Why might two students have different calculated areas when measuring the same rectangle?

Answer:

x = 6

Step-by-step explanation:

[tex]\frac{x}{3} -7=-5[/tex]

→ Add 7 to both sides

[tex]\frac{x}{3} =2[/tex]

→ Multiply both sides by 3

x = 6

Step-by-step explanation:

The order of operations is a rule that tells the correct sequence of steps for evaluating a math expression. We can remember the order using PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)

Answer:

39.

Step-by-step explanation:

I say good try to the first guy, but aye, it's not fully answering the question.

PEMDAS is the order you solve all of this in. Parenthesis (), Exponents (^), Multiplication (*), Division (/), Addition (+), and Subtraction (-).

We would solve (8-5) first for 3, since there is no sign between both three's, this will be multiplication.

Next is the exponent, 11^2 is 11*11, which is equal to 121.

121 - 3 * 3 * 7 - 19

Next up is Multiplication. 3 * 3 = 9, and 9 * 7 is 63.

Now our equation is 121 - 63 - 19. There is no Division or addition symbol, so we skip to Subtraction.

121 - 63 = 58, and 58 - 19 = 39.

Your Answer is 39.

The trail that is closest in length to 10.5 kilometers is Spruce Trail. option D

From the information given, we have that;

The closest in length would be the trail with the lowest difference;

Oak trail = 10.653 - 10. 5 = 0. 153

Maple Trail = 10.592 - 10. 5 = 0. 092

Pine Trail = 10.732 - 10. 5 = 0. 232

Spruce Trail = 10.484 - 10. 5 = -0. 016

Thus, the trail that is closest in length to 10.5 kilometers is Spruce Trail. option D

The statements are not valid syllogisms.

The term syllogism has to do with the reasoning in which a premise must lead to a conclusion. In other words, the conclusion must logically follow from the premise that has been given.

Let us now see if the statements follows the laws of syllogism;

Statement 1 - If you interview for a job, then you wear a suit.

Statement 2 - If you interview for a job, then you will update your resume.

Looking at these statements it is easy to see that they are not valid syllogism. This is because, not every job requires you to wear a suit for interview. You could have a CV that does not need to be updated and still use it for an interview.

Answer:

6 or 5

Step-by-step explanation:

The value of x is 8.366, y is 4.582 and z is 5.477.

Using Pythagoras theorem in both Triangle as

Triangle 1:

H² = P² + B²

z²= y² + 3²

z² = y² + 9

Triangle 2:

x² = y² + 7²

x² = y² + 49

and, x² = z² - 9 + 49

x² = z² + 40.............(1)

Now, In big Triangle

x² + z² = 10²

x² + z² = 100

Now, from equation (1) we get

z² + 40 + z² = 100

2z² = 60

z² = 30

z = 5.477

and, x²= 30+40 = 70

x= 8.366

and, y²= z² - 9

y² = 21

y= 4.582

Six times the cube of a number x

Given that

To find

So, according to the question

We have,

Now, for finding the six times of the cube of x, first we have to find the cube of x

                                = x¹ × x¹ × x¹

     ∵ The powers will be added when

                 [tex]a^{m}\times a^{n} = a^{m+n}[/tex]

     ∴                        = x⁽¹⁺¹⁺¹⁾

                                = x³

Now,

                                                          = 6 × (x³)

                                                          = 6x³

The six times of the cube of x =  6x³.

Step-by-step explanation:

The inequality to represent the temperatures at which the propane is safe to use is -40 < x < 120.

It is said that it is safe to use Propane between the temperatures of -40°C and 120°C.

We already know the use of an equality. It makes the values on both sides of it equivalent.

An inequality compares the values on both sides of it. It informs us which one is greater than or less than the other or if they are equal. That is, inequality has a possibility for equality too.

Here the minimum temperature at which propane is safe to use = -40°C

The maximum temperature at which Propane is safe to use = 120°C

We take a variable 'x' to denote the safe temperature of Propane.

Then according to the information, the inequality to represent the temperatures at which the propane is safe to use is,

            -40 < x < 120

Changing [f(-1) = 1] into coordinate points, we get (x₁, y₁) = (-1, 1),

Changing [f(2) = 7] into coordinate points, we get (x₂, y₂) = (2, 7),

Also, changing [f(1) = 1] into coordinate points, we get (x₃, y₃) = (1, 1),

And finally, changing [f(3) = 0] into coordinate points,

We get (x₄, y₄) = (3, 0).

As per question statement, we are provided with Four separate functions, as follows, [f(-1) = 1], [f(2) = 7], [f(1) = 1] and [f(3) = 0].

We are required to convert the above mentioned functions into coordinate points.

To solve this question, we need to know the standard form of conversion of functions into coordinate points, which goes as [y = f(x)], i.e., the ordinate is a function of the abscissa.

Thus comparing [y = f(x)] to [1 = f(-1)], we get (x, y) = (-1, 1).

Similarly, comparing [y = f(x)] to [7 = f(2)], we get (x, y) = (2, 7),

Comparing [y = f(x)] to [1 = f(-1)], we get (x, y) = (-1, 1),

And finally, comparing [y = f(x)] to [0 = f(3)], we get (x, y) = (3, 0).

Answer:

The length of the rectangle is 11 inches, and the width of the rectangle is 10 inches.

Step-by-step explanation:

Let l be the length of the longer side of the rectangle. Then the width of the rectangle is l-1 inches. Since the perimeter of the rectangle is 42 inches, we have:

2(l + l - 1) = 42

l + l - 1 = 21

2l = 22
