Answer:
y=9
Step-by-step explanation:
-2[(4y+1)-(2y-2)]=6(7-y)-6
-2[4y+1-2y-2]=6(7-y)-6
-2[2y-1]=6(7-y)-6
-2y+2=6(7-y)-6
-2y+2=42-6y-6
Add 6y to both sides
4y+2=42-6
4y+2=38
Subtract 2 from both sides
4y=36
Divide both sides by 4
y=9
Answer:
percentage profit = 150%
Step-by-step explanation:
percentage profit = sp - cp/cp * 100
sp is the selling price = 60000
cp is the cost price = 24000
percentage profit = 60000-24000/24000 * 100
percentage profit = 36000/24000 * 100
percentage profit = 36000/240
percentage profit = 150%
Answer:
8 counselors and 12 aids
Step-by-step explanation:
minimum number of staff to run camp = 20
Ratio of counselors to aids to work together = 2:3
To get the multiply factor = 20 / (2 counselors + 3 aids) = 20 / 5 =4
minimum number of counselors needed = 4 x 2 = 8 counselors
minimum number of aids needed = 4 x 3 = 12 aids

Answer:
31.41 ft²
Step-by-step explanation:
Heron's formula is useful when you have the three side lengths.
A = √(s(s -a)(s -b)(s -c)) . . . . sides are a, b, c and s = (a+b+c)/2
Using the given side lengths, we have ...
s = (8 +8.4 +13.5)/2 = 29.9/2 = 14.95
A = √(14.95(14.95 -8)(14.95 -8.4)(14.95 -13.5)) = √(14.95×6.95×6.55×1.45)
A = √986.81399375 ≈ 31.41 . . . . square feet
