Explanation:
Since we have given that
Speed at which Eugene walked all the way to school = 3 mph
After realizing that she forgot her math book, she ran back
Speed at which Eugene walked back to her house = 7 mph
Let the distance between her house and her school be x
According to question,

Hence,

When the last child has finished his or her schooling and is no longer dependent on the parents, the Echo stage begins. This is the pre-retirement or "empty nest" stage. For those individuals without children, the Echo stage begins about 10 years before retirement.
A quart is equal to 4 cups.
A pint is equal to 2 cups.
Therefore a pint is half the size of a quart.
2 pints=1quart
$116.02 interest will be earned in 9 months
Step-by-step explanation:
The formula for simple interest is given by:

Here
P is the initial amount
r is the interest
t is the time measured in years
Given
P = $2475
r = 6.25% = 
t = 9 months
Converting time into year by dividing by 12

Putting the values in the formula

Rounding off to nearest hundredth
I = $116.02
Hence,
$116.02 interest will be earned in 9 months

Answer:
y= 10/3 x -18
Step-by-step explanation:
Perpendicular lines meet the following condition:
m2*m1=-1 (1)
The product of their slope is -1.
From the equation of the first line we can obtain the first slope.
y=-0.3x+6 -> m1=-0.3
Hence, the slope of our desired line is obtained from equation (1).
m2=10/3.
Remember, the equation of a line is given by:
y=mx+b
Now, we need to find the term 'b' and we will do that by evaluating the point (3,-8).
-8=10/3 * 3 +b.
b=-18.
Finally, our desired line has the following equation:
y= 10/3 x -18
