Answer:

-x-12

Step-by-step explanation:

Given:

[tex]\displaystyle \large{|x-(-12)| \quad (x < -12)}[/tex]

Simplify:

We know that negative times negative equals positive, therefore:

[tex]\displaystyle \large{|x+12| \quad (x < -12)}[/tex]

Modulus Property:

[tex]\displaystyle \large{|x+a| = \begin{cases} x+a \quad (x \geq -a) \\ -x-a \quad (x < -a) \end{cases}}[/tex]

Therefore, since given interval is x < -12:

[tex]\displaystyle \large{|x+12| \quad (x < -12) = -x-12}[/tex]

Hence, simplified expression is -x - 12

Answer:

-x-12

Answer:

78 yards squared.

Step-by-step explanation:

Step 1: 5 x 6.5 divided by 2. We can save time and do this twice, since its equal to the trinagle of on the other side.

Step 2: 6.5 x 7

Step 3: Add your totals for your final answer in yards squared. (78)

Answer:

Congruent Sides- Rectangle, Rhombus, Square

Right Angles- Rectangle, Square

Both- Rectangle, Square

Step-by-step explanation:

Rectangle- Rectangles always have congruent sides and right angles

Rhombus- A rhombus is a parallelogram which makes it congruent but it does not have a right angle

Square- A square has both congruent sides and right angles every time as it is equal and straight on every side

Answer:

4 congruent sides- rhombus

4 right angles- rectangle

4 congruent and 4 rights - square

Answer:

119.0 cm²

Step-by-step explanation:

What is surface area

It is the area of the outside part of anything. Surface area is also called total surface area.

As we can see from the pyramid, it has a square base. How do I know that it is a square base, is by seeing the dimensions of the base, which are 6.4 cm by 6.4 cm in this pyramid. And we already know from basic Geometry that a square has 4 equal sides. So we call it a square pyramid.

So to find the total surface area of this square pyramid, we need the area of the 4 triangular faces and the area of the square base.

So t.s.a of the pyramid = 4 × Area of each triangular face + Area of the square base.

So, total surface area = Area of square base + Area of the four triangular faces.

     total surface area = (length²) + (4 × [tex]\frac{1}{2}[/tex] × base × height)

     total surface area = (6.4 × 6.4) + (4 × [tex]\frac{1}{2}[/tex] × 6.4 × 6.1)

     total surface area = 40.96 + 78.08

     total surface area = 119.04 cm² ≈ 119.0 cm² (to the nearest tenth) (Answer)

[tex]2( \frac{1}{2} \times 15 \times 16) + 2(10 \times 17)[/tex]

Answer:

Step-by-step explanation:

[tex]\angle 1\:and \: \angle 2[/tex] Add to 180°

[tex]\angle 1\:and \: \angle 3[/tex] Equal

[tex]\angle 3\:and \: \angle 4[/tex] Add to 180°

[tex]\angle 2\:and \: \angle 4[/tex] Equal

Answer:

4

Step-by-step explanation:

I think its 4 because first, the 2 top tringles make a square, and 1+1=2. Then the 2 bottom ones make 2 more squares because one big triangle is equal to 1 square unit. So, its four.

2 & 3 - although 4 is also correct.

Answer:

B

Step-by-step explanation:

this is because she is only making less than or equal to 16 hotdogs, which the sigh indicates in answer B

Answer:

B

Step-by-step explanation:

It will be letter B because when it says at most it would be equal to 16 or less than 16 so, therefore, it will be letter B. The answer will not be for the burgers because since it says she plans to cook 30 burgers and not at most or at least it would mean that the answer will be either A or B.

I'm sorry, my explanation doesn't really make sense but I hope you kind of understood it.

Have a good day!

Answer

Only 3 cases: 1 2 or 3

prob ( less than 4 ) = 3/36 = 1/12

Step-by-step explanation:

Answer:

The answer is 3/30 or 10%

Step-by-step explanation:

There are 6 numbers: 1, 2, 3, 4, 5, and 6. You can only roll less than 4 3 out of 30 times, so it's 3/30 or 10%.

how many brownies are there

Answer/Step-by-step explanation:

From the first attachment or we can also say:

https://brainly.com/question/27391854

Base on first attachment:

There are 12 people ⇒ Emily, Delvenal, 10 other friends that was suppose to come

Either :

cut the pan of brownies into the 12 pieces

cut the pan of brownies into 24 pieces

But from this second attachment we know that:

Out of the 10 friend that war suppose to come only 7 came.

Thus if they cut the pan of brownies into 12 pieces then

Emily and delvenal + 7 friend = 10 people

12 - 10 = 2

Hence, 2 pieces of brownies are left.

Thus, if they cut the pan of brownies into 24 pieces then

Emily and delvenal + 7 friend = 10 people

24 - 10 = 14

Hence, 14 pieces of brownies are left.

Answer:

6 (the last one)

Step-by-step explanation:

In order to isolate f you need to divide by 5/6

So, then you need to divide both sides by 5/6.

f=5(6/5) remember dividing is the same as multiplying by the reciprical.

f=6

Answer:

The answer is F = 6

Step-by-step explanation:

Solve for f

by simplifying both sides of the equation, then isolating the variable.

Answer:

Option A is right

Step-by-step explanation:

In any data set, we find that the range is the difference between maximum and minimum.  The range cannot give full information about the variability of the data set.

Outliers are the ones which are either below Q1-1.5IQR or Q3+1.5IQR

Thus Inter quartile range, the difference between I quartile and III quartile gives a better idea about variability and also outlier.

Hence out of the four options given, we find that option B is the right one.

Option

A. The IQR is the best measure of variability because the distribution has an outlier.

Answer: the answer is a

Step-by-step explanation:

equation: 11 x 15= ?

since your dividing by 1 sq. ft. The answer stays the same.

15x11=165

Step-by-step explanation:

This is how we can find mean

Take each number in the data set, subtract the mean, and take the absolute value. Then take the sum of the absolute values. Now compute the mean absolute deviation by dividing the sum above by the total number of values in the data set.

Now finding mean by this process

   4        *       9/4     *     23/4   = 51.75 in^3

Answer:

  not a right triangle

Step-by-step explanation:

The side lengths do not meet the requirements of the Triangle Inequality. The given figure is not even a triangle.

_____

Additional comment

The triangle inequality requires the sum of the two short sides exceed the long side:

  3 + 9 > 12 . . . . not true

__

The converse of the Pythagorean theorem tells you that the triangle is a right triangle if the sum of the squares of the short sides is equal to the square of the long side: 3² +9² = 12² (not true). Here, that criterion is not met, so the triangle is not a right triangle.
