Answer:
The other number is 330
Step-by-step explanation:
The computation of the other number is shown below:
As we know that
HCF × LCM = Product of Two Numbers
So,
30 × 2310 = 210 × other number
Now
The other number is
= (30 × 2310) ÷ 210
= 330
hence, the other number is 330 and the same is to be considered

The given formula is f(t) = 0.4t
They want to solve for f(10), replace t in the formula with 10"
f(10) = 0.4(10)
Multiply:
f(10) = 4 centimeters.
