Answer:
Step-by-step explanation:
1. x = y-4
0 = y - 4 -x
4 = y - x
2. 2x+4y = 10
x+4y = 5
x+y = 5/4
The rate of change for the graph would be the last option, 35. If you follow rise over run, you end up with a rise of 35 and a run of 1, or 35/1 which simplifies to 35.
Answer:
Area of square pyramid is
.
Step-by-step explanation:
Diagram of the given scenario is shown below,
Given that,
The Great Pyramid in Giza, Egypt is a square pyramid. The area of base shape is made up with square is
. The side of the square is
and The height of each triangle is
.
So, Area of Square shape = 
Side of square = 
Height of each triangle = 
Finding the Height of triangular shape which is here known as slant height.
In Δ ABO, applying Right angle pythagorean Theorem,
Base
= 
Height
= 
Now,
∴ 
⇒ 
⇒ 
⇒ 
⇒ 
Then,
Area of square pyramid = 
=
= 
= 
= 
Hence, Area of square pyramid is
.
Hi there!
The correct answer is C) The administrator's calculation is not reasonable because my estimate of 500 is not close to 408. Let's use rounding to find our estimate. 423 is close to 400 and 931 is close to 900. If we subtract 400 from 900, we know that there was approximately 500 adults. Since 408 is not near 500, the administrator's calculation is not reasonable. In fact, they were 100 off from the correct calculation, also making it not reasonable.
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
