Step-by-step explanation:
A. 3n = 33
n = 33/ 3 = 11
B. 9 + w = 10
w = 10 - 9 = 1
C. r - 15 = 30
r = 30 + 15 = 45
D. 2y + 3 = 11
2y = 11 - 3
2y = 9
Y = 9/2
Answer:
<em>A) The reference angle should be </em><u><em>,</em></u><em> and the sign of the value should be </em><u><em>negative.</em></u>
Step-by-step explanation:
cos()
Remove full rotations of 2π until the angle is between 0 and 2.
cos()
Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because cosine is negative in the third quadrant.
-cos()
The exact value of cos() is .

Answer:
The fraction of one pound of cheese to be used in each sandwich is 1/8
Step-by-step explanation:
Here, we have a question that requires the method of dealing with the division of fractions.
To divide a fraction by a whole number, we multiply the denominator of the fraction by the whole number as follows;
Quantity of cheese Shane has = 1/2 pound
Number of sandwiches to be made = 4
Amount of cheese per sandwich = 1/2÷4 = 1/8.
Divide 500 by 400 and you'll get 1.25m/sec.
