Which of the following weights would you expect to be suitable for weighing on an ordinary bathroom scale?
a) 2500 μg
b) 5×10−4 kg
c) 4×106 cg
d) 5.5×108 dg
e) 2.0×107 mg

c) =40Kg

Step-by-step explanation:

To find the answer we have to put all the options in the same unit, so we are going to use Kg.

μ

Replacing the value of μ:

Observation: 1 g = 0.001 Kg, 1 g= Kg

This number is very small so it's no suitable for weighing on an ordinary bathroom scale.

This value is already in kilograms,

But it's small. It's not suitable for weighing on an ordinary bathroom scale.

Centigrams: cg=

Then,

This value it's suitable for weighing on an bathroom scale.

Decigrams: dg=

Then,

This value is too big for a bathroom scale. Usually the limit for an ordinary bathroom scale is between 140-150 Kgs.

Miligrams: mg=

Then,

This could be a right answer too but it all depends on the scale. There are some scales whose  minimum weight is 30Kg. So the right answer is c)

30

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
