Given the expression 1/4 - 3/5, select the addition problem that is equivalent to it.
Given that,
An expression [tex]\dfrac{1}{4}-\dfrac{3}{5}[/tex]
To find,
The value of above expression.
Solution,
We have,
[tex]\dfrac{1}{4}-\dfrac{3}{5}[/tex]
The LCM of 4 and 5 is 20.
[tex]\dfrac{1}{4}-\dfrac{3}{5}=\dfrac{(5)-4(3)}{20}\\\\=\dfrac{5-12}{20}\\\\=\dfrac{-7}{20}[/tex]
So, the required answer is [tex]\dfrac{-7}{20}[/tex].

A 3-column table with 3 rows. Column 1 is labeled Seller with entries wholesaler, Distributor, Retail Store. Column 2 is labeled markup with entries 0 percent, 100 percent, 80 percent. Column 3 is labeled Selling Price with entries 80 cents, A, B. A distributor buys packs of trading cards from a wholesaler for $0.80 each. The distributor marks up the cards by 100% before selling them to stores. How much does the distributor sell each pack of cards for? The stores then mark up the cards another 80% before selling them to customers. How much does the retailer sell a pack of cards for? A = B =
Answer:
Step-by-step explanation:
Answer:
$1.60
$2.88
Step-by-step explanation:
To find the selling price of the distributor and the retailer, we first need to find how much the distributor sells each pack of cards.
To find the selling price we use the formula.
Selling Price = Cost + Markup
Cost = $0.80
Markup rate = 100% or 1
Selling Price = 0.80 + (0.80*1)
Selling Price = $1.60
So the distributor sells each pack of cards at $1.60 to the retailer.
Now to find the selling of the retailer, we need to use the selling price of the distributor.
Cost = $1.60
Markup rate = 80% or 0.80
Selling price = 1.60 + (1.60 * 0.80)
Selling price = $2.88
So the retailer sells each pack of cards at $2.88 to the customers.
Answer:
A = $1.60
B = $2.88

Chloe invests money in an account paying simple interest. She invests $200 and no money is added or removed from the investment. After one year, she has $204. What is the simple percent interest per year?
Answer:
2%
Step-by-step explanation:
Chloe's simple interest for 1 year is $4. You can get this by subtracting the amount she invested from the total amount she got after one year.
$204 - $200 = $4Now that we know the simple interest, we can now get the simple interest rate or simple percent interest per year by dividing $4 by $200.
$4 ÷ $200 = 0.02Let's change 0.02 into a percentage.
0.02 x 100 = 2%This means that every year, her investment will earn a 2% simple interest.
Answer:
2%
Step-by-step explanation:
A 1125 ft^3 open-top rectangular tank with a square base x ft on a side and y ft deep is to be built with its top lush with the ground to catch runoff water. The costs associated with the tank involve not only the material from which the tank is made but also an excavation charge proportional to the product xy.a. If the total cost isc = 5(x^2 + 4xy) + 10xy,what values of x and y will minimize it?b. Give a possible scenario for the cost function in part (a).
Answer:
The values of x and y that will minimize the cost is 15 ft and 5 ft respectively and the minimum cost will 3,375
Step-by-step explanation:
With a 1125 ft^3 open-top rectangular tank with a square base x ft on a side and y ft deep is to be built with its top lush with the ground to catch runoff water, x is the length, y is the height;
x^2*y = 1125
y = 1125/x^2 ----(1)
The total cost of c = 5(x^2 + 4xy) + 10xy
Then,
c = 5(x^2 + 4x*(1125/x^2)} + 10x*(1125/x^2)
c = 5x^2 + 22,500/x + 11,250/x
c = 5x^2 + 33,750/x
To minimize the cost of c, find the derivatives of c; c'
c' = 10x - 33,750/x^2
c' = (10x^3 - 33,750)/x^2
c'(x) = 0; 10x^3 = 33,750
x = ³√33,750 = 15
x = 15; y = 1125/x^2
y = 1125/15^2 = 5
(x,y) = (15,5)
c = 5x^2 + 33,750/x
c = 5*15^2 + 33,750/15 = 3,375
The values of x and y that will minimize it is 15 ft and 5 ft respectively and the minimum cost will 3,375
The values of x and y that will minimize the cost is 15ft and 5ft. The minimum cost is 3,375
We have volume of a rectangular tank = 1125 ft^3
Side of a rectangular tank = x ft and
Length of a rectangular tank =y ft
So, [tex]x^2y = 1125[/tex]
[tex]y = \frac{1125}{x^2} ...(1)[/tex]
The total cost of rectangular tank (c) = [tex]5(x^2 + 4xy) + 10xy[/tex]
[tex]c = 5(x^2 + 4x(\frac{1125}{x^2} ) )+ 10x(\frac{1125}{x^2} )\\c = 5x^2 +\frac{22,500}{x} + \frac{11250}{x} \\c = 5x^2 + \frac{33750}{x}[/tex]
Differentiating it w.r.t x, we get
[tex]c' = 10x - 33,750/x^2\\c' =\frac{10x^{3}-33750 }{x^{2} } \\c'(x) = 0\\10x^3 = 33,750\\x = \sqrt[3]{33,750} \\ = 15\\x = 15; y = \frac{1125}{x^2} \\y = \frac{1125}{15^{2} } \\= 5\\(x,y) = (15,5)\\c = 5x^2 + \frac{33750}{x} \\c = 5(15)^2 + 33,750/15 \\= 3,375[/tex]
The values of x and y that will minimize the cost is 15 ft and 5 ft and the the minimum cost is 3,375.

A 100-square grid has 70 shaded squares. Explain how you could express this model as a fraction, percent, and decimal
Answer:
the answer would be 70/100 in fraction form, 70% in percent, and (i believe) 0.7 min decimal form. Hope this helps!
Answer:
70 out of 100 is the ratio 70 Over 100 apostrophe , so it represents 70%. 70 Over 100 can be reduced by dividing the numerator and the denominator by 10 to get the reduced fraction 7 Over 10. Dividing 7 by 10 results in the decimal equivalent 0.70.
