Kate is 17 years old, and Victor is 12 years younger. In how many years will Kate be twice as old as Victor?

9966 [12]

Answer:

In 7 years

Step-by-step explanation:

Let

n ----> the number of years

x -----> Kate's age

y ----> Victor's age

we know that

$(x+n)=2(y+n)$

we have

$x=17\\y=17-12=5\\$

Victor's age is 5

substitute the given values

$(17+n)=2(5+n)$

Solve for n

$17+n=10+2n$

$2n-n=17-10$

$n=7$

Verify

In 7 years

Kate's age is 17+7=24

Victor's age is 5+7=12

24=2(12)

Kate is twice as old as Victor

tester [92]

Answer:

En el curso anterior había 430 alumnos.

Step-by-step explanation:

El curso tiene 473 alumnos. Nos dicen que respecto al curso anterior se ha producido un aumento de inscripciones del 10 %. Entonces, siendo x la cantidad de alumnos que había en el curso anterior, se puede plantear la ecuación:

x + 0.1*x= 473

Resolviendo se obtiene:

1.1*x=473

x= 473 ÷1.1

x= 430

En el curso anterior había 430 alumnos.

The quantity of Sensitech laser gaming mice demanded each month is related to the unit price by the equation p = 480.03x2 + 1 (0

stich3 [128]

Answer: a) $p=480.03x^2+1$ , b) $R'(x)=1440.09x^2+1$ c) $5761.36.

Step-by-step explanation:

Since we have given that

Unit price is expressed as

$p=480.03x^2+1$

Let x be the number of units of a thousands.

So, Revenue function is given by

$R(x)=px\\\\R(x)=x(480.03x^2+1)\\\\R(x)=480.03x^3+x$

.(b) Find the marginal revenue function R'..

Marginal revenue function becomes,

$R'(x)=3\times 480.03x^2+1\\\\R'(x)=1440.09x^2+1$

$R'(2)=1440.09(2)^2+1\\\\R'(2)=5760.36+1\\\\R'(2)=5761.36$

Hence, a) $p=480.03x^2+1$ , b) $R'(x)=1440.09x^2+1$ c) $5761.36.
