Answer:
Jamal travels at a speed of 5 mph and Diego travels at a speed of 12 mph.
Step-by-step explanation:
Jamal's speed is of x mph.
Diego's speed is of (x + 7) mph.
Opposite directions.
This means that each hour, they will be x + x + 7 = 2x + 7 miles apart.
After 4 hours they are 68 miles apart, how fast is each traveling?
Using a rule of three.
1 hour - 2x + 7 miles apart.
4 hours - 68 miles apart.
![4(2x + 7) = 68](https://tex.z-dn.net/?f=4%282x%20%2B%207%29%20%3D%2068)
![8x + 28 = 68](https://tex.z-dn.net/?f=8x%20%2B%2028%20%3D%2068)
![8x = 40](https://tex.z-dn.net/?f=8x%20%3D%2040)
![x = \frac{40}{8}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B40%7D%7B8%7D)
![x = 5](https://tex.z-dn.net/?f=x%20%3D%205)
Jamal travels at a speed of 5 mph and Diego travels at a speed of 12 mph.
1. it says no more than 5 so that includes 5, so there are 5/8 probability
2.since this spinner stops on an even number (8) that means half are even and half are odd so 4/8, but you can reduce that to 1/2
3.since it says less than 3 there are only two so that ends up being 2/8 or 1/4 probability
The answer is 13.0 for the distance between Samantha and Mia after 1 hour.
Answer:
Well, the correct answer is 119.<u>4347826086956521739130</u> (after the 130 the whole decimal is repeated.
Step-by-step explanation:
Although if your assignment is asking for an estimate you could probably just say 119 since the first and second decimal is less then 5
