The inequality -15 <-6 is given. Perform the given operation, then write a true
inequality to match the result.
Subtract 12 from both sides of the inequality.

Answer:

1.5 or 3/2

Step-by-step explanation:

The scale factor is the factor by which the side lengths of the original shape are multiplied by. In this case, the original shape had side lengths 17 and was multiplied by [tex]x[/tex] to get the scaled shape.

Now we get the equation [tex]17\cdot x=51/2[/tex]. Solving, we get x=1.5

Answer: The Answer would be -49/8d -1/10

Step-by-step explanation: I got it right on the test

have a good day

The answer for the given expression is -49d/8 - 1/10. Thus, the correct option is option A.

The expression can be solved by simple arithmetic operation.

(-3 1d/4 + 3/5) - (2 7d/8 + 7/10)

In the next step simplify the terms and open brackets.

-13d/4 + 3/5 -23d/8 - 7/10

Taking the like terms together.

-13d/4 - 23d/8 + 3/5 - 7/10

Solving the terms by taking L.C.M.

(-104d-92d/32) + (30-35/50)

-196d/32 - 5/50

Simplifying the terms.

-49d/8 - 1/10.

We can tell if a triangle can exist based on the relationship between the side lengths.

Side Length Relationships

For a triangle to really exist, the sum of the smaller legs must be greater than the length of the longest leg. This can be expressed with the inequality a + b > c, where a and b are the shorter legs.

Now, we can plug the values we are given into this inequality.

Since the inequality is true, this triangle does exist.

Other Examples

One of the most important things to remember is that the sum of the shorter legs must be greater than, not equal to, the longest leg. So take the sides 4, 6, and 10.

This statement is not true. 10 is not greater than 10; they are equal. Thus, these sides cannot make a triangle.

Additionally, if the 3 numbers are Pythagorean triples, then it will be a right triangle. For example, the sides 5, 12, and 13 will create a right triangle.

The height of the rectangular pyramid tent's center pole = 5.5 feet.

Volume of rectangular pyramid = 1/3(length)(width)(height).

Given the following:

Substitute

88 = 1/3(8)(6)(height)

88 = 16(height)

88/16 = height

5.5 = height

Therefore, the height of the rectangular pyramid tent's center pole = 5.5 feet.

The proof for the decimal expansion d₁d₂d₃d₄.... is evaluated.

A number's decimal expansion is its base-10 representation (i.e., in the decimal system).

Now, as per the given question;

We focus on non negative decimal expansions as well as nonnegative real numbers. Every nonnegative decimal expansion, in our opinion, is short form for the limit of a constrained increasing sequential manner of real numbers.

Assume we're given a decimal expansion K. d₁d₂d₃d₄.... where K is a non-negative integer and each value of dj belongs to {0,1,2,3,4,5,6,7,8,9}.

Then Sn is defined as the increasing sequential of real numbers and Sn is also restrained by (sn < k + 1) .

Using Theorem; converges to a real number, which we usually write as K. d₁d₂d₃d₄....

[tex]\lim _{n \rightarrow \infty}\left(3+\frac{3}{10}+\frac{3}{10^2}+\cdots+\frac{3}{10^n}\right)[/tex]

The slope is 4 and point on the line is origin (0,0).

A line is a straight one-dimensional figure having no thickness and extending infinitely in both directions. A line is made of a set of points which is extended in opposite directions infinitely. It is determined by two points in a two-dimensional plane. The two points which lie on the same line are said to be collinear points.

Given:

The equation of the line is

y+4=4(x-2)

We have to find the slope and point on the line.

y+4=4(x-2)

y+4=4x-8

Substract 4 from both sides we get,

y=4x-12

Since the equation now is in y = mx + b form, we can identify the slope m=4 and the y-intercept b=-12 and point on the line origin (0,0).

Therefore, the slope is 4 and point on the line is origin (0,0).

For the given expression;

Step-by-step explanation:

Extreme values have little impact on the median and quantiles because they all come inside the middle half of the data.

Calculation:

Let’s assume the 24 students in the room range in age from 185, 185, 186, 186,.... 195, 195, 196, 196 months.

The total of x2 is 871252.

The sum of x is 4572.

The mean is 190.5 (4572/24).

The median, which lies between positions 12 and 13, is 190.5.

Standard deviation is (871252/24 -190.52)^0.5 = 3.45

Halfway between the( 18th and 19th)- (6th and 7th)interquartile range

= 6 (193.5 - 187.5).

Include his age of 716 months in the calculations as the teacher now.

Total x2 = 1383908

Total x = 5288

Mean (5288/25) = 211.52

Median (13th) = 191

Standard Deviation is (1383908/25 - 211.522)^0.5 = 103.03

Interquartile range (7th minus 19th) is 194 - 188 = 6

Therefore the mean has changed by 21.02 after the addition of a piece of data that is vastly different from the rest, yet the median has changed by only 0.5.

The interquartile range has remained constant, whereas the standard deviation has increased by over 100 and by a factor of approximately 30.

Step-by-step explanation:

Thomas bought 6 plastic cups and 6 glass cups.

For given question,

Let a be the number of glass cups and b be the number of plastic cups.

Thomas bought 12 glass cups and plastic cups.

So, we get an equation

a + b = 12                        .................(1)

The glass cups cost $3.25 and plastic cups cost $2.75

Thomas spent a total of $36

From this information we get equation,

3.25 a + 2.75 b = 36         ............(2)

We have a system of equations.

From equation (1),

a = 12 - b                  .............(3)

Substitute above value of a in equation (2)

3.25 (12 - b) + 2.75 b = 36

39 - 3.25 b + 2.75 b = 36

39 - 0.5 b = 36

-0.5 b = -3

b = 6

This means, Thomas bought 6 plastic cups.

Substitute above value of b in equation (3)

So, a = 12 - 6

a = 6

Thomas bought 6 glass cups.

Therefore, Thomas bought 6 plastic cups and 6 glass cups.

Compare both shapes

Find out the length of the red line through Pythagoras theorem

a² + b² = c²

9² + b² = 15²

15²- 9² = b²

144 = b²

√144 = b

b = 12

Red line is 12 and the other length of one side of the triangle is x - 9

The hypotenuse of the other triangle will be equal to:

a² + b² = c²

12² + (x-9)² = c²

144 + x² - 9x -9x + 81 = c²

x² - 18x + 225 = c²

THE HYPOTENUSE OF THE 2ND TRIANGLE = x² - 18x + 225

NOW COMPARE BOTH TRIANGLES

x² - 18x + 225 :    15

       x - 9        :     9

Cross multiply

9(x² - 18x + 225) = 15(x - 9)

9x² - 162x + 2025 = 15x - 135

9x² - 162x - 15x + 2025 + 135 = 0

9x² - 177x + 2160 = 0

Now use the quadratic equation

x = (-b +- √b² - 4ac)/2a

a = 9

b = -177

c = 2160

x = (-(-177) +- √(-177)² - 4(9)(2160))/(2×9)

x = (177 +- √31329 - 77760)/(18)

x = (177 +- √-46431)/18
