Answer:

170 in²

Step-by-step explanation:

This trapezoid is broken up into two shapes: a triangle and a parallelogram.

The formula for area of a triangle is b (base) × h(height) ÷ 2.

The base of the triangle is 4 and the height is 10.

b (base) × h(height) ÷ 2

10 × 14 ÷ 2 = 70

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

The formula for area of a parallelogram is b (base) × h(height).

The base of the parallelogram is 10 and the is 10 as well.

b (base) × h(height)

10 × 10 = 100.

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

Lastly, add both areas.

100 + 70 = 170

Therefore, the area of this figure is 170 in².

Answer:

91.3 degrees celsius

Step-by-step explanation:

Here, we want to calculate the mean temperature of the 30 cups

From what we have here, if we multiplied the mean by the count of cups, we have the total

That means, we have the total temperature of all as;

(10 * 89.6) + (20 * 92.1) = 2,738

So to get the temperature of the thirty, we divide this by 30 as follows;

2,738/30 = 91.3

Answer:

B) 5 + 17i is your answer.

Step-by-step explanation:

In order to write this equation as a complex number in standard form, you must first simplify each term.

Apple the distributive property.

21 - 4i - 1 * 16 - (7i) + 28i

Multiply -1 by 16.

21 - 4i -16 - (7i) + 28i

Multiply 7 by -1.

21 - 4i - 16 - 7i + 28i

Now simplify by adding terms :)

Subtract 16 from 21.

5 - 4i - 7i + 28i

Subtract 7i from -4i.

5 - 11i + 28i

Add -11i and 28i.

= 5 + 17i

A reflection about a line gives an image that is at an equal distance from the line but on the opposite (other) side of the line

The distance between the lines m and n is 6 units

Reason:

The given parameters are;

\(T_{<0, -12>}\Delta(XYZ) = (R_n \circ R_m) \Delta (XYZ)\)

Let Y represent the top vertex of Δ(XYZ), and the coordinates of point Y is (3, 0) we have;

The coordinates of Y following \(T_{<0, -12>}\) is Y''(3, -12)

A reflection of  Y across the line m, y = -9, gives the coordinates of the image at Y'(3, -18)

A reflection of the image Y'(3, -18) across the line n, y = -15, gives the image at Y''(3, -12)

The distance between lines m, and line n, is -9 - (-15) = 6

Generally, the difference between two lines of reflection, n, and m, following a composite reflection is 2×(n - m)

Given that the total transformation is -12, we have;

2×(n - m) = -12

Therefore;

\((n - m) = \dfrac{-12}{2} = -6\)

Which gives;

m - n = 6

The distance between the two lines = 6 units

Even though dividing a fraction by a whole number might be challenging, it is simple to achieve with a few steps. By placing the full number above 1, you must first divide it into a fraction. After that, multiply the fraction you are dividing by the inverted version of the fraction. Lastly, simplify the response as much as possible.

For instance, to multiply 3/4 by 2:

Put 2 over 1, making it 2/1, to make it a fraction.

To get 1/2, invert 2/1.

To get 3/8, multiply 3/4 by 1/2.

Divide the numerator and denominator by 3 to get 1/4, which is the simplest representation of the fraction 3/8.

Hence, 1/4 is equivalent to 3/4 when divided by 2.

Step-by-step explanation:

Estimated standard error in the bottom of the independent-measures t statistic is a measure of the variability of the sample means.

When the same experiment were repeated many times then estimated standard error help us to find the amount of variability.

Specifically, it measures the standard deviation of the sampling distribution of the mean differences between two independent groups.

When we conduct a t-test to compare the means of two independent groups.

Use the estimated standard error to determine the amount of variability.

Expect to see in the means of those groups if we repeated the experiment many times.

The larger the estimated standard error, the more variability  would expect to see in the means.

And the less confidence can have in our conclusion about whether the means of the two groups are significantly different from each other.

On the other hand, a smaller estimated standard error indicates that there is less variability in the means.

And can be more confident in our conclusion about the difference between the two groups.

A) we would send Order A to Factory 3.

B) we would send both Order B and Order C to Factory 3.

B 7,000 Factory 3

C 30,000 Factory 3

Total number of units produced for the company today: 37,000

Average cost per unit for all production today: $9.00

To make decisions about which factory to send the orders to on Monday and Tuesday, we need to compare the costs per unit for each factory and consider the total number of units to be produced. Let's go through each day's scenario and make the production decisions.

a) Monday: Order A for 15,000 units

To decide which factory to send the order to, we compare the costs per unit for each factory. We select the factory with the lowest cost per unit to minimize the average cost per unit for the company.

Let's assume the costs per unit for each factory are as follows:

Factory 1: $10 per unit

Factory 2: $12 per unit

Factory 3: $9 per unit

To calculate the total cost for each factory, we multiply the cost per unit by the number of units:

Factory 1: $10 * 15,000 = $150,000

Factory 2: $12 * 15,000 = $180,000

Factory 3: $9 * 15,000 = $135,000

Based on the calculations, Factory 3 has the lowest total cost for producing 15,000 units, with a total cost of $135,000. Therefore, we would send Order A to Factory 3.

b) Tuesday: Order B for 7,000 units and Order C for 30,000 units

We have two options: sending each order to a separate factory or sending both orders to the same factory. We need to compare the average cost per unit for each option and select the one that results in the lowest average cost per unit.

