Answer: 4.02 c

Step-by-step explanation:

so the area of a circle is equal to A=pi multiplied by the radius to the second power. And since that’s half a circle it would make sense for the area to be half of the full circle. The radius (half of the diameter and the area from the center of the circle to the outer edge.) is shown as 1.6ft, 1.6^2 is 2.56 and multiplied by pi that is 8.04 half of that is 4.02.

We're not supposed to help with exams. This isn't an exam, is it?

A(0)=202, A(37)=half that.

$A(t) = 202 (\frac 1 2)^{t/37}$

$A(100) = 202 (\frac 1 2)^{100/37} \approx 31.0$

The product of two rational numbers is 9⁄7 and one of them is 15⁄14. Then the other rational number is

Rasek [7]

Answer:

The other rational number in the operation given is:

<u>6/5</u>

Step-by-step explanation:

To obtain the number in the operation given, we're gonna represent the operation:

r * 15/14 = 9/7

Where:

r = the other rational number.

Now we are going to solve r to identify its value in numbers:

r * 15/14 = 9/7

$r = \frac{\frac{9}{7} }{\frac{15}{14}}$ (We pass a number that is multiplying to the left of the equal, to divide to the right of the equal symbol)

$r = \frac{6}{5}$

As you can see, when we operate, <u>the result is 6/5</u>, and we can prove this multiplying as we had in the original equation, replacing r by 6/5:
