<span>length is 3 times the width = 3W
A = L * W
48 = 3W * W
48 = 3W^2
W^2 = 48/3
W^2 = 16
W^2 =4^2
W =4
answer: width is 4ft</span>
Answer:
45 I think is the answer it's my guess
Here's what you have to keep saying to yourself until it carves a new
groove into your brain and you don't have to think about it any more:
<em> " log(x) = the power that 10 must be raised to </em>
<em> in order to wind up with 'x'. "</em>
You said 2.36 = -log(x)
Multiply each side by -1 : log(x) = -2.36
Now translate it into the mantra:
<em> The power that 10 must be raised to </em>
<em> in order to wind up with 'x' is -2.36 .</em>
Do you see what that means ? ! ?
If the power that 10 must be raised to in order to wind up with 'x'
is -2.36, then all you have to do to find 'x' is raise 10 to the power
of -2.36 ! You can do that with about 4 clicks on your calculator.
10^(-2.36) = <em>0.004365...</em> (rounded)
And if you don't quite believe it, it's even easier to check it.
Punch " 0.004365 " into your calculator, and then touch the
" 10^x " key, and something very close to -2.36 will pop up
right there, before your wondrous eyes.
Since the two angles form a linear pair, the sum of their
angles is equal to 180°. The condition given in the problem is that one angle is
one-third of the other angle, or simply speaking, one angle is three times more
than the other angle. We find the values of the angles by dividing the sum of
the angles by 4 and assigning 3 and 1 times the dividend.
180°/4 = 45°
By obtaining the dividend, we obtain the values of the
angles to be 45° and 135°.
4.74/.06=79
19.44/.54=36
I used a calculator. You can change each decimal into a fraction to solve too.
