8x + 9 = 73 becauss ir is a square

8x = 64

x = 8

Answer:

Step-by-step explanation:

In square QRST, ST = 8x + 9 and QR = 73, what is x?

in the attached figure you can see that the measurement of ST and QR are the same, it is a square, therefore 4 equal sides, we can solve with an equation

8x + 9 = 73

8x = 73 - 9

8x = 64

x = 64 : 8

x = 8 units  (your answer)

-----------------------------

check

8 x 8 + 9 = 73

64 + 9 = 73

73 = 73

Expressions that represent the total cost of the field trip is

0.8{10x + 20y}.

A mathematical expression is made up of numbers, variables, and functions (such as addition, subtraction, multiplication or division etc.)

It is possible to compare expressions and phrases. In English, a phrase by itself could contain an action, but it doesn't constitute a full sentence.

As instances of expressions and how they connect to word phrases, consider the following:

Example: 3 + 7

The phrase "the product of three and seven"

Cost of Ticket for each student cost = $10

Cost of Ticket for each Teacher cost = $20

Let the total students be x

and, total number of teacher will be y

Total cost= 10x + 20y

As museum gives 20 % rebate for promotion

So, now total cost will be {10x + 20y} - 20/100 {10x + 20y}

So the required Expression would be 0.8{10x + 20y}.

Answer:

(-4, 8)

Step-by-step explanation:

y = -1.5x + 2

y = 5x + 28

y + 1.5x = 2

y - 5x = 28

6.5x = -26

x = -4

y = 5(-4) + 28

y = -20 + 28

y = 8

Answer:

y = -1/3x + 2

Step-by-step explanation:

Slope-intercept form of a linear equation is written as:

y = mx + b, where x and y are coordinates from one of the points on the line, m is the slope, and b is the y-intercept.

1. You'll first want to find the slope, m. Slope can be calculated from two points by using the equation (y1 - y2)/(x1 - x2). If you plug your two points into this equation for x and y (making sure that y1 and x1 are from the same point and y2 and x2 are from the other), you'll get,

(3 - 1)/(-3 - 3) = 2/-6 = -1/3

m = - 1/3

2. You can then plug your slope, m, into the slope-intercept form of the equation. Using one of your points (doesn't matter which, but I'll use (3,1)), you can solve for b, your y-intercept.

1 = -1/3(3) + b

1 = -1 + b

b = 2

3. Plug the variables into the equation.

For your final equation, plug the slope, m, and y-intercept, b, that you just found.

y = -1/3x + 2

The  number in which the value of the digit in the thousand place as  one-tenth the value of the digit in the ten-thousand place is  44,000.

In 44000, the value of each place is 1/10 the value of the place before it as you move to the right in the place value chart. As a result of moving one place to the left, the value of the digit in the number 44,000's ten thousands place is 10 times greater than that of the digit in the thousands place.

In mathematics, place value refers to a digit's location within a number. A number has a slot for each digit. The placement of each digit will be enlarged when we represent the number in general form.

These positions begin at the unit place, often known as the individual's position. Units, tens, hundreds, thousands, ten thousand, one hundred thousand, and so on are the place values of a number's digits from right to left.

Given that,
A mug is 1/3 full. The mug contains 3/4 of a cup of water. Find the capacity of the mug.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
As
1 / 3 of mug = 3 / 4 cups
1 of mug = 3/4 / [1/3]
1 of mug = 3×3 / 4
1 of mug = 9 / 4 cups or 2 1 / 4 cups

Trigonometry is a discipline of mathematics that examines certain functions of angles and how to use them in computations. There are six frequent uses for an angle in trigonometry. Sine, cosine, tangent, cotangent, secant, and cosecant.

The graph is sent as

Two point (-π/2 , 5) , (π/4 , -4)

amplitude is A = 9/2

Period  = π + π/2 = 3π/2

B = 2π/3π/2 = 4/3

Phase shift = - π/2  (π/2 to left)

Answer:

[tex]\huge{\boxed{\text{The height of the triangle is 6cm.}}}[/tex]

Step-by-step explanation:

This question requires us to use a system of equations.

The area of a triangle is (1/2) * (base) * (height).

Thus, if b = base, and h = height

[tex]\frac{1}{2} bh=36[/tex]

Additionally, from the problem, we know:

[tex]b=h+6[/tex]

Then, via substitution, we can get

[tex]\frac{1}{2} *(h+6)*h=36[/tex]

Then, simplify:

[tex]\frac{1}{2} h^2+3h=36[/tex]

[tex]\frac{1}{2} h^2+3h-36=0[/tex]

[tex](\frac{1}{2} h-3)(h+12)=0[/tex]

Thus, the height must equal either 6 or -12, and because height cannot intrinsically be negative, the height must be 6.

Hope it helps :) and let me know if you want me to elaborate.

The output values from the rule are -12, 2, 0, -6 and -10

From the question, we have the following parameters that can be used in our computation:

Rule = add -6

This means that

Output = Input - 6

Using the values in the question, we have

Output = -6 - 6 = -12

Output = 8 - 6 = 2

Output = 6 - 6 = 0

Output = 0 - 6 = -6

Output = -4 - 6 = -10

The above represent the output values

A technique called simple random sampling involves choosing a random group of individuals from a predetermined population.

A selection of participants from a population is chosen at random by the researcher using simple random sampling, a sort of probability sampling.

Every person in the population has the same chance of being chosen.

Then, data are gathered from as much of this randomly selected subgroup as possible.

A straightforward random sample, where each participant has an equal chance of being selected, selects a small, random portion of the entire population to represent the entire data set.

Using techniques like lotteries or random draws, researchers can generate a straightforward random sample.

It will take 6 months for Omari to finish paying off the monthly payment for the computer.

What is the monthly payment?

The amount paid each month to repay the loan over the course of the loan is known as the monthly payment. When a loan is taken out, not only the principal, or the original lent amount, but also the interest that accrues, must be repaid.

Given, the total price of the computer = $1,099

down payment = 20% of $1,099 = $219.8

The remaining amount = $1,099 - $219.8 = $879.2

monthly payments for the computer = $144

Then, the total months to pay = 879.2/144 = 6 months

Hence, it will take 6 months for Omari to finish paying off the monthly payment for the computer.
