In the figure given below, calculate x and y.

Answers

Answer:

x = 73°

        y = 39°

Step-by-step explanation:

x + 107 = 180        {Linear pair}

        x = 180 - 107         {Subtract 107 from both sides}

        x = 73°

y + 51 + 90 = 180      {straight line angles}

   y  +  141   = 180

           y = 180 - 141

          y = 39°

x= 73. y=39. 180-107=73 and since it is a straight line the angle is 180. and 90-51= 39 because a right angle is 90 degrees and since the other side was a right angle that means that angle has to be a right angle too

CAN SOMEONE ANSWER THIS WITH THEIR OWN OPINION Should doctors be allowed to dress casually while at work? Why or why not? What is your opinion?

Answers

I say no, doctors should always come looking professional and ready to work, casual looks will make them blend in with the crowd .
i say no. they should wear their proper attire. if they wore casual clothing at work people and possibly coworkers would think they’re just patients or not an actual worker. this could lead to people that actually need help not coming up to them if it was needed. they should wear their proper attire in case of an emergency or in case they do not want to get their casual clothing dirty in some circumstances.

Write the equation of the line in slope-intercept form using y=mx+b​

Answers

Answer:

y = 4x + 4

Step-by-step explanation:

Two points you can see on the graph are (0,4) and (-2,-4)

Now, to find the slope, use delta y/ delta x

(-4-4)/(-2-0)

(-8)/(-2) = 4

Slope is 4.

y = 4x + b

Now, to find b, we need the y-intercept, which is the point where x is 0 and the graph crosses the y-axis.

This value is 4. So, the y-intercept is 4

Substitute into your equation

y = 4x + 4

Y=4x+4 !!!!!!!!!!!!!!!

Find the surface area of the triangular prism.

Answers

Answer:

First picture: 60

Second picture:

Step-by-step explanation:

The first step for the first picture is to find the area of the triangle on top. In order to do that, we have to use the equation: (W*L*1/2)

(3*4*1/2)=6

Then, we multiply the above equation by the Height. Which makes the equation become 60.

The first step for the second picture is the same. We first find the area of the triangle on top.

(12*9*1/2)=54

Then we multiply the height by our above answer.

(54*20)=1,080

The other measurements that were there aren't needed. So, next time, completely ignore them!

Hi i'd love to help! but what is this comprehension about?

a) Aryans learned to farm the fertile soils of the Indus River Valley, allowing their settlements to become more permanent.
b) This Indo-Aryan language is a combination with Persian, Arabic, and Turkic elements in its vocabulary, with the grammar of the local dialects. This brought a common language to be spoken in the churches. their language was influential and distinctive. It distinguished them from other races. Aryan is a term that can define a linguistic group, which is a group of people classified as speaking the same language, or can be defined as a race, which is a group of people who comprise of specific and distinct characteristic.
c) The Aryans were the warrior nomadic people that migrated to the Indian subcontinent with their influential culture, religion and language. Aryan culture played a vital role in sculpting Hinduism by influencing the religion with their epics, texts and religious ideologies. The Aryans mixed with the Dravidians to create the complex religion of Hinduism.
d) Prior to the Mauryan Empire (321 to 185 B.C.) there was no organized Aryan government with a class of bureaucrats that acted as administrators. Instead there were numerous ruling chieftains ( rajan ), who were like warlords. They ruled with the support of armies and militias. They were counseled by purohitas , shaman-like figures believed to possess magical powers. When large kingdoms emerged the purohitas served as the equivalent of archbishops and prime ministers for the rulers, performing ritual sacrifices and giving political counsel. Commoners showed respect by kissing the feet of their sovereigns.

what is the diameter of a circle with area of 113.04 square cm. use 3.14?


pls fast

Answers

Answer:

diameter of a circle = 12cm

Step-by-step explanation:

Area of a circle = πr²

113.04 cm² = πr²

First, search for radius (r) :-

r = √(113.04/π)

r = 6 cm

As diameter is equals to 2×radius

The diameter of a circle = 2 × 6cm

Final answer = 12 cm

Answer:

d≈12cm

Step-by-step explanation:

Using the formulas

A=πr2

d=2r

Solving for d

d=2A

π=2·113.04

π≈11.99696cm

Find the surface area of the triangular prism.

Answers

Answer:

Triangular prism 1:    132

Triangular prism 2:   828

Step-by-step explanation:

1) triangle+triangle+rectangle+rectangle+rectangle

A of triangle=3*4 divided by 2

12/2= 6

since there are 2 triangles we do 6*2= 12

A of rectangle 1= 10*5= 50

A of rectangle 2= 10*4= 40

A of rectangle 3= 10*3= 30

so SA of whole figure is 12+50+40+30= 132

2) triangle+triangle+rectangle+rectangle+rectangle

A of triangle=9*12 divided by 2

108/2=54

since there are 2 triangles we do 54*2=108

A of rectangle 1= 9*20=180

A of rectangle 2= 15*20=300

A of rectangle 3= 12*20= 240

so SA of whole figure is 108+180+300+240=828
