1 answer:
<h2>Answer:</h2>
The number of kilograms a 19 m beam can support is:
378.9474 kg
<h2>Step-by-step explanation:</h2>It is given that:
The weight W that a horizontal beam can support varies inversely as the length L of the beam.
Let k denote the constant.
This means that the weight W and Length L is related as:
Suppose that an 8 dash m beam can support 900 kg.
This means that L=8 and W=900
Then,
Now , we are asked to find the value of W when L= 19

Ok, a fun hack
if f⁻¹(a)=b then f(b)=a
so if f⁻¹(7)=b then f(b)=7
to find b, find x such that f(x)=7
7=0.5(3)^x
times both sides by 2 (or divide both sides by 0.5)
14=3^x
take log₃ of both sides

Answer:
Due to the location of the marker, it is closest to:
C.) 10/16 = 5/8 lb.
Each pound is divided into 16ths since 10 sixths are represented by the marker then the answer would be 10/16.
10 / 16 = 5 / 8
10 divided by 2 = 5
----------------------------
16 divided by 2 = 8
Therefore 10 / 16 = 5 / 8.
