Troy is considering two lawn care services. Premier Landscaping charges $15 for travel to Troy's house and $55 per hour for maintaining his lawn. Ace Landscaping does not have a travel fee, but charges $65 per hour for lawn maintenance. Part A Write a system of equations that represent the lawn care services.

Answers

Answer:

Cost for Premier Landscaping = [tex]55h+15[/tex]

Cost for Ace Landscaping = [tex]65h[/tex]

Where [tex]h[/tex] is the number of hours spent on lawn care.

Step-by-step explanation:

Given that:

Charges as per Premier Landscaping:

Fixed charges for travel to the house = $15

Per hour charges = $55

Let [tex]h[/tex] be the number of hours for which lawn care is done.

So, Charges for [tex]h[/tex] hours = Per hour charges [tex]\times[/tex] Number of hours =$55[tex]h[/tex]

Therefore, total cost = [tex]55h+15[/tex]

Charges as per Ace Landscaping:

Per hour charges = $65

Let [tex]h[/tex] be the number of hours for which lawn care is done.

Then Charges for [tex]h[/tex] hours = Per hour charges [tex]\times[/tex] Number of hours =$65[tex]h[/tex]

Therefore, system of equations that represent the lawn care services:

Cost for Premier Landscaping = [tex]55h+15[/tex]

Cost for Ace Landscaping = [tex]65h[/tex]

[tex]h>0[/tex]

Where [tex]h[/tex] is the number of hours spent on lawn care.

PLEASE help me!!! I need help with this problem below.... what is the rule for the sequence 1.8, 2.85, 3.90, 4.95, 6 Please answer this with a clear step by step explanation before tomorrow And help me out! Thanks!

Answers

Answer:

The next term is equal to the previous term with an added 1.05.

Step-by-step explanation:

The given sequence is:

1.8, 2.85, 3.90, 4.95, 6

The first term is:

[tex]a = 1.8[/tex]

The second term is:

[tex]a_2 = 2.85[/tex]

The third term is:

[tex]a_3 = 3.90[/tex]

The fourth term is:

[tex]a_4 = 4.95[/tex]

The fifth term is:

[tex]a_5 = 6[/tex]

Let us have a look at the difference of each term:

Second term - First term = 1.05

Third term - Second term = 1.05

Fourth term - Third term = 1.05

Fifth term - Fourth term = 1.05

We can see that there is a common difference between each term of the given sequence.

Therefore, we can conclude that:

The given sequence is an Arithmetic Progression which has the difference of each term as equal.

First term, [tex]a = 1.8[/tex]

Common difference, [tex]d =1.05[/tex]

So, the rule is:

The next term is equal to the previous term with an added 1.05.

What is the slope of the line represented by:

5x-12y = 24

Answers

Answer:

5/12

Step-by-step explanation:

5x - 12y = 24

~Subtract 5x to both sides

-12y = 24 - 5x

~Divide -12 to everything

y = -2 + 5/12x

~Reorder

y = 5/12x - 2

Slope is represent by "m" in slope intercept form [ y = mx + b ]. As we can see m = 5/12 from the given information.

Answers

Answer:

9

Step-by-step explanation:

Your ratio is 5 to 8

We know the total people in the class is 24 students. the total of the ratio (8) times 3 gives us 24! So, we also multiply the 5 by 3, which gives us 15. But its asking how many girls. If there are 15 girls, the rest are boys. So we subtract 24 by 15, which gives us 9

A college student goes to lunch at school and pays for lunch with her ID. Her mother put money into her account for her to do so, but she doesn’t know how much. ​Lunch is the same cost each day​ , but she doesn’t know what the cost is. After buying ​4 lunches​, she sees that her ​account balance is $91​ . After buying ​9 lunches​ , her ​balance is $67.25​ .

Answers

Each lunch would cost 4.75

Yes, the relationship is linear.

The cost of each lunch is $2.639.

The initial amount deposited by her mother is $101.55.

What is the slope?

The slope is the rate of change of the y-axis with respect to the x-axis.

The equation of a line in slope-intercept form is

y = mx + b, where

slope = m and y-intercept = b.

We know the greater the absolute value of a slope is the more steeper is it's graph or rate of change is large.

From the data itself, we can obtain two points to find the slope the points are

(4, 91) and (9, 67.25).

Slope(m) = (67.25 - 91)/(9 - 4).

Slope(m) = - 2.639.

The cost of each lunch is 2.639.

∴ 67.25 = -(2.639).9 + b.

b = 91.

∴ y = -(2.639)x + 91.

The initial amount put by her mother is 91 + 4(2.639) = $101.55
