Answer:
1st option is correct .........
Answer:
15) For a regular polygon of N sides, the measure of one interior angle is:
A = (N - 2)*180°/N
In this case, the figure has 11 sides, then we have N = 11, and the measure of each interior angle will be:
A = (11 - 2)*180°/11
A = 9*180°/11 = 147.27°
Rounding to the first decimal after the decimal point, we get:
A = 147.3°
Then the correct option is B.
16) We know that the length of all the sides of a square is the same.
In the image, we can see that the length of the right side is 4, and the length of the top side is 2x + 4
And those lengths must be the same, then we have the equation:
2x + 4 = 4
subtracting 4 in each side of the equation we get:
2x + 4 - 4 = 4 - 4
2x = 0
The only solution for this equation is x = 0.
Then the correct option is C
To solve this problem you must apply the proccedure shown below:
1. You have the following information given in the problem above:
- The distance is
.
- The time is
.
2. Therefore, you must divide the distance by the time to calculate the average speed:
![V=d/t\\ V=112miles/12hours\\ V=9.33 miles/hour](https://tex.z-dn.net/?f=%20V%3Dd%2Ft%5C%5C%20V%3D112miles%2F12hours%5C%5C%20V%3D9.33%20miles%2Fhour%20)
The answer is: ![9.33miles/hour](https://tex.z-dn.net/?f=%209.33miles%2Fhour%20)
