What is the volume of this object? Enter answer as a mixed number.

u3

Answers

Answer:

31 1/4 units

Step-by-step explanation:

The equation for volume of a rectangular prism is length x width x height.

We know the length of the width and height are given as 2 1/2 u.

In this case we can simply find the height by counting the amount of blocks high it is, which in this case is 5.

Then we multiply the numbers together.

2 1/2 x 2 1/2 x 5 = 31 1/4

A polygonal shape is what?

A polygon is a two-dimensional, closed structure that is flat or planar and has straight sides. It lacks crinkled sides. The edges of a polygon are also referred to as its sides.

Describe polygons with an example.

Any two-dimensional form that can be made entirely of straight lines is referred to be a polygon. Polygons include forms like triangles, hexagons, pentagons, and quadrilaterals. The name of the shape has a side count indication.

Answer: 100%

Step-by-step explanation:

5. A number cube with the numbers 1-6
on its sides is rolled twice. What is the
probability of rolling ________
(a) a 1 and then a 6
(b) an even number and then an odd
number
(c) a number less than 3 and then a
number greater than 3

Write the probability as a reduced fraction

Answers

Answer:

Part - A = 1/36

Part - B = 1/4

Part - C = 1/6

Step-by-step explanation (Part - A):

The numbers on the cube are, 1 , 2 , 3 , 4 , 5 and 6.

Formula to calculate probability =
Total Number of the particular number / Total Number of Numbers

The probability of rolling 1 is 1/6 as there is only one 1 in a numbered cube.

The probability of rolling 6 is 1/6 as there is only one 6 in a numbered cube.

So, the probability of rolling 1 and 6 is 1/6 * 1/6.

The probability of rolling 1 and 6 = 1/36.

Step-by-step explanation (Part - B):

The numbers on the cube are, 1 , 2 , 3 , 4 , 5 and 6.

Formula to calculate probability =
Total Number of the particular number / Total Number of Numbers

The probability of rolling an even number is 3/6 = 1/2 because there are 3 even numbers in a numbered cube.

The probability of rolling an odd number is 3/6 = 1/2 because there are 3 odd numbers in a numbered cube.

So, the probability of rolling an even and an odd number is 3/6 * 3/6 = 1/2 * 1/2.

The probability of rolling an even and an odd number = 9/36 = 1/4.

Step-by-step explanation (Part - C):

The numbers on the cube are, 1 , 2 , 3 , 4 , 5 and 6.

Formula to calculate probability =
Total Number of the particular number / Total Number of Numbers

The probability of rolling a number that is less than 3 is 2/6 = 1/3 because there are 2 numbers that are less than 3 in a numbered cube.

The probability of rolling a number that is greater than 3 is 3/6 = 1/2 because there are 3 numbers that are greater than 3 in a numbered cube.

So, the probability of rolling a number that is less than 3 and a number that is greater than 3 is 2/6 * 3/6 = 1/3 * 1/2.

The probability of rolling a number that is less than 3 and a number that is greater than 3 is 6/36 = 1/6.

Part A

c = 66 per dress

Part B

$396

Okay, here are the step-by-step calculations:

Part A:

You were given the number 66. So we entered that as the cost (c) per dress in the equation.

Part B:

We were asked to find the cost of 6 dresses.

So we calculate:

Cost per dress (c) = $66

Number of dresses = 6

Total cost of 6 dresses =

$66 x 6 = $396

So the final answer for Part B is: $396

In summary:

We were given: Cost per dress (c) = $66

and asked for cost of 6 dresses

So we calculated: Cost per dress (c) = $66

Number of dresses = 6

Total cost = $66 x 6 = $396

Does this help explain the steps? Let me know if you have any other questions!

The names of the months of the year
were written on separate papers and
placed in a hat. Two papers are ran-
domly drawn one at a time, replacing
the first before the second draw. What
is the probability of drawing. ?
(a) April and then June
(b) a month ending in r and then a
month ending in y
(c) May and then not drawing May

Write the probability as a reduced fraction

Answers

Step-by-step explanation:

There are 12 months of the year, so there are 12 possible choices for each draw. Since the first paper is replaced before the second draw, each draw can be considered as independent and with replacement.

(a) To draw April and then June, we need to draw April on the first draw (with probability 1/12), and then June on the second draw (with probability 1/12). The probability of both events happening is the product of their probabilities:

P(April and then June) = (1/12) x (1/12) = 1/144

(b) To draw a month ending in r and then a month ending in y, we can choose from the following months: April, June, July, September, and November. There are 5 months that end in r, so the probability of drawing one of them on the first draw is 5/12. After replacing the first paper, there are still 12 months left in the hat, but now we want to draw a month ending in y. There are 4 months that end in y, so the probability of drawing one of them on the second draw is 4/12. Again, the probability of both events happening is the product of their probabilities:

P(month ending in r and then month ending in y) = (5/12) x (4/12) = 5/36

(c) To draw May on the first draw and not draw May on the second draw, the probability of drawing May on the first draw is 1/12, and the probability of not drawing May on the second draw is 11/12 (since there are 11 months left in the hat after May is drawn on the first draw). Again, the probability of both events happening is the product of their probabilities:

P(May and then not drawing May) = (1/12) x (11/12) = 11/144

Therefore, the probabilities are:

(a) 1/144

(b) 5/36

Step-by-step explanation:

P(April and then June) = (1/12) x (1/12) = 1/144

P(month ending in r and then month ending in y) = (5/12) x (4/12) = 5/36

P(May and then not drawing May) = (1/12) x (11/12) = 11/144

Therefore, the probabilities are:

(a) 1/144

(b) 5/36
