Answer:

D. ( {x} - 2)^{2}  = 7

If you live 1.5 miles from school and you walk at a rate of 3mph, when should you leave home in order to arrive at school by 9:0
storchak [24]
<h3>Answer is  8:30 </h3>

Work Shown:

time = distance/speed

time = (1.5 miles)/(3 mph)

time = (1.5/3) hours

time = 0.5 hours

time = 30 minutes

It takes 30 minutes to walk to school, so you should leave a half hour before 9:00. Subtracting 30 minutes from 9:00 gets you to 8:30. If anything, you should start a little bit before 8:30 just in case something might slow you down for one reason or another.

A stock analyst deposited a total of $50,000 in two simple interest accounts. The annual simple interest rate on one account is
Xelga [282]
Let 
x = amount invested at 9% interest, and
50000-x = amount invested at 4% interest

Then
0.09x+0.04(50000-x)=0.06*50000
Solve for x
0.05x=3000-2000
x=20000

The analyst invested $20000 at 9% and $30000 at 4%.
