A local gym charges nonmembers $10 per hour to use the tennis courts. Members pay a yearly fee of $300 and $4 per hour for using the tennis courts. Write and solve an equation to find how many hours you must use the tennis courts to justify becoming a member.

Answers

Nonmembers: $10 per hour = 10h
Members: $300 and $4 per hour = 300 + 4h

10h > 300 + 4h
6h > 300
h > 50

You'd need to use it for more than 50 hours.

Answer:

75 Hours

Step-by-step explanation:

75h x $4 = $300

You would need 75 hours to justify the $300 fee

A plot of land is about 13,000 ft by 8000 ft. Approximately how many square miles is this? Round to the nearest whole number.

Answers

5280ft = 1mile

13,000ft = 2.46miles 8,000ft = 1.52 miles

2.46 x 1.52 = 3.7 miles^2

Answer:

4 square miles

Step-by-step explanation:

A plot of land is about 13,000 ft by 8000 ft.

1 mile = 5280 ft

To convert feet to miles we divide by 5280

13000 ft = [tex]\frac{13000}{5280}=2.4621[/tex]

8000 ft = [tex]\frac{8000}{5280}=1.5152[/tex]

Now we find the area

To find area we multiply the miles

2.4621* 1.5152= 3.73057392

When we round to nearest whole number it becomes

4 square miles

What is the perimeter of trapezoid JKLM?

+ units
2 + + units
9 + units
9 + + units

answer is D

Answers

For the perimiter of the trapezoid you need the length of all four sides, and as the left and right sides are diagonal you use the pythagorean thereom to solve for them. This theorem is a^2+b^2=c^2 as a is vertical, b is horizontal, and c is the diagonal. so for the right side we have 1^2+2^2=c^2 so c^2=5 and c=sqrt(5). for the left side we have 1^2 + 1^2 = c^2 so c = sqrt(2) so we take the top, 3, the bottom, 6, and the sides, sqrt(2) and 5, and add them to get 9 + sqrt(2) + sqrt(5) so D

Perimeter is the sum of the length of the sides used to make the given figure. The correct option is D.

What is the perimeter?

Perimeter is the sum of the length of the sides used to make the given figure.

The length of the different sides of the trapezoid can be written as,

JK = 3 units

KL = √(2² + 1²) = √5 units

LM = 6 units

JM = √(1² + 1²) = √2 units

Now, the perimeter of the trapezoid JKLM is,

Perimeter JKLM = 3 + √5 + 6 + √2 = (9 + √5 + √2) units

Hence, the perimeter of the trapezoid JKLM is (9 + √5 + √2) units.

5.4 = a - (-1.8) solve for a.

Answers

subtracting a negative cancels them to become positve so now we have a + 1.8 = 5.4.

subtract 1.8 from both sides of a + 1.8 = 5.4 to isolate the variable and we have:
a = 3.6 because 5.4 - 1.8 is 3.6.

therefore a = 3.6. hope this helped! plug it into the original equation and you see that you get 5.4 = 5.4

Vertical Angles: 2x - 20 = x + 15
Solve for x, you get that x = 35.
Therefore, the answer is A)35°. Hope this helps and have a phenomenal day!

Answer:

a) 35°

Step-by-step explanation:

Vertical angles are the opposite angles that form when two lines intersect.

The vertical angles are equal.

1. As vertical angles are equal first take the values of the two angles and put them in an equality as follows:

[tex]2x-20=x+15[/tex]

2. Then, solve for x:

[tex]2x-x=15+20[/tex]

[tex]x=35[/tex]°

Therefore the angle MHJ is 35°

A clothing store is running a special in which customers receive a free pair of jeans with the purchase of 4 shirts. It costs the clothing company $3.46 to produce one shirt and $5.56 to produce one pair of jeans. The store is selling each shirt for $21.46. Approximately how much money will the company make if 42 customers take advantage of the special?

Answers

Final answer:

The clothing company will make approximately $214.60 if 42 customers take advantage of the special.

Explanation:

To calculate the amount of money the company will make, we need to determine the total cost of shirts and jeans given out for free.

Each customer will receive a free pair of jeans for every 4 shirts purchased.

The cost of 1 shirt is $3.46 and the cost of 1 pair of jeans is $5.56.

So, the cost of 4 shirts is 4 x $3.46 = $13.84.

Therefore, for each set of 4 shirts, the company is losing $13.84 on production costs and gaining $21.46 on sales.

For 42 customers, the company will distribute 10 sets of 4 shirts and give away 10 pairs of jeans.

The total amount of money the company will make is (10 x $21.46) = $214.60.

I don't know what the symbol means or what to do.

Answers

Answer:

Step-by-step explanation:

That weird symbol means "element". In our case, the elements of the domain (the x-values) are -15, -6, -1. Which tells us that we are going to sub each one of the numbers into the equation and solve it for the corresponding y value. That in turn gives us the coordinate point. The equation is

x + y = 6

Subbing in first -15 for x:

-15 + y = 6 and

y = 6 + 15 so

y = 21 and the coordinate point is (-15, 21).

Subbing in -6 for x:

-6 + y = 6 and

y = 6 + 6 so

y = 12 and the coordinate point is (-6, 12).

Subbing in -1 for x:

-1 + y = 6 and

y = 6 + 1 so

y = 7 and the coordinate point is (-1, 7)

The second choice is the one you want.

Just remember that x is the domain and any elements in the domain go in for x.

Also remember that y is the range and any elements in the range go in for y

Answers

Because of the Vertical Angle Theorem, you know both angles are congruent. Therefore, 1/4x+3=3/4x-7. Solving for x, x=20, and the angle measure is 8 degrees.

They're equivalent to each other so write it out so they equal each other. Then subtract 3 from both sides and u get 1/4x = 3/4x - 10. After that you subtract 3/4 from both sides and u get -2/4x = -10. Now u divide both sides by -2/4 (or -1/2). and get x =20.
