Answer:
11.35 g/mL
Step-by-step explanation:
D = m/v
D = 567.5 g ÷ 50.0 mL (I assume its measured in mL)
D = 11.35 g/mL
That's the isosceles right triangle, one of the two cliche triangles students are expected to learn. The sides of the 45°/45°/90° triangle are in the ratio 1:1:√2.
So v= 3√2 (the two legs are equal) and hypotenuse u = √2 × v = 6.

Answer:
Unit cost: $2.50 per potato
Step-by-step explanation:
Set up a proportion:
<h2><u>5 potatoes</u> = <u>x potatoes</u></h2><h2>2 dollars 1 dollar</h2><h2 />
cross multiply:
2x = 5
divide by 2 on both sides
x= 5/2 or 2.5
1. 2^2=4
Sqrt(2) ≈1.4
4+1.4=5.4
2. -2^2 = -4
Sqrt(-2) = -1.4 i -> 1
3. 3x + 2 = 14
3x=12
X= 4
