Hi there!
Dimensions of rectangular room :-
• Length = 109 inches
• Breadth = 103 inches
Dimensions of square tiles :-
• Each side = 3 inches
It's known :-
No. of tiles = Area of rectangular room / Area of tile
No. of tiles =

No. of tiles =

No. of tiles = 1,247
Hence,
Th' number of tiles required for the job is 1,247
~ Hope it helps!
Answer:
4(3x+2)
Step-by-step explanation:
Just factor the expression.
2y is in the first equation so if you change 0.5x+y=17 to y=17-0.5x and then double it to 2y=34-x, you can substitute and find x. And then you can find out y.
How to find x:
0.5x+y=17
y=17-0.5x
2y=34-x
3x-2y=8
3x-34-x=8
<u>x=21</u>
How to find y (with previous info.)
x=21
3x-2y=8
3*21-2y=8
63-8=2y
55=2y
<u>27.5=y</u>
Y=0.15x because you x equals the number of late days and y equals 5.70
Answer:
b = (5±√17)/4 ≈ {0.2192, 2.2808}
Step-by-step explanation:
The average on the interval is found from the integral ...

We want the value of this integral to be 5, so we want to find b such that ...
5 = -2b^2 +5b +4
2b^2 -5b +1 = 0
b^2 -5/2b = -1/2
b^2 -5/2b +25/16 = -1/2 +25/16
(b -5/4)^2 = 17/16
b = (5±√17)/4
The average value of f(x) is 5 on the intervals ...
[0, (5-√17)/4] and [0, (5+√17)/4]
