Answer:

644,262 copies

Step-by-step explanation:

Since this is a proportion problem, and we are given three values and one variable which is the total number of copies sold to date (x). Then we can use the Rule of Three to solve this problem. To do this we simply multiply the diagonal values and divide by the last value which would give us the value of the variable x

39,300 copies  <======>  6.1%

    x   copies   <=======>  100%

(100*39,300) / 6.1 = 644,262 copies

Therefore, a total of 644,262 copies have been sold to date.

this should be correct, im sorry im wrong.

Step-by-step explanation:

Answer:

Look at explanation

Step-by-step explanation:

y = mx + b

m is the slope, and b is the y-intercept

So basically on the y-axis, which is the vertical line, u will make a point on 4, and that point is where your line will go through. And then 3 is the slope ur line will be going in, meaning that the line will go up 3 square units, or number, while only going one square unit to the right. It's going up and right because it's a positive number. So it should look like this:

Answer:

Naomi charges $8 an hour to mow lawns

Step-by-step explanation:

first day // 2 1/2= 2.5 hrs

2nd day // 4 1/4= 4.25 hrs

2.5hrs + 4.25hrs = 54hrs // 6.75hrs = 54hrs

/6.75    /6.75

= 8hrs

Answer:

He has 0 yards

Step-by-step explanation:

Initially he lost 10 yards

This means that he is 10 yards away from the starting point which we shall call origin

Afterwards, he gained 10 yards

what this mean is that he is back at the original point before the loss

Since he gained what he lost, then he is back at the origin and then we can say that no yards was lost or gain so we have him gaining 0 yards only

Answer:

Your answer, many solutions is correct!

Step-by-step explanation:

The answer one solution is incorrect because there is more than one solution to this equation.

The answer no solution is incorrect because there is a solution to this equation so clearly, this one is incorrect.

The answer many solutions is correct because there are two solutions to this equation, [tex]y=-3,\:x=\frac{9}{2}[/tex].

Answer:

yeah correct

Step-by-step explanation:

The correct format of the question is

The value of a rare baseball card issued in 1989 is represented by the function f(x) = [tex]0.2x^3- 0.25x^2+3x +4[/tex] where x represents the number of years since the baseball card was issued. Use the Remainder Theorem to find the value of the card in 1999

Answer:

The value of the card in 1999 is 209

Step-by-step explanation:

The remainder theorem says that

If you divide a Polynomial by f(x) be a Linear factor of the form (x-a) the remainder will be equal to F(a).

f(x) = [tex]0.2x^3- 0.25x^2+3x +4[/tex]  

So we need to find from 1989 to 1999 which is 10 years

so our a = 10

Factor will be x-10

Applying remainder theorem

[tex]\frac{ 0.2x^3 -0.25x^2+3x+4}{x-10}[/tex]

we will get

Quotient = [tex]0.2x^2 + 1.75x +20.5[/tex]

Remainder = 209

Verifying our result

F(10) = [tex]0.2(10)^3 -0.25(10)^2 + 3(10) + 4[/tex]

        = 200 -25 + 30 + 4

        = 209

Division Property of Equality

Step-by-step explanation:

Answer:

y = -6

Step-by-step explanation:

-4-2y=-12

4+8y=-24

We can eliminate 4.

4+8y-4-2y = -12-24

Simplify.

6y = -36

Find y.

y = -36 ÷ 6

Simplify.

y = -6

Answer:

-4-2y=-12

4+8y=-24

by elimination method,

-4 - 2y = -12

4 + 8y = -24

---------------

0 + 6y = -36

6y = -36

y = -36/6

y = -6

Answer:

The answer is A. 1385 cm2

Step-by-step explanation:

Use the formula A = pi times radius squared

Answer:

A. 1385 cm²

Step-by-step explanation:

Area of a circle is πr²

We know what the radius is, so all we have to do is plug it in.

π(21)²

π(21)²= 1385.44

Since it's approximate, it would just be 1385 cm²

Move the decimal So that you have one number to the left of it. Count the number of spaces it was moved. Remove all trailing 0’s.

Multiply by 10 raised to the power of the number is spaces the decimal was moved.

Answer:

$5.625

Step-by-step explanation:

Cost per pound of beef = $1.25 per pound

Number of pounds purchased = 3.5 pounds

Amount given to cashier = $10.00

Amount of change to receive from cashier =?

Amount issued to cashier - total cost of beef

Total cost of beef = (number of pounds * cost per pound)

Total cost of beef = (3.5 * 1.25) = $4.375

$10 - $4.375 = $5.625

Answer:

-5

Step-by-step explanation:

y=mx+b is the slope intercept formula.

m is the slope.

Answer:

slope = - 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 5x - 1 ← is in slope- intercept form

with slope m = - 5

Answer:

No, it is not a right triangle.

Step-by-step explanation:

The simplest way to determine is testing out the numbers with Pythagorian theorem.

If it complies with the theorem, it is a right triangle.

let's assume c = 28, b = 21, and a = 20

the longest side is the hypotenuse so side c (28 in) will be the hypotenuse.

According to the Pythagorian theorem, the square of the length of hypotenuse must equal to the sum of squares of other two sides.

check:

c^2 = 28^2 = 784

a^2 + b^2 = 21^2 + 20^2 = 841

because c^2 is not equal to a^2 + b^2, the triangle is not a right triangle.
