Answer:

5√5

Step-by-step explanation:

the area of the triangle is, "base len x height"

the base in here is √1^2 + 2^2 = √5

its height is √4^2 + 3^2 = 5

Answers

Answer:

[tex]\frac{4}{6} =\frac{6}{9}= \frac{8}{12}[/tex]

Step-by-step explanation:

I'm assuming this is asking for 3 separate fractions that are each equal to 2/3

Remember, multiplying the top and bottom of a fraction by a number will not change the fraction.

[tex]\frac{2}{3} *\frac{2}{2} =\frac{4}{6}[/tex]

[tex]\frac{2}{3} *\frac{3}{3} =\frac{6}{9}[/tex]

(-11, 0)

Step-by-step explanation:

A (-9, -6)

translation: left 2 units, up 6 units

If the point is moving left, this will change the x value. We are moving left which is towards the negative side of the graph. This means we will be subtracting 2 from the x-value.

-9 - 2 = -11

This is our new x-coordinate.

If the point is moving up, this will change the y-value. We are moving up, which is towards the positive side of the graph. This means we will be adding 6 from the y-value.

-6 + 6 = 0

This is our new y-coordinate.

Let's put our new coordinates together.

(-11, 0)

This is your answer.

In a particular year, a total of 50,127 students studied in two of the most popular host countries when traveling abroad. If 8383 more students studied in the most
popular host country than in the second most popular host country, find how many students studied abroad in each country.
There were students who studied abroad in the most popular host country

Answers

Let x be the number of students in the SECOND most popular host country.
Let x + 8383 be the number of students in the most popular host country.

x + (x + 8383) = 50127
2x = 50127 - 8383
x = 41744/2
x = 20872

therefore, the number of students in the SECOND most popular host country is 20872 and the number of students in the most popular host country is 29255.

Find the length of the​ arc, s, on a circle of radius r intercepted by a central angle theta. Express the arc length in terms of pi. Then round your answer to two decimal places. ​Radius, r​ = 10 ​inches; Central​ angle, theta ​= 45 degrees

Answers

Answer:

arc = 2.5π

Step-by-step explanation:

the circumference of the circle is:

2(10)(π) = 20π

45°/360° = 1/8

A construction crew is lengthening a road that originally measured 44 miles. The crew is adding 1 mile to the road each day. The length, L (in miles), after d days of construction is given by the following function.
L(d)= 44+d
What is the length of the road after 35 days?

Answers

Answer:

The length of the road after 35 days is of 79 miles.

Step-by-step explanation:

The length of the road, after d days, is given by:

[tex]L(d) = 44 + d[/tex]

What is the length of the road after 35 days?

This is l when d = 35. So

[tex]L(35) = 44 + 35 = 79[/tex]

The length of the road after 35 days is of 79 miles.

A cell phone provider classifies its customers as Low users (less than 400 minutesper month) or High users (400 or more minutes per month). Studies have shownthat 80% of the people who were Low users one month will be Low users the nextmonth, and that 70% of the people who were High users one month will be Highusers the next month.
(a) Set up the 2x2 stochastic matrix with columns and rows labeled L and H that displays these transitions
(b) Suppose that, during the month of January, 50% of the customers were Low users. What percent of the customers will be Low users in February? In March? (Type an integer or decimal for each matrix element.)

Answers

1. The stochastic matrix for the given transitions is:

   [tex]T = \left[\begin{array}{ccc}0.80 & 0.20\\0.30&0.70 \end{array}\right]\\[/tex]

2. 40.0% people in February and 32.0% people in March will be the low  users if there are 50% low users in January.

It is given that,

80% of the people who were Low users one month will be Low users the next month.

That means for the transition low-low (L-L)

p = 0.80

So, for Low-high transition (L-H)

p = 1-0.80 = 0.20

It is also given that 70% of the people who were High users one month will be High users the next month.

That means, p = 0.70 for the transition high-high (H-H)

Then for H-L transition, p = 1-0.70 = 0.30

(a) The 2x2 stochastic matrix for these transitions is:

[tex]T = \left[\begin{array}{ccc}0.80 & 0.20\\0.30&0.70 \end{array}\right]\\[/tex]

(b) Given that 50% users are the low users in month of January.

[tex]\text{Percent of the customers will be Low users in February}= (\text{low users in month of January} \times \text{Probability of L-L transition.}) \times 100\%[/tex]= (0.50 x 0.80)x100%

= 0.4x 100%

=40.0%

Now, the percentage of people who will be low users in the month of march = (low users in February x probability of L-L transition)x100%

=(0.40x0.80)x100%

=0.32x100%

=32.0%

Hence, the percentage of people who will be low users in the month of February and in the month of March are 40.0% and 32.0% respectively.

Therefore, the results are:

1.2x2 stochastic matrix for the transitions is as:

         [tex]T = \left[\begin{array}{ccc}0.80 & 0.20\\0.30&0.70 \end{array}\right]\\[/tex]

2. The percentage of people who will be low users in the month of     February and in the month of March are 40.0% and 32.0% respectively.

A store gives customers a markup of 13%. If the store sells a belt for $25, what was the wholesale price paid for the belt by the store?

Answers

Answer:

$22.12

Step-by-step explanation:

Let x be the wholesale price (the price before adding the markup).

The markup is 13%, so 13% of x is added to x.

x + 13%x = $25

x + 0.13x = 25

1.13x = 25

x = 25/1.13

x = 22.12

In 1 month it rained 12 inches. Then it rained 3 inches per month for 9 months. How many inches did it rain in all?

Answers

Answer: 39

Step-by-step explanation: Just addition

Answer:

Total rainfall = 39 inches.

Step-by-step explanation:

The question is not properly qualified. I am assuming that the first month, 12 inches of rain fell (that is an awful lot) and for the next 9 months the rainfall was 3 inches per month.

Let R be the total rainfall.

R = first month + 9*3

R = 12 + 27

R = 39

I go and come with a strange liberty in Nature, a part of herself. As I walk along the stony shore of the pond in my shirt-sleeves, though it is cool as well as cloudy and windy, and I see nothing special to attract me, all the elements are unusually congenial to me. The bullfrogs trump to usher in the night, and the note of the whip-poor-will is borne on the rippling wind from over the water. Sympathy with the fluttering alder and poplar leaves almost takes away my breath; yet, like the lake, my serenity is rippled but not ruffled. These small waves raised by the evening wind are as remote from storm as the smooth reflecting surface. Though it is now dark, the wind still blows and roars in the wood, the waves still dash, and some creatures lull the rest with their notes. The repose is never complete. The wildest animals do not repose, but seek their prey now; the fox, and skunk, and rabbit, now roam the fields and woods without fear. They are Nature's watchmenlinks which connect the days of animated life. There is commonly sufficient space about us. Our horizon is never quite at our elbows. The thick wood is not just at our door, nor the pond, but somewhat is always clearing, familiar and worn by us, appropriated and fenced in some way, and reclaimed from Nature. For what reason have I this vast range and circuit, some square miles of unfrequented forest, for my privacy, abandoned to me by men? My nearest neighbor is a mile distant, and no house is visible from any place but the hill-tops within half a mile of my own. I have my horizon bounded by woods all to myself; a distant view of the railroad where it touches the pond on the one hand, and of the fence which skirts the woodland road on the other. But for the most part it is as solitary where I live as on the prairies. It is as much Asia or Africa as New England. I have, as it were, my own sun and moon and stars, and a little world all to myself.1What effect does the setting have on the author? A. He feels very irritated by the roaring wind. B.
