Answer:

$16

Step-by-step explanation:

Let x =  how much money Bob has. (x)

Bob has twice as much money as Bob. (2x)

Paul has $12 more than Bill. (2x+12)

To find out how much money Bob has, we can add our expressions for each person and set them equal to 92.

x + 2x + 2x + 12 = 92

To simplify this equation, we first need to find the like terms and add them.

1x + 2x + 2x = 5x

5x + 12 = 92

Now that we have done that, we can find how much money Bob has by solving for x. First, we subtract 12 on both sides of the equation.

5x + 12 - 12 = 92 - 12

5x = 80

Then we divided by 5 on both sides of the equation.

5x/5 = 80/5

x = 16

Since x = 16, we know that Bob has 16 dollars.

Step-by-step explanation:

The nut that has the higher unit price is pecans.

The pecans cost $0.65 more than cashews.

Looking at the table of the cost of pecan, it can be seen that the cost of pecan increase by $10 for every 1 pound increase in weight.

Cost of one pound of pecan : $5 / 0.5 = $10

A linear function is a function that has one dependent variable and one independent variable. A linear function represents a straight line on a coordinate plane.

A linear function has the form: a + bx

Where:

y = 9.35x

Cost of one pound of cashew : 9.35 x 1 = $9.35

Difference in cost = $10 - $9.35 = $0.65

Answer:

x/12

Step-by-step explanation:

In terms of x with no dollar numbers provided, the amount LESS for 4 people versus 3 would be x/3 - x/4.  Getting 12 as the LCD and subtracting gives x/12 less to pay.

Using the motion equation we can get:

a) s = -16*t^2 + 1028

b) 992 feet above the ground.

c) after 8 seconds, the coin will hit the ground.

First, we know that the general height equation is:

s = -16*t^2 + v0*t + s0

In this case, the coin is dropped, so the initial velocity v0 is zero.

And the coin is dropped from a height of 1028 ft, then s0 = 1028

Replacing that in the equation we get:

s = -16*t^2 + 1028

b) The height after 1.5 seconds is what we get by evaluating the height equation in t = 1.5

s = -16*(1.5)^2 + 1028 = 992

This means that the height after 1.5 seconds is 992 ft above the ground.

c) The coin will strike the ground when s = 0, then we need to solve:

s = 0 = -16*(t)^2 + 1028

Solving that for t, w eget:

16*t^2 = 1028

t^2 = 1028/16

t = √(1028/16) = 8

This means that the coin will hit the ground after 8 seconds.

Answer:

2/19

Step-by-step explanation:

Rewrite the mixed number as an improper fraction. Frist, multiply 2x8 then add that to 3 to get 19/8. Now you have 1/4 / 19/8. Multiply by the reciprocal of the denominator. Now you have 1/4 x 8/19. 1 x 8 = 8. 4 × 19= 76. This gives you 8/76. You can simplify this by dividing the numerator and denominator by 4. This would give you 2/19.

From the given linear function, it is found that each descent by 88 meters was 11 seconds long.

The graph of the linear function is missing, and it is given at the end of the answer.

A linear function is modeled by:

y = mx + b

In which:

Given two points on the graph, the slope is given by change in y divided by change in x. For this problem, the points are given as follows:

(0, 440) and (40,0).

Hence the slope is:

m = (0 - 440)/(40 - 0) = -11.

Meaning that in each minute, he descended 8 meters. Thus the time to descend 88 meters is given by:

t = 88/8 = 11 seconds.

Each descent by 88 meters was 11 seconds long.

Answer:

y = -1/12x + 11

Step-by-step explanation:

An ordered pair is the form (x,y)  Us the x and y from the point and the slope to find the y intercept and then you can write the equation.

Use o for x and  11 and or y and - 1/12 for m

y = mx + b

11  = (-1/12)(0) + b

11 = b

y = -1/12x + 11

Answer:

Y = -1/12 x + 11

Step-by-step explanation:

Start with point (0,11)   slope ( -1/12)  form :

(y-11) = -1/12 (x-0)

      re-arrange to slope intercept form just by adding 11 to both sides

y = -1/12 x + 11

-13 + -13= -26

Table:

Miles    Hours

  5          4

  40       32

  45       36

The ratio between Miles and Hours is 5:4

In the table, miles = 40 is got by 8 x 5 = 40

So corresponding hours = 8 x 4 = 32

In the table, hours = 36 is got by 9 x 4 = 36

So corresponding miles = 9 x 5 = 45

So the ratios are 5:4 , 40:32, 45:36

Graph can be plotted with number of miles in the x-axis and number of hours in y-axis.

x=5

Step-by-step explanation:

step 1 : exapnding 2(x+4) will give you 2x +8 , the student made an error in expanding

so it should then be 2x+8 = 6x-12

and then if you move the letters to one side and the numbers to the other you will get :

-4x = -20

x=5

hope this works :)

x=5

Step-by-step explanation:

the student added a minus in 2x and 8 when it's suppose to be an addition that is the error

2(x+4)=6(x-2)

2x+8=6x-12

2x-6x=-8-12

-4x=-20

x= -20/-4= 5

The typical pace of change since the slide's start, -14/3.

Let, the average rate of change is k

(x1,y1) (x2,y2), k= (y2-y1)/(x2-x1)

=10-80/15

=-70/15

k=-14/3

Average = -14/3

Divide the change in y-values by the change in x-values to determine the average rate of change. Identifying changes in measurable parameters like average speed or average velocity calls for the knowledge of the average rate of change.

The average rate of change is a measure of how quickly on average one quantity changes in relation to another. It provides a general sense of the function's change in value per unit throughout the specified time period. Simply said, the rate of change is calculated by dividing the amount of change in one item by the equal amount of change in another. Let's take a closer look at the average rate of change formula.

The approximate length of string lights the staff needs to decorate the ceiling is 40.25

The complete question is added as an attachment

From the attached figure, we have the following coordinates

A = (5, 16)

B = (17, 10)

C = (14, 4)

D = (2, 10)

Calculate the lengths AB and BC using the following distance formula

d = √[(x2 - x1)^2 + (y2 - y1)^2]

This gives

AB = √[(5- 17)^2 + (16- 10)^2] = 13.4

BC = √[(14- 17)^2 + (4- 10)^2] = 6.7

The approximate length of string lights the staff needs to decorate the ceiling is then calculated as

P = 2 * (AB + BC)

This gives

P = 2 * (13.4 + 6.7)
