The error that Maria made is that she did not divide correctly.
<h3>What error did Maria make?
</h3>
The simple interest that is paid on an amount of money is a function of the amount deposited, time and interest rate.
Simple interest = principal x time x interest rate
2666 = 4300 x 0.062 x t
2666 = 266.60t
t = 2666 / 266.60
t = 10 years

Its the metric system thats the problem
Answer:
Step-by-step explanation:
<u>Find zeros first:</u>
- x² + x - 6 = x² + 3x - 2x - 6 = x(x + 3) - 2(x + 3) = (x - 2)(x + 3)
- x = 2, x = -3, x = 7 (but x ≠ 7 as no division by zero)
<u>We have 4 intervals:</u>
- x ≤ - 3, three negatives, the result is negative or zero
- -3 ≤ x ≤ 2, two negatives and one positive, the result is positive or zero
- 2 ≤ x < 7, two positives and one negative, the result is negative or zero
- x > 7, three positives, the result is positive or zero
<u>The solution is:</u>
Correct choice is A
Answer:
Distance to appointment point = 5 miles
Step-by-step explanation:
Let s be the distance to the appointment point,
We have Maria drove to a business appointment at 50mph in the morning.
Time taken in the morning
![t_m=\frac{s}{50}=0.02s](https://tex.z-dn.net/?f=t_m%3D%5Cfrac%7Bs%7D%7B50%7D%3D0.02s)
Her average speed on the return trip in the afternoon was 40 mph.
Time taken in the afternoon
![t_a=\frac{s}{40}=0.025s](https://tex.z-dn.net/?f=t_a%3D%5Cfrac%7Bs%7D%7B40%7D%3D0.025s)
Given that the return trip took 1/4hr longer because of traffic.
That is
![t_a-t_m=\frac{1}{4}hr=0.025hr](https://tex.z-dn.net/?f=t_a-t_m%3D%5Cfrac%7B1%7D%7B4%7Dhr%3D0.025hr)
Substituting
![t_a-t_m=0.025hr\\\\0.025s-0.02s=0.025\\\\s=5miles](https://tex.z-dn.net/?f=t_a-t_m%3D0.025hr%5C%5C%5C%5C0.025s-0.02s%3D0.025%5C%5C%5C%5Cs%3D5miles)
Distance to appointment point = 5 miles
