls to the floor in this scenario, it gained kinetic energy as its potential energy was converted to enable it move.

How much annual income would you need to have if, using the 28/36 ratio, your maximum allowable recurring debt is $500? A. $21,430 b. $30,000 c. $62,500 d. $75,000

Answers

Answer: $75,000

Step-by-step explanation:

The 28/36 rule is that the maximum that the person is to spend on household expenses is 28% of their monthly income. 36% of their monthly income is the maximum they can spend on debt and their household expenses.

This means that the maximum they are allowed to spend on debt is:

= 36 - 28

= 8%

If their maximum allowable debt is $500, this is 8% of their gross income. This Gross monthly income is therefore:

500 = x * 8%

= 500/ 8%

= $‭6,250‬

Their gross annual income is:

= 6,250 * 12

= $75,000

$75,000

Find x and y with ray theorem

Answers

Answer:

x = 12 and y = 9

Step-by-step explanation:

Using the similarity theorem to fid the value of x and y

16/x = 16+6/16.5

16/x = 22/16.5

22x = 16*16.5

22x = 264

x = 264/22

x =12

Similarly

24/x = 24+y/16.5

24/12 = 24+y/16.5

2 = 24+y/16.5

24+y = 2 * 16.5

24+y = 33

y = 33-24

y = 9

Hence x = 12 and y = 9

Answer:

The first term is 5 and the common difference is 9-5=4, so the n-th term is ...

  an = a1 +d(n -1)

  an = 5 +4(n -1) = 4n +1

Then the term number for the term 129 is ...

  129 = 4n +1 . . . . . put the given value in the formula

A furniture store pays a wholesale price for a mattress.
Then, the store marks up the retail price to 150% of the
wholesale price. Later, they put the mattress on sale for
50% off of the retail price. A customer just bought the
mattress on sale and paid $1,200.
a. What was the retail price of the mattress, before the
discount?

Answers

Answer:

Step-by-step explanation:

Part A:

Given that the mattress is sold for 50% off of the retail price, let the retail price of the mattress be x, then

50% of x = 1200

⇒ 0.5x = 1200

⇒ x = 1200 / 0.5 = 2400

Therefore, the retail price of the mattress, before the discount is $2,400.

Part B:

Given that the store marks up the retail price to 150% of the wholesale price. Let the whole sale price be p, then

(100% + 150%) of p = 2400

250% of p = 2400

2.5p = 2400

p = 2400 / 2.5 = 960.

Therefore, the wholesale price, before the markup was $960

a) x = 20°

b) x = 70°

c) x = 50°

Step-by-step explanation:

a) 2x + 3x + 4x = 180°

9x = 180°

x = 50°

b) (x - 20°) + (x - 20°) + (x + 10°) = 180°

3x - 30° = 180°

3x = 210°

x = 70°

c) (x + 10°) + (x + 20°) + x = 180°

3x + 30° = 180°

3x = 150°

x = 50°

8. Identify the x and y intercept of the equation:
12x - 8y = 48

Answers

Answer:

X- intercept(S) : (4,0)

Y- Intercept(S) : (0, -6)

Step-by-step explanation:

To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for Y.

Hopes this helps!

The x- intercept (4, 0) and y intercept ( 0, -6).

What is Intercept?

The points where a line crosses an axis are known as the x-intercept and the y-intercept, respectively.

when the independent variable is 0 and you want to know the value of the dependent variable (zero).

Given:

Equation: 12x - 8y = 48

Now, for x- intercept put y= 0

12x - 8(0)= 48

12x= 48

x= 4

and, for y- intercept put x= 0

12(0) - 8y= 48

-8y= 48

y= -6

Hence, the x- intercept (4, 0) and y intercept ( 0, -6).
