Answer:

The number of pages in each book varies more last summer than this summer

Answer:

7.5 hrs.

Step-by-step explanation:

First we need to find how much Magan earns per hour using the slope-intercept form: y = mx + b

Slope (m) = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

We will be using: (4, 70.80) and (9, 159.30) to find the slope of this table..

[tex]m=\frac{y_2-y_1}{x_2-x_1} \\\\m=\frac{159.30-70.80}{9-4} \\\\m=\frac{88.50}{5} \\\\m=17.7[/tex]

y = mx + b

y = 17.7x + b

I will be using (4, 70.80) to find the value of b

(4, 70.80)

y = 17.7x + b

70.80 = 17.7(4) + b

70.80 = 70.80 + b

-70.80  -70.80

0 = b

y = 17.7x + b ==> y = 17.7x + 0 =  OR  y = 17.7x (since the value of b is 0)

The question wants us to find out how long it took Magan to make $132.75

y = 17.7x

132.75 = 17.7x

/17.7        /17.7

7.5 = x

This means that it took him 7.5 (seven and a half) hours to make $132.72

Answer:

7.5 hrs.

Hope this helps! Good luck! :)

Answer: x=-2

Step-by-step explanation:

Answer:

You can put the dollars on the y axis and the hours on the x axis. Whenever the hours increase by 1, move over 1 on the x axis and 7.50 up on the y axis.

The first point should be (1, $7.50).

                                        ↑      ↑

                                    hours, money earned

The second point then will be (2, $15.00), the third will be (3, $22.50), and so on.

Answer:

The surface area of the cylinder is about 439.823 m^2, so rounded to the nearest square meter would equal about 440 m^2.

Answer:

that is 6/14, which is 3/7 when simplified.

Step-by-step explanation:

Change 2 into a fraction (2/1)

To divide by a fraction, multiply by its reciprocal (6/7x1/2)

That equals 6/14

Simplify to 3/7

Answer :D

[tex]\frac{3}{7}[/tex] (3/7)

Question explanation:

[tex]\frac{6}{7}[/tex]÷ [tex]\frac{2}{1}[/tex]= 6 x 1 = [tex]\frac{6}{14}[/tex] = (simplifying) = [tex]\frac{3}{7}[/tex]

       (7 x 2)

Answer:

42

Step-by-step explanation:

Let the number be y

178% = 178/100

178% of y = 74.76

178/100 x y = 74.76

178y = 74.76 x 100

y = 7476/178

y = 42

Answer:

40°

Step-by-step explanation:

angle on a straight line = 180°

therefore

140+ m<BAC = 180°

m<BAC = 40°

Answer:

the angle BAC is 40 degrees

Answer:

The median of the first is larger than the median of the second by 12.5

Step-by-step explanation:

A box and whisker plot shows the median by using a line inside the box. Wherever the line is is the median or middle value in an ascending list. Chapter 9 is in between 75 and 80, which would be 77.5, and chapter 10 is aligned with 65, which means that 77.5-65 is 12.5 and the median for chapter 9 is greater than the median of chapter 10 by 12.5.

Answer:

Step-by-step explanation:

(10-6)/(0-24)

=4/(-24)

=0.166

Answer:

14

Step-by-step explanation:

Because the median is the middle number when the data set is in order least to greatest so you already have it in least to greatest so thank you for helping me.

and for extra just in case.

Mean=16.222

the mean= the average of the data set

Mode is 13,14

The mode is the number that appears the most in a data set and 13 and 14 appear twice.

Your range is=13

Range is the highest number subtracting the lowest number so 24 -11 which =13

Minimum is 11 because the minimum is the lowest number in data set..

Maximum is 24

Maximum is the highest number in the data set.

I hope this helps have a awesome day:)

The median of the provided data set is 14, as the middle value of this data set arranged in increasing order is 14.

The median of the data set is the middle value of the data when data is arranged in the increasing or decreasing order.

The given data set in the problem is,

Answer:

24 cm²

easy way to find surface area of a cube.

use the formula: 6a²

[tex]\hookrightarrow 6(2)^2[/tex]

[tex]\hookrightarrow 6(4)[/tex]

[tex]\hookrightarrow24[/tex]

We know that:

[tex]\space\ Surface \space\ area \space\ of \space\ cube=\s Area \space\ of \space\ it's \space\ faces[/tex]

This means that:

[tex]\space\ Surface \space\ area = [(2)(2)] + [(2)(2)] + [(2)(2)] + [(2)(2)] + [(2)(2)] + [(2)(2)][/tex]

Simplify the expression to find the surface area.

Simplifying the expression:

[tex][(2)(2)] + [(2)(2)] + [(2)(2)] + [(2)(2)] + [(2)(2)] + [(2)(2)] \\\\\ [4] + [4] + [4] + [4] + [4] + [4]\\\\ 4[6] \\\\ 24 \space\ cm^{2}[/tex]

Hence, the surface area is 24 cm².

Answer:

=> The third side of the triangle is √53 mm

Step-by-step explanation:

We know that this is a right angled triangle ,

so , by using Pythagoras theorem we can find out the third side of the triangle ,

=> P²+B²= H²

=> 7²+2² = H²

=> 49+4 = H²

=> 53 = H²

=> √53 = H

The third side of the triangle is √53mm
