What equation models the data in the table if d = number of days and c = cost?

Days
2
3
5
6
Cost
6
9
15
18

A. c = 3d

B. d = 3c

C. c = d + 3

D. c = d + 3d

Answers

Answer 1

Answer:  A. c = 3d

I'm gonna go with c = 3d

Step-by-step explanation:  c = 3d

After looking at the table I believe the equation would be c=3d. I came to this conclusion because (6)=3(2); (9)=3(3); (15)=3(5); 18=3(6). I really hope this helps!:)

...................................................................................................................................................

Answer:

Step-by-step explanation:

Days  Cost

2          6

3          9

5         15

6         18

Now to find equation that models the given data we will use two point slope form.

Formula:

Substitute the values in the formula

where y denotes the number of days and x denotes the cost

Let us suppose d denotes the number of days and c denotes the cost

So, equation becomes:  

Hence an equation models the data in the table is  

So, option A is true.

Someone help Duane scored 55 points in the last basketball game, which is 10 points more than his previous personal best. LeBron scored 15 points more than Chris in the same game. LeBron scored the same number of points as Dwayne‘s previous personal best. Let D represent the number of points Dwayne scored during his previous personal best and C Represent the number of crest points. Question: how many points did Chris score during the game? If these are the only three players who scored, What was the teams totals number of points at the end of the game?

Answers

Answer:

130 points

Step-by-step explanation:

Given

[tex]Scorers: Duane,\ LeBron\ \&\ Chris[/tex]

[tex]D=Dwayne[/tex]

[tex]C = Chris[/tex]

[tex]L = LeBron[/tex]

So, we have:

[tex]L = 15 + C[/tex] --- 15 more than Chris

[tex]L =D -10[/tex] --- Same as Dwayne previous personal best

[tex]D = 55[/tex] -- Dwayne's point

Required

Find the total points

We have:

[tex]L = 15 + C[/tex]

[tex]L =D -10[/tex]

[tex]D = 55[/tex]

Substitute [tex]D = 55[/tex] in [tex]L =D -10[/tex]

[tex]L = 55 - 10[/tex]

[tex]L = 45[/tex]

Substitute [tex]L = 45[/tex] in [tex]L = 15 + C[/tex]

[tex]45 = 15 + C[/tex]

[tex]C =45 -15[/tex]

[tex]C =30[/tex]

So, we have:

[tex]D = 55[/tex]

[tex]L = 45[/tex]

[tex]C =30[/tex]

The total points is calculated as:

[tex]Total = D + L + C[/tex]

[tex]Total = 55 + 45 + 30[/tex]

[tex]Total = 130[/tex]

Kara runs two laps around a track. It takes her 51.495 seconds to complete her first lap and between 53 and 54 seconds to complete her second lap. Her total time for both laps is a whole number of seconds. How long, in seconds, does Kara take to complete her second lap?

Answers

Answer:

I believe the answer is 53.505 seconds.

Answer:

53/505

Step-by-step explanation:

Remark

You know that the time must be 53. something for the second lap. If the total of the first and second lap is a whole number, then all you need do is add something to 0.495 to get a whole number.

Method

What you have to do is add 1 - 0.495 to get the decimal to add to 53.

1 - 0.495 = 0.505 which will give you a whole number.

The answer then is 53.505

Answers

Answer:

3/50

Step-by-step explanation:

The experimental probability that a person selected at random is going to City B is 19/50.

What is the experimental probability?

Experimental probability is a probability that is determined on the basis of a series of experiments.

The table shows the results of a survey of 100 people selected at random at an airport.

The total number of responses is;

= 24 + 38 + 14 +22 +2

= 100

The experimental probability that a person selected at random is going to City B is given by;

[tex]\rm Probability =\dfrac{Responses \ from \ city \ B}{Total \ responses}\\\\ Probability =\dfrac{38}{100}\\\\ Probability =\dfrac{19}{50}[/tex]

Hence, the experimental probability that a person selected at random is going to City B is 19/50.

Find the perimeter of the figure to the nearest hundredth.

Answers

Answer:

42.84cm

Step-by-step explanation:

The perimeter is the sum of all the side length and the circumference of the semicircle

circumference of the semicircle = 2πr/2 = πr

circumference of the semicircle = 3.14 * (12/2)

circumference of the semicircle = 3.14 * 6

circumference of the semicircle = 18.84cm

Perimeter of the figure = 10cm + 6cm + 8cm + 18.84cm

Perimeter of the figure = 42.84cm (to nearest hundredth)

Erika is painting a rectangular painting. The painting has a length of 12 and a width of 10 inches. Use the Distributive Property to decompose the factor 12. Then find the area of the painting.

Answers

Given:

Length of the painting = 12 inches

Width of the painting = 10 inches

To find:

The area of the rectangular painting by using Distributive Property to decompose the factor 12.

Solution:

The area of a rectangle is

[tex]A=length\times width[/tex]

So, the area of the rectangular paining is

[tex]A=12\times 10[/tex]

Using Distributive Property to decompose the factor 12, we get

[tex]A=(10+2)\times 10[/tex]

[tex]A=(10\times 10)+(2\times 10)[/tex]

[tex]A=100+20[/tex]

[tex]A=120[/tex]

Therefore, the area of the rectangular painting is 120 square inches.

Solve the system of equations
-12x+9y=7
3x+4y=2
Show all workings please

Answers

Answer:

x = -2/15 & y = 3/5

Step-by-step explanation:

- 12x + 9y = 7 ...(1) ; 3x + 4y = 2 ...(2)

Multiply both sides of (2) by 4:

12x + 16y = 8

Add the new equation & (1):

12x + 16y = 8

-12x + 9y = 7

0 + 25y = 15 => y = 15/25 = 3/5

Thus, substitute the value of y in (2):

3x + 4y = 2 => 3x = 2 - 4(3/5) = (10-12)/5

=> 3x = -2/5

=> x = - 2/15

Answer:

[tex]x=-\frac{2}{15}=-0.133333333\\y = \frac{3}{5}= 0.6[/tex]

Step-by-step explanation:

−12x+9y=7

3x+4y=2

​In order to solve by elimination, coefficients of one of the variables must be the same in both equations so that the variable will cancel out when one equation is subtracted from the other.

−12x+9y=7,3x+4y=2

To make −12x and 3x equal, multiply all terms on each side of the first equation by 3 and all terms on each side of the second by −12.

3(−12)x+3×9y=3×7,−12×3x−12×4y=−12×2

Simplify.

−36x+27y=21,−36x−48y=−24

Subtract −36x−48y=−24 from −36x+27y=21 by subtracting like terms on each side of the equal sign.

−36x+36x+27y+48y=21+24

Add −36x to 36x. Terms −36x and 36x cancel out, leaving an equation with only one variable that can be solved.

27y+48y=21+24

Add 27y to 48y.

75y=21+24

Add 21 to 24.

75y=45

Divide both sides by 75.

y=3/5

Substitute 3/5 for y in 3x+4y=2. Because the resulting equation contains only one variable, you can solve for x directly.

3x+4×(3/5)=2

Multiply 4 times 3/5

3x+12/5=2

Subtract 12/5 from both sides of the equation.

3x=-2/5

Divide both sides by 3.

x=-2/15

The system is now solved.

x=−2/15 ,y=3/5

 

Solve the system using a matrix.
4x +
2y = 12
3x - y = -16
