Answer:
X
Step-by-step explanation:
X+y=X so the answers x
The value of x using the two rectangles is 8.
We have,
A rectangle is a 2-D shape with length and width.
The length and width are different.
If the length and width are not different then it is a square.
The area of a rectangle is given as:
Area = Length x width
Rectangle A:
Area
= length x width
= 6 x 4
=24 cm²
Rectangle B:
Area
= length x width
= 3x cm²
Now,
The area of both triangles is the same.
This means,
Area of first rectangle = Area of the second rectangle
24 = 3x
x = 24/3
x = 8
Thus,
The value of x using the two rectangles is 8.

What does the number 0.7 represent?
The ball bounces to 30% of its previous height with each bounce.
The height at which the ball bounces at the nth bounce is 0.3 feet.
The ball bounces to 70% of its previous height with each bounce.
The height from which the ball was dropped at the nth bounce is 0.7 feet.
Answer:
The ball bounces to 70% of its previous height with each bounce.
Step-by-step explanation:
In physics terminology, the number 0.7 is the coefficient of restitution. It is the ratio of the height of bounce (n+1) to the height of bounce (n).
The meaning of the number is that the ball bounces to 70% of the height of the previous bounce.
Answer:
The ball bounces to 70% of its previous height with each bounce.
Step-by-step explanation:
A ball is dropped from a certain height. The function below represents the height f(n), in feet, to which the ball bounces at the nth bounce:
f(n) = 9(0.7)n
The number 0.7 represents that the ball bounces to 70% of its previous height with each bounce.
A)5.217
B)5.783
C)21.743
D)6.815
