Surface area is much easier then area in this case.

You would just find the area of each side, and since you know the slant height, if you were to take each side of the pyramid as a 2D figure, the base would be 6.4 inches as stated and the height 6.1, because if you look at where the slant height is and basically took a side as a 2D figure, it would be the same as the height.

Pretty sure most people know how to find the area of a triangle, but it's base * height / 2, or 6.4 * 6.1 / 2, or 19.52. Since there are four of these triangle side things, just multiply 19.52 by 4, to get 78.08.

There's still a square base, so just multiply 6.4 by itself to get 40.96.

Now just add the two together to get 119.04.

3x + fraction 1 over 4 y^2 what is the value expression above when x=3 and y=4? Must show all work and calculations
evablogger [386]

Answer: 9 1/16

nine and one sixteenth

Step-by-step explanation:

Substitute x = 3 and y = 4 into the equation:

3x + 1/4^y

= 3(3) + 1/4^(2)

Then solve using the order BEDMAS (brackets, exponenets, division, multiplication, addition, subtraction).

= 3(3) + 1/4^(2)

= 3(3) + 1/16

= 9 + 1/16

= 9 1/16

An 8-car Ferris wheel is shaped like a regular octagon. Does the Ferris wheel have rotational symmetry?
sleet_krkn [62]

Answer:

Yes, it does.

Step-by-step explanation:

Every regular shaped figure will have rotational symmetry, since they are built with identical segments all around.

To find the answer, ask yourself « If I rotate the shape, is there a time where I’ll find the exact same shape again with a different angle? »

So, a square has rotational symmetry, but not a rectangle.

A equilateral triangle has rotational symmetry, but not any other type of triangle.

Stephanie can type around 70 words per minute. She has less than a week to type her final research paper. If the paper has to be
Lana71 [14]
The answer is 1.25 hours.

STEP 1.
Each page has about 350 words:    1 page - 350 words
15 pages is x words:                         15 pages - x words
1 : 350 = 15 : x
x = 15 * 350 : 1 = 5250

So, she has to type at least 5250 words.

STEP 2:
<span>Stephanie can type around 70 words per minute:     70 words - 1 minute
x words in 1 hour = 60 minute:                                        x words - 60 minute

70 : 1 = x : 60
x = 70 * 60 : 1 = 4200

So, she types around 4200 words per hour.


STEP 3:
Now we have:
</span>- she has to type at least 5250 words
- she types around 4200 words per hour

5250 : x = 4200 : 1
x = 5250 * 1 : 4200 = 1.25 hours

CAN U HELP ASAP ILL GIVE 15 POINTS AND PROLLY BRAINLIEST IT
gogolik [260]

Answer:

(2, 8)  and (3, 11)    --- > For example

Step-by-step explanation:

Plug in any number for x

I will use 2.

So if the equation is y = 3x + 2, then the new equation will be ...

y = 3(2) + 2

y = 6 + 2

y = 8     ----> One coordinate can be (2, 8)

Another number you could use is 3.

y = 3(3) + 2

y = 9 + 2

y = 11    ----> Another coordinate may be (3, 11)
