Answer/Step-by-step explanation:
The diagram of the circular track is missing, and so also its dimensions.
However, let's assume the dimensions of the circular track given is diameter (d) = 20 meters or radius (r) = 10 meters.
Since it's a circular track, the circumference of the track would give us the number of meters she runs in 1 lap.
Circumference = πd
d = 20 m (we are assuming the diameter is 20 meters)
π = 3.14
Circumference of circular track = 3.14 × 20 = 62.8 m.
This means that 1 lap = 62.8 m that she would have to run.
Therefore,
6 laps would be = 6 × 62.8 = 376.8 m
Therefore, if she completes 6 laps around the circular track that has a diameter of 20 m, she will have to run about 376.8 m.
Given:
The given expression is
To find:
The value of given expression.
Solution:
We have,
Applying the negative exponents rule, we get
Expanding the exponent, we get
The value of given expression is .
Therefore, the correct option is A.
C8=m
The dozens of cupcakes she sells, multiplied by 8, is equal to the money she earns.
Hope this helps!
1/4 = 4/16
six month improvement-> 7/16-4/16 =3/16
after another six months-> 7/16+3/16=10/16
Ans:10/16
The answer is A B or C and possibly D
