Answer:6.0002inch
Step-by-step explanation:
Volume of sphere=904.39
π=3.14
Volume of sphere=4/3 xπ x r^3
904.39=4/3 x 3.14 x r^3
904.39=(4x3.14xr^3) ➗ 3
904.39=(12.56xr^3) ➗ 3
Cross multiplying we get
904.39x3=12.56xr^3
2713.17=12.56xr^3
r^3=2713.17 ➗ 12.56
r^3=216.02
Taking the cube root of both sides
r=3√216.02
r=6.0002
Step-by-step explanation:
240 miles = 9 gallons of gas
1 mile = 9/240
= 3/80 (0.0375) gallons of gas
216 miles = 3/80 (0.0375) × 216
= 8.1 gallons of gas
Answer:
Step-by-step explanation:
step 1
Find the slope of the line
The formula to calculate the slope between two points is equal to
we have the points
(2,24) and (6,16)
substitute in the formula
step 2
Find the equation of the line in slope intercept form
we have
----> the k-intercept is the point (0,28) see the graph
substitute
To solve for x^2 - 40 = 9, take the square roots of both sides and solve.
The answer is x = 7, -7.
