The total change is the sum of the length of two boards she cut.
First board length is 1 7/8th feet. Let's change to improper fraction:
1 7/8 = 15/8 feet
Second board lengrh is 3.5 feet, or 3 1/2 feet. Let's change to improper fraction:

Let's add the two:
The change in original board is 43/8 feet

Which number is greater,
23×10^3
or
11×10^4?
How do you know? Explain your steps.
[tex]11\times 10^4[/tex] is the greater number among the given.
The given numbers are 23×10³ and [tex]11\times 10^4[/tex].
We need to identify which is the greater number among the given.
What is scientific notation?The scientific notation helps us to represent the numbers that are very huge or very tiny in a form of multiplication of single-digit numbers and 10 raised to the power of the respective exponent. The exponent is positive if the number is very large and it is negative if the number is very small.
Now, 23×10³=23×1000=23000 and [tex]11\times 10^4[/tex]=11×10000=110000
Therefore, [tex]11\times 10^4[/tex] is the greater number among the given.

Step-by-step explanation:
One of the rows in the table has an error and does not have the same ratio as the other rows.
Conversion Chart
Feet
Inches
Row 1

36
Row 2

72
Row 3

94
Row 4

Which explains how to correct the error in the table?
Row 1 should show 3 feet is equivalent to 32 inches.
Row 2 should show 6 feet is equivalent to 66 inches.
Row 3 should show 7 feet is equivalent to 84 inches.
Row 4 should show 9 feet is equivalent to 104 inches.
Answer:
Row 3 should show 7 feet is equivalent to 84 inches.
Step-by-step explanation:
First divide 36 and 3 to find the constant proportion. Which you get 12
Now multiply 12 x 3 , 12 x 6, 12 x 7, and 12 x 9
You should be able to find the incorrect answer which is row 3
12 x 7 actually equals 84 not 94
Hope this makes sense!

6(x - 8) = 96
Answer:
x= 24
Step-by-step explanation:
Multiply each term in the parentheses. Not sure if this helps but I hope it does.
6(x−8)=96
(6)(x)+(6)(−8)=96(Distribute)
6x+−48=96
