Answer: y=-2/5x-3/5
Step-by-step explanation:
y=-2/5x+3
x=-2/5y+3
x(5y+3)=-2/5y+3×5y+3
x(5y+3)=-2
Devide by X on both sides
5y+3=-2/x
5y=-2/x-3
y=-2/5x-3/5
Answer:
3,4,55 by-step explanation:
Answer:
Step-by-step explanation:
There are 420 students.
41% are first year students.
41% = 41/100
420 * 41/100 = 172.4
What do you do about the 0.4? I would just round to the nearest whole number which is 172.
There are 420 - 172 = 248 who are not first year students.
One third of the box will be 3 inches long, so is equivalent to a 3-inch cube. It has a volume of
... (3 in)³ = 27 in³
The appropriate choice is ...
... D. 27 cu. in.
_____
Volume is found by multiplying length by width by height. When all are the same (3 in), the product is (3 in)·(3 in)·(3 in) = (3 in)³.
Answer:
The positive angle less than 360° that is coterminal with -215° has a measure of 145°.
Step-by-step explanation:
From Geometry, we know that angles form a family of coterminal angles as function of number of revolutions done on original angle. We can represent the set of all coterminal angles by means of the following expression:
, 
(1)
Where:
- Original angle, in sexagesimal degrees.
- Coterminal angle, in sexagesimal degrees.
- Coterminal angle index, no unit.
If we know that 
and 
, then the coterminal angle that is less than 360° is:
The positive angle less than 360° that is coterminal with -215° has a measure of 145°.
