Answer:
59%
Step-by-step explanation:
There are 7 days out of 14 that are 20 or more
That would be 59%
Answer:
9 bags
Step-by-step explanation:
Weight each bag should be = 3/4 pound (0.75 pound)
Total weight of sunflower seeds available = 6.5 pounds
Number of packages made = 6.5/ 3/4
= 8.66666666667
= So 9 bags at the most
If you write 8, then you wouldn't be able to fit the other 0.5 pound and if you put 9, well you will have enough more space to put 6.5 pounds.
Hope this helps!!

<h3>What is a system of linear equations?</h3>
- A system of linear equations is a set of two or more linear equations.
- Linear equations refer to the equations that involve two or more variables in the form of "ax + b".
Now,
Given:
- Total number of questions = 200
- Marks for correct answer = 4
- Marks for incorrect answer = -1
- Total marks = 250
To find : Number of correct answers = ?
Finding:
Now, assuming that the student attempted and answered all the questions,
- Let the number of questions correctly answered be x and incorrectly answered be y.
Then,
- x + y = 200 (For number of questions) (eqn 1)
- and 4x - y = 250 (For the marks scored) (eqn 2)
Solving the system of linear equations:
For eqn 2, we get that y = 4x - 250
Substituting in eqn 1, we get:
=> x + 4x - 250 = 200
=> 5x = 250 + 200 = 450
=> x = 90
That is, the number of questions answered correctly = 90, the incorrect answers = 200 - 90 = 110.
