Answer:
tan(45°) = 1
Step-by-step explanation:
We know that sin (45°) = √2/2, and cos(45°) = √2/2.
Given that tan(x) = sen(x) / cos(x), we get:
tan(45°) = (√2/2) / (√2/2) = 1
Therefore, tan(45°) = 1

Answer:
Step-by-step explanation:
It sounds like you are asked to estimate it. That's a very valuable skill.
9.634 is about 10
445.76 is about 446
So an approximate answer is 446 * 10 = 4460
How close is that to the actual answer? Let's find out.4294.45
On a test, if you get an answer like 4460 in your head, and your calculator says 4294.45, you are pretty certain that you have done the question correctly.
The answer is 112.4 because 24.5+24.5+31.7+31.7=112.4.
The 13.5 fl. oz bottle is better, because it is cheaper per ounce.
The 16 fl. oz bottle is $6.19, so it is $6.19/16oz = $0.38/oz
The 13.5fl. oz bottle is $3.99, so it is $3.99/13.5oz = $0.29/oz
0.29 is less than 0.38, thus the 13.5 oz is cheaper and the better buy.
