Answer:
![AB = 6](https://tex.z-dn.net/?f=AB%20%3D%206)
Step-by-step explanation:
Given
![BC = 3.8](https://tex.z-dn.net/?f=BC%20%3D%203.8)
![A'B' = 15](https://tex.z-dn.net/?f=A%27B%27%20%3D%2015)
![B'C' = 9.5](https://tex.z-dn.net/?f=B%27C%27%20%3D%209.5)
Required
Determine the length of AB
Because A'B'C'D is a dilation of ABCD, then the following relationship must exist:
![A'B' : AB = B'C' : BC](https://tex.z-dn.net/?f=A%27B%27%20%3A%20AB%20%3D%20B%27C%27%20%3A%20BC)
Substitute values for A'B', B'C' and BC
![15 : AB = 9.5 : 3.8](https://tex.z-dn.net/?f=15%20%3A%20AB%20%3D%209.5%20%3A%203.8)
Express the ratio as fractions:
![\frac{AB}{15} = \frac{3.8}{9.5}](https://tex.z-dn.net/?f=%5Cfrac%7BAB%7D%7B15%7D%20%3D%20%5Cfrac%7B3.8%7D%7B9.5%7D)
Multiply through by 14
![15 * \frac{AB}{15} = \frac{3.8}{9.5} * 15](https://tex.z-dn.net/?f=15%20%2A%20%5Cfrac%7BAB%7D%7B15%7D%20%3D%20%5Cfrac%7B3.8%7D%7B9.5%7D%20%2A%2015)
![AB = \frac{3.8}{9.5} * 15](https://tex.z-dn.net/?f=AB%20%3D%20%5Cfrac%7B3.8%7D%7B9.5%7D%20%2A%2015)
![AB = \frac{3.8* 15}{9.5}](https://tex.z-dn.net/?f=AB%20%3D%20%5Cfrac%7B3.8%2A%2015%7D%7B9.5%7D)
![AB = \frac{57}{9.5}](https://tex.z-dn.net/?f=AB%20%3D%20%5Cfrac%7B57%7D%7B9.5%7D)
![AB = 6](https://tex.z-dn.net/?f=AB%20%3D%206)
Answer:
133.33 mph
Step-by-step explanation:
The small trick is to notice the time. Is it 8:00 AM the same day. We don't know, but we will assume it is.
So the truck was on the road for 2 hours.
The car was on the road for 2 - 1/2 = 1 1/2 = 1.5 hours.
The distance travelled was 200 miles
Solution
d = r * t
200 = r * 1.5
200/1.5 = r
r = 133.33 miles / hour
The noise you hear is a siren trying to catch up to the car.
Answer:
85
Step-by-step explanation:
because A is half of that and if you divided 170 by 2 you would get 85, I think that's how you do it.
