Answer:
28k
Step-by-step explanation:
The perimeter is the sum of the four equal-length sides:
P = 7k +7k +7k +7k
P = k(7 +7 +7 +7)
P = 28k . . . . perimeter of the rhombus
__
Of course, multiplication was invented to make repeated addition easier. Here, the perimeter is 4(7k) = 28k, no like terms to combine.

Answer:
Z value for the first pump = -0.68
Z value for the second pump = 0.45
Step-by-step explanation:
Data provided in the question:
Mean labor cost to repair a heat pump = $90
Standard deviation = $22
Labor cost for the first, X₁ = $75
Labor cost for the Second, X₂ = $100
Now,
Z value for the first pump = [X₁ - Mean] ÷ Standard deviation
thus,
Z value for the first pump = [ $75 - $90] ÷ $22
= - 0.68
Z value for the second pump = [X₁ - Mean] ÷ Standard deviation
thus,
Z value for the second pump = [ $100 - $90] ÷ $22
= 0.45
<em>11 2/5 mm³</em>
- Step-by-step explanation:
<em>Hi there ! </em>
<em />
<em>3 4/5mm³ = (3×5 + 4)/5 = (15 + 4)/5 = 19/5 mm³</em>
<em />
<em>19/5 mm³ ............. 1/3 box</em>
<em>x mm³ .......................1 box</em>
<em>x = 19/5×1 : 1/3</em>
<em>= 19/5 × 3/1</em>
<em>= 19×3/5</em>
<em>= 57/5</em>
<em>= 11 2/5 mm³</em>
