Answer:
Step-by-step explanation:
Assumed the starting point is the sea level 0.
<u>After 2.8 min the diver is at position:</u>
- 20 1/2 * 2.8 =
- 20.5 * 2.8 =
- 57.4 feet below sea level
<u>The position change after next 2 minutes:</u>
<u>The position of the diver after 4.8 min:</u>
- 57.4 - 50 = 7.4 feet below sea level
I can't figure out a factor for this but graphing it shows x = -2 and +1 as real roots.
Answer:
2800 - 4000
Step-by-step explanation:
40 × 70 = 2800
50 × 80 = 4000
Circumference = 2 * pi * r, where r is the radius
For this circle, the circumference is 11pi, so 11pi=2*pi*radius. Divide both sides by 2pi and you get r is = to 5.5 inches.
Area of a circle is pi*r^2. Since we just saw that r = 5.5 inches, the circle has an area of 5.5 inches * 5.5 inches * pi or 30.25 pi inches squared.
Answer:
32,000 square feet gross area and 28,750 square feet net area
Step-by-step explanation:
Given a rectangular site measures 125 feet (frontage) by 256 feet (depth), of which 26 feet is in the public right of way. We have to find the the gross and net site area.
As, 26 feet width is in the public right of way which excluded in the net area but included in gross area.
For gross area,
Length=125 feet
Width=256 feet

For net area,
Length=125 feet
Width=256-26=230 feet

Hence, last option is correct.
The answer is: 32,000 square feet gross area and 28,750 square feet net area
