15= 15/1, 4= 4/1 and 1/= 1/3 1/3 * 15/1= 5/1= 5 4/1= 4 5*4=20
The anwser is 20
$${\frac{{\mathtt{1}}}{{\mathtt{3}}}}{\mathtt{\,\times\,}}{\mathtt{15}}{\mathtt{\,\times\,}}{\mathtt{4}} = {\mathtt{20}}$$
or
$${\frac{\left({\mathtt{1}}{\mathtt{\,\times\,}}{\mathtt{15}}{\mathtt{\,\times\,}}{\mathtt{4}}\right)}{{\mathtt{3}}}} = {\mathtt{20}}$$
The altitude in an isoceles right triangle creates two congruent triangles whose base and height are each = 6.
So .... 2 (1/2) b * h = 2 (1/2) 36 = 36 sq units
thats what i said awesomeee ...
Don't worry, civonamzuk.....the wind has blown away a few of mine, too....LOL!!!
there doesnt have to be an explanation
oh... Its 32 i think... do we need an explanation? cuz im too lazy. well, the anwser is 32. 32=32 lol
plz insert an explanation formally in kid friendly language. it can be an 'only numbers and equations' explanation, thx
@CPhill:/ Yes, you are correct! You would be even more correct if I wrote down the month of our birth.
@Anonymous:/ In my case, those years are gone with the wind...
the anwser is 11. 11* 11 = 121
points
this is for points
Let y be the years between the time you were 48 and the time when you will be three times as old as your daughter ... (2021).....so we have
48 + y = 3(y + 2)
48 + y = 3y + 6
42 = 2y
y= 21
So you will be 69 in 2021.....so you're 6 years younger now = 63
Check....
Your daughter will be 23 in 2021.....so she was born in 1998
When she was 2 (in 2000), you were 15 years younger than you are now....so 63 - 15 = 48....and this was 24 times her age in 2000....!!!!
Am I correct????
Umm 32 ?
I still don't get it :/ sorry
11 is your answer.
I don't know, try exponential growth with say dogs. if 2 dogs make 2 puppies each, there will be 4 puppies. if 4 dogs make 2 puppies each, there will be 8. then 16, 32, 64, 128, 256, 512, 1024, 2048, and so on.
Radius is half the diameter of a circle. Let's say you poke a hole in the middle of a pie. Then, cut a line to the crust, or the edge. That line you made is the radius.
3(2y+3) = 5y+9 distribute the "3" across the terms in the parentheses
6y + 9 = 5y + 9 subtract 9 ftom both sides
6y = 5y subtract 5y from both sides
6y - 5y = 0 factor out y
y(6 - 5) = 0
y*1 = 0
y = 0
s = 2 [(3/4)pi ] = 3/2pi = about 4.71 in
