Keri and his friends are on their way to visit some family friends who lives 1050 miles away from them. based on the route they shoes they expect to complete their trip in three days. the distance and average speeds for the first two days driven are shown below:
first day : 5 hours at an average speed of 70 miles per hour
second day: 7 hours at an average an average speed of 65 miles per hour
if the average speed on the third day is 70 miles per hour how many more hours will it take for them to reach their friends home

3.5 hours

Step-by-step explanation:

5 x 70 = 350

7 x 65 = 455

350 + 455 = 805

1050 - 805 = 245

245/ 70 = 3.5

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.

step-by-step explanation:

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
