Ximena bikes 20 miles from her home to her favorite lunch spot and then bikes back. She bikes
with the wind to lunch and against the wind on the way home. Her total travel time on the bike is 3.5 hours. When biking with no wind her average speed is 14 miles per hour.

1. Write and solve an equation to calculate the average speed of the wind. Show your work.

3.5x+20

the wind is around 7mph

Step-by-step explanation:

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

why? because i noticed a pattern. 60 120. those numbers without the zero, make the 6 times tables leaving your answer to be b since 6 times 4 is 24 and adding a zero making it 240.
