2,3,5! 1 is NOT a prime number!
Answer:
A = 441 in²
Step-by-step explanation:
An isosceles right triangle is a triangle with two equals sides (the legs ). In this particular case the base of the triangle will be the length of one side and at the same time the height of the triangle will be the other leg. Hypotenuse as always is the opposite side to the right angle.
The area of a triangle is
A = (1/2) * b* h
If we are going to compute the area of such triangle we have to find the length of one side That will be the base of the triangle and at the same time that will be the height of the triangle.
In any right triangle hypotenuse is:
H² = L₁² + L₂² (1)
As was explain before in this particular case L₁ = L₂
Then
H² = L₁² + L₁² ⇒ H² = 2 L₁² H = √2 * L₁ ⇒ L₁ = 42/√2
Then area of the
A = (1/2)* ( 42/√2) * ( 42/√2 ) ⇒ A = 1/4 * (42)²
A = 441 in²

Answer:
$1279.25
Step-by-step explanation:
The first $6800 is multiplied by .085 to get the 8.5% they earned. This equals $570. After that, the remaining money is multiplied by .1275 to get the 8.5%+4.25%. This leaves you with $5500x.1275. This equals 701.25. $701.25+$570=$1279.25. Hope this helps :)
