work out the area of this trapezium
6cm
10cm
8cm
17cm

Answers

Answer:

  (81√15)/4 ≈ 78.43 cm²

Step-by-step explanation:

It can help to draw a diagram.

The base angle at the side of length 6 can be found using the Law of Cosines. Its opposite side is of length 8, and the two adjacent sides are of length 6 and 7. So, we have ...

  8² = 6² +7² -2·6·7·cos(α)

  cos(α) = (36+49-64)/(84) = 1/4

  α = arccos(1/4) ≈ 75.522°

Then the height of the trapezium is ...

  6·sin(75.522°) ≈ 5.80948 . . . . cm

__

The area of the trapezium is given by the formula ...

  A = 1/2(b1 +b2)h

  A = (1/2)(17 +10)(5.80948) . . . . cm²

  A ≈ 78.43 cm²

__

Of course, sin(arccos(1/4)) = (√15)/4, so the exact formulation of the area is ...

  A = (81√15)/4 cm²

Explain how your equations were affected by the sign of the ordered pair values (positive or negative).​

Answers

The first number in the ordered pair is the x coordinate. It describes the number of units to the left or right of the origin. The second number in the ordered pair is the y coordinate. It describes the number of units above or below the origin. To plot a point, start at the origin and count along the x axis until you reach the x coordinate, count right for positive numbers, left for negative. Then count up or down the number of the y coordinate (up for positive, down for negative.)

By how much does the outlier in the following data set increase the mean of the data set? Round your answer to the nearest hundredth if necessary.
{10, 12, 17, 18, 22, 30, 101}

I NEED THIS ANSWERED BEFORE 10 PM PST

Answers

Answer:   11.83

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

Explanation:

With the outlier, the mean is

m = (10+12+17+18+22+30+101)/7 = 30

I added up the values and divided by 7 since there are 7 values being added up.

Without the outlier 101, the mean is now

n = (10+12+17+18+22+30)/6 = 18.1667 approximately

We're dividing by one less item this time.

Subtract the values of m and n

m-n = 30-18.1667 = 11.8333

This rounds to 11.83

The large outlier 101 increases the mean by roughly 11.83

Any time the outlier is larger than the main cluster of values, the mean is pulled to be larger than it should be if we ignored the outlier. The further the outlier, the stronger the pull and the more skewed the mean will get.

Note how the median of {10,12,17,18,22,30} is 17.5 which is a better measure of center compared to m = 30 found earlier.

9.) A new basketball is $10.95 and is 20% off. The sales tax is 7%.

Answers

If you are trying to find the cost of the basket ball, it is $8.15.

Step 1: Find 20% of 10.95- which is 2.19- and subtract 2.19 from 10.95-which is 8.76.

Step 2: Find 7% of 8.76-which is 0.6132- and subtract 0.6132 from 8.76-which is 8.1468

Step 3: Round to the nearest hundredth, which gives you 8.15.

Thus, $8.15 is your answer.

A team of bakers can roll and form 5 dozen pretzels in 9 minutes. How many pretzels can this team form in 1 hour?

This team can form
pretzels in 1 hour.

Answers

Answer:

This team can form 400 pretzels in one hour

Step-by-step explanation:

How many pretzels in 9 minutes?

5(12)=60

Solve as proportion

60 pretzels = 9 minutes

x    pretzels = 60 minutes

60(60)=9x

3600=9x

Divide both sides by 9

x= 400 pretzels

This team can form 400 pretzels in 1 hour

Answer:

this team can form 30 pretzels in 1 hour

Step-by-step explanation:

60 minutes are in a hour, and 60 divided by 9 is 6.6. So that means you would have to use 6. So 9 x 6 equals 54. Now do 5 x 6 and that would equal 30.

StartFraction 2 StartRoot 3 EndRoot Over 3 EndFraction

Answers

Answer:

StartFraction StartRoot 3 EndRoot Over 3 EndFraction

Step-by-step explanation:

Find the diagram attached.

From the right triangle XYZ:

XY is the hypotenuse

XZ and YZ are opposite and adjacent

To get value of tan(Y), we will use the SOH, CAH, TOA, trigonometry identity.

According to TOA:

Tan(Y) = XZ/ZY

First let us get XZ

Using SOH

SinY = opp/hyp = XZ/XY

SinY = XZ/4

Sin30 = XZ/4

XZ = 4sin30

XZ = 4(0.5)

XZ = 2units

Next is to get ZY:

Using Pythagoras theorem:

ZY²+XZ² = XY²

ZY² = XY²-XZ²

ZY² = 4²-2²

ZY²  = 16-4

ZY²  = 12

ZY = √12

ZY = √4*3

ZY = 2√3

Solve for tan(Y):

Since Tan(Y) = XZ/ZY

Tan(Y) = 2/2√3

Tan(Y) = 1/√3

Rationalize

Tan(Y) = 1/√3*√3/√3

Tan(Y) = √3/√9

Tan(Y) = √3/3

Hence the correct option is A. StartFraction StartRoot 3 EndRoot Over 3 EndFraction

Kelvin Doe has all of these components in his life. From a small village in the Republic of Sierra Leone in West Africa, this teen changed the lives of the people in his community by his innovative approach to life.Kelvin Gets His StartMost teens could not imagine going to bed at 7 p.m. every night, but Kelvin would. Then, in the middle of the night, he would wake up to transform his living room. It was a small electronics scrapyard, as Kelvin explained. Kelvin was always very interested in technology and inventions, but he lived very poorly. His community did not have modern technology. This did not stop Kelvin. He scrounged through scrapyards and dumps looking for basic components to make his inventions work.The Beginning of ChangeThere was always an important piece missing for his inventions. He needed batteries to power his homemade devices. Kelvin did not have the benefit of a science education at school. Yet, he figured out how to make a battery using soda, metal, and tape. These are ingredients he found at a neighborhood dump! With this battery, the possibilities for his inventions were endless.Community ChangesOnce he had perfected the battery, he began to think of ways to improve the lives of the people in his community. One day a week, the government electricity would turn on in the village. The villagers had electricity to power up devices and use their simple light bulb only four times a month. The rest of the month, they were in the dark. Kelvin decided to make a bigger battery. He made a generator to power the homes in the village. Now, they only have to turn on the generators to enjoy the benefits of electric power.DJ FocusAlong with inventing, Kelvin Doe likes to listen to the latest music. His village, though, did not get dependable radio transmission. So, Kelvin melded his love of music and his interest in engineering. He built his own radio station. His teen friends work as reporters and station managers. He now goes by the moniker DJ Focus. I picked this name because if you focus, you can invent anything, explains Kelvin.His Future Looks Bright During a game, the pittsburgh steelers converted 6 of 10 fourths downs into first downs.
