Point b is on line ac so that ab : bc = 2 : 1. point d is on line ab so that ad : db = 3 : 2. find ad : dc

Firstly, we will draw figure

Let's assume

length of AC=x

we have

AB : BC = 2 : 1

so,

Point D is on line AB

and

AD : DB = 3 : 2

so, we get

now, we can locate these values

Firstly, we will find DC

DC=DB+BC

now, we can plug values

we have got

now, we can find ratio

now, we can simplify it

so,

AD:DC=2:3...........Answer

1gm = 1000mg so 0.1gm = 1000mg

first, convert the weight to kg

160lb * 1kg/2.2lb = 72.7kg

next, the dose

72.7kg * 100mg/kg = 7270mg

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
