So far, Phillip has completed 3/4 of his run. If he has run 9 miles, how far does he plan to run

Answers

Answer:

He has to run a total of 12 miles and has 3 more miles to run

Step-by-step explanation:

Well we know that 3/4 is 9 out of the total miles he is willing to run. We can divide 9 by 3 to get 1

Now we know 1/4 of his run is 3 miles

3*4= 12

He has to run a total of 12 miles and has 3 more miles to run

Answer:

He plans to run 12 miles

Step-by-step explanation:

He plans to run 12 miles because if he ran 9 miles so far and that is 3/4 of his way then you would do 3 divided by 9 to get 3.  Then you would add a 3 to nine because that 3 would be the last quarter t complete his run.

Answers

Answer:

B. y = -3x - 9

Step-by-step explanation:

Please let me know if you want me to add an explanation as to why this is the answer. I can definitely do that, I just wouldn’t want to write it if you don’t want me to :)

The equation perpendicular to the given equation is y=-3x-9. Therefore, option B is the correct answer.

Given that, the equation of the line is y+2 = 1/3 (x-5) and the coordinate point is (-4, 3).

Here, the slope is 1/3

The slope of a line perpendicular to given line is m1=-1/m2

So, the slope is m=-3

Substitute m=-3 and (x, y)=(-4, 3) in y=mx+c, we get

3=-3×(-4)+c

3=12+c

c=-9

So, the equation is y=-3x-9

Therefore, option B is the correct answer.

HELP!!! 25 POINTE AND BRAINLIEST!! a local cafe sells 7,200 cold beverages in the month of july. over the next six months, the number of cold beverages decreases at an average rate of 750 cups per month. During the same time frame, the number of hot beverages sold is represented by the equation y=900x + 3,300 where the number of hot beverages, y, is a function of x, the number of months after july.

A. what is the rate of change of cold beverages sold per month? hot beverages?

B. which rate of change is greater? what does it mean?

Answers

Answer: a. The rate of change of cold beverages: -750 cups/month

The rate of change of hot beverages: 900 cups/month

b. The rate of change of hot beverages is greater (900 > -750). It means that the number of hot beverages sold increases at a rate of 900 cups every month.

Step-by-step explanation:

a. The question says that "the number of cold beverages decreases at an average rate of 750 cups per month". This indicates that the rate of change of cold beverages is -750 cups/month. Why negative? Remember that it decreases, not increases.

Then let's look at the equation given for the sale of hot beverages:

y=900x + 3,300

The slope of the equation is 900, which is also the rate of change. So the rate of change of hot beverages is 900

The perimeter of a rectangular meadow is 1004 m. What
will be the sum of the length and breadth of the meadow ?​

Answers

Answer:

hope it works for u

Step-by-step explanation:

Given the length of the rectangle = l

the breadth  of the rectangle = b

perimeter of the rectangle = sum of length of all sides of the rectangle  

                                             = l+ b+ l+ b

                                             =2 l+2 b

                                             =2( l+ b)

∴ perimeter of the rectangle =2( l+ b)

as given perimeter = 1004 m

hence ,

2(l+ b)= 1004

(l+ b)=1004/2  = 502 m

l+ b=502 m
