5 0

0.72 repeating is the sum of a geometric series with first term 0.72 and common factor 1/100. The sum is given by:

(first term) 0.72 0.72 72

--------------------------- = --------------- = ------------ = ------------

1 - common factor 1 - 1/100 99/100 99

This 72/99 can be reduced to 8/11.

0.72 repeating can be rewritten as the fraction 8/11.

kirza4 [7]

Answer:

The total price is $5720

Step-by-step explanation:

According to the given statement a bedroom set lists for $7,000 and carries a trade discount of 20 percent. Freight (FOB shipping point) of $120 is not of the list price.

A bedroom lists for = $7000

Discount = 20% = 0.2

Now multiply 7000 by 0.2 = 7000* 0.2 = 1400

It means the discount value was $1400

Now subtract 1400 from 7000 = 7000 - 1400 = $5600

Now to get the total price add 5600 with 120 we get,

$5600+120 = $5720

Thus the total price is $5720 .....

How many pieces 6 1/4 in. long can be cut from 35 metal rods each 40 in. long?
viva [34]

We want to cut pieces of length:

l_P=6\frac{1}{4}in=(6+\frac{1}{4})in=(\frac{24}{4}+\frac{1}{4})in=\frac{25}{4}in=6.25in

from 35 metal rods each 40in long, and we want to know how many we can cut.

In order to answer the question, we must compute the number of pieces that we can cut from each metal rod, and then multiply the result by the number of metal rods. Let's do that!

1) From each metal rod we can cut:

\frac{l_R}{l_P}=\frac{40in}{6.25in}=6.4\rightarrow6\text{ pieces}

2) We have 35 metal rods, so the total number of pieces of 6 1/4 in that we can cut is:

35\cdot6=210

Answer

We can cut 210 pieces from the 35 metal rods.

Remark: we see that by cutting the pieces we will have a waste of metal from each rod.
