Answer:

The formula to get the circumference of a circle is [tex]C=2*\pi * r[/tex] but in this case we see that a diameter is being used therefore we can get rid of the 2 and the r because that is what the diameter and just replace d into there like this [tex]C=d*\pi[/tex].

We can then input the value and we get that [tex]C=3.142[/tex]

Answer:

The value of x = 11/10 or 1.1

Step-by-step explanation:

5x+3/-2 =4

=> 5x -3/2 = 4

=> 5x = 4 + 3/2

=> 5x = (8+3)/2

=> 5x = 11/2

=> x = 11/10 or 1.1

Answer: 972π in³

Step-by-step explanation:

  We will use the proper formula to solve for the volume of the sphere.

-> The radius (r) is half the diameter. 18 in / 2 = 9 in

V = [tex]\frac{4}{3}[/tex]πr³

V = [tex]\frac{4}{3}[/tex]π(9)³

V = [tex]\frac{4}{3}[/tex] * (9)³ * π

V = 972π in³

   The volume is 972π in³

Answer:

The commutative property of addition means that it does not matter what order in which you add numbers. You will get the same answer either way. It is represented as a + b = b + a, in which a and b are real numbers. However, the property is not limited to two numbers.

1) Rearrange terms

3 + 5m = 5m + 3

5m + 3 = 5m + 3

2) Subtract 3 from both sides

5m + 3 = 5m + 3

5m + 3 - 3 = 5m + 3 - 3

3) Simplify

- Subtract the numbers

5m + 3 - 3 = 5m +  3 - 3

5m = 5m + 3 - 3

- Subtract the numbers

5m = 5m + 3 - 3

5m = 5m

4) Subtract 5m from both sides

5m = 5m

5m - 5m = 5m - 5m

5) Simplify

- Combine like terms

5m - 5m = 5m - 5m

0 = 5m - 5m

- Combine like terms

0 = 5m - 5m

0 = 0

This means it has infinite solutions.

But the commutative property addition have been shown.

The constant should be added to form a perfect square trinomial will be 1/4. Then the correct option is D.

It's a polynomial with a value of zero. There exist polynomials of variable power 2, 1, and 0 terms. A quadratic equation is an equation with one statement in which the degree of the parameter is a maximum of 2.

The expression is x² + x.

Then the constant should be added to form a perfect square trinomial.

Then the constant will be

The square of the half of the coefficient of the variable x is to be added to make a perfect square.

Then the constant will be 1/4.

Then the perfect square will be

[tex]\rm \rightarrow x^2 + x + \dfrac{1}{4}\\\\\\\rightarrow x^2 + 2 \times \dfrac{1}{2} x + \left (\dfrac{1}{2} \right )^2\\\\\\\rightarrow \left (x + \dfrac{1}{2} \right)^2[/tex]

Answer:

664 ft²

Step-by-step explanation:

The rectangular yard has dimensions 36 ft by 55 ft.

The area of the yard is 36 ft × 55 ft = 1980 ft²

The walkway inside the fence is 4 ft wide. The area inside the walkway has dimensions

36 ft - 2 × 4 ft = 28 ft

55 ft - 2 × 4 ft = 47 ft

The area of the rectangle inside the walkway is 28 ft × 47 ft = 1316 ft²

The area of the walkway is the difference between the total area enclosed by the fence and the rectangle inside the walkway.

area of walkway = 1980 ft² - 1316 ft² = 664 ft²

The length of PC is 3.

If a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.

Given: BA = 5, AP = 4 and DP = 12.

PB= BA+AP= 9

Using tangent- secant theory

PA*PB= PC*PD

4*9= PC* 12

36= 12PC

PC= 36/12

PC= 3

Hence, length of PC is 3.

The volume of the conical enclosure is approximately 871 ft³.

The density of the birds in the enclosure is number of birds / volume

The number of bird per cubic ft is 0.04822043628 birds per cubic foot

volume of a cone = 1 / 3 πr²h

where

Therefore,

v = 1 / 3 × 3.14 × 8² × 13

v = 1 / 3 × 3.14 × 64 × 13

v = 2612.48 / 3

v = 870.826666667

v = 870.83 ft³

The density of the birds in the enclosure is the mass of the birds divided by the volume of the enclosure.

