The manager of a restaurant found that the cost to produce 200 cups of coffee is $65.00 , while the cost to produce 250 cups i

PIT_PIT [208]

Answer:

a). y = 0.25x + 15

b). x = 480 cups

Step-by-step explanation:

(a). Let the equation of the linear function passing through a point (x', y') is,

y - y' = m(x - x')

'm' = slope of the line

b = y-intercept

Two points lying on the linear function will be (200, 65) and (250, 77.5).

Slope of the line 'm' = $\frac{y_2-y_1}{x_2-x_1}$

m = $\frac{77.5-65}{250-200}$

= $\frac{12.5}{50}$

= 0.25

Therefore, equation of the line passing through (200, 65) and slope 0.25 will be,

y - 65 = 0.25(x - 200)

y - 65 = 0.25x - 50

y = 0.25x + 15

(b). For y = $135 we have to calculate the number of cups of coffee produced.

135 = 0.25x + 15

0.25x = 135 - 15

0.25x = 120

x = 480 cups

Therefore, 480 cups of coffee will be produced.

If 0.65 AU equal 1 inch how much would 0.05 AU equal and explain.

mart [117]

Answer:

0.05 AU corresponds to the 0.0769 Inches(<em>This calculation is not possible in real time world)</em>

Step-by-step explanation:

Given:

0.65 corresponds to 1 inch

To Find:

0.05 AU corresponds to how many inches.

Solution:

<em>The AU is astronomical unit which is preferred as the mean distance between earth and sun.</em>

<em>AU is too big unit and used in space distance calculation.</em>

But here for mathematical calculation,

0.65 AU corresponds to 1 inch

then 0.05 AU corresponds to x inch(es)

Now cross multiplying the quantities we get ,

0.65x=0.05*1

x=0.05/0.65

x=0.0769 inches corresponds to 0.05 AU

(Preferred for this example only)

<em>(Remember that this calculation is hypothetical and practically incorrect to use it).</em>

So we’re doing these segment ratios things in my math period and I need help on problem two thank you!! :3

iragen [17]

Answer:

Step-by-step explanation:

There could be 2 3 4 6 or 12. You can use any number that divides evenly into 12. I don't think you can use 1 because the question says members. The next question is, do you include Sharon in the group (so she gives herself a share) and again I will answer yes. She has to get something out of the deal.

2: each member gets 3 red and 3 white. ( don't say 6 red and 6 white.)

3: Each member gets 4 in total 2 red and 2 white each

4: Each member gets 4 in total. This can be split 2 ways.

6: Each member gets 2 in total: 1 red and 1 white.

12: Each member gets 1. 6 get red and the others get white.

A two digit number has 6 more ones than tens. Twice the sum of the number and its reverse is 6 more than ten times the number. F

Alona [7]

The number with the given characteristics is 17

<h3>How to determine the numbers?</h3>

Let the tens be x and the units be y.

So, the number is 10x + y

The relationship between the digits is

y = x + 6

The relationship between the number and the reverse is

2(10x + y + 10y + x) = 6 + 10 * (10x + y)

Simplify the second equation

2(11x + 11y) = 6 + 100x + 10y

Open the brackets

22x + 22y = 6 + 100x + 10y

Substitute y = x + 6

22x + 22(x + 6) = 6 + 100x + 10(x + 6)

Expand

22x + 22x + 132 = 6 + 100x + 10x + 60

Collect like terms

22x + 22x - 100x - 10x = 6 + 60 - 132

Evaluate the like terms

-66x = -66

Divide by -66

x = 1

Substitute x = 1 in y = x + 6

y = 1 + 6

y = 7

Recall that the number is 10x + y

So, we have

Number = 10 * 1 + 7

Evaluate

Number = 17

Hence, the number is 17
