Troy is considering two lawn care services. Premier Landscaping charges $15 for travel to Troy's house and $55 per hour for main

Irina18 [472]

Answer:

Cost for Premier Landscaping = $55h+15$

Cost for Ace Landscaping = $65h$

Where $h$ 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 $h$ be the number of hours for which lawn care is done.

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

Therefore, total cost = $55h+15$

Charges as per Ace Landscaping:

Per hour charges = $65

Let $h$ be the number of hours for which lawn care is done.

Then Charges for $h$ hours = Per hour charges $\times$ Number of hours =$65 $h$

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

Cost for Premier Landscaping = $55h+15$

Cost for Ace Landscaping = $65h$

$h>0$

Where $h$ is the number of hours spent on lawn care.

A baseball stadium holds 15,002 seats. The lower level has 50 fewer than three times as many seats as the upper

Elanso [62]

Answer:

B) The equation x + (2 x + 40) + (3 x - 50) = 15,002 represents this scenario suitable.

Step-by-step explanation:

Let x represent the number of upper-level seats.

Total seats in stadium = 15,002

Now, seats in the lower level = 3 ( Seats in upper level ) - 50

= 3x - 50

or, the total seats in the lower level = (3 x - 50)

Also, seats in the middle level = 2 ( Seats in upper level ) + 40

= 2x + 40

or, the total seats in the middle level = (2 x + 40)

Now, according to question

Upper Level seats + Middle level seats + Lower level = Total seats

⇒ (x) + (2 x + 40) + (3 x - 50) = 15,002 seats

Hence, the equation x + (2 x + 40) + (3 x - 50) = 15,002 represents this scenario suitable.

Answer

square root of 32

Step-by-step explanation:

in a right triangle we can use Pythagorean theorem to find B

$C^{2} =A^{2}+B^{2} \\\\ 9^{2}=7^{2}+B^{2} \\81=49+B^{2} \\81-49=B^{2} 32=B^{2}\\ B=\sqrt{32}$ we substitute C for 9 and A for 7
