A six sided number cube :

Sample space = 1,2,3,4,5,6

Non composite numbers on a six sided number cube = 1,2,3,5

Probability of an event = required outcome / Total possible outcomes

Required outcome = number of non composite number = 4

Total possible outcomes = sample space = 6

P(not composite)= 4/6 = 2/3

In 2012, a company made $410,000 in sales in Seattle but only making $255,000 in sales in Portland. Fulfill each of the following claims:

a. Seattle outsold Portland in sales by 60.78%.

b. Portland's sales lagged Seattle's by 60.78%.

c. Sales in Portland were 62.2% of those in Seattle.

a. Seattle's sales were ___% larger than Portland's.

To calculate the percentage difference between the two sales figures, we can use the following formula:

Percentage difference = ((larger value - smaller value) / smaller value) x 100%

Substituting the values, we get:

Percentage difference = ((410,000 - 255,000) / 255,000) x 100%

Percentage difference = 155,000 / 255,000 x 100%

Percentage difference = 0.6078 x 100%

Percentage difference = 60.78%

Therefore, Seattle's sales were 60.78% larger than Portland's.

b. The sales in Portland were ___% less than those in Seattle.

Since Portland's sales were smaller than Seattle's, we can simply use the percentage difference we calculated above to find the percentage by which Portland's sales were smaller:

Portland sales were 60.78% smaller than Seattle's.

c. Portland sales were ___ % of Seattle's.

To calculate the percentage of Seattle's sales that Portland's sales represent, we can use the following formula:

Percentage = (smaller value / larger value) x 100%

Percentage = 0.62195 x 100%

Substituting the values, we get:

Percentage = (255,000 / 410,000) x 100%

Percentage = 62.2%

Therefore, Portland's sales were 62.2% of Seattle's.

Part A: The actual dimensions of the pool are 10 feet long and 5 feet wide.

Part B: the cost of the cover for the pool would be $15.00.

Dimension is a measure of a physical property of an object, such as its length, breadth, height, or mass.

Part A: The actual dimensions of the pool can be determined by using the given scale. To do this, we need to convert the given measurements in inches to feet. We can do this by dividing the given measurements in inches by the scale, which is 2 inches equals 7 feet.

The actual length of the pool is 20 ÷ 2 = 10 feet.

The actual width of the pool is 10 ÷ 2 = 5 feet.

Therefore, the actual dimensions of the pool are 10 feet long and 5 feet wide.

Part B: To calculate how much it would cost to buy a cover for the pool, we need to determine the area of the pool. We can do this by multiplying the length by the width of the pool.

Area = length x width

Area = 10 ft x 5 ft

Answer:

To solve 2^x = 32, we need to find the value of x that satisfies the equation.

We can rewrite 32 as a power of 2 by noting that 2^5 = 32. Therefore, we have:

2^x = 2^5

Since the bases of the powers are equal, we can equate the exponents:

x = 5

So the solution to 2^x = 32 is x = 5.

To rewrite this equation in a logarithmic form, we can use the definition of logarithms:

log(base 2)32 = x

Here, the logarithm with base 2 of 32 is equal to x.

The volume of the solid is approximately 0.558 cubic units.

To find the volume of the solid, we need to integrate the area of the semi-circles along the a-axis.

We know that the diameter of each semi-circle is the distance between the functions f(x) and g(x), which is:

d(a) = f(a) - g(a) = ln(a) + 1 - (a-1) = ln(a) - a + 2

The radius of each semi-circle is half of the diameter, which is:

r(a) = (ln(a) - a + 2) / 2

The area of each semi-circle is π times the square of its radius, which is:

[tex]A(a) = πr(a)^2 = π/4 (ln(a) - a + 2)^2[/tex]

To find the volume of the solid, we integrate the area of each semi-circle along the a-axis, from a = e to a = 2:

V = ∫[e,2] A(a) da

V = ∫[e,2] π/4 [tex](ln(a) - a + 2)^2 da[/tex]

V ≈ 0.558 (rounded to the nearest thousandth)

Therefore, the volume of the solid is approximately 0.558 cubic units.

If Yellow Sticker Business meets its operating income goal, the quarterly safety margin in dollars will be $4,583.33.

Budgeting, debt reduction, and setting up an emergency fund are important short-term objectives. Key insurance policies should be included in medium-term goals, whilst retirement should be the primary emphasis of long-term objectives.

Next, we deduct our break-even sales from actual sales at the goal operating income level to determine the margin of safety:

Real sales are determined by dividing target operating income by total fixed costs and contribution margin ratio.

Real sales equal $8,250 plus $15,000 / 0.60.

