Stephen can deliver 16 newspapers in 20 minutes. How long will it take him to deliver 64 papers? How long will it take to deliver 140 papers? How many papers can you deliver in 195 minutes?

Step-by-step explanation:

y directly proportional to X

y=kx

when k is constant

y is 25 and X is 120

25=k120

divide both sides by 120

25/120

k=25/120

there fore the law connecting is 25/120

what is the value of y when x = 72? 25/120*72=3

therefore y is 3

Answer:

B and D

Step-by-step explanation:

Using the slope, it is found that the correct option is:

No, the contractor does not believe the roof is steep because the slope is 0.

Given two points, [tex](x_0, y_0)[/tex] and [tex](x_1, y_1)[/tex], the slope is given by change in y divided by change in x, that is:

[tex]m = \frac{\Delta_y}{\Delta_x} = \frac{y_1 - y_0}{x_1 - x_0}[/tex]

In this problem, y is always the same value, hence [tex]\Delta_y = 0[/tex] and [tex]m = 0[/tex], which means that the roof is not steep, and the correct option is:

No, the contractor does not believe the roof is steep because the slope is 0.

Answer:

depends on the cost of the snowmobiles but if it is this question:

Suppose that the cost of renting a snowmobile is 37.50 for 5 hours. What would be the cost of renting 2 snowmobiles for 5 hours?

then the answer is 75 dollars for renting 2 snowmobiles for 5 hours.

Step-by-step explanation:

Answer:

$15

I don't know the percentage.

Step-by-step explanation:

50 + 50 = 100,    2 + 2 = 4,      .50 + .50 = 1

100 + 4 = 104 + 1 = 105

100 - 90 = 10 plus the 5 left-over = 15

Histograms are used to represent data using bars

The dataset is given as:

3, 6, 5, 9, 12, 14, 18, 4, 13, 12, 4, 3, 11, 14

Rearrange in ascending order

3, 3, 4, 4, 5, 6, 9, 11, 12, 12, 13, 14, 14, 18

Calculate the range

[tex]\mathbf{Range = 18 - 3}[/tex]

[tex]\mathbf{Range = 15}[/tex]

Using 4 classes, the class width is

[tex]\mathbf{Width = \frac{Range } 4}[/tex]

[tex]\mathbf{Width = \frac{15} 4}[/tex]

[tex]\mathbf{Width = 3.75}[/tex]

Approximate

[tex]\mathbf{Width = 4}[/tex]

So, we have the following frequency table

Class   Frequency

3 - 7               6

7 - 11               1

11 - 15              6

Answer:

  a.  2/3

Step-by-step explanation:

The bar over the 6 means the digit is repeated indefinitely. A bit of algebra can turn a repeating decimal into a fraction. Let x represent the value of the repeating decimal.

  [tex]x=0.6\overline{6}\\\\10x=6.6\overline{6}\\\\10x-x=6.6\overline{6}-0.6\overline{6}\\\\9x=6\\\\x=\dfrac{6}{9}=\boxed{\dfrac{2}{3}}[/tex]

The attachment shows the long division of 2/3 gives a repeating decimal with a repeating digit of 6. You can tell the quotient repeats when the new dividend (after subtraction) is equal to a dividend you have seen before. In this case, the dividend is repeatedly 20, and the quotient digit is repeatedly 6.

The point of the long division is to show you that 2/3 is the correct answer choice for a rational number equivalent to 0.666...(repeating).

Answer:

x = 3/2y

y = 2/3x

Step-by-step explanation:

x = 3/2y

Swap sides so that all variable terms are on the left hand side

2x + 15 = 3y + 15

Subtract 15 from both sides

2x = 3y + 15 - 15

Subtract 15 from 15 to get 0

2x = 3y

Divide both sides by 2

2x/2= 3y/2

Dividing by 2 undoes the multiplication by 2

X = 3y/2

Y = 2/3x

Subtract 15 from both sides

3y = 2x + 15 - 15

Subtract 15 from 15 to get 0

3y = 2x

Divide both sides by 3

3/3y = 2/3x

Dividing by 3 undoes the multiplication by 3

y = 2/3x

Step-by-step explanation:

she gets $195 per week plus 3% on sale OVER $1000.

ok. so, her weekly sales were $7800.

that means we need to calculate 3% of ... $6800 !

as she gets the commission only on sales that are over $1000.

6800 = 100%

1% = 100%/100 = 6800/100 = 68

3% = 1%×3 = 68×3 = $204

so, she earned $195 + $204 = $399 per week

and as there are 52 weeks per year, she then earned

399×52 = $20,748 per year.

Answer:

Step-by-step explanation:

This question involves the concept of similar triangles.

The pair of triangles that are similar are "B and D".

A pair of triangles is termed as similar triangles if the two angles of both the triangles are equal to each other. Hence, we will check this condition for each pair given in the question.

A.

Only one angle is given to be equal for both the triangles, while the other two angles are unknown. Hence, this pair can not be termed as similar.

B.

For an isoceles triangle, two sides and two angles of the triangle are equal. Considering the 40° angle to be the equal angle, we can safely conclude that the two angles of both the triangles in the pair are the same. Hence, this pair can be termed as similar.

C.

Triangle 5 has angles: 30°, 90° and (180°-30°-90°) = 60°. While triangle 6 has angles: 30°, 70°, and (180°-70°-30°) = 80°. Since all the angles of both the triangles are different. Therefore, they can not be termed as similar.

D.

Triangle 7 has angles: 50°, 20° and (180°-50°-25°) = 105°. While triangle 6 has angles: 50°, 105°, and (180°-50°-105°) = 25°. Since all the angles of both the triangles are equal. Therefore, they can be termed as similar.

Answer:

110° = ∠AED

Step-by-step explanation:

Four sides polygon.  The sum of the angles = (n - 2)180; 4 - 2(180) = 360°

∠B + ∠D + ∠BCD + ∠DEB = 360°

92° + 98° + 86°  + ∠DEB = 360°

               276°  + ∠DEB = 360°

                          ∠DEB = 360° - 276°

                          ∠DEB = 84°  

Now ∠AEB + ∠BED + ∠AED = 360°    All exterior angles of any polygon = 360°

            166° + 84° + ∠AED = 360°

               250° + ∠AED = 360°

                 110° = ∠AED

Answer:

Area of the shape=241.2cm^2

Perimeter of the shape=76.08cm

Step-by-step explanation:

Find the base for the first triangle = tan(75°)=O/A

= A=30/tan(75°)

=A = 8.04cm (2decimal place)

Area of first triangle= 1/2×Base×height

=1/2×8.04cm×30cm

=120.6cm^2

So total area for the shape is = 2×120.6cm^2

=241.2cm^2

Perimeter of the shape = 2(30cm+8.04cm)

=76.08cm

Answer:

£54

Step-by-step explanation:

According to the ratio:

Bridget = 4/17

Brian = 9/17

Caroline = 4/17

____

So if Bridget and Caroline receive £48, that would mean £48 is 8/17 of the total amount. We can find 1/17 of the money by dividing £48 by 8.

48 / 8 = 6

And then multiply that by 9 to find 9/17 of the money (the amount Brian has).
