Answer:
Step-by-step explanation:
∠ABC = 1/2 ∠AOC
since we know ABC = 30° we can solve for AOC with a bit of Algebra
30 = 1/2 AOC
60 ° = AOC
:) does it make sense?
the formula about is for inscribed angles , that is an angle that touches the outside of the circle and then goes through the other side. :) Like ∠ABC
Answer:
x =2/3
Step-by-step explanation:
4^3x=4^2
Since the bases are the same, the exponents are the same
3x =2
Divide each side by 3
3x/3 = 2/3
x = 2/3
Answer:
( x - 3i ) ( x + 3i )
= x^2 + 3xi - 3xi - 9i^2
= x^2 - 9 (-1)
= x^2 + 9
(x^2 + 9 ) ( x + 5 )
Now the left hand side is equal to the right hand side.
Good luck!
Step-by-step explanation:
Total students: 80
We know that:
-business has 14 students
-education has 6 students
-undecided has x students
We need to find out x! So we can add 14 and 6 up and subtract it by 80 to figure out the amount of undecided students there are.
80-(14+6)=60
To find out the percentage, we divide the number of undecided students by the number of total students, and multiply it by 100.
60/80=30/40=0.75=0.75*100=75%
75% of the class is undecided for a major
The slope (gradient) is 1/2 and the intercept is 5. The formula is y=mx+c , where m is the slope and c is the gradient.
