Which table of ordered pairs represents a proportional relationship?

Answer:

100 kilometers

Step-by-step explanation:

In order to answer this question, we are going to have to do some multiplication, division, and conversion! To get started, we have to multiply 20 cm by 500,000 to expand the distance to full-scale:

20 * 500,000 = 10,000,000

This is how many centimeters (cm) are between the towns. Now, we have to convert this into kilometers (km). There are 100,000 centimeters in a kilometer, so to convert we have to divide 10,000,000 cm by 100,000:

10,000,000 / 100,000 = 100

Our answer is 100 kilometers.

Answer:

Step-by-step explanation:

Mean = Sum of all values/ total no of values

There are six numbers .

Mean =

[tex]\frac{35+40+12+16+25+10}{6} \\\\= \frac{138}{6} \\\\=23[/tex]

Answer:

[tex]\boxed {\tt 23}[/tex]

Step-by-step explanation:

The mean can be found by adding all the values together and dividing by the number of values.

1. Add the values

2. Divide by the number of values

Count how many numbers are in the set of data. There are 6 values. Divide 138 by 6.

The mean of the data set is 23.

Hey there! I'm happy to help!

We want to multiply each term inside the parentheses by the number on the outside.

-3(-7)=21

-3(3z)=-9z

Therefore, our expression is 21-9z.

Now you know how to use the distributive property! Have a wonderful day! :D

Answer:

The various planets are thought to have formed from the solar nebula, the disc-shaped cloud of gas and dust left over from the Sun's formation. The currently accepted method by which the planets formed is accretion, in which the planets began as dust grains in orbit around the central protostar.

Step-by-step explanation:

Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. When this dust cloud collapsed, it formed a solar nebula—a spinning, swirling disk of material.

Answer:

The remaining materials from the sun's formation clumped together due to gravity.

Angle sum property if Triangles tells us that sum of angles of a triangle is equal to 180°.

So, First, we will find the third inner angle.

[tex]180 = y + 93[/tex]

[tex]y = 87[/tex]

Now, let us find x.

[tex]62 + 87 + x = 180[/tex]

[tex]149+ x = 180[/tex]

[tex]x = 31[/tex]

So, 31° is the answer. (c)

Answer:

35% discount

Step-by-step explanation:

We can first find what percent of 32 20.80 is.

This can be shown by using a percent proportion.

[tex]\frac{20.80}{32} = \frac{x}{100}[/tex]

We can cross multiply to find the value of [tex]x[/tex].

[tex]20.80\cdot100=2080\\\\2080\div 32 = 65[/tex]

So 20.80 is 65% of 32.

However, this is the percent of the original price. To find the discount, we have to subtract 65 from 100.

[tex]100 - 65 = 35[/tex]

So the book was on a 35% discount.

Hope this helped!

Answer:

There is no picture

Step-by-step explanation:

Answer:

[tex]y=3x[/tex] (Equation 1)

[tex]y=x-2[/tex] (Equation 2)

We can substitute Equation 1 into Equation 2 like so:

[tex]y=x-2[/tex]

[tex]3x=x-2[/tex]

Subtract x from both sides:

[tex]2x=-2[/tex]

Divide both sides by 2:

[tex]x=-1[/tex].

Substitute [tex]x=-1[/tex] into Equation 1 to find y:

[tex]y=3x[/tex]

[tex]y=3(-1)[/tex]

[tex]y=-3[/tex]

Answer:

The 12.6 oz bottle

Step-by-step explanation:

0.19/oz for the 12.6 oz

0.21/oz for the 25.3 oz

The size is the better buy based on the unit price is 12.6 oz bottle if a certain shampoo is available in two sizes.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

A certain shampoo is available in two sizes. A 12.6-ounce bottle costs $2.37. A 25.3-ounce bottle costs $5.24.

Let the unit price be x:

= 0.19/oz for the 12.6 oz

x = 0.21/oz for the 25.3 oz

Thus, the size is the better buy based on the unit price is 12.6 oz bottle if a certain shampoo is available in two sizes.

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-4,-8) and (8, 10)

The midpoint is

[tex]M = ( \frac{ - 4 + 8}{2} , \: \frac{ - 8 + 10}{2} ) \\ = ( \frac{4}{2} , \frac{2}{2} )[/tex]

Answer:

[tex]x=2[/tex]

Step-by-step explanation:

[tex]9 - 10x = 2x + 1 - 8x[/tex]

[tex]9-10x=-6x+1[/tex]

Subtract 9 from both sides:

[tex]9-10x-9=-6x+1-9[/tex]

[tex]-10x=-6x-8[/tex]

Add 6x to both sides:

[tex]-10x+6x=-6x-8+6x[/tex]

[tex]-4x=-8[/tex]

Divide both sides by -4:

[tex]\frac{-4x}{-4}=\frac{-8}{-4}[/tex]

[tex]x=2[/tex]

Answer:

x = 2

Step-by-step explanation:

9-10x = 2x+1-8x

1. move all like terms to one side

-10x-2x+8x = -9+1

2. simplify

-4x = -8

3. divide the -4 from both sides of the equation

x= -8/-4

4. x=2

Step-by-step explanation:

Answer: 17 nickels, and 8 dimes.

Step-by-step explanation:

So Miles has 25 coins in his pocket, Suppose that x is the number of nickels, and y is the number of dimes, then we have that:

x + y = 25

And we also know that the total value is $1.65

Then we have that:

x*0.05 + y*0.10 = 1.65

Then we have a system of equations:

x + y = 25

x*0.05 + y*0.10 = 1.65

The first step is isolating one of the variables in one of the equations, i will isolate x in the first one.

x = 25 - y

Now we can replace that in the second equation:

(25 - y)*0.05 + y*0.10 = 1.65

Now we solve this for y.

25*0.05 - y*0.05 + y*0.10 = 1.65

1.25 + y*(0.10 - 0.05) = 1.65

y*0.05 = 1.65 - 1.25 = 0.40

y = 0.40/0.05 = 8

So Miles has 8 dimes.

And:

x + y = 25

x + 8 = 25

x = 25 - 8 = 17

And Miles has 17 nickels.

Answer:

The charges of both companies will be same if truck is driven 200 miles per day

Company A will have better deal if truck is driven more than 200 miles per day ( because per mile rate of company A is less than company B

Step-by-step explanation:

Let the truck is driven X miles per day

Charges of company A will be = 90+0.4X

Charges of company B will be =30+0.7X

Let us find out value of X when charges of both companies are same

which means that   90+0.4 X= 30+0.7X

                            90-30      = 0.7X-0.4X

                            60    = 0.3X

                             60/0.3 = X

                             X= 200

Answer:

200 miles
