A cheetah ran 300 ft. in 2.92 seconds. What was the cheetah's average speed in miles per hour? Show your work

vivado [14]

So, the cheetah's speed is 300/2.92 ft/sec

now, to convert it to miles/hr

well, there are 5280 ft in 1mile
and 60 minutes in 1hr
and 60 seconds in 1minute

so $\bf \cfrac{300\ f}{2.92\ s}\cdot \cfrac{1\ mi}{5280\ f}\cdot \cfrac{60\ min}{1\ hr}\cdot \cfrac{60\ sec}{1\ min}\\\\\\ \cfrac{300\cdot 1\cdot 60\cdot 60}{2.92\cdot 5280\cdot 1\cdot 1}\cdot \cfrac{f}{f}\cdot \cfrac{min}{min}\cdot \cfrac{sec}{sec}\cdot \cfrac{mi}{hr}$

Easiest way to calculate 22% mark up from a cost of say 39.99

satela [25.4K]

Answer:

The markup amount on the cost 39.99 $ will be: 8.78 $

Step-by-step explanation:

Given

The cost = 39.99 (Let say in $)

Mark up = 22%

As

22% = 0.22

The markup of 22% on the cost can be calculated by multiplying the cost by 22% or 0.22

so

Markup amount = 0.22 × 39.99

= 8.78 $

Therefore, the markup amount on the cost 39.99 $ will be: 8.78 $
