MODELING REAL LIFE The table shows the profit y for recycling x pounds of aluminum. Find the profit for recycling 75 pounds of aluminum. Aluminum (lb), x 10 20 30 40 Profit, y $4.50 $9.00 $13.50 $18.00​

Answers

Answer: 33.75

Step-by-step explanation:

It’s right

There is a profit of $33.75 for recycling 75 pounds of aluminum.

What is Function?

A function is a relation from a set to another set such that element in the first set only maps to one element in the other set.

A function f from a set A to a set B can be represented as f : A → B

We have,

Profit for recycling 10 lb Aluminum = 10/10 × 4.5 = 4.50

Profit for recycling 20 lb Aluminum = 20/10 × 4.5 = 9.00

and so on

Therefore, we can write this as a function.

f(x) = [tex]\frac{x}{10}[/tex] × 4.5

We have to find the profit for recycling 75 pounds of aluminum.

f(75) =  [tex]\frac{75}{10}[/tex] × 4.5

       = 7.5 × 4.5

       = 33.75

Hence the profit for recycling 75 pounds of aluminum is $33.75.

The phrase represents the expression 7x + 2 is the number multiplied by seven then added to two, So Option D is correct

What are expressions?

An expression is a sentence with at least two numbers or variables having mathematical operation. Math operations can be addition, subtraction, multiplication, division.

For example, 2x+3

Given that,

An expression,7x + 2

here, 7 is coefficient

x is variable

And then in 7x, constant number 2 is added

So it can be state that a number multiplied by seven then added to two

So, the statement is 7  multiplied in number then 2 is added

Jenny selects a box of cereal for her family at the supermarket. Across town, Chase also happens to pick out a box of cereal for his own family. Are these two events dependent or independent?

Answers

Answer:

Independent

Step-by-step explanation:

In clear and simple terms, Events A and B are sid to be independent if the occurrence of event A and event B can occur simultaneously, that is the occurrence of A does not affect or stop the occurrence of B at the time.

The events being compared can happen concurrently with Jenny and chase both making selection for their respective families. However, events which cannot occur together are called mutually exclusive events such as obtaining a head and tail from a single coin toss, this events cannot happen together and are thus not independent.

A right triangle has legs with lengths of 6in and 8in. What is the length of the hypotenuse

Answers

You require the Pythagorean Theorem: in a right triangle the sum of the squares of the legs equals the square of the hypotenuse.
In this case 6^2 + 8^2 = 36 + 64 = 100 = 10^2, i.e. the hypotenuse is 10.
Please note that a so-called 3-4-5 right triangle is the smallest right triangle which has integer sides...and of course, a 6-8-10 triangle like this one is simply a magnification of the smaller, i.e. a so-called similar triangle.

Answer: 10

Step-by-step explanation:

the formula is √a^2+b^2=c^2

so your equation should look like this √6^2+8^2=c^2

6·6=36

8·8=64

√36+64

√100=10

the hypotenuse or c^2 is 10

A triangle has a base of 10 centimeters and a height of 12 centimeters. A rectangle has a base of 10 centimeters and a height of 12 centimeters.
What are the areas of the figures?



The area of the triangle is
___ cm2.


The area of the rectangle is
___ cm2.

Answers

The area of the triangle is

60 cm2.

The area of the rectangle is

240 cm2.

In a two-dimensional plane, an area of triangle is equal to the sum of the areas of its three sides.

To calculate a rectangle's area, count the number of square units that fit within the rectangle's perimeter.

Area of triangle = h x b / 2

Given

h = 12

b =10

hence

A= h x b / 2

  = 12 x 10 / 2

  = 120 / 2

  = 60 cm2

Area of rectangle = l x b

Given

l = 12

b = 10

hence

area of rectangle  = l x b

                          = 12 x 10

                         = 120 cm2

The bronx zoo opened at 9.00 am. In the first hour 280 people purchased admission tickets. In the second hour 25 percent more people purchased admission people than the first hour . Each ticket cost 16.25. What was the total amount of money paid for all the tickets purchased in the first two hours

Answers

Answer:

Total amount paid for tickets in the two hours =  $10,237.50

Step-by-step explanation:

Step 1

Ist Hour, 280 tickets were sold at the cost of $16.25

Amount of money made in the first hour= Number of people who purchased ticket  x price of a ticket

=280 x 16.25 =$4,550

2nd Hour, 25 % more people purchased ,

which means the total number of people who purchased tickets =

1.25 x 280= 350

Amount of money made in second hour =  Number of people who purchased ticket  x price of a ticket 350 x 16.25 =$5,687.5

Step 2

Total amount paid for tickets in the two hours =  Amount of money made in the first hour +Amount of money made in second hour

=$4,550+ $5,687.5

=$10,237.50

A square is cut diagonally into two equal parts. If each part has an area of 50 cm2, then what is the perimeter of each part?

Answers

Answer:

30cm

Step-by-step explanation:

Given data

When are square is cut diagonally into two parts

The resulting shape is a triangle

hence the area of the square = 50+50 = 100cm^2

The length of each side of the square = √100= 10cm

likewise the diagonal of the square = 10cm

Hence the perimeter of the resulting triangle= 10+10+10= 30cm
