Answer:

To solve this problem, we can use the laws of indices, specifically the law that states that (a^m)^n = a^(m*n).

So, we have:

(1/64)^(2/3) = (1^(2/3))/(64^(2/3))

Since any number raised to the power of 1 is itself, we can simplify the numerator to just 1.

Now, we have:

(1/64)^(2/3) = 1/(64^(2/3))

To evaluate 64^(2/3), we can use the law of indices again, which states that a^(1/n) = nth root of a. In this case, we have:

64^(2/3) = (64^(1/3))^2 = 4^2 = 16

So, substituting this back into the original expression, we have:

(1/64)^(2/3) = 1/16

Therefore, (1/64)^(2/3) simplifies to 1/16.

Step-by-step explanation:

Answer:

Using the law of indices, we have:

(1/64)^(2/3) = (1^(2/3))/(64^(2/3))

Now we need to simplify the denominator by finding the cube root of 64:

64^(1/3) = 4

Substituting this value in the original expression, we get:

(1/64)^(2/3) = (1^(2/3))/(4^2)

Simplifying further, we have:

(1/64)^(2/3) = 1/16

Step-by-step explanation:

The composite figure has a total area of 102 square units (80 + 16 + 6 square units). Consequently, the composite figure has a 102 square unit area.

Composite things that are three dimensional (3D) are constructed from two or more separate pieces. Finding each item's outside surface area and adding the surface areas together will yield the surface area of a 3D composite object. Another way to divide it is into a top and a bottom.

We may divide the composite figure into smaller forms and sum up their areas to determine the area of the overall figure. Here is one method for breaking down the figure:

A rectangle and two triangles make up the figure.

The rectangle has an area of 80 square units since it is 10 units long and 8 units wide.

The two triangles have right triangles with four and six unit-long legs, respectively. The equation (base * height) / 2 may be used to calculate each triangle's area.

The area of the triangle on the left is (4 * 8) / 2 or 16 square units since its base is 4 units and its height is 8 units (the length of the rectangle).

The area of the triangle on the right is (6 * 2) / 2 or 6 square units because its base is 6 units and its height is 2 units (the distance between the bottom of the triangle and the bottom of the rectangle).

Answer: x = -1 and y = 9

Step-by-step explanation:

To solve this system of equations, we can use the substitution method.

First, solve the first equation for y:

y = -x + 8

Now, substitute this expression for y into the second equation and solve for x:

4x + y = 5

4x + (-x + 8) = 5 (substituting -x + 8 for y)

3x + 8 = 5

3x = -3

x = -1

Now that we have found the value of x, we can substitute it back into one of the original equations to solve for y. Let's use the first equation:

y = -x + 8

y = -(-1) + 8

y = 9

Therefore, the solution to the system of equations is x = -1 and y = 9.

The capacity of the mug is 1.2. The capacity of the mug can be found by using the equation C = (3/4) ÷ (5/8).

It is the maximum amount of output that can be produced in a given period of time. Capacity is usually expressed in terms of units per unit of time, such as gallons per minute or passengers per hour.

In this equation, 3/4 represents the amount of water in the mug, and 5/8 represents the amount the mug is full.

Let the capacity of the mug be x.

Given,

Mug is 5/8 full and contains 3/4 of water

So, 5/8 of the mug is filled with water

Therefore,

5/8 of x = 3/4

(5/8 )x = (3/4)

x = (3/4) × (8/5)

x = (24/20)

x = 1.2

Therefore, the capacity of the mug is 1.2.

