How can you use the fraction in the first column to
write the equivalent decimal in the second column?
Answers
Answer: Create a lookup from the unusable fraction format to one that you can use in excel:
First column in the lookup should be the fraction in unusable format
Second column should be the fractions in a usable format, first format the cells in second column > Format Cells menu > Number tab > Category as Fraction > Type "Up to one digit (1/4)"
Manually in the corresponding cells the equivalent values (for example, below in cell H2 write 5/8)

Answer:
Step-by-step explanation:
Firstly you should times the first decimal of the column by the number that is the numerator. So the second column the numerator is 2 so you times the first number by 2 which gives you 0.10. You do this for every column then you get you answer.

Nick had $100 in a saving account over the next 6 months he worked at a seasonal store where each month he earn $400 and spent $250 he put the remaining amount in his savings account each month now that the job is over he plans to spend 200 per month for how many months can he make withdrawal from his savings account until his balance is zero dollars
Answers
If he plans to spend 200 per month, then the number of months he can make withdrawals from his savings account until his balance is zero dollars is equal to 5.
First, we calculate the money earned by Nick in 6 months
Money earned per month = $400
Money earned in 6 months = 400 × 6 = 2400
If he spends $250 out of the money earned per month, then the money spent in these 6 months can be calculated as follows;
Money spent per month = 250
Money spent in 6 months = 250 × 6 = 1500
Now we calculate the money put in the saving account in 6 months by subtraction;
Money added to the saving account = 2400 - 1500 = $900
As he already had $100 in the saving account,
Total amount of money in the saving account = 900 + 100 = 1000
If he plans to spend 200 per month, then the number of months he can make withdrawals can be calculated by division
Number of months = total money in the account ÷ money spent per month
Number of months = 1000 ÷ 200 = 5
Therefore, Nick can make withdrawals for 5 months from his savings account.

b. If you buy 7 markers, how much would each marker cost?
Answers
If you buy 7 markers , each marker would cost 9.42 ( cents ) .
Given : The total cost ( in cents ) of x + 2 markers is x³ + 5 x ² + 2 x - 8 .
To find : cost of 1 marker
Cost of 1 marker = ( x³ + 5 x ² + 2 x - 8 ) / ( x + 2 )
= [tex]x^{2}[/tex] + 3 x - 4
Substituting value of 7 in cost function
= [tex]x^{2}[/tex] + 3 x - 4 at x = 7
= 49 + 21 - 4
Cost of 7 markers = 66
Cost of 1 marker = 66 / 7
= 9.42

If the total price for two cars at a dealership is $ 108 , 000 $108,000, where one car’s price is $ 9000 $9000 less than twice the other, what is the price of the cheaper vehicle?
Answers
The price of the cheaper vehicle is $39,000
Calculating CostFrom the question, we are to determine the price of the cheaper vehicle
Let the cost of one of the cars b $x
and the cost of the other car be $y
From the given information,
The total price for two cars at a dealership is $108,000
That is
x + y = 108000 ----------- (1)
and
one car’s price is $9000 less than twice the other
x = 2y - 9000 ----------- (2)
Put equation (2) into equation (1)
x + y = 108000
2y - 9000 + y = 108000
2y + y - 9000 = 108000
2y + y = 108000 + 9000
3y = 117000
y = 117000/3
y = 39000
∴ The price of one of the vehicles is $39,000
Substitute this value into equation (2)
x = 2y - 9000
x = 2(39000) - 9000
x = 78000 - 9000
x = 69000
The price of the other vehicle is $69,000
Hence, the price of the cheaper vehicle is $39,000

The perimeter of rectangular classroom with its length five times its width is 108 ft.
What is perimeter of rectangle?The perimeter of rectangle is the sum of length of all its sides. Mathematically, it can be written as -
Perimeter = 2 (Length + Breadth)
Given is the width of rectangular classroom which is 9 ft wide. Its length is five times its width. From this, we can write -
Width [W] = 9 ft
Length [L] = 5W = 5 x 9 = 45 ft

Answers
The percentage of decay for the exponential function: y = 18(0.75) x is 25%.
How to illustrate the information?This equation represents exponential decay. Whenever the base is less than 1, the function represents decay. When the base is greater than 1, the function represents growth. In this case, the base is 0.75 which is less than 1, representing decay.
The formula for exponential decay is y=a(1-r)x.

The height of the candle which is a linear function with respect to time after 12 hours was 25.2 centimeters.
What is a linear function?A linear function has a graph of a straight line.
Given that height of a candle is a linear function of the amount of time in hours it has been burning.
The slope(m) is = - 0.4 which is = -(4/10) = - (2/5).
The height of the candle after 19 hours is 22.4 centimeters, which can be written as two points (x,y) = (19,22.4).
Now to obtain the height of the candle first we have to form an equation of a line in slope intercept form to find y-intercept(b), which is,
y = mx + b.
22.4 = -(2/5).19 + b.
22.4 = -7.6 + b.
b = 22.4 + 7.6.
b = 30.
∴ y = -(2/5)x + 30.
Now to obtain the height of the candle after 12 hours we have to substitute 12 in x.
So, y = -(2/5)(12) + 30.
y = 25.2 centimeters.

As we know sin2x = 2 sin x. cos x
3( 2 sin x. cos x)² + 2 sin x. cos x - 2 = 0

3 ( 2t)² - 2t - 2 = 0
12t² - 2t - 2 = 0
12t² - 6t + 4t - 2 = 0
