The density of silver (Ag) is 10.5 g/cm3. Find the mass of Ag that occupies 965 cm3 of space.

Answer:

Both Anoki and David are correct. Both expressions are equivalent to the difference between the measurements and are always positive because they give the absolute value of the difference.

Sorry for answering so late.

Step-by-step explanation:

Both of their absolute value expression is correct because the final height will always be same.

Given,

At a theme park, a person must be a certain height to ride a rollercoaster.

A person must be h inches tall, plus or minus 1.5 inches.

Anoki says the absolute value expression | 1.5 - h | represents an acceptable height.

David says the absolute value expression I h - 1.5 | represents an acceptable height.

We have to find who is correct in expressing the absolute value.

It is expressed in | x |.

Where x is any number.

The value of x can be negative or positive.

The absolute value will always be a positive value.

|m| =  and |-m| = m.

We have,

Anoki absolute value expression: | 1.5 - h |

David absolute value expression: | h - 1.5 |

Suppose let us consider h = 72.

Now,

| 1.5 - h | = | 1.5 - 72 | = | -70.5 | = 70.5

| h - 1.5 | = | 72 - 1.5 | = | 70.5 | = 70.5

We see that both have the same value.

Thus both of their absolute value expression is correct.

Answer:

[tex]\boxed {x = 7}[/tex]

Step-by-step explanation:

[tex]FJ[/tex] and [tex]JH[/tex] is half of the whole measurement of [tex]FH[/tex]. So, to find the value of  [tex]x[/tex], you need to write an expression by using those measurements of both [tex]FJ[/tex] and [tex]JH[/tex]. Then, solve for [tex]x[/tex]:

[tex]FJ = 24[/tex]

[tex]JH = 3x - 3[/tex]

[tex]3x - 3 = 24[/tex]

-Solve:

[tex]3x - 3 = 24[/tex]

[tex]3x - 3 + 3 = 24 + 3[/tex]

[tex]3x = 27[/tex]

[tex]\frac{3x}{3} = \frac{27}{3}[/tex]

[tex]\boxed {x = 7}[/tex]

So, the value of [tex]x[/tex] is [tex]7[/tex].

If this figure was a parallelogram, then the opposite angles would be congruent. This would make angles B and D the same measure

angle B = angle D

x^2+20 = 7x+50

x^2+20-7x-50 = 0 .... get everything to one side

x^2-7x-30 = 0

(x-10)(x+3) = 0 ... see note below

x-10 = 0 or x+3 = 0

x = 10 or x = -3

Note: In this step is where the factoring occurs. To factor, we need to find two numbers that multiply to -30 which is the last term, and also add to -7 which is the middle coefficient. This is a trial and error process. You should find that -10 and 3 both multiply to -30 and add to -7. I suggest making a table as shown below (attached image) to list out all the possible choices.

Perhaps a much more efficient route is to use the quadratic formula.

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

We found two possible solutions for x. If x = 10, then 7x+50 is 7(10)+50 = 120 which is an obtuse angle. If x = -3, then 7x+50 = 7(-3)+50 = 29 which is acute.

Assuming the diagram is drawn to scale, this means angle D is obtuse and we'll go with x = 10 and 7x+50 = 120

Angles A and D add to 180 degrees. This is true for any pair of adjacent angles in a parallelogram.

A+D = 180

A+120 = 180

A = 180-120

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

This answer is based on the assumption that the diagram is drawn to scale and that this quadrilateral is a parallelogram.

Answer:

[tex]\angle A=60\textdegree[/tex]

Step-by-step explanation:

So we have the following parallelogram and we wish to solve for ∠A.

To do so, we will need to solve for x first. Look carefully at the parallelogram...

Notice that ∠A and ∠D are consecutive angles. In other words:

[tex]\angle A+\angle D=180[/tex]

Since we have an equation for ∠D, substitute:

[tex]\angle A+7x+50=180[/tex]

Notice that ∠A and ∠B are also consecutive angles. So:

[tex]\angle A+\angle B=180[/tex]

We know the equation for ∠B. Substitute:

[tex]\angle A+x^2+20=180[/tex]

Since both equations equal 180, we can set them equal to each other:

[tex]\angle A+7x+50=x^2+20+\angle A[/tex]

Let's subtract ∠A from both sides. This gives us:

[tex]7x+50=x^2+20[/tex]

Now, we can solve for x. This is a quadratic, so let's move all the terms to one side. To start off, let's subtract 50 from both sides:

[tex]7x=x^2-30[/tex]

Now, let's subtract 7x from both sides:

[tex]0=x^2-7x-30[/tex]

Solve for x. We can factor.

