Divide 25.7 by 141.
Now, multiply that with 100 percent to get the percentage.
18.22% is your answer! If the question wants you to round it to the nearest percent, the answer will be 18%.
Time = distance / speed
Samma : 200/25.98 = 7.70 meters per second
Tom : 100 / 12.54 = 7.97 meters per second
so the faster runner is Tom
So the left side has a common denominator of 3. The 6x, -2x, and 8 can all go over a single 3. (6x-2x+8/3). Simplify the x's to get 4x. Now both sides have to be multiplied by 3 to get rid of that fraction. Then you just have 4x+8=24. Subtract 8 from both sides to get the x's alone, then divide both sides by 4 to get x alone. I have a picture to help.
Using translation concepts, we have that:
- The new equation is f(s) = (8/3)s - 20.
- The effect on the graph is that it is a vertical stretch by a factor of 2 of the function f(s).
- Selling 300 shirts with the new function, you obtain a profit of $780.
<h3>What is a translation?</h3>
A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
The profit function given in the problem is:
f(s) = (4/3)s - 20.
From this function, we get that the<u> profit with a single shirt sold is of $4/3</u>. To double the profit, this amount has to be multiplied by 2, hence the new function is:
f(s) = (8/3)s - 20.
Which is a vertical stretch by a factor of 2 of the graph of f(s).
When 300 shirts are sold, the profit is then given by:
f(300) = (8/3) x 300 - 20 = $780.
