Darryl deposits $ 1,500.00 into a savings account that has a simple interest rate of 2.7% Lori deposits $ 1,400.00 into a savings account that has a simple interest rate of 3.8% If no other transactions are made whose account will have more money after 10 years?
Answer:
Daryl
He deposits $1,500 at an interest rate of 2.7%
We now turn the percentage into a decimal 2.7%--->0.027
We multiply $1,500 x [tex]1.027^{10}[/tex] to get 1,957.92
Lori deposits $1,400 at an interest rate of 3.8%
We once again turn the percentage into a decimal 3.8%--->0.038
We multiply $1,400 x [tex]1.038^{10}[/tex] to get 2032.83
Meaning Lori has more at the ned of the 10 years

1. For a party, Susan estimated there would be 14 people in attendance, but only 12 showed up. What was the percent error in her estimation?
2. Find the percent error in this situation:
Estimated value: 231
Actual value: 215
3. Find the percent error in this situation:
Experimental value: 16.5 sec
Theoretical value: 17.1 sec
4. Find the percent error in this situation:
Estimated value: 1081
Actual value: 1150
The formula for percent error is:
((Approximate value - exact value) / exact value) x 100
1) 14-12 = 2
2/12 = 0.1666
0.166 x 100 = 16.7% (Rounded to nearest tenth)
2) 231 - 215 = 16
16/215 = 0.74419
0.74419 x 100 = 7.4419% ( Round as needed)
3) 17.1 - 16.5 = 0.6
0.6/16.5 = 0.36364
0.36364 x 100 = 3.6364% (Round off as needed)
4) 1081 - 1150 = -69
-69/1150 = -0.06
-0.06 x 100 = -6% = 6% error
Answer:
1) 85.7%
2) 93%
3) 96.5%
4) 94%

Which statements apply to the expression (three-fifths) cubed? Check all that apply. The base is Three-fifths. The base is 3. The exponent is 3. The expanded form is Three-fifths times three-fifths times three-fifths. The expanded form is StartFraction 3 times 3 times 3 Over 5 EndFraction. (Three-fifths) cubed = StartFraction 9 Over 15 EndFraction (Three-fifths) cubed = StartFraction 27 Over 125 EndFraction
Answer:
The answers are 1, 3, 4, 7
the base is 3/5
the exponent is 3
the expanded form is 3/5 x 3/5 x 3/5
