Answer: Third option.
Step-by-step explanation:
By definition, the slope of a line can be calculated with the following formula:
Since you need to solve for 
to find an equivalent expression, you can apply these steps:
1. You must multiply both sides of the equation by 
:
2. Finally, you must add 
to both sides of the equation:
It is the first one on the left ( 4 divided by 7)
Answer:
A) Total weekly salary = $1000 + ( 0.05 × s )
B) Yes this is a function
C) This is a function because the weekly salary is dependent on the number of sales 's'. Hence, total weekly salary is a function of sales.
D) Domain will be [ 0, ∞ ]
Step-by-step explanation:
Given :
Weekly salary = $1000
Commission = 5% of all her sales
Let the number of sales be 's'
thus,
A) Total weekly salary = $1000 + ( 0.05 × s )
B) Yes this is a function
C) This is a function because the weekly salary is dependent on the number of sales 's'. Hence, total weekly salary is a function of sales.
D) The domain here will be all the possible values of sales i.e 's'
Hence,
sales will always be positive
thus,
domain will be [ 0, ∞ ]
To fill:
6 hours = 1 tank
1 hour = 1/6 tank
To drain:
It takes 4 times as long, therefore 4 x 6 = 24
24 hours = 1 tank
1hour = 1/24 tank
If both pipes are open
1 hour = 1/6 - 1/24 = 1/8 tank
1/8 tank = 1 hour
8/8 tank = 1 x 8 hour
1full tank = 8 hours
Answer:
21/100
Step-by-step explanation:
Letters: ABCDEFGHIJ 10 letters
Vowels: AEI 3
P (vowel)= vowels/ total = 3/10
No replacement ( assume the letter taken was a
Letters: BCDEFGHIJ 9 letters
Consonants : BCDFGHJ 7 letters
P(constant) = 7/10
P(vowel, no replacement, consonant) =P (vowel)*P(constant)
=3/10*7/10
=21/100
