Answer:

6

3/5

Step-by-step explanation:

The total of all books is 1.

For Fiction to be 3 times more than Biographies.

Biographies have to have same probability to be chosen as poetry.

So to solve for the probability to choose Fiction is 3 × 1/5 = 3/5

The number of fiction books is solved with 10 × 3/5 = 6

Answer:

17

Step-by-step explanation:

c = a^2 + b^2 = 15^2 + 8^2 = 17

Answer:

The only graph whose line is strait

Step-by-step explanation:

This graph represents the situation because energy bills will have a set amount of money which directly correlates with the amount of energy you use. When it gets cold you use more energy to keep you warm. As you use more energy your price rises at the same pace-thus a strait line.

Answer: A) The relationship is proportional because the ratio of m to k is constant.

______________________________________________________

Step-by-step explanation:

17.699 ÷ 11 = 1.609

41.834 ÷ 26 = 1.609

&

54.706 ÷ 34 = 1.609

______________________________________________________

The three equations above equal 1.609 making the relationship between m & k constant.

If you were to plot these coordinates on a graph you would see a straight line.

Answer:

Step-by-step explanation:

a) Let the width = w

Two times its width = 2*w = 2w

9 inches less than 2w = 2w - 9

Length = 2w - 9

Area of rectangle = length *width = 180 square inches

(2w - 9 ) * w = 180

2w*w - 9*w = 180

2w² - 9w - 180 = 0

b) sum = -9

Product= -360

Factors  = -24 , 15    {15 *[-24] = -360 and 15 + (-24) = -9 }

2w² - 9w - 180 = 0

2w² - 24w + 15w - 180 = 0

2w(w - 12w) + 15(w - 12) = 0

(w -12) (2w + 15) = 0

{Ignore 2w + 15 = 0 as measurements cannot be a -ve value}

w - 12 = 0

w = 12 inches

l = 2w -9

 = 2*12 - 9

= 24 - 9

l = 15

length = 15 inches

Width = 12 inches

c) Perimeter = 2 *(length + width)

                     = 2*(15 + 12)

                     = 2 * 27

                     = 54  inches

Answer:

Answer:

1. 108.375 2. 76.765625

Step-by-step explanation:

1. We have the s-value now, which is 4.25.

Plug it in to the equation for surface area:

6*(4.25)^2

6*4.25*4.25

Using a calculator, we get 108.375

2. Plug 4.25 in to the equation for volume:

(4.25)^3

4.25*4.25*4.25

Using a calculator, we get 76.765625

Answer: 52

Step-by-step explanation: 75 - 23 = 52, therefore, x = 52

Answer:

Yes

Step-by-step explanation:

For example, 7/4 x 2/3=14/12=7/6. 7/6>1.

Answer:

It matters on the fraction! for example:

the answer is C because if we get rid of 12 it will have no effect on the mode and it will not change mode. the mode will remain the same.

if I helped mark me the brainest!!

Answer:

D

Step-by-step explanation:

D. because 48 is much bigger than the other numbers and 12 isn't that much smaller that 19 that 48 is bigger than 35 and because there is only one 48 it won't affect the mode

The mode is 19 or/and 22

Answer:

Is it c

Answer:

14 + j = 28

Step-by-step explanation:

I hope this helps :)

Answer:

Step-by-step explanation:

You could do negative numbers because no positive number is less than 0, as you know.

So, it would have to be a negative one because they are to the left of zero on a number line, meaning less than. A positive number on a number line is usually to the right of zero, meaning more than.

For instance, x could equal -1 and y could equal -4.

It would be in Quadrant 3.

Hope this helps! :)

Is Brainliest an option?

Answer:

Hi, there your answer will be y=2x-4

Step-by-step explanation:

Well finding the y-intercept you have to see what goes through the y-axis in this case it is -4

To find the slope you can do [tex]\frac{rise}{run}[/tex]

or you can use the slope formula which is

[tex]\frac{y2-y1}{x2-x1}[/tex]

In this case, I'll be using the slope formula I'll pick two coordinate which are (0,-4) and (3,2). I'll be plugging that in

[tex]\frac{2-(-4)}{3-0}[/tex]=[tex]\frac{6}{3}[/tex]

We will simplify [tex]\frac{6}{3}[/tex] which will equal to 2

Hope this helps :)

Answer:

points at (2,6) (3,9) (7,21) (8,24)

Step-by-step explanation:

Answer:

..

Step-by-step explanation:

each line is 1, so in between 0 and 5, the numbers 1-4 are there.

Coordinate place (x,y), the x is the horizontal or just the one going left and right. Y places are the numbers going up and down.

Take (2,6), we go to the origin (0,0) and we go 2 to the right since its in the x place, then we go from the point where we moved and go up 6 since its a y.  

does that make sense?
