Answer:
$42.50
Step-by-step explanation:
discount reduces the price of the good
discount value = 15% x 50 = 0.15 x 50 = 7.5
sales price = 50 - 7.5 = 42.50
For my answer, I got -47 1/2
A^2 + b^2 = c^2
a^2 + 9^2 = 18^2
a^2 + 81 = 324
a^2 = 243
a = 15.589 = 15.6 feet is the angle the ladder is at :)
Step 1: Line up the equations so that the variables are lined up vertically.
Step 2: Choose the easiest variable to eliminate and multiply both equations by different numbers so that the coefficients of that variable are the same.
Step 3: Subtract the two equations.
Step 4: Solve the one variable system.
Step 5: Put that value back into either equation to find the other equation.
Step 6: Reread the question and plug your answers back in to check.
Answer:
3600 pounds
Step-by-step explanation:
One cubic foot of a chemical weighs 60 pounds.
1 ft³ of chemical = 60 pounds
We need to find how many pounds in the container whose dimension 6 ft, 4 ft and 2.5 ft
l = 6 ft
b = 4 ft
h = 2.5 ft
Volume of box = lbh
= 6 x 4 x 2.5
= 60 ft³
As we are given
1 ft³ of chemical = 60 pounds
60 ft³ of chemical = 60 x 60 = 3600 pounds
