The size of
of height 
First, we calculate the width using the following equivalent ratios

Express as fraction

Solve for x


Hence:
--- approximated
So, we have:


The size (diagonal) is then calculated using:




--- approximated
the answer of it is $2 the original price
Answer:
x = -19.75
Step-by-step explanation:









Answer: $0.05
Step-by-step explanation:
Mean of a given set of numbers simply means that one should find the average of the numbers. Therefore, the mean change of the stock prices will be:
= ($1.25 + -$0.75 + $1.25 + -$0.75 + -$0.75) / 5
= $0.25 / 5
= $0.05
Therefore, the mean change of the stock prices is $0.05.
Answer:
b=3 b=0
Step-by-step explanation:
-8|4b-6|+9=-39
Subtract 9 from each side
-8|4b-6|+9-9=-39-9
-8 | 4b-6| = -48
Divide by -8
-8/-8 | 4b-6| = -48/-8
| 4b-6| = 6
When solving the absolute value, there is a positive and a negative solutions
4b-6 = 6 and 4b-6 = -6
Add 6 to each side
4b-6+6 =6+6 4b-6+6 = -6+6
4b =12 4b = 0
Divide by 4
4b/4 =12/4 4b/4 = 0/4
b=3 b=0
