3/8 because 1/4 is equal to 2/8.
Working fast here ... try to keep up:
You said x/20 = 12/16
Multiply each side by 20 : x = 20 x 12/16
= 240 / 16 = 15 .
The volume of a sphere is (4πr^3)/3 and since r=d/2, volume of a given sphere with respect to its diameter is:
V=(4πd^3)/24
V=(πd^3)/6 in this case d=8.65 so
V≈338.88 in^3 (to the nearest hundredth)
Answer:
168 miles.
Step-by-step explanation:
5/7x+40+0.75x−118=x
Step 1: Simplify both sides of the equation.
5/7x+40+0.75x−118=x
5/7x+40+0.75x+−118=x
(5/7x+0.75x)+(40+−118)=x(Combine Like Terms)
1.464286x+−78=x
1.464286x−78=x
Step 2: Subtract x from both sides.
1.464286x−78−x=x−x
0.464286x−78=0
Step 3: Add 78 to both sides.
0.464286x−78+78=0+78
0.464286x=78
Step 4: Divide both sides by 0.464286.
0.464286x/0.464286=78/0.464286
x=168
