9x-5x+10+1+4-6
4x+9
Answer:
3 hours
Step-by-step explanation:
The rate of bus is 50
The rate of car is 55
Which means, per hour, the Car catches up by 55 - 50 = 5 miles
Since, the car starts AFTER the bus has already travelled 15 miles, the CAR IS BEHIND by 15 miles. To catch up these 15 miles (at the rate of catching up 5 miles per hour), the car would need:
15/5 = 3 hours to catch up with the BUS
<u>Note:</u> we use the formula
d = rt
where d = distance
r is rate
t is time
Thus, we had:
d = rt
t = d/r
t = 15/5
t = 3
Thus, after 3 hours, the car with catch up with the bus
The only cards you can be dealt are: 8, 9, 10, J, Q, K.
That means there is a 1 in 6 chance... or a 17% chance.
Answer:
AB or x =6sqrt(3) (which is what the pic ask for)
but you ask for AC which is 9
Step-by-step explanation:
The hypotenuse is twice the length of the short leg.
The short leg is 3sqrt(3) (because I see it is opposite the smallest angle which is 30 in this case).
So the hypotenuse is twice 3sqrt(3) which is 6sqrt(3)
You are also asking for AC though... That is the short leg times sqrt(3) so that measurement is 3sqrt(3)*sqrt(3)=3(sqrt(3*3))=3(3)=9
ab
= ----------
3(a-b)
this is your answer
