Answer:
x = 72
Step-by-step explanation:
For all polygons, the exterior angles add up to 360°
Since a pentagon has 5 exterior angles, you do
angle = 360 ÷ 5 = 72

Answer: 106
Step-by-step explanation:
First, we can subtract 182.90 from 750, and then divide the answer by 5.35.
750 - 182.90 = 567.10. Mrs. Canale's class still needs to earn 567.10 dollars.
Now we can divide 567.10 by 5.35 to find how many frozen pizzas the class has to sell.
567.10 / 5.35 = 106.
Therefore, Mrs. Canale's class will still need to sell 106 frozen pizzas to meet their $750 goal.
Answer:
6mph
Step-by-step explanation:
In this question, we are asked to calculate the speed at which Carol jogs, given that she has a particular speed when she jogs greater than when she walks.
Firstly, we should understand that she is taking the same distance, whether she jogs or walks.
Now, let’s say her jogging rate is x mph, this means that her walking rate would be (x - 4)mph. This is because her jogging rate is 4mph faster than her walking rate.
The total distance covered when jogging is thus 10/60 * x, while her total distance covered when walking would be 30/60 * (x-4)[we convert the time to hours]
We equate both since they are same distance:
x/6 = (x -4)/2
2x = 6(x - 4)
2x = 6x - 24
4x = 24
x = 6mph
