20 divided by 2 equal 10 and the rest are counting by twos please
Answer: b
the answer is b
in order to solve for AB you need to use the pythagorean theorem by making a triangle with AB as one of the sides of the triangle.
plot each point A and B and connect it and connect point B with the x-axis, (3,0) You'll see athat a triangle has formed. All you have to do after that is apply the Pythagorean theorem.
the distance from A to the new point (3,0) is 3, the distance from the new point to B is 4. Line AB will be the hypotenuse.
Pythagorean therom is a^2+b^2=c^2
so 3^2+4^2=c^2
= 9+16=25
square root the 25 and you get a 5.
Answer: the speed of the commercial jet is 540 mph
the speed of the private airplane is 330 mph
Step-by-step explanation:
Let x represent the speed of the commercial jet and
Let y represent the speed of the private airplane.
It takes the commercial jet 1.1 hours for the flight from Denver to Phoenix.
Distance = speed × time
Therefore, distance covered by the commercial jet from Denver to Phoenix would be
1.1 × x = 1.1x
it takes the private airplane 1.8 hours to cover the same distance. The speed of the commercial jet is 210 miles per hour faster than the speed of the private airplane. It means that
y = x - 210
Distance covered by the private airplane would be
1.8(x - 210) = 1.8x - 378
Since the distance is the same, then
1.8x - 378 = 1.1x
1.8x - 1.1x = 378
0.7x = 378
x = 378/0.7 = 540
y = x - 210 = 540 - 210
y = 330
