Find the cost of the following item. A table marked up $45.00, selling for $189.95 4.22 144.95 234.95 8,357.80

Artemon [7]

Subtract:
189.95 - 45.00 = 144.95

Answer:

(a) x: Ferris wheel once; y: roller coaster once

Step-by-step explanation:

The coefficients of x and y are both 1 in the equation representing the statement ...

"if he rides them each once, it takes 14 minutes total."

That tells you that x and y represent the times for one ride.

__

The coefficient of x is 6 in the equation representing the statement ...

"he rides the Ferris wheel 6 times ..."

This tells you the variable x represents the Ferris wheel ride time. It is further confirmation that x represents the time for one ride.

Muli spent 3/10 of thus salary on flood and 2/3 on rent. He was left with sh. 2100.what was his salary?

Margarita [4]

Step-by-step explanation:

Let the total amount of salary be X, then

3/10X + 2/3X + amount left= his salary(X)

(9X + 20X)/ 30 + 2100 = X

29X/30 - X = -2100

(29X - 30X)/30 = -2100

by cross multiplying

-X = -2100×39

-X = -81900

divide both side by -1

X = 81900.

therefore his salary = 81900

Write a differential equation to represent each situation below. Do NOT solve them. a. A new technology is introduced into a com

Vladimir [108]

Answer:

a. x'(t) = kx(5000-x)

b. R_in = 7 lbs/min

R_out = 5c(t) lbs/min

c(t) = A(t)/(800 -3t) lbs/gal

A'(t) = R_in - R_out; A(0) = 200 lbs

Step-by-step explanation:

A. When proportionality is joint between x and y, the expression describing that is kxy, where k is the constant of proportionality. Here, the rate of change is jointly proportional to number who have adopted (x) and number of the community of 5000 who have not (5000-x). The corresponding equation is ...

x'(t) = kx·(5000-x)

We know the initial number of adopters must be greater than 0, or the equation's only solution would be x=0.

__

B. The rate of influx of salt is ...

R_in = (3.5 lbs/gal)×(2 gal/min) = 7 lbs/min

The number of gallons in the tank at time t is ...

v = 800 gal + (2 gal/min - 5 gal/min)(t min) = (800 -3t) gal

For amount of salt A(t) pounds, the concentration c(t) will be ...

c(t) = A(t)/v = A(t)/(800 -3t) . . . . lbs/gal

The outflow rate will be the product of outflow volume and concentration:

R_out = (c(t) lbs/gal)(5 gal/min) = 5c(t) lbs/min

And the differential equation for A(t) is ...

A'(t) = R_in -R_out . . . with initial condition A(0) = 200 lbs.

__

When you go to solve the equation for A'(t), it will need to be cast in terms of A(t):

A'(t) = 7 -5A(t)/(800 -3t)
