Step-by-step explanation:

Answer:

35%

Step-by-step explanation:

52/80=0.65

0.65x100=65

65% is the percent that she has read.

100%-65%= 35%

She has not read 35% of the pages.

Answer:

She hasn't read 35% of the book

Step-by-step explanation:

1st way: Since 80 pages represent 100%

52 pages represent 100 * 52 / 80 = 65% pages read

100 - 65 = 35 pages page not read.

2nd way: 80 - 52 = 28 pages not read

28 pages represent 100 * 28 / 80 = 35% pages not read

Answer:

undefined

Step-by-step explanation:

Vertical lines never have a defined slope as you can never divide a number by zero

The equation of a line in standard form is:

y

=

m

x

+

b

Where

m

is our slope

b

is our y-intercept

In our case we are only given

x

=

6

x

=

6

is a vertical line therefore the slope is undefined.

Answer:

perimeter = 36

Step-by-step explanation:

Each diagonal side is the hypotenuse of a right triangle with legs of lengths 6 and 8.

c² = a² + b²

c² = 6² + 8²

c² = 36 + 64

c² = 100

c = √100

c = 10

Each horizontal side measures 8.

perimeter = 8 + 8 + 10 + 10

perimeter = 36

Answer:

3.49 ft

Step-by-step explanation:

y = 0.125x

y = –16x^2 + 56x

Set the equations equal since the height of the hill

and the height of the ball must be the same

–16x^2 + 56x = 0.125x

Subtract 0.125x from both sides

–16x^2 + 55.875x = 0

Factor out x

x(–16x + 55.875) = 0

From the zero product rule

x = 0

and

–16x + 55.875 = 0

–16x = –55.875

Divide both sides by –16

x = 3.4921875

Diiference in height

3.4921875 - 0 = 3.4921875

3.49 ft

[tex]y = -\frac{1}{2}x - 1[/tex]

Step-by-step explanation:

Let's pick two points on the line: [tex]P_1(-4, 1)[/tex] and [tex]P_2(2, -2).[/tex] Let's calculate the slope of this line using these points:

[tex]m = \dfrac{y_2 - y_1}{x_2 - x_1} = \dfrac{-2 - 1}{2 - (-4)} = -\dfrac{1}{2}[/tex]

With this value of the slope, we can write the general slope-intercept form of the equation as

[tex]y = -\frac{1}{2}x + b[/tex]

To solve for the y-intercept b, let's use either P1 or P2. I'm going to use P2:

[tex]-2 = -\frac{1}{2}(2) + b \Rightarrow b = -1[/tex]

Therefore, the slope-intercept form of the equation is

[tex]y = -\frac{1}{2}x - 1[/tex]

30 Chocolates

The box was new and therefore full, so it had 5/5 of chocolates left.

When Bob ate 18, 2/5 were left, so he must have eaten 5/5 - 2/5 or 3/5 of the chocolates:

5/5 - 2/5 = 3/5

You know that 3/5 of the chocolates are 18, as he ate 18 chocolates. Divide 18 by 3 to get 6:

18 / 3 = 6

This is 1/5 of the chocolates. Multiply this by 5 to get 30:

6 * 5 = 30

This is 5/5 of the chocolates and therefore the total is 30 chocolates.

Answer:

Is ka answers D ha.........

Answer:

The answer is D.

Step-by-step explanation:

(8 ,33) = ([tex]x_{1} , y_{1} )[/tex]

m = 3

To find the equation, use the formula:

y - [tex]y_{1}[/tex] = m(x - [tex]x_{1}[/tex])

Put the values in the equation

y - 33 = 3(x - 8)

y - 33 = 3x - 24

Now to get only the y, put the [tex]y_{1}[/tex]

y - 33 = 3x - 24

    33           33

------------------------

   y    =  3x + 9
