alice took out 80/20 mortgage on a $232,000 home. what is the amount financed under the first mortgage?
Answer:
The amount financed under this mortgage is $185,600
Step-by-step explanation:
Alice took out an 80/20 mortgage on a $232,000 home.
80/20 mortgage means pay 20% down payment and 80% finance amount of home value.
Home value = $232,000
Now, we need to find finance amount from this hone value of $232,000
Let's calculate the 80% of $232,000 as finance amount;
Finance amount = 80% of 232000
Finance amount = 0.80 x 232000
Finance amount = 185,600
Hence, The amount financed under this mortgage is $185,600

Ken wants to build a table and put a border around it. The table and border must have an area of 3,276 square inches. The table is 36 inches wide and 72 inches long without the border. Which quadratic equation can be used to determine the thickness of the border, x? (2 points)
Group of answer choices
4x2 + 216x + 2,592 = 0
4x2 + 216x − 684 = 0
2x2 + 216x − 3,276 = 0
x2 + 108x + 3,276 = 0
Answer:
4x2+216x-684x
Step-by-step explanation:
solnA) The dimensions of the table are in inches
Let
x=the thickness of the border
we know that the table and the border must have an area of 3,276 square feet
convert the dimensions of the table to feet
remember that; 1ft =12in
36in=3ft
72in=6ft
i.e; 3,276 = (6+12x)*(3+2x)
solve for x
3276=6×3+ 6×2x +2x×3+ 4x²
3276=18+12x+6x+4x²
4x²+18x+18-3276=0
4x²+18x-3258
solnB) The dimensions of the table are in feet
Let
x=the thickness of the border
we know that the table and the border must have an area of 3,276 square feet
i.e 3,276 = ()×()
solve for x
3,276 = 72×36 + 72×2x + 2x×36 + 4x²
3,276 = 2,592 + 144x + 72x + 4x²
4x² + 216x + 2,592 + 3276 = 0
4x²+216× - 684= 0
therefore; the quadratic equation can be used to determine the thickness of the border =
4x² + 216x - 684 = 0
The diameter of a circle measures 28 m. What is the circumference of the circle?
Use 3.14 for y, and do not round your answer. Be sure to include the correct unit in your answer.
28 m
EX
Answer:
87.92 m
Step-by-step explanation:
The formula to calculate the circumference of the circle is:
Diameter * Pi ----> 28 * 3,14
Final answer:
The circumference of a circle with a 28 meter diameter is calculated using the formula C = \\(pi) \\times d, resulting in 87.92 meters as the circumference.
Explanation:
The question requires us to find the circumference of a circle given its diameter, which measures 28 meters. To calculate the circumference, we use the formula C = \\(pi) \\times d, where \\(pi) is approximately 3.14 and d is the diameter of the circle. Since the diameter is 28 meters, the circumference is calculated as follows:
C = 3.14 times 28 m = 87.92 m.
Therefore, the circumference of the circle is 87.92 meters.

about 55°. Ignoring the sag in the string,
find the height of the kite if 60 m of string
has been let out.

Answer:
49.15 m
Step-by-step explanation:
Length of the string is the hupotenuse: 60
Height of the kite is the opposite: X
sin(55) = opposite/hypotenuse
sin(55) = X/60
X = 60sin(55)
X = 49.14912266 m
The map shows the length (in miles) of shoreline along the Gulf of Mexica for each state that borders the body of water. What is the probability that a ship coming ashore at a random point in the Gulf of Mexico lands in the given state? Round your answers to the nearest whole percent.
Answer:
TX- 23%
AL- 3%
FL- 47%
LA- 24%
MS- 3%
Step-by-step explanation:
Final answer:
To find the probability of a ship coming ashore in a given state, divide the length of its shoreline by the total length of the Gulf of Mexico's shoreline.
Explanation:
To find the probability of a ship coming ashore at a random point in the Gulf of Mexico landing in a given state, we need to divide the length of the shoreline of that state by the total length of the Gulf of Mexico's shoreline. Let's assume there are 4 states that border the Gulf of Mexico: State A with 100 miles of shoreline, State B with 150 miles, State C with 200 miles, and State D with 250 miles. The total shoreline length of the Gulf of Mexico would be 700 miles (100 + 150 + 200 + 250).
Now, we can find the probability for each state by dividing its shoreline length by the total shoreline length. For example, for State A, the probability would be 100/700 which is approximately 0.1429 or 14.29%.
Following the same calculation, the probability for State B is 150/700 which is approximately 0.2143 or 21.43%, the probability for State C is 200/700 which is approximately 0.2857 or 28.57%, and the probability for State D is 250/700 which is approximately 0.3571 or 35.71%.

15-6 < 3x+6-6 ... subtracting 6 from both sides
9 < 3x
3x > 9 ... flip both sides of inequality, flip the inequality sign
3x/3 > 9/3 ... dividing both sides by 3

(b +4)(b +9)(c -5)(c +9)(k +2)(k +3)Step-by-step explanation:
Consider the product ...
(x +a)(x +b) = x^2 +(a+b)x +ab
You will notice that the linear term (a+b)x has a coefficient (a+b) that is the sum of the factors of the constant term (ab).
For problems like this, it is useful to be able to factor the constant term, so you can choose the factors with the appropriate sum.
Signs are important. If the constant is positive, its factors will have the same sign, both positive or both negative. If the constant is negative, its factors will have opposite signs.

The area of a rectangle is 344 square inches. If the rectangle is 16 inches wide, find the perimeter of the rectangle.
A. 67 inches
B. 72 inches
C. 75 inches
D. 80 inches
Answer:
C. 75 inches
Step-by-step explanation:
well if it's a rectangle then we would do A = L x W we are told the Width and the Area
344 = L x 16
344 / 16 = 21.5
P = L + L + W + W
16 + 16 + 21.5 + 21.5
16 + 16 = 32
21.5 + 21.5 = 43
32 + 43 = 75
the perimeter is 75 inches
Final answer:
To find the perimeter of the rectangle, we calculate the length by dividing the area by the width and then apply the perimeter formula. We find that the length is 21.5 inches and the perimeter is 75 inches.
Explanation:
To find the perimeter of the rectangle when the area is 344 square inches and the width is 16 inches, we need to use the area formula of a rectangle, which is Area = length × width. Since we have the area and the width, we can calculate the length:
Divide the area by the width to find the length: Length = 344 sq in / 16 in = 21.5 in.
Now, use the perimeter formula: Perimeter = 2 × (length + width).
Substitute the length and width into the formula: Perimeter = 2 × (21.5 in + 16 in) = 2 × 37.5 in = 75 inches.
The correct answer is C. 75 inches.
