Lilliana is training for a marathon. She runs the same distance every day for a week. On Monday, Wednesday, and Friday, she runs 2 laps on a running trail and then runs 6 more miles. On Tuesday and Sunday, she runs 4 laps on the trail and then runs 2 more miles. On Saturday, she just runs laps. How many laps does Lilliana run on Saturday?

Answers

Answer:

6 Laps

Step-by-step explanation:

3 laps + 6 miles = 5 laps + 2 miles.

Subtract miles over.  3 laps + 4 miles = 5 laps.

Subtract laps over.  4 miles = 2 laps.

Simplify.  2 miles = 1 lap.

Plug it in to one of the equations. 5 laps + 2 miles = Your answer.

2 miles = 1 lap. 5 laps + 1 lap = 6 laps.

Your answer is 6 LAPS.

-2/3 divided by (-1/2)

Answers

Answer:

4/3

Step-by-step explanation:

multiply by the reciprocal

[tex]-\frac{2}{3}[/tex] × [tex]-\frac{2}{1}[/tex] = [tex]\frac{4}{3}[/tex]

Answer: +4/3

Explanation: It's important to understand that dividing by a fraction

means the same thing as multiplying by the reciprocal of that fraction.

In other words, we can simply change the division symbol

to multiplication and flip the second fraction.

So we can rewrite this problem as -2/3 · -2/1.

We can't cross-cancel anything.

Before multiplying, take note of your signs.

A negative times a negative is a positive,

so we know that our answer will be positive.

Multiplying across the numerators and denominators, we have +4/3.

In a laboratory experiment, two mice will be placed in a simple maze with one decision point where a mouse can turn either left (L) or right (R). When the first mouse arrives at the decision point, the direction it chooses is recorded. Then, the process is repeated for the second mouse.

The tree diagram should be drawn where the first stage represents the decision made by the first mouse and the second stage represents the decision made by the second mouse.

Determine all four possible decision outcomes for the two mice.


Using the information from the previous problem, answer the following question.

If the probability of turning left is 0.5 and the probability of turning right is 0.5 for each mouse, what is the probability that only one of the two mice will turn left?

1. P is the principal amount, $630.00.
r is the interest rate, 6.5% per year, or in decimal form, 6.5/100=0.065.
t is the time involved, 4....year(s) time periods.
So, t is 4....year time periods.
To find the simple interest, we multiply 630 × 0.065 × 4 to get that:
The interest is: $163.80

2. =8000 x 9 x 18
=12,960
Total amount = 12960 +8000=
$20,960
3. annual interest rate = 15.9 %
initial charge = $126
to get the annual interest paid = 15.9% of $126
= 0.159 * $126 = $20.03
monthly interest paid would be = annual interest / 12 months
= 20.03 / 12 = $1.67
hence in 2 months Rita will pay = initial charge + monthly interest * 2
= $126 + $ 1.67 *2 = $ 126 + $3.34
= $ 129 .34

4. To find the amount of money in the account after 8.5 years we will first turn 5.6% into a decimal. We'll do that by moving the decimal within the percentage two places to the left. That leaves us with 0.056.
Next, we'll multiply our factors to help us find out how much interest will be accrued within the 8.5 years.
500 x 0.056 x 8.5 = 238.
Margarito will earn $238 within an 8.5 year time frame.
Since her original deposit was $500 and assuming no other deposits/withdrawls occur within the time frame, we will add $238 of interest to the original deposit.
500 + 238 = 738.
This means, that Margarito will have $738 in her savings account after 8.5 years of just accruing interest.

5. $18,260 divided by (/) $220,000 = .083 or .08. The interest is 8%.
Because Kelli is earning $18,260 a year, you need to get the number down to a decimal (which would be the interest) So, you have to divide the smaller number by the larger number. I use
x 18260
____ _______
100 % 220000
multiply 100x18260 and then divide by 220000. You get 8.3, or 8.3%, but if you round up, you get 8%.
1. 163.80
2. 12,960
3. 3.34
4. 738
5. 8.3%
