Answer:
The rise is the vertical change between two points on a line, the run is the horizontal change.
X = 12 , just solved it right now :)
48/5 or 9 3/5
12.8/1 x 3/4 = 38.4/4
Or multiply 12.8/1 by 10 ==> 128/10
128/10 x 3/4 = 384/40
Hope this helps!
Answer:
64,000 oz
Step-by-step explanation:
A demolition (wrecking) ball is a relatively large dense mass, often spherical, typically swung from a crane, used to demolish buildings or other structures.
We assume you want to convert from a US short ton (2000 pounds) to Avoirdupois ounces (16 ounces per pound).
Then your ball's weight is ...
(2 tons)(2000 lb/ton)(16 oz/lb) = 64,000 oz
Answer:
Step-by-step explanation:
x² + y² + 42x + 38y - 47 = 0
Put the equation into standard (center-radius) form:
regroup terms
(x²+42x) + (y²+38y) = 47
complete the squares:
(x²+42x+21²) + (y²+38y+19²) = 47 + 21² + 19²
(x+21)² + (y+19)² = 849
center at (-21,-19)
radius = √849 units
The general form of the equation for a circle with radius √849 units is:
(x-h)² + (y-k)² = 849
where the (h,k) is the center.
