P = 2H + 2L
L = 6
P = 18
18 = 2H + 2*6
18 = 2H + 12
6 = 2H
H = 3 ft
Answer:
The family traveled at 45 miles per hour.
Step-by-step explanation:
To solve for the materials quantity variance, we have the formula below:
Materials Quantity Variance = (Actual Quantity Used * Standard Rate) - (Standard Quantity Allowed * Standard Rate)
The solution is shown below:
Materials Quantity Variance = ($9.20 - $9.00)*3400
Materials Quantity Variance = $680
The answer is $680.
5 or 6 years. subtract 1200 from 10000until you get 2800
The tree trunk is a cylinder so we apply that formula:
It is VCylinder = density x pi x radius x height
So the given in our problem is:
Density = 45 lb/ft^3 = 720.8 kg / m³
Radius = 3ft
Height = 10 ft
Insert variables that in our equation:
VCylinder = 720.8 kg / m³ * pi * 3ft² * 10 ft = 5771.26 kgs
