SportCo manufactured 6400 basketballs

SportCo manufacturers fixed expenses for producing basketballs = $46,270

Variable expense incurred per basketball produced = $6.50

Total expenses incurred by SportCo for producing basketballs= $87,870

Fixed costs are costs that remain constant regardless of whether more or fewer goods or services are produced or sold.

An expense for the company that varies according to how much is produced or sold is called a variable cost. Depending on a company's production or sales volume, variable costs grow or fall. They climb as production rises and reduce as production declines.

Let x be the number of basketballs produced by the manufacturer SportCo.

Formulating the equation we get:

Fixed cost + Variable cost*Number of basketballs produced = Total expenses incurred by the manufacturer

46270 + 6.5(x) = 87870

6.5(x) = 41600

x = 6400

Therefore, the number of basketballs produced is 6400 by the manufacturer.

Inverse of the given function F(x) = 3 x³- 4 is F⁻¹(x) = ∛[ ( y + 4 ) / 3 ]

Given is a function of x, F(x) = 3 x³- 4

These question can be solved by following 4 easy steps

Step 1 : Switch the F(x) with the variable y

This implies, F(x) = 3 x³- 4 becomes y =  3 x³- 4

Step 2 : Interchange the variable x and y in the above obtained equation

This implies, from the equation y = 3 x³- 4, we get

x =  3 y³- 4

Step 3 : Solve the new obtained equation for y

This implies, we have to simplify the equation by rearranging the terms to get the equation in terms of the variable x.

x =  3 y³- 4

=> x + 4 = 3 y³

=> 3 y³ = x + 4

=> y³ = ( x + 4 ) / 3

=> y = ∛( x + 4 ) / 3

Hence we obtain the required equation.

Step 4 : Switch the variable y with F⁻¹(x)

This implies, y = ∛( x + 4 ) / 3 becomes F⁻¹(x) = ∛( x + 4 ) / 3

Therefore, we get the inverse of the given function F(x) = 3 x³- 4 as F⁻¹(x) = ∛( x + 4 ) / 3

Step-by-step explanation:

Answer:

what is the correct solution

Step-by-step explanation:

Answer:

6:22, 9:33

Step-by-step explanation:

When writing equivalent ratios, you use two of the numbers from the original ratio and multiply them evenly to get an equivalent ratio.

[tex]\mathrm{p:q~or~\frac{p}{q} = \frac{x(p)}{x(q)}}\\\mathrm{\frac{6 \times 2}{11 \times 2} = 6:22}\\\mathrm{\frac{6 \times 3}{11 \times 3} = 9:33}[/tex]

Answer:

6:22 and 9:33

Step-by-step explanation:

Answer: 6:22 and 9:33

Think of the ratio like a fraction, one way to find an equivalent ratio is to simplify the current ratio. But in this case, we are unable because we can divide 3 by 3 to get one, but not 11 by 3.

3 divided by 3 = 1

11 divided by 3 = does not evenly divide

Another way is to multiply both numbers by the same number.

3 times 2 = 6

11 times 2 = 22

And we can just keep doing the same with different numbers.

3 times 3 = 9

11 times 3 = 33

The large square covers more

(See attachment below)

Explanation- The large square has the highest dimension and by extension, it has the highest area.

This means that, less large squares will be needed to cover more areas compared to other sizes of the squares

Area of the square =(side)².

square, in geometry, a plane figure with four equal sides and four right (90°) angles. A square is a special kind of rectangle and a special kind of parallelogram.

By observation,

9 small squares are equivalent to one large square, implying that the 5 large squares are giving us 45 small squares.

4 small squares can fit into one medium square, implying that the 10 medium squares are giving us 40 small squares.

There are only 10 small squares.

Hence, the large square covers more of the plane

Rick paddles in still water at a rate of 6.5 mph. The rate of the current is 1.5 mph.

The rate at which an object moves from one point to another is also called speed. It can be measured by dividing the distance over time.

rate = distance/time

Let x = rate at which Rick paddles

c = rate of the current

If Rick paddles a kayak 20 miles upstream in 4 hours, and going upstream means the current is against your direction, then the equation for the travel is:

x - c = 20 miles/4 hours

x - c = 5     (equation 1)

If the return trip downstream takes him 2.5 hours, and downstream means that the current is going the same direction as you are, then the equation for the downstream travel is:

x + c = 20 miles/2.5 hours

x + c = 8     (equation 2)

Using elimination method, solve the two equations.

x + c = 8

x - c = 5

2x     = 13

x = 6.5

rate at which Rick paddles = 6.5 mph

Substitute x in equation 1 and solve for c.

x - c = 5     (equation 1)

6.5 - c = 5

c = 6.5 - 5

To solve the inequality:

Given: 2(4)x⁺³≤8

Then,

[tex]\begin{aligned}&2 \cdot 4 x^3 \leq 8\\&8 x^3 \leq 8\\&8 x^3+(-8) \leq 8+(-8)\\&8 x^3-8 \leq 8-8\\&8 x^3-8 \leq 0\\&2^3 \cdot x^3-2^3 \leq 0\\&2^3\left(\frac{2^3 \cdot x^3}{2^3}-\frac{2^3}{2^3}\right) \leq 0\\&8\left(x^3-1\right) \leq 0\\&x^3-1 \leq 0\\&x^3-1^3 \leq 0\end{aligned}[/tex]

Then,

So,

[tex]\begin{aligned}&\left\{\begin{array}{l}x=1 \\x_1=\frac{-1+\sqrt{3} \cdot i}{2} \\x_2=\frac{-1-\sqrt{3} \cdot i}{2}\end{array}\right.\\&\left\{\begin{array}{l}x=1 \\x_1=-\frac{1}{2}+\frac{\sqrt{3}}{2} i \\x_2=-\frac{1+\sqrt{3} \cdot i}{2}\end{array}\right.\\&\left\{\begin{array}{l}x=1 \\x_1=-\frac{1}{2}+\frac{\sqrt{3}}{2} i \\x_2=-\frac{1}{2}-\frac{\sqrt{3}}{2} i\end{array}\right.\\&\left\{\begin{array}{l}x \leq 1 \\x \geq 1\end{array}\right.\end{aligned}[/tex]

So, finally, it gives:

[tex]2 \cdot 4 x^3 \leq 8\\2 \cdot 4 \cdot 0^3 \leq 8\\\begin{aligned}&x \leq 1 \\&x \in(-\infty, 1]\end{aligned}[/tex]

The probability that a girl is chosen is 1/10 and the probability that a left-handed girl is chosen is 11/20.

Probability may be defined as the possibility of occurrence of an event. Probability of an event can be 0 or 1 but it can never be negative. If probability is 0 then the event will not occur and if probability is 1 then the event will definitely occur. Probability is given by the formula.

Probability = Favorable outcomes/Total number of outcomes.

Here, total number of outcomes = 20.

Now in the first case we need to find probability of picking a girl so favorable outcome is 2.

Probability of picking a girl = 2/20

Probability of picking a girl = 1/10

In the second case we need to find probability of picking a left-handed girl, so the favorable outcomes are 2 + 9 = 11 as total number of girls are 2 and total number of left-handed people are 9.

Probability of picking left-handed girl = 9 + 2/20

Probability of picking left-handed girl = 11/20

Thus, probability that a girl is chosen is 1/10 and the probability that a left-handed girl is chosen is 11/20.
