Answer:
The money he will save if he earns $120.00 is <u> $90.00</u>.
Step-by-step explanation:
Given:
In the figure is the ratio of the savings and the earnings.
Now, to find out that how much savings will be if Miguel earns $120.00.
We need to get the percentage of the ratio of the earning and saving.
So, according to the table:
If he earns $10.00 then he saves $7.50.
So, if Miguel earns $10.00 he save the 75% of it.
If he earns $50.00 then he saves $37.50.
As we calculate the percentage as the above process then the saving is 75% of the earning.
And, if he earns $150.00 and save $112.50 then it is also the 75% of the earning as mentioned above.
Now, to find the saving of the earning $120.00.
So, it will be 75% of the earning as we observe in the above case:
75% of $120.00
Therefore, the money he will save if he earns $120.00 is <u> $90.00</u>.
Answer:
A=152
K= -Ln(0.5)/14
Step-by-step explanation:
You can obtain two equations with the given information:
T(14 minutes) = 114◦C
T(28 minutes)=152◦C
Therefore, you have to replace t=14, T=114 and t=28, T=152 in the given equation:
Applying the following property of exponentials numbers in (II):
Therefore can be written as
Replacing (I) in the previous equation:
Solving for k:
Subtracting 190 both sides, dividing by -76:
Applying the base e logarithm both sides:
Ln(0.5)= -14k
Dividing by -14:
k= -Ln(0.5)/14
Replacing k in (I) and solving for A:
Dividing by 0.5
A=152
