The equation shows that the number of toys that must be bought for them to have equal profit will be 212 toys.

<h3>How to calculate the value?</h3>

From the information, it should be noted that the equation that can be used to represent the information about Jaclyn company will be:

= 2125 + (49.99 × x)

= 2125 + 49.99x

The equation that can be used to represent the information about Richie company will be:

= (39.95 × x)

= 39.95x

Therefore, we will equate both equations:

2125 + 49.99x = 39.95x

49.99x - 39.95x =2125

10.04x = 2125

x = 212

Therefore, the number of toys that must be bought for them to have equal profit will be 212 toys.

kyle works at a donut factory where a 10-oz cup of coffee costs 95 cents, a 14-oz cup costs $1.15, and a 20-oz cup costs $1.50.

8_murik_8 [283]

Answer:

The number of a 10-oz cup of coffee was 6

The number of a 14-oz cup of coffee was 6

The number of a 20-oz cup of coffee was 5

Step-by-step explanation:

Let

x ----> the number of a 10-oz cup of coffee

y ----> the number of a 14-oz cup of coffee

z ----> the number of a 20-oz cup of coffee

we know that

$x+y+z=17$ -----> equation A

$10x+14y+20z=244$ ----> equation B

$0.95x+1.15y+1.50z=20.10$ ----> equation C

Using a equation System Solver (Wolfram Alpha)

The solution is

x=6, y=6, z=5

see the attached figure

therefore

The number of a 10-oz cup of coffee was 6

The number of a 14-oz cup of coffee was 6

The number of a 20-oz cup of coffee was 5

Se ha determinado que la población P (t) de una colonia de bacterias, t horas después de iniciar la observación, tiene una razón

maxonik [38]

Answer:

La población 20 horas después será de 321,161 bacterias.

Step-by-step explanation:

t horas después de iniciar la observación, tiene una razón de cambio de P'(t) = 350 e0.18t + 220 e-0.3t.

Esto implica que la población después de t horas viene dada por:

$P(t) = \int P^{\prime}(t) dt$

$P(t) = \int (350e^{0.18t} + 220e^{-0.3t}) dt$

Teniendo en cuenta que

$\int e^{at} dt = \frac{1}{a}e^{at}$

$P(t) = \int (350e^{0.18t} + 220e^{-0.3t}) dt$

$P(t) = \frac{350}{0.18}e^{0.18t} - \frac{220}{0.3}e^{-0.3t} + K$

En que k es la población inicial, o sea, $K = 250000$ . Entonces

$P(t) = 1944.44e^{0.18t} -733.33e^{-0.3t} + 250000$

¿Cuál será la población 20 horas después?

Esto eres P(20). Entonces:

$P(20) = 1944.44e^{0.18*20} -733.33e^{-0.3*20} + 250000 = 321161$

La población 20 horas después será de 321,161 bacterias.
