Answer:
... an <em>isosceles triangle</em>.
Step-by-step explanation:
Triangles classified by side length fall into one of three categories:
- scalene - no sides the same length
- isosceles - two sides the same length
- equilateral - three sides the same length
The pyrite cube is, well, a cube, so it has a side length <em>s</em> such that the area of its base is
<em>s</em> ² = 5.76 cm²
which means
<em>s</em> = √(5.76 cm²) = 2.4 cm
Then its volume is
<em>s</em> ³ = 13.824 cm³
Pyrite is also known as "fool's gold" because it looks a lot like gold. So if gold has a unit price of €785/cm³, then a pyrite cube with volume 13.824 cm³ could be mistaken for a gold cube of the same volume, which would sell for a price of
(€785/cm³) × 13.824 cm³ = €10,851.80
Answer:
24
Step-by-step explanation:
X + (X + 2) = 50
2X = 50 - 2
2X = 48
X = 24
Answer:
Step-by-step explanation:
we know that
The perimeter of rectangle is equal to
In this problem we have
substitute in the formula and solve for L
simplify
<span>Step 1: find the radius
The radius is half of the diameter. So the radius is 8 because the diameter is 16.
Step 2: square the radius.
8^2 = 64
Step 3: plug into formula
pi * radius squared * height
3.14 * (64) * (1.8) = 361.728 m^3
The volume of the pool is 361. 728 meters cubed.
Step 4: Divide volume by the amount pumped out per hour
volume / amount pumped out = amount of hours
361.728/16 = 22.608 hours.
So your answer is approximately 23 hours.</span><span>
