Rachel is planning to run an average of 6.4 miles over three consecutive days. On the first
day, she ran 6.6 miles, and on the second day, she ran 6.5 miles. What is the maximum
number of miles Rachel can run on the third day without going over the planned average of
6.4 miles per day?
The maximum number of miles Rachel can run on the third day without going over the planned average of 6.4 miles per day is 6.1 miles.
Maximum number of miles:Let x represent the maximum number of miles
Formulate
6.6+6.5+x÷3=6.4
Hence:
6.6+6.5=6.4×3
13.1+x=19.2
x=19.2-13.1
x=6.1 miles
Inconclusion the maximum number of miles Rachel can run on the third day without going over the planned average of 6.4 miles per day is 6.1 miles.

What is the PERCENT DECREASE: 1) PRINCETON: December - 50 January - 40 2) WORCESTER: December - 256 January - 197 3) CHICAGO: December - 7050 January - 6708
Answer: See explanation
Step-by-step explanation:
PRINCETON:
December - 50
January - 40
Decrease = 50 - 40 = 10
Percentage Decrease = Decrease/Original value × 100
= 10/50 × 100
= 20%
2) WORCESTER:
December - 256
January - 197
Decrease = 256 - 197 = 59
Percentage Decrease = Decrease/Original value × 100
= 59/256 × 100
= 23.05%
3) CHICAGO:
December - 7050
January - 6708
Decrease = 7050 - 6708 = 342
Percentage Decrease = Decrease/Original value × 100
= 342/7050 × 100
= 4.85%

The product of two consecutive integers is 72. Write a quadratic equation to find the integers, and then solve it.
Answer:
9 x 8
Step-by-step explanation:
Answer:
ok so basically what you do is since you know they are consecutive numbers, one is x and the other is x+1. Now when you multiply x and x+1 you get 72 , so this basically turns into a quadratic where x(x+1)=72. Thus,X^2+x=72. subtract 72 from both sides- x^2+x-72=0. Then you can solve for x using the quadratic formula or some other way and you get x to be 8 or -9. OH WAIT THERE IS ANOTHER SOLUTION IT IS -9 AND -8. . Anyway yea hoped this helped.

Romantic writers rejected the logical style of writers from the age of reason and instead focused on individual experiences, thoughts, and emotions. Romantic literature used lofty, expressive language to highlight a particular mood and message. What do you think these techniques offered to romantic writers that previous styles did not? Consider the romantic literature you have read. Do you think these techniques and styles were effective for the themes and subjects being addressed? Why or why not?
Answer:
Step-by-step explanation:
Romantic writers have the advantage of writing what they feel not just what they made up. Romantic writers can make a book sad, scary, and happy. Whereas fictional books almost always end up perfect for the main character. I do think that the techniques and styles were effective for the themes and subjects being addressed because they flow into the subject. Using an absolute sob story for a romantic book could be passed off as a hit if you use the right techniques. So, yes. I do think that the techniques and styles were effective for the themes and subjects being addressed.

What is the image of the point (9, – 7) after a rotation of 270° counterclockwise
about the origin?
Answer:
The image if the point is (-7, -9)
Step-by-step explanation:
If The point (x, y) rotated about the origin by angle 90° counterclockwise, then its image is (-y, x)If the point (x, y) rotated about the origin by angle 180° counterclockwise, then its image is (-x, -y)If the point (x, y) rotated about the origin by angle 270° counterclockwise, then its image is (y, -x)∵ The given point is (9, -7)
∴ x = 9 and y = -7
∵ The given point is rotated 270° counterclockwise about the origin
→ By using the third rule above
∴ The image of the point is (y, -x)
→ That mean change the sign of x-coordinate, then switch them
∵ x = 9 and y = -7
∴ The image if the point is (-7, -9)

A cylinder has a diameter of 7 and height of 10.4 . What is its total surface area to two decimal places
Answer:
305.68
Step-by-step explanation:
π = 3.14(aka pi)
d=diameter
h=height
^=exponent
The formula for doing this types of problem is 2π d/2h + 2π(d/2)^2. So all you do is fill in the diameter and height of the variable.
2π 7/2(10.4) + 2π(7/2)^2=305.68

Answer:
3
Step-by-step explanation:
If you substitute the values x = 0 and y = −5 into the second equation, you get a false statement: 2(−5) − 10 = 2(0). To solve this system, try rewriting the first equation as x = 2y − 8. Then substitute 2y − 8 in for x in the second equation, and solve for y. The correct answer is x = −2, y = 3.
