Sue ran the first 12 miles of the 24-mile Fun Run in 72 minutes. Her rate decreased by 2 miles per hour in the second half of th

densk [106]

Answer:

90 minutes or 1.30 hours

Step-by-step explanation:

In 72 minutes, Sue ran 12 miles per hour

In 1 minute, Sue ran 12/72 miles per hour

In 60 minutes, Sue ran (12/72)*60 miles per hour

= 10 miles per hour

Remaining miles after completing 12 miles in 72 minutes = (24-12) = 12 miles.

If the mileage decreases to 2 miles per hour, he will now run = (10 - 2) = 8 miles per hour.

Now,

1 hour = 60 minutes

Sue can run 8 miles in 60 minutes

Sue can run 1 miles in 60/8 minutes

Sue can run 12 miles in (60/8)*12 minutes

= 90 minutes or 1.30 hours

Which table shows a proportional relationship between x and y? Plz Help

Nastasia [14]

Answer:

The proportional table in the attached figure

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

Verify each table

Find the value of the constant of proportionality k for each ordered pair of a table.

$k=\frac{y}{x}$

If all the values of k are the same, then the table represent a proportional relationship between x and y

Table 1

For x=1, y=2 ----> $k=\frac{2}{1}=2$

For x=2, y=4 ----> $k=\frac{4}{2}=2$

For x=3, y=8 ----> $k=\frac{8}{3}=2.7$

The values of k are not equal

so

This table not represent a proportional relationship between x and y

Table 2

For x=0, y=4

The line not passes through the origin

so

This table not represent a proportional relationship between x and y

Table 3

For x=0, y=0 ----> is OK the line passes though the origin

For x=1, y=1 ----> $k=\frac{1}{1}=1$

For x=2, y=4 ----> $k=\frac{4}{2}=2$

The values of k are not equal

so

This table not represent a proportional relationship between x and y

Table 4

For x=1, y=4 ----> $k=\frac{4}{1}=4$

For x=2, y=8 ----> $k=\frac{8}{2}=4$

For x=3, y=12 ----> $k=\frac{12}{3}=4$

The values of k are the same

so

This table represent a proportional relationship between x and y

The World Issues club has decided to donate 60% of all their fundraising activities this year to Stephen Lewis Foundation. This

nika2105 [10]

Answer:

Step-by-step explanation:

a)/Let x represent the amount of money earned by the World Issues club for all their fundraising activities this year.

Let y represent the revenue generated for the foundation.

b) The World Issues club has decided to donate 60% of all their fundraising activities this year to Stephen Lewis Foundation. Therefore, an equation that will determine the amount of money the foundation will receive is

60/100 × x = y

0.6x = y
