Answer:

[tex]y = 0.42x+55[/tex]

Step-by-step explanation:

Given

Let:

[tex]x \to miles[/tex]

[tex]y \to amount[/tex]

[tex](x_1,y_1) = (138,112.96)[/tex] ---- Bobs'

[tex](x_2,y_2) = (209,142.78)[/tex] --- Carl

Required

The equation

First, calculate the slope (m)

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

[tex]m = \frac{142.78 - 112.96}{209 - 138}[/tex]

[tex]m = \frac{29.82}{71}[/tex]

[tex]m = 0.42[/tex]

The equation is calculated using:

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

So, we have:

[tex]y = 0.42(x - 138) + 112.96[/tex]

[tex]y = 0.42x - 57.96 + 112.96[/tex]

[tex]y = 0.42x+55[/tex]

Answer:

2/3

Step-by-step explanation:

P ( 8 or more) = number that are 8 or more) / total

                        = (6+4) / ( 2+3+6+4)

                         = 10/15

                          =2/3

Answer:

7 boxes

Step-by-step explanation:

We can use ratios to solve

12 bars            42 bars

----------    = ---------------

2 boxes      x boxes

Using cross products

12x = 2 *42

12x = 84

Divide by 12

12x/12 = 84/12

x = 7

Answer:

a) 19/20

b) 1/20

Step-by-step explanation:

a) calculate the fraction of the attendants time will be spent servicing cars

l / L > 0 =  Ц / [ Ц -  λ ] = 20 --- ( 1 )

Ц (service )  = 15 hour

∴ λ ( arrival rate )  = 14.25

P = λ / Ц  = 14.25 / 15 = 0.95 = 19/20

b) Fraction of potential customers lost

Ls = P / ( 1 - P )

where ; P = 19/20

Ls ( fraction of potential customers lost ) = 19/20 / ( 1 - 19/20 )  = 19

hence proportion of customers lost = 1 - 19/20 = 0.05 = 1/20

Answer:

0.393701 cm = 1 in

Step-by-step explanation:

We want to find the number of centimeters in 1 inch.

First, the two conversion rates we need to use:

1m = 100 cm

1m = 39.3701 in

From these two equations, we can conclude that:

100cm = 1m = 39.3701 in

100cm = 39.3701 in

Because we want to find the total number of centimeters in 1 inch, we need to divide both sides by 39.3701

We will get:

(100cm)/39.3701 = (39.3701 in)/39.3701

0.393701 cm = 1 in

This equation gives us the number of centimeters in one inch.

Your Answer is in the above image

Answer:

4 in

Step-by-step explanation:

area right : Ar = 5x

area left : Al = 11x

area top : At = 5x

area bottom : Ab = 13x

area front : Afr = rectangle 13×11 minus area triangle

triangle (right-angled) : (11-5)×(13-5)/2 = 24 in²

Afr = 13×11 - 24 = 119 in²

area back = area front = 119 in²

sloped area : As = 10x

all individual shapes in the surface of the object are rectangles except the 2 areas in the front and in the back, where we had to calculate the complete rectangle and then subtract the cut off triangle area.

so, in total we have

414 = 5x+11x+5x+13x+119+119+10x = 44x + 238

176 = 44x

x = 4 in

Answer:

Let the total number of pupil be x.

Given that,

Number of pupils that received a grade of 90=9

Percentage of pupil that receive a grade of 90=18%

So,

18% of x=9

18x/100=9

x=50

Hence, there are 50 pupils in the class.

Answer:

36x² + 24x + 300 ft²

Step-by-step explanation:

→ Area of rectangle = Length × Width

→ Area of rectangle = (12x + 8) ft × (3x + 15) ft

→ Area of rectangle = 12x(3x + 15) + 8(3x + 15) ft²

→ Area of rectangle = 36x² + 180 + 24x + 120 ft²

→ Area of rectangle = 36x² + 24x + 300 ft²

Answer:

87.5 square inches

Step-by-step explanation:

(For Diagram,Please Find in Attachment)

Given, in diagram of the belt Knuckle there are 4 Triangles (2 are of same dimensions & another 2 are of same dimensions) and a Rectangle .

Now For Area of belt Knucle, We have to First Calculate the area of 4 triangles and Area of Rectangle.

∴ Area of 2 Triangle with given dimensions ( height = 2.5 inches & base = 9 inches )

Area = 2×(1/2×b×h) ⇔ 2×(1/2×9×2.5)

Area= 22.5 square inches

∴ Area of another 2 triangle with given dimensions ( height = 5 inches & base = 4 inches )

Area = 2×(1/2×b×h) ⇔ 2×(1/2×4×5)

Area= 20 square inches

∴Area of Rectangle with given dimensions ( Length = 9 inches & Width = 5 inches )

Area= length × Width ⇔ 9×5 ⇒ 45 square inches

Now, Area of belt Knucle=Sum of Area of 4 Triangles + Area of Rectangle

Area of belt Knucle = 87.5 square inches

Answer:

Step-by-step explanation:

Integrating each term with respect to x, we get:

            x^3          x^2

f(x) = 9--------- + 4------- - 4x + C

               3            2

We are told that if x = 0, f(x) = -7, and so C must equal - 7.  

The solution is

            x^3          x^2

f(x) = 9--------- + 4------- - 4x - 7,   or   f(x) = 3x^3 + 2x^2 - 4x - 7

               3            2

Answer: When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x).

Reflection in the y -axis:

The rule for a reflection over the y -axis is (x,y)→(−x,y) .

Reflecting over any other line. Notice how each point of the original figure and its image are the same distance away from the line of reflection (x = –2 in this example).

It is simple enough to identify whether or not a given function f(x) is a linear transformation. Just look at each term of each component of f(x). If each of these terms is a number times one of the components of x, then f is a linear transformation. are linear transformations.

First shift three units to the left, so the line of reflection becomes the y axis, then flip, and finally remember to shift three units back to the right to put the center line back where it belongs. (This gives the f(6−x) solution you already know).

Answer:

-4

Step-by-step explanation:

f(x) = 10 - 2x

substitute 7 in place of x

f(7) = 10 -2*7

=10 - 14

=-4

therefore the value of f(7) is -4.

Answer:

1979

91%

Step-by-step explanation:

Given the relation :

P = (318t + 6792) / (1.19t + 107.36)

P = % of household with PC

t = years since 2000

1.) We need to find t, when P = 85%

P = 0.85

0.85 = (318t + 6792) / (1.19t + 107.36)

0.85(1.19t + 107.36) = (318t + 6792)

1.0115t + 91.256 = 318t + 6792

Collect like terms :

1.0115t - 318t = 6792 - 91.256

−316.9885t = 6700.744

t = 6700.744 / - 316.9885

t = - 21.138760

t = - 21 years

2000 - 21 years = 1979

Percentage who had computer in 2014

t = 2014 - 2000 = 14

P = (318(14) + 6792) / (1.19(14)+ 107.36)

P = (4452 + 6792) / (16.66 + 107.36)

P = 11244 / 124.02

P = 90.6627

P = approximately 91%
