5/12 and 3/8 is the answer
We need the circumference and area of the circle equations:
c = 2*pi*r
a = pi*r^2
lets find the radius from the first equation:
r = c/2*pi
r = 157/(2*3.14)
r = 24.99 ft
now lets calculate the area:
a = pi*r^2
a = 3.14*(24.99)^2
a = 1960.93 ft^2
Now we need to divide the total area by the rate at which Chris paints, and that gives us the time needed:
time = <span>1960.93/400
time = 4.9 hours
that would be 5 hours rounded to the nearest hour</span>
Answer:
<h2>e = 1.75</h2>
Step-by-step explanation:
11,580 to 3 significant figures
Currently, the value has 5 significant figures ( inclusive of 0 )
next to 5, there is 8 and 8 > 5, so 5 rounds up
1.16 x 10⁴
Answer:
x=3/10y+-1/2
Step-by-step explanation:
Add -3y to both sides
-10x+3y=5
-3y -3y
-10x=3y+5
Divide both sides by -10
-10x=3y+5
_________
-10 -10
x=3/10y+-1/2
