Answer:

r = 50000

P (r) = 0.7r - 35000

Step-by-step explanation:

Given cost function is

C (r) = 0.85r + 35000

and revenue function is

R (r) = 1.55r

At break even point, revenue is equal to cost

R(x)= C(x)

1.55r = 0.85r+35000

Subtract 0.85 from both sides

0.7r = 35000

divide by 0.7 on both sides

r = 50000

Profit function

P(x)= R(x)- C(x)

P(r) = 1.55r - (0.85r+35000)

P(r) = 1.55r - 0.85r - 35000

P(r) = 0.7r - 35000

Answer:

10 cups of milk

Step-by-step explanation:

Make a proportion, where x is the number of cups of milk for 165 cookies:

[tex]\frac{2/3}{11}[/tex] = [tex]\frac{x}{165}[/tex]

Cross multiply and solve for x:

11x = 110

x = 10

So, 10 cups of milk are needed to make 165 cookies

The points are basically numbers and use those points to help you figure out which equation is true or in you case best models the graph.

angle AOB = 100

=========================================

Explanation:

Angle x is an inscribed angle that subtends or cuts off minor arc AB. This is the shortest distance from A to B along the circle's edge.

Angle y is also an inscribed angle that cuts off the same minor arc AB. Therefore, it is the same measure as angle x. We can drag point D anywhere you want, and angle y will still be an inscribed angle and still be the same measure as x.

-------------------

Point O is the center of the circle. This is because "circle O" is named by its center point.

Angle AOB is considered a central angle as its vertex point is the center of the circle.

Because AOB cuts off minor arc AB, and it's a central angle, it must be twice that of the inscribed angle that cuts off the same arc.

This is the inscribed angle theorem.

Using this theorem, we can say the following

central angle = 2*(inscribed angle)

angle AOB = 2*(angle x)

angle AOB = 2*50

angle AOB = 100 degrees

Point-Slope form = y-y1=m(x-x1)

Y-6 = -1/3 (x+6)

Slope-intercept form = Y=mx+b

y = -1/3 + 4

The equation of line is y= -2/3x + 2.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx

where, m is the slope

Given:

Points: (​-6,6), (6,2)

Slope= (-2 - 6)/( 6 -(-6))

slope= -8 / 12

slope= -2/3

Now, using slope intercept form

y-b = m(x- a)

y- 6 = -2/3( x + 6)

y -6 = -2/3x - 4

y= -2/3x + 2

Hence, the equation of line is y= -2/3x + 2.

Answer:5x + 10y = 125

Step-by-step explanation

Number of nickel = x

Number of dime = y

Nickel = 5 cent

Dime = 10 cent

Total value = $1.25

Total value should be converted to cent since both dime and nickel are both in cent

= $1.25 * 100 = 125 cents

Therefore,

5x + 10y = 125 cents

6x - 9y = -12

Step-by-step explanation:

2x - 3y = -4  multiply both sides by 3 by adding paranthesis to represent this

3( 2x - 3y ) = 3 (-4)   Then use distributive property for the left side equation

6x - 9y = -12               Finally just multiply -4 by 3 and you get this equation

Step-by-step explanation:

Answer: 36

Step-by-step explanation:

As you can see, side AB is similar with side PQ.

Also, side BC is similar with side QR.

If you divide the length of side QR (34.5) by the length of side BC (11.5)

you get 3.

3 is the ratio that you will use to find the other side. The ratio of triangle ABC to  PQR is 1:3

Multiply the side of AB (12) by 3 and you will get 36.

The measure of side PQ in triangle PQR is 35 units. Therefore, option D is the correct answer.

Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.

Given that, triangle ABC is similar to triangle PQR.

By similar triangles statement, we have

AB/PQ = BC/QR

12/PQ = 11.5/34.5

12×34.5=PQ×11.5

11.5PQ=414

PQ=414/11.5

PQ=36

Therefore, option D is the correct answer.
