Answer:
36 inches
Step-by-step explanation:
Let's draw a parallelogram real quick:
W _____________________ X
/ /
Y /____________________/ Z
So, we know that WY and ZX are the short sides and that they both equal 12. We also know that YZ and WX are the long sides and are 3x longer.
12*3 is 36 inches.
A 90º degree angle is a right angle. Anything below is an acute angle and anything more than 90º is an obtuse angle.
12.6 lb = 100.8 oz.Because you need to show your work, on the side put the expression 12.6 * 8 = 100.8 but replace the * with the times sign.
I would start by converting everything into decimal, as it makes it a LOT easier to understand.
So, you should be able use a calculator to convert the square roots and fractions into decimal. Let's start.
Square root 12 is equivalent to 3.46 (to 2 decimal places)
Square root 9 is 3 (you should know that because 3 × 3 = 9)
12 is already in decimal so it's just 12
3.56, 4.03 and 4.2 are also in decimal so you leave them
Square root 17 is 4.12 (to 2 decimal places)
Square root 2 is 1.41 (also 2 decimal places)
1/2 is the same as 0.5 (once again, you should know that)
And 3/2 is the same as 3 ÷ 2, which is 1.5.
So in order of least to greatest, it's:
1/2, square root of 2, 3/2, square root of 9, square root of 12, 3.56, 4.03, square root of 17. 4.2 and finally 12.
Hope this helps :)
