Omar has 2 3/4 cups of dough to make Dumplings. If he uses 3/16 cup of dough for each dumpling,how many whole dumplings can Omar
Brrunno [24]

Omar can make 14 whole dumplings. You change 2 3/4 cups to an improper fraction ( multiply the denominator and add the numerator ) and you get 11/4. Since you need 3/16 cups for one dumpling you have to find the greatest common denominator which is 16. You multiply 4 by 11 to get the numerator and end up with 44/16. Since you need 3/16 for one whole dumping you divide 44 by 3 and get 14.6 repeating. You cannot have a fraction of a dumpling so you round down and get the answer 14.

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
