REPOST !!!! Write a proportion using an unknown value x and the ratio 5 : 6. Then solve it.
2 answers:
Answer:
x = 10
Step-by-step explanation:
Given the ratio, 5:6, which is also the same as ⅚. In order to solve for the unknown value, x, we can establish the following proportion:
Perform cross-multiplication:
6x = 60
Divide both sides by 6:
x = 10
In order to verify its validity, substitute the value of x into the original proportion:
Perform cross-multiplication:
10 × 6 = 5 × 12
60 = 60 (True statement).
Therefore, the value of x = 10.

Answer:
9 represents the initial height from which the ball was dropped
Step-by-step explanation:
Bouncing of a ball can be expressed by a Geometric Progression. The function for the given scenario is:
The general formula for the geometric progression modelling this scenario is:
Here,
represents the initial height i.e. the height from which the object was dropped.
r represents the percentage the object covers with respect to the previous bounce.
Comparing the given scenario with general equation, we can write:
= 9
r = 0.7 = 70%
i.e. the ball was dropped from the height of 9 feet initially and it bounces back to 70% of its previous height every time.
