You Can Find The Volume Of A Cylinder By Using The Equation V=r2h. So, What Formula Can You Use To Find

Answers

Answer 1

Answer:

Ah, thats easy:

V=1/3hπr².

Step-by-step explanation:

Explanation, 3 cones can fit into a single cylinder, so the volume formula of a cone is the volume formula of a cylinder, divided by three (or multiplied by 1/3)

Hope this helps. :D

Answer:

D. Y = x + 2

Step-by-step explanation:

The slope increases at a rate of 1 / 1, which is written as just x. The line starts at 2, which is at the y-intercept, a.k.a, where you get the +2 from.

Answer:

y = 2 + x

Step-by-step explanation:

Line is passing through the points (0, 2) and (1, 3)

y-intercept (b) = 2

Slope of line (m) = (3 - 2)/(1 - 0) = 1/1 = 1

Equation of line in slope intercept form is given as:

y = mx + b

Plugging the values of m and b.

y = 1x + 2 = x + 2

y = 2 + x

Noah takes out a marble, records its color, and puts it back in. In 9 trials, he gets a green marble 3 times.
Estimate the probability of getting a green marble from this bag.
Answers: A. 15/25 B. 20/25 C. 9/25 D. 3/25

Answers

Answer:

6/B and 9/C 15/25

Step-by-step explanation:

The sample space for the outcomes are given by set theory where the probability is

a) S = 6 outcomes

b) P = 9 outcomes

c) A = 0.33

What is Probability?

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

Probability = number of desirable outcomes / total number of possible outcomes

The value of probability lies between 0 and 1

Given data ,

a)

Let the total number of outcomes be represented as S and P

where Lin selects one type of lettuce and one dressing to make a salad.

Lettuce types: iceberg, romaine

Dressings: ranch, Italian, French

So , S = 2 x 3 = 6 outcomes

b)

Diego chooses rock, paper, or scissors, and Jada chooses rock, paper, or scissors.

So , P = 3 x 3 = 9 outcomes

c)

Andre received a green marble in one out of every four attempts, making his percentage of green marbles 1/4, or 0.25.

Jada received a green marble in 5 out of the 12 trials, meaning that her percentage of green marbles was 5/12 0.417.

Noah received a green marble on 3 of the 9 tries, for a percentage of 3 out of 9 = 0.333.

We may average these ratios to obtain a general assessment of the likelihood of drawing a green marble from the bag:

(0.25 + 0.417 + 0.333) / 3 ≈ 0.333

Hence, the odds of pulling a green marble from the bag are around 0.333 (or 33.3%).

how many triangles can you make with two side lengths of 6 inches that meet at a 50 degree angle.

Answers

Answer: Exactly One Triangle

======================================================

Explanation:

Recall that by the SAS (side angle side) congruence theorem, if we know that two pairs of sides are the same length and the angles between them are also congruent, then we can conclude the triangles are congruent. This further means that we can only construct exactly one triangle with two side lengths of 6 inches, and they form a 50 degree angle between them. Applying transformations such as rotations, translations, or reflections will not change the triangle.

Side note: This triangle is isosceles because two sides are the same length. It is not equilateral because we would need to have all three angles to be 60 degrees.

Answer:

One triangle only

When rolling a number cube 500 times, how many times can you expect to roll an odd number?

Answers

Answer:

250 times

Step-by-step explanation:

Assuming this is a 6 sided cube, there is 3 odd number (1,3,5) so there is a 1/2 chance to roll an odd every time. If we roll the cube 500 times and expect it to land on an odd 1/2 the time, 1/2*500= 250.

We can expect to roll an odd number 250 times while rolling a number cube 500 times.

What are odd numbers?

A number which can not be divided by 2 is called the odd numbers.

What is Cube?

A cube is a three dimensional solid object bounded by six square faces or sides.

It is assumed that it is a 6 sided cube, so there must be 3 odd number (1,3,5) so there is a 1/2 chance to get an odd number every time. If we roll the cube 500 times and expect it to land on an odd 1/2 the time, 1/2*500= 250.

Therefore, when rolling a number cube 500 times, we can expect 250 times the odd numbers.

Answer:

  a.  1,128.8 m²

Step-by-step explanation:

The total surface area is the sum of the areas of the two identical triangular bases and the areas of the lateral rectangles.

The two bases together have an area of ...

  A = 2(1/2)(bh) = (10 m)(14 m) = 140 m²

__

The lateral area is the product of the prism height and the perimeter of the triangular base.

  LA = Ph = (10 m + 14 m + 17.2 m)(24 m) = (41.2·24) m² = 988.8 m²

Then the total area is ...

  base area + lateral area = 140 m² +988.8 m² = 1128.8 m²

The total surface area of the prism is 1128.8 m².

(y) equals the total salads made. In order to figure this out, you would have to add the 4 salads already made plus the 3 salads being made each hour for however many hours they are making them. Since we don’t know how many hours they are making them, we use (x).

Answer:

y(x) = 4 salads + (3 salads/hour)x

Step-by-step explanation:

We start with the initial value of this function, y(0), which is 4 salads.  To this quantity we add 3 salads per hour of work, using x to represent the number of hours.  In summary, we have:

y(x) = 4 salads + (3 salads/hour)x

Example:  after 2 hours the number of salads made is 4 salads plus (3 salads/hour)(2 hours). or y(2) = 4 salads + 6 salads = 10 salads.

We have come to dedicate a portion of that field as a final resting-place for those who here gave their lives that that nation might live. It is altogether fitting and proper that we should do this. But in a larger sense, we cannot dedicate, we cannot consecrate, we cannot hallow this ground. The brave men, living and dead who struggled here have consecrated it far above our poor power to add or detract. The world will little note nor long remember what we say here, but it can never forget what they did here. It is for us the living rather to be dedicated here to the unfinished work which they who fought here have thus far so nobly advanced. It is rather for us to be here dedicated to the great task remaining before us-that from these honored dead we take increased devotion to that cause for which they gave the last full measure of devotion-that we here highly resolve that these dead shall not have died in vain, that this nation under God shall have a new birth of freedom, and that government of the people, by the people, for the people shall not perish from the earth."Which of the following is the best summary of the line in bold?
