Find the total area of the room
109 * 103 = <span>11227 inches^2
the tile takes up 3*3 = 9 inches^2
11227/9 = </span><span>1247.4
You need 1247 tiles and 0.4 of a tile.
Or you could just get 1248 and cut the last tile a bit :P
Hope this helps :)</span>
Step-by-step explanation:
c = 8 × 4.2 (move 8 from the denominator to the side where the 4.2 is - make c the subject)
c = 33.6
Answer:
63 degrees.
Step-by-step explanation:
TRaingle ABC is isosceles so the base angles are equal That is < BAC = < BCA.
<BAC = 180 - 117 = 63 degrees ( because it is adjacent to <x which is 63 degrees).
So < BCA = <BAC = 63 degrees.
Finally y = 63 degrees ( vertical angles are equal).
We can solve for the surface area of the triangular prism using the formula below:
SA=bh + (s1+s2+s3) H
where b for the base, h and H for the height while s1, s2 and s3 for the length of the sides of the equilateral triangles.
Solution is shown below:
SA=10*9+(10*10*10) *18
SA=90+(1000*18)
SA=1,620,000 u²
Hey You!
The GCF of 24 and 60 is 12.
We can divide 24 and 60 by 12, so the simplest form would be: 2/5
