We know that 172 of them were wood, so the rest are metal. To find that number we do:
276 - 172 = 104 metal pins.
To find the percentage that they were metal, take the number of metal pins and divide by the total number of pins:
104/276 is about 0.3768.
Multiply this by 100:
37.68
So, the percent of metal pins is 37.68%.
Answer:
y = x + 15
Step-by-step explanation:
You swim 15 minutes more than a friend.The friend swims x minutes.
The amount of time you swim is 15 more than x.
Your time is y
Therefore y = x + 15 would be the equation.
Answer:
Step-by-step explanation:
y = -8x - 49
y = -x
- -8x - 49 = -x
- -8x + x = 49
- -7x = 49
- x = -7
- y = - (-7) = 7
Answer:
38 degrees
Step-by-step explanation:
It is 38 degrees because if you add up A & B, you get 142 degrees. And 180 degrees - 142 dgrees is 38 degrees. This is how I solved it
Answer:
could be wrong so if AC=12
and B is in-between the B is a half of Ac
which is 6
