Which phrase represents the graph below?

marissa [1.9K]

I would say neither of the above.

A is incorrect because in the graph, the curves get shorter over time, and if you were riding the same Ferris wheel, the curves would be the same size the whole time, because the Ferris Wheel would stay the same shape and height.

B is incorrect because the height increases then decreases and increases and decreases, etc, while the description is simply, a descending paper plane.

C is incorrect because it wouldn't be both of the above since they were both wrong.

Mr. Dieter wants to tile the family room in his basement. He has selected a pattern of square tiles that measure 9 inches by 9 i

RUDIKE [14]

Answer:

146 ft²

21.6 tiles

1.8 boxes

Step-by-step explanation:

Please find attached an image of the family room used in answering this question

the family room has the following shapes : 2 triangles and one rectangle

the area of the family room can be determined by calculating the area of each of the shape and adding the 3 areas together

area of a rectangle = length x breadth

16 x 7 = 112 ft²

Area of a triangle = 1/2 x base x height

Area of the smaller triangle = (1/2) x 4 x 3 = 6 ft²

Area of the bigger triangle = (1/2) x 8 x 7 = 28 ft²

Sum of the areas = 112 + 6 + 28 = 146 ft²

b.

1. First convert the area of the room to inches

1 ft = 12 in

146 x 12 = 1752 in²

2. the next step is to determine the area of the tile

area of a square = length²

9² = 81 in²

3. Divide the area of the room by the area of the tile

1752 / 81 = 21.6 tiles

c. total number of boxes that would be bought = 21.6 /12 = 1.8 boxes

Solve for the rate in the eqution d=rt

Zolol [24]

Answer:

The rate of the equation is r when r is a constant

Step-by-step explanation:

We need to solve for the rate of the equation

d = rt

Differentiating on both sides with respect to time

$\frac{\mathrm{d} d}{\mathrm{d} t}$ = $\frac{\mathrm{d} rt}{\mathrm{d} t}$

Considering r as a constant

$\frac{\mathrm{d} d}{\mathrm{d} t}$ = r× $\frac{\mathrm{d} t}{\mathrm{d} t}$

where, $\frac{\mathrm{d} t}{\mathrm{d} t}$ = 1

$\frac{\mathrm{d} d}{\mathrm{d} t}$ = r

The rate of the equation is r when r is a constant

The denominator of a rational number is greater than the numerator by 6 if the numerator and denominator are both increased by 2

DerKrebs [107]

Answer:

7/13

Step-by-step explanation:

Let's call x= numerator

We know that :

Denominator= x+6

And

(numerator +2)/(denominator +2) = 3/5

So

(x+2)/(x+6+2)=3/5

(x+2)/(x+8)=3/5

(x+2)*5=(x+8)*3

5x+10=3x+24

2x=14

x=7

In the end

Numerator= x =7

Denominator=x+6 = 13

So the original number is 7/13

I hope this helps, have a beautiful day
