Answer:
Perimeter = 4s
s = P/4
s = 48 in/4
s = 12 in
V = a^2h/3
h = 3V/a^2
h = 3(288 in^3)/ (12 in)^2
h = 864 in^3 / 144 in^2
h = 6 inches
Answer:
subtraction
Step-by-step explanation:
b= 40 - 5
40- 5 =35
b=40
Answer:
a) m =589.734kg
b) n = 8 people (rounded down)
Step-by-step explanation:
The first step is to calculate the maximum load after safety considerations (
Since we know that the maximum tension the cables can withstand is 19500N (or 19.5kN). To calculate (
we multiply this value by
(as per the given safety consideration.
Hence

a) Now to find the maximum load in kgs, we use the following formula

Where
= mass of elevator
= maximum load
= acceleration due to gravity
= maximum acceleration of elevator
Inputting the values and solving

Hence the maximum load is m =589.734kg
b) To find the number of people (n) we divide the value of m by 70kg
n = 589.734 / 70
n = 8.42 or 8 people
Step-by-step explanation:
A=P(1+R)
A/P=1+R
(A/P)-1=r
(3000000/20000)-1=r
149=r
