1. You have that the Standard form for the equation of a circle when its center is at the origin, is:
x²+y²=r²
2. You must calculate the radius. Then:
r=√(x²+y²)
x=24
y=32
3. When you substitute the values of "x" and "y" into the equation r=√(x²+y²), you obtain:
r=√(x²+y²)
r=√(24²+32²)
r=√(576+1024)
r=√1600
r=40 feet
4. Therefore, the diameter (D) of the circle, is:
D=2r
D=2(40 feet)
D=80 feet
Answer:
59.25 < hb ≤ 86.25 (also = 59.3 < 1dp ≤ 86.2 to 1dp)
Step-by-step explanation:
60- 0.75 = human height therefore 59.25 < h ≤ ? then to find greatest height we subtract again 87 - 0.75 = 86.25 and fill in 59.25 < h ≤ ? = 59.25 < h ≤ 86.25 and should we show inhes to 1 dp we keep lowest rounded up 59.3 < 1dp ≤ 86.2 as lowest bound is 59.15 < lb ≤ 86.15 = 59.25 < hb ≤ 86.25

Answer:
11.5 hours
Step-by-step explanation:
25 pages every 75 minutes (1 1/4)
Thats means 1 page every 3 minutes (divide 25 and 75 by 25 to get this)
230 pages would mean 690 minutes (times the 3 by 230)
690/6 = 11.5
Answer:
2 hours and 5 minutes
Step-by-step explanation:
50/40=1.25 km/m
100*1.25=125 minutes
125 minutes= 2.08 hours= 2 hours and 5 minutes
