Melissa walked at a rate of 88 feet per minute. what was her approximate speed to the nearest tenth of a mile per hour? 0.1 miles per hour 1.0 miles per hour 2.8 miles per hour 8.8 miles per hour

Melissa walked at a rate of 1.0 miles per hour.

Step-by-step explanation:

As given

Melissa walked at a rate of 88 feet per minute .

As

Now convert 88 feet per minutes into miles per hour.

Therefore the Melissa walked at a rate of 1.0 miles per hour.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
