No matter how long they rent for, they have to pay at least 20. Any additional hour is 10. But since it says “part of an hour” that makes this really easy.
1) $30 (the first hour is 20, the second hour is 10 even though they didn’t use the full hour completely)
2)$30 (same situation as 1)
3)$40 (20+10+10)
4)$50 (20+10+10+10 even though that additional hour was only 1 min)
5) Below five hours and above three hours. If you’re spending $50 you rented it within at least four hours. I hope that makes sense

A basketball team played six games. In those games, the team won by 9 points, lost by 18, won by
8, won by 11, lost by 3, and won by 5. What was the mean difference in game scores over the six
games?

Answers

Answer: 2

Step-by-step explanation:

From the question, we are informed that a basketball team played six games and that in those games, the team won by 9 points, lost by 18, won by 8, won by 11, lost by 3, and won by 5.

Thee mean difference in game scores over the six games will be calculated as the summation of the scores divided by 6. This. Will be:

= [9 + (-18) + 8 + 11 + (-3) + 5]/6

= 12/6

= 2

The mean difference in game scores over the six

games is; 2

We are given the points by which a basketball team either won or lost 6 games.

- Won by 9 points = +9

- Lost by 18 points = -18

- Won by 8 points = +8

- Won by 11 points = +11

- Lost by 3 points = -3

- Won by 5 points = +5

Thus;

Mean difference of the 6 games is;

(+9 - 18 + 8 + 11 - 3 + 5)/6

>> 12/6

>> 2

It costs $5 for an adult and $2 for a student to visit the National Botanical Gardens. Adults can be members of the Botanical society and can visit for free. A group of 30 adults and students visited the gardens. Five were members and it cost the group $104. How many students

Answers

Answer:

30 students!!!!?????

Answer: There are 2 students

Explanation: Each adult is equal to 5$ so If you divide 104$ by 5$ and only 20 numbers of 5 can fit in 104, and so your left with the number 4 and since each student it equal to 2 dollars that would mean 4 divided by 2, and the answer to that would be 2.

In the equation 6x - 2 = -4x + 2, Spencer claims that the
first step is to add 4x to both sides. Jeremiah claims that
the first step is to subtract 6x from both sides. Who is
correct? Explain.

Answers

Answer:

Spencer is correct

Step-by-step explanation:

Because adding 4x to each side will bring both numbers to a positive and that makes it easier to get the answer

Answer:

Sample Response: Both are correct. As long as inverse operations and the properties of equality are used properly, both methods will generate the same solution. They both isolate the variable on one side of the equation.

Step-by-step explanation:

10. A student solves the following problem:
Problem:
2 (x-3) + 3x = 19
2x - 6 + 3x = 19
(2x + 3x) - 6 = 19
5x - 6 - 19
Step 1
Step 2
Step 3
Step 4
Step 5
Step 6
5x - 6+ 6 = 19+ 6
5x = 25
X = 5
What property justifies step 4?
a. Commutative Property of Addition
c. Multiplication Property of Equality
b. Addition Property of Equality
d. Substitution

Answers

Answer:

Step-by-step explanation:

A.

Option A is correct. The property that justifies step 4 based on the calculation is the Commutative property of addition.

Equations are expressions separated by an equal sign.

Given the equation:

2(x-3) + 3x = 19

Expand the parenthesis using the distributive law

2x - 2(3) + 3x = 19

2x - 6 + 3x = 19

Collect the like terms

2x + 3x -6 = 19

Step 4

Since 2x+3x = 3x+2x = 5x (according to the commutative law), the expression becomes:

5x-6 = 19

Step 5

Add 6 to both sides

5x-6+6 = 19+6

5x = 25

x = 25/5

x = 5

Hence the property that justifies step 4 based on the calculation is the Commutative property of addition.

The measures of ∠x and ∠y are equal. X is 3(m+2) and Y is 5m-58. Which is the value of m? A m=8 B m=26 C m=30 D m=32

Answers

Answer with step-by-step explanation:

M = 32

Step 1: Simplify both sides of the equation.

3(m+2)=5m−58

(3)(m)+(3)(2)=5m+−58(Distribute)

3m+6=5m+−58

3m+6=5m−58

Step 2: Subtract 5m from both sides.

3m+6−5m=5m−58−5m

−2m+6=−58

Step 3: Subtract 6 from both sides.

