Answer:
Step-by-step explanation:
Area = L * W
L = 1/2
Area = 5/16
5/16 = 1/2 * w You could do this using decimals
5/16 = 0.3125
1/2 = 0.5
0.3125 = 0.5 * w
w = 0.3125/0.5
w = 0.625
w = 5/8
The other way is done by fractions
There are a couple of notes
- First, you invert and multiply the denominator (the bottom fraction). It becomes 2/1
- Second the 2 and 16 cancel 5/16 becomes 5/8
We let x = Leslie's age
y = Bill's age
A. What expression represents Leslie's current age?
x = 8 + y
B. What expression represents bills age in 4 years. What expression represents Leslie's age in 4 years?
x+4 = 2(y+4)
C. What equation can you write based on the above given information?
You can have 2 linear equations with 2 unknowns.
D. What's bills current age? What is Leslie's current age?
x = 12 ----> LESLIE
y = 4 -----> BILL
The point (8,2,9) is in the first octant.
The closest distance from the coordinate planes is the value y=2, which will therefore be the maximum radius of the required sphere.
The standard equation of a sphere with radius r and centre (u,v,w) is given by
(x-u)^2+(y-v)^2+(z-w)^2=r^2
Substituting r=2, u=8, v=2, w=9, we get the equation of the required sphere
(x-8)^2+(y-2)^2+(w-9)^2=2^2
