Sorry about my first answer then it would 20% because if you take 30 and divide 20% you'll get 6 so again sorry I was wrong 20 percent though is right.
Answer:
Step-by-step explanation:
<u>Area of circle:</u>
<u>Area of α degree sector:</u>
<u>The shaded area is:</u>
- S = π*10²×(72*2)/360 = 100π×144/360 = 40π
The solution to the problem is as follows:
<span>7(4)/4(4) = 28/16
28+16= 44
</span>
Therefore, the size of the graduating class would be 44 students in all.
I hope my answer has come to your help. God bless and have a nice day ahead!
Answer: C. y = 10x + 15
Step-by-step explanation:
He has already watched 15 movies so that's plus 15
And now he wants to watch 10 movies per week, we don't know how many weeks so that's '<em>x</em>' in this equation.
If he watches movies for <em>x </em>weeks that's 10 times <em>x </em>which is the 10x in the equation.
Hope that helped!
Answer:
BD is 3.75 units
Step-by-step explanation:
Given:
BA = 6 units
CA = 8 units
DC = 5 units
To Find:
BD = ?
Solution:
Triangle Angle Bisector Theorem.
An angle bisector of an angle of a triangle divides the opposite side in two segments that are proportional to the other two sides of the triangle.
I.e Here in Δ BAC,
AD is the Bisector of ∠ A
∴ 
Substituting th above given values in it we get
∴ 
∴ 
Therefore BD is 3.75 units
