Shirley has a credit card that uses the previous balance method. The opening
vesna_86 [32]

Answer:

= $44.19

Step-by-step explanation:

APR = 19%

Billing cycle = 30 days

Balance = $2830

Let's first find the daily rate,

Daily rate =  \frac{0.19}{365} = 0.000521

The daily rate = 0.000521

To calculate the amount Shirley was charged interest for the billing cycle, we use:

Daily rate * billing cycle * balance

Where,

Daily rate

=  \frac{0.19}{365}

Billing cycle = 30 days

Balance = $2830

Therefore, expression to be used =

(\frac{0.19}{365}  * 30) * 2830 \\= $44.19

denis-greek [22]

Answer:

c. 441ft^2

Step-by-step explanation:

Area is height times length and since it's a square, safe to say that the sides are equal in length. So square root both of the given areas of the 2 square:

\sqrt{841} = 29

\sqrt{400} = 20

Now u have side b and c of the triangle, it's a right triangle so use the Pythagorean theorem a^2 + b^2 = c^2

a^2 + b^2 = c^2

a^2 + 20^2 = 29^2

a^2 + 400 = 841

subtract 4 from both sides

a^2 = 441

square root both sides

\sqrt{a^2} = \sqrt{441}

a = 21

Now the side a of the triangle is also a side of the small square therefore

21^2 = 441

Using conversions of mixed numbers, the numbers that are equivalent to 2 and 7/9 are given by:

25/9 and 2.777.

<h3>What are the conversions of the mixed number 2 and 7/9?</h3>

To convert to decimal, we just add the integer part with the fractional part converted to decimal(dividing the numerator by the denominator), hence:

2 and 7/9 = 2 + 7/9 = 2.7777.

To convert to fraction, the procedure is similar, we just apply the least common multiple to add the fraction, as follows:

2 + \frac{7}{9} = \frac{2 \times 9 + 7}{9} = \frac{25}{9}

Hence the numbers that are equivalent to 2 and 7/9 are given by:

25/9 and 2.777.

An athlete ran 800 meters in 160 seconds. What was his rate in meters per minute? Enter your answer in the box.
FromTheMoon [43]

The athlete's average speed was 300 meters/minute.

<h3>How to calculate the speed of the athlete?</h3>

To calculate the speed of the athlete we must perform the following operations.

Divide the distance into the total time:

  • 800m ÷ 160sec = 5m/sec

Transform the value from seconds to minutes, for which we must multiply 5 by 60 because each minute is made up of 60 seconds.

  • 5m/sec × 60sec = 300m/min

According to the above, the average speed of the athlete is 300m/min.
