Answer:

AB = 42.30 m

Step-by-step explanation:

What we are asked to do is to simply find the length of AB.

Since both triangles are similar, therefore their corresponding sides would be proportional to each other.

Thus:

92/82.8 = 47/AB

Cross multiply

92*AB = 82.8*47

92*AB = 3,891.6

AB = 3,891.6/92

AB = 42.30 m(nearest hundredth)

Answer:

2.9

Step-by-step explanation:

You can find this answer two different ways.

First, you can turn the percent into a decimal, multiply the two numbers, and add them together. (0.16 * 2.5) and then (0.4 + 2.5)

Second, you could find the decimal and add it to 1.0 so you get 1.16 and multiply by 2.5. (1.16 * 2.5)

627 x 26 equals 16,302 when solved using the standard algorithm.

The steps below can be used to solve the multiplication issue 627 x 26 using the conventional algorithm:

627 and 26 should be written one above the other, with the larger number appearing above and the smaller number beneath.

Start by adding each digit of the top number to the ones digit of the bottom number (six). Write the answers below the line after multiplying 6 by 7 and then by 2.

1254 -- a 6 x 7 partial product

1254 -- a half 6 x 2 product

Repeat the process by moving the bottom number one position to the left after that. Multiply 2 by 7 and then by 2, and then write the results one space to the left of the line below the line.

Answer:

The 3.907 is approximate.

====================================

Explanation:

x = number of hours that elapse

y = f(x) = number of tokens

If we use a graphing tool like a TI84 or GeoGebra, then the approximate solution to -3(2)^(x+1) + 90 = 0 is roughly x = 3.907

At around 3.907 hours is when the number of tokens is y = 0. Therefore, this is the approximate upper limit for the domain. The lower limit is x = 0.

The domain spans from x = 0 to roughly x = 3.907, and we shorten that down to 0 ≤ x ≤ 3.907

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

Plug in x = 0 to find y = 84. This is the largest value in the range.

The smallest value is y = 0.

The range spans from y = 0 to y = 84, so we get 0 ≤ y ≤ 84

Keep in mind y is the number of tokens. A fractional amount of tokens does not make sense, so we must have y be a whole number 1,2,3,...,83,84.

The x value can be fractional because 3.907 hours for instance is valid.

a.) Exact result: 10.9375. Approximate: 11 quarts of heavy cream.

b.) Exact result: 65.625. Approximate: 66 eggs.

c.) Exact result: 43.75. Approximate: 44 lemons.

If 400 guest will consume 1.75 pastries, then the total of pastries is:

\(400*1.75=700\)

If one quarter of the pastries will have 2 ounces of lemon filling, then the amount of pastries that will ahve this filling is:

\(700*\frac{1}{4}= 175\)

If 175 will have 2 ounces of lemon filling, then the ounces of lemon filling needed is:

\(175*2=350\)

Then, the mass, in pounds, of lemon filling needed is:

\(350/16=21.875\)

To find the quarts of heavy cream needed, set up a rule of 3 like this:

2 pounds of filling ------------ 1 quart of heavy cream

21.875 pounds of filling ----- x

\(x= \frac{21.875*1}{2} =10.9375\)

The amount of quarts of heavy cream needed is, approximately, 11.

Do the same rule of 3 as in question 1, except that now we substitute the ingredient and que quantity:

2 pounds of filling ------------ 6 eggs

21.875 pounds of filling ----- x

\(x= \frac{21.875*6}{2} =65.625\)

The amount of eggs needed is, approximately, 66.

First, let's find out how many cups of lemon juice are needed through a rule of 3.

2 pounds of filling ------------ 1 cup of lemon juice

21.875 pounds of filling ----- x

\(x= \frac{21.875*1}{2} =10.9375\)

Now, convert the cups to ounces.

10.9375 cups * 8= 87.5 ounces.

Set up another rule of 3 to determine the number of lemons.

2 ounces ------------ 1 lemon

87.5 ounces ----- x

\(x= \frac{87.5*1}{2} =43.75\)

The amount of lemons needed is, approximately, 44.

The standard form of a circle is (x - c)² + (y - d)² = r² where (c, d) is the center and r is the radius. This means that the center is (0, -7) and the radius is 8.

Answer:  Center = (0, -7)

                Radius = 8

Step-by-step explanation:

The equation of a circle is: (x - h)² + (y - k)² = r²     where

       x²   + (y + 7)² = 64

→   (x - 0)² + (y - (-7))² = 8²

We have to use the slope formula.

Let's replace the points (-5, 10) and (3, -4).

Based on the limited information provided, it is not possible to definitively determine the type of economy in Country A. More specific details and factors would be necessary to make a conclusive determination.

The average rate of change (slope) is 579.875 if, in 2009, there were 12,078 Burger King restaurants; in 2017, there were 16,717 Burger King restaurants.

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

\(\rm m =\dfrac{y_2-y_1}{x_2-x_1}\)

We have:

In 2009, there were 12,078 Burger King restaurants; in 2017, there were 16,717 Burger King restaurants.

The slope:

\(\rm m =\dfrac{16717-12078}{2017-2009}\)

m = 4639/8

m = 579.875

Thus, the average rate of change (slope) is 579.875 if, in 2009, there were 12,078 Burger King restaurants; in 2017, there were 16,717 Burger King restaurants.

keeping in mind that parallel lines have exactly the same slope, let's check for the slope of the equation above

\(3x+y=5\implies y=\stackrel{\stackrel{m}{\downarrow }}{-3}x+5\qquad \impliedby \qquad \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array}\)

so we're really looking for the equation of a line that has a slope oif -3 and it passes through (2 , -4)

\((\stackrel{x_1}{2}~,~\stackrel{y_1}{-4})\hspace{10em} \stackrel{slope}{m} ~=~ - 3 \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-4)}=\stackrel{m}{- 3}(x-\stackrel{x_1}{2}) \implies y +4 = - 3 ( x -2) \\\\\\ y+4=-3x+6\implies {\Large \begin{array}{llll} y=-3x+2 \end{array}}\)

Answer:

The expected total amount of time the operator will spend on the calls each day is of 210 minutes.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:

\(Z = \frac{X - \mu}{\sigma}\)

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

n-values of normal variable:

Suppose we have n values from a normally distributed variable. The mean of the sum of all the instances is \(M = n\mu\) and the standard deviation is \(s = \sigma\sqrt{n}\)

Calls to a customer service center last on average 2.8 minutes.

This means that \(\mu = 2.8\)

75 calls each day.

This means that \(n = 75\)

What is the expected total amount of time in minutes the operator will spend on the calls each day

This is M, so:

\(M = n\mu = 75*2.8 = 210\)

The expected total amount of time the operator will spend on the calls each day is of 210 minutes.

Option D is the correct answer.

From the graph, we can conclude that,

1. The two lines are continuous lines and not broken lines. So, the inequality sign should be either ≤ or ≥.

2. The points on the lines of the shaded region are also included in the solution.

The only option that matches with the above conditions is option D. So, option D is the correct answer.

Let us verify it.

Now, let us consider a point that is inside the shaded region and also on any one line.

Let us take (0, 2).

Plug in 0 for x and 2 for y in each of the options and check which inequality holds true.

Considering the inequalities,

y ≥ 3x - 2

x + 2y ≤ 4

Solving we get,

2 ≥ 3(0) - 2

2 ≥ -2

x + 2y ≤ 4

0 + 2(2) ≤ 4

4 ≤ 4

Here, both inequalities are correct.

So, option D is the correct answer.
