Answer:
(2,6) radius=8
Step-by-step explanation:
this is becuase the 2 is put into the (x-(centerx)) and the 6 is put into (y-(centery)). The radius is the square routed, so you get the original number of 8
Answer: 4:5
Explanation:
Steve earns 8 dollars an hour. His brother earns 10 dollars an hour.
The ratio is Steve:Brother, which is 8:10.
This can be treated the same was as a fraction and simplified, dividing both sides by 2, which becomes 4:5
Answer:
x*90= your answer.
Step-by-step explanation:
X being however many test scores there are.
If you have 4 test scores, you would multiply 4*90=360
If you had 3 test scores, you would do it again, 3*90=270.
And so on. Because the test scores number wasn't listed, I provided some answers on how to solve it.
Answer: Choice 1) The sum of the angles A and B are supplementary to angle C
Why is this the answer? Because we'll use facts 2 through 4 to help prove the triangles similar. If fact 2 is true, then fact 3 leads to helping set up the congruent corresponding angles (either A = D or C = E). Fact 4 is true because all angles are congruent to themselves, and this fact is the other angle pair we need to prove the triangles similar.
We don't use fact 1 even though it's a true statement. The fact that A+B+C = 180 isn't really useful to compare across two triangles.
Answer:
The correct answer is option 3. (20, 4, 5)
Step-by-step explanation:
To solve this problem we use the substitution method.
(i)
(ii)
(iii)
We start by clearing x in (iii) and clearing y in (ii).
(iii)
(ii)
Now we substitute (iii) in (ii)
(iv)
Now we substitute (iii) and (iv) into (i) and clear z.
(v)
If (v)
We substitute (v) in (iii) and then substitute (v) in (iv)
The correct answer is option 3.
