- Gabe earns 13.5 per hour

2.

x ------------------ 4  ---- 8 --------- 12 ------ 16

Earnings ----- 57 ---- 111 ------- 165------ 219

Step-by-step explanation:

See attachment for complete question

Solving (a): Gabe's earnings per hour,

To do this, we simply calculate the slope (m) of the table.

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

Where

[tex](x_1,y_1) = (3,40.5)[/tex]

[tex](x_2,y_2) = (6,81.0)[/tex]

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

[tex]m = \frac{81 - 40.5}{6 - 3}[/tex]

[tex]m = \frac{40.5}{3}[/tex]

[tex]m = 13.5[/tex]

Hence, Gabe earns 13.5 per hour

Solving (b): Jordan earnings

First, we calculate the equation of Gabe's table using:

[tex]y - y_1 = m(x - x_1)[/tex]

Where

[tex]m = 13.5[/tex] and [tex](x_1,y_1) = (3,40.5)[/tex]

[tex]y - 40.5 = 13.5(x - 3)[/tex]

[tex]y - 40.5 = 13.5x - 40.5[/tex]

[tex]y = 13.5x[/tex]

If Jordan earns 3 more per hour than Gabe, then: Jordan's equation would be;

[tex]y = 13.5x + 3[/tex]

When x  = 4

[tex]y = 13.5*4 + 3 = 54 + 3 = 57[/tex]

When x = 8

[tex]y = 13.5*8 + 3 = 108 + 3 = 111[/tex]

When x = 12

[tex]y = 13.5*12 + 3 = 162 + 3 = 165[/tex]

When x = 16

[tex]y = 13.5*16 + 3 = 216 + 3 = 219[/tex]

Answer and Step-by-step explanation:

[tex]\frac{x}{2}[/tex] is the answer.

The initial part is having the person walk a certain amount (shown as x feet). Then, the amount of x (in terms of feet) is halved, or divided by 2.

Answer:

A) Juan wins the race

B) J(t) = A (t) at (7 minutes, 2 miles)

C) The interval is 7 minutes to 15 minutes

Step-by-step explanation:

a) Juan wins the race

The reason is that the time Juan took to cover the distance of 4 miles is shorter than the time Antonio took

b) J(t) = A(t) at what point

This simply refers to the point at which the two graphs cross over one another

We can see this at the point ; (7,2)

This is; 7 seconds and 2 miles

What this mean is that they both covered 2 miles in 7 seconds

c) interval where J(t) > A(t)

This is the interval at which Juan was ahead of Antonio

Juan was below within 7 minutes

after 7 minutes he picked up

so the interval is 7 minutes - 15 minutes

Answer:

11

Step-by-step explanation:

1+red/3=4/1 so 1+red=12 so red=11. we should add 11 red counters

Answer:

Add 15 red counters

Step-by-step explanation:

Number of red counter is 1

Number of blue counter is 3

1:3⇒4:1

Now to make ratio reverse you need to add 11 (12-1) more red counters so that ratio becomes

12:3=4:1

The coterminal angle of  angle  [tex]\frac{7\pi}{8}[/tex] is [tex]\frac{23\pi}{8}[/tex].

The coterminal angles are the angles that have the same initial side and the same terminal sides.

To determine the coterminal angle of a given angle just adding or subtracting 360° or 2π to it.

The  coterminal angle of  angle  [tex]\frac{7\pi}{8}[/tex] is,

                   [tex]2\pi+\frac{7\pi}{8}=\frac{16\pi+7\pi}{8} =\frac{23\pi}{8}[/tex]

The polygon has 6 sides.

'A polygon, in geometry is any closed curve consisting of a set of line segments (sides) connected such that no two segments cross.'

According to the given problem,

Sum of measures of angle = 720

We know,

Sum of interior angles of polygon = 180( n - 2 )

Where, n = number of sides.

⇒ 180( n - 2 ) = 720

⇒ n - 2 = 720/180

⇒ n - 2 = 4

⇒ n = 6

Hence, we can conclude that the polygon has 6 sides.

Answer:

148º

Step-by-step explanation:

Use the information given:

With R=32º, we can find angle QST and PQR. Angle QST=2(32)+8=64+8=72º. So angle PQR=180º-72º=108º. The sum of a quadrilateral's interior angles is 360º:

Answer: P(x) = 20x - 96,000

Step-by-step explanation:

Cost revenue and profit function.

Cost function;

C(x)= 40x + 96,000

Revenue function;

R(x)= 60x

Profit = Revenue - Cost

P(x) = 60x - (40x + 96,000)

P(x) = 20x - 96,000

Answer:

y = ⅔x - 5

Step-by-step explanation:

To write the equation, find the slope (m), to enable you write the equation of the line in point-slope form given a point, (-3, -7) that the line passes through.

Since the line is parallel to 2x - 3y = 24,, it would have the same slope (m) value.

Rewrite 2x - 3y = 24 in slope-intercept form.

Thus:

2x - 3y = 24

-3y = -2x + 24

y = ⅔x - 12

The slope of 2x - 3y = 24 is ⅔. Therefore, the line that is parallel to 2x - 3y = 24 is also ⅔.

To write the equation of the line, substitute (a, b) = (-3, -7) and m = ⅔ into y - b = m(x - a)

Thus:

y - (-7) = ⅔(x - (-3))

y + 7 = ⅔(x + 3)

y + 7 = ⅔x + 2

y = ⅔x + 2 - 7

y = ⅔x - 5

Answer:

The bag will make 432 pieces of popcorn.

Step-by-step explanation:

From the information given, you know that the bag has an average of 450 kernels and that 4% don't pop. So, with this information you can find the pieces of popcorn that the bag will made by calculating 4% of the average number of kernels in a bag and subtracting the result from that amount:

450*4%=18

450-18=432

According to this, the answer is that the bag will make 432 pieces of popcorn.
