Answer:

The problem does not work.

Step-by-step explanation:

The plane with speed of 31 mph will cover 640 miles in \frac{640}{31} = 20.64 hours.

Now, it burns 5 gallons of gas every 3 minutes i.e. 0.05 hours.

So, it will burn in 20.64 hours \frac{5 \times 20.64}{0.05} = 2064 gallons.

Now, the helicopter with speed of 45 mph will cover 640 miles in \frac{640}{45} = 14.22 hours.

Now, it burns 7 gallons of gas every 5 minutes i.e. 0.083 hours.

So, it will burn in 14.22 hours \frac{7 \times 14.22}{0.083} = 1194.48 gallons.

But both of them starts with only 80 gallons of fuel.

Therefore, the problem does not work. (Answer)

What is the slope of a line perpendicular to the line with equation y = 1/6x – 2? help pls very urgent
valina [46]
Solution:

1) Simplify \frac{1}{6}x to \frac{x}{6}
y=\frac{x}{6}-2

2) Add 2 to both sides
y+2=\frac{x}{6}
​​
3) Multiply both sides by 6
(y+2)\times 6=x

4) Regroup terms
6(y+2)=x

5) Switch sides
x=6(y+2)

Done!

Find the gradient of the line l1 which has equation 4x-3y+5=0 .
Nikitich [7]

Answer:

The gradient is the same as the slope. To find the slope, let's convert this from standard form to slope-intercept form.

4x - 3y + 5 = 0

4x + 5 = 3y

4/3x + 5/3 = y therefore the answer is 4/3.
