Answer:
It would be 6 dollars
Step-by-step explanation:
20 percent of 30 dollars is 6 dollars.
If an item costs 30 dollars and it's on sale for 20 percent off, how much will you save? To figure this out, you need to find 20 percent of 30.
This is easy to do in your head. Think of what 10 percent would be. 10 percent of 30 would be the same as .10 x 30, or 3. So, 10 percent off is 3 dollars off.
20 percent is twice as much as 10 percent. If 10 percent off is 3 dollars, then 20 percent off would be 2 x 3 or 6.
20 percent of 30 dollars would be 6 dollars.
Answer: I think the answer maybe 12
Step-by-step explanation:
4 x 6 ÷ 2 = 12
Therefore, 2.52 ÷ 50.8 ≈ 0.0496.
0.049600...
=0496
Answer:
Step-by-step explanation:
We can easily determine the exact value of this unknown angle by breaking it into known angles that can add together to give up 105. For example, 105 degrees is 60 + 45, both of which are found on the unit circle. We ill also use the trig identity for the sum of the cos of 2 angles which is:
These values are found on the units circle, so make sure you have one handy. Those values fill in as follows:
which simplifies to
Maybe. if a mxn matrix is multiplied by a nxp matrix, you can and will get a mxp matrix result.
