The equation which is true is 6 ÷ 100 = 0.06

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Answer:

256 text

Step-by-step explanation:

Let's call the number of text messages Sarah sends in a month as "x".
So, the total cost of the text messages is $0.25 * x.

The total cost of the phone service and text messages is $35 + $0.25 * x = $99.

So, $35 + $0.25 * x = $99.

Subtracting $35 from both sides, we have:$0.25 * x = $99 - $35 = $64

Dividing both sides by $0.25, we have:x = 256

So, Sarah sent 256 text messages in one month.

The value of the equation is A = ( 6x - 9y ) / ( 3 + 2y )

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

A = ( 12x - 18y ) / ( 6 + 4y )

On simplifying the equation , we get

Taking the common factor as 6 in the numerator , we get

A = 6 ( 2x - 3y ) / ( 6 + 4y )

Taking the common factor as 2 in the denominator , we get

A = ( 6/2 ) ( 2x - 3y ) / ( 3 + 2y )

Answer:

30.

Step-by-step explanation:

We can write an equation for the number of gallons of water in the bathtub using the rate of change (drainage) and the elapsed time. Let y be the number of gallons of water in the tub after t minutes. Then, the equation can be written as:

y = 42 - (drainage rate) * t

Since we know that after 2 minutes, the tub holds 30 gallons of water, we can use this information to solve for the drainage rate:

30 = 42 - (drainage rate) * 2

12 = (drainage rate) * 2

drainage rate = 6 gallons per minute

Substituting this value into the original equation, we get:

y = 42 - 6t

So, the equation that represents the number of gallons of water in the tub after 2 minutes is:

y = 42 - 6 * 2 = 42 - 12 = 30.

Answer:

The equation representing the number of gallons of water in the tub after t minutes can be represented by a linear function y = mx + b, where y is the number of gallons of water, x is the number of minutes, m is the rate of change (or the slope) and b is the y-intercept.

Since the bathtub is draining at a constant rate, the slope (m) can be found by finding the difference between the initial number of gallons of water (42) and the number of gallons after 2 minutes (30), and dividing by the difference in time (2 minutes):

m = (42 - 30) / 2 = 6 gallons per minute

The y-intercept (b) can be found using the initial conditions of the problem, when t = 0:

b = 42 - (6 * 0) = 42

Therefore, the equation representing the number of gallons of water in the tub after t minutes can be written as:

y = 6t + 42

So, after 2 minutes, y = 6 * 2 + 42 = 54 gallons of water.

If the measure of ABC = 170°, the measure of QRS is equal to 10°.

In Mathematics, a supplementary angle simply refers to two (2) angles or arc whose sum is equal to 180 degrees.

Additionally, the sum of all of the angles on a straight line is always equal to 180 degrees. In this scenario, we can logically deduce that the sum of angles ABC and QRS are supplementary angles:

m∠ABC + m∠QRS = 180°

Substituting the given parameters into the formula, we have the following;

170° + m∠QRS = 180°

m∠QRS = 180° - 170°

m∠QRS = 10°

Chords AB and CD intersect at E and AE= EB is Semi circle is drawn with diameter CD. EF perpendicular to CD meet this semi circle at F then AE= EF

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

Let M be the midpoint of AB, so EM is perpendicular to AB.

Since OF is a diameter of the circle, angle EOF is a right angle.

Triangles EOF and EMA are similar, since they both have a right angle and angle EFM is congruent to angle EAM, being alternate interior angles of parallel lines.

The corresponding sides are proportional:

EF / EA = EO / EM.

EM is half the length of AB, which is the diameter of the semicircle,

EO must be equal to the radius of the semicircle.

Therefore, we have EF / EA = radius / (diameter / 2) = 2 / 2 = 1,

EF = EA.

Answer: C= 24-4t

Step-by-step explanation: Since four were eaten each dat the blue is getting lower, use -4t to represent it. 24 is the total amount gotten by substitution.

Bob gave the cashier $15.26 for the bag of beans.

To find the value of x, we need to subtract the cost of the beans from the total amount given to the cashier. The cost of the beans is $2.37, and the change received is $17.63.

Therefore, the value of x can be calculated as:

x = Total amount given to the cashier - Cost of the beans

x = $17.63 - $2.37

x = $15.26

A cashier is an employee who works in a retail or service industry, responsible for handling cash, credit card payments, and providing customer service. They are often the first and last point of contact for customers in a business. Cashiers use a cash register or computer system to record transactions, and must be able to accurately count money, make change, and reconcile the cash drawer at the end of their shift.

There are 4,608 different ways that the class can elect a president, vice president, and secretary.

To find the number of different ways that a class of 18 students can elect a president, vice president, and secretary, we will use the formula for permutations, which is given by -

nPk = n! / (n - k)!

where n is the total number of items and k is the number of items to be selected in a specific order.

In this case, we are given n = 18 students and k = 3 positions.

Thus, the number of different ways to elect a president, vice president, and secretary will be -

18P3 = 18! / (18 - 3)! = 18! / 15! = 18 x 17 x 16 = 4,608

The estimated percentage of states with an average per capita income greater than 32.5 k  is:we need to use the ogive (cumulative frequency curve) to determine the percentage of states with an average per capita income greater than 32.5k.

Assuming that the ogive is a continuous curve, we can estimate the percentage by finding the value on the horizontal axis corresponding to the 50% mark on the vertical axis, and then subtracting it from 100%. From the graph, we can see that the 50% mark corresponds to a value of around 30 k, which is between the values for Oklahoma and Pennsylvania. To get a more accurate estimate, we can use linear interpolation between these two data points.

Let's assume that the values for Oklahoma and Pennsylvania are

(x₁,y₁) = (25k,40%) and (x₂,y₂) = (35k,60%)

respectively. Then the equation of the straight line connecting these two points is:

(y-y₁) =(y₂-y₁) / (x₂-x₁) * (x-x₁)

Substituting in the values gives:

y - 40 = (0.6 - 0.4)/(35 - 25) * (x - 25)

y - 40 = 0.02(x - 25)

y = 0.02x - 0.5

To find the value of x that corresponds to the 50% mark, we can set y = 50% and solve for x:

50 = 0.02x - 0.5

0.02x = 50.5

x = 2525

So the estimated value for x is 25.25k. Therefore, the estimated percentage of states with an average per capita income greater than 32.5k is:

scss

Copy code

100% - 40% - (10% * (32.5 - 25.25)/(30 - 25))
