Point R is on line segment QS. Given QS = 16 and QR = 9, determine the length RS.

Answers

Answer:

The length RS = 7

Step-by-step explanation:

Here, we are interested in determining the length of RS

Let’s have the line segment arranged as follows;

Q R S

where QR = 9 and QS = 16

From the arrangement, we can deduce that;

QS = QR + RS

Thus;

RS = QS - QR

RS = 16 -9

RS = 7

Question 5 Rocko paid $12.50 for 25 game tickets. Louisa paid $17.50 for 35 game tickets. What is the constant of proportionality? Express your answer in decimal form.

Answers

Answer: k = $0.50

Step-by-step explanation:

The data that we have is:

Rocko paid: $12.50 for 25 tickets.

Louisa paid: $17.50 for 35 tickets.

Now, the question asks to find the constant of proportionality.

A proportional relation can be written as:

y = k*x

where k is the constant, and in this case, y is the price and x the number of tickets bought.

Then replacing with the values above, we have:

$12.50 = k*25

then:

k = $12.50/25 = $0.50

And the other data:

$17.50 = k*35

K = $17.50/35 = $0.50

So we have the same k in both cases, this means that the constant of proportionality is k = $0.50

the perimeter of a square can be found using P = n + n + n + n, where n is the length of one side of the square. Which equation could also be used to find the perimeter of a square

Answers

Answer:

P = 4n

Step-by-step explanation:

P = n + n + n + n

If you combine all the like terms you end up with:

P = 4n

The equation to find the perimeter of a square can also be expressed as 4n, where n is the side.

What is Square?

A square is a two dimensional figure which has four vertices, four sides and four angles.

Perimeter of a geometrical figure is the sum of the lengths of the boundary of shape.

Given that n is the length of one side of a square.

Perimeter is the sum of the side lengths.

Since a square has four sides,

Perimeter = 4 times the length of side

                 = 4n

Hence the perimeter of a square can also be expressed as 4n.
