Answer:
No. The value for b is incorrect (apex)
You divide 690 by 100 which is 6.9
Therefore, one 50cent coin is 6.9g
Answer:
6
Step-by-step explanation:
-X+11=-2X-7
11=3X-7
18=3X
18/3= 6
Answer:
Step-by-step explanation:
finding PR ( public relations :D , not that PR , the PR on this triangle thingy )
use law of cosines, again
c=sq rt [ a^2+b^2﹣2*a*b*cos(C) ]
where
c=PR
a= 9
b = 22
C = the angle of Q or 180 = 97+24+Q so Q = 180-97-24 = 59°
they tried to trick us.. by not giving us the angle C for the above cosine formula , but we figured out their diabolical plan :D yay super hero math
then
PR = sq rt [ 9^2 + 22^2 - 2*9*22*cos(59) ]
PR = sq rt [ 81 + 484 -203.9550777 ]
( notice that now it is a subtraction sign instead of a plus sign, this time? )
PR = sq rt [361.0449 ]
PR = 19.0011
to the nearest 10th
19.0 :)
Answer: x=3, x=1
Step-by-step explanation:
To find the zeros, you would set the equation to 0. Then, you would factor.
y=x²-4x+3
0=x²-4x+3
0=(x-3)(x-1)
Now that we have factored our equation, we will find the zeros by setting each factor equal to 0.
x-3=0 x-1=0
x=3 x=1
