Answer:

The larger pizza is less expensive per square inch

Step-by-step explanation:

we know that

The area of a circle (pizza) is equal to

A=\pi r^{2}

step 1

<em>Find the area of the smaller pizza</em>

we have

r=10/2=5\ in ----> the radius is half the diameter

substitute

A=(3.14)(5)^{2}=78.5\ in^{2}

Find the price per square unit

Remember that

The price of one smaller pizza is \$15/2=\$7.5

so

\frac{7.5}{78.5}\frac{\$}{in^{2}}=0.10\frac{\$}{in^{2}}

step 2

<em>Find the area of the larger pizza</em>

we have

r=16/2=8\ in ----> the radius is half the diameter

substitute

A=(3.14)(8)^{2}=200.96\ in^{2}

Find the price per square unit

so

\frac{17}{200.96}\frac{\$}{in^{2}}=0.08\frac{\$}{in^{2}}

Therefore

The larger pizza is less expensive per square inch

A change machine changes dollar bills into quarters and nickels. If you receive 12 coins after inserting a dollar bill, how many
Rudik [331]
Well, given that a quarter equals 5 nickels, we can reason that, in order to get 12 coins, we would have to get 10 nickels (equals 50 cents) and 2 quarters (the other 50 cents, to make a dollar).

You didn't say whether you needed this expressed in a mathematical formula, but knowing the answer already, it shouldn't be hard to come up with one if necessary.

Hope this helps.
