Answer:
36 kg
Step-by-step explanation:
Let m = mass of green tea.
The total mixture should be (18*3.5+2.6*m)/(18+m) = 2.9
The numerator is $, denominator is kg
Therefore 63+2.6m = 52.2+2.9m
0.3m = 10.8
3m = 108
m = 36
Answer:
the plane's current height above the ocean is 3.42 miles
Step-by-step explanation:
Given that the diagonal distance between the plane and the aircraft carrier is 10 miles.
What we need to find is the vertical distance between the plane and the aircraft carrier which is the plane's current height above the ocean. This can be gotten using sine rule.
For sine rule, you need a side and its opposite angle. For this question the triangle formed is a right angle triangle with diagonal distance, vertical distance and horizontal distance.
let a = diagonal distance = 10 miles
let the opposite angle to the diagonal distance be A = 90° (right angle)
let the vertical distance = b
let the opposite angle to the vertical distance be B = 20°
Sine rule states that 
∴ 


⇒ b = 3.42 miles
Therefore the plane's current height above the ocean is 3.42 miles
Answer:
Step-by-step explanation:
The slope of a line between two points can be calculated by dividing the difference of y values by the difference of x values
in this case

Step-by-step explanation:
C=4x+3y Constraints: x is greater than or equal to 0 2x + 3y is greater than or equal to 6 3x - 2y is less than or equal to 9 x + 5y is less than or equal to 20
The solution can be anything bigger than 13/6.
For example: 3, 4, 5, 6...ect
