Answer:
i can not see the picture
Step-by-step explanation:
i = (100m)/c
lowest i = 80, highest i = 120
c = 12
this will result in 2 equations, one will be the lowest (solving m when i = 80), and the highest (solving m when i = 120)
solve m when i = 80:
i = (100m)/c
80 = (100m)/12
80×12 = 100m
960 = 100m
960/100 = m
9.6 = m
solve m when i = 120:
i = (100m)/c
120 = (100m)/12
120×12 = 100m
1440 = 100m
1440/100 = m
14.4 = m
therefore,
The correct quotient is -3
The mistake CJ likely made is multiplying using the reciprocal of -3/4. The correct option is d. He multiplied using the reciprocal of -3/4
From the question,
We are to determine the correct quotient.
The given division operation to be carried out is -3/4 divided by 1/4
The correct quotient can be determined as shown below
Multiply by the reciprocal of
The reciprocal of is
Then, we get
This gives
= -3
The correct quotient is -3
The mistake CJ likely made is multiplying using the reciprocal of -3/4.
Hence, the correct quotient is -3
The mistake CJ likely made is He multiplied using the reciprocal of -3/4. The correct option is d. He multiplied using the reciprocal of -3/4

There are 5 20% in 100% ( 20 x 5 = 100)
So 10% of a number would be 12 x 5 = 60
Then there are 10 10% in 100% ( 10 x 10 = 100).
So if 10% = 60, then 100% = 60 x 10 = 600.
The starting value is 600
600 x 10% = 600 x 0.1 = 60
60 x 20% = 60 x 0.2 = 12
Now you have the starting value you can calculate the other answer:
600 x 20% = 600 x 0.20 = 120
120 x 10% = 120 x 0.10 = 12
The answer would be 12
