Answer:

to compare she must calculate...

1) ((2*3)+2)/3 she get 2.666

2) ((2*7)+5)/7 she get 2.714

by approximation the two are the same and she had enough flour.

Using approximation, the two are the same and she has enough flour.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

Given that Karina buys a small bag of flour that contains [tex]2\frac{2}{3}[/tex] cups of flour. The recipe calls for [tex]2\frac{5}{7}[/tex] cups of flour.

1)   [tex]2\frac{2}{3}[/tex] cups of flour.

=  ((2 x 3)+2)/3

= 2.666

Hence, she get 2.666

2)  [tex]2\frac{5}{7}[/tex]  cups of flour.

= ((2x 7)+5)/7

= 2.714

Hence, she get 2.714

Using approximation, the two are the same and she has enough flour.

Answer:

[tex]2~2/9[/tex] gallons per minute

Step-by-step explanation:

If it drains at a rate of [tex]x[/tex] gallons in [tex]y[/tex] minutes, the tub drains [tex]x/y[/tex] gallons in [tex]1[/tex] minute.

We can plug in for [tex]x[/tex] and [tex]y[/tex] for this equation!

The amount it drains in one minute is [tex]5/(2~1/4)=5/(9/4)=20/9=2~2/9[/tex].

So, the answer is [tex]\boxed{2~2/9}[/tex] gallons per minute.

The quantity of water that drains out of the tub each minute is 2.23 gallons.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that water drains out of the bathtub at a rate of 5 gallons in 2¹/₄ minutes.

2¹/₄ minuts = 5 gallons

1 minute = 5 / 2¹/₄

1 minute = 5 /2.25

1 minute = 2.23 gallons

Therefore, the quantity of water that drains out of the tub each minute is 2.23 gallons.

Answer:

The first answer is because it takes time while your doing it

The original price of the nail polish with a 150% markup sold at $8.75 is $3.50.

Let x be the original price of the polish.

Walmart marked up 150%.

Selling Price = Original Cost + Mark-up

therefore the selling price = x + 150% of x

we know the selling price is $8.75

Therefore, substituting the values:

8.75 = x + 150% of x

convert percentages to decimals:

8.75 = x + 1.5x

combine like terms:

8.75 = 2.5x

divide by 2.5 into both sides:

3.5 = x

use reflexive property:

x = $3.50

Thus, the original price of the nail polish is $3.50.
