Answer:
82.4 ft^3
Step-by-step explanation:
Diameter=5.4ft
Radius=diameter/2
=5.4ft/2
=2.7ft
π=3.14
Volume of a sphere=4/3πr^3
=4/3×3.14×2.7^3
=4/3×3.14×19.683
=4/3×61.80462
=247.21848/3
=82.40616
Approximately
82.4 ft^3
Answer:
1. y = 9280 - 20x
2. f(y) = 6.37y - 3
Step-by-step explanation:
1. The equation is given to be
Now, rearranging the function we can write
⇒ y = 9280 - 20x
Hence, this is the equation as a function of x. (Answer)
2. The given function is y - 6.37x = - 3
Therefore, we can write, y = 6.37x - 3
Hence, f(x) = 6.37x - 3
⇒ f(y) = 6.37y - 3.
Hence, option D is true. (Answer)
C obtuse scalene

Answer: 3 mph
Step-by-step explanation:
1. 1/2 mph for 1/2 an hour as they said, meaning that they would've walked for 3 miles kn an hour.
2. 4 and 1/2 miles.
3 + 1 2/4. = 4 1/2
3. 1 3/4 hours.
3 + 2.25 = 5.25
3 x .75 = 2.25
3 miles per hour.
