Answer:
400milliliters
Step-by-step explanation:
Let x=ml of 30% solution B used in resulting mixture.
800+x=ml of resulting 30% solution
40%(800)+10%x=30%(800+x)
Then we can simplify the expression
0.4(800)+0.10x= 0.30(800+x)
320+0.10x=240+0.30x
80=0.20x
x= 400milliliters
Therefore, 400milliliters of 10% solution B used in resulting mixture.
Answer:
C
Step-by-step explanation:
The arc length is calculated as
arc = circumference of circle × fraction of circle
= 2πr × 
= 2π × 18 × 
= 36π × ( cancel 36 and 24 by 12 )
= 3π × 
= 
→ C
Answer:
288
Step-by-step explanation:
24 is a multiple of 12, and 36 is a multiple of 12, so the LCM of 24, 32, and 36 will also be the LCM for 12 and 16.
24 = 2^2 * 3
32 = 2^5
36 = 2^2 * 3^2
LCM = 2^5 * 3^2
LCM = 288
