The discount as a percentage is 13.8%

The price of a picnic basket is marked as $31

The original price is $36

The discount percentage can be calculated as follows

36-31/36 × 100

= 5/36 × 100

= 0.138× 100

= 13.8%

Hence the percentage discount is 13.8%

A period on a graph function is the distance between two repeating points.

The graph repeats itself as it advances along the x-axis, as you can see.

Periods are the cycles of this predictable repetition. Every 6.28 units, or 2 pi radians, this graph repeats.

The equation is F(t) = 20 cos (2π/5)t

The amplitude of the equation is 20 and the graph makes 2π/5 oscillations at every t seconds

The ordered pairs are solutions to the system of equations are (-2,1.6)

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)

Answer: The phrase "5 times a number, divided by 6" can be translated into the algebraic expression:

(5/6)x

This expression represents "5 times a number, divided by 6", where x is the unknown number.

Step-by-step explanation:

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.

The complete function table using the defined function rule is as shown below.

We are given the function rule as;

h(x) = 2x - 3

From the function table attached, we will need to find the value of the function h(x) at x = -3, -2, 1, 3, 5

Thus;

Plugging in the value of -3 for x in the given function rule gives us the output as;

h(-3) = 2(-3) - 3

h(-3) = -9

Plugging in the value of -2 for x in the given function rule gives us the output as;

h(-2) = 2(-2) - 3

h(-2) = -7

Plugging in the value of 1 for x in the given function rule gives us the output as;

h(1) = 2(1) - 3

h(1) = -1

Plugging in the value of 3 for x in the given function rule gives us the output as;

h(3) = 2(3) - 3

h(3) = 3

Plugging in the value of 5 for x in the given function rule gives us the output as;

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.

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

The number of toys is 5 in each container.

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

3x = 15

x = 5

There are 108 rabbits in the shelter.

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

                                      = 6 × 18

Therefore , the solution of the given problem of surface area comes out to be  0.2083 yard square.

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

To find the area = length * width

=> area = 5/6 * 1/4

The probability of getting two spades when two cards are drawn from the deck is 1/17.

Probability branch of mathematics the deal with the likewood of an event occouring. It is the measure of how likely it is something will happen or be the case. Probabilities expressed as a number between zero and one 00 indicates impossibility and one indicus certainity. Probability can be used to calculate the chances of certain outcome based on a state condition or data. Probability can also be used to make decision and prediction about the future.

The probability of getting two spades when two cards are drawn from a shuffled deck of cards is 3/52 x 2/51, or 1/17.

This is because there is a 3/52 chance of getting the first spade and a 2/51 chance of getting the second spade (since there is one less card in the deck).

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.
