Answer:
Step-by-step explanation:
16 rotations
500/32 = 15.625
15.625 rounded = 16
Therefore, the answer is 16 rotations.
Why:
500 and 32 are both given to you in distance. By divided 500 by 32 will give you how many times the shorter distance can fit into the longer distance. This will then give you the amount of rotations in the greater distance.
Once you have the answer, it asks for you to round to the nearest rotation. 15.625 rounds to 16 because 6 is in the tenths place. And we all know a number 5 or greater rounds up. So, 16 is the correct answer.
So the equation is (base *height)/2
In this case: 12*17= 204
204/2=102 in^3
I hope I lead you to the right path. Im sorry if I am wrong.
Hello!
To solve this, first assume all the coins are $1. Then, find the value that would have. 1 * 21 = $21.
Now, see how far away from $30 we are. 30 - 21 = 9. Therefore, we need an increase by $9.
For each coin changed from a $1 to a $2, how much of an increase is there? $1. Therefore, change 9 coins to $2 coins to have an increase of $9. If he has 9 $2 coins, he'll have 21 - 9 $1 coins, or 12.
Therefore, your final answer is 12 $1 coins and 9 $2 coins.
Hope this helps!
