Let the numbers be x and y.
x*y=HCF*LCM=6*60=360
thus
y=360/x
next we find the list of combinations of x and y and test if they satisfy the conditions above:
(6,60),(12,30),(18,20),(24,15)
out of the above, only (6,60) and (12,30) satisfy both conditions. Thus our answer is:
(6,60) or (12,30)

10 yards 1 foot 9 inches divided by 3

AysviL [449]

Answer:

127 inches

Step-by-step explanation:

A single yard is equal to 3 feet. So one yard 1 foot and 9 inches is:

$3(10)+1$ and 9 inches.

each feet has 12 inches, so it goes something like this:

$12(31)+9$ inches

multiply it out:

$372+9\\381$

Thats the total number of inches, now we divide by 3 (use long division:

$\frac{381}{3}=127$

Hope this helps!

If the world's population increased exponentially from billion in 1998 to billion in 2008 and continued to increase at the same

Gelneren [198K]

Answer:

The answer is "7.122 billion"

Step-by-step explanation:

Please find the complete question in the attached file.

Using formula:

$\to y=Ce^{kt}$

$C=5.937\\\\y=6.771\\\\t=10\\\\ k=?6.771=5.937e^{10k}\\\\1.1405=e^{10k}\\\\\ln(1.1405)={10\ k}\\\\0.013={k}\\\\$

So,

$\to y=5.937e^{.013t}\\\\$

when it becomes $2012, \ t=14$ so plug the value into the formula

$\to y= 5.937e^{.013(14)} =7.122 \ billion$
