Mathematics
1 answer:
Tanya [424]2 years ago
8 0

Answer:

10d or less

Step-by-step explanation:

Joanne would want $50 left, and she has $250. 20 - 50 is 200. 20 goes into 100 5 times.

20 goes into 200 10 times. You just add five. (20, 40, 60, 80, 100)

If she wants at least $50 left, she would have to limit how many Dvd's she buys to 10 or less.

3/10 divided by -1/3
Snezhnost [94]

Answer:

-9/10

Step-by-step explanation:

  1. Find the LCM of 10 and 3: 30
  2. Alter the numerators to fit the denominators: 3 × 3 = 9, -1 × 10 = -10
  3. Re-write the fractions: 9/30 ÷ -10/30
  4. 9/30 ÷ -10/30 = 9/30 × -30/10
  5. 9/30 × -30/10 = -270/300
  6. -\frac{270}{300} = -\frac{9}{10}  

I hope this helps!

A bank loans a family $90,000 at 4.5% annual interest rate to purchase a house. The family agrees to pay the loan off by making
Naily [24]

Using it's formula, it is found that the monthly payment should be of $688.49 in order to pay off the debt in 15 years.

<h3>What is the monthly payment formula?</h3>

It is given by:

A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}

In which:

  • P is the initial amount.
  • r is the interest rate.
  • n is the number of payments.

For this problem, the parameters are given as follows:

A = 90000, r = 0.045, n = 15 x 12 = 180.

Hence:

r/12 = 0.045/12 = 0.00375.

Then we solve for A to find the monthly payment, as follows.

A = P\frac{\frac{r}{12}\left(1 + \frac{r}{12}\right)^n}{\left(1 + \frac{r}{12}\right)^n - 1}

A = 90000(0.00375)\frac{(1.00375)^{180}}{(1.00375)^{180} - 1}

A = $688.49
