The radius of the circle is 35 cm
Step-by-step explanation:
One revolution of the wheel of a cart = the length of the circumference of the wheel
Let the radius of the wheel be r cm
The circumference = 2 X pi X r
In 5000 revolutions the wheel covers 2 X pi X r X 5000 cm
According to the problem,
2 X pi X r X 5000 = 11 X 1000 X 100
or, pi X r = (11 X 1000 X 100)/(2 X 5000)
or, r = 110 / pi
or, r = (110 X 7)/22
= 35
Here is the answer.
Answer:
Definitely start with outlining one essay, then doing all of your steps, although don't do much re-writing since there may not be enough time. only focus on one at a time though. as for the questions, since it says pre-essay it wants that completed first but unless you have to do it first, i would do it last since the essays are more important.
Answer:
51 minutes!
Step-by-step explanation:
<em>Hello there fellow human!</em>
First off, you convert kilometers to miles.
1 kilometer = 0.62 miles; therefore, 8 kilometers = 8*0.62 = 4.96 miles
Next, you determine how many minutes it takes for John to cover 1 mile
which is gotten by dividing 41 by 4;
41 / 4 = 10.25. So it takes 10.25 minutes to cover 1 mile. (minutes per mile)
Next, you multiply the number of minutes taken to cover <em>1 mile (10.25)</em> by <em>4.96 miles (8 kilometers)</em>, 10.25 * 4.96 = 50.84 minutes. Rounding that to the nearest minute, you get 51 minutes which make sense because the amount of time taken to cover 4 miles (41 minutes) will be shorter than the time taken to cover 4.96 miles (50.84 minutes) since 4 miles is smaller than 4.96 miles.

All calculations where done with a calculator. If you don't have that, you can always divide manually and convert to fraction.
So... Emily gets payed 12 dollars for every hour she works. with and ADDitional 30 dollars by the end of her day. Therefore you would multiply her hourly income (12) by the amount of hours she works (h). Then, add her 30 dollars to it. (Im feeling nice so the answer should look like this ~ 12h + 30.) Hope it helps you <3!
