Too much sand.
Volume is the amount of space something takes up. The formula for volume is v=length x width x height.
The volume of the sandbox is 36 ft^3, because 5x6x1.2 = 36. This means the box takes up 36 cubic feet of space.
If the customer bought 40 cubic feet of sand, than they bought to much because 40 > 36. The amount of sand she got is greater than the volume of the box, so it won’t all fit.
Using linear combination method to solve the system of equations 3x - 8y = 7 and x + 2y = -7 is (x, y) = (-3, -2)
<h3><u>
Solution:</u></h3>
Given that, a system of equations are:
3x – 8y = 7 ⇒ (1) and x + 2y = - 7 ⇒ (2)
We have to solve the system of equations using linear combination method and find their solution.
Linear combination is the process of adding two algebraic equations so that one of the variables is eliminated. Addition or subtraction can be used to perform a linear combination.
Now, let us multiply equation (2) with 4 so that y coefficients will be equal numerically.
4x + 8y = -28 ⇒ (3)
Now, add (1) and (3)
3x – 8y = 7
4x + 8y = - 28
----------------
7x + 0 = - 21
7x = -21
x = - 3
Now, substitute "x" value in (2)
(2) ⇒ -3 + 2y = - 7
2y = 3 – 7
2y = - 4
y = -2
Hence, the solution for the given two system of equations is (-3, -2)
3 hours. I think. X represents the # of hours and they equal the same after exactly 3 hours.
You would use, Order of Operations, A.K.A PEMDAS.
Parenthesis, Exponets, Multiplication, Division, Addition, Subtraction
Follow that order and you do the work yourself, you would never learn by asking other's for the answer. >:)

Answer:
<h3>$189,292.92</h3>
Step-by-step explanation:
Using the compound interest formula to get the equivalent amount after 5 years;
A = P(1+r/n)^nt
P is the principal = 120,000
r is the rate = 10% = 0.1
t is the time = 5 years
n is the time of compounding = 1/2 = 0.5(semi annual interest)
Substitute into the formula;
A = 120,000(1+0.1/0.5)^(5)(0.5)
A = 120,000(1+0.2)^2.5
A = 120,000(1.2)^2.5
A = 120,000(1.5774)
A = 189,292.92
Hence the company issue is $189,292.92
