A group of hikers tracked how long it took to hike a 20-mile trail. They hiked 3.75 miles in 3 hours, 7.5 miles in 6 hours, and 12 miles in 8 hours. Determine if the relationship between the hikers' distance and time is proportional. Yes, it is proportional because the ratios for miles per hour are all equivalent
Answers
Answer: the answer is d
Step-by-step explanation:
3.75 mi in 3 hours
you need to do 3.75÷3=
and you get 1.25 mi an hour
now you need to do the next one
it is 7.5 mi in 6 hours
so, you're going to do 7.5÷6=
and we get 1.25 mi an hour
now let's do the last one
12 mi in 8 hours
you're going to do 12÷9=
and you get 1.5 mi in an hour
so, the 3 hours and 6 hours are proportional
therefore, the answer is d) No, it is not proportional because 7.5 miles in 6 hours is not equivalent to 12 miles in 8 hours.

If 10 workers take eight hours to sew a stores order of pants, then how long would 15 workers take to sew the stores order of pants? Assume all workers work at the same steady rate and all the pants are the same. Part A.) Is the proportion 8hours/10 workers = Xhours/15 workers appropriate for solving the sewing problem why or why not? Part B.) explain how to reason about multiplication and division with quantities to solve the sewing problem
Answers
According to the given data we have the following proportion:
8hours/10 workers = Xhours/15 workers
A) The above proportion is not appropiate for solving the problem.
Since, the relationship between the number of workers and the time taken for sewing is an inverse relation:
The above proportion is just a direcly proportional relation.
B). As I stated above the relationship between the number of workers and the time taken for sewing is an inverse relation, hence, if the number of workers doubles then the number of time taken reduces to half.
So, since 15=10*15/10
therefore, time taken for 15 workers to sew pants is:
8/ 15/10 = 8* 10/15
=5 1/3 hours.
The time taken for 15 workers to sew pants is 5 1/3 hours.

Out of the two projects A and B, project B is giving higher rate of return on the investment so maximum investment needs to be done on the project B
Hence in project B total percentage of investment will be [tex]40%[/tex]% which is also given it needs not to exceed more than [tex]40[/tex]%

what is an equation in point-slope form of the line that passes through(-7,1)and(-3,9)
Answers
y-y1=m(x-x1)
To find the slope we can use the formula:
m=y2-y1/x2-x1
We can then insert our values given in the question:
(-7,1)=(x1,y1) and (-3,9)=(x2,y2)
Inserted into the equation becomes:
m = 9-1/-3-(-7)
m = 2
Therefore, our slope equals 2 and we can find the rest of the equation using the aforementioned formula of:
y-y1=m(x-x1)
Insert our values:
y-1 = 2(x-(-7))
y-1 = 2(x+7) <— (negatives make a positive)
We can then multiply what’s inside the bracket by 2:
y-1 = 2x+14
And then to get y alone on the left side we will add 1 to both sides leaving us with:
y=2x+15
Therefore, y=2x+15 is your answer.

To match the correct features with its interpretation is as follows: Time (hours) = 0,2,4,6 is to 0, 25, 50, 75 (kilometers).
What is distance?Distance is defined as the area covered by a moving object without the influence of direction. The distance of an object is measured in kilometers.
The kilometers that are covered from finish line= (y) 75 50 25 0
The time used to cover the distance= (x)0 2 4 6
Therefore to arrange the features where the distance is away from the finish line;
x= 0 , 2 , 4, 6

234x
The coordinates are J'(_,_)K’(_,_)and L’(_,_)
Answers
Answer:
J': (3, 6)
K': (3, 4)
L': (0, 4)
Step-by-step explanation:
When we translate a point 4 units right, the x-coordinate of the point increases by 4 units, the y-coordinate remains the same
When a point is translated 3 units down, the y coordinate increases by 3 units, the x-coordinate remains the same
When you translate by 4 units right and 3 units down both x and y coordinates increase by 4 and 3 respectively
So when we apply this translation to the triangle, every point on that triangle, (x, y) changes to (x + 4, y + 3)
If we take the vertices of the triangle we see that the 3 vertices are
J(-1, 3) K(-1, 1) and L(-4, 1)
After applying the translation:
J(-1, 3) ==> J'(-1 + 4, 3 + 3) ==> J'(3, 6)
K(-1, 1) ==> K'(-1 + 4, 1 + 3) ==> K'(3, 4)
L(-4, 1) ==> L'(-4 + 4, 1 + 3) ==> L'(0, 4)
