Which is a true statement about an isosceles right triangle?
AnnyKZ [126]

Let l be the length of a leg. Using the pythagorean theorem, the hypotenuse is

h = \sqrt{l^2+l^2}=\sqrt{2l^2}=l\sqrt{2}

So, the hypotenuse is \sqrt{2} times as long as either leg.

Sophie [7]

Given :

Emily sells erasers for $2 per package and pencils for $5 per package. she sells 220 total packages and earns $695.

To Find :

The number of packages of erasers and pencils that were sold .

Solution :

Let, number of erasers are x and pencils are y.

So, x + y = 220    ....1

Also, 2x + 5y = 695   ....2

Solving equation 1 and 2, we get :

2(220-y)+5y = 695\\\\440 - 2y + 5y = 695\\\\3y = 255\\\\y=85

x = 220 - 85 = 135

Therefore, the number of packages of erasers and pencils that were sold are 135 and 85 respectively.

Hence, this is the required solution.
