Step-by-step explanation:

Hello! This is actually easier than you think! All you have to do is make what is already written as a proportion.  You don't have to solve anything! You are already given one number which represents the first thing you were told, 4 cups of rice.  For 4 cups of rice, 5 cups of water are needed.  As a proportion, you would write 4/5.  For the second proportion you would write the 16 cups of rice per 20 cups of water as 16/20.  The answer is 4/5 = 16/20.  Hope this helps with your homework!

The total amount of money which Trevor's family spend, in total, on shower water in the past month is equal to $86.4.

Based on the information provided about the house Trevor's family lives in, we have the following important parameters;

Next, we would calculate the total volume of water that is used to shower by six (6) persons as follows;

Total volume of water for 6 persons = 72 × 6

Total volume of water for 6 persons = 432 liters.

Furthermore, the total amount of money that was spent on shower water by Trevor's family in the previous month is given by;

Total amount of money = total volume of water used for shower × cost per liter of water

Total amount of money = 432 × 0.2

What is Rectangle?

The internal angles of a rectangle, which has four sides, are all exactly 90 degrees. At each corner or vertex, the two sides come together at a straight angle. The rectangle differs from a square because its two opposite sides are of equal length.

The whole distance that a rectangle's boundaries, or its sides, the cover is known as its perimeter. Given that a rectangle has four sides, the perimeter of the rectangle will be equal to the sum of its four sides. Since a rectangle's perimeter is a linear measurement, the unit will be in meters, centimeters, inches, feet, etc.

Perimeter of a rectangle = 2(Length + Width) square units

Area of a rectangle = Length × Width = a × b

In our question, it is given that the Perimeter is 999 ft.

Putting this in our Perimeter formula.

2(Length + width) = 999

Length + width = 499.5

Therefore our possible measurement of Length and Width will be 249.75 feet each.

There are 128 three digit numbers divisible by 7

We know that the divisibility rule of 7 is:

If the difference between twice the unit digit of the given number and the remaining part of the given number is multiple of 7 or the difference is 0, then the number is divisible by 7.

the range of three digit numbers is 100 to 999

The first three-digit number divisible by 7 is 105 and the last  three-digit number divisible by 7 is 994.

The numbers divisible by 7 must be: 105, 112, . . ., 994

We can observe that the above series represents the arithmetic progression with common difference d = 7, the first term a = 105 and the last term a_n = 994

We know that the formula for the n-th term of AP is:

a_n = a1 + (n - 1)d

994 = 105 + (n - 1)7

7n - 7 = 889

7n = 889 + 7

7n = 896

n = 128

The product of power principle tells us that when we are multiplying powers with the same bases, we add the exponents.

The range of the function f(x) = logbx is {y | y > 0}.

The range of the function f(x) = logbx is the set of all possible output values (or "y-values") that the function can produce. In this case, the function is a logarithm in base b, where b is a positive real number, and x is the argument of the logarithm, also a positive real number.

For a logarithm function, the range is all real numbers y such that y > 0, because the logarithm of a positive number is always positive. The domain of the function is all positive real numbers x because the logarithm of a positive number is always defined.

So, the range of the function f(x) = logbx is {y | y > 0}.

It's worth noting that the logarithm function is defined only for positive real numbers x, hence the domain of this function is x > 0 and the range is y > 0.

Also, the base of the logarithm b is a positive real number, different than 1, this ensures that the logarithm function is defined for all x > 0, for b = 1 it would not be defined for x = 1.

The number of commercials in which Avery's songs were played is 5.

The number of movies in which Avery's songs were played is 5.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 9 is an equation.

We have,

The number of times the song played in commercials = x

The number of times the song played in a movie = y

Now,

Avery will earn $40 every time one of her songs is played in a commercial and earn $140 every time one of her songs is played in a movie.

We can make two equations.

x + y = 7 ____(1)

x = 7 - y _____(2)

40x + 140y = 480 _____(3)

Substituting (2) in (3) we get,

40(7 - y) + 140y = 480

280 - 40y + 140y = 480

100y = 480 - 280

100y = 200

y = 2

x = 7 - 2

Given:

Raul crosses Main Street when he walks home from school.

The graph of the function d(t)=4I(t-0.75)I shows Raul's distance, in miles, from Main Street after t hours.
