A yo-yo factory has fixed operating costs of $5000 per day plus costs of $2 per yo-yo produced. If a yo-yo sells for $5.50, what

Jlenok [28]

Answer:

1429

Step-by-step explanation:

Break even is expressed as:

5000+2x = 5.5x

5000=5.5x-2x

5000=3.5x

$\frac{5000}{3.5} = \frac{3.5x}{3.5}$

1428.57=x

Since you cannot sell a fractional yo-yo, round up to 1429

The surface area of this regular pyramid is 1040 cm2. The base is a regular pentagon with side b = 16 cm and slant height l =15

Valentin [98]

Answer:

(a) = 11 cm

Step-by-step explanation:

The formula for finding the surface area of a regular pyramid is B + (1/2*P*l), with B being the area of the base, p being the perimeter of the base, and l being the slant of the pyramid.

The area of a pentagon can be solved using the formula 1/2*a*p, with a being the apothem and p being the perimeter of the pentagon.

B + (1/2*80*15) = 1040
B + 600 = 1040
1040 - 600 = 440 (440 is the area of pentagon)
1/2*a*(16*5) = 440
40*a = 440
440/40 = 11

The apothem is 11 cm. Hope this helps!
