There are 500 toothpicks in a small box. if a jumbo box is made by doubling all the dimensions of the small box, how many toothpicks will the jumbo box hold?
a. 2,000 tooth picks
b. 8,000 tooth picks
c. 1,000 tooth picks
d. 4,000 tooth picks

Option: D is the correct answer.

D. 4000 Tooth picks.

Step-by-step explanation:

It is given that:

There are 500 toothpicks in a small box.

so, let the dimensions of small box be:

x units×y units×z units.

This means that the volume of the small box is:

Volume(V)=xyz cubic units.

Now a jumbo box is made by doubling all the dimensions of the small box.

This means that the dimensions of the jumbo box are:

2x units×2y units×2z units.

Hence, the volume of jumbo box is:

Volume(V')=8xyz cubic units.

As the number of toothpicks hold by a box of volume xyz cubic units are:500.

So, the number of toothpicks hold by a box of volume 8xyz cubic units will be:8×(500)=4000

Hence, the number of toothpicks that jumbo box can hold are:

D. 4,000 Tooth Picks

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
