ABCD is a rectangle in which AD = (2x + 1) cm and DC = (3x - 2) cm. PQRS is a trapezium in which PQ is parallel to SR, PQ = (x + 2) cm, SR = (5x − 8) cm and the shortest distance between PO and SR is (4x – 11) cm. The area of ABCD is twice the area of PQRS. Write down an equation in x to represent this information and show that it simplifies to 18x²89x + 68 = 0.

which is faster: drive a car at a rate of 40 kilometers per hour or drive a car at a rate of 15 meters per second
Answer:
Step-by-step explanation:
Let's convert one of these measurements so that both measurements have the same units. 15 m/sec is equivalent to 0.015 km/sec, which in turn is equivalent to
0.015 km 3600 sec
--------- -------- ----------------- = 54 km/hr
1 sec 1 hr
This latter result (54 km/hr) is faster than (40 km/hr).

Daily Math Question
You can identify sample spaces for compound events using organized lists, tables, and tree diagrams. Which of the three methods do you find easiest to use? Which method is the most helpful? Why?
What is the definition of the Fundamental Counting Principle? What does this principle state? How can the principle be used to help you identify a sample space for a compound event? What are the limitations of using the Fundamental Counting Principle when determining the probability of an outcome? Support your answers with an example.
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.

What is the surface area?
Answer:
402cm
Step-by-step explanation:
middle rectangle: 10 * 12 = 120cm
top and bottom rectangles: the sides will be connected to the 8cm triangle, making their heights 8cm. 8 * 12 = 96cm
side triangles: (10 * 9) / 2= 45cm
120 + (2 * 45) + (96 * 2) = 402cm

Mrs. Hanger is painting the following picture of an H to hang in the entryway of her home. She has made the following scale drawing as her model. The scale used on the drawing is 1:6. On the scale drawing, H is centered on the page and is inches from the top, bottom, and sides of the drawing.
As you can see, the "H" is going to be painted brick red in the center of a rectangular beige background. This means the distance from the "H" to the top of the picture will be the same as the distance from the "H" to the bottom of the picture. Similarly, the distance from the "H" to the left side of the picture will be the same as the distance from the "H" to the right side of the picture. Finally, each segment of the "H" will have the same width.

11x+2=5x+10+58

Step-by-step explanation:
=> 11x + 2 = 5x + 10 + 58
=> 11x - 5x = 10 + 58 - 2
=> 6x = 66
=> x = 66/6
=> x = 11

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.

What is the volume of this prism?
A.) 72 ft³
B.) 80 ft³
C.) 84 ft³
D.) I don't know.
Answer:
The answer would be 72 feet. (A)
Step-by-step explanation:
To find the volume of the prism you would do length times width time height. That would be 4 times 3 times 6. 4 times 3 is 12 and 12 times 6 is 72, getting you your answer. I hope this helps! :)
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]
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:

A square pyramid on top of a rectangular prism. The rectangular prism has a length of 4 meters, width of 4 meters, and height of 4 meters. The square pyramid has triangular sides that have a height of 3 meters and side length of 5 meters. Compare the surface area of the composite figure to the surface area to the combined surface areas of the figures if they were separated. The composite surface area would be the surface area of the rectangular prism plus the surface area of the square pyramid considered separately. You should not count the pyramid’s as part of the composite figure’s surface area.
Answer:
The square pyramid by itself has a surface area of 55 meter[tex]s^2[/tex].
The rectangular prism by itself has a surface area of 96 meter[tex]s^2[/tex].

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 1So, 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.
