1 stack of nickels is S=45gm; given that there are 9 nickels on each stack you can divide the mass of the stack(45) by the number of nickels in a stack(9) to find the mass of 1 single nickel 

\frac{45gm}{9}=5gm 

<u>5gm = 1 nickel</u>

A killer whale can swim 40 miles in 1 1/4 hours. how far can the whale swim in an hour?
bogdanovich [222]
Okay so 1 \frac{1}{4} = 75 minutes. Now we divide 40 by 75. 40÷75=0.53333333333333 miles. We know 1 hour is 60 minutes so we are going to multiply 0.5333333333333 by 60. 60×0.533333333333=32 miles. Therefore, your answer is 32 miles.

A software store has put some of its inventory on sale. Games are marked down by 15%, and security programs are marked down by 1
Katyanochek1 [597]

Answer:

Option D. \$11.34

Step-by-step explanation:

Let

x -----> the original price of one game

y ----> the original price of one security programs

Remember that

100\%-15\%=85\%=85\100=0.85

100\%-18\%=82\%=82\100=0.82

The total pay with discount is

\$35.70+\$22.96=\$58.66

we have that

0.85(2x)=35.70\\1.70x=35.70\\x=\$21

0.82y=22.96\\y=\$28

Find the total pay without discount

2x+y=2(21)+28=\$70

The amount saved is the difference

\$70-\$58.66=\$11.34
