Tyrell katy and lucy were eating grapes. Tyrell ate twice as many grape as katy, and lucy ate half as many grapes as katy. If katy ate 6 grapes how many grapes did the three of them eat in all?

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.

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)
