Consider the line x-2y=-1 What is the slope of a line parallel to this line? What is the slope of a line perpendicular to this line?

Answers

Answer:

slope of line that is parallel is 1/2

slope of line that is perpendicular is -2

Step-by-step explanation:

parallel lines have the same slope

perpendicular lines have slopes that are opposite and reciprocal

x - 2y = -1

-2y = -x -1

y = 1/2x + 1/2

the coefficient of the 'x' term represents the slope

Annual sales for a fast food restaurant are $650,000 and are increasing at a rate of 4% per year. What is the annual sales after 7 years?

Answers

Answer:

Around $855,355.66

Step-by-step explanation:

In these type of problems, you'd use the following equation

[tex]Initial Value * (percentage)^{x}[/tex]

Since the revenue's increasing by 4% every year, you'd plug 104/100 in the percentage box. X is the ammount of times the percentage is applied, so it would be 7, since we're finding the sales after 7 years. Finally, 650000 goes into the initial value and yeah. After calculating, you'll get around $855,355.66

A store manager purchased hoodies for $24.99 apiece. He sells the hoodies for $32. What is the markup percentage?

Answers

Given:

A  store manager purchased hoodies for $24.99 apiece.

He sells the hoodies for $32.

To find:

The markup percentage.

Solution:

We have,

Cost price (C.P.) = $24.99

Selling price (S.P.) = $32

We know that,

[tex]\text{Markup percentage}=\dfrac{S.P.-C.P.}{C.P.}\times 100[/tex]

[tex]\text{Markup percentage}=\dfrac{32-24.99}{24.99}\times 100[/tex]

[tex]\text{Markup percentage}=\dfrac{7.01}{24.99}\times 100[/tex]

[tex]\text{Markup percentage}=\dfrac{701}{24.99}[/tex]

[tex]\text{Markup percentage}\approx 28.05[/tex]

Therefore, the markup percentage is 28.05%.

Stella is making 25 sundaes with mint, chocolate, and vanilla ice cream. 1 5 of the sundaes are mint ice cream and 1 2 of the remaining sundaes are chocolate. The rest will be vanilla. How many sundaes will be vanilla?

Answers

Answer:

Vanilla = 10 sundaes

Step-by-step explanation:

Total sundaes = 25

1/5 of the sundaes are mint ice cream

Mint ice cream = 1/5 of 25

= 1/5 * 25

= 25/5

= 5

Sundaes remaining = total sundaes - sundaes for mint ice cream

= 25 - 5

= 20 sundaes

Sundaes remaining = 20 sundaes

1/2 of the remaining sundaes are chocolate

= 1/2 of 20

= 1/2 * 20

= 20/2

= 10

Chocolate ice cream = 10

The rest will be vanilla

Sundaes remaining = 20 - 10

= 10 sundaes

Vanilla = 10 sundaes

find the value of 5m when m = -3

Answers

If m= -3, you would substitute -3 as m. So, 5(-3). Your answer would be -15!
When they give you the value for the variable, all you gotta do is to substitute it (Where you replace the variable/letter with the number it equals to).

So in this case, m = -3.

5m = 5(-3) = -15

A baseball team had 70 players show up for tryouts last year and this year had 85 players show up for tryouts. Find the percent increase in players from last year to this year.

Answers

Answer:percent increase in players from last year to this year= 7.14%

Step-by-step explanation:

percent increase = (Increase  in number of players /Initial value of players Last year)  x 100

value of players for tryouts  last year = 70

value of players for tryouts this year = 85

Increase in tryouts = 85-70 =5

percent increase = 5/70 x 100

= 7.14%

2. an=5n+1

3. an=21-5n

4. an=6n+1

Answers

Answer:

2)an = 5n + 1

Step-by-step explanation:

This is an arithmetic series.

6 , 11 , 16, 21 ,.....

First term = [tex]a_{1}[/tex] = 6

Common difference = d = second term - first term

                                = 11 - 6 = 5

nth term = [tex]a_{1}+(n-1)*d[/tex]

             = 6 + (n - 1) * 5

            =  6 + n * 5 - 1*5

            = 6 +5n - 5

           = 6 - 5 + 5n

           = 1 + 5n
