Perimeter is adding all 4 sides together.
So there are 2 sides that are 6.5
So then, 2(6.5) = 13
34 - 13 = 21
21 / 2 = 10.5
Height = 10.5 units
The answer would be .4% of the 150 would be boys choosing this. Here's my work.
First, I found out what 3/5 of 150 would be (divided by 5, then multiplied by 3)
Then I subtracted that number from 150 and ended up with 60 (since 3/5 of 150 is 90)
And finally, I took 60 and divided that by 150 to get .4% of the 150 students who said their fav flavor of ice cream was chocolate was boys.
Rounding to the nearest hundredth would equal a more accurate and precise answer since more decimals are present. Your answer would be even more accurate if you rounded to the nearest thousandth.
