Answer:
equation: y = 500x + 3,000
Step-by-step explanation:
The slope is 500 because it is gaining 500 gallons of water every hour. The y-intercept is 3,000 because the pool started off with 3,000 gallons in it.
42:35 or if simplified 6:5
Answer:
100+90+7
200+20
Step-by-step explanation:
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!