Let's assume the costs per unit for each factory remain the same as in the previous example. We will calculate the average cost per unit for each option:

Option 1: Sending orders to separate factories

For Order B (7,000 units):

Average cost per unit = ($10 * 7,000) / 7,000 = $10

For Order C (30,000 units):

Average cost per unit = ($9 * 30,000) / 30,000 = $9

Total number of units produced for the company today = 7,000 + 30,000 = 37,000

Average cost per unit for all production today = ($10 * 7,000 + $9 * 30,000) / 37,000 = $9.43 (rounded to two decimal places)

Option 2: Sending both orders to the same factory (Factory 3)

For Orders B and C (37,000 units):

Average cost per unit = ($9 * 37,000) / 37,000 = $9

Comparing the two options, we see that both options have the same average cost per unit of $9. However, sending both orders to Factory 3 simplifies the production process by consolidating the orders in one factory. Therefore, we would send both Order B and Order C to Factory 3.

Production Report for Tuesday:

Order # of Units Factory

B   7,000      Factory 3

C  30,000    Factory 3

There are 36 '5' letter words that can be formed from the letters of "formulated" with 2 vowels, 3 consonants, and a vowel at the end.

Here, we have,

The word "formulated" has 4 vowels and 6 consonants. If each 5 letter word must contain 2 vowels and end with a vowel, there are two options for the last letter, "e" or "a". To form a 5 letter word with 2 vowels and 3 consonants, we need to choose 2 vowels from the 4 vowels in "formulated" and 3 consonants from the 6 consonants in "formulated". The order of the chosen letters does not matter, as we will arrange them later.

Thus, we can use the combination formula to find the number of ways to choose the vowels and consonants: C(4, 2) * C(6, 3) = 6 * 20 = 120.

Finally, we need to arrange these 5 letters in a specific order: consonant-consonant-vowel-consonant-vowel.

There are 3 choices for the first consonant, 2 choices for the second consonant (since it cannot be the same as the first), 2 choices for the vowel (either "e" or "a"), 3 choices for the third consonant (since it cannot be the same as the first or second), and 1 choice for the final vowel.

Thus, the total number of 5 letter words that can be formed from the letters of "formulated" with 2 vowels, 3 consonants, and a vowel at the end is 3 * 2 * 2 * 3 * 1 = 36.

Number of ways to select 8 countries from the United Nations is 48,054,722,400

To solve this problem, we need to use the combination method, which states that if there are m ways to perform one task and n ways to perform another task after the first task is completed, then there are m x n ways to perform both tasks in sequence.

Using this principle, we can break down the selection of 8 countries into three separate tasks

Selecting 3 countries from a block of 52: There are 52C3 ways to do this, where 52C3 is the binomial coefficient "52 choose 3," which can be calculated as follows

52C3 = (52 x 51 x 50) / (3 x 2 x 1) = 22,100

Selecting 2 countries from a block of 64: There are 64C2 ways to do this, where 64C2 is the binomial coefficient "64 choose 2," which can be calculated as follows

64C2 = (64 x 63) / (2 x 1) = 2,016

Selecting 3 countries from a block of 73: There are 73C3 ways to do this, where 73C3 is the binomial coefficient "73 choose 3," which can be calculated as follows

73C3 = (73 x 72 x 71) / (3 x 2 x 1) = 1,082,790

To find the total number of ways to select 8 countries, we simply multiply these three quantities together

22,100 x 2,016 x 1,082,790 = 48,054,722,400

5 sqrt(5)

Answer:

5√(5)

Step-by-step explanation:

Notice that 125 is 25×5

If you couldn't do it use the prime factorization.

Prime numbers are 2,3,5.....

125 isn't divisible by 2 and 3 so we'll go with 5.

● 125 ÷ 5 = 25

Againg 25 is divisible by 5

● 25÷5 = 5

5 is divisible by 5

● 5÷5=1

So 125= 5×5×5 = 5^2 × 5

● √(125)= √(5^2×5) = 5√(5)

Here are the steps to solve this problem:

1. Find the area of each face of the ramp.

The rectangular base is 2 meters by 1.5 meters, so the area is 2 x 1.5 = 3 square meters.

The triangular side is 0.5 meters by 1.5 meters, so we use the area of a triangle formula: (base x height)/2 = (0.5 x 1.5)/2 = 0.375 square meters

2. Add the areas of the faces together to find the total surface area that needs to be covered.

3 + 0.375 = 3.375 square meters

3. We need an additional amount for overlaps where the vinyl pieces meet. Let's assume a 10% overlap, or 0.338 square meters.

0.338 + 3.375 = 3.713 square meters

So Mathias needs about 3.7 square meters of vinyl to cover his bike ramp.

In summary:

Area of rectangular base = 2 x 1.5 = 3m^2

Area of triangular side = (0.5 x 1.5)/2 = 0.375m^2

Total area = 3 + 0.375 = 3.375 m^2

Additional 10% for overlap = 0.338m^2

Total vinyl needed = 0.338 + 3.375 = 3.713 m^2
