Step-by-step explanation:
7300-5500=1800 needs to come from salespeople. To make at least 7300, the salespeople need to make at least 1800, which means:
300 x number of people >= 1800
Number of people >= 6
C is correct
Answer:
Step-by-step explanation:
PEMDAS stand for Parentheses, Exponent, Multiplication, Division, Addition, and Subtraction.
3(x+5)
In this expression, we cannot perform any operation within the parentheses so we move to the next operation in the expression which is multiplication.
3(x+5)
becomes:
3x + 3(5)
3x + 15
We need to look for the value of x.
3x + 15 = 0
3x = -15
3x/3 = -15/3
x = -5
We need to substitute x by its value.
3(x + 5)
3(-5 + 5)
we can perform the P in PEMDAS
3(0) = 0
multiply.
3(0) = 0
0 = 0
Rule of zero. any number multiplied by zero is equal to zero.
Answer:
198 ft ^ 2
Step-by-step explanation:
The figure is divided into two, a rectangular prism and a pyramid.
The formula for the surface area for the rectangular prism is:
A1 = 2ab + 2bc + 2ac
we know that the sides are a = 4.5, b = 4.5 and c = 6, replacing:
2 * 4.5 * 4.5 + 2 * 4.5 * 6 + 2 * 4.5 * 6 = 148.5 ft ^ 2
Now for the pyramid, the surface area is:
A2 = Ab + 1/2 * p * s
The base area is, since it is a square:
Ab = 4.5 ^ 2
Ab = 20.25 ft ^ 2
Now the perimeter, being a square, is one side times 4:
p = 4.5 * 4
p = 18 ft
and the value for "s" is shown in the figure and is 3.3 ft, replacing:
A2 = 20.25 + 1/2 * 18 * 3.3
A2 = 49.95 ft ^ 2
Now the total area is:
At = A1 + A2 =
At = 148.5 + 49.95
At = 198.45 ft ^ 2
Therefore the surface area of the figure is 198 ft ^ 2
