Can someone tell me what x and y would be

Answers

Answer 1

Step-by-step explanation:

20°+120°+I°=180°

I=40°

using sine rule,

I/sin I=x/sinX

12/sin40=x/sin20

x=12sin20/sin40

x=6.4

using similarly and enlargement,

we have, cw/cp=y/120

8/12=y/120

y=80°

Goran needs to buy plastic forks. Brand A has a box of 12 forks for $1.12. Brand B has a box of 25 forks for $2.69.
Find the unit price for each brand. Then state which brand is the better buy based on the unit price.
Round your answers to the nearest cent.

Answers

Brand A 1.12/12 = .093 rounds to .09 cents each.
Brand B 2.69/25 = .1076 rounds to .11 cents each
Brand A is the better buy because it is cheaper

Find the median of 6,2,0,1,1,2,3,2,0,2,3,4,2,3,5

Answers

The median is 2
Median = Middle

First, arrange the numbers from lowest -> highest

This would be:
0, 0, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 4, 5, 6

Now, strike off one number from each side (so 0, then 6, then 0, then 5) until you are only left with one or two numbers.

If you are left with one number, that is your median!

If you are left with two numbers, than you add them together, then divide that number by 2 (for example if you were left with 7 and 8, 7+8=15. 15/2=7 1/2)

In this case, you are left with one number, 2, so 2 is your median.
I hope this helped!

Answer:

Step-by-step explanation:

The median is the middle number when the numbers are lined up from least to greatest or greatest to least.

First, the numbers must be lined up from least to greatest.

0, 0, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 4, 5, 6

Then, find the middle number.

The middle number is 2.

Working together, two pumps can drain a certain pool in 6 hours. If it takes the older pump 15 hours to drain the pool by itself, how pump to drain the pool on its own?

Answers

Answer:

Step-by-step explanation:

Rate of drainage for pump A and B = [1 pool drained]/[6 hours]

Rate of drainage for pump A (older pump) = [1 pool drained]/[15 hours]

Rate for pump B (newer pump) = [1 pool drained]/[t hours]

Thus, adding the rate of drainage of A and B,

1/t + 1/15 = 1/6

t=10

The slope of a line is 1/3.
What is the slope of a line perpendicular to this line?

Answers

Answer:

-3

Step-by-step explanation:

Slopes of a perpendicular line are the opposite reciprocal.

So, the opposite of 1/3 is -1/3.

Then the reciprocal of -1/3 is -3 (since -3 is -3/1).

Answer: 3

arc WS = arc VU + arc TU = 113 degrees

arc ST = arc WV because their chords cross making a pair of vertical angles.

full circle = 360 degrees

360-113 - 113 = 134 degrees

134/2 = 67 degrees for arc ST

arc STU = 67 + 53 = 120 degrees

Angle UXS = 120 degrees

4) arc CB = arc FB = 40 degrees because their chords cross making a pair of vertical angles.

Step-by-step explanation:

OKAY JUST A DISCLAIMER:

I did Geometry last year and the concepts are basically gone but I think I remember how to do this one

So I think one of the theorems stated that the inner angle is half of the outer arc.

So.. angle a would be 56/2 = 28

Angle b would be 94/2 = 47

Angle C is a vertical angle to the angle in the triangle, so it would be 180-47-28=105

plz help, Randy is fencing off a semi-circular region in his backyard against a wall. The semi-circular region has a diameter of 24 feet. The fencing will go along the arc only. How much fencing does Randy need?

Answers

Answer:

[tex]Fence = 41.408ft[/tex]

Step-by-step explanation:

Given

[tex]d = 24ft[/tex]

Required

Determine the length of the wall

First, we calculate the circumference (C) of the semi-circle

[tex]C =\pi d[/tex]

[tex]C = 3.142 * 24[/tex]

[tex]C = 75.408[/tex]

The length of the fence is calculated by subtracting the diameter from the circumference:

[tex]Fence = C - d[/tex]

[tex]Fence = 75.408ft - 24ft[/tex]

[tex]Fence = 41.408ft[/tex]

These tropical cyclones all form the same way. They form above warm ocean waters near the equator and use warm, moist air as fuel. This fuel allows them to continue to grow and rotate at faster speeds until they hit land. Once they hit land, they usually slow down because they no longer have the warm, moist air to fuel them. Although they slow down, they still move at speeds that allow them to cause great damage.Hurricane Irma is a recent storm that touched down in the United States, forming from a tropical wave in the Atlantic Ocean. This wave lead to rain showers and thunderstorms, and eventually, the showers and thunderstorms became organized into a system. This created a low pressure area, allowing a hurricane to form. Hurricane Irma continued to grow as it moved across the ocean. By the time it hit the Caribbean, it was a Category 4 hurricane. It continued to change in size and speed. Finally, it touched down in Florida as a Category 4 hurricane before gradually weakening in power and dying in Missouri.Hurricanes are a severe weather occurrence. Some hurricanes stay small, while others become more powerful until they touch down on land and start to lose power. However, hurricanes can still be catastrophic once they make landfall. Because scientists have learned so much about how hurricanes form, they are able to monitor them and warn people to take precautions if a hurricane hits in their area.Based on the information in the text, why is it important for scientists to inform the public about the category of a hurricane that is going to hit a specific area?Question 1 options:Scientists can warn the public about how powerful the hurricane will be and how much damage it may cause, which allows people to prepare.Scientists need to warn the public about the category so that the people from the area it hits can compare it to other hurricanes they have experienced.Scientists travel to different sites of hurricanes and want to inform the people from the area that they are collecting information about the hurricane.Scientists collect information about each category of hurricane and want to learn about the effects of the hurricane from the people in the community.
