Step-by-step explanation:

The side length of perry's phone will be 8 inches.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

Given is Perry who wants to project a movie from his phone to a screen on the wall. The side length of the screen is 56 in. The scale from the screen to the phone is 7 in. to 1 in.

Assume the side length of perry's phone be [x] inches. Then, we can write the proportion as -

56/x = 7/1

x = 56/7

x = 8

Therefore, the side length of perry's phone will be 8 inches.

Answer:

O 81 km per hour

Explanation

Given parameters:

Number of days traveled  = 3 days

Distance covered on the first day  = 1080km

Time of travel  = 10hrs

Rate of travel  = 108km/hr

Time of travel on second day = 12hrs

Rate of travel  = 90km/hr

Time of travel on third day  = 18hrs

Rate of travel  = 60km/hr

Unknown

Average speed  = ?

To find the average speed, we sum the distances and divide by the sum of the time.

  Average speed  = [tex]\frac{Total distance}{total time}[/tex]

we do not know the second and third distances;

  Distance  = speed x time

D2  = 90 x 12 = 1080km

D3  = 60 x 18  = 1080km

    Now;

  Average speed  = [tex]\frac{1080 + 1080 + 1080 }{10 + 12 + 18 }[/tex]

 Average speed  = [tex]\frac{3240}{40}[/tex]   = 81km/hr

The average speed is 81km/hr

let's see what to do buddy...

Step-by-step explanation:

[tex] \frac{zinc}{copper} = \frac{3}{17} \\ \\ \frac{zinc}{799} = \frac{3}{17} [/tex]

Multiply the sides of the equation by 799

[tex]zinc = \frac{3}{17} \times 799 \\ \\ zinc = \frac{3}{17} \times 17 \times 47 \\ \\ zinc = 3 \times 47 = 141 [/tex]

So A jar of the chemical contains 141 grams of zinc.

And we're done.

Thanks for watching buddy good luck.

Step-by-step explanation:

Option 4 : Square A has side lengths a₁ =3, a₂= 3 and Square B has side lengths b₁=6,b₂=6 Then show that the ratio of corresponding side length is equal:  a₁ /a₂=b₁/b₂,  3/3=6/ 6  is the informal proof of the given conjecture.

Informal proofs are used to proof a theorem in different methods of  proving theorems and steps of the proof are not formally framed.

Mostly by taking a particular example a theorem is proved.

All square are similar.

This statement is true

∴ Option 1 is false

Option 2 is formal proof as sides of squares A and B are taken as variables x and y therefore this proof can be used for any pair of two squares

Option 3. is wrong proof as the  two sides of square A and B are taken unequal but square has all four sides equal.

Option 4 is correct proof but it is not a formal one as a particular example is taken to proof with statement

Therefore option 4 is the correct option that show the informal proof of the given statement.

Step-by-step explanation:

It is given that, ray Ray AP bisects angle CAT. It means,

[tex]\angle CAT=\angle CAP+\angle PAT[/tex]

Also, [tex]\angle CAP = \angle PAT[/tex]

It gives, [tex]\angle CAT=2\angle PAT[/tex]

ATQ,

[tex]\angle CAT = 5x+17 \ \text{and}\ \text{PAT}=3x-4[/tex]

Step-by-step explanation:

The ratio of the change in the y and x values, in the table gives the slope

graph of the linear function.

Correct response:

The slope of the linear function is -6

The slope of a line is defined as the change in y coordinate with respect to the change in x coordinate of that line. The net change in y coordinate is Δy, while the net change in the x coordinate is Δx. So the change in y coordinate with respect to the change in x coordinate can be written as, dx/dy.

here, we have,

Method used for finding the slope

From the given table, we have;

The first difference of the y-values = 2 - 8 = -6 = Constant

The rate of change of the x-values = 1 = Constant

Therefore;

The function is a linear function;

The slope, m, is given by the formula;

m = y2 - y1/x2-x1

Taking a pair of points as follows;

(0, -4) = (x₁, y₁)

(2, -16) = (x₂, y₂)

We have;

m = -6

The slope of the linear function, m = -6

Answer:

Uniform motion always travel in equal distances in equal intervals of time. So the graph will always be constant.

Once you draw the diagram of a uniform motion, when it comes to plotting points you can easily identify if the points go in a constant rate(uniform) or in  uneven distances(non-uniform).

Step-by-step explanation:

2(3y + 7 + 5) = 196 - 16

196 - 16= 180

2(3y + 7 + 5) = 180

6y + 14 + 10 = 180

6y + 24 = 180

6y = 180 - 24 = 156

6y = 156

y = 156 divided by 5

Answer:

30

Step-by-step explanation:

since the width is 20, there are 2 sides, so multiply by 2 and it's 40. Subtract 40 from 100 and you get 60. 60 is both lengths combined, so divide by 2 and you have 30 as your length. :)

Answer:

36300

Step-by-step explanation:

Answer:

The answer is 36,300.

Step-by-step explanation:

Okay, here's what we know, Jon has 60,500 cars and 60% of those cars are green. And what we are trying to figure out is how many cars are green.

So we need to convert the problem to an equation using the percentage formula: P% * C = G.

P stands for the percentage, C stands for the total number of cars, and G stands for the total number of green cars.

1. The percentage of green cars is 60% of all the cars. The variable C is 60,500, so the equation is 60% * 60,500 = G.

2. Convert 60% to a decimal by removing the percent sign and dividing by 100: 60/100 = 0.6.

3. Substitute 0.6 for 0.6% in the equation: 60% * 60,500 = G.

4. G becomes 0.6.

5. Do the math: 0.6 * 60,500 = 36,300.

6. G = 36,300.

So 60% of 60,500 is 36,300 and 36,300 cars are green

Let's double check our answer with the original question: What is 60% of 60,500?

Multiply 0.6 * 60,500 = 36,300

So yes, our answer is correct and Jon has 36,300 green cars.

The coordinate of the midpoint is 1/2

Step-by-step explanation:

Midpoint

The midpoint of a segment defined in a one-dimension system is

[tex]\displaystyle \bar x=\frac{x_1+x_2}{2}[/tex]

Where x1 and x2 are the coordinates of the points.

The given segment has endpoints x1=-7 and x2=8, thus:

[tex]\displaystyle \bar x=\frac{-7+8}{2}[/tex]

[tex]\displaystyle \bar x=\frac{1}{2}[/tex]

The coordinate of the midpoint is 1/2
