Raquel has created a program for a robot. The robot travels 10 meters and stops. The program is designed for wheels that are 2.5
Grace [21]

Answer:

Raquel should adjust the number of rotations  to 115.81 rotations

Step-by-step explanation:

step 1

Find the circumference of the wheels that are 2.5 cm in diameter

The circumference is equal to

C=2\pi r

we have

r=2.5/2=1.25\ cm

assume

\pi =3.14

substitute

C=2(3.14) (1.25)

C=7.85\ cm

step 2

Find the number of rotations

Divide 10 meters by the circumference

10\ m=1,000\ cm

1,000/7.85=127.39\ rotations

step 3

For a diameter of 2.75 cm find how should she adjust the number of rotations so that the robot travels the same distance

Find the circumference of the wheels

The circumference is equal to

C=2\pi r

we have

r=2.75/2=1.375\ cm

assume

\pi =3.14

substitute

C=2(3.14) (1.375)

C=8.635\ cm

step 4

Find the number of rotations

Divide 10 meters by the circumference

10\ m=1,000\ cm

1,000/8.635=115.81\ rotations

Determine the value of the variable. 5 + 17 = J - 14
Nataly_w [17]
You would add 5 and 17 and that would equal 22
Now it would be 22=J-14
Then add 14 on both sides so it cancels out 22 plus 14 is 36
So J would equal 36
