Answer:

the correct option is D : 1

Step-by-step explanation:

The equation is r(x) = 10x - 0.025x² where x is measured in thousands of toys produced, and r(x) is measured in thousands of dollars.

For maximum r, r'(x) = 0

It becomes: r'(x) = [tex]10-0.025\times2x=0[/tex]

= [tex]10-0.5x=0[/tex]

[tex]x=\frac{10}{0.05}[/tex]

x= 200

Hence, r(200) = [tex]10\times200-0.025\times200^{2}[/tex]

Solving it we get,

r(200) = 1000

Hence, maximum revenue the company can earn with this toy is $1000.

Answer:

a)35 cubic meters=35000 liters.

b)450 cubic centimeters= 450 milliliters.

c)19.74 cubic meters=19740 cubic decimeters.

d)926 cubic centimeters=0.926 cubic decimeters.

Step-by-step explanation:

a) since one cubic meter = 1000 liters,

              35 cubic meters=35 X 1000=35000 liters

b) Since one cubic centimeters=1 milliliter,

               450 cubic centimeters=450 milliliters.

c)Since one meter = 10 decimeters, one cubic meter=10³ decimeters.

Hence 19.74 cubic meters= [tex]19.74X10^{3} =19740[/tex] cubic decimeters.

d) Since once centimeter=0.1 decimeter, 1 cubic centimeter=0.1³ decimeters.

Hence 926 cubic centimeters=[tex]926X0.1^{3}=0.926[/tex] cubic decimeters.

a. 35 cubic meters to liters:

1 cubic meter = 1000 liters

so 35 cubic meters = 35 x 1000 = 35,000 liters

b. 450 cubic centimeters to milliliters:

1 cubic centimeter = 1 milliliter

Therefore 450 cubic centimeters = 450 milliliters

c. 19.74 cubic meters to cubic decimeters:

1 cubic meter = 1000 cubic decimeters

so 19.74 cubic meter = 19.74 x 1000 = 19740 cubic decimeters

d. 926 cubic centimeters to cubic decimeters:

1 cubic centimeters = 0.001 cubic decimeters

so 926 cubic centimeters = 926 x 0.001 = 0.926

1.25x40=50

Answer: Hi!

Andre earns $165 for each digital projector that she sells.

We know that she works 11 hours per day, 5 days per week and that she sells 12 digital projectors a week. We want to know the average hourly wage.

First, we need to know how much she wins in the week. This is the number of digital projectors sold multiplied by the profit for each one:

12*$165 = $1980

And now we need to see how the amount of hours that she works each week, this is 11 hours per day and 5 days per week, then she works 11*5 = 55 hours per week.

Now we can divide the earns per week by the number of hours that she works each week, and obtain the average hourly wage:

$1980/55 = $36

So Andre wins an average of $36 per hour.

160 = 2 x 2 x 2 x 2 x 2 x 5 = 2^5 x 5

243 = 3 x 3 x 3 x 3 x 3 = 3^5

So

(160 * 243)^1/5

= 5th root of (160 * 243)

= 5th root of (2^5 * 5 * 3^5)

= 2 * 3 * (5th root of 5)

= 6 * (5th root of  5)

Answer is D. 6 * (5th root of  5)

The resultant expression, equivalent to [tex](160*243)^{1/5}[/tex] is Option (D) [tex]6\sqrt[5]{5}[/tex]

An exponent refers to the number of times a number is multiplied by itself. It is represented as a number or letter written above and to the right of a mathematical expression called the base. It indicates that the base is to be raised to a certain power. x is the base and n is the exponent or power.

Represented as [tex]x^{n}[/tex]

Given expression is [tex](160*243)^{1/5}[/tex].

Now we are separating the expression,

160 = 2*2*2*2*2*5 = [tex]2^{5}*5[/tex]

243 = 3*3*3*3*3 = [tex]3^{5}[/tex]

∴ [tex](160*243)^{1/5}[/tex] =  [tex](2^{5}*5*3^{5})^{1/5}[/tex] = [tex]2*3*5^{1/5}[/tex] = [tex]6\sqrt[5]{5}[/tex]

Final answer:

A student who drinks 64 ounces of coffee each day consumes 182.5 gallons per year, after converting ounces to gallons (64 ounces/day × 365 days/year, then divided by 128 ounces/gallon).

Explanation:

To calculate the amount of coffee a student drinks per year in gallons, we first need to understand the relationship between ounces and gallons. We know that 1 gallon is equivalent to 128 fluid ounces. So, to find out how many gallons 64 ounces represent, we divide 64 by 128.

64 ounces per day × 365 days per year = 23,360 ounces per year.

Next, divide the total annual ounces by the number of ounces in a gallon:

23,360 ounces per year ÷ 128 ounces per gallon = 182.5 gallons per year.

Therefore, rounded to the nearest tenth, a student drinks 182.5 gallons of coffee each year.

A member and a nonmember must each take 10 music lessons in order for the cost to be the same for both.

To find the number of music lessons that must be taken by a member and a nonmember so that the cost for each is the same, we can set up an equation. Let x represent the number of music lessons. For a member, the cost is $100 + $20x, and for a nonmember, the cost is $30x. We can set up the equation:

100 + 20x = 30x

To solve for x, we can subtract 20x from both sides:

100 = 10x

Then, we can divide both sides by 10:

x = 10

Therefore, a member and a nonmember must each take 10 music lessons in order for the cost to be the same for both.

For this question you are required to determine what is called a slope and y-intercept. To thoroughly explain, a slope is a constant factor while a y intercept is simply a number on the y-axis, for instance (0,1)

In order to determine slope, you would take two ordered pairs  and use the following y2 - y1 divided by x2 - x1 to determine slope.

On the first attachment, take two ordered pairs.

-1 - (-3) divided by 1-0

2/1 = 2

m = 2

On the second attachment, use a principle called rise over run to determine the slope.

Using the method above, we “rise” two boxes and “run” one box, therefore the slope for the second attachment would be 2 and if we go down 2 we determine that the y-intercept is 0

Applying the explanation, we determine for the first attachment that the most sufficient answer is y = 2x - 3

The answer for the second attachment is y = 2x

If you start with 1 cheerleader in row A, then you'll have 3 cheerleaders in row B (add on 2), and then 5 cheerleaders for row C (add on another 2), etc etc.

Note how: 1+3+5 = 4+5 = 9 which is a perfect square. Also note that 36 is a perfect square.

Rule: The sum of the first positive n odd numbers is going to be equal to n^2. In the example of adding the first three odd numbers (1,3,5), we have n^2 = 3^2 = 9 as the sum

So as you can see, we'll have n = 6 rows because n^2 = 6^2 = 36 and

1+3+5+7+9+11 = 36

which is the sum of the first six positive odd numbers. So we'll have 1 cheerleader in row A, 3 in row B, 5 in row C, 7 in row D, 9 in row E, 11 in row F to have 6 rows total.

To determine the number of rows in the triangular formation, set up an equation and solve for x. The number of rows is 6.

To determine the number of rows in the triangular formation, we can set up a series of equations.

Let x be the number of rows.

The first row will have 1 cheerleader, the second row will have 3 cheerleaders, the third row will have 5 cheerleaders, and so on.

We can set up the equation: 1 + 3 + 5 + ... + (2x-1) = 36.

This is the sum of an arithmetic sequence with a common difference of 2. Solving for x, we get x = 6.

Therefore, there will be 6 rows in the formation.
