The right triangle is also Isosceles. It has two equal angles of 45°.
(hypotenuse)² = 2S²
4 = 2S² => S = √2
Therefore B is the correct answer.
In order to combine fractions, they need to have the same denominator.
To figure out what value to make the denominator, find the least common denominator of 4 and 5:
4: 4, 8, 12, 16, <u>20</u>
5: 5, 10, 15, <u>20</u>
<u />
The LCD is 20, so multiply 4/5 by 4/4 and -1/4 by 5/5 to make the denominator = 20
Now combine the fractions
B) 9.3
9 is already a whole number. 1 divided by 3 is .33 repeated, which rounds to .3.
9.0 + 0.3 = 9.3
<span>I got two answers is that okay? The question said to select each correct answer implying that there could be more than one.
inches per year - this could make sense as well because you could easily measure the number of inches a tree grew in a year.
millimeters per week- I suppose this makes sense how fast the specific tree grew. So, if you are alllowed to pick two answers I think you could make a strong case to your teacher that this unit has the potential to be logical rate unit for tree growth.
milliliters per minute - NO. I think that this would be an illogical rate unit to use for trees because their growth is so slow that it wouldn't change by a measurable amount in just a minuet.
miles per hour - NO. Trees do not grow fast enough for this to be a logical unit rate to use. </span>
