Answer:

Step-by-step explanation:

x +x +2 + 38 = 180 {Angle sum property of triangle}

2x + 40 = 180

2x = 180 - 40

2x = 140

x = 140/2

A community center rents their hall for special events. They charge a fixed fee of $200 plus an hourly fee of $22.50. Lin has $300 to spend on renting the hall for a fundraiser.

Using only the money she has, can Lin pay for a 3 hour event? Explain or show your reasoning.
If LaTeX: hh represents the number of hours, what does LaTeX: 22.50h+20022.50 h + 200 represent?
Write and solve an equation to determine the number of hours Lin can rent the community center.
Write and solve an inequality that represents this situation. Explain what the solution to the inequality means in this situation.

Answers

Lin can only rent the hall for 4 hours with $300.

Linear equation

Linear equation is in the form:

y = mx + b

where y,x are variables, m is the rate of change and b is the initial value of y.

Let c represent the cost of renting the hall for h hours.

From the question, we get:

c = 22.5h + 200

If Lin has $330, hence:

300 = 22.5h + 200

h = 4.4 hours

Therefore Lin can only rent the hall for 4 hours with $300.

Item 20 You pay $4.35 for 0.75 pound of American cheese. You buy 2.5 pounds of Swiss cheese for $7.98 per pound. a. How much less does American cheese cost per pound than Swiss cheese? $ less per pound b. How much more do you spend on Swiss cheese than on American cheese? $

Answers

Answer:

a. $2.18

b. $15.60

Step-by-step explanation:

a. Price per pound of American cheese = $4.35 / 0.75 = $5.8

Price per pound of Swiss cheese = $7.98

Difference in price per pound = $7.98 - $5.8 = $2.18

b. Total amount spent on swiss cheese = $7.98 x 2.5 = $19.95

Amount spent more on Swiss cheese than on American cheese = $19,95 - $4.35 = $15.60

11. Jimmy bought some used video games and used movies at the Movie Barn. He bought a total of 15 items and spent $106 in all, not including tax. Each used video game cost $10 and each used movie
cost $6. How many of each item did he buy?

Answers

Answer:

Used Video game = x = 11

Used movie = y = 4

Step-by-step explanation:

Let

Used Video game = x

Used movie = y

x + y = 15 (1)

10x + 6y = 106 (2)

From 1

x = 15 - y

Substitute x = 15 - y into (2)

10x + 6y = 106

10(15 - y) + 6y = 106

150 - 10y + 6y = 106

-10y + 6y = 106 - 150

- 4y = -44

Divide both sides by -4

y = -44/-4

= 11

y = 11

Substitute y = 11 into (1)

x + y = 15

x + 11 = 15

x = 15 - 11

= 4

x = 4

Used Video game = x = 11

Used movie = y = 4

178.7 ft.

Step-by-step explanation:

The kite is (x + 5) ft above the ground. So we need to find x first.

Use the trigonometric identity Sine.

[tex]Sin\ \theta=\frac{perpendicular}{hypotenuse}\\\\sin44=\frac{x}{250} \\\\x=250*sin44\\x=250*0.69\\x=173.66\ ft\\[/tex]

Rounding your answer to the nearest tenth would be 173.7 ft.

Now the kite is above the ground x + 5 which means

173.7 + 5 = 178.7 ft.

A music club membership costs $15 to start and $8 per cd. Write an equation.

Answers

Answer:

y = 8x + 15

Step-by-step explanation:

Let x represent the number of cds, and let y represent the total cost.

Since each cd is $8, we can represent the extra cost from cds with the term 8x.

And, since the membership costs $15, this cost can be represented in the equation by +15.

Put these together:

y = 8x + 15 will be the equation representing this
