Answer:

Cost of student ticket =  $7

Cost of Adult ticket = $17

Step-by-step explanation:

Let cost of student ticket = x

Cost of Adult ticket = y

Making expressions from statements

Mrs. Levin bought 27 student tickets and 25 adult tickets, which cost a total of $614. [tex]27x+25y=614[/tex]

Mr. Lawson spent $733, getting 27 student tickets and 32 adult tickets. [tex]27x+32y=733[/tex]

Now solving these equations to find values of x and y

Let

[tex]27x+25y=614--eq(1)\\27x+32y=733--eq(2)[/tex]

Subtracting both equations

[tex]27x+25y=614\\27x+32y=733\\-\:\:\:-\:\:\:\:\:\:\:\:\:\:\:\:-\\-------\\-7y=-119\\y=\frac{-119}{-7}\\y=17[/tex]

So, we get value of y = 17

Now, finding value of x, by putting value of y in eq(1)

[tex]27x+25y=614\\Put\:y=17\\27x+25(17)=614\\27x+425=614\\27x=614-425\\27x=189\\x=\frac{189}{27}\\x=7[/tex]

So, we get value of x = 7

Cost of student ticket = x = $7

Cost of Adult ticket = y = $17

Equation 3

Step-by-step explanation:

Answer:Equation 3

linear functions dont have exponents

Step-by-step explanation:

The statement is False.

Given that the SP is $0.60 per unit and the CP is $0.36 per unit.

So, profit per unit = $(0.60-0.36)

                            = $ 0.24

So, now we have to check whether 2500 units sales is required if we want a profit of $900.

To check we have to multiply the profit per unit with the sales,

      ⇒ 0.24 × 2500

      ⇒ $ 600

We can see clearly that we get a profit of $600 if we sale 2500 units. So, to make a profit of $900 we have to sale = [tex]\frac{900}{0.24}[/tex]

                                                                = 3750 units

Answer:

[tex]Area = 72[/tex]

Step-by-step explanation:

From the attachment, we can see that the floor has a trapezium shape with the following dimensions.

[tex]Height = 6yd[/tex]

The parallel sides (P1 and P2) are:

[tex]P_1 = 10 + 4 = 14[/tex]

[tex]P_2 = 10[/tex]

The square yard needed to cover the floor is the area of the trapezium surface and this is calculated as follows:

[tex]Area =\frac{1}{2} * (Sum\ of\ parallel\ sides) * Height[/tex]

[tex]Area =\frac{1}{2} * (P_1 + P_2) * Height[/tex]

[tex]Area = \frac{1}{2} * (10 + 14) * 6[/tex]

[tex]Area = \frac{1}{2} * (24) * 6[/tex]

[tex]Area = 12 * 6[/tex]

[tex]Area = 72[/tex]

Hence, 72 square yards is needed to cover the floor

Step-by-step explanation:

Answer:

m∠BAC = 105°

m∠FAB = 75°

Step-by-step explanation:

By using the property of an exterior angle of a triangle,

Measure of an exterior angle is equal to the sum of opposite two angles of a triangle.

From the triangle given in the picture,

m∠ABC + m∠BCA + m∠CAB = 180°

(13x - 3)° = (3x + 2)° + 55°

13x - 3 = 3x + 57

13x - 3x = 57 + 3

10x = 60

x = 6

m∠FAB = (13x - 3)° = 75°

m∠ABC = (3x + 2)° = 20°

Since, ∠BAC and ∠FAB are the linear pair of angles,

m∠BAC + m∠FAB = 180°

m∠BAC + 75° = 180°

m∠BAC = 180° - 75° = 105°

Hey there!

The formula is: y₂ - y₁ / x₂ - x₁

y₂ = 22

y₁ = 21

x₂ = 6

x₁ = 5

Your equation: 22 - 21 / 6 - 5

22 - 21 = 1 ← numerator (TOP number)

6 - 5 = 1 ← denominator (BOTTOM number)

We can say that the line that passes through lines (5 , 21) (6 , 22): 1/1

(or you can simply 1 because 1 ÷ 1 gives you 1)

Good luck on your assignment and enjoy your day!

Answer:

Step-by-step explanation:

1. Alternate interior angles. Inside the transversal and opposing sides

8. Set all three angles equal to 180, since they're supplementary

34+41+x = 180

180 = 75+x

105 = x

You can tell if a graph represents a proportional relationship by identifying the y-intercept, or the point of the line that crosses the y-axis.

If the y-intercept is 0, then the relationship is proportional. This is called a direct relationship.

If the y-intercept is anything other than 0, then the relationship is not proportional. This is called an indirect relationship.

Complete Question:

An object dropped from rest from the top of a tall building on Planet X falls a distance d(t)=13t^2 feet in the first t seconds. Find the average rate of change of distance with respect to time as t changes from t1=2 to t2=10. This rate is known as the average velocity, or speed.

The average velocity as t changes from 2 to 10 seconds is _______ feet/sec?

Answer:

[tex]v = 156[/tex]

Step-by-step explanation:

Given

[tex]d(t)=13t^2[/tex]

Time Interval: (a,b)

[tex]a = 2[/tex]

[tex]b = 10[/tex]

Required

Determine the average rate of change (v)

This is calculated as thus:

[tex]v = \frac{d(b) - d(a)}{b - a}[/tex]

Substitute values for b and a

[tex]v = \frac{d(10) - d(2)}{10 - 2}[/tex]

[tex]v = \frac{d(10) - d(2)}{8}[/tex]

Calculate d(10): Substitute 10 for t

[tex]d(t)=13t^2[/tex]

[tex]d(10) = 13 * 10^2[/tex]

[tex]d(10) = 13 * 100[/tex]

[tex]d(10) = 1300[/tex]

Calculate d(2): Substitute 2 for t

[tex]d(t)=13t^2[/tex]

[tex]d(2) = 13 * 2^2[/tex]

[tex]d(2) = 13 * 4[/tex]

[tex]d(2) = 52[/tex]

The equation [tex]v = \frac{d(10) - d(2)}{8}[/tex] becomes

[tex]v = \frac{1300 - 52}{8}[/tex]

[tex]v = \frac{1248}{8}[/tex]

[tex]v = 156[/tex]

Hence, the average rate of change is 156ft/s

The system of equations for find b, the number of black-and-white copies, and c, the number of color copies that the customer paid for at the print shop is,

⇒ b + c = 68

⇒ 0.08b + 0.15c = 6

What is linear expression?

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.

Given that;

Total amount paid = $6.00

Total copies = 68

Cost of black-and-white copy = $0.08

Cost of color copy = $0.15

Now, Let number of black-and-white copies = b

And, Number of color copies = c

Hence, The equation become;

b + c = 68

0.08b + 0.15c = 6

Therefore, The system of equations for find b, the number of black-and-white copies, and c, the number of color copies that the customer paid for at the print shop is,

⇒ b + c = 68

⇒ 0.08b + 0.15c = $6
