145+67=212 One other way to solve it is to solve it is you subtract.
Answer:
4 blocks of cream cheese
Step-by-step explanation:
there are 16 Ounces in a pound.
You have 4 ounces of cream cheese. 4 is 25% of 16 so we subtract .25 from the required amount which is 2.25.
NOW we need 2 pounds. well, each block is 8 ounces, and we need in total 32 ounces. 32/8=4 blocks
The answer to this question -9
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
Answer:
150,000
Step-by-step explanation:
1 m = 100 cm
260 m = 260 * 100 cm = 26000 cm
15 m = 15 * 100 cm = 1500 cm
area of floor = LW = 26000 cm * 1500 cm = 39,000,000 cm^2
area of 1 tile = 26 cm + 10 cm = 260 cm^2
number of tiles needed = 39,000,000/260 = 150,000
Answer: 150,000 tiles
