Reba works at a starbucks coffee shop where a 120z cup of coffee costs $1.65, a 160z cup costs $1.85, and a 20oz cup cost $1.95. During one busy period, Reba served 55 cups of coffee, emptying six 1440z brewers while collecting a total of $99.65. How many cups of each size did reba fill?

Answers

Answer:

Cups of 120oz sold = 17

Cups of 160oz sold = 25

Cups of 200oz sold = 13

Step-by-step explanation:

We know that:

a 120z cup of coffee costs $1.65

a 160z cup costs $1.85

a 200oz cup cost $1.95

Let's define the variables:

A = # of 120z cups that she sold

B = # of 160oz cups that she sold

C = # of 200oz cups that she sold.

We know that:

"Reba served 55 cups of coffee"

A + B + C = 55.

"emptying six 1440z brewers while"

A*120oz + B*160oz + C*200oz = 6*1440oz

"collecting a total of $99.65"

A*$1.65 + B*$1.85 + C*$1.95 = $99.65

Then we have a system of equations:

A + B + C = 55

A*120oz + B*160oz + C*200oz = 6*1440oz

A*$1.65 + B*$1.85 + C*$1.95 = $99.65

To solve this, the first step is to isolate one of the variables in one of the equations, let's isolate A in the first one:

A = 55 - B - C

Now we can replace that into the other two equations:

(55 - B - C)*120oz + B*160oz + C*200oz = 6*1440oz

(55 - B - C)*$1.65 + B*$1.85 + C*$1.95 = $99.65

Now we can rewrite those equations as:

B*40oz + C*80oz = 8640oz - 55*120oz = 2040oz

B*$0.20 + C*$0.30 = $99.65 - 55*$1.65 = $8.90

Now we have the system:

B*40oz + C*80oz = 2040oz

B*$0.20 + C*$0.30 = $8.90

Now we need to isolate another variable in one of the equations, let's isolate B in the first one:

B = 2040oz/40oz - C*80oz/40oz = 51 - 2*C

Now we can replace this in the other equation and get:

(51 - 2*C)*$0.20 + C*$0.30 = $8.90

Bow we can solve this for C.

$10.20 - C*$0.40 + C*$0.30 = $8.90

$10.20 - $8.90 = C*$0.10

$1.30 = C*$0.10

($1.30/$0.10) = C = 13

Now we can replace this in the equation:

B = 51 - 2*C = 51 - 2*13 = 25

And for A, we had:

A = 55 - B - C = 55 - 25 - 13 = 17

Then:

Cups of 120oz sold = 17

Cups of 160oz sold = 25

Cups of 200oz sold = 13

Which choice is equivalent to the quotient shown here when x > 0?

Answers

The answer should be D.
The square root of two.

The simplified expression is 3(x√2 + √x), which means that the answer is (C) x²√2.

What is an expression?

In mathematics, an expression is a combination of numbers, variables, operators, and functions that can be evaluated to produce a numerical value or another mathematical object such as a polynomial, equation, or inequality.

We can simplify the given expression by factoring out the greatest perfect square factor under each square root symbol. For the first term, √18x³, we can factor out √9x², which is 3x√2. For the second term, √9x, we can factor out √9, which is 3. Thus, we have:

√18x³ + √9x = √(9x²⋅2x) + √(9⋅x) = 3x√2 + 3√x

We can then factor out 3 from both terms:

√18x³ + √9x = 3(x√2 + √x)

Therefore, the simplified expression is 3(x√2 + √x), which means that the answer is (C) x²√2.

If the slope of y=2x+5 is changed to -2, how does the graph change?

Answers

you go down 2 and then right 5

The positive graph of y = 2x + 5 changes to the negative graph which moves downward from left to right when the slope is changed to -2.

What is Slope?

Slope of a line is defined as the difference in the y coordinates divided by the difference in the x coordinates of two points.

Slope of a line is usually denoted by the letter m.

First let us take the graph of y = 2x + 5.

Take x intercept and y intercept of this graph.

x intercept is the point where line touches X axis and y intercept is the point where line touches Y axis.

From the equation of the line, y intercept = 5

So we get a point (0, 5)

Now to find x intercept, let y = 0 in the equation, then x = -2.5

So we get another point (-2.5, 0)

So the line y = 2x + 5 passes through the points (0, 5) and (-2.5, 0).

Now if the slope changed to -2, equation becomes y = -2x + 5.

y intercept is same.

So one point of the line will be (0, 5)

To find x intercept, let y = 0 in the second equation, then x = 2.5

So the second line passes through the points (0, 5) and (2.5, 0)

That is, the graph which goes upward from left to right changed to the graph downward from left to right.

Hence, when the slope changed to -2, the graph goes downward from left to right.
