Answer:
1/3 is the fraction
Step-by-step explanation:
total outcomes = 3
total no. of favorable outcomes = 1
answer = 1/3
To find the area of the dining room, take 20m x 20m=400m
The area of each tile is 20cm x 20cm=40cm.
Convert the are of the dining room to cm which is 400 x 100= 40000cm
The divide the area of the dining room by the are of the tiles to find how m,any tiles are needed.
Which is 40000cm/40cm= 1000 tiles
There are 1,000,000 milliliters in one liter
To convert cm³ to m³, you can break down the units.
cm³ = cm x cm x cm
Each cm is converted to m so :
m³ = m x m x m
= 1/100 x 1/100 x 1/100
= 0.000001
So, 1cm³ is 0.000001m³, so to convert cm³ to m³ you divide your value by 1,000,000 and vice versa.
1. 0.35m³
2. 8m³
3. 43.34m³
4. 30m³
5. 0.77m³
If you are in college, this question is likely done with calculus.
a = 12
k = 0.2
v(x) = 0 at the maximum after differentiation
V(x) = kx(a - x)
The easiest way to do this is to remove the brackets.
V(x) = akx - kx^2 Substitute the constants
V(x) = 12*0.2*x - 0.2x^2
V(x)/dx = 2.4 - 0.4x = 0 at the maximum
2.4 - 0.4x = 0
0.4x = 2.4
x = 2.4/0.4
x = 6
If you don't know any calculus yet, you can do this by completing the square.
