Whats the surface area of this prism plz help.Urgent

Answers

Answer 1

Answer:

Answer:

The surface area of a solid object is a measure of the total area that the surface of the object occupies. The mathematical definition of surface area in the presence of curved surfaces is considerably more involved than the definition of arc length of one-dimensional curves, or of the surface area for polyhedra (i.e., objects with flat polygonal faces), for which the surface area is the sum of the areas of its faces. Smooth surfaces, such as a sphere, are assigned surface area using their representation as parametric surfaces. This definition of surface area is based on methods of infinitesimal calculus and involves partial derivatives and double integration.

Answer:

276°

Step-by-step explanation:

In the figure attached, circle D is shown.

arc BA + arc AC + arc CB = 360°

(7n + 12) + (13n - 16) + 6n = 360

26n - 4 = 360

n = (360 + 4)/26 = 14°

arc BAC = arc BA + arc AC

arc BAC = (7n + 12) + (13n - 16)

arc BAC = 20n - 4

arc BAC = 20(14) - 4 = 276°

Answer:

The answer is 276 degrees. I checked on Khan Academy. The reason 84 degrees is NOT the answer is because that would be the minor arc, not the major arc.

Compute the standard deviation for the set of data.

Answers

Answer:

Step-by-step explanation:

First work out the mean:

Mean = (2 + 5 + 6 + 8 + 14) / 5

= 35/5 = 7.

Now subtract the mean form each of the values:

2 - 7 = -5

5 - 7 = -2

6 - 7 = -1

8 - 7 = 1

7 - 14 = -7.

The squares of these are 25, 4, 1, 1, 49

Their sum = 25 + 4 + 1 + 1 + 49 = 80

Now divide this by 5 = 16.

Standard deviation is √16 = 4.

Tickets to the museum cost $18 for adults and $12 for children. A group of 20 people went to the museum, and the tickets cost $324. The system of equations models this situation, where x is the number of adults and y is the number of children.x-y=20
18x+12y=324

How many adults and how many children were in the group?

A.
8 adults and 12 children

B.
10 adults and 10 children

C.
12 adults and 8 children

D.
14 adults and 6 children

Answers

As far as i can see, there is something wrong with one of the equationsthat are given in the question. It is mentioned in the question that atotal of 20 people went to the museum. That means that among those 20people there were children as well as adults. So the equation that ismentioned in the question given below is wrong.
x - y = 20
The correct equation would be x + y = 20
The second equation given in the question is absolutely correct.
18x + 12y = 324
Diving both sides by 6 we get
3x + 2y = 54
Now let us get back to the first equation
x + y = 20
x = 20 - y
Putting the value of x in the second equation we get
3x + 2y = 54
3(20 - y) + 2y = 54
60 - 3y + 2y = 54
60 - y = 54
-y = 54 - 60
-y = -6
y = 6
Then we get that the number of children going to the museum is 6
So
The number of adults = 20 - 6
= 14
So the total number of adults going to the museum is 14 and the number of children going to the museum is 6. The correct option in the question is option "D".
