On solving the exponential function 16000 = P(0.9455)^t, the original value of the car is obtained as $18,930.
What is an exponential function?
The formula for an exponential function is f(x) = a^x, where x is a variable and a is a constant that serves as the function's base and must be bigger than 0.
The value of car in amount is A(t) = $16,000.
The rate of depreciation is x = 5.45% per year.
Rewriting the rate in exponential form - (1 - 0.0545) = 0.9455
The car is t = 3 years old.
Let P be the model that depicts the original cost of the car.
Then the exponential function will be -
16000 = P(0.9455)^t
Substituting the value of t in the equation -
16000 = P(0.9455)³
16000 = 0.8452P
P = 16000/0.8452486
P = 18,929.34 ≈ 18,930
Therefore, the original value of car was $18,930.

Which ordered pairs are solutions to the system of equations (-2,1.6)(0,3 3/5)(2,5 3/5) y=-0.5x+0.6
Y=x+3 3/5
The ordered pairs are solutions to the system of equations are (-2,1.6)
How to determine which ordered pairs are solutions to the system of equations?In order to determine which ordered pairs are solutions to the system of equations, you need to equate the two equations and solve for x:
y = -0.5x+0.6 and y= x+3 3/5
-0.5x+0.6 = x+3 3/5
-0.5x+0.6 = x+3.6
x+3.6 + 0.5x-0.6 = 0
1.5x + 3 = 0
1.5x = -3
x = -3/1.5
x = -2
y =-0.5x+0.6
y = -0.5(-2) + 0.6
y = 1.6
y = x + 3.6
y = -2 + 3.6
y = 1.6
Thus, the ordered pairs are (-2, 1.6)

Freddy had two of the brownies from a large pan. His friend said he ate 1/8 of the brownies in the pan. Tell why you agree or disagree.
I agree that Freddy ate 1 / 8 of the brownies in the pan because two brownies represents 1 / 8 of the brownies in the pan.
How to find the proportion of brownies eaten ?The large pan is said to have been used to make 16 brownies which means that if Freddy ate 2 brownies out of this, the proportion that he would have eaten of the cookies in the pan is:
= Number of brownies Freddy ate / Number of total brownies in the large pan
= 2 / 16
= 1 / 8
This therefore shows that Freddy's friend was right in saying that Freddy ate 1 / 8 of the brownies in the pan.

Therefore , the solution of the given problem of surface area comes out to be 0.2083 yard square.
Exactly what is surface area?A surface is a measurement of how much overall space an object's surface takes up. Surface area of a three-dimensional shape is determined by the total area of its surroundings. Surface area is the term used to describe a triangular shape's entire surface area. The particular area of each face on a cube with six square faces can be added up to determine the cube's surface area. Alternately, you can get the box's dimensions by using the following formula: Surface (SA) equals twice twice twice twice. A three-dimensional shape's surface area is calculated as the sum of all the space it occupies.
Here,
Given : width : 5/6 yard
and length = 1/4 yard

An animal shelter has 1008 cats, dogs and rabbits. The ratio of the number of dogs to the number of cats in the animal shelter is 3:7. The ratio of the number rabbits to the number of dogs is 2:5. How many rabbits are in the shelter
There are 108 rabbits in the shelter.
What is mean by Ratio?A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.
We have to given that;
An animal shelter has 1008 cats, dogs and rabbits.
And, The ratio of the number of dogs to the number of cats in the animal shelter is 3 : 7. The ratio of the number rabbits to the number of dogs is 2 : 5.
Here, The ratio of the number of dogs to the number of cats in the animal shelter is 3:7. The ratio of the number rabbits to the number of dogs is 2:5.
So, We can formulate;
Number of dogs : Number of cats = 3 : 7
Number of rabbits : Number of dogs = 2 : 5
Hence, We get;
Number of rabbits : Number of dogs : Number of cats = 6 : 15 : 35
Since, An animal shelter has 1008 cats, dogs and rabbits.
Hence, We get;
⇒ 6x + 15x + 35x = 1008
⇒ 56x = 1008
⇒ x = 18
Thus, Number of rabbits = 6x

Solving linear equations, mixture problem pls help
61.67 oz of the 55% acid solution and 33.33 oz of the 30% acid solution must be mixed to produce 100 ounces of a 43% acid solution.
This is a mixture problem that can be solved using algebra. We can set up a system of equations to represent the amount of each solution being used and the final acid concentration.
Let x be the amount of 55% acid solution and y be the amount of 30% acid solution used.
We can set up the following system of equations:
(55/100)x + (30/100)y = (43/100)(x + y) (Equation 1) represents the final acid concentration.
x + y = 100 (Equation 2) represents the total amount of solution mixed
We can solve for one variable in equation (1) by isolating it and substituting it into equation (2).
Solving for x in equation (1) we get: x = (100*43/100 - y30/100)/55/100
Substituting this value into equation (2) we get: (10043/100 - y30/100)/55/100 + y = 100
Solving for y we get: y = (100*100 - 100*43)/30 = 33.33 oz
And then substituting this value back into the equation x = (100*43/100 - y30/100)/55/100 we get x = 61.67 oz
So, 61.67 oz of the 55% acid solution and 33.33 oz of the 30% acid solution must be mixed to produce 100 ounces of a 43% acid solution.

When packed with toys and ready for shipment, both kinds of containers have the same number of toys and the same weight. What is the number of toys?
The number of toys is 5 in each container.
What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.
Let x be the number of toys in each container.
Weight of one toy car = 6 pounds
Weight of the container in which toy cars shipped = 5 pounds
Weight of x toy cars = 6x
Total weight of the container when toy cars are placed = 6x + 5
Weight of one toy truck = 3 pounds
Container weight = 20 pounds
Weight of x toy trucks = 3x
Total weight of the container when toy trucks are place = 3x + 20
Given that both containers have same weight.
6x + 5 = 3x + 20
6x - 3x = 20 - 5
