Cuanto cuestan 4 camisetas a $16,000 la docena?

Y_Kistochka [10]

Lo siento, no sé español, pero lo intenté.

Si se trata de "$ 16,000" para una docena de camisas que es 12, se dividiría "16,000 entre 12". Luego obtendrás 1,333.3 para multiplicar eso por 4 y luego obtendrás 5,333.3 a lo que responderás.

Esta es la ecuación,
16,000 / 12 = 1,333.3 x 4 = 5,333.3

Espero que esto ayude :-)

If Sheila paid $797.50 in interest on a 5 year loan of $5,800 for her first car, what was the interest rate? (Make sure you’ve c

allochka39001 [22]

In calculating the interest on a car we have a formula

(interest rate/number of payments) x loan principal = interest.

Since, we have:
Interest rate = ?
number of payments = 60 ( 5 year loan x 12 months)
loan principal = 5800
interest = 797.50

We need to derive a formula to find the IR(interest rate)

(interest rate/60) x 5800 = 797.50
IR (5800) / 60 = 797.50
IR (5800) = 797.50 (60)
IR (5800) = 47850
IR = 47850/5800
IR = 8.25 %

What is the zero of the function

olga_2 [115]

Answer:

$x=6$ (or 6)

Step-by-step explanation:

Set f(x)=0:

$f(x)=\frac{x^2+x-42}{x^2+3x-28}$

$0=\frac{x^2+x-42}{x^2+3x-28}$

$0=x^2+x-42$

$0=(x+7)(x-6)$

$x=-7$ or $x=6$

Now check both solutions:

$f(-7)=\frac{(-7)^2+(-7)-42}{(-7)^2+3(-7)-28}$

$f(-7)=\frac{49-7-42}{49-21-28}$

$f(-7)=\frac{42-42}{28-28}$

$f(-7)=\frac{0}{0}$

Therefore, $x\neq-7$ because there is a hole at $(-7,0)$ . The denominator, in addition, can never be 0, so the function is undefined for $x=-7$ .

$f(6)=\frac{(6)^2+(6)-42}{(6)^2+3(6)-28}$

$f(6)=\frac{36+6-42}{36+18-28}$

$f(6)=\frac{42-42}{54-28}$

$f(6)=\frac{0}{24}$

$f(6)=0$

Since $f(6)=0$ , then $x=6$ is the only zero of the function.
