Answer:
circle b and it is bigger by 1 centimeter
Step-by-step explanation:
since circle b has a radius of 5 and radius is have of the diameter you have to do 5+5 to get the diameter when you do that you get 10 and then you have to subtract circle a diameter which is 9 from circle b diameter which is 10 so 10-9 is 1
Answer:
2 and 3 are complimentary, and 2 plus 3 is 90 degrees. Therefore 90 minus angle 2 is angle 3.
Answer:
(3a³-5b³)+ (-2)a³ +6b³=(a³+b³)
Step-by-step explanation:
First, lets remove the brackets. There is no "-" before the brackets, so we can just remove them at all.
3a³-5b³+ ...a³ +...b³=a³+b³
Now we can joint similar monoms (with variable a) ( and with variable b) in the left side of equation
3a³+...a³ -5b³ +...b³=a³+b³
Now we can notice that 3a³+...a³=a³ (1) and
-5b³ +...b³=b³ (2)
Lets find deduct 3a³ from both sides of (1)
...a³= a³-3a³
...a³= -2a³ So instead ... we have to type -2 (-2 is negative sowe type -2 in brackets).
Similarly lets add 5b³ to both sides of (2)
-5b³ +...b³=b³
-5b³ +5b³ +...b³=b³+5b³
...b³=6b³ So instead ... we have to type 6.
Answer:
B. sin(5pi/4)= -(sqr2/2)
Step-by-step explanation:
Answer:
Step-by-step explanation:
hello : -6x+4y=-4....(*)
-6x+2y= 4...(**)
by (*) : -6x= -4y-4
by(**) : -6x = -2y+4
so : -4y-4=-2y+4
-2y = 8
y=-4
put this value in (*) : -6x+4(-4)= - 4
-6x=16-4=12
x=-2
