Answer:
I don't know for sure, but there are a bunch of different options. Here they are:
Step-by-step explanation:
1 + 39
2 + 38
3 + 37
4 + 36
5 + 35
6 + 34
7 + 33
8 + 32
9 + 31
10 + 30
11 + 29
12 + 28
13 + 27
14 + 26
15 + 25
16 + 24
17 + 23
18 + 22
19 + 21
20 + 20
Those are the options of how many volcanoes that they could have visited. They could have visited 23 volcanoes in Alaska and 17 in California. Who knows?
California only has 20 volcanoes, and Alaska has 40, so your answer will be one of these options. Hope this helps!
The distance between Car A and car B,When Car A crosses the start line is:
distance =speed car B* time
distance=(15 m/s)(3 s)=45 m
Distance traveled by car A =x, (when the car B is at the same distance from the start line)
time of car A=t
x=10 m/st ⇒ x=10t (1)
Distance traveled by car B=x
time of car B=t-3
x=15(t-3) (2)
With the equations (1) and (2) we make a system of equations:
x=10t
x=15(t-3)
We solve this system of equations:
10t=15(t-3)
10t=15t-45
-5t=-45
t=-45 / -5
t=9
t-3=9-3=6
x=10 t=10 (9)=90
Answer: The time would be 9 seconds for Car A and 6 seconds for car B and the distance would be 90 meters.
If it goes from a higher number to a lower number it is a decrease.
(15,295 - 9182) / 15295....x 100
6113 / 15295 = 0.399....x 100 = 39.9% decrease
