Answer:let 't' represent the cost of a taco and 'm' represent the cost of a glass of milk
Step-by-step explanation:2.10 = t + m
5.15 = 2t + 3m
The sum of interior angles of a triangle is 180 degrees. If we’re trying to find the triangles last angle on the right, we will subtract 180-60-50 which equals 70. The angle missing on the right side is 70 degrees. There are opposite angles in this shape so the other angle beside a would also be 70 degrees. Now we only have a left and you do the same thing with the sum of interior angles with that triangle. So you do 180-70-65 and you’re left with 45. Therefore, a is 45 degrees.
What i do know is it that its not c, or d its to high and it is a or b.
<span>A sample of n=8 has an ss=50 if these were a population the ss value of the population would be
(50/8) of the sample = 6.25 of sample. Usually, ss value of the population i s calculated by dividing ss by the sample values. This is the way to calculate ss value of the population.</span>
