b and d
Answer:
D
Step-by-step explanation:
128/2 = 64
The squareroot of 64 = 8
That means that only C or D could be true; 8 is in the numerator not the denominator.
Look at the ys next. There are 5 in the denominator and 6 in the numerator. Five of them will cancel out leaving 1 in the numerator. That makes D the answer. However we should check out the xs.
There are 5 in the numerator and 7 in the denominator. That means that there are 2 left in the denominator. Since the xs are squared in the denominator, to remove the square root sign, you need to take out 1 x from under the root sign and throw the other one away.
Answer 8sqrt(y)/x
D
Answer:
-28r - 28
Step-by-step explanation:
-4 * 7 = -28.
Therefore, -28r - 28 is the new equation. It can' be simplified any further
The rules are very simple: an angle is acute if it's less than 90°, whereas it is obtuse if it's more than 90°.
So, for the first task, you just need to compare the given angle with 90°. If the angle is less than 90°, it's acute. Otherwise, it's obtuse.
Moving on, angle B is complement of a angle A if A+B=90. So, for example, the complement of the first angle is 80, because 10+80=90. Note that this implies that obtuse angles don't have a complement.
Finally, angle B is supplement of a angle A if A+B=180. So, for example, the complement of the first angle is 170, because 10+170=180.
Answer:
_
-0.416 or for rounded 0.417
Step-by-step explanation:
when you multiply -1/4 and 5/3 you will get a repeating decimal so what you will do is ether round it or put a line on top of the 6 showing that the number six never ends so when you round it you should round the thousandths plae making it -0.417
