Answer:

The cost per square inch for the NY pizza is $0.08.

Step-by-step explanation:

To solve this problem we first need to calculate the area of each pizza, since they're circular their area is given by:

area = pi*r² = pi*(d/2)²

Chicago:

area = 3.14*(14/2)² = 153.86 square inches

NY:

area = 3.14*(18/2)² = 254.34 square inches

The cost per square inch is given by the cost of the pizza divided by it's area. So for NY:

cost per square inch = 20.99/254.34 = $0.08 per square inch

<u>Example: </u>

  • 1 meter = 1000 millimeters (1.0 m = 1000.0 mm)

<h2>Answer:</h2>

D. \ 408in^2

<h2>Step-by-step explanation:</h2>

This is a square pyramid because it's a solid having a square base. The point up the pyramid is called the apex and is directly above the middle of the square base. The surface area of a solid is the total area of its outer surface. If we unfold this pyramid, we'll get one square and four identical triangles. So the surface are can be calculated as follows:

s=s_{square}+4s_{triangle}

FOR THE SQUARE:

s_{square}=L^2 \\ \\ L=12in \\ \\ s_{square}=12^2=144in^2

FOR THE TRIANGLE:

s_{triangle}=\frac{bh}{2} \\ \\ b=12in \\ h=11in \\ \\ s_{triangle}=\frac{12\times 11}{2}=66in^2

Finally:

s=s_{square}+4s_{triangle} \\ \\ s=144+4(66) \\ \\ s=144+264 \\ \\ \boxed{s=408in^2}

A senior class of 420 students will rent buses and vans for a class trip. Each bus can transport 50 students and 3 chaperones an
kykrilka [37]

Answer:

37 buses and 1 van.

Step-by-step explanation:

The cost to rent a van is $1200 for 50 students and 3 chaperones, while a bus for 10 students and a chaperone is $100 .

The cost of renting buses for 50 students is $500

What we do is rent 37 buses and 1 van

37 buses will take in 370 students with empty 2 spaces in 2 buses for chaperones since the chaperones are 36.

Then rent 1 van to take in 50 students and 1 chaperone.

The total cost here will be

$3700 + $1200 = $ 4900

This will help to safe cost.
