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:

<em>Charges as per Premier Landscaping:</em>

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.

Mom and Dad have four daughters, and each daughter has one brother. How many people are in the family?

7. If each sister has one brother, it would be one brother total, because they are all related. They don't each have their own brother. So mom+dad+sisters(4)+brother=7 total.

9. Let p be "an animal is a dog" and let q be "an animal is a golden retriever." Write the conditional statement.

pychu [463]

Answer:

C. If an animal is a dog, then it is a golden retriever; false

Step-by-step explanation:

Logical reasoning is an important aspect of mathematics.

The conditional statements in the question are represented by the letters p and q. The if-then statement in which the statement p will lead to a conclusion in q is a glaring characteristic of conditional statements. A conditional will be held to be true unless a statement that is true has a false conclusion derived from it.

In the question above, the conditional statement is; If an animal is a dog, then it is a golden retriever. We can clearly see that this conclusion is false.
