If 3 is the number missed, we want the percentage wrong
3(100)=10(x)
10x=300
Divide by 10
x=30
Answer:
60mph
Step-by-step explanation:
Let d be the distance. Let v be the speed of car a. That means the speed of car b is v + 15. Now we can set up 2 equations using the v = d/t:
Car a: v = d / 2 --> d = 2v
Car b: v + 15 = d / 1.5
We can solve for v by substituting the first equation (rearranged to isolate d) into the second:
v + 15 = 2v / 1.5
1.5v + 22.5 = 2v
0.5v = 22.5
v = 45
We're looking for the speed of car b, which was v + 15 = 45 + 15 = 60.
Answer:
32 degrees
Step-by-step explanation:
All angles in a triangle add up to 180.
118 + 30 = 148
To find what's missing, subtract that from 180.
180 - 148 = 32 degrees
Hope this helped. :)
