In the first image, notice that the figure is a cube
also known as a "square prism."
Since a cube is composed of square bases, we
want to find a net that is composed of all squares.
Notice that the option of the bottom left is composed of squares.
So this net matches the figure.
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.
So what is the rest of the question
Answer:
- <u>200,000</u><em> 6-digit numbers can be constructed.</em>
Explanation:
Since the number is greater than 600,000, the first digit must be 6, 7, 8, or 9, so 4 different options: 4
The second, third, fourth, and fith digits can be either number 0 through 9, so 10 options for each one: 10 × 10 × 10 × 10.
Since the number must be odd and greater than 600,00, the last digit is odd, so it can be 1, 3, 5, 7, or 9, so 5 different options: 5.
Using the multiplication counting principle, you muliply the independent options to obtain the number of different combinations:
- 4 × 10 × 10 × 10 × 10 × 5 = 200,000.
Qualitative has to do more with your senses, and quantitative is more about numbers. Quantitative would be something like the volume is 25.5 mL, but the liquid being blue would be qualitative since it has no numbers
