Answer:

C

Step-by-step explanation:

The percent markup is basically how much it is MORE than the original.

First, we need to find how much the selling price is more than cost.

Cost = 22.99

Selling Price = 36.99

Markup = 36.99 - 22.99 = $14

How much is the markup, we just found, with respect to cost? That is the markup divided by cost, multiplied by 100 [to convert to percentage]. Shown below:

\frac{14}{22.99}*100=60.9

So, the percent markup = 60.9%

Answer choice C is right.

gayaneshka [121]

Answer:

20 cm

Step-by-step explanation:

Since it is a rectangle, we know that there are two pairs of sides the same length. All we have to do is add each number by itself, and add those numbers together, or you can envision it like this graph I made.

4+4=8

6+6=12

8+12=20

A projectile is fired at time t = 0.0 s, from point 0 at the edge of a cliff, with initial velocity components of V ax= 50m/s an
Kruka [31]

The projectile has constant horizontal speed all the time and we can use this formula

x=Vax*t, where t is time it (projectile) takes to reach x=1000m

t=x/Vax=1000/50=20s

As we know we can split projectile trajectory in two parts and the time for each part is equal. We can conclude that time t=20s belong to first part where projectile is going up.

Formula for this type of movement is  y=Vay-(gt∧2)/2

If we take acceleration of gravity g=10m/s∧2

we get     y=200*20-(10*20∧2)/2=4000-2000=2000m

But if I calculate time it takes the highest point I get  

t=Vay/g=200/10=20s

The highest point for that time is

y= H=Vay∧2/2g=200∧2/2*10=40000/20=2000m

This happened because the projecile is fired from the edge of a cliff which is above the sea line.

Good luck!!!
