Step-by-step explanation:
If the test has 30 questions each worth 2 points, then the test is worth 60 points. [30 × 2]
Seema got 12 answers correct. If each is worth 2 points, then her 12 correct answers are worth 24 points. [12×2]
Her total score is 24/60.
1. y = -⅔x + 490
2. I would start with the y-intercept(490) on the graph. Then from that point, I would use rise/run to find the next point: I would go down two points (because the slope is negative), and run three points to the right.
3. f(x) = -⅔ + 490. The graph represents the total profits of last month.
4. View file below.
5. The graphs of these functions are similar in the fact that they are parallel to each other, therefore having the same slope.Both lines are also negative. They are different in that they do not have the same y-intercept or x-intercept.
Answer:
Total distance:
- d=11/15 miles or 0.73 miles
Step-by-step explanation:
- Alison walks 2/5 miles from her house to the mailbox.
- Then she walks 1/3 mile to the bus stop.
Thus, the total distance can be calculated by adding the miles
i.e.

LCM of 5,3 is 15



miles
Thus,
Total distance:
- d=11/15 miles or 0.73 miles
Answer:
A. He will have to work 40 hours to buy the headphones
B. 1200 ≤ 10.25x ≤ 2000 where x is # of hrs worked
He can work anywhere between 118 and 196 hours.
Step-by-step explanation:
A. Divide 399.95 by 10.25 to get 39.01 hours. But since you cant work 0.01 of an hour, you have to round up to the next hour
B. You want to make more than or equal to 1200, so put that in the inequality. You want to make less or equal to 2000, so you put that in the inequality. In the middle, you put 10.25 an hour multiplied by the number of hours, which is a variable.
To solve, I made 10.25x = 1200, and x equaled 117.07, which rounds up to 118 hours because you cant work a 0.07 of an hour. 118 hours is the low number of the spectrum.
To solve for the highest number on the spectrum, you do 10.25x = 2000, and x equals 195.12, but since you cant work 0.12 of an hour, it rounds up to 196 hours.
