koban [17]

Answer:

chocolate bar - 1 (whole number)

Step-by-step explanation:

1 -   \frac{1}{3}   \\  >  \frac{3}{3}  -  \frac{1}{3}  =  \frac{2}{3}

\frac{2}{3}  -  \frac{3}{4}  \\  >  \frac{2 \times 4}{3 \times 4}  -  \frac{3 \times 3}{4 \times 3}  \\   \\  \\  >  \frac{8}{12}  -  \frac{9}{12}

so I switch it become

\frac{9}{12}  -  \frac{8}{12}  =  \frac{1}{12}

Arthur ran around a circular field 3 times. If he ran a total of 750m what is diameter and radius
Dmitrij [34]

Answer:

Hope this helped

Step-by-step explanation:

Circumference = 750 m / 3

Circumference 250 m

Circumference = pi * D where pi = 3.1415926 and D is the diameter in meters

Solving for the diameter

250 m = pi * D

D = 250 m / pi

D = 79.58 m is the diameter of the circular field

Solving for the radius

r = 1/2 D where r is the radius of the circular field

r = 39.59 m is the radius of the circular field