−2m+6−6=−58−6

−2m=−64

Step 4: Divide both sides by -2.

−2m/−2=−64/−2

m=32

In 2010, Joe bought 200 shares in the Nikon corporation for $22.07 per share. In 2016 he sold the shares for $15.11each.
a. What was Joe's capital loss?
b. Express Joe's capital loss as a percent, rounded to the nearest percent.

Answers

Answer: a. $1392

b. 31.5%

Step-by-step explanation:

a. What was Joe's capital loss?

Cost price = $22.07 × 200 = $4414

Selling price = $15.11 × 200 = $3022

Capital loss = $3022 - $4414

= -$1392

b. Express Joe's capital loss as a percent, rounded to the nearest percent.

= Capital loss/Cost price × 100

= 1392/4414 × 100

= 31.5%

Answer:

a. $1392

b. 31.5%

Step-by-step explanation:

a. What was Joe's capital loss?

Cost price = $22.07 × 200 = $4414

Selling price = $15.11 × 200 = $3022

Capital loss = $3022 - $4414

= -$1392

b. Express Joe's capital loss as a percent, rounded to the nearest percent.

= Capital loss/Cost price × 100

= 1392/4414 × 100

= 31.5%

Find the distance between (4, -1) and (-2, -1). Round answer to the nearest tenth. *

Answers

Answer:

6

Step-by-step explanation:

You substitute the points into the distance formula. There aren't decimals in this answer, so I don't think you need to round to the nearest tenth. You can also check by plotting these points down on a graph.

(4, -1) (-2, -1)

The y coordinates are the same, you just need to count from -2 to 4. There are 2 steps before 0 and 4 steps after 0. So 2 + 4 is 6.

Answer:  6

===========================================

Work Shown:

[tex]\text{Distance Formula}\\\\d = \sqrt{(x_1-x_2)^2 + (y_1-y_2)^2}\\\\d = \sqrt{(4-(-2))^2 + (-1-(-1))^2}\\\\d = \sqrt{(4+2)^2 + (-1+1)^2}\\\\d = \sqrt{(6)^2 + (0)^2}\\\\d = \sqrt{36}\\\\d = 6\\\\[/tex]

This value is exact. No rounding is needed.

-------------

A shortcut is to subtract the x coordinates and apply absolute value

So either |x1-x2| = |4-(-2)| = |4+2| = |6| = 6

Or |x2-x1| = |-2-4| = |-6| = 6

This shortcut only works because the y coordinates the same for both points.

On a graph, you can plot the two points and count the spaces between them. You should count out 6 spaces.

length = 3x

width = x

24 ft = 3x + 3x + x + x

24 ft = 8x

3 ft = x

dimensions = length × width

= 3(3) × 3

= 9 ft × 3 ft

if you wanna check,

24 ft = 3(3) + 3(3) + 3 + 3

2) =========================

7 - (-7) = 7 + 7 = 14Option D)

3) =========================

8 + (-12) = 8 - 12 = - 4- 4 + 4 = 0Option A)

5) =========================

22 - 27 + 10 = 5Option B)

Answer:

1.) C

2.) C

3.) A

5.) B

Step by-step explanation:

1.) because 14 is positive and the opposite of 12 is -12. So 14+-12=2!

2.) to get to 7 from -7 you would have to take 7 units to get there.

3.)Given that a football player caught the ball and made a gain of 8 yards on the first play. On the next play the team lost 12 yards.we are to find the number of yards needed to gain on the next play to get back to their original position.Let, x be the number of yards that the team had originally.On the next play, the team lost 12 yards, let 'k' be the number of yards  needed to gain on the next play to get back to their original position.Thus, the number of yards needed to gain on the next play to get back to their original position is 4.

5.) We have been given that on Monday morning the temperature was 38°F, but by the afternoon the temperature had risen 22°F. We are also told that on Tuesday morning the temperature had dropped 27°F since Monday afternoon.Since the temperature rose  by the Tuesday noon, so temperature by Tuesday noon will be 10 degrees greater than temperature by Tuesday morning.To find the number of degrees temperature is above or below 38°F on Tuesday at noon we will subtract 38°F from the temperature on Tuesday at noon. Since the difference between temperature is positive, therefore, the temperature on Tuesday at noon was 5 above .
