Which of the following equations represents the value of a savings account at the Owl Credit Union at Dundalk High School that has an initial
deposit of $250 and pays an annual interest rate of 2%?

Answers

Answer:

Step-by-step explanation:

Given

Initial deposit (Principal)= $250

Rate = 2%

Time = 1year (annual interest)

Required

Amount after 1 year

First we need to calculate interest

Interest = PRT/100

Interest = 250*2*1/100

Interest 2.5 * 2

Interest = $5.0

Next is to calculate amount;

Amount = Principal + Interest

Amount = $250 + $5

Amount = $255

Hence the value of a savings account at the Owl Credit Union at Dundalk High School that has an initial  deposit of $250 and pays an annual interest rate of 2% is $255.

Amount = P + I

Value of savings account is $255

Simple Interest rate;

Given that:

Initial deposit = $250

Annual interest rate = 2% = 0.02

Find:

Equations represents value of savings account

Computation:

Equations represents value of savings account = P + PRT

Equations represents value of savings account = 250 + (250)(0.02)(1)

Equations represents value of savings account = 250 + 5

Equations represents value of savings account = $255

An equation of a line perpendicular to the line represented by the equation y = -
1/2 x - 5 and passing through (6,4) is what?

Answers

Answer:

y= 1/2x+1

Step-by-step explanation:

Answer:

[tex]y=2x-8[/tex]

Step-by-step explanation:

First, remember that perpendicular lines have opposite and reciprocal slopes to the original line. That means for this line, your slope will be 2 (flip the fraction and change the sign). So we have:

[tex]y=2x+b[/tex]

Next, plug in the point that it passes through in order to find the y-intercept (b).

[tex]4=2(6)+b[/tex]

[tex]4=12+b[/tex]

[tex]b=-8[/tex]

So your equation will be:

[tex]y=2x-8[/tex]

Franklin school is having a Popsicle party for its nine hundred fifty four students.The secretary there will some Popsicle left over to share with the teachers. Each student will get two Popsicle. Popsicle come in boxes that have one dozen Popsicle. There are twenty-five boxes in cartoon, how many boxes of Popsicle? Show your work.

Answers

Answer:

175 boxes

Step-by-step explanation:

There are a total of 954 students since each student will get two popsicles that would mean we need a total of 1,908 popsicles (954 * 2). Since each box contains 12 popsicles then we simply divide the total number of popsicles needed by the number of popsicles that fit in each box to find the total number of boxes.

1,908 / 12 = 159 boxes

Since there are 25 boxes per carton we divide 159 by 25

159 / 25 = 6.36

Now we see that we need at least 6.36 cartons of popsicles, but since we can't get 6.36 we would need to get 7 cartons which would bring a total of

7 * 25 = 175 boxes

Finally, we would end up with 175 boxes of popsicles which would be enough for all the students and have leftover for the teachers.

A group of ‘n' friends decided to rent a condominium for a one week vacation in Florida. They decided to share the weekly rent of ‘m' dollars equally. If due to an unanticipated reason two members of the group couldn't make the trip, and the rest of the friends decided not to charge the two who pulled out for the rent; what will be the additional amount each of the remaining friends must pay for renting the condominium?

Answers

Answer:

2m / n² - 2n

Step-by-step explanation:

Given that:

Number of friends = n

Weekly rent = $m

To share rent fee equally :

Each friend will pay : $m / n

If 2 of the friend couldn't make the trip:

Additional amount to be shared by the others = 2(m/n) = 2m/n

Hence additional fee per friend who eventually made the trip:

Additional amount to be shared / number of friend who eventually made the trip

= (2m/n) ÷ (n - 2)

= 2m / n * 1 / n - 2

= 2m / n(n-2)

= 2m / n² - 2n

When dividing each of the numbers $$3759$$ and $$4139$$ by some positive integer number, the remainder happened to be equal to $$16$$. What is the smallest possible value of the divisor?

Answers

Answer:

The smallest possible value of the divisor is 19

Step-by-step explanation:

The given numbers for division are;

3759 and 4139, the remainder = 16

Let x represent the number

Therefore, we have;

x > 16

x is a factor of 3759 - 16 = 3743, and x is also a factor of 4139 - 16 = 4123

The factors of 3743 obtained from an online resource are 1, 19, 197, 3759

The factors of 4123 obtained from an online resource are 1, 7, 19, 31, 133, 217, 589, 4123

The common factors of 3743 and 4123 are 1, 19

Given that x > 16, we have, x = 19

Therefore, the smallest possible value that will divide both 3759 and 4139 whereby the remainder is 16 = 19

Sonia Sotomayor.Let us not forget that between the appointments of Justice Sandra Day O'Connor in 1981 and Justice Ginsburg in 1992, eleven years passed. Similarly, between Justice Kaye's initial appointment as an Associate Judge to the New York Court of Appeals in 1983, and Justice Ciparicks appointment in 1993, ten years elapsed. Almost nine years later, we are waiting for a third appointment of a woman to both the Supreme Court and the New York Court of Appeals and of a second minority, male or female, preferably Hispanic, to the Supreme Court. In 1992 when I joined the bench, there were still two out of 13 circuit courts and about 53 out of 92 district courts in which no women sat. At the beginning of September of 2001, there are women sitting in all 3 circuit courts. The First, Fifth, Eighth and Federal Circuits each have only one female judge, however, out of a combined total number of 48 judges. There are still nearly 37 district courts with no women judges at all. For women of color the statistics are more sobering. As of September 20, 1998, of the then 195 circuit court judges, only two were African-American women and two Hispanic women. Of the 641 district court judges, only twelve were African-American women and eleven Hispanic women. African-American women comprise only 1.56% of the federal judiciary and Hispanic-American women comprise only 1%. No African-American, male or female, sits today on the Fourth or Federal circuits. And no Hispanics, male or female, sit on the Fourth, Sixth, Seventh, Eighth, District of Columbia or Federal Circuits.Sort of shocking, isn't it? This is the year 2002. We have a long way to go. Unfortunately, there are some very deep storm warnings we must keep in mind. In at least the last five years the majority of nominated judges the Senate delayed more than one year before confirming or never confirming were women or minorities. I need not remind this audience that Judge Paez of your home Circuit, the Ninth Circuit, has had the dubious distinction of having had his confirmation delayed the longest in Senate history. These figures demonstrate that there is a real and continuing need for Latino and Latina organizations and community groups throughout the country to exist and to continue their efforts of promoting women and men of all colors in their pursuit for equality in the judicial system.The rhetorical technique most used in this excerpt isparallelism.overstatement.ethos.shift.
