⇒The answer to the first question would be $69.75.

⇒The answer to the 2nd question would be $36.48.

⇒The answer to the 3rd question would be $42.7.

Here's how to get them:

For question 1: A 55% markup for $45 ⇒1.55*45⇒69.75

For question 2: A 60% markup for $22.8⇒ 1.6*22.8⇒36.48

For question 3: A 40% markup for $30.50⇒1.4*30.50⇒42.7

Small Explanation: The reason why there should be a 1 in front of the decimal (which is the percent, but in decimal form) is because by not adding that number 1 in front of the decimal, you will have to do an extra step.

Anyway, hope this helped! :-)

Answer:

A= $40584.28

Step-by-step explanation:

P = 36000

r = 12% = 0.12

n = 52 weeks

t = 1

$A = P(1 + \frac{r}{n})^{nt}\\$

$=36000(1 + \frac{0.12}{52})^{52 \times 1}\\\\=36000 (1.002307)^{52}\\\\=36000 \times 1.12734\\\\=40584.28$

If anyone knows the answer to these can u please help? thank you! :)

Answers:

A) Ray QS or Ray QR
B) Line segment QS or SQ
C) Plane QSR
D) Line QS or RQ

=======================================================

Explanation:

Part A)

When naming a ray, always start at the endpoint. This is the first letter and we'll start with point Q.

The second letter is the point that is on the ray where the ray aims at. We have two choices S and R as they are both on the same ray. That's why we can name this Ray QS and Ray QR.

--------------------

Part B)

A segment is named by its endpoints. The order of the endpoints doesn't matter so that's why segment QS is the same as segment SQ. To me, it seems more natural to read from left to right, so QS seems better fitting (again the order doesn't matter).

--------------------

Part C)

When forming a plane, you need 3 noncollinear points. The term "collinear" means the points all fall on the same line. So these three points cannot all fall on the same straight line. In other words, we must be able to form a triangle of some sort.

So that's how we get the name "Plane QSR". The order of the letters doesn't matter.

--------------------

Part D)

To name a line, we just need to pick two points from it. Any two will do. The order doesn't matter. So that's how we get Line QS and Line RQ as two aliases for this same line. It turns out that there are 6 different ways to name this line.

Line QR
Line QS
Line RQ
Line RS
Line SQ
Line SR
