Answer:
The water is 208.22ft from the tug boat
Step-by-step explanation:
The governing equation is 
y is the height above the ocean
x is the distance from the tugboat
if y= 6ft, the equation will now become
we can arrange this properly to form a quadratic equation by grouping like terms.
solving quadratically we have two values of x as 208.22ft and 0.873 ft.
We can take a more realistic value as a solution to our problems:
208.22ft
Answer:
70 and 110
Step-by-step explanation:
The two angles add to 180 degrees since they form a straight line
2x+10 +3x+20 =180
5x+30 = 180
Subtract 30 from each side
5x+30-30 =180-30
5x = 150
Divide by 5
5x/5 =180/5
x = 30
The left angle is 2x+10 = 2*30+10 = 60+10 =70
The right angle is 3x+20 = 3*30 +20 = 90+20 = 110
Answer:
<h3>y = 1</h3>
Step-by-step explanation:
Correct question
The points ( 2,4) and (5,y) lie on the same line. If the slope of the line is --1, what is the value of y
The formula for calculating slope of a line is expressed as;
m = y2-y1/x2-x1
Substitute the given point
y - 4/5-2 = -1
y-4/3 = -1
y-4 = -3
y = -3+4
y = 1
Hence the value of y is 1
Answer:
17 wings
Step-by-step explanation:
Money/How Many
19.60/14=1.4
1.4 is the unit rate, so we divide 23.80/1.4 to find how many chicken wings
which equals 17
