Which of the following is not a layer of the Earth?

Answer:

Answer is choice C. We distribute the outer 2 into each of the inner terms (x and -4). Choice D is a trick answer because a lot of the time you might forget to multiply the 2 by the -4 inside the parenthesis (common mistake).

2 times x = 2x

2 times -4 = -8

2 times (x-4) = 2x-8

Side Note: Another path to solve this equation is to divide both sides by 2, then to add 4 to both sides.

Answer:

[tex] \frac{HI}{Jk} [/tex]

Step-by-step explanation:

Recall that, when two triangles are said to be similar to each other, it means that their corresponding side lengths are proportional and the ratio of their side lengths are equal.

We are given that ∆HLI ~ ∆JLK which is justified by the SSS similarity theorem, therefore, [tex] \frac{HL}{JL} = \frac{IL}{KL} [/tex]. This ratio will also be equal to the ratio of the corresponding lengths of their third side, that is:

[tex] \frac{HI}{Jk} [/tex]

(See attachment where both ∆s have been drawn for better understanding).

Step-by-step explanation:

it goes from the top of the graph to the bottom in the same position

so u just need to reverse the negatives and positives

Line p must be drawn so that it can lie in the same plane as line 1

Line p must be drawn in a way that allows it to lie in the same plane as line l.

In geometry, a plane extends in two dimensions indefinitely. There is no width. In coordinate geometry, a plane can be seen as an example. The positions of points in a plane are determined by their coordinates.

A plane is a flat, two-dimensional surface in mathematics that extends indefinitely. A plane is a two-dimensional analog that can incorporate three dimensions of space, a line, and a point.

Given two planes A and B,

and line l is in plane A,

to draw a line parallel to l,

"Two lines in the same plane, which are equally spaced apart and never cross" are parallel lines.

In order for a new line, p, to lie in the same plane as line l, it must be drawn parallel to line l.

Plane A contains line l.

Thus, plane A is where the line p must be drawn.

Hence option C is correct.

Answer:

The correct expression = 4 / 1/5

The number of rows = 20 rows

Step-by-step explanation:

1/5 Packets of C = 1 row

4 packets of C = x

Cross Multiply

1/5 × x = 4 × 1

The correct expression is

x = 4/ 1/5

x = 4 ÷ 1/5

x = 4 × 5

x = 20 rows

The number of rows Ryan can plant is 20 rows.

Answer:  B.) y-1 = x-1

Step-by-step explanation:

The normal format for point-slope equations is

(y - b) = m(x - a)   a is the x-value of the given coordinate, b is the y-value and m is the slope

Here, the slope is 1, so it is understood, and 1 always "disappears" when it is a factor

So substituting the values given

(y - 4) = (x - 1)  The parentheses are unnecessary because there is no "m"

Step-by-step explanation:

A box holds a white button, a brown button and a black button.

Hence:

Number of white button= 1

Number of brown button= 1

Number of black button= 1

Total number of buttons = 3

The probability of picking a white button then without replacing it, picking a brown button on the second pick is :

= P(White) × P(Brown) [ without replacement]

= 1/3 × 1/2

= 1/5

In decimal = 0.2

0

Answer:

here ya go, got the answer after I submitted

Explanation:

The lowest point occurs when y = 0.

The highest point occurs when y = 12.

The range is therefore [tex]0 \le y \le 12[/tex] which converts to [tex][0,12][/tex] which is interval notation. The square brackets tell us to include the endpoints. So we're saying that y can be anything between 0 and 12, including both endpoints.

The range is the set of all possible y outputs of a function.

The lengths of the sides of the rectangle are 13 inches and 15 inches

Step-by-step explanation:

The perimeter of a rectangle

Given the two sides of a rectangle a and b. The perimeter of the rectangle is:

[tex]P=2(a+b)[/tex]

We are given the perimeter of a rectangle as:

[tex]P=8(2x+1)[/tex]

And each side has a length of 3x+4 and 4x+3. Calculating the perimeter:

[tex]P=2(3x+4+4x+3)=2(7x+7)[/tex]

We set up the equation:

[tex]8(2x+1)=2(7x+7)[/tex]

Dividing by 2:

[tex]4(2x+1)=7x+7[/tex]

Operating:

[tex]8x+4=7x+7[/tex]

Subtracting 7x:

[tex]x+4=7[/tex]

Subtracting 4:

x=3

The length of each side is:

3x+4=3*3+4=13

4x+3=4*3+3=15

The lengths of the sides of the rectangle are 13 inches and 15 inches

Answer:

[tex]\sqrt{33}[/tex]

Step-by-step explanation:

Use the Pythagorean Theorem For the Triangle with Sides 11, 13, and Height(blue dashed line)

b=height (blue-dashed line)

[tex]11^2+b^2=13^2[/tex]

[tex]169-121=b^2[/tex]

[tex]48=b^2[/tex]

[tex]\sqrt{48} =b[/tex]

Use the Pythagorean Theorem Again for sides 9, x, and height which is [tex]\sqrt{48}[/tex]

[tex]x^2+\sqrt{48}^2=9^2[/tex]

([tex]\sqrt{48}^{2}[/tex] is [tex]48[/tex]

[tex]81-48=x^2[/tex]

[tex]33=x^2[/tex]

[tex]x=\sqrt{33}[/tex]

[tex]\huge\boxed{\text{0.17 hours}}[/tex]

Step-by-step explanation:

We can create two ratios to find how long you can use a bike for one dollar.

Let's set up a ratio in the form [tex]\frac{cost}{hours}[/tex]

We know it costs $23 to ride for 4 hours, so we can make the fraction [tex]\frac{23}{4}[/tex].

We also know that for $1, we'll have some unknown time for the bike. We can represent this as [tex]\frac{1}{x}[/tex].

Since the constant of proportionality has to be the same, we can set these two ratios equal to each other.

[tex]\frac{23}{4}=\frac{1}{x}[/tex]

We can now solve for x by cross multiplying.

[tex]1 \cdot 4 = 4\\\\4 \div 32 \approx 0.17[/tex]

So $1 will get you around 0.17 hours of bike time.
