Which group contains triangles that are similar. im having a hard time
​

Answer:

63 units

Step-by-step explanation:

9514 1404 393

Answer:

Step-by-step explanation:

1. Add the rates in terms of houses per day.

  1/4 + 1/7 = (7+4)/28 = 11/28

Then the time required in terms of days per house is the reciprocal of this:

  28/11 = 2 6/11 . . . . days to paint a house, working together

__

2. Each hour, the vehicles separate by 55 -40 = 15 miles. Then the time required for a separation of 25 miles is ...

  time = distance/speed = (25 mi)/(15 mi/h_ = 5/3 h = 1 2/3 h

The vehicles will be separated by 25 miles after 1 2/3 hours.

Answer:

x = 2.2, y = 5.3

Step-by-step explanation:

This question is asking us to solve a system (find x and y). Because they give us that y = 1.5x + 2, then we can use this to substitute into the second equation.

9x + 4y = 41

9x + 4(1.5x + 2) = 41

Simplify.

9x + 6x + 8 = 41

15x + 8 = 41

Subtract 8 from both sides.

15x = 33

Divide both sides by 15.

x = 11/5 = 2.2

To find y, substitute x = 2.2

y = 1.5x + 2

y = 1.5 * 2.2 + 2

y = 3.3 + 2

y = 5.3

Now, we can double check to see if these two answers are right. Plug these numbers into the other equation (because to find y, we already used the first equation, so there is no need to check it, as it would just give us 5.3 = 5.3)

9x + 4y = 41

9 * 2.2 + 4 * 5.3 = 41

19.8 + 21.2 = 41

41 = 41

Thus, the answer is correct.

Answer:

i. Average velocity = 11.11 m/s

ii. Displacement of the bus is 20000 m due east.

Step-by-step explanation:

The displacement of an object is the distance covered towards a definite direction, while the velocity of an object is the rate of its displacement in a given time.

average velocity = [tex]\frac{displacement}{time taken}[/tex]

But,

20 km = 20 000 m

30 minutes = 30 x 60

                   = 1800 s

So that,

average velocity  = [tex]\frac{20000}{1800}[/tex]

                             = 11.1111

average velocity = 11.1 m/s

The displacement of the bus is 20 km due east.

Answer:

79200 feet is the volume of great wall.

Step-by-step explanation:

1 mile = 5280 feet

5280 feet × 15 feet = 79200

The height is the thing that we don't need to use, because you need volume, volume is the place where the wall at, the place is 79200 feet.

And I have question for you, have you ever go to China, did you go to the great wall, where did you come from.

So a 1-mile section of the Great Wall of China has a volume of 1,584,000 cubic feet.

Volume is a measure of the amount of space occupied by a three-dimensional object or substance. It is typically measured in cubic units such as cubic meters, cubic centimeters, or cubic feet.

The volume of an object is determined by measuring the length, width, and height of the object and then multiplying these three dimensions together.

To calculate the volume of a 1-mile section of the wall, we need to first calculate the area of the wall in square feet, and then multiply it by the length of the 1-mile section.

The area of the wall can be calculated as the product of its height and width:

Area = Height x Width = 20 feet x 15 feet = 300 square feet

To convert the 1-mile distance to feet, we need to multiply it by the number of feet in a mile:

1 mile = 5280 feet

Therefore, the volume of a 1-mile section of the wall can be calculated as:

Volume = Area x Length = 300 square feet x 5280 feet = 1,584,000 cubic feet

So a 1-mile section of the Great Wall of China has a volume of 1,584,000 cubic feet.

Answer:

m∠4 = m∠1 + m∠3

Step-by-step explanation:

The measure of an exterior angle of a triangle is equal to the sum of its two opposite interior angles

Now, examining the given triangle, we can note that:

∠4 is an exterior angle

∠1 and ∠3 are its two opposite interior angles

Based on the givens and the above theorem, we can conclude that:

m∠4 = m∠1 + m∠3

Answer:

the area of the front face would be 40 square inches.

Step-by-step explanation:

to find the are of a rectangle, you multiply the length times the width. we can see that the length is 8 inches at the bottom of the front face and we can see that width is 5 inches next to the left side face. if we take those two numbers (5 and 8) and multiply them, we get 40. all you have to do after that is add "square inches" to the end because when you find the area of something, it will be squared and the measurement used in inches.

Answer:

C. A clothing store claims that 45% of its customers prefer skinny jeans over regular jeans. They concluded this from a survey which asked 120 randomly selected teenage customers which style they prefer.

E. A report by a company that manufactures hair brushes says 56% of people who buy their brushes own only one hair brush. The conclusion comes from a survey of 500 males who bought the company's brush.

Step-by-step explanation:

These two are the biased reports because they don't include the full population.

C is biased because it only includes teens, not people of any other age.

E is biased because it only included males, not females.

A isn't biased because it includes the stated population, high school students in the city.

B isn't biased because the sample was of 50 random customers, which is the general population.

D isn't biased as it included all data from the website.

Hope this helps!

The solution is,:

1) A clothing store claims that 45% of its customers prefer skinny jeans over regular jeans. They concluded this from a survey which asked 120 randomly selected teenage customers which style they prefer.

3) A report by a company that manufactures hair brushes says 56% of people who buy their brushes own only one hair brush. The conclusion comes from a survey of 500 males who bought the company's brush.

A portion of population taken and analyzed to predict information about population is called sample of that population.

Ex: When someone surveys a group, then he/she surveys a portion and not whole population in general.

Those numbers who summarize information about sample are called statistic.

(Statistic is different than statistics)

The  numbers which summarize information about the sample are called statistic.

The scenarios in which the statistics are misleading;

1) A clothing store claims that 45% of its customers prefer skinny jeans over regular jeans. They concluded this from a survey which asked 120 randomly selected teenage customers which style they prefer.

3) A report by a company that manufactures hair brushes says 56% of people who buy their brushes own only one hair brush. The conclusion comes from a survey of 500 males who bought the company's brush.
