A jar contains $36.25 in quarters and nickels. How many quarters and dimes are in the jar? Please explain how u got the answer,
kumpel [21]
So, look:

36*4 = 144

There are 145 quarters in all.

And in nickels, there are:

144 * 5 = 720 + 5 = 725
There are 725 nickels in all.

Dimes: 144 * 10 = 1440 + 10 = 1450  (or you could do 145 * 10 and still get 1450. Like I did in the nickels and everything. :) )

= 1450 dimes 

I hope this helps!

She has 10,000 glass beads that have a diameter of 0.4 cm.If she strings these beads end to end, how long will her necklaces be?
faltersainse [42]

As given,

The diameter of one glass bead = 0.4 cm

As the beads are stringed/attached end to end that means a straight line of beads (diameter) can be imagined and adding up all the diameters or multiplying the diameter with total number of beads, we can get the total length of the necklace.

Hence, the length can be found as =

10000\times0.4=4000 cm

or converting this in meters we get \frac{4000}{100}=40 meter

Hence, the necklace will me 40 meters long.
