Answer:
B
Step-by-step explanation:
Sin 45 = y/(11√6)
1/√2 = y/(11√6)
y= (11√6)/√2
y= 11√3
tan 60 = x/y
√3 = x/y
x = y√3
= (11√3)√3
= 11(3)
= 33
Let 'x' represent the amount of 50% mixture used, then '20-x' represents the amount of 10% mixture used
0.25(20) = 0.50x + 0.10(20-x)
solving for 'x' we have x=7.5
20-7.5 = 12.5
7.5 pounds of 50% mixture should be combined with 12.5 pounds of 10% mixture
Answer:
3.2
Step-by-step explanation:
First, evalue what's inside of the absolute value:
3.1 + (-6.3) = -3.2
Now, since absolute value means the distance from the number to 0, the absolute value of -3.2 is the negation of -3.2:
|-3.2| = 3.2
