Also note that the formula for diameter is given as;

Diameter = 2 radius

Now, substitute the value of diameter

30 = 2r

Make 'r' the subject of formula

r = 15in

Substitute the values into the formula

Volume = 3. 14(15)²(42)

If you select four socks at random, the probability that at most three are blue is 42.9%.

Probability is the likelihood of an expected outcome occurring when many possible events can happen.

Probability is represented in percentages, fractions, and decimals to show that it describes what is likely from many outcomes.

The total number of socks in the drawer = 14

The number of blue socks = 8

The number of black socks = 6

The probability of getting a blue sock = 8/14

The probability of getting 3 out of 4 = 3/4

The combined probability = 8/14 x 3/4

= 42.86%

= 42.9%

Thus, when you randomly select four socks, you can probably get blue socks 42.9% of the time.

The number of posters Jill had on Monday are 18.

The equation is p + 8 - 4 = 22.

Given that:-

Number of posters bought by Jill on Tuesday = 8

Number of posters left on Thursday = 22

We can write,

Number of posters destroyed on Wednesday = (1/2)*8 = 4

Let the number of posters Jill had on Monday be p.

Hence, the equation for the posters is given by:-

Posters on Monday + Posters bought on Tuesday - Posters destroyed on Wednesday = Total posters on Thursday

It can be written as:-

p + 8 - 4 = 22

Solving the equation, we get

p + 4 = 22

p = 22 - 4

Step-by-step explanation:

Subtract 44 - 15=29

The first 3 pair of opposite integers are (-1,1),(-2,2) and (-3,3).

Given that,

We have to find the first 3 pairs of opposite integers.

Opposite integers means the "counting numbers" (sometimes known as integers), as well as zero, are integers. The pairs of integers known as opposite integers share the same absolute value, or, to put it another way, are equally spaced from zero. The numbers 10 and -10 are the opposites. The numbers 43 and -43 are the opposites.

So,

Keep in mind that our whole numbers are our integers. The negative and positive iterations of a number together are called a pair of opposite integers.

We get, the first 3 pair of opposite integers are (-1,1),(-2,2) and (-3,3).

Therefore, the first 3 pair of opposite integers are (-1,1),(-2,2) and (-3,3).

Answer:24 bags

Step-by-step explanation:

Using the given information, the number of bags created with  random seed packets is 16 complete bags of seeds and a remainder of 5 seed packets

The number of bags created achieved by division. This is a basic mathematical operator used in sharing items

Given information

Seed Type                                 Number of Packets

Aster                                                       95

Daisy                                                       160

Pansy                                                      70

Sunflower                                                 -

Wildflower                                                -

Adding the number of packets available gives

95 + 160 + 70 = 325 seed packets

Sharing them in a bag containing 20 seed packets each we divider the total number of seed packets by 20

= 325 seed packets / 20

= 16.25

Therefore 16 bags will be created and 5 will be remaining

There are 90 apples in the pile and the row has 4 fewer apples than the row below.

An arithmetic sequence is defined as an arrangement of numbers that is in a particular order.

The sum of an arithmetic sequence is the sum of the first n terms of the sequence as

Sₙ = n/2(2a+(n−1)d)

In arithmetic, here a₁ is the first term and sequence d represents the common difference.

Sum of the apples = 25 + 21 + 17 + 14 + 13 + 9

This series is in AP where a = 25 , d = - 4 and n = 6

As per the given data, the sum of apples would be as:

S₆ = 6/2(2×25+(6-1)×-4)

S₆ = 3(50 + 5×-4)

S₆ = 3(50 - 20)

Using the polynomial expression, the non-real solutions are x = (2 + i√26)/3 and  x = (2 - i√26)/3

Polynomial expressions are mathematical statements that are represented by variables, coefficients and operators

The equation of the polynomial expression is given as:

3x^3 + 14x^2 - 14x + 60 = 0

From the question, we have

Real solution = -6

Rewrite the above equation as

x = -6

Add 6 to both sides of the equation

So, we have

x + 6 = 0

The next step is to divide the polynomial equation 3x^3 + 14x^2 - 14x + 60 = 0 by x + 6 = 0

This is represented as

3x^3 + 14x^2 - 14x + 60/x + 6

Using a graphing calculator, we have

3x^3 + 14x^2 - 14x + 60/x + 6 = 3x^2 - 4x + 10

Next, we determine the solution of the quadratic expression 3x^2 - 4x + 10 using a quadratic formula

So, we have

x = (-b ± √(b² - 4ac))/2a

This gives

x = (4 ± √((-4)² - 4 * 3 * 10))/2 * 3

So, we have

x = (4 ± √-104)/6

This gives

x = (4 ± 2√-26)/6

Divide

x = (2 ± √-26)/3

Rewrite as

x = (2 ± i√26)/3

Split

x = (2 + i√26)/3 and  x = (2 - i√26)/3

Hence, the non-real solutions of the polynomial expression are x = (2 + i√26)/3 and  x = (2 - i√26)/3

The polynomial area of the framed picture is (27 + 2x) * (15 + 2x) and the value is 693 square units

The area of a shape is the amount of space on the shape

For most regular quadrilaterals, you multiply the side lengths to determine the area

The given parameters are

Width = 15

Length = 27

Also, we have

Length of the frame = x

This means that the area of the framed picture is

Area = (Length + 2 * Length of the frame) * (Width + 2 * Length of the frame)

Substitute the known values in the above equation

Area = (27 + 2x) * (15 + 2x)

In (a), we have

Area = (27 + 2x) * (15 + 2x)

As given in the question,

Number of free clues =3

Total number of clues used to escape from a room = 5clues

Out of these 5 clues, 3 clues are free to use. Hence these 3 clues do not result in any time change.

Hence total time elapsed after usage of 3 clues = 0

Each removes 5 minutes from your remaining time

Integer represents the total change in the time for the usage of 4th and 5th clue = 10 minutes

So overall change in timeline after consuming 5 clues = 10 minutes since each of the 4th and 5th clue results in decrease of 5 minutes each; thus effecting 10 minutes total time change (reduction)
