What is a cylinder?

One of the most fundamental curvilinear geometric shapes, a cylinder has traditionally been a three-dimensional solid. It is regarded as a prism with a circle as its base in basic geometry. In many contemporary branches of geometry and topology, a cylinder can also be defined as an infinitely curvilinear surface.

Given that the height of a cylinder is 3.5 feet. The diameter of the cylinder is 2 feet.

The radius of the cylinder is half of the diameter.

The radius of the cylinder is 2/2 = 1 foot.

The volume of a cylinder is πr²h.

r = radius, h = height

The volume of the cylinder is

π×1²×3.5

= 3.14 × 3.5

= 10.99 cubic foot

= 10.99 × 7.48 gallons

= 82.205 gallons

= 82.21 gallons

Using the concept of rates, the machine will complete 9 9/64 inches in 8.67 minutes

To determine how long it will take to turn a particular length of iron, we can calculate the rate at which it works and it must be in a definite proportion.

If the lathe moves 3/128 in one revolution.

And the machine completes 45 revolutions in 1 minutes, we can determine how many inches in moves in that minute.

3/128 in = 1 rev

x in = 45

45 * (3/128) = 45 revolutions = 1 minute

1.054 inches in 1 minute.

We can further use this to determine the time it takes to move 9 9/64 inches

1.054 inches = 1 minute

9 9/64 inches = x minute

cross multiply both sides and solve

x = 8.67 minutes

The coordinates of the endpoints of rs are r(1,11) and s(6,1). point t is on rs and divides it such that rt:st is 4:1.

the coordinates of the point t are (5, 3)

We may utilise the notion of section formula to get the coordinates of point T, which states that if we have two points A(x1, y1) and B(x2, y2) and a point P splitting the line segment AB in the ratio m:n, then the coordinates of point P can be calculated using the following formula:

P = ((mx2 + nx1)/(m+n), (my2 + ny1)/(m+n))

In this situation, we have the coordinates of points R and S, as well as the ratio of T divided by RS. So, let's enter the following values into the formula to determine T's coordinates:

Let the coordinates of point T be (x, y), and the ratio of T to RS be 4:1, implying that RT:ST = 4:1. This means that RT = 4/5 (RS length) and ST = 1/5. (length of RS).

RS length =[tex]sqrt((6-1)^2 + (1-11)^2)[/tex] = [tex]sqrt (146)[/tex]

RT=[tex](4/5) * sqrt(146)[/tex] = [tex](4/5) * 12.083[/tex] = 9.666

ST =[tex]1/5* sqrt(146)[/tex] = [tex]1/5* 12.083[/tex] = 2.4166

We get the following using the section formula:

x = (4×6 + 1×1)/(4+1) = 5

y = (4×1 + 1×11)/(4+1) = 3

T = (5, 3)

The probability that a student choosen at random likes english but not maths is 299/676.

Let A be the event that a student likes math, and B be the event that a student likes English.

From the given information, we know that:

P(A) = 15/26

P(B) = 13/26

P(neither A nor B) = 9/26

To find the probability that a student chosen at random likes English but not math, we can use the formula:

P(B and not A) = P(B) - P(A and B)

The probability of A and B can be found by multiplying the probabilities of A and B together, since they are not independent:

P(A and B) = P(A) × P(B) = (15/26) × (13/26) = 195/676

Substituting the given probabilities into the formula, we get:

P(B and not A) = (13/26) - (195/676)

Simplifying, we get:

P(B and not A) = 299/676

The probability of selecting a person who is either a Democrat or a woman is 0.8, or 80%.

Probability is a branch of mathematics that deals with the study of random events. It is used to predict the likelihood of an event occurring.

Let's start by finding the probability of selecting a Democrat. We are given that there are 60 Democrats in the group of 100 people. Therefore, the probability of selecting a Democrat at random is:

P(Democrat) = 60/100 = 0.6

Next, let's find the probability of selecting a woman. We are given that there are 60 women in the group of 100 people. Therefore, the probability of selecting a woman at random is:

P(Woman) = 60/100 = 0.6

Now, we need to find the probability of selecting both a Democrat and a woman. We are given that 40 of the Democrats are women. Therefore, the probability of selecting a woman who is also a Democrat is:

P(Democrat and Woman) = 40/100 = 0.4

To find the probability of selecting a person who is either a Democrat or a woman, we add the probabilities of selecting a Democrat and selecting a woman, and then subtract the probability of selecting both a Democrat and a woman. Therefore, the probability of selecting a person who is either a Democrat or a woman is:

P(Democrat or Woman) = P(Democrat) + P(Woman) - P(Democrat and Woman)

Answer:

m angleJ= 53, m angle JML = 63.5

Step-by-step explanation:

As this is a circle, KJ and KL are radii, which are equal

If we join J and L to form JL, Triangle KJL becomes and isosceles triangle( two sides equal).

That means, the angles J and L are equal (isosceles triangle thm).

Therefore- m angleJ = 180 - 127

m angleJ = 53

Join J and K, and L and K

Another circle theorem- The angle subtended by an arc/chord on the centre is double the angle subtended by the chord on any other point on the circle.

Therefore- angle JML  = (1/2)127
So, m angleJML = 63.5

The expression equivalent to (-√8 -√2) + √-36 is -3√2 + 6i.

A real number and an imaginary number are effectively combined to create a complex number. The complex number is written as a+ib, where a and ib are real and imaginary numbers, respectively. Additionally, I = -1 and both a and b are real numbers.

Consequently, a complex number is a straightforward illustration of the addition of two integers, specifically a real number and an imaginary number. It consists of two parts: one that is entirely real, the other entirely fantastical.

The given expression is:

(-√8 -√2) + √-36

The expression can be written as:

(-2√2 - √2) + √(i)²(6)²

Taking the common term:

√2(-2 - 1) + 6i

Answer: BD = 60.34

Step-by-step explanation:

8x -33 = 2x+37

Take away 2x from both sides ( the 2x will cancel out)

Add the 33 to both sides. (The -33 will cancel out)

Now you are left with 6x = 70

Divide both sides by 6.

x = 11.67 (rounded by the hundredth) (11.66666...)

Now to figure out BD your new equation is 2(11.67) + 37

After multiplying you get 23.34 + 37.

No, you cannot stop at the step 3x = 126 degrees. The measure of angle JML is approximately 56.67 degrees

What is the measure of angle θ?

A radian is the length of an arc formed by an angle that, when shown as a central angle, equals the length of the circle's radius.

No, you cannot stop at the step 3x = 126 degrees.

To find the measure of angle JML, we need to solve for x and then use that value to find the measure of the angle.

We can start by using the fact that the angles in triangle JLM must add up to 180 degrees. We have:

m∠JLM + m∠JML + m∠LMJ = 180

Substituting the given values, we get:

4x + (2x + 18) + (3x - 12) = 180

Simplifying and combining like terms, we get:

9x + 6 = 180

Subtracting 6 from both sides, we get:

9x = 174

Dividing both sides by 9, we get:

x = 19.33...

Now that we have the value of x, we can use it to find the measure of angle JML. We have:

m∠JML = 2x + 18

Substituting x = 19.33..., we get:

m∠JML = 2(19.33...) + 18 = 56.67...

Therefore, the measure of ∠JML is approximately 56.67 degrees
