Answer:
4 hours
Step-by-step explanation:
In 6 hours, J paints 1 room
So, in 1 hour, J paints 1/6 th of the room
Using similar logic, in 1 hour, T paints 1/12 th of the room.
Working together in one hour, they paint (1/6+1/12) th =1/4 of the room.
1/4 of the room is painted in 1 hour
So, 1 room is painted in 1 1/4=4 hours
Answer:
9x sqrt 5x
Step-by-step explanation:
Simplify the radical by breaking the radicand up into a product of known factors.
9x√
5x
Step-by-step explanation:
as the denominator (x+3) is in both you need only one denominator to be multiplied in first rational number .
<u>2</u><u>x</u><u> </u><u>(</u><u>x-2</u><u>)</u><u>. </u><u> </u><u> </u>+ <u>5</u><u>. </u><u> </u><u> </u><u> </u><u> </u><u> </u>
(x+3) (x-2). (x+3) (x-2)
<u>2</u><u>x</u><u>^</u><u>2</u><u>-</u><u>4</u><u>x</u><u> </u><u>+</u><u>5</u><u> </u>
<u>(</u>x+3) (x-2)
it's cannot be solved after that.
Answer:
1.17 Euros
Step-by-step explanation:
Given that £1 equals 1.25 dollars then to get the value of 1 dollar will be 1/1.25=£0.8
If 1 Euro equals to 1.07 dollars and knowing that 1 dollar is equal to £0.8 then 1.07 dollars will be equal to 1.07*0.8=£0.856
1.07 dollars=£0.856=1Euro
1.25 dollars =£1=x Euros
Cross multiplying the last two parts then
£0.856* x Euros=£1*1Euro
X=1/0.856=1.1682242990654
Rounding off to 2 decimal places, x=1.17
Therefore £1 is worth 1.17 Euros
Answer:
<em>=84</em>
Step-by-step explanation:
If we have n types of elements and we have to choose r elements from then, then we have C(n+r-1, r) r-combinations.
To choose 6 different candles,
n=4(4 types of candles), r=6(no of candles to pick)
=C(4+6-1,6)
=C(9,6)
= 9! / (9-6)! (6!)
= 9!/ 6! 3!
=84
