Who knows proportional relationships? and how to solve these both

Mathematics

ExtremeBDS [4]2 years ago

"Porportional Relationships" means that the rate in which it increases is the same.

For example: 1, 3, 5, 7, 9 is a porportional relationship, because it increases each time by (+2).

Now, look at the first one.

From y to x, y being 2, x being 10, you divided 5 from x to get 2. Next, you divided 6 from 30 to get 5. Because the number dividing is different, it is not proportional

NOT PROPORTIONAL

Look at the second one.

From y to x, y being 12, x being 10, you divided 1.2

Now, look at the next one. 30/25 = 1.2

Finally, the last one. 48/40 = 1.2

Because all of them are 1.2, the answer is proportional

PROPORTIONAL

Erin made a line plot of the amount of time she practiced shooting free throws each day in the past 10 days.
Airida [17]

Answer:

Data: for the 10 days of practice, we have:

0.5 hours 1 time.

0.75 hours 2 times

1 hour 3 times

1.25 hours 2 times

1.5 hours 1 time

2 hours 1 time.

A) the largest amount number of times that she practiced by the same amount of time is 3 (for the 1-hour practice)

The smallest is 1 ( for the 0.5h, 1.5h, and 2h practices)

the difference is 3 - 1 = 2.

B) the time that she practiced more times is 1 hour, she practiced that amount of time in 3 different days out of the 10 days.

C) the equation can be found by multiplying the number of hours by the number of times that she practiced that amount of time, and then adding all of them:

0.5h*1 + 0.75h*2 + 1h*3 + 1.25h*2 + 1.5h*1 + 2h*1  

D) the solution for the previous equation is 11 hours. Here the correct option is A.

A wire 18 cm long is cut into two pieces. The longer piece is 6 cm longer than the shorter piece. Find the length of the shorter
Yuliya22 [10]

Answer:

shorter piece = 6. longer piece = 12

Step-by-step explanation:

short piece = s

long piece = l

l+s= 18

l= 6+s , substitute

6+s+s = 18

6+2s= 18

2s= 18-6

2s= 12

s=12/2

s= 6= shorter piece

l= 6+s

l= 6+6= 12 = longer piece
