Answer:

SA = 52900 + 2300√1313 m²

Step-by-step explanation:

The equation of the surface area of a pyramid:

SA = area of base + 0.5 * perimeter of base * slant height

1. Area of the base: Since it's a square base, 230² m² = <em>52900 m²</em>

2. Perimeter of the base: The base is square, 230*4 m = <em>920 m</em>

3. Slant height: 115² + 140² = h² --> h² = 32825 --> h = <em>5√1313 m</em>

Plug in: SA = 52900 + 0.5 * 920 * 5√1313

Multiply: SA = 52900 + 2300√1313 m²

you have a full job that pays 2400 per month you decide to take a part time job delivering newspapers that pay 200 per week if 1
lana [24]
Ft (full time)= $2,400/ monthpt (part time)= $200/ week15% taken from taxes------------------------- 1 year= 12 months; 1 month= 4 weeks (12*2,400) + (4*12*200)= $38,400 you made in a year I set up the problem this way because you want to know how much you made that whole year, so if there are 12 months in a year, and you get paid $2,400 a month, then from your full time job you ear (12*2,400). From your PT job you make $200 a week, there are 4 weeks in a month and 12 months in a year, so to calculate what you earned from your PT job, you do: 4*12*200 15% of what you made is deducted from taxes:0.15(38,400)= $5,760 After taxes, you made:$38,400-$5760= $32,640
