2.828 because 2.8 is tenths, 2.82 is hundredths, therefore 2.828 is the thousandth. And the next number is 4 which is less than 5 so we do not round up.
4.5 is the answer for you problem
Answer:
Missing angle = 76 degrees
Informal Argument found below
Step-by-step explanation:
In order to find the missing angle, we would need to add up all of the known angles and subtract them from 180. This is because in every triangle, the angles add up to 180.
Work:
180 = 79 + 25 + x
180 = 104 + x
x = 76
Informal Argument:
The missing angle of the triangle is equal to 76 degrees. This is because all of the angles in a triangle always add up to 180 degrees. When combined with the other two angles, the triangle has a total angle measurement of 180 degrees. Therefore, the missing angle is equal to 76 degrees.
1/5(100x - 105y + 70) = 20x -21y + 14
Hello! There are a few things that determine whether or not something is a function. In this case, to determine whether a relation is a function, we look at the domains, which are the x-coordinates, the first number of the pair. If the number occurs in the x-coordinate for more than one pair in a relation, then it's not a function. If a number only occurs as an x-coordinate once in the relation, then it's a function. In other words, they each have only one y-coordinate in the relation. For this question, the first, second, and third relations are functions. The fourth one is not a function, because the 3 has more than one y-coordinate, so it occurs as an x-coordinate more than once. Here are the answers easier to read.
1st : yes
2nd: yes
3rd: yes
4th: no
