Which figure is a trapezoid?

A 4-sided shape with 2 parallel sides.
A 4-sided shape with 4 parallel sides.
A 4-sided shape with 4 parallel sides.
A 5-sided shape with 2 parallel sides.

Answers

Answer 1

Answer:

none of those

Step-by-step explanation:

A trapezoid is a 4-sided shape with 1 parallel side

Could you pls choose this as brainliest???!!!

Answer 2
The answer would be a four sided shape with one set of parallel sides. Parallel sides are two sides that will never touch or intersect. To further explain, if we take the left and right sides of the trapezoids and extend them, they will eventually intersect meaning that they aren’t parallel. This will go for and trapezoid, no matter the side lengths. However, if we take the top and bottom sides of a trapezoid and extend them left and right, we will find that they will never intersect which is how we know that a trapezoid only has one pair of parallel sides.

11x+2=5x+10+58
show steps

Answers

x = 11

Step-by-step explanation:

=> 11x + 2 = 5x + 10 + 58

=> 11x - 5x = 10 + 58 - 2

=> 6x = 66

=> x = 66/6

=> x = 11

We are asked to solve the equation [tex]\large\pmb{11x+2=5x+10+58}[/tex].

[tex]\triangle~\fbox{\bf{KEY:}}[/tex]

The goal is to get x all by itself.

So here's how we solve the equation...

///\\\///\\\///\\\///\\\///\\\///\\\///\\\///\\\///\\\///\\\\///\\\///\\\///\\\///\\\///\\\///\\\///\\\

Notice that we can add 10 and 58 right off the bat:

[tex]\large\pmb{11x+2=5x+68}[/tex]

Now we subtract 2 from both sides of the equal sign:

[tex]\large\pmb{11x=5x+66}[/tex]

Now we subtract 5x from both sides of the equal sign:

[tex]\large\pmb{6x=66}[/tex]

Divide both sides by 6:

[tex]\large\pmb{11}[/tex]

That's the value of x.

Hope it helps you out! :D

Answer:

The slope is -5 and the y intercept is (0,4). (D).

Step-by-step explanation:

The formula for this is y=mx+b. With m equaling the slope, and b equaling the y intercept. In the place of m, there is -5, getting you your slope of -5 and in the place of b there is 4 (meaning the coordinate (0,4)), getting you your answer. I hope this helps! :)

so in order to find the surface are of square and rectangle we have this formula square =a^2


Some of the rectangles are 11*5 = 55

And for the squares they are 2*5=10


But we have 2 rectangle with 2*11=22

Mr. Perry took his family out to
dinner last night and their subtotal
was $88.24. The sales tax was 5%
and he left a 20% tip. If Mr. Perry
put $120 on the table, how much
change did he receive?

[Show Work Please]

Answers

Answer: $8.83

Step-by-step explanation:

Facts:

Total before extra fees: $88.24

Sales tax: 5%

plus a 20% tip afterwards.

Gave $120

Change= ?

___________

Step 1: Add the sales tax

The first thing to do is find 5% of 88.24, since the sales tax was 5% of the cost of their dinner.

5% of 88.24= 4.41200---> $4.40

Now we add it to the subtotal.

4.40+ 88.24= $92.64

Step 2: Add the 20% tip.

Since the question puts the "20% tip" statement  after the 5% tax, I'm going to assume that the 20% tip is 20% of the dinner cost after the tax was added.

So the new cost is 92.64. All you need to do is find 20% of 92.64, and then add the result to 92.64. Look:

20% of 92.64= 18.528--> $18.53

18.53+92.64= $111.17

Now, there we have the total cost of dinner.

Step 3: Find how much change he got.

So now we know the total cost is $111.17, and that he paid with $120. He obviously  paid more than the total cost, so to find the amount of change, simply subtract the 111.17 from 120:

120-111.17= $8.83

He recieved $8.83 in change because he paid $8.83 more than the expected balance (actual total cost).

Hope this helps :)) Also brainliest would be appreciated, i worked pretty hard on this :)

Answer:$8.82 Change

Step-by-step explanation:

88.24*1.20=105.89. 105.89*1.05=111.18

$120-$111.18=$8.82 change.

Answer:

4 miles per hour

Step-by-step explanation:

Unit rate is the rate of something per 1 unit. In other words, the unit rate is x units per 1 unit. In this situation, the unit rate is how many miles Hassan walks in 1 hour.

Proportion

First, to find the rate of anything we can set up a proportion. In the question, the rate is described as miles per hour, so the miles will be the numerator and the hours will be the denominator.

This creates the proportion [tex]\frac{12miles}{3hours}[/tex]

So, the rate we are given is 12/3.

Unit Rate

To find the unit rate we need to make the denominator equal to 1. To do this, divide both the numerator and denominator by 3.

12/3 equals 43/3 equals 1

So, this means that the new proportion is 4/1. Next, we can add our units, which means that Hassan walks 4 miles per 1 hour.

Graph

Now we can resize the bar graph. The purple bar should be set to 4 because this represents the miles. Then, the green bar should be set to 1 because it represents the hours.

4 miles per hour bc that's what the answer is

The answer is D, or (2, -2).

Explanation: The angles that would make up the top left and right corners of the parallelogram would be (4,0) and (2,0). Because (0, -2) is the bottom left angle, to make this shape a full parallelogram, the y-coordinate of the other angle would have to also be -2, and it would have to be to the right of the origin so the figure does not look sloppy. To add on to this, none of the given x-coordinates are negative, so the fourth point should not have a negative x-coordinate. That would instantly get rid of A, B, and C. Therefore, your answer would be D, or (0, -2).

What are the limitations of using the Fundamental Counting Principle when determining the probability of an outcome? Support your answers with an example.

Answers

Answer:

The fundamental counting principle is used to count the total number of possible outcomes that are in a situation.

What does the fundamental counting principle state?

The fundamental counting principle states that if there are n ways of doing something, as well as m ways of doing another thing, then there are n×m ways to perform both of these actions.

The Fundamental Counting Principle helps when determining the sample space of probability as it figures out the total number of ways the combination of events can occur. Therefore, it is used as a guide when determining the sample space of a probability.

Lastly, the limitation is that the Fundamental Counting Principle is that it assumes that each basic event is equally probable, which does not necessarily have to be true.
