Answer:
18
Step-by-step explanation:
90 % 5 = 18 so A would measure 90º
Answer:
infinitely many
Step-by-step explanation:
Rewrite these equations as
y = (1/2)x + 1
2y = x + 2
and then solve the second for y: y = (1/2)x + 1. Note that these end results are identical. The two lines coincide; that is, one lies right on top of the other. Thus, there are infinitely many solutions.
Answer:
25% is called a quarter of 900
Step-by-step explanation:
Answer:
The explicit formula for the geometric sequence is 
.
Step-by-step explanation:
By definition of geometric sequence, we should use the following expression:
, 
(1)
Where:
- First term.
- Geometric rate.
- Position of the element within the series.
If we know that 
and 
, then the explicit formula for the geometric sequence is:
The explicit formula for the geometric sequence is .
Answer:
9π - 9
Step-by-step explanation:
Depends on what the question stated was pi (π). The area of the circle is 9(3 squared) * π. the shaded area is the area of the circle - the area of the triangle. The area of the triangle is base * high / 2. If the diameter of the circle (6) is what we use as the base, then 3 would be the high, making the area 9. This means the shaded area would be 9π - 9.
