Answer 1

The answer is 4 so B

Answer 2

Answer:

B. 4

Step-by-step explanation:

Create an equation:

80 = 18x+8

Solve for x by subtracting both sides by 8:

80-8 = 18x+8-8

72 = 18x

Divide both sides by 18:

72/18 = 18x/18

4 = x

If both of them are vertical angles, they equal each other. 2x+19=5x-5 is how you would set it up. Add 5 to 19 to get 24 and subtract 2x from 5x to get 3x. 3x=24, so x=8. If you plug that in, your angles should be 35 degrees for each.

Answer:

x=8

Step-by-step explanation

Vertical angles are always congruent which means they are equal

Since we know this we can simply set the two angle equal to each other so...

5x-5=2x+19

Now what we do is add five to 19 and subtract 2x from 5x to get

3x=24

simply divide 24 by 3 to isolate x and now we have

x=8

Work out the cost of 12kg of potatoes and 1 1/2kg of carrots

Answers

Answer:

The cost is #15.90

Step-by-step explanation:

See comment for complete question

Given

[tex]P \to Potato[/tex]

[tex]C \to Carrot[/tex]

[tex]3P + 2C = 5.08[/tex]

[tex]P = 1.24[/tex]

Required

[tex]12P + 1\frac{1}{2}C = ??[/tex]

First, we solve for C

Substitute [tex]P = 1.24[/tex] in [tex]3P + 2C = 5.08[/tex]

[tex]3 * 1.24 + 2C = 5.08[/tex]

[tex]3.72 + 2C = 5.08[/tex]

Collect like terms

[tex]2C = 5.08 - 3.72[/tex]

[tex]2C = 1.36[/tex]

Solve for C

[tex]C = \frac{1.36}{2}[/tex]

[tex]C = 0.68[/tex]

So, we have:

[tex]P = 1.24[/tex]

[tex]C = 0.68[/tex]

[tex]12P + 1\frac{1}{2}C = ??[/tex] becomes

[tex]12P + 1\frac{1}{2}C = 12*1.24 + 1\frac{1}{2}*0.68[/tex]

[tex]12P + 1\frac{1}{2}C = 14.88 + 1.02[/tex]

[tex]12P + 1\frac{1}{2}C = 15.90[/tex]

Lisa plays soccer 3 out of the 7 days of the week. How many possible schedules are there to play
soccer on Monday or Tuesday or both.
Ex: 5

Answers

Answer:

There are 25 possible schedules.

Step-by-step explanation:

The order in which they play soccer is not important(Monday and Tuesday is the same as Tuesday and Monday), and thus the combinations formula is used to solve this question.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

Monday but not Tuesday:

Monday(1) and 2 out of the remaining 7 - 2 = 5. So

[tex]C_{5,2} = \frac{5!}{2!3!} = 10[/tex]

Tuesday but not Monday:

Tuesday(1) and 2 out of the remaining 7 - 2 = 5. So

[tex]C_{5,2} = \frac{5!}{2!3!} = 10[/tex]

Monday and Tuesday:

Monday and Tuesday(1), plus one out of the remaing 5 days. So

[tex]C_{5,1} = \frac{5!}{1!4!} = 5[/tex]

Total:

10 + 10 + 5 = 25

There are 25 possible schedules.

Consider a market with two firms, Hewlett-Packard (HP) and Dell, that sell printers. Both companies must choose whether to charge a high price ($) or a low price ($) for their printers. These price strategies with corresponding profits are depicted in the payoff matrixLOADING... to the right. HP's profits are in red and Dell's are in blue. Suppose HP and Dell are initially at the game's Nash equilibrium. Then, HP and Dell advertise that they will match any lower price of their competitors. For example, if HP charges $, then Dell will match that price and also charge $. What effect will matching prices have on profits (relative to the Nash equilibrium without price matching)?
