Answer:
0 / 4 = 0, this is true
Step-by-step explanation:
4 / 0 is not defined.
so you first at the two numbers then you at the number to go out with a second then you keep doing that until you get into you don't have no more to answer so thank you
81^2 = 18 ^2 + 80^
6561 = 324 + 6400
6561 = 6724
<span>It is not a right angle, since 18^2 + 80^2 does not equal 81^2.
So,
Using </span><span>The law of cosines:
</span>The largest angle C is opposite to the side c.
Therefore,
<span>c^2 = a^2 + b^2 -2ab cosC </span>
<span>Here,
c^2 < (a^2 + b^2)
cosC must be positive which makes C an acute angle.</span>
Answer:
21 grapes.
Step-by-step explanation:
We have been given that Tyrell ate twice as many grape as Katy. Lucy ate half as many grapes as Katy. Katy ate 6 grapes. We are asked to find the total number of grapes that all of them eat in all.
First of all, we will find twice of 6 grapes to find number of grapes eaten by Tyrell.
Now, we will find half of 6 to find number of grapes eaten by Lucy.
Therefore, the three of them eat 21 grapes in all.
