It would be take upto 999 revolutions.
<em>Let try to solve it,</em>
Let n represent number of revolutions.
We are asked to find the number of revolutions it will take for a car wheel of diameter 30 in. to travel a distance of one mile.
1 mile = 63360 inches.
We will use circumference of circle formula to solve our given problem.
Circumference = pi*d , where, D represents diameter of circle.
Now, we will set the product of n and circumference of circle equal to 63360 inches as:
pi*22*n= 63360
n= 63360*7/ 22*22
n= 443520/444
n= 998.91
Therefore It would be take upto 999 revolutions.

Answer:
<h2>Your Answer is 32%</h2>
Explaination:
<em>We already have our first value 75 and the second value 24. Let's assume the unknown value is Y which answer we will find out.</em>
<em>We already have our first value 75 and the second value 24. Let's assume the unknown value is Y which answer we will find out.As we have all the required values we need, Now we can put them in a simple mathematical formula as below:</em>
<em><u>STEP 1 </u>>> Y = <u>2</u><u>4</u></em>
<em> </em><em> </em><em> </em><em> </em><em> </em><em>75</em>
<em><u>STEP 2</u> >> </em><em> </em>
<em> </em>
<em><u>24</u><u> </u> × <u>10</u><u>0</u></em><em> </em><em> </em><em> </em><em> </em><em>=</em><em> </em><em> </em><u><em>3</em><em>2</em></u>
<em>7</em><em>5</em><em> </em><em> </em><em>× 100</em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>1</em><em>0</em><em>0</em>
<em><u>STEP 3</u>>> Y = 32</em><em>%</em>
<em>Finally, we have found the value of Y which is 32 and that is our answer.</em>
<em>You can use a calculator to find what percent of 75 is 24, just enter 24 ÷ 75 × 100 and you will get your answer which is 32</em><em>.</em>
Answer:
Correct answer is : $220
Step-by-step explanation:
Here, cost price = $66
Let the selling price be $x.
According to the statement given in problem,
Selling price - cost price = 70% of selling price
i.e. x - 66 = 70% * x
x - 70x/100 = 66
30x / 100 = 66
x = 6600 / 30 = $220
i.e Selling price = $220
Answer:
2 11/12
Step-by-step explanation:
total amount fred used = 1/3 x 7 = 7/3
total amount Janice used = 1/4 x 7 = 7/4
total amount used =
7/3 + 7/4
(28 + 21) / 12 = 49 / 12 = 4 1/12
Amount left = 7 - 4 1/12 = 2 11/12
