Answer:
2 hours 1 minute 9.23 seconds
Step-by-step explanation:
Since they are traveling in opposite directions, their separation speed is the sum of the magnitudes of their speeds: 30 +22 = 52 mph.
The time is related to speed and distance by ...
time = distance / speed
= (105 mi)/(52 mi/h = 2 1/52 h ≈ 2 h 1 min 9.23 sec
It will take a little over 2 hours before they are 105 miles apart.
Answer:
The slope of RT is: m = 1
Step-by-step explanation:
Given
Determining the slope between (-3, 1) and (2, 6)
![\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=%5Cmathrm%7BSlope%7D%3D%5Cfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
![\left(x_1,\:y_1\right)=\left(-3,\:1\right),\:\left(x_2,\:y_2\right)=\left(2,\:6\right)](https://tex.z-dn.net/?f=%5Cleft%28x_1%2C%5C%3Ay_1%5Cright%29%3D%5Cleft%28-3%2C%5C%3A1%5Cright%29%2C%5C%3A%5Cleft%28x_2%2C%5C%3Ay_2%5Cright%29%3D%5Cleft%282%2C%5C%3A6%5Cright%29)
![m=\frac{6-1}{2-\left(-3\right)}](https://tex.z-dn.net/?f=m%3D%5Cfrac%7B6-1%7D%7B2-%5Cleft%28-3%5Cright%29%7D)
Refine
![m=1](https://tex.z-dn.net/?f=m%3D1)
Therefore, the slope of RT is: m = 1
If you add those two numbers together you get 67. 67-23=44 :)
-20 would be 20 (positive)
4 would be -4 (negative
95 would be -95 (negative)
-63 would be 63 (positive)
3 67/100
3 will stay a whole number so you put that as the whole number. 67 is 67 percent of a whole. so you put it over 100.
