1.5 tons = 3000 pounds (because 1 ton is 2000 pounds)
Subtract 300 pounds, and you get 2700 pounds.
Answer:
Answer D: 12
Step-by-step explanation:
Three distinct denominators are shown here: 4, 3 and 2. The LCD is 12.
This corresponds to answer D.
We know that
volume of a sphere=(4/3)*pi*r³----> (r/3)*(4*pi*r²)
and
surface area of sphere=4*pi*r²
so
the volume of a sphere=(r/3)*surface area of sphere
therefore
if r=3
volume of a sphere=(3/3)*surface area of sphere
volume of a sphere=surface area of sphere
if r> 3
the term (r/3) is > 0
so
volume of a sphere > surface area of sphere
if r<3
the term (r/3) is < 0
so
volume of a sphere < surface area of sphere
examples
1) for radius r=3 units
volume of a sphere=(4/3)*pi*3³----> 113.04 unit³
surface area=4*pi*3²----> 113.04 units²
volume is equal to surface area
2) for radius r=10 units
volume of a sphere=(4/3)*pi*10³----> 4186.67 unit³
surface area=4*pi*10²----> 1256 units²
volume is > surface area
3) for radius r=2 units
volume of a sphere=(4/3)*pi*2³----> 33.49 unit³
surface area=4*pi*2²----> 50.24 units²
volume is < surface area
Answer:
1.
7 x 30 is equal to 3 tens-
9 x 200 is equal to 2 hundreds-
2 x 5,000 is equal to 5 thousands-
6 x 7,000 is equal to 7 thousands-
Step-by-step explanation:
30/10 = 3
200/100 = 2
5,000/1,000 = 5
7,000/1,000 = 7
I love you it's gonna be okay :)
