Answer:

22 2/3

Step-by-step explanation:

Each student has 1 1/3 minutes to speak. There are 17 students.

1 1/3 x 17= 17 17/3

3 goes into 17 5 times and leaves behind 2 and so you combine the 5 and 17 making 22. the 2 left behind remains as the fraction 2/3

The center on a target has a diameter of 5 inches. The whole target has a diameter of 25 inches. The center of the target takes

Komok [63]

4%

To find the percentage, first find the area of both circles. The area formula is $\pi r^{2}$ . After finding the area of the center of the target (19.625) and the area of the large target (490.625), set up a percent proportion to determine the percentage that the center takes up:

$\frac{is}{of} = \frac{percent}{100}$

$\frac{19.625}{490.625} = \frac{percent}{100}$

Cross multiplying and dividing by 490.625 will give a total of 4%.
