I believe this situation pertains to "two individuals," though I consider a 16-inch pizza to be more than sufficient. Apologies if I'm mistaken.

The number of people it serves is determined by the pizza's area.
First, we need to calculate the area of both the 8-inch pizza and the 16-inch pizza.


A = pi*r^2
For the 8-inch pizza:
diameter = 8 inches; radius = 4 inches
Thus, A = pi * (4 in)^2 = 16pi in^2.
For the 16-inch pizza:
diameter = 16 inches; radius = 8 inches
This results in A = pi * (8 in)^2 = 64pi in^2.
The area of the 8-inch pizza is 16pi in^2.
Conversely, the area of the 16-inch pizza is 64pi in^2.

Next, we find out how many times larger the area of the 16-inch pizza is compared to the 8-inch pizza.
Thus, ratio = (64pi in^2)/(16pi in^2) = 64/16 = 4.
A 16-inch pizza has an area four times that of an 8-inch pizza.
Since an 8-inch pizza is sufficient for one person, the larger 16-inch pizza can accommodate 4 individuals.

Stefan's family rented a rototiller to prepare an area in their backyard for spring planting. The rental company charged an init
lawyer [4008]

Answer: The hourly charge for the rototiller is $3.

Step-by-step explanation:

Let h denote the hourly rate for the rototiller rental.

The rental provider imposed a base fee of $43 in addition to a charge per hour. Assuming the rototiller was rented for x hours, the cost incurred would total

43 + hx.

If they paid $64 for 7 hours of rental, the equation representing this situation would be

43 + 7h = 64.

Resolving gives us 7h = 64 - 43 = 21.

Therefore, h = 21/7 = $3.

What is the solution to the linear equation? 2.8y + 6 + 0.2y = 5y – 14 y = –10 y = –1 y = 1 y = 10
Zina [3914]

2.8y + 6 + 0.2y = 5y – 14

Start by simplifying the left side:

3y + 6 = 5y - 14

Next, deduct 3y from both sides:

6 = 2y - 14

Add 14 to both sides:

2y = 20

Now, divide by 2:

y = 20 / 2

y = 10

Given that Ray E B bisects ∠CEA, which statements must be true? Select three options. m∠CEA = 90° m∠CEF = m∠CEA + m∠BEF m∠CEB =
PIT_PIT [3919]

Answer:

mCEA = 90ᴼ, as CEA forms a right angle, and by definition, right angles measure 90ᴼ.

The angle CEF is classified as a straight angle as it combines two right angles (CEA and AEF), equating to 180ᴼ altogether. Straight lines are defined to measure 180ᴼ.

AEF is determined to be a right angle as CEA is already a right angle, and since CEF is a straight line, AEF must also be a right angle.

Leona [4166]

Answer:

The earnings gap, over a career spanning 30 years, between men and women totals $1,200,150

Step-by-step explanation:

Calculated annually.

The typical male earns $90,761 each year.

The typical female earns $50,756 per annum.

Therefore, the annual difference is:

90,761 - 50,756 = 40,005

Across 30 years:

30*40,005 = 1,200,150

The earnings gap over a 30-year career, when comparing men and women, is $1,200,150
