Answer:
48 km/h
Step-by-step explanation:
The average speed is calculated by distance divided by time. So 228 / 4.45 gets the answer.
This is a multi step problem. For this we do system of equations.
2.5x + 7y = 82.50
X+y = 24
To do the elimination method we have to make the y values equals to each other so we multiply the x+y=24 equation by 7
7x +7y = 168
-
2.5x + 7y = 82.50
———————————-
4.5x = 85.50

4.5. 4.5
X = 19

Answer:
C). Nonrigid transformation.
F). Stretch
Step-by-step explanation:
Transformation in mathematics is defined as the alteration or variation in the shape of an object without altering the lengths by using a flip, turn, slide, or resizing.
The transformation 'Hexagon ABCDEF → hexagon A'B'C'D'E'F'' would best be described as the 'non-rigid' and 'stretch' transformation. Non-rigid because it alters the shape or size of the figure both vertically as well as horizontally. It would be considered a stretch transformation as it is resized by a pull from both the vertical and horizontal angles. Thus, <u>options C and F</u> are the correct answers.
If the center of dilation is A, this means that point A is invariant.
- This means you can eliminate C and D.
Also, the scale factor is 3/4, which means that A'C' is more than half the length of AC.
- This is best reflected by option B
