Volume = length x width x height.

Dimensions:

Length = 3 1/2 ft = 7/2 ft

Width = 5 ft

Height = 2 1/2 ft = 5/2 ft

Substitute and Find Volume:

Volume = (7/2 ft) x (5 ft) x (5/2) ft

The addition of the given fractions ( 1/6 + 2/4 ) to its simplest fraction form is 2/3.

Given that;

1/6 + 2/4

First, multiply the denominators then cross-multiply nominators and denominators.

1/6 + 2/4 = ( (6×2) + ( 4×1 ) ) / 6 × 4

1/6 + 2/4 = ( 12 + 4 ) / 24

1/6 + 2/4 = 16 / 24

We simplify

1/6 + 2/4 = 16 / 24 = 2/3

Therefore the addition of the given fractions ( 1/6 + 2/4 ) to its simplest fraction form is 2/3.

Answer:

  A. one solution; lines intersect at one point

  B. (x, y) = (3, 4)

Step-by-step explanation:

A linear equation will be represented on a graph by a straight line. A pair of equations will graph as a pair of lines. If the lines are not coincident or parallel, they will intersect at exactly one point. That point is the solution to the pair of equations.

__

A graph of the given points quickly shows the lines are not parallel or coincident. Each point on line A satisfies the equation that describes the line. Each point on line B satisfies the equation that describes line B. The point of intersection is a point that satisfies both equations.

A pair of distinct non-parallel lines can have at most one point of intersection. Hence there can only be one solution to the pair of equations.

Answer:

maybe the answer is x-y =-5

Answer:

Yes, they are congruent. They must be congruent because you know that 3 out of the 3 angles are identical between the two triangles. You know this because both triangles have a right angle (90°) and another identical angle (the two curves). This means that the 3rd angle for both triangles must be identical as well. Therefore, the triangles are the same.

Transformation involves changing the form of a function. The function that represents is C; [tex]g(x) =- \sqrt[3]{x+1}[/tex]

The function is a type of relation, or rule, that maps one input to specific single output.

Function f(x) is given byy;

[tex]g(x) = \sqrt[3]{x}[/tex]

f(x) is reflected across the x-axis.

The rule of this transformation (i.e. reflection) is:

(x, y) ⇒ (x, - y)

So,

[tex]f'(x) = -f(x)[/tex]

This gives

[tex]f'(x) = - \sqrt[3]{x}[/tex]

Now, f'(x) is translated 1 unit left

The rule of this transformation (i.e. translation) is:

(x, y) ⇒ (x+ 1, y)

So,

g(x) = f'(x+ 1)

This gives

[tex]g(x) = -\sqrt[3]{x+1}[/tex]

Hence, the function that represents g(x) is (c)

Answer:

42 ounces

Step-by-step explanation:

18 x 16 = 288

288 + 6 = 294

294/7 = 42

1-pound equals 16 ounces, since there are 18 pounds you will multiply 18 pounds by 16, then you will get 288, add your 6 ounces from the question, you will get 294, lastly divide by 7, which you will end up with 42

The measure of the angle Y from the given diagram is 102.5 degrees

In order to determine the unknown angle, we will use the theorem "angle at the vertex is half the angle at its intercepted arc".

Given the following

angle at the arc= 205 degrees

required

angle at the vertex Y

According to the theorem;

<Y = 1/2arcXZ
<Y = 1/2(205)
<Y = 102.5 degrees

Hence the measure of the angle Y from the given diagram is 102.5 degrees

Step-by-step explanation:

the picture is not representing the real angle sizes. so, don't let yourself get confused by that.

the right neighbor angle of 90° at E is also 90°.

it has to be, because it is the supplementary angle to the left 90° (that means together they are 180°).

remember, all angles around a single point on one side of a line have to sum up to 180° (because the line can be seen as the diameter of a circle, with the point being the center of the circle, and so one side of the line is representing a half-circle and therefore 180°).

for the same reason angle 1 (the lower neighbor of the 90° angle at A) is also 90°.

for the same reason the lower neighbor angle of the 60° angle at E is 180 - 60 = 120°.

for the same reason the angle ABC is 180 - 40 = 140°.

for the angle BCD we need to remember :

the sum of interior angles of a polygon with n sides is

(n − 2) × 180°.

in our case ABCDE has 5 sides, so the sum of all interior angles is

(5 - 2) × 180 = 3×180 = 540°

we know 4 of the interior angles already, so

angle BCD = 540 - 90 - 90 - 120 - 140 = 100°

x is now the supplementary angle to the angle BCD.

so,

x = 180 - 100 = 80°

The option second "A number line from negative 5 to 5 in increments of 1. An open circle is at 3 and a bold line starts at 3 and is pointing to the right" is correct.

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.

The options are attached in a picture please refer to the attached picture.

We have an inequality:

3(8 – 4x) < 6(x – 5)

After solving:

8 - 4x < 2(x - 5)

8 - 4x < 2x - 10

8 + 10 < 2x + 4x

18 < 6x

3 < x  or

Answer:  B. They are one-dimensional objects

This applies to line segments and lines as well.

One dimensional objects are such that they only have one component to them when it comes to determining a location on that object.

For instance, a number line is one dimensional because we only need one number to determine where a location is.

A ray is effectively a half-line, or put another way, a line is the combination of two rays glued together. Basically a ray points forever in one direction only, as a line will point in two opposite directions.
