Change the fraction 1/5 to a percent
2 answers:
To write a fraction as a percent, first remember that a percent is a ratio of a number to 100. If we wanted to write as a percent, we need to find a fraction equivalent to
that has a 100 in the denominator. We can do this by setting up a proportion.

Now, we can use cross products to find the missing value.

<h2> P = 98 cm</h2>Step-by-step explanation:
Given one side and diagonal of rectangle we can use Pythagorean theorem to calculate the other side of it.
Perimeter:
P = 2W + 2L = 2•40 + 2•9 = 80 + 18 = 98
Answer:
S'(x)=-0.006x2+0.8x+9
Step-by-step explanation:
The rate of change of the sales S(x) with respect to the amount of money spent on advertising x is then the derivative of S(x) with respect to x. What we have to calculate is S'(x).
We know that the derivative of is
(where a is a constant), and the derivative of a sum is the sum of the derivatives, so we can calculate the derivative of each term independently:
S'(x)=(−0.002x3 + 0.4x2 + 9x + 500)'=(−0.002)(3)x2 + (0.4)(2)x + 9
Which means:
S'(x)=-0.006x2+0.8x+9
