Ashley is wrong. I have no clue what a placement chart is but I'll solve it anyway.
(5/10)x100 = (5x100)/10 = 500/10 = 50
First Step: What two multiples have perfects squares that equal 48 and 12? P.S They also need to have a common multiple so you can combine like terms in the end.
16*3=48
4*3=12
Second Step: Now use those multiples to split up your square roots so you will have perfect squares.
2√48 + 2√12=
2√16 ×√3 + 2√4×√3= Now Simplify!
2×4×√3 + 2×2×√3= Multiply!
8√3 + 4√3
Third Step: Now that they look alike you can just add them.
Answer: 12√3
Answer:
A=49.12
Step-by-step explanation:
A= bh/2 + πr²/2= 6*8/2 + 16π/2=49.12ft
Answer:
y=1.15x-12.41
44
Step-by-step explanation:
I needed this answer as well. But i got it off of delta math. So this is 100% Correct.
The length of the side BC is 6√3 inches
Step-by-step explanation:
Let us revise the sine rule
In Δ XYZ
- The side XY is opposite to angle Z
- The side YZ is opposite to angle X
- The side XZ is opposite to angle Y
- The sine rule is
In Δ ABC
∵ m∠A = 60°
∵ m∠C = 30°
∵ AB = 6 inches
- By using the sine rule
∵ AB is opposite to ∠C
∵ BC is opposite to ∠A
∵ 
∴ 
- By using cross multiplication
∴ BC × sin(30) = 6 × sin(60)
∵ sin(30) = 
and sin(60) = 
∴ BC = 6( )
∴ BC = 
- Multiply both sides by 2
∴ BC = 6√3
The length of the side BC is 6√3 inches
