Answer:
Keisha will owe $18444.32 after 9 years
Step-by-step explanation:
Compound Interest
It occurs when the interest is added to the principal rather than paying it in.
It basically means paying interest over interest.
The formula is:
[tex]\displaystyle A=P\left(1+{\frac {r}{n}}\right)^{nt}[/tex]
Where:
A = final amount
P = initial principal balance
r = interest rate
n = number of times interest applied per time period
t = number of time periods elapsed
Keisha borrowed P = $8000 at a rate of r = 9.5% = 0.095 (assumed annual rate) compounded semiannually (twice a year).
If she makes no payments, the amount she owes increases over time. After t = 9 years, we can calculate the amount owed by using the above formula.
Please, note that since there are 2 compounding periods per year, n = 2, thus:
[tex]\displaystyle A=8000\left(1+{\frac {0.095}{2}}\right)^{2\cdot 9}[/tex]
Operating:
[tex]\displaystyle A=8000\left(1+0.0475\right)^{18}[/tex]
[tex]A = 8000\cdot 2.30554[/tex]
A = $18444.32
Keisha will owe $18444.32 after 9 years

Y=5X+2
When x =1 5(1)+2= 7 for Y
When X=2 5(2)+2= 12 for Y
When X =-1 5[-1)+2/ -3
Coordinates (1,7).(2,12)(-1,-3)
Step-by-step explanation:
please help me on this
Answer:
x = 3
Step-by-step explanation:
7(2 - x) - 5(x - 1) = -6x + 1 (distribute the 7 and the 5)
14 -7x -5x + 5 = -6x + 1 (collect like terms)
-12x + 19 = -6x + 1 (add 12 on both sides)
19 = 6x + 1 (subtract 1 on both sides)
18 = 6x (divide by 6 on both sides)
3 = x

Can every parallelogram be changed into a rectangle
with equal area? Explain.
Answer:
Every parallelogram can be made into a rectangle, which is why we use the same formula to find the area of a parallelogram and a rectangle.
Step-by-step explanation:
Because the parallelogram and rectangle are composed of the same parts, they necessarily have the same area.

En el siguiente esquema se presentan en rojo las diferentes rutas que existen para llegar de una ciudad a otra. Por ejemplo, para llegar de la ciudad B a la ciudad C hay 4 posibles rutas. Si se quiere viajar desde la ciudad A a la ciudad D, ¿por cuántas rutas se podría ir? * A. 14 B. 36 C. 12 D. 24
Answer:
La respuesta es D. 24
Step-by-step explanation:
Falta el esquema. Lo adjunto en la resolución de la pregunta.
En el esquema se puede ver que hay 3 maneras de ir desde la ciudad A a la ciudad B, 4 maneras de ir desde la ciudad B hacia la ciudad C y finalmente 2 maneras de ir desde la ciudad C hacia la ciudad D.
Necesitamos saber por cuántas rutas se podría ir si se desea viajar desde la ciudad A a la ciudad D.
Utilizaremos el principio de multiplicación para responder a ésta pregunta ⇒
Supongamos que estamos realizando un experimento [tex]N[/tex] el cuál está conformado por una serie de sub - experimentos [tex]m_{1},m_{2},...,m_{n}[/tex].
Ahora, cada uno de estos sub - experimentos se puede desarrollar de [tex]n_{1},n_{2},...,n_{n}[/tex] maneras diferentes respectivamente. Entonces, el número total de maneras diferentes en las que el experimento [tex]N[/tex] se puede llevar a cabo se calcula como [tex]n_{1}[/tex] x [tex]n_{2}[/tex] x . . . x [tex]n_{n}[/tex]
Ahora bien, siguiendo con ésta idea escribimos :
3 x 4 x 2 = 24
''3'' porque es el número de rutas distintas para ir de A hacia B
''4'' porque es el número de rutas distintas para ir de B hacia C
Y finalmente ''2'' porque es el número de rutas para ir desde C hacia D
Si hacemos éste producto el resultado es 24 y por lo tanto la opción correcta es D. 24
. On the opening night of a new movie, a local movie theater sold 630 tickets and filled 90% of the seats in the theater. How many seats are in the movie theater?
Answer:
700 seats
Step-by-step explanation:
- If 630 tickets filled 90% of the seats, [tex]x[/tex] tickets filled 100% of the seats
multiply 630 by 630 tickets = 90/100
- Set up a proportion
630 tickets/90 = [tex]x[/tex] tickets/100
[tex]x[/tex] = 700 tickets = 700 seats

I thought of a two-digit number. The unit digit of my number is a prime number, and the tens digit is four times as big as the unit digit. What is my number?
Please help! I'm very bad at these "what's my number" problems, so please respond ASAYC! (as soon as you can)
====================================================
Explanation:
Let A be the tens digit and B be the units digit
We can write the number as AB. So if A = 9 and B = 2 for instance, then the number is AB = 92. Keep in mind I'm not multiplying A and B here.
"The unit digit is a prime" means B could be any of these values {2,3,5,7}. We only list the single digit primes. The value 1 is not prime.
Now multiply each of those items by 4
4*2 = 8
4*3 = 12
4*5 = 20
4*7 = 28
Of those results, only 4*2 = 8 leads to a single digit answer.
This must mean that A = 8 and B = 2
Therefore the number is AB = 82.

please help find the top angle
Answer:
130 degrees
Step-by-step explanation:
So u can see those little lines on two of the sides of the triangle, it means that it's congruent also meaning the same length, and if u didn't, the angles had to be the same in order for the sides to be the same length. So the other missing angle degree is also 25 degrees. A triangle is 180 degrees, so with this info:
25 + 25 + 4x + 2 = 180
4x + 52 = 180
4x = 128
x = 32, now we have x so replace the x in the equation with 32
4(32) + 2
128 + 2
130

The simple interest formula is I=Prt, where I is the interest, P is the principal, r is the interest rate, and t is the time.
What is the interest rate if the principal is $25,000, the interest is $10,875, and the time is 15 years?
Answer:
$40781250
Step-by-step explanation:
Okay so the formula for simple interest is: I = P x T x R divided by 100
25000 x 10875 x 15 = 4078125000 / 100 = $40781250
If you have the multiple choice answers:
A. $160
B. $200
C. $1600
D. $16,000
the answer is C. $1600
here's why:
The principal is $10,000, the interest rate is 2%, and the time is 8 years.
I = Prt
= $10,000 · 2% ⋅ 8
= 10,000 ⋅ 0.02 ⋅ 8
= 1600
So, the interest earned is $1600.
