14.25
Step-by-step explanation:
95 x 0.85 = 80.75
95-80.75 = 14.25
The answer is 16/9. does this help?
That mean like: Multipication, Division, Addition, Subtraction stuff like that.
Part One
The cost of 2 liters is $2.40
The cost of 1 liter = 2.40/2 = 1.20
Part two
1 bottle contains 12 liters
6 bottles contain 12*6 = 72 liters.
All of this comes at a cost of 3.90
The cost is 3.90 / 72 = 0.054 dollars / Liter which is about 5 pennies.
The one with the higher cost is 1.40 dollars / liter. Part One. Answer
By Pythagoreans' theorem,
7.5² = l² × b²
56.25 = l² × b²
Since l = b
56.25 ÷ 2
= l²/b²
= 28.125 mm
∴ l = √28.125
= 5.3033 mm
Area of square
= √28.125 × √28.125
= 28.125 mm²
≈ 28.1 mm² (3s.f.)
