Answer: Yes that I correct.
Step-by-step explanation:
Because 25 times 4 is 100 and what you do to the bottom you have to do to the top so 7 times 4 is 28
Answer:
625
Step-by-step explanation:
5x5
25x5
125x5
625
Square root 62.8. Which will give you 7.9.
7.9 divided by pi times 5.
7.9 divided by 15.7.
The radius would be 1.9 if left as a decimal, but rounded to the whole number would be 2.
Hope this helps and answers your problem!!!
We calculate the floor area of the kitchen:
A = (22) * (16)
A = 352 feet ^ 2
We consider the following conversion:
1 foot = 12 inches.
Applying the conversion we have:
A = 352 * (12/1) ^ 2
A = 50688 in ^ 2
We calculate the area of each tile:
A = (16) * (16)
A = 256 in ^ 2
Then, the number of tiles is given by:
N = (50688) / (256)
N = 198
Answer:
He needs to buy 198 tiles
(x+1)(x-4)-(x-2) = 0
x²-4x+x-4-x+2 = 0
x²-4x-2 = 0
/\ = (-4)² - 4*1*(-2)
/\ = 16 + 8
/\ = 24
x = (-(-4)+/- \/24) / 2
x = (4+/-\/4*6)/2
x = (4+/-2\/6)/2
x = 2+/-\/6
x' = 2+\/6
x" = 2-\/6
