Answer: He would have traveled 248 miles
Explanation: This is a ratio
To find how many miles he would have traveled after 4 hours, we need to apply the information givin into a ration table
(We can put miles on the top and hours on the bottom)
217 ?
------- ------
3.5 4
Now, we can do two things:
1. cross multiply
we would take 217 times 4 (868) and divide that by 3.5 (248)
2. Divide the top and bottom by 3.5 (numerator= 62 denominator= 1)
multiply 62 by 4 to get 248
Hope this helps!
Answer:
c
Step-by-step explanation:
<BAC = <DEC = 30°
<BCA = <DCE = 70°
<CDE (or m<D) = 180° - <DEC - <DCE
<CDE = 180° - 30° - 70°
<CDE = 80°
The number that belongs in the green box is 80
