Many credit card companies charge a compound interest rate of 1.8% per month on a credit card balance. Miriam owes $650 on a cre

Sauron [17]

Answer:

<u>The correct answer is D. 650.oo, 661.70, 673.61, 685.74, 698.08</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Compound interest rate charged by Miriam's credit card company = 1.8% monthly

2. If she makes no purchases or payments, she will go more and more in debt. Which of the following sequences describes her increasing monthly balance?

Miriam's current credit card balance = US$ 650

Miriam's credit card balance in one month = 650 * 1.018

Miriam's credit card balance in one month = 661.70

Miriam's credit card balance in two months = 661.70 * 1.018

Miriam's credit card balance in two months = 673.61

Miriam's credit card balance in three months = 673.61 * 1.018

Miriam's credit card balance in three months = 685.74

Miriam's credit card balance in four months = 685.74 * 1.018

Miriam's credit card balance in four months = 698.08

<u>The correct answer is D. 650.oo, 661.70, 673.61, 685.74, 698.08</u>

Ron walks 0.5 mile on a track in 10 minutes. Stevie walks 0.25 mile on the track in 6 minutes find the unit rate for each walker

Firlakuza [10]

Answer:

Ron's speed = 3 miles/hour

Stevie's speed = 2.5 miles/hour

On comparing we see Ron is walking faster than Stevie.

Step-by-step explanation:

Given:

Ron takes 10 minutes to walk on a track to cover a distance of 0.5 miles

Stevie takes 6 minutes to walk on a track to cover a distance of 0.25 miles

To find their unit rates in mile per hour and choose the faster one.

Solution:

Unit rate in miles per hour signifies their speeds. Thus, we will find out their speeds.

Ron:

Distance= 0.5 miles

Time = 10 minutes = $10\ min\times \frac{1\ hr}{60\ min}=\frac{1}{6}$ hours

Speed = $\frac{Distance}{Time}=\frac{0.5}{\frac{1}{6}}=0.5\times6=3\ miles/hour$

Stevie

Distance = 0.25 miles

Time = 6 minutes = $6\ min\times \frac{1\ hr}{60\ min}=\frac{1}{10}$ hours

Speed = $\frac{Distance}{Time}=\frac{0.25}{\frac{1}{10}}=0.25\times10=2.5\ miles/hour$

Thus, we have

Ron's speed = 3 miles/hour

Stevie's speed = 2.5 miles/hour

On comparing we see Ron is walking faster than Stevie.

Find the value of c that makes each trinomial a perfect square.

gavmur [86]

Answer:

The answer to your question is the letter a.

Step-by-step explanation:

Data

x² + 12x + c

If this trinomial is a perfect square trinomial, the third term must be half the second term divided by the square root of the first term, and to the second power.

-Get half the second term

12x/2 = 6x

-Divide by the square root of the first term

6x/x = 6

-Express the result to the second power

6² = 36

-Write the perfect square trinomial

(x² + 12x + 36) = (x + 6)²
