Darryl has written 60 percent, or 12 pages, of his history report. Darryl wants to figure out how many pages he needs to write. Darryl’s work is shown below.
Step 1: Write 60 percent as a ratio. StartFraction part Over whole EndFraction = StartFraction 60 Over 100 EndFraction
Step 2: Write an equivalent ratio using the number of pages done so far. StartFraction 60 Over 100 EndFraction = StartFraction 12 Over question mark EndFraction
Step 3: Rewrite as: 12 (100) divided by 60.
Step 4: 120 divided by 60 = 2
What mistake did Darryl make?
In Step 1, Darryl should have written the ratio as StartFraction 100 Over 60 EndFraction.
In Step 2, Darryl should have put 12 in the denominator.
In Step 3, Darryl should have multiplied 60 and 100.

Answer: d = ³⁄₂
Steps: -½d + ⅝ = ⅜d - ¹¹⁄₁₆
Subtract ⅝ from both sides: -½d + ⅝ - ⅝ = ⅜d - ¹¹⁄₁₆ - ⅝
Simplify: -½d = -²¹⁄₁₆ + ⅜d
Subtract ⅜d from both sides: -½d - ⅜d = -²¹⁄₁₆ + ⅜d - ⅜d
Simplify: -⅞d = -²¹⁄₁₆
Multiply both sides by 8: 8(-⅞d) = 8(-²¹⁄₁₆)
Simplify: -7d = -²¹⁄₂
Divide both sides by -7: -7d ÷ -7 = -²¹⁄₂ ÷ -7
Simplify: d = ³⁄₂

Question: What is the constant of proportionality for the above table.
Answers
Answer:
Step-by-step explanation:
you have to add them.
The constant of proportionality for the given table representing amount of money earned in number of days is equal to $25.
The constant of proportionality in a table of proportionality represents the relationship between the values in the two columns.
It is a fixed value that you can multiply or divide by any number in the first column to obtain the corresponding value in the second column.
Let's understand this with the given table:
Table attached.
To find the constant of proportionality,
Take any row and divide the number in the second column by the number in the first column.
Let's use the second row (14 and 350):
Constant of proportionality = 350 ÷ 14 = 25
As for every row in the table, if multiply the number in the first column by 25, you will get the number in the second column.
For example:
25 × 7 = 175
25 × 14 = 350
25 × 21 = 525
Here, the constant of proportionality is $25.
Therefore, the constant of proportionality is indeed 25, as multiplying each number in the first column by 25 to get the corresponding values in the second column for any row in the table.

What is meant by the method of unitary?The unitary method is a process that involves determining the value of a single unit and then calculating the value of the necessary number of units based on that value. The unitary method could be of two types: direct variation as well as inverse variation. The unitary method's formula is to identify the value of a specific unit and then multiply that amount by the number of units to arrive at the required value.For the given question;
Paul earns $288 for working 32 hours.
This can be written as;
32 hours -----> $288.
For working 1 hour the salary will be.
1 hours -----> $288/32.
For working 25 hours, multiply both sides by 25.
25 hours -----> $288×25/32
25 hours -----> $225
Thus, for working 25 hours Paul will earn $225.
