Answer:
length = 4 width = 4 height = 10
Step-by-step explanation:
8x4x5 = 160
4x4x10 = 160
Answer:
n = 15
Step-by-step explanation:
A straight line equals 180 degrees
Angle SWT is congruent to angle XWV meaning:
SWT (55 degrees) = XWV (55 degrees)
Set up an equation:
3n + 80 + 55 = 180
Combine like terms
3n + 135 = 180
Subtract both sides by 135 to isolate variable n
3n = 45
Divide both sides by 3 to isolate variable n
n = 15
Answer:
Step-by-step explanation:
1. x^2 + 6x = 5
x^2 + 6x + 9 = 14
(x+3)^2 = 14
x = 
- 3
2. x^2 + 8x -4 = 0
x^2 + 8x = 4
x^2 + 8x + 16 = 20
(x+4)^2 = 20
x = 
- 4
<span>cost of producing x radios is c(x) = 400 + 20x - 0.2x
where:
x=number of units
thus the cost required to produce 30 units will be given by
c(30)=400+20(30)-0.2(30)
c(30)=400+600-6
c(30)=994
Answer: Marginal cost will be $994</span>
