Consider a 15-year mortgage at an interest rate of 8% compounded monthly. The amount to be mortgaged is $130,000. After the first month's payment, what is the new outstanding principal?
Answers
To find the new outstanding principal after the first month's payment on a 15-year mortgage at an 8% interest rate compounded monthly, we calculate the monthly interest and subtract it from the original principal.
Explanation:To find the new outstanding principal after the first month's payment, we need to calculate the monthly interest and subtract it from the original principal. Here are the steps:
Convert the annual interest rate to a monthly rate by dividing it by 12: 8% / 12 = 0.67%.Convert the mortgage amount to a decimal: $130,000Calculate the interest for one month: $130,000 × 0.67% = $871.67Subtract the interest from the original principal: $130,000 - $871.67 = $129,128.33Therefore, the new outstanding principal after the first month's payment is $129,128.33.

The measure of [tex]m{\angle}b[/tex] is [tex]79^{\circ}[/tex].
Step-by-step explanation:
Given: Lines a and b are parallel to each other.
To find: The measure of the angle b.
Solution: It is given that Lines a and b are parallel to each other, thus using the parallel lines properties, we have
[tex]m{\angle}a=79^{\circ}[/tex] (Vertically opposite angles)
Now, [tex]m{\angle}a[/tex] and [tex]m{\angle}b[/tex] forms the corresponding angle pair, thus they are congruent.

The perimeter of a rectangle is 141 feet, and the length is twice the width. What are the dimensions of the rectangle?
What's the width of the rectangle and what's the length?
Answers
To find the width and length of the rectangle, we used the perimeter formula and the given relationship between length and width. The width of the rectangle is 23.5 feet and the length is 47 feet, which are found by dividing the perimeter by the sum of the multipliers of width and then multiplying the width by 2 to find the length.
Explanation:The student asked for help with finding the dimensions of a rectangle given its perimeter and a relationship between its length and width. To find the dimensions of the rectangle, we can use algebra.
Firstly, we know the formula for the perimeter (P) of a rectangle is P = 2l + 2w, where l is the length and w is the width. Since we are given that the perimeter is 141 feet and the length is twice the width (l = 2w), we can set up the following equation:
141 = 2(2w) + 2w
Simplifying the equation, we get:
141 = 4w + 2w
141 = 6w
w = 141 / 6
w = 23.5 feet
Since the length is twice the width, the length (l) is:
l = 2 × 23.5 feet
l = 47 feet
Therefore, the dimensions of the rectangle are a width of 23.5 feet and a length of 47 feet.
Shaquira is baking cookies to put in packages for a fundraiser. Shaquira has made

Shaquira wants to create identical packages of cookies to sell, and she must use all of the cookies.
What is the greatest number of identical packages that Shaquira can make?
Answers
Answer:
2
Step-by-step explanation:
To be able to find the greatest number of identical packages that Shaquira will be able to make, we first need to find the prime factors of the Chocolate Chip Cookies and Sugar Cookies.
86 Chocolate Chip Cookies
42 Sugar Cookies
Let's take the 86 Chocolate Chip Cookies first.
[tex]86 \left \{ {{2} \atop {43}} \right.[/tex] or 86 = 2 x 43
Now let's take the Sugar Cookies.
[tex]42 \left \{ {{2} \atop {21\left \{ {{3} \atop {7}} \right. }} \right.[/tex] or
42 = 2 x 3 x 7
Now that we have the prime factors, we then look for the Greatest Common Factor between the sets of prime factors.
2 x 3 x 7 = 42
2 x 43 = 86
2 = Total number of identical packages.

Two consecutive odd numbers are such that seven times the smaller, subtracted from nine times the bigger, gives 144. Find the numbers.
Answers
x-------------> first odd number
x+2----------> second consecutive odd number
we know that
seven times the smaller, subtracted from nine times the bigger, gives 144
then
9*(x+2)-7*x=144-----------> 9x+18-7x=144---------> 2x=126-----> x=63
the numbers are
63 and 65
The smaller odd number is 63, and the next consecutive odd number is 65.
To find the consecutive odd numbers, an algebraic equation is set up and solved, yielding the smaller odd number as 63 and the next consecutive odd number as 65.
To find two consecutive odd numbers meeting the stipulated condition, we will set up an algebraic equation. Let the smaller odd number be represented by n, then the next consecutive odd number is n + 2. The given condition is that seven times the smaller odd number subtracted from nine times the bigger odd number equals 144. This can be expressed as the equation 9(n + 2) - 7n = 144.
Solving the equation:
Expand the equation: 9n + 18 - 7n = 144Combine like terms: 2n + 18 = 144Subtract 18 from both sides: 2n = 126Divide both sides by 2: n = 63Therefore, the smaller odd number is 63, and the next consecutive odd number is 65.

b. What is the percent of change in membership from 2010 to 2011 for Troop B? Round to the nearest tenth of a percent, if necessary.
c. Which troop has the better record in terms of the number of new members?
d. Which troop has the better record in terms of the percent of change in membership?
Answers
A) 14.3%
B) 14.3%
C) Troop B
D) They are equal.
Explanation:
A) The percent of change is given by:
[tex]\frac{\text{amount of change}}{\text{original amount}}\times 100[/tex]
For Troop A, the amount of change is 16-14=2; the original amount is 14. This gives us:
[tex]\frac{2}{14}\times 100=14.3 \%[/tex]
B) The amount of change for Troop B is 24-21=3; the original amount is 21. This gives us:
[tex]\frac{3}{21}\times 100=14.3\%[/tex]
C) Troop A gained 2 more members, while Troop B gained 3; Troop B gained more new people.
D) Since the percent of change for each troop was equal, they both had an equal record in terms of percentage of new members.
Answer:
a. What is the percent of change in membership from 2010 to 2011 for Troop A?
[tex]\frac{16-14}{14}*100[/tex] = 14.28%
b. What is the percent of change in membership from 2010 to 2011 for Troop B?
[tex]\frac{24-21}{21}*100[/tex] = 14.28%
c. Which troop has the better record in terms of the number of new members?
Troop B.
d. Which troop has the better record in terms of the percent of change in membership?
Both have the same percentage change.

Ian is given some red licorice that is wrapped in a coil. Upon flattening the licorice, Ian discovers that the total length is 60 cm. He then cuts the licorice into two pieces so that the ratio of the lengths of the two pieces is 7:3. Each piece is then bent to form a square. What is the total area of the two squares?
Answers
1. First, let's find the ratio of the lengths.
Since the ratio is 7 to 3, we can find the length of each licorice piece by setting its proportion over 10, since that is the sum of the ratio. Thus, one licorice piece has a length of 60 * 7/10 = 42 cm and the other has a length of 60 * 3/10 = 18 cm.
2. Now, let's create our squares.
Each piece is bent to form a square. In other words, the pieces is split into 4 equal sides. Thus, we can divide our lengths by 4. The first piece of licorice made into a square has side lengths of 42/4 = 10.5 cm. The second piece of licorice has side lengths of 18/4 = 4.5 cm.
3. Finding the area of our squares.
Now, all we need to do is find the sum of the areas of the squares. The first square has an area of [tex]10.5^2 = 110.25[/tex] cm^2 and the second square has an area of [tex]4.5^2 = 20.25[/tex] cm^2. Thus, our answer is 130.5 cm^2.
