All four arms of a mechanical jack are the same​ length, and they form a parallelogram. Turning the crank pulls the arms​ together, raising the top of the jack. How high is the top of the jack when the crank is 5 inches off the​ ground? Explain.

Answers

Answer 1

Answer:

10 inches

Step-by-step explanation:

Answer 2

The top of the jack is 10 inches from ground.

What is parallelogram?

A parallelogram is a two-pair quadrilateral with parallel sides. A parallelogram has opposite sides that are the same length and have opposite angles that are the same size. Additionally, the interior angles on the same transversal side are supplemental. 360 degrees are the sum of all the interior angles.

A parallelepiped is a three-dimensional shape with parallelogram-shaped faces.

Given Jack is in shape of parallelogram,

height of crank of jack from ground  = 5 inches

to find the distance from ground to top of jack

since crank is at centre of jack and bottom  to top of jack makes the diagonal of parallelogram,

distance from crank to top of jack is 5 inches,

because The two diagonals cut across one another. The parallelogram is divided into two congruent triangles by each diagonal.

total length from ground is 5 + 5 = 10 inches

Hence length from ground to top of jack is 10 inches because diagonals bisect each other.

These triangles are similar triangles, so there is a number that you can multiply the sides of TUV to find the side lengths of QRS. looking at the triangle, the similar sides are RS being similar to UV and RQ being similar to UT.

If RS~UV, then there is a ratio between them. 54/36=1.5. The ratio is 1.5.

RQ~UT, and by a factor of 1.5, so divide RQ by the scale factor. 24/1.5=16. UT=16=x+5.

x+5=16, subtract 5 from both sides.

x=11

The Sognefjord is the deepest fjord in Norway at 1,308 metres (4,291 ft) If a submersible floating on the surface was to dive vertically at a rate of 35 meters a minute, how many minutes would it have been diving when it reached a point 48 meters from the bottom of the fjord?

Answers

Answer:

36 minutes

Step-by-step explanation:

Depth of the fjord = 1308 m

Rate at which the submersible dives = 35 meters/minute

Distance to the bottom of the fjord should be 48 m

Distance the submersible has to go underwater is [tex]1308-48=1260\ \text{m}[/tex]

Time is found by dividing the distance the submersible has to go underwater by rate at which the submersible dives

[tex]\dfrac{1263}{35}=36\ \text{minutes}[/tex]

The time taken by the submersible to dive the required distance is 36 minutes.

Base fare of taxi is $5.

Per mile cost is $2.50.

Your total cost is  where x is the number of miles. Since you're on a budget of maximum $20, the cost should be less than or equal to $20. We can write:

To find how many miles we can write, let's solve the inequality:

Shelter A has 500 beds and is 90% occupied. Shelter B is 60% occupied, the ratio of beds in Shelter A to Shelter B is 15:16

Answers

Answer:

800 beds

Step-by-step explanation:

Shelter A has 500 beds and is 90% occupied.

Number of occupied beds:

500*0.9 = 450

The ratio of beds occupied in Shelter A to Shelter B is 15:16

450/x = 15/16x = 450*16/15x = 480

Number of occupied beds in Shelter B is 480 which is 60% of total. Total number of beds is:

480/0.6 = 800

Answer:

Answer:there are 900 beds in shelter B

Step-by-step explanation:

Shelter A has a capacity of 300 beds and is 80% occupied. This means that the number of beds in Shelter A that would be

80/100 × 300 = 0.8 × 300 = 240 beds.

Let x represent the capacity of Shelter B. Shelter B is 45% occupied. It means that number of beds in Shelter B that would be occupied is

45/100 × x = 0.45 × x = 0.45x beds.

Total occupancy of shelter A and shelter B would be

240 + 0.45x

The ratio of the occupancy of shelter A to shelter B is 16:27

Total ratio of occupancy = 16 + 27 = 43

Therefore

27/43 × (240 + 0.45x) = 0.45x

27(240 + 0.45x) = 0.45x × 43 = 19.35x

6480 + 12.15x = 19.35x

6480 = 19.35x - 12.15x = 7.2x

x = 6480/7.2 = 900

In a recent year, 23.7% of all registered doctors were female. If there were 54,400 female registered doctors that year, what was the total number of registered doctors? Round your answer to the nearest whole number.

Answers

Answer:Total number of registered doctors=229, 536

Step-by-step explanation:

Let the total number of registered doctors be represented as x

Such that 23.7 % of female registered doctors is  totals  54,400

To find the total number of registered doctors, we use the equation

23.7%  x -= 54,400

Solving the equation we have

0.237 x x= 54,400

x= 54,400/0.237

x= 229, 535.86 rounded to 229, 536

x=Total number of registered doctors=229, 536

x = 7; y = 11

Step-by-step explanation:

AB = x

AB = CD

CD = 7 so....

x = 7

AD = y + x

AD = BC

BC = 18 so...

y + x = 18    

y + 7 = 18                        subtract 7 from 18

y = 11

Answer:

x = 7

y = 11

Step-by-step explanation:

Do you see those little arrow marks? Those indicate that if a side has those marks, they have the same length. If a side with one arrow is 7 units long, then it means that x = 7, because the side with x also has one arrow. Then, just plug in 7 into the y+x equation, and set it equal to the other side. (18).

y + 7 = 18; subtract 7 from both sides, to get x = 7; y = 11.

The sum of the numbers 18 and 27 will be 45.

What is the greatest common factor?

The largest factor of the two numbers which divides both the numbers is called as greatest common factor or GCF. The greatest common multiple is the common number multiplied by both numbers.

The distributive property of binary operations in mathematics generalizes the distributive law, which states that in elementary algebra, equality is always true.

Given sum is 18 + 27. The greatest common multiple between the two numbers is 9 take it common and then solve.

E = 18+27

E =9(2+3)

E =9(5)=45

Follow your instructors directions for finding a small group.In your group, take turns presenting your topic. Report your two facts and why the topic is interesting to you. When it is not your turn to present, pay attention to the other topics. Ask questions and discuss.Your research guide has space to record notes on your discussion. As a group, decide what topic to research and present on. Each person will need to decide to search and find a primary source and a secondary source on the topic.Independent ResearchThis May HelpSocial media is considered a primary source. The topic you are researching may be current enough that you can find comments and information posted on social media sites. If this is the case, you can consider using such information as a source and even cite it for your presentation. You will need to be careful, however. If you use information from a social media site, first, be certain that it is appropriate. Such information will also need to be relevant. For instance, a young person complaining about air pollution would not be effective as a source, but a government official or scientist giving an opinion and data on air quality would be.On your own, conduct research on the groups decided topic. You will be responsible for finding information from one primary and one secondary source.A primary source is an original document or artifact that comes from the period of time being studied. Someone from that time period actually wrote, created, or used the object the historian is studying.Examples of primary sources are diaries, letters, oral histories, and eyewitness accounts.Secondary sources are documents written after the event occurred. They provide a secondhand account of the event or topic. Secondary sources often contain more analysis, or even conclusions, about the events or topics discussed.Examples of secondary sources are newspaper and journal articles, academic textbooks, encyclopedias, reference books, and other non-fiction books and Web sites.When searching for information, your two sources, primary and secondary, should support each others claim. With two sources making the same claim, you can be more certain that the information is accurate.Fill in your research guide with the information you have found.Group Discussion: Creating a HypothesisOnce independent research is complete, return to your group with the information you have collected. Compare your findings, and begin discussing what you have learned about the geographical issue the group identified. Be sure to take turns sharing what you find.
