Answer:
6√5
Step-by-step explanation:
Y = 3/4x - 5/2....subtract 3/4x from both sides
-3/4x + y = -5/2 ....multiply everything by common denominator of 4
-3x + 4y = -10
Answer:
Option (A)
Step-by-step explanation:
Windmill is in the shape of a circle and each blade of the windmill is equally spaced.
There are 8 spaces in the windmill shown.
Therefore, angle between each blade =
Where n = number of blades
Angles between each blade =
= 45°
To reach the position of blade U by blade P will cover 5 angles between the blades.
Therefore, angle of rotation covered by P to reach U = 5×45° = 225°
Option (A) will be the correct option.
You can take out a 3x and get (3x)2x^4+3x^2-9
Answer:
55.55%= boys & 44.44% = girl
Step-by-step explanation:
1000/(1000+800)=1000/1800=.5555 or 55.55% are boys
800/(1000+800)=800/1800=.4444 or 44.44% are girls.
Therefore, 55,55% are boys and 44.44% are girls.
