Answer:
b. 3/1 c. -1/3
Step-by-step explanation:
When a line is parallel to another they don't intersect and instead go in the same direction. Therefore they have the same slope
b. 3/1
When a line is perpendicular it has to be the negative reciprocal. This means that it you have to flip the numbers in the fraction and make it negative (unless it is already negative, then it becomes positive)
c. -1/3
Answer: b<15
Step-by-step explanation: Divide each term by
20 and simplify inequality form: b<15
the salesperson earns a fixed cost of $ 30 plus 2/9th of his sales
we have to find how many sales he gets to earn $ 100 for one day
so lets say that the number of sales for the day - x sales
and he earns 2/9th of his sales
therefore amount he earns for x sales is -
this value plus his fixed earnings of $ 30 per day
so the amount he earns is 2x/9 + 30
this equals $ 100
so we can write the following equation
2x = 70 * 9
2x = 630
x = 315
so the amount of sales he earns for that day is 315 sales
Answer:
A) 8
B) See below
Step-by-step explanation:
A)
B) When dividing by a fraction, it is the same as multiplying by the inverse of that fraction. So instead of dividing by 2/3, you can multiply with 3/2.
I don’t know if I’m completely correct but the interior of a pentagon is 540 degrees so add all of them up. Then subtract 540- all of them added up and that should be the answer
