M=0 because thats the only thing you can times 5 by and get 1<4

Answer:
200 ft²
Step-by-step explanation:
Each face is an isosceles right triangle with a hypotenuse of length 10 ft. The area of each of those triangles is
A = 1/4·h² . . . . where the h in this formula is the hypotenuse length
So, the area of the four faces (the lateral area of the pyramid is 4 times this, or ...
A = 4·1/4·(10 ft)² = 100 ft²
Of course, the base area is simply the area of the square base, the square of its side length:
A = (10 ft)² = 100 ft²
So, the total area is the sum of the lateral area and the base area:
total area = 100 ft² +100 ft² = 200 ft²

If you think about this for a little bit, you will realize the pyramid must have zero height. That is, the slant height of a face is exactly the same as the distance from the center of an edge to the center of the base. "Not drawn to scale" is a good description.
This problem is resolved with the Pythagorean Theoreme.
It states that the length of the side that is the hypotenuse (the side opposite the right angle) is equal to the square root of the sum of the length of the other two sides squared.
So we know that the ground and the building form the right angle, so the hypotenuse is the length of the ladder (L) and the building (B) and the ground (G) are the other sides of the triangle (legs). So by the pythagorean theoreme:
L = √ (G^2+B^2)
As we already know the length of the hypotenuse, we have to isolate the variable that we don’t know (B).
B = √(H^2-G^2)
Replacing:
B = √(7^2-2^2)
B= √(49-4)
B = √45
B = 6,7 feet
I hope you find my answer helpful.
Answer:
Assuming you mean 2+ (4/5), no
Step-by-step explanation:
=2* (5/5) + (4/5)
=10/5 + 4/5
=14/5
if you mean (2+4)/5,
its 6/5, so still not 1/3
