The rectangle area is 98. So if you split it in half, you would get 2 squares. Half of 98 is 49.

If it is now a square, you now simply know, that 7*7=49. Meaning that The sides of the square are 7 each.

7 times the 4 sides equals 28. So the perimeter of one square is 28.

24(height) cm 3.5(length) cm 13(width) cm find the surface area of the prism
Kitty [74]

Answer:

2395 cm²

Step-by-step explanation:

You need to find the area of each side of the prism.

the first side is 3.5x24 which equals 840. there are two of those sides since it's a prism, so multiply by 2. 840x2=1680.

the second side is 13x3.5 which is 45.5. multiply that by 2 for the other side, 45.5x2=91.

repeat for the third side: 24x13=312. 312x2=624.

add all of the sides up to get total surface area. 624+91+1680=2395. :)

Using fermat's little theorem, find the least positive residue of $2^{1000000}$ modulo 17.
torisob [31]
Fermat's little theorem states that
a^p≡a mod p

If we divide both sides by a, then
a^{p-1}≡1 mod p
=>
a^{17-1}≡1 mod 17
a^{16}≡1 mod 17

Rewrite
a^{1000000} mod 17  as
=(a^{16})^{62500} mod 17
and apply Fermat's little theorem
=(1)^{62500} mod 17
=>
=(1) mod 17

So we conclude that
a^{1000000}≡1 mod 17
