5 pigs: 3 chickens
pigs have four feet, so if 20 feet belong to the pigs, there's 5 pigs, because 5x4=20.
chickens have 2 feet, so if 6 feet belong to the chickens, there's 3 chickens, because 2x3=6.
Length of the cube = 7
Working:
Cube root of 343 =7
(or)
7^3=7*7*7=343
Answer:
4/5
Step-by-step explanation:
we divide by 3 the numerator and the denominator:
(12/3) / (15/3)
we have:
4/5
Answer:
Option B
Step-by-step explanation:
Since, number of calories 'C' burned is proportional to the number of minutes (m) given to the exercise,
C ∝ m
C = km
Where k is the proportionality constant.
From the table attached,
For C = 250 calories and m = 30 minutes,
250 = 30k
k = 
= 
Therefore, equation representing this situation will be,
C = 
Option B will be the correct option.
