Answer:
504 km
Step-by-step explanation:
divide 180 by 15 (because 3 hours is 180 minutes)
after you divide you get 12
then multiply 12 by the 42 kilometers and you get 504
Answer:
You could use one quarter and two dimes... that will equal $0.45
(I'm not sure what you are asking for)
Answer:
This is simple. The answer is 60 for the first, and the second one I believe is 85
Step-by-step explanation:
Since we are dealing with quadrilaterals, we know that all the inside angles add up to 360. In your isosceles trap. the top two angles are the same, and the bottom two are the same. So, we can do 120*2=240 for the top angles, and then subtract that from 360. 360-240=120. 120/2=60

The average rate of change over the interval
is 2.17
Explanation:
Given that the cost of a floral bouquet after a discount is given by the function ![f(x)=2.17x-10.00](https://tex.z-dn.net/?f=f%28x%29%3D2.17x-10.00)
We need to determine the average rate of change over the interval ![(12,24)](https://tex.z-dn.net/?f=%2812%2C24%29)
The average rate of change can be determined using the formula,
![\frac{f(b)-f(a)}{b-a}](https://tex.z-dn.net/?f=%5Cfrac%7Bf%28b%29-f%28a%29%7D%7Bb-a%7D)
where
and ![b=24](https://tex.z-dn.net/?f=b%3D24)
Substituting the value of a and b in the function, we get,
![f(12)=2.17(12)-10.00](https://tex.z-dn.net/?f=f%2812%29%3D2.17%2812%29-10.00)
![=26.04-10.00](https://tex.z-dn.net/?f=%3D26.04-10.00)
![=16.04](https://tex.z-dn.net/?f=%3D16.04)
![f(24)=2.17(24)-10.00](https://tex.z-dn.net/?f=f%2824%29%3D2.17%2824%29-10.00)
![=52.08-10.00](https://tex.z-dn.net/?f=%3D52.08-10.00)
![=42.08](https://tex.z-dn.net/?f=%3D42.08)
Hence, substituting these values in the formula, we get,
![\frac{f(b)-f(a)}{b-a}=\frac{42.08-16.04}{24-12}](https://tex.z-dn.net/?f=%5Cfrac%7Bf%28b%29-f%28a%29%7D%7Bb-a%7D%3D%5Cfrac%7B42.08-16.04%7D%7B24-12%7D)
Simplifying, we get,
![\frac{f(b)-f(a)}{b-a}=\frac{26.04}{12}](https://tex.z-dn.net/?f=%5Cfrac%7Bf%28b%29-f%28a%29%7D%7Bb-a%7D%3D%5Cfrac%7B26.04%7D%7B12%7D)
Dividing, we have,
![\frac{f(b)-f(a)}{b-a}=2.17](https://tex.z-dn.net/?f=%5Cfrac%7Bf%28b%29-f%28a%29%7D%7Bb-a%7D%3D2.17)
Thus, the average rate of change over the interval
is 2.17
