Answer:
Approximately 35, or 34.67
Step-by-step explanation:
You can set up a cosine (adjacent over hypotenuse) equation.
cos38 = x/44
Move the 44 over and plug into the calcultaor.
x = 44cos38
(make sure the mode is on degree and not radian!)
Answer:
x ≤ - 27
Step-by-step explanation:
Given
≥ 3
Multiply both sides by - 9, reversing the symbol as a result of multiplying by a negative quantity.
x ≤ - 27
Answer:
y = x + 6.
Step-by-step explanation:
y = mx + c where m = the slope of the line and c is the y-intercept.
So here m = 4/4 = 1 and c = 6, so it's:
y = 1x + 6.
Answer:
680
Step-by-step explanation:
Number of red beans = 30
Number of Blue beans = 30
Number of green beans = 30
How many color combinations of 15 beans have at least 6 green beans?
Since at least 6 of the beans must be green,
Then (15 - 6) = 9
Then, the remaining 9 could be either red, blue or green.
Therefore, C(9 + (9 - 1), 3)
C(17, 3) = 17C3
nCr = n! ÷ (n-r)! r!
17C3 = 17! ÷ (17 - 3)! 3!
17C3 = 17! ÷ 14!3!
17C3 = (17 * 16 * 15) / (3 * 2)
17C3 = 4080 / 6
17C3 = 680 ways
