Step-by-step explanation:
An arithmetic sequence is given by relation as follows :

For the first term, put n = 1. So,

For fourth term, put n = 4. So,

For tenth term, put n = 10. So,

Hence, the correct option is (C).
Answer:
C. 7h + 50 > 99
Step-by-step explanation:
She earns <u>more</u> than $99, so you know that the sign will be > (more than).
h is the number of hours, so to find how much she earns for working h hours at $7/hour, you multiply h by 7 --- 7h
She also earns an additional $50, which will be +50.
Therefore, the equation is: 7h + 50 > 99
Hope this helps :D
Answer:
You need to add more context to the question. I cannot answer it without knowing what "These scales" are.
Answer:
option c) x₁₁ + x₁₂ = 8000
Step-by-step explanation:
Given:
xij = gallons of component i used in gasoline j
gallons of component 1 available = 8,000
demand gasoline types 1 = 11,000
demand gasoline types 2 = 14,000
Here, we have only component 1 available i.e i = 1 only
( therefore, all the options containing i = 2 gets eliminated )
thus,
component 1 will fulfill the demand of gasoline types 1 and 2 i.e j = 1 and 2
hence,
the equation satisfying the above conditions comes out as:
x₁₁ + x₁₂ = 8000
that means gallons of component 1 used in gasoline 1 and 2 and the total equals to the gallons of component 1 available i.e 8000
