The percent of the purchase price would be 20% of the sale price.

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.

First we need to calculate the difference between the purchase and sale price.

$72.00 - $60.00 = $12.00

Since $12 is the increase in dollars.

To increase as a percentage we need to divide the increase by the original purchase price.

12.00 ÷ 60.00 = 0.2

This simply means moving the decimal place two columns to the right;

0.2 x 100 = 20

Therefore, the percent of the purchase price would be 20% of the sale price.

Step-by-step explanation:

Answer: y=10.50x

Step-by-step explanation:

The y in this equation represents the dependent varible which is our output what we are solving for. We know that Rafeal gets $10.50 per hour but we don't know how many hours he works so to represent the time we use the variable x. If we were to solve this we would take the hours that he worked and multiplied the number of hours by $10.50 to get y the cost which he earns.

The equation that represents the given statement will be equal to y = 10.50(x) and y is the dependent variable.

Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.

This relationship is illustrated by the left and right expressions being equal to one another. The left-hand side equals the right-hand side is a basic, straightforward equation.

As per the data mentioned in the question,

Earning made by Rafael per hour = $10.50

Let the number of hours working is x.

Then, the equation that represents the given statement,

y = 10.50(x)

Here, y is the total money earned by Rafael.

Answer:

the answer is 2.59x10^7

Given container can hold 2143.57 cu. cm. water.

[tex]V=\frac{4}{3}\times \pi \times r^{3}[/tex],

where 'r' is the radius of the sphere.

For given example,

We have been given a spherical container having radius = 8 cm

The amount of water container can hold = the volume of this spherical container

Using the formula of the volume of the sphere,

[tex]V=\frac{4}{3}\times \pi \times r^{3} \\\\V=\frac{4}{3}\times 3.14 \times 8^{3} \\\\V=2143.57~cm^3[/tex]

Therefore, this container can hold 2143.57 cu. cm. water.

Answer:

8i is an imaginary number.

4(x/8 - 2) = 1/4(2x - 1/2) is the complete equations for having infinitely many solutions.

We know two simultaneous equations have a unique solution when they intersect at a point,

when they are parallel they have no solution and when they are coinciding they have an infinite no. of solutions.

Given, 4( x/8 - 2) = 1/4(2x -___.

(1/2)x - 8 = (1/8)x - ___.

Now, RHS is half of RHS so the blank space should be (-8/4) = -2.

And we know if one equation is some constant multiple of another they are also coinciding and have an infinite no. of solutions.

Step-by-step explanation:

multiply all of the choices

10x15x6x4

The total number of possible salads you could create is 3600. so the correct option is B.

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.

WE have been given the following choices: 10 dressings, 15 vegetables, 6 cheese toppings and 4 different crouton toppings.

Therefore, the total number of possible salads you could create;

Then multiply all of the choices

10 x 15 x 6 x 4

= 3600

Hence, The total number of possible salads you could create is 3600. so the correct option is B.

Answer: -2 1/2

Step-by-step explanation:

First term = a = -40

Common ratio = 2nd term / First term = 20 / -40 = -1/2

Answer:

The subject 'x' in terms of 'y'

[tex]x = \sqrt{\frac{y+2}{3} }[/tex]

Step-by-step explanation:

Explanation:-

Given subject in terms of 'x'

 y = 3 x² - 2

Adding '2' on both sides, we get

y + 2 = 3 x² - 2 +2

y+2 =  3 x²

Dividing '3' on both sides, we get

[tex]x^{2} = \frac{y+2}{3}[/tex]

[tex]x = \sqrt{\frac{y+2}{3} }[/tex]
