The HCF is the Highest Common Factor of a number in this case 54. This is the highest number times another number which = 54. The HCF for 54 is 18.
Answer:
1.21e+6 seconds
525,600 minutes
Step-by-step explanation:
Seconds in 1 day: 86,400
Seconds in 14 days: 1.21e+6
multiply the time value by 86400
525600
multiply the time value by 525600
Here, You need to apply "Proportionality Theorem"
According to this theorem, the ratio of components of a leg would be equal to the ratio of corresponding components of another leg.
In mathematical form,
TV/VS = TW/WU
Substitute their values,
14/6 = 21/(x+4)
14(x+4) = 21*6
14x+56 = 126
14x = 126-56
x = 70/14
x = 5
In short, Your Answer would be 5
Hope this helps!
