A family pays to park their car and buy tickets at a baseball stadium. The
table shows the linear relationship between the number of tickets and the total cost, including parking.

A. 11.50
B. 13.50
C. 17.00
D. 8.50

Answers

Answer:

D. 8.50

Step-by-step explanation:

A. 11.50

B. 13.50

C. 17.00

D. 8.50

The cost of each ticket will be $8.5. Then the correct option is D.

What is a linear equation?

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The slope of the line is given as,

m = (y₂ - y₁) / (x₂ - x₁)

A family pays to enter a baseball stadium, park their car, and purchase tickets. The table displays the linear correlation between the number of tickets issued and the overall expense, which includes parking.

The slope is given as,

m = (57.50 - 40.50) / (5 - 3)

m = 17 / 2

m = 8.5

Let 'y' represent the total cost, 'x' represents the cost of the ticket, and 'c' represents the cost of parking. Then the equation is given as,

y = 8.5x + c

The cost of each ticket will be $8.5. Then the correct option is D.

The answer is  [tex]\mathsf {\frac{2}{9}}[/tex].

We are given the equation :

Answer:

[tex]\dfrac{2}{9}[/tex]

Step-by-step explanation:

Given expression:

[tex]\sqrt[3]{\dfrac{8}{729}}[/tex]

[tex]\textsf{Apply exponent rule} \quad \sqrt[n]{a}=a^{\frac{1}{n}}:[/tex]

[tex]\implies \left(\dfrac{8}{729}\right)^{\frac{1}{3}}[/tex]

[tex]\implies \dfrac{8^{\frac{1}{3}}}{729^{\frac{1}{3}}}[/tex]

Rewrite 8 as (2 · 2 · 2) and rewrite 729 as (9 · 9 · 9):

[tex]\implies \dfrac{(2 \cdot 2 \cdot 2)^{\frac{1}{3}}}{(9 \cdot 9 \cdot 9)^{\frac{1}{3}}}[/tex]

Solve for m:
2 (m + 7) = -4- m
Your answer

Answers

Answer:

m = -6

Step-by-step explanation:

2 (m + 7) = -4 - m

2m + 14 = -4 - m

3m + 14 = -4

3m = -18

m = -6

Hopefully this helps!

Brainliest please?

Answer:

m = -6

Step-by-step explanation:

To solve this equation for m, we multiply out the left side to remove the parentheses:

2m + 14 = -4 - m

Next, we combine like terms:  2m and -m are like terms, as are 14 and -4:

3m = -18

Dividing both sides by 3 yields m = -6

Answer:

A = L x W

A = 3 3/4 x 1 1/2

A = (you do the math, 3 3/4 x 1 1/2 : )

Step-by-step explanation:

Hope this helps! Please gie brainliest

Answer:

The formula to find the AREA of a rectangle is as shown A=l x w

L meaning Lenght, which in this case is 3 [tex]\frac{3}{4}[/tex] ft.

W meaning width, which in this case is 1 [tex]\frac{1}{2}[/tex] ft.

Now that you know what the length and the width are, you want to multiply them like the formula A = l x w

A= 3 [tex]\frac{3}{4}[/tex]  x 1 [tex]\frac{1}{2}[/tex]

You want to create the fractions into a mixed number.

3 3/4 = 15/4

1 1/2 = 3/2

Now when you multiply it should look like this :

[tex]\frac{15*3 }{4*2}[/tex]  or 15x3 / 4x2

This will get you the mixed number of 45/8

Then you can covert the mixed number to a whole number which will be

5 5/8

This will get you the final answer of 5 [tex]\frac{5}{8}[/tex] ft. This is your area.
