Answer:
That's right!
Step-by-step explanation:
All of the points are in the right places! :P
So, you basically plug the values into the formula you have been given. D divided by T gives you the average speed.
We know the distance D is 145 miles and the Time T is 2.5 hours.
So, 145/2.5=58
Therefore, the cars average speed was 58 miles / hour
Answer:
B
Step-by-step explanation:
40+88+15=128+15=143
There are three rectangles that compose this shape. The first one has side lengths of 5 & 8 (l times w=a 5 times 8=40, area of the rectangle is 40). The second one has side lengths of 8&11 (8 times 11=88, area is 88). Final rectangles has side lengths of 16-(8+5) and 5 (16-13=3, 3 times 5=15, Area=15). All three of those rectangles added up is 143 as an area of the figure.
Answer:
(A)
Step-by-step explanation:
Point A is at (-2,4)
Rule of a 180° rotation about the origin: (x,y) --> (-x,-y)
Using the rule, (-2,4) will become (2,-4).
A' should be (2,-4) or Option A.
