Answers

Answer 1

Answer:

Answer:

$Dave\ should\ buy\ 2735\ nails.$

Step-by-step explanation:

$Number\ of\ nails=70\n\nGood\ nails=64\n\npercentage\ of\ good\ nails=(good\ nails)/(total\ nails)* 100\n\npercentage\ of\ good\ nails=(64)/(70)* 100\n\npercentage\ of\ good\ nails=91.42857\%\n\nLet\ for\ 2500\ good\ nails\ he\ has\ to\ buy\ x\ nails\n\n91.42857\%\ of\ x=2500\n\n(91.42857)/(100)* x=2500\n\nx=(2500)/(0.9142857)=2734.375\n\nx\approx 2735$

The ratio of length to width in Gus's driveway is 13 yards to 4 yards . What is the ratio in feet?

Answers

Ratios have no units (as long as both numbers start out with
the same individual units), so the ratio doesn't depend on
the units (as long as both numbers start out with the same
individual units).

The ratio is still 13 to 4 , whether the top and bottom are both
converted to feet, Ångstroms, nanometers, inches, kilometers,
miles, or light-years.

Alana and Petra go to a used book sale, where every book is the same price. Alana buys 5 books and Petra buys 4 books. They run into their friend Angus, who really loves to read, and discover that he has bought 19 books. Angus received a $10.00 discount, but he still spent $7.50 more than Alana and Petra combined. How much does one book cost?

Answers

Answer:

Cost of one book is $1.75.

Step-by-step explanation:

Let the cost of one book is $x.

Alana and Petra brought 5 + 4 = 9 books together.

⇒ Cost of book brought by them together is $9x

Angus brought 19 books and he gets $10 discount.

⇒ He paid for book is $19x - 10

But also Angus spent $7.5 more than Alana and Petra

⇒ 19x - 10 = 9x + 7.5

⇒ 10x = 17.5

⇒ x = 1.75

Thus the Cost of one book is $1.75.
