Troyanec [42]

An equation that models the proportional relationship between t and s.

t = 12.5s

<h3>What is proportional relationship?</h3>

Relationships between two variables where their ratios are equal are known as proportional relationships. The fact that one variable is always a constant value multiplied by the other in a proportionate connection is another way to conceive of them. This parameter is referred to as the "constant of proportionality."

<h3>According to the given information :</h3>

1) Ticket for an art museum costs $12.50

2) In other words, the price will increase by $12.50 for each ticket purchased (or tickets).

In other words, the total expense is always 12.5 times the quantity of tickets sold.

3) This indicates that we can create this ---> t = 12.5s.

An equation that models the proportional relationship between t and s.

To solve a one-step equation, you must _____<br> the variable.
krek1111 [17]

Answer:

Isolate.

Step-by-step explanation:

To solve a one-step equation, you must isolate the variable.

For example,

3x = 9.

You must isolate x, which just means you have to get x by itself.

Divide by 3 on both sides to get x by itself.

x = 3.

The answer to this question is isolate.

Which of the following sets of points are vertices of a right triangle?
grandymaker [24]

  • Please find the picture for your triangle.
  • We know, area of a ∆ = <u>1/2 × base × height</u>
  • Here, base = ( 1 + 7 ) units = <u>8 units</u>
  • Height = ( 7 - 1 ) units = <u>6 units</u>
  • Therefore, area of the ∆
  • = <u>(1/2 × 8 × 6) square units</u>
  • = <u>24 square units.</u>

<u>Answer</u><u>:</u>

<em><u>2</u><u>4</u><u> </u><u>square </u></em><em><u>units</u></em>

Hope you can get an idea from it.
