Answer:
9
Step-by-step explanation:
Equation
Sum = s = 180*(n - 2)
Solution
1260 = 180*(n - 2) Divide by 180
1260 / 180 = 180 * (n -2 ) / 180
7 = n - 2 Add 2 to both sides
9 = n
Answer
The polygon has 9 sides.
Average speed = Total distance/Time
A = 550km/6.5hr
A = 84.6 km per hr
Answer:
$5.4 Million
Step-by-step explanation:
3.2 mill/x = 60/100
3.2 mill x 100 = 60x
320 mill = 60x
x = 5.3333 million, rounded up to 5.4 million
In order to find a percentage, you divide the sample by the total amount.
For example: Tess has 3 cookies out of the total amount of 9. 3/9 = 33.3%
Answer:
Step-by-step explanation:
- cotx cos x - cot x = 0
- cotx( cosx - 1) = 0
1. <u>cotx = 0</u>
- x = π/2 + πn
- In the interval [0, 2π] we have π/2 and 3π/2
2. <u>cosx = 1</u>
- x = 0 + 2πn
- In the given interval we have 0 and 2π
<u>So the solution set is:</u>
