Convert the credit card rate to the APR. Ohio, 0.02192% daily rate. Please round your answer to the nearest percent. (zero decim

kogti [31]

Answer:

8%

Step-by-step explanation:

APR means annual percentage rate.

To convert the daily rate to an APR, multiply the daily rate by the number of days in a year

365 days = 1 year

0.02192% x 365 = 8.0008%

To round off to the nearest percent, look at the first number after the decimal, if it is less than 5, add zero to the units term, If it is equal or greater than 5, add 1 to the units term.

The tenth digit is 0, so the number would be rounded off to 8%

Suppose that Marlie had decided to apply for a private loan rather than a federal loan. She has

34kurt

Using simple interest, and considering a loan of $5,000, it is found that:

a) Her monthly payment is of $74.17.

b) She will pay back $8,900.

c) The total interest amount is of $3,900.

The amount of money after t years in simple interest is modeled by:

$A(t) = A(0)(1 + rt)$

In which:

A(0) is the initial amount.

r is the interest rate, as a decimal.

In this problem:

The loan is of $5,000, hence $A(0) = 5000$ .

The APR is of 7.8%, hence $r = 0.078$

10 years, hence $n = 10$

Item b:

$A(10) = 5000[1 + 0.078(10)] = 8900$

She will pay back $8,900.

Item a:

$8,900 will be paid in 10 x 12 = 120 months, hence:

$M = \frac{8900}{120} = 74.17$

Her monthly payment is of $74.17.

Item c:

Loan of $5,000, pays back $8,900, hence:

8900 - 5000 = 3,900

The total interest amount is of $3,900.

The radius of a circle is decreasing at a rate of 6.56.56, point, 5 meters per minute. At a certain instant, the radius is 12121

Ilia_Sergeevich [38]

Answer:

The rate of change of the area of the circle is approximately $-490.09 \ m^2/min$ .

Step-by-step explanation:

Given:

$\frac{dr}{dt} = -6.5 \ m/min$

radius $r =12 \ m$

We need to find the rate of change of the area of the circle at that instant.

Solution:

Now we know that;

Area of the circle is given by π times square of the radius.

framing in equation form we get;

$A= \pi r^2$

to find the rate of change of the area of the circle at that instant we need to take the derivative on both side.

$\frac{dA}{dt}=\frac{d(\pi r^2)}{dt}\\\\\frac{dA}{dt}= 2\pi r \frac{dr}{dt}$

Substituting the given values we get;

$\frac{dA}{dt}= 2\times \pi \times 12 \times -6.5\\\\\frac{dA}{dt}\approx -490.09 \ m^2/min$

Hence The rate of change of the area of the circle is approximately $-490.09 \ m^2/min$ .

M men and w women seat themselves at random in m+w seats arranged in a row. find the probability that all the women will be adja

WINSTONCH [101]

The correct answer is:

$\frac{(m+1)!w!}{(m+w)!}$

Explanation:

We want all w women to be seated together. There are w! ways to do this.

Since all women are seated together, we consider the as 1 block to be seated with the men.

There are m! ways of arranging the men. However, we also have the 1 block of women to seat; this makes (m+1)! ways to seat the men and block of women.

There are (m+w)! ways to arrange all of the men and women.

This makes our probability

$\frac{(m+1)!w!}{(m+w)!}$ .

For example, if there are 4 men and 3 women:

There are 3! = 6 ways to seat the women together. This makes 1 block of women.

There are 4! = 24 ways to seat the men together. Taking this with the block of women, we have (4+1)! = 5! = 120 ways to seat the men and block of women.

There are (4+3)! = 7! = 5040 ways to arrange 7 people.

This makes our probability 120(6)/5040 = 720/5040.
