Answer:
C. 47°
Step-by-step explanation:
The angle between the terminal ray of 227° and the nearest x-axis (the negative x-axis) is ...
227° -180° = 47°
The reference angle is 47°.
_____
In mathematical terms the reference angle is the minimum of the angle modulo 180° and the supplement of that angle.
227° modulo 180° = 47°
180° -47° = 133° . . . . supplement of 47°
min(47°, 133°) = 47° . . . the reference angle
That would be 16(1/4)^(n-1)
for example 4th term = 16(1/4)^3 = 1/4
Two angles are called complementary when their measures add to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees.So the equation to solve this would be simply 90 multiply 2 which gives you the answer of 180 degree in this situation.
Answer:
$35
Step-by-step explanation:
10% + 20% = 30%
You spent 30% of the $50 clothes and games.
You spent the rest on books.
100% - 30% = 70%
You spend 70% on books.
70% of $50 = 0.70 × $50 = $35
Answer: $35
A good way to see what Shelby first did is to turn the amount she says she made into an improper fraction. You do this by multiplying the number to the left of the fraction by the denominator and adding it to the top. This shows Shelby divided 7 by 4 to get her 1 3/4 cups of juice answer. Since Shelby divided, a good option would be to try and multiply the original 7 amount by 4, as there is also 4 cups in a single quart, so 7 times 4. This number will be how many cups of juice she made.
