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].

show steps
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

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.

Find the volume of the cone. Round to two decimal places
Answer:
564.44
11*7 squared
Answer:
V = 564.15 ft^3
Step-by-step explanation:
The formula for the volume of a cone of base radius r and height h is
V = (1/3)(pi)(r^2)(h). Here, r = 7 ft and h = 11 ft, and so the volume of this particular cone is
V = (1/3)(3.14)(7 ft)^2*(11 ft), or V = 564.15 ft^3

The table is filled out by following these steps:
Step 1) Pick any number you want for x. Usually small values work such as x = 0, but you can choose anything you want. Be sure it fits within the window of the graph.Step 2) Replace x with that number you picked. If you picked x = 0, then y = (1/3)x becomes y = (1/3)*0 = 0. Meaning x = 0 leads to y = 0. The point (0,0) is on the graph.Step 3) Go back to step 1 and repeat the process with other x values. I recommend picking multiples of 3 so you can avoid fractional values of y.Follow those steps listed above so you can fill out the table. Each row of the table generates a different (x,y) point on the graph. Then draw a line or curve through the points. In this case, it's a straight line.
This straight line has a slope of 1/3 because y = (1/3)x is in slope-intercept form y = mx+b where,
m = 1/3 = slopeb = 0 = y interceptA slope of 1/3 means "go up 1, over to the right 3" when hopping from point to point along the line.
The unit rate and slope are the same thing when it comes to linear equations.
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.
A book store is hosting a special night in which families can enjoy a story and craft time. Tickets to the
event must be purchased ahead of time and are $1.50 for children and $2.50 for adults. So far, 45
children's tickets have been sold, which is 60% of the total tickets sold. How many tickets have been
sold so far? Show your calculations or explain how you got your answer.
Answer:
75 total tickets
Step-by-step explanation:
METHOD 1:
We know that 45 children's tickets have been sold, being 60% of the total tickets having been sold.
So, basically, we solve for x:
We have, 60% × x = 45
or, 60/100 × x = 45
Multiplying both sides by 100 and dividing both sides by 60,
we have x = 45 × 100/60
x = 75
If using calculator, enter 45x100/60, which will give you the answer.
------------------------
METHOD 2:
Division is the opposite of multiplication
Start with the formula to calculate the percentage of total
y=value÷ percentage/100
Substitute values in the equation
y=45÷60/100
Simplify and solve
y=45÷0.6
y=75
Both methods give you 75, therefore 75 tickets have been sold

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
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