The probability that the total of the two numbers is more than 32 = [tex]\frac{2}{5}[/tex]

"Probability is a branch of mathematics which deals with finding out the likelihood of the occurrence of an event."

P(A) = n(A)/n(S)

where,  n(A) is the number of favorable outcomes, n(S) is the total number of events in the sample space.

[tex]^nC_r=\frac{n!}{r!(n-r)!}[/tex]

For given question,

We have been given five number cards.

Two of the five cards are picked at random.

Using combination formula the possible number of outcomes would be,

[tex]^5C_2\\\\=\frac{5!}{2!(5-2)!} \\\\=10[/tex]

So, n(S) = 10

Let event A : the total of the two numbers is more than 32

A = {(19, 14), (19, 22), (13, 22), (14, 22)}

So, n(A) = 4

Using the formula for probability,

[tex]\Rightarrow P(A)=\frac{n(A)}{n(S)} \\\\\Rightarrow P(A)=\frac{4}{10}\\\\\Rightarrow P(A)=\frac{2}{5}[/tex]

Therefore, the probability that the total of the two numbers is more than 32 = [tex]\frac{2}{5}[/tex]

Step-by-step explanation:

2 times 4 is 8

Step-by-step explanation:

remember, when multiplying the same base with different exponents, we add the exponents.

when putting exponents to the power of exponents, we multiply the exponents (as simplified shortcut of all the additions we would actually have to do).

((-3)²)⁴ = (-3)⁸

in "slow motion" :

The relative frequency of students who purchased popcorn in a movie at the local theater is 35.89%.

Relative frequency of a event is the measure of something happens relative to the total outcomes of that event.

The relative frequency can be given as,

[tex]f_r=\dfrac{f}{n}[/tex]

Here, (f) is the frequency of the number of times data occurred in an event and (n) is the total number of outcomes.

The relative frequency can also be defined as, it is the ratio of subgroup frequency to the total frequency of any event.

One weekend, 156 students went to see a movie at the local theater. Their popcorn and drink purchases were recorded in the two-way table shown.

The number of student who purchased popcorn are 56 while the total number of students is 156. Thus, the relative frequency is,

[tex]f_r=\dfrac{56}{156}\\f_r=0.3589\\f_r=35.89\%[/tex]

Answer:

8 78 86

120 140 260

Step-by-step explanation:

You can solve this problem easily by looking at the total amounts compared to the information you already have. Once you do this, you can simply subtract them from each other to find the first two empty boxes, then you can just add across for the totals for the boxes on the right.

The complete two-way table looks like:-

.                                                        Identified As:

                                               Savers   Spenders   Total

                        Savers              112           62           174

Wants to be:    Spenders             8            78             86

                        Total                 120          140           260

A two-way table displays the frequencies or relative frequencies of two categorical variables. One category is represented by rows, while the other is represented by columns.

In the question, we are asked to complete the two-way table as per the given information.

In the first row, second column:

The box needs the data for the number of spenders who want to become savers.

In the provided information, we have been told that of the 140 people who identified themselves as spenders, 78 said they would continue being spenders, while the rest said they would like to be savers.

Thus, the number of spenders who want to be savers = 140 - 78 = 62.

Hence, entry is 62.

In the first row, third column:

The box needs the data for the number of people who now want to continue as savers, or become one.

This can be shown as the sum of the first two readings of the row.

Thus, the total number of people who now want to continue as savers, or become one = 112 + 62 = 174.

Hence, entry is 174.

In the second row, first column:

The box needs the data for the number of savers who want to become spenders.

In the provided information, we have been told that of the 120 people who identified themselves as savers, 112 said they would continue being savers, while the rest said they would like to be spenders..

Thus, the number of savers who want to be spenders = 120 - 112 = 8.

Hence, entry is 8.

In the second row, third column:

The box needs the data for the number of people who now want to continue as spenders, or become one.

This can be shown as the sum of the first two readings of the row.

Thus, the total number of people who now want to continue as spenders, or become one = 8 + 78 = 86.

Hence, entry is 86

Thus, the complete two-way table looks like:-

.                                                        Identified As:

                                               Savers   Spenders   Total

                        Savers              112           62           174