For fau/cet filter:

For pitcher-filter:

Let's start with the fau/cet model:

Contribution margin per unit = selling price - variable cost

Contribution margin per unit = $90 - $25

Contribution margin per unit = $65

Contribution margin ratio = contribution margin per unit / selling price

Contribution margin ratio = $65 / $90

Contribution margin ratio = 0.722

The sales mix is 2 faucet models for every 3 pitcher filters sold, so the contribution margin weighted average is:

= (2/5)($65) + (3/5)($90-$20)

= $42

Now we can calculate the break-even point in units for the faucet model:

= Total fixed costs / contribution margin per unit

= $1,200,000 / $42

= 28,571 units

For pitcher filter:

Contribution margin per unit = selling price - variable cost

Contribution margin per unit = $110 - $20

Contribution margin per unit = $90

Contribution margin ratio = contribution margin per unit / selling price

= $90 / $110

Contribution margin ratio = 0.818

Contribution margin weighted average:

= (2/5)($25) + (3/5)($90-$20)

= $54

Break-even point in units for pitc/her filter:

= Total fixed costs / contribution margin per unit

= $1,200,000 / $54

= 22,222 units

Break-even point in dollars for fau/cet model:

= 28,571 units x $90 per unit

= $2,571,390

Break-even point in dollars for pitc/her-filter:

The marginal cost function is $ 4000.72.

What is the marginal cost function?

The overall costs involved in producing an additional good are what is referred to as the marginal cost. Hence, it can be evaluated by changes in the costs associated with each extra unit. Marginal Cost is calculated as Total Expenditure Change / Unit Production Change.

Here, we have

Given: C(x) = 20+4000x+0.09x²

We have to find the marginal cost function.

We differentiate the given function and we get

C(x) = 20+4000x+0.09x²

C'(x) = 4000 + 2×0.09x

To determine how fast the cost is increasing when x=4.

C'(4) = 4000 + 2×0.09(4)

C'(4)  = 4000.72

Hence, the marginal cost function is $ 4000.72.

The percentage of reduction in consumption required to keep the same expenditure is 25%.

Inflation is an economic phenomenon that occurs when the prices of goods and services increase over time.

To find out the percentage of reduction in consumption, we need to calculate the difference between the current and the original prices of the butter.

This can be done by subtracting the original price of the butter from the current price of the butter (25% costlier).

The difference can be expressed as a percentage by dividing the difference by the original price.

Therefore, the percentage of reduction in consumption required to keep the same expenditure is 25%.

This means that a housewife needs to reduce her consumption of butter by 25% in order to keep her expenditure the same.

a)  The number of units that produces maximum profit is q = 12.

b) The price per unit that produces maximum profit is p = $39.

c)  The maximum profit is P = $386.

What is profit?

a) To find the number of units that produces maximum profit, we need to find the point where revenue equals cost. The revenue function is given by:

R(q) = pq = (63-2q)q = 63q - 2q²

The cost function is given by:

C(q) = 70 + 15q

The profit function is given by:

P(q) = R(q) - C(q) = (63q - 2q²) - (70 + 15q) = -2q² + 48q - 70

To find the number of units that produces maximum profit, we take the derivative of the profit function with respect to q, and set it equal to zero:

P'(q) = -4q + 48 = 0

Solving for q, we get:

q = 12

Therefore, the number of units that produces maximum profit is q = 12.

b) To find the price per unit that produces maximum profit, we substitute q = 12 into the price function:

p = 63 - 2q = 63 - 2(12) = 39

Therefore, the price per unit that produces maximum profit is p = $39.

c) To find the maximum profit, we substitute q = 12 and p = 39 into the profit function:

P = -2q² + 48q - 70 = -2(12)² + 48(12) - 70 = $386

Therefore, the maximum profit is P = $386.

Answer:

You can use the formula for the volume of a cuboid, which is Volume = length x width x height

You are given the volume of the cuboid as 108cm^3, the length as 4cm, and the width as 9cm. Let's substitute these values into the formula and solve for the height:

108cm^3 = 4cm x 9cm x height

To solve for height, you can divide both sides by 36 (which is equal to 4cm x 9cm) to isolate height:

108cm^3 ÷ 36 = 4cm x 9cm x height ÷ 36

3cm = height

So the height of the cuboid is 3cm.
