Hello! answer: the area is 528
Step-by-step explanation:
When finding area you should split the shapes up so forst im going to do the two sides that are the same those are just simply 10 x 12 = 120 10 x 12 = 120 So i add those up and get 240 I'll add this with the other sides later now Im going to do the front face thats a square that is 16 x 12 = 192 Now I'm just going to do the triangles that is 16 x 6 = 96 then I divide by 2 cause thats the formula for finding triangle area now I have 48 but since there are two of those triangles ill just do 48 x 2 = 96 now that I have All the faces im going to add them all up so... 240+ 192 + 96 = 528 Hope this explains well!

the sides of a rectangle are in the ratio 2:5. if the longer side of the rectangle is 25.5 in., what are it's width, perimeter, and area ?
Answers
Answer: The width of the rectangle is 10.2 inches, the perimeter is 71.4 inches, the area is 260.1 inches.
Step-by-step explanation:
25.5/5=5.1
5.1*2=10.2
The width is 10.2 inches
25.5*2+10.2*2=71.4
The perimeter is 71.4 inches
20.5*10.2=260.1
The area is 260.1
Width=10.2 in. Perimeter=71.4 in. Area=and 260.1 in.

What is the scale factor of the dilation?
Is the dilation an enlargement or a reduction?
Answers
Answers:
Scale Factor = 3/4
This is a reduction
======================================================
Explanation:
Let's focus on the point R(4,4). That's the preimage point for the image of R ' (3,3).
Let k be the scale factor. We multiply this value of k by the x,y coordinates of point R to jump to R '
we have x = 4 jump to 4k which is the x coordinate of point R'
So we set 4k equal to 3 and solve for k to get k = 3/4. The scale factor is 3/4 or 0.75
We have a reduction since the image triangle T'R'S' is smaller compared to the preimage triangle TRS. We can see that we have a reduction by looking at the scale factor. If 0 < k < 1, then we have a reduction. If k > 1, then we have an enlargement instead. So we go with the first option since 0 < 3/4 < 1 or you could say 0 < 0.75 < 1.
Answer:
A reduction (think shrinking) is a dilation that creates a smaller image, and an enlargement is a dilation that creates a larger image

What is the median of these numbers :
90, 95, 92, 93, 91, 97
Answers
Answer:92.5
Step-by-step explanation:
The middle numbers are 92 and 93 and then you add 92+93=185 and 185/2=92.5
Work :
1) Place the numbers in order
90, 91, 92, 93, 95, 97
2) There are two medians (92 & 93)
3) Add both numbers then divide by 2, because it’s two numbers and you need 1 median
92+93 = 185/2 = 92.5
Can someone give me a small lesson on nets and surface areas??
Thank you if you can. I really don’t understand.
Answers
Hi!
Here is the definition of a net from www.icoachmath.com:
“Net is a two-dimensional pattern of a three-dimensional figure that can be folded to form the figure. In other words, net is a flattened three-dimensional figure which can be turned into the solid by folding it.”
In the photo is an example of a net of a rectangular prism.
Surface area is the measure of the total area of the surface of a 3D object. For example, if I have a cube, the surface area would be the area of the outside of the cube.

5) No, it is not because the sizes of each section are not even.
6) Yes, this is fair since there are a even chance of getting each number.
7) 3 out of 25 or 3/25
8) The bag with 250 colored tiles would give him a less chance of picking a blue tile. In the first bag, there is a 40% chance that Greg would pick a blue tile while the second bag, he would have a 30% chance of picking a blue tile. To get these percentages, I divided the the amount of blue tiles in the bag by the total amount of tiles.
Explantion for question 8: 10 blue tiles in a bag of 25 so you would do 10/25 which is .4 and as a percentage it would be 40%. For the second question, 75 blue tiles out of 250 total so 75/250 and that would be .3 and as a percentage, it would be 30%. The "/" is a fraction bar and is sometimes used as a division symbol as well, just in case you don't know:)

The figure shows a trapezium PQRS where RS = 17m and PS = 15m. If PT = 14m, and the area of trapezium is 196m2, Find the length PQ.
Answers
Answer:
PQ = 11 m
Step-by-step explanation:
In trapezium PQRS,
PQ and RS are parallel lines and PT is the perpendicular distance between the parallel lines
a = PQ
b =RS = 17 m
d = PT = 14 m
[tex]\frac{(a+b)*d}{2}= 196\\\\\frac{(PQ + 17)*14}{2}=196\\\\(PQ + 17) * 7 = 196\\\\PQ + 17 = \frac{196}{7}\\\\PQ + 17 = 28\\\\PQ = 28 - 17\\\\PQ = 11[/tex]

Step-by-step explanation:
soooooo its a 90 degree angle
2x+1+33=90
2x+34=90
-34
2x=56
x=28
Answer:
x = 28°
Step-by-step explanation:
As you see that the angle is an right angle where right angles = 90°
So,
(2x + 1) + 33 = 90°
Subtract 33 on both sides:
2x + 1 = 57
Subtract 1 on both sides:
2x = 56
Divide 2 on both sides:
x = 28°

B. On average, 17% of the adults visited the park most frequently.
C. On average, 2 out of 25 adults visited the aquarium most frequently.
D.On average, 2 out of 10 adults visited the museum most frequently.
Answers
Answer:
D.
Step-by-step explanation:
In total, there are 70 people.
31/70= around 44.2%
14/70= 20%=2/10
17/70= around 24.2%
8/70= around 11.4%
Using proportions, it is found that the correct statement is given by:
D. On average, 2 out of 10 adults visited the museum most frequently.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, there is a total of 31 + 14 + 17 + 8 = 70 adults.
Applying the rule of three, 2 out of 10 considering 70 adults is equivalent to 14 adults, hence option D is correct.
