Answer:
C: 23 cm
Step-by-step explanation:
This is the answer because:
1) Area of trapezoid is: (base1 + base2)/2 x height
2) In this case, it is 14 + 8 which is 22. 22/2 is 11.
3) Now we have to do 253/11 which is 23 cm.

Answer:
5 times as many should be your answer.
They are both equal. 96/12=8
And 8x12=96.
Hope that helped!
Answer:
3:4
Step-by-step explanation:
This is basically asking you to simplify the values and find the lowest ratio that compares their sizes. Starting with 27:36, you simplify. You could divide by 3, but 9 also works. Dividing both by 9 gives you 3:4, which is the most simplified answer.
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%.
