There were 845 million facebook users at the end of 2011, wich was up from 608 million users at the end of 2010.

1 answer:

5 0

So,

All we have to do is multiply 845 million by 51.5%, or 0.515.
845 million * 0.515 = 435.175 million users

435.175 million, or 435,175,000 users accessed Facebook using mobile devices.

Please tell me this asap.. y/2 - 1/5 = 2 - y/3

musickatia [10]

Answer:

y=2 16/25

in other words, two and sixteen twenty-fifths

Step-by-step explanation:

y/2-1/5=2-y/3

Move the variables to one side and constants to the other

y/2+y/3=2+1/5

Multiply y/2 by 3/3 and y/3 by 2/2 so that they have a common denominator

3y/6+2y/6=2 1/5

5y/6=11/5

Cross multiply

66=25y

y=66/25

y=2 16/25

Evaluate the expression when: A=2, B=1, C=4 A+6/CB

vovikov84 [41]

Answer:

Imma rewrite the question as: 2+6/41

2+6=8

i think since the letters were next to each other u multiply?? Is so...:

4x1=4

8+4=12

=12

but if u add the letters next to eachother....

2+6=8

4+1=5

8+5=13

=13

or if u use “41” as a whole number and add it in..:

2+6=8

8+41=49

=49

Write the equation for a parabola with the focus at

katen-ka-za [31]

The answer is (y - 4)2 = -12(x - 2)
Since the graph is facing the left, the starting equation would be (y - k)2 = -4p(x - h).
(h, k) is the vertex of the graph. If you plot the focus and the directrix, you can see that the distance is 6. Divide 6 by 2, thus the vertex should be 3 squares away from the focus and 3 squares away from the directrix. The vertex is (2, 4). And since the distance from the focus to the vertex and the distance from the directrix to the vertex is 3, P = 3.
Insert the numbers in and you should get the last choice.

During the national day celebrations.Asha decorates her balcony with serial lights of red,green and white colours.The red light

expeople1 [14]

If all three coloured lights blink together at 8:49 pm, they will blink together at 8:50 pm

Solution:

Given that the red light blinks at intervals of 4 seconds, the green at 5 seconds and the white at 6 seconds.

If all three colored lights blink together at 8:49 pm,

We have to find when will they blink together again?

First let us know, at what intervals they all together blink.

For that we have to find the lcm of 4, 5, 6.

L.C.M (4, 5, 6) = 2 x L.C.M(2, 5, 3)

As 2,3,5 are primes, we can’t take common further, so multiply all

= 2 x 2 x 5 x 3

= 4 x 15 = 60

So, after every 60 seconds = 1 minute they will blink.

Then, after 8 : 49 pm, they will blink at 8 : 49 + 1 = 8 : 50 pm.

Hence, they all blink at 8 : 50 pm.
