Add the three strips of cut wood together:


John will need to cut a total of 50.05cm of wood.
Subtract this total from the strip John has:

The leftover piece will be 21.95cm long.
Answer:
x^2+y^2+z^2-10x-6y-10z +50 =0
Step-by-step explanation:
Given that a sphere is contained in the first octant
Centre of the sphere is given as (5,3,5)
Since this is contained only in the first octant radius should be at most sufficient to touch any one of the three coordinate planes
When it touches we can get the maximum sphere
We find that y coordinate is the minimum of 3 thus radius can be atmost 3 so that then only it can touch y =0 plane i.e. zx plane without crossing to go to the other octants.
Hence radius =3
Equation of the sphere would be

Answer:
3:7
Step-by-step explanation:
Simplify:
12:28
6:14
3:7
The answer is B, 1.625. If you need an explanation just ask!
Let no of blueberries be x
2 x bluberries = total raspberries
So raspberries = 2x
Cherries= 4 x raspberries so
Cherries = 8 x
Grapes = 3x cherries so
Grapes = 24x
Total fruit is equal to
X+2x+24x+8x=280
35x=280
Therefore X= 280/35=8
No of cherries in the salad
=8x
=8(8)
=64 cherries in total
Hope this helped and sorry I used shortcuts
Hope u understand
