A drive-in theater costs $20 per car, plus an additional fee of $4 per person. The cost, C, of the movie when p people are in the car can be represented by this equation: C = 20 + 4p Solve the equation for p to show How many people were in the car when the movie costed C dollars.

Answers

Answer 1

Answer:

[tex]P=\frac{C}{4} -5[/tex]

Step-by-step explanation:

Step one:

given

cost  per drive= $20

additional fee per person= $4

let the number of persons be p

and the total cost be C

The total cost function is expressed as

[tex]C=20+4p[/tex]

Step two:

Required:

We want to make P subject of the cost function

Take 20 to the other side we have

C-20=4p

divide through by 4

P=C-20/4

simplify

P=C/4-5

[tex]P=\frac{C}{4} -5[/tex]

What is the equation of a line perpendicular to y=-2/5X-1 that passes through (2,-8)

Answers

Answer:

[tex]y=\frac{5}{2}x-13[/tex]

Step-by-step explanation:

Given the equation

[tex]y=-\frac{2}{5}x-1[/tex]

comparing the equation with the slope-intercept form[tex]y=mx+b[/tex]

Here,

m is the slope b is the intercept

so the slope of the line is m = -2/5

As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line,

so  the slope of the perpendicular line will be: 5/2

Therefore, the point-slope form of the equation of the perpendicular line that goes through (2,-8) is:

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

[tex]y-\left(-8\right)=\frac{5}{2}\left(x-2\right)[/tex]

[tex]y+8=\frac{5}{2}\left(x-2\right)[/tex]

subtract 8 from both sides

[tex]y+8-8=\frac{5}{2}\left(x-2\right)-8[/tex]

[tex]y=\frac{5}{2}x-13[/tex]

(could you please show work)

Answers

Use distributive property on both sides

3(x+4)=3(x-5)

3(x)+3(4)=3(x)-3(5)

3x+12=3x-15

Subtract 3x from both sides

12=15.

So because this is a false statement the equation has no solution. So your answer is no solution. Hope this helps!!!

A concert is $250 per ticket and the cost of parking is free. This is expressed
as p(x) = 250x. If the profit is $6,000 how many tickets were sold?

Answers

Answer:

24

Step-by-step explanation:

p(x) = 250x

6000 = 250x

x = 24

Answer:

24 tickets

Step-by-step explanation:

p(x) = 250x

Substitute 6,000 for p(x)

6,000 = 250x

Divide each side of the equation by 250

24 = x

4.3

sorry not sure for this one :(

4.1

Cost of 22ltrs of petrol = Rs300

Cost of 1ltr of petrol = 300/22

= 150/11

= Rs13.63

4.2

distance = 330km = d

speed = 110km/hr = s

time = d/s

= 330/110

= 33/11

= 3hrs

SI = principal amount × rate of interest × time

= 2000 + 720

= Rs2720

Hamid has gained weight.
He now weighs 88kg, whish is higher than his normal weight
What is Hamid's normal weight?

Answers

The situation we have to find is how much weight Hamid has gained. There is no number so I’m just going to teach u how to find the original weight. So basically you have to subtract the weight that is gained from the current weight which will give you the answer to the normal weight.
Current weight-weight gained=normal weight
For example if he gained 5 kg
88-5=83 so his normal weight is 83kg

A rectangular prism has the following dimensions. The base has sides that are 3 cm. and 5 cm. and the height is 9 cm. How many squares with 1 cm edges can cover the entire surface area of the prism completely with no overlaps?

Answers

Answer:

174 squares

Step-by-step explanation:

I would start by finding the surface area of the rectangular prism. You can use 2(wl+hl+hw).

2(wl+hl+hw)

2(3*5+9*5+9*3)

2(15+45+27)

2(87)

174 cm^2

The area of squares 1 cm edges would be 1 because 1*1=1, so you could find how many of them would fit on the surface area by dividing 174 by 1, which equals 174.