Here's the trick to factoring. If we have the following:

[tex]0=ax^2+bx+c[/tex]

The we will need to find two numbers, p and q, such that:

[tex]p+q=b\text{ and } pq=ac[/tex]

In our equation, a is 1, b is -7, and c is -30.

So, we want two numbers that sum to -7 and multiply to (1)(-30)=-30.

We can use -10 and 3. -10+3 is -7 and -10(3) is -30. So, let's substitute our b term for -10x and 3x. In other words, we have:

[tex]0=x^2-7x-30[/tex]

Substitute -7x for 3x-10x. This gives us:

[tex]0=x^2+3x-10x-30[/tex]

This is equivalent to our old equation.

Now, we can factor. Factor out a x from the first two terms:

[tex]0=x(x+3)-10x-30[/tex]

And factor out a -10 from the two last terms:

[tex]0=x(x+3)-10(x+3)[/tex]

Since the expressions within the parentheses are the same, we can use grouping to acquire:

[tex]0=(x-10)(x+3)[/tex]

Note that this is essentially the distribute property. If we distribute, we will get the same as above.

Zero Product Property:

[tex]x-10=0\text{ or }x+3=0[/tex]

Solve for x:

[tex]x=10\text{ or } x=-3[/tex]

So, we have two cases for x. Each case will yield a different answer for ∠A.

Case I: x=10

Use our original equation of:

[tex]\angle A+7x+50=180[/tex]

Substitue 10 for x:

[tex]\angle A+7(10)+50=180[/tex]

Multiply:

[tex]\angle A+70+50=180[/tex]

Add:

[tex]\angle A+120=180[/tex]

Subtract 120 from both sides:

[tex]\angle A=60\textdegree[/tex]

So, in our first case, ∠A is 60°

Case II: x=-3

Again, same equation:

[tex]\angle A+7x+50=180[/tex]

This time, substitute -3 for x. This yields:

[tex]\angle A+7(-3)+50=180[/tex]

Multiply:

[tex]\angle A-21+50=180[/tex]

Add:

[tex]\angle A+29=180[/tex]

Subtract 29 from both sides:

[tex]\angle A=151\textdegree[/tex]

So, in our second case, ∠A is 151°

However, 151° doesn't seem likely with how the figure is drawn.

Therefore, our final answer is 60°.

And we're done!

The best subset that describes the dimension of a rectangle is the set of all rational numbers.

We have,

The dimension of a rectangle refers to its length and width, which are usually measured in units such as feet or meters.

These measurements can be any real number, including irrational numbers such as √2 or π.

Now,

The only subset of the rational numbers listed in the answer choices is the positive rational numbers, which are the set of all numbers that can be expressed as a ratio of two integers where the denominator is not zero and the numerator and denominator are both positive.

While the dimensions of a rectangle can be positive rational numbers, they can also be negative rational numbers or zero, as long as they satisfy the properties of a rectangle (e.g., length and width are both positive, and the angles are right angles).

Therefore, the answer is not D.

Also, whole numbers and integers are not sufficiently precise to describe the dimensions of a rectangle, as they do not include fractions or decimals.

The only subset of rational numbers that include all possible values for the dimensions of a rectangle is the set of all rational numbers, which includes positive, negative, and zero rational numbers, as well as fractions and decimals.

Therefore,

The best answer is "the set of all rational numbers".

2. M=3

3.X=5

Step-by-step explanation:

1. The length is just how many units between each point

2. Find the average of the two points (use absolute value)

(|-4|+10)÷2=(4+10)÷2=14÷2=7, the midpoint is 7 units from each endpoint. so 10-7=3

3. the length of the line ac=10x, the parts are 12 and 8x-2 set up an equation

10x=12+8x-2 combine like terms

2x=10 divide both sides by 2

x=5

10+8x=10x

10= 10x-8x

10=2x
