;lolokStep-by-step explanation:
The planes will pass each other in 1.14 hours.
Why?
To solve the problem, we must remember that since both planes are heading toward each other, the speed to the calculations will be their combined speeds.
The speed will be:

Now, calculating the time, we have:

Hence, the planes will pass each other in 1.14 hours.
Have a nice day!

<h3>The measure of third angle of triangle is 67 degrees</h3>
<em><u>Solution:</u></em>
Given that,
The support of a wood table are in the shape of a right triangle
Since it is a right angle, one of the angle must be 
The measure of one of the angles is 23 degrees
To find: third angle angle
We know that,
Sum of all angles in triangle equals 180 degrees
Therefore,

Thus measure of third angle of triangle is 67 degrees
Answer:
the cost function is Cost=7000 m*$ /R + 50.265 $/m² * R²
Step-by-step explanation:
then the cost function is
Cost= cost of side area+ cost of top + cost of bottom = 2*π*R*L * 5$/m² +
π*R² * 8$/m² + π*R² * 8$/m²
since the volume V is
V=π*R²*L → V/(π*R²)=L
then
Cost=2*π*R*V/(π*R²) * 5$/m² + π*R² * 8$/m² + π*R² * 8$/m²
replacing values
Cost=2*700 m³ /R * 5$/m² + π*R² * 16$/m² = 7000 m*$ /R + 50.265 $/m² * R²
thus the cost function is
Cost=7000 m*$ /R + 50.265 $/m² * R²
