Answer:
6 : 16, 12 : 32 and 18 : 48.
Step-by-step explanation:
Therefore, the three equivalent ratios of 3 : 8 are 6 : 16, 12 : 32 and 18 : 48.
Step-by-step explanation:
C = 2πr = 53.38cm
r = C / 2π = 53.38cm / 2π = 53.38/ 6.283185307179586 = 8.4956cm
A = πr^2 = π × (8.4956cm^)2 = 226.4cm^2
Answer:
y/4 + x/12
Step-by-step explanation:
The number of working toys = x
The number of broken toys = y
Bert breaks 1/3 of the working toys, that is:
1/3 * x = x/3
The number of broken toys is now:
y + x/3
Ernie then throws away 1/4 of the broken toys. In terms of x and y, the number of broken toys that Ernie threw away is:
1/4 *(y + x/3)
= y/4 + x/12