Real sales were $29,583.33

Safety margin = Real sales Breakeven sales

Answer:

y = -4x + 5

Step-by-step explanation:

y = mx + b

From the graph, we see the line intersects the y-axis at 5, so the y-intercept, b, is 5.

y = mx + 5

slope = m = rise/run

rise = up and down

run = left and right

We go up 4 units from the lower point to the upper point. That is a rise of 4 units. Then we go left 1 unit. That is a run of -1.

slope = m = 4/(-1) = -4

y = mx + 5

y = -4x + 5

The volume of the capsule is [tex]3052.08 mm^3[/tex]

What is volume of the hemisphere ?

The formula for the volume of a hemisphere is [tex]V = (2/3)\pi r^3[/tex], where r is the radius of the hemisphere.

The volume of a hemisphere is half of the volume of a full sphere with the same radius. This is because a sphere can be divided into two hemispheres of equal size. Therefore, we can use this formula to find the volume of a hemisphere:

[tex]V = (1/2) (4/3)\pi r^3[/tex]

Simplifying this expression, we get:

[tex]V = (2/3)\pi r^3[/tex]

So, the volume of a hemisphere is [tex](2/3)\pi r^3[/tex].

According to the question:
To find the volume of a capsule, we need to break it down into two parts: a cylinder and two hemispherical ends.

The formula for the volume of a cylinder is[tex]Vcylinder = \pi r^2h[/tex], where r is the radius of the cylinder and h is its height.

The formula for the volume of a sphere (or hemisphere) is[tex]Vsphere = (4/3)\pi r^3.[/tex]

Since the capsule is made up of two hemispheres and a cylinder, the total volume of the capsule is the sum of the volumes of these three parts:

[tex]Vcapsule = 2Vsphere + Vcylinder[/tex]

First, let's calculate the volume of the cylinder. We are given that the radius is 3mm and the height is 100mm, so we have:

[tex]Vcylinder = \pi r^2h = 3.14 x 3^2 x 100 = 2826 mm^3[/tex]

Next, let's calculate the volume of the hemispheres. Since the capsule has a radius of 3mm, each hemisphere has a radius of 3mm. So, we have:

[tex]Vsphere = (4/3)\pi r^3 = (4/3) ( 3.14) (3^3 )= 113.04 mm^3[/tex]

Finally, we can calculate the total volume of the capsule by adding the volume of the cylinder and the two hemispheres:

[tex]Vcapsule = 2Vsphere + Vcylinder = 2 *113.04 + 2826 = 3052.08 mm^3[/tex]

Therefore, the volume of the capsule is [tex]3052.08 mm^3[/tex].

The volume of the pyramid is V = (1/3) (3²) (5) = 45 cm³ thus the rate at which the water level is rising when the water level is 3 cm is 45 cm³/sec.

Volume is a measure of the amount of space that an object occupies or contains. It is measured in terms of cubic units, such as cubic metres or cubic centimetres. Volume is a three dimensional measure, which means it takes into account the length, width and height of an object.

The rate at which the water level is rising when the water level is 3 cm can be calculated using the formula for the volume of a pyramid. The formula for the volume of a pyramid is V = (1/3) bh², where b is the area of the base and h is the height. In this case, the base is a square with sides of length 3 cm and the height is 5 cm. Therefore, the volume of the pyramid is V = (1/3) (3²) (5) = 45 cm³.

Since the water is being filled at a constant rate of 45 cm³/sec, then the rate at which the water level is rising when the water level is 3 cm is 45 cm³/sec. This is because the water level is rising at the same rate at which the water is being filled, and since the water is being filled at a rate of 45 cm³/sec, the water level is also rising at the same rate. This is why the rate at which the water level is rising when the water level is 3 cm is 45 cm³/sec.

Answer:

20.8

Step-by-step explanation:

Let h be the height of the ladder. We know that the distance BC is 8 ft, and the angle of elevation BAC is 69 degrees. Therefore, we have:

tan(69) = h/8

Multiplying both sides by 8, we get:

8*tan(69) = h

Using a calculator, we get:

h ≈ 20.8 ft

Therefore, the height of the top of the ladder from the ground is approximately 20.8 feet.

An equation to represent relationship of the weights shown on the scale include the following: 22 + x = 34.

Based on the information provided about the weights on this balanced scale, we can logically deduce the following parameters;

Each small square = 1 unit.

Each larger square = 10 units.

The variable x represent the weight of the triangle.

Since there are four small squares and three large squares each labeled ten on one side of this balanced scale, we have:

Total weight = 4(1) + 3(10)

Total weight = 34 units.

Similarly, there are two small squares, two large squares, and a triangle labeled x on the other side of this balanced scale, we have:

Total weight = 2(1) + 2(10) + x

Total weight = 22 + x

By equating the two equations, we have:

22 + x = 34

x = 34 - 22

x = 12
