The up front payment costs $34.5 while the payment per miles driven is $0.5

We are told that when renting a vehicle from Schrader car rental, a customer pays a fee up front, and is also charged for miles driven when they return.

Let the amount paid up front be x and let the amount paid per mile driven be y.

Thus, the equation for Henry will be;

x + 85y = 77   -------(1)

The equation for Marcia will be;

x + 115y = 83   ------(2)

Subtract eq 1 from eq 2 to get;

30y = 6

y = 6/30

y = $0.5

Thus;

x + 85(0.5) = 77

x = 77 - 42.5

x = $34.5

Answer:

y = 5

Step-by-step explanation:

A line with a slope of 0 is a horizontal line parallel to the x- axis with equation

y = c ( c is the value of the y- coordinates the line passes through )

the line passes through (- 4, 5 ) with y- coordinate 5 , then

y = 5 ← equation of line

Answer:

y=2/5x + 33/5

Step-by-step explanation:

To find the equation of the line that passes through the point (-9,3) and is perpendicular to y = 1/2x + 6, we can first find the slope of the given line y = 1/2x + 6. The slope of a line is equal to the rise (the change in the y-coordinate) divided by the run (the change in the x-coordinate), so we can find the slope of the line y = 1/2x + 6 as follows:

Slope = (change in y) / (change in x)

= (1/2 - 6) / (1 - 0)

= -5/2

Since the line we are looking for is perpendicular to the line y = 1/2x + 6, its slope must be the negative reciprocal of the slope of y = 1/2x + 6. The negative reciprocal of a number is equal to the negative of the reciprocal of the number, so the slope of the line we are looking for is equal to -1 / (-5/2) = 2/5.

Next, we can use the point-slope form of a line to find the equation of the line that passes through the point (-9,3) and has a slope of 2/5. The point-slope form of a line is given by the equation y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope of the line. Substituting the values for the given point and the slope into this equation, we get:

y - 3 = 2/5(x - (-9))

y - 3 = 2/5(x + 9)

Next, we can distribute the 2/5 on the right-hand side of the equation to get:

y - 3 = 2/5x + 18/5

Finally, we can combine like terms on both sides of the equation to get the final equation of the line:

y=2/5x + 18/5 + 3

y=2/5x + 33/5

Answer:y=3x+32

π/32 is the area enclosed by the curve r= sin(8θ)

The given curve is polar curve and hence the area of the polar curve is given by:

Let A be the area of the curve so,

A = [tex]\int\limits^a_b {\frac{1}{2} r^2 } \, d\theta[/tex]

where a and b is the boundary at which r=0

so after equation r=0

sin(8θ) =0

=> sin(8θ) =0

=> 8θ = 0,π

=> θ = 0, π/8

so a=0 , b= π/8

now  

   A = [tex]\int\limits^a_b {\frac{1}{2} r^2 } \, d\theta[/tex]    ------(i)

 so   [tex]r^2[/tex] = (sin(8θ))^2

=>  [tex]sin^2[/tex] ( 8θ )

ans we know that

cos(2α) = 1 -  2[tex]sin^2[/tex] α

so   [tex]r^2[/tex]  = (1- cos(16θ) )/2

putting the value of r in the equation (i) we get :-

A = [tex]\int\limits^a_b {\frac{1}{4} *(1-cos(16\alpha ) } \, d\alpha[/tex]

=> 1/4* [tex]\int\limits^a_b {(1-cos(16\alpha ) } \, d\alpha[/tex]

here a=0 and b=π/8

after putting the value and solving the integral

A = π/32

so A is the area enclosed by r=sin(8θ) is π/32

Answer:

The coordinates of B is (4, 7)

Step-by-step explanation:

To find the answer for B, you have to do the inverse of the midpoint formula, which is M equals (x1 multiplied by x2, over 2; y1 multiplied by y2, over 2).

If you substitute in A's coordinates for x1 and y1, you come up with (3, 3) = (2+x, over 2; and -1+y, over 2)

If the x coordinate answer for AB was 3, you can create an equation like this to solve for B's x coordinate: 2+x over 2 equals 3.

         you multiply 2 by 3 to get 6---> 2+x=6-----> x=4

If the y coordinate for AB was also three, you can create another equation to solve for B's y coordinate: -1+y over 2 equals 3.

        you multiply 2 by 3 to get 6 again---->so -1+y=6---->y=7

so the answer for B's coordinates is (4, 7).

The number of scholars who voted for the play named Wicked will be equal to 48.

This problem can be solved by using the concept of Ratio. It is given that the total number of students are 240. Now, the ratio of Annie to Wicked is equal to 5:2 and ratio of Wicked to Wizard Oz is equal to 2:3. If we assume that the number of people who voted for Annie is 'x', the number of people who voted for Wicked is 'y' and number of people who voted for Wizard Oz is 'z'. Now, we write the expressions as

x/y = 5:2; from this we get x = 5y/2                              ....(1)

y/z = 2:3; from this we get z = 3y/2                              ....(2)

x + y + z = 240                                                               ....(3)

We use the above values of equation (1) and (2) in equation (3) as

5y/2 + y + 3y/2 = 240

4y + y = 240

5y = 240

Thus, we would have c = 52/x cans per bag. This is probably the answer you are looking for.

If the width of a rectangle is two feet less than the length and the perimeter is 52 feet, then the length and width of the rectangle is 14 feet and 12 feet respectively

The width of a rectangle is two feet less than the length

Consider the length of the rectangle as x

Then the width of the rectangle = x - 2

The perimeter of the rectangle = 52 feet

The perimeter of the rectangle = 2(l + w)

Where l is the length and w id the width

Substitute the values in the equation

2(x + x - 2) = 52

2(2x - 2) = 52
