Answer:
A. 30 two-point questions and 10 four-point questions
Step-by-step explanation:
30 multiplied by 2 equals 60
10 multiplied by 4 equals 40
60 plus 40 equals 100 points which is the amount of points the test is worth as stated i the question.
30 plus 10 equals 40, which is the total amount of questions in the test as stated in the question.
5d=470:
in this case we have to divide both sides by 5:
d=94
8a=47:
in this case we have to divide both sides by 8:
a=5.875
as a general rule, if you want to find out a value of a in
ab=c
you have to divide both sides of the equation by b (if it's not zero); then you will have left:
a=c/b
and if you calculate c/b, this will give you the answer
Answer:
30
Step-by-step explanation:
Each z-score = 1 standard deviation from the mean, so 18 + (6 x 2) = 30
Answer:
147°
Step-by-step explanation:
The measure of arc CH is equal to the central angle it sees
the angles arc AH sees are BAC and CAH so the length of arc AH would be the sum of these two angles
90° + 57° = 147°
Answer:
ASA
Step-by-step explanation:
We can see that the triangle has at least one similar side and one similar angle. We can also see that the triangles meet at a point, so they must have the same angle at that point where they connect. So that leads us to our answer being ASA since they have two similar angles and one similar side. This is the answer that I think is correct just by looking at the image. I haven't take this class since last year, so this is simply from memory. Correct me if I am wrong!
