209 to the nearest hundredth is 200.
209 to the nearest tenth is 210.
Answer:
55 ft.
Step-by-step explanation:
First find the area of Lot X
67 • 70 = 4,690
Subtract the are of Lot X from the total area
8,375 - 4,690 = 3,685
3,685 is the area of Lot Y
Now divide 3,685 by the length of Lot Y : 67
3,685 ÷ 67 = 55
The width of Lot Y is 55 ft.
Hope this helps!
Answer:
![D(t)=-24t+166](https://tex.z-dn.net/?f=D%28t%29%3D-24t%2B166)
Step-by-step explanation:
Let
D(t) = the distance to the safe zone (measured in meters)
t = time (measured in seconds)
<u>Given:</u>
Rachel's rate = 24 meters per second
At
seconds
meters
<u>Find:</u> D(t)
Rachel's rate is the slope of the function D(t). Since the distance is decreasing when the time is increasing, the slope must be negative.
Hence, the function expression is
![D(t)=-24t+b](https://tex.z-dn.net/?f=D%28t%29%3D-24t%2Bb)
To find b, substitute
and ![D(t_1)=70:](https://tex.z-dn.net/?f=D%28t_1%29%3D70%3A)
![70=-24\cdot 4+b\\ \\70=-96+b\\ \\b=70+96\\ \\b=166](https://tex.z-dn.net/?f=70%3D-24%5Ccdot%204%2Bb%5C%5C%20%5C%5C70%3D-96%2Bb%5C%5C%20%5C%5Cb%3D70%2B96%5C%5C%20%5C%5Cb%3D166)
So,
![D(t)=-24t+166](https://tex.z-dn.net/?f=D%28t%29%3D-24t%2B166)
