You need to figure out the total area of the pizza (a circle) and then divide it by the area of each slice to get the number of slices of pizza. By the way, area should be in square units, so I assume you mean 14.125 in2.

So, Area of a circle = πr2

Diameter = 2 x the radius (r). So, if the diameter = 14 in, 14 in = 2 r, and dividing both side by 2, r = 7 in.

Area of a circle = Π (7 in)2 = 153.938 in2

Now, divide this total area of the pizza, 153.938 in2, by the area of one slice, 14.125 in2.

153.938 in2/14.125 in2 = 10.898 slices or about 11 slices of pizza

Elijah brought a total of 16 pounds of peanuts and cashew nuts and paid $49.50 if peanuts cost $2.75 per pound and cashews nuts
maria [59]

Answer:

The number of pounds of cashew is 11

Step-by-step explanation:

Let P represent the peanut

Let C represent the cashew nut.

From question, we were told that Elijah brought a total of 16 pounds of peanuts and cashew nuts. This can be written as:

P + C = 16 (1)

The total cost = $49.50

Cost per peanut = $2.75

Cost per cashew = $3.25

The above can be represented as:

49.50 = 2.75P + 3.25C. (2)

From equation 1,

P + C = 16

P = 16 — C

Substitute the value of P into equation 2:

49.50 = 2.75P + 3.25C.

49.50 = 2.75(16 — C) + 3.25C

49.50 = 44 — 2.75C + 3.25C

49.50 = 44 + 0.5C

Collect like terms

49.50 — 44 = 0.5C

5.5 = 0.5C

Divide both side by 0.5

C = 5.5/0.5

C = 11

Therefore, the number of pounds of cashew is 11
