Answer:x=$7.31

Step-by-step explanation:6lbs

6lbs x/6lbs=43.86$lbs/6lbs

The total surface area of the solid object is the sum of the surface area of the cylinder and the surface area of the cone.

The surface area of the cylinder is 2πr(r+h), where r is the radius of the cylinder and h is its height.

The surface area of the cone is πr(l+r), where r is the radius of the cone and l is its slant height.

Since the cylinder and the cone have the same radius, we can call this radius r.

The total surface area of the solid object is therefore 2πr(r+h) + πr(l+r).

We are told that this total surface area is equal to 6336/210 = 30 sq. cm.

Thus, we can set up the equation: 2πr(r+h) + πr(l+r) = 30.

We are trying to find the value of l, which is the slant height of the cone. We are given the value of h, which is the height of the cylinder. We can substitute this value into the equation to get:

2πr(r+30) + πr(l+r) = 30.

This equation can be rearranged and solved for l to find the slant height of the cone.

l = sqrt(900 - 60r).

Since we are given that the slant height of the cone is 26 cm, we can substitute this value into the equation to solve for the radius of the cone:

26 = sqrt(900 - 60r)

Solving for r, we find that the radius of the cone is 15 cm.

Substituting this value back into the equation for the slant height of the cone, we find that the height of the cone is:

l = sqrt(900 - 60(15)) = sqrt(300) = 17.67 cm.

Thus, the height of the cone is approximately 17.67 cm.

By using slope intercept form of equation of line, the graph of

h(x) = [tex]-\frac{2}{5}x + 4[/tex] has been shown

What is equation of line in slope intercept form?

The most general form of equation of line in slope intercept form is given by y = mx + c

Where m is the slope of the line and c is the y intercept of the line.

Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.

If  [tex]\theta[/tex]  is the angle that the line makes with the positive direction of x axis, then slope (m) is given by

m = [tex]tan\theta[/tex]

The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.

The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.

Let the independent variable be x and dependent variable be h(x)

The dependent variable decreases 2 units for every 5 units the independent variable increase.

Slope = [tex]-\frac{2}{5}[/tex]

So,

h(x) = [tex]-\frac{2}{5}x + c[/tex]

Now,

h(0) = 4

So, c = 4

h(x) = [tex]-\frac{2}{5}x + 4[/tex]

The plane is perpendicular to the axis but does not go through the vertex. The plane intersects the double cone at only the vertex is ellipse.

A planar curve that has two focal points is normally called an ellipse on the condition that at every point on the curve, it will be seen that the sum of the two distances from the focal points is constant. This generalizes the shape of a circle, which is a unique variety of an ellipse whereby the two focus points coincide.

The plane is said to not be intersecting with the vertex, not parallel to the axis nor perpendicular to the axis, then not parallel to the side of the cone, but it intersects only one cone is called a circle.

A circle is defined as a closed, two-dimensional object whereby every point in the plane is seen to be equally spaced from a central point. The line of reflection symmetry is seen to be formed by all lines that transverse the circle. Additionally, every angle has rotational symmetry around the center.

Thus, the conclusion is that the first two options are properties of an ellipse.

The area of the paper that remains is 375.04cm².

What is an area?

The measurement that expresses the size of a region on a plane or curved surface is called an area. Surface area refers to the area of an open surface or the boundary of a three-dimensional object, whereas the area of a plane region or plane area refers to the area of a form or planar lamina.

Here,

We take it that the semicircles cover the full width of the paper.

So the radius is 16/2 = 8 cm

Since there are two of them, the area is full circle.

First, we find the area of the rectangle before the cuts were made.

Area = L * W

L = 36

W = 16

Area = 36×16 = 576 cm²

Now, we find the area of the circle cutouts.

r = 8

Area = pi * r²

Area = 3.14 * 8²

Area = 3.14 * 64

Area = 200.96cm²

Now, we find the total area left

Total Area Left = rectangle - circle

Total Area Left = 576 - 200.96

Total Area left = 375.04cm².

Hence,  the area of the paper that remains is 375.04cm².

The equivalent form of the compound inequality is -9>-x≥-10.

A sentence having two inequality statements connected by the words "or" or "and" is referred to as a compound inequality. The conjunction "and" denotes the simultaneous truth of both statements in the compound sentence. It is when the solution sets for the various statements cross over or intersect. The conjunction "or" means that the entire compound sentence is true as long as either of the two statements is true. It consists of the union or combination of the solution sets for the various statements. A conjunction is a compound inequality that contains the word "and." Even though "and" and "or" are considered to be conjunctions of speech, their meanings in mathematics are distinct from their grammatical counterparts. The conjunction (part of speech) "or"—when used to demonstrate this point—is whenever used in a compound inequality, it creates a disjunction, as the name suggests. Simply keep in mind that "con" stands for "with another" and "dis" for "one OR the other."

Total number of tables in dining hall = 20 people

The number of people who can seat at long table = 10 people

The number of people who can seat at the round table = 10 people

According to the question, let’s assume a linear equation in two variables

number of long tables = x

number of round tables = y

⇒ x +y=20 ………… (1)

⇒10 x + 8 y=182 ………...(2)

Multiply equation (1) by 8 and subtract it from equation 2.

⇒ 10x+8y=182 ………… (2)

⇒ 8x+8 y=160 ………....(1)

⇒2x=22

⇒x=11

now put the value of x in equation (1) we get,

The distance traveled by train would be 300 miles.

What is the relation between speed, distance, and time?

You can use the equivalent formula d = rt which means distance equals rate times time. To solve for speed or rate use the formula for speed, s = d/t which means speed equals distance divided by time. To solve for time use the formula for time, t = d/s which means time equals distance divided by speed.

A train travels for 3.75 hours at 80 miles per hour.

The distance traveled = speed * time

                                     = 3.75 * 80
