Answer:
Porter is inches taller than Henry.
Porter is times taller than henry.
Step-by-step explanation:
The difference in height can be found using subtraction.
Since Porter is taller than Henry, we'll subtract away Henry's height from Porter's height. This will leave us with only the difference between the heights.
n = Porter's height
m = Henry's height
Difference in height is thus:
Answer: Porter is inches taller than Henry.
To find out how many times taller Porter is than Henry, we can use division.
An example: if Porter was 200cm, and Henry was 100cm, Porter is obviously 2 times as tall.
If we divide Porter's height by Henry's height...
..we'll get 2. This is because Henry's height "fits in twice" in Porter's height. 100 fits twice in 200.
Using our values, n and m, we'll divide n by m.
Answer: Porter is times taller than henry.
Answer:
Her expenses are $25 per week.
Step-by-step explanation:
Given :Jessica earns a commission on each sale but has to pay for her own expenses.
She writes the equation of the function like this: , where x is the number of doors she knocks on during the week and E(x) is her earnings for the week in dollars.
To Find: Which of the following are reasonable interpretations of the y-intercept of Jessica's function?
Solution:
x is the number of doors she knocks on during the week
E(x) is her earnings for the week in dollars.
Calculate y intercept
Substitute x = 0
Since E(x) is her total earning after clearing the payment of all her expenses.
So, 25 is her expenses per week.
Since we are given that she need to pay her expenses .
So, if there is no sale , still she need to pay expenses.
Thus the reasonable interpretations of the y-intercept of Jessica's function is Her expenses are $25 per week.
