D. 12

Answers

Answer 1
Answer:

The number of boxes of tiles is 6. The correct option is A.

What is the area of the circle?

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the circle in a two-dimensional plane is called as the area of the circle.

Given that a circular playground for a daycare centre is to be covered with square tiles that are 9 inches on each side. The circle has a diameter of 12 ft. The tiles are packaged in boxes of 25 tiles.

The area of the circle is,

A = π x r²

A = π x 6²

A = 113 square ft

The area in square inches is,

A = 113 x 12 = 1356 square inches

The number of tiles will be,

Number = 1356 / 9

Number = 150

The number of boxes,

N = 150 / 25
N = 6 boxes

Therefore, the number of boxes will be 6.

Antonio and Bendu want to earn money this summer by setting up a lemonade stand. Thinking about last summer's sales, they realize that they sold an average of 200 cups per day when they charged $1.00 per cup. Other vendors with similar sales have noted that for every $.25 increase in price, they sold 20 fewer cups. Using this information, what should they charge to maximize their income? And what is the function and plot points of this problem? GUYS PLEASE HELP ME OUT ON THIS IM DESPERATE AND USED 50 POINTS FOR THIS. AND DON'T TRY AND COPY AND PASTE THE QUESTION, BELIEVE ME, I'VE TRIED.

Answers

Answer:

1.) From the information given, they should charge $1.25 per cup to maximize their income

2.) Function y = -1.25x + 200

3.) (200, 200) and (180, 225)

Step-by-step explanation:

Let assume that they sold an average of 200 cups per day when they charged $1.00 per cup. Then they will realise $1.00 × 200 = $200 per day

If they increase the price by $ 0.25, they sold 20 fewer cups. That is, they will realise $1.25 × 180 = $225

Increase in profit = 225 - 200 = $25

From the information given above, they should charge $1.25 per cup to maximize their income

If income = y and number of cup = x

Slope = 25/-20 = - 1.25

Function y = -1.25x + 200

The plot point are:

(200, 200) and (180, 225)

Why is it not possible to draw a square that is not a parallelogram

Answers

So a square is a parallelogram with four sides of equal length and angles of equal size. In other words, all squares are parallelograms, but only some parallelograms are squares.
because just because they have 4 sides and equal length doesn't mean that all squares are parallelogram.
