answer is c ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,
csc(x) is the reciprocal of sin(x)
Since sin(x) = 6/7
Then to find csc (x) reciprocal to the value of sin(c)
csc(x) = 7/6
The answer is the first choice
Answer:
34 5/6
Step-by-step explanation:
Convert the mixed numbers into improper fractions:
57/10 × 55/9
We can reduce these fractions by using the greatest common factor, 3
19/2 × 11/3
Multiply
19/2 × 11/3 = 209/6
Convert to mixed number
209/6 = 34 5/6
He wants $2100 = 30%
2100 is 30% of x
y = p% * x
x = y/p%
x = 2100/30%
30/100 = 0.30
x = 2100/0.30
2100/0.30 = 7000
His monthly net income would need to be $7000
