Answer:

Julio terminará pagando $3285.25 por el celular.

Step-by-step explanation:

Con la información proporcionada, puedes encontrar cuánto terminará pagando Julio por el celular calculando el 15% del precio del celular dado que ese sería el valor del descuento y luego, tienes que restar ese valor del precio del celular:

$3865*15%=$579.75

$3865-$579.75=$3285.25

De acuerdo a esto, la respuesta es que Julio terminará pagando $3285.25 por el celular.

What is the equation of the line containing the points (3, 1), (9, 3), and (27, 9)?
lutik1710 [3]

From the given points that are (3,1),(9,3),(27,9), we can say that x is three times of y. That is

x= 3y

And we need to solve for y. For that, we need to get rid of 3 from the right side by dividing both sides by 3 . And on doing so , we will get

\frac{x}{3} = \frac{3y}{3}

\frac{x}{3}=y

or

y=\frac{x}{3}

For each mile Jason runs Megan runes 1/4 mile farther if Jason ran 6 miles how far did Magen run ?
fenix001 [56]
Let, Jason = J and M = Megan

M = J(1 + 1/4) 

So putting 6 where J is and solving:
<em>M = 6(1 + 1/4)
</em><em>M= 7.5</em>

When Jason runs 6 miles Megan runs 7.5

A tank contains 30 lb of salt dissolved in 300 gallons of water. a brine solution is pumped into the tank at a rate of 3 gal/min
sesenic [268]
A'(t)=(\text{flow rate in})(\text{inflow concentration})-(\text{flow rate out})(\text{outflow concentration})
\implies A'(t)=\dfrac{3\text{ gal}}{1\text{ min}}\cdot\left(2+\sin\dfrac t4\right)\dfrac{\text{lb}}{\text{gal}}-\dfrac{3\text{ gal}}{1\text{ min}}\cdot\dfrac{A(t)\text{ lb}}{300+(3-3)t\text{ gal}}
A'(t)+\dfrac1{100}A(t)=6+3\sin\dfrac t4

We're given that A(0)=30. Multiply both sides by the integrating factor e^{t/100}, then

e^{t/100}A'(t)+\dfrac1{100}e^{t/100}A(t)=6e^{t/100}+3e^{t/100}\sin\dfrac t4
\left(e^{t/100}A(t)\right)'=6e^{t/100}+3e^{t/100}\sin\dfrac t4
e^{t/100}A(t)=600e^{t/100}-\dfrac{150}{313}e^{t/100}\left(25\cos\dfrac t4-\sin\dfrac t4\right)+C
A(t)=600-\dfrac{150}{313}\left(25\cos\dfrac t4-\sin\dfrac t4\right)+Ce^{-t/100}

Given that A(0)=30, we have

30=600-\dfrac{150}{313}\cdot25+C\implies C=-\dfrac{174660}{313}\approx-558.02

so the amount of salt in the tank at time t is

A(t)\approx600-\dfrac{150}{313}\left(25\cos\dfrac t4-\sin\dfrac t4\right)-558.02e^{-t/100}

Use a conversion factor to convert 872 meters (m) to millimeters (mm).
dybincka [34]

Hey there! I'm happy to help!

There are 1,000 millimetres in 1 meter. So, we multiply by 1,000.

872(1000)=872,000

There are 872,000 mm in 872 m.

Have a wonderful day! :D
