Your parents have a credit card with a balance of $3,287.90 at an interest rate of 14.5% APR. They pay $1,200.00 each month on the due date until the card is paid off. How many months does it take to pay off the card, and what is the total amount paid including interest?
Each month, the interest for the current balance is calculated as:
$3,287.90 * 14.5% / 12 = $48.22
How Do Interest Rates Work?
The amount a lender charges a borrower is called an interest rate, and it is expressed as a percentage of the principal, or the loaned amount. Typically, a loan's interest rate is expressed as an annual percentage rate, or APR (APR).
The new balance after each payment is:
$3,287.90 + $48.22 - $1,200.00 = $2,147.12
Repeat the calculation until the balance is zero:
Month 1:
Balance: $3,287.90
Interest: $48.22
New Balance: $2,147.12
Month 2:
Balance: $2,147.12
Interest: $31.14
New Balance: $1,178.26
...
Month 26:
Balance: $0.00
So, it takes 26 months to pay off the credit card, and the total amount paid including interest is $31,622.68.

What is Triangle?A triangle is a two dimensional figure which consist of three vertices, three edges and three angles.
Sum of the interior angles of a triangle is 180 degrees.
We have the law of sine of triangles, which is stated as,
a / sin A = b / sin B = c / sin C
where a, b and c are the sides opposite to the angles of the triangle A, B and C respectively.
Given, In ΔOPQ, m ∠O=113° and m ∠P=18°.
m ∠Q = 180° - (m ∠O + m ∠P)
= 180° - (113° + 18°)
= 49°
q / sin Q = o / sin O
o = (q / sin Q) (sin O)
= (75 / sin 49°) (sin 113°)
= (75 / 0.7547) (0.9205)
= 91.476 cm
≈ 91 cm
Hence the length of o is 91 cm.

Terry is skiing down a steep hill. Terry's elevation, E(t), in feet after t seconds is given by E(t)=2600−50t.
Part 1) Terry started at an elevation of 2,600 ft.
Part 2) The elevation is decreasing by 50 feet per second.
we have
E(t) = 2600 -50t
where
E(t) is Terry's elevation in feet
t is the time in seconds
Part 1) For t=0
substitute the value,
E(0) = 2600 -50(0)
E(0) = 2600
therefore
The equation says us that Terry started at an elevation of 2,600 ft
Part 2) we have
E(t)=2600−50t
This is the equation of the line in slope-intercept form.
The slope m is equal to, m = -50 ft/sec
The slope is negative because is decreasing

The city is building a rectangular parking lot. The city wants the width of the parking lot to be 8 yards. The area of the parking lot must be at most 80 square yards. (These are city regulations.) Write an Inequality that describes the possible lengths (in yards) of the parking lot.
Use l for the Length of the rectangular parking lot.
Answer:The area of the parking lot is length * width. If the width of the parking lot is 8 yards, the area of the parking lot can be represented by the inequality:
Area <= 80
length * 8 <= 80
To get the possible lengths of the parking lot we need to divide both sides by 8:
length <= 10
Therefore, the inequality that describes the possible lengths of the parking lot (in yards) is:
length <= 10 yards
The possible lengths of the parking lot is any value less than or equal to 10 yards.

what are the coordinates of the point on the directed line segment from (1,5) to (6,10) that portions the segment into a ratio of 3 to 2?
Answer:
The answer is point (4,8)
Step-by-step explanation:
The horizontal (x) distance between the given points is 6-1 = 5.
If the horizontal distance is 5, then because the ratio of the given points is 3 to 2, we can say that 3/5 of 5 is 3. The horizontal distance between (1,5) and (x,y) is 3, so x = 4.
We can do the same with the vertical (y) distance, which is 10-5 = 5.
Again, 3/5 of 5 is 3, so y = 5+3 = 8
Answer: the point is (4,8).
CHECK: We can check this result by finding the distances between the given points to (4,8), and calculating the distance.
Distance between (1,5) and (4,8) = √18 = 3√2
Distance between (6,10) and (4,8) = √8 = 2√2
The ratio between the distances is 3:2, so the solution checks out.

Write and solve an

Answer:
Step-by-step explanation:
Let r be the cost of each juice bottle.
The total cost of the juice bottles is 10 * r = 10r.
The total cost of the apples and the juice is $1.59 + 10r = $7.39.
We can set up an equation using the above information:
$1.59 + 10r = $7.39
10r = $7.39 - $1.59 = $5.80
r = $5.80 / 10 = $0.58
Therefore, each juice bottle costs $0.58.

How to obtain the area of the shaded region?The area of a triangle is given by half the multiplication of the base and of the height of the triangle.
For the triangle, the area is of 30 cm², while the height is of 6 cm, hence the base is obtained as follows:

3b = 30
b = 30/3
b = 10 cm.
Considering the side length of 10 cm², the area of the square is given as follows:
