What is a Sphere?

A sphere is a geometrical object that resembles a two-dimensional circle in three dimensions. In three-dimensional space, a sphere is a collection of points that are all located at the same r-distance from a single point. The radius of the sphere is denoted by the letter r, and the specified point represents its center.

1 cm = 10mm

6 cm = 60mm

Ball diameter is 5 mm.

|-7| and |7|

what does the | mean?

Answers

Absolute value.

Basically, you neglect the sign on the number and only consider the magnitude.

Consider the following examples:
|-7| = 7
|7| = 7
|2-3| = |-1| = 1
|3-2| = |1| = 1
The | means how far the number is away from zero. For example, |-2| is 2 numbers away from zero, so it’s two

Answers

Given:

If you borrow $100, you will have an interest of $10.

Asked: How much do you owe at the end of four weeks?

Solution:

To solve this problem, we need to find the rate, r.

According to the given, we can get the rate by:

$100 x rate = $10

rate = $10/$100

rate = 0.10

Now, if you borrow $1100, you will pay at the end of four weeks the amount of:

$1100 x 0.10 = $110

a drawer contains a mixture of red socks and blue socks, at most 1991 1991 in all. it so happens that, when two socks are selected randomly without replacement, there is a probability of exactly 1 2 12 that both are red or both are blue. what is the largest possible number of red socks in the drawer that is consistent with this data? (1991,

Answers

The largest possible number of red socks in the drawer that is consistent with this data is 990.

To solve the given question, we will form equations according to the given data including a known and an unknown variable.

Let r be the number of socks that are red, and t be the total number of socks.

We get,

2(r(r-1)+(t-r)(t-r-1))=t(t-1)

Expanding the left hand side and the right hand side

we get,

4r^2-4rt+2t^2-2t = t^2-t

moving the terms, we will get that

4r^2-4rt+t^2 = t

We notice that the left side is a perfect square.

(2r-t)^2 = t

Thus t is a perfect square.

And, the higher t is, the higher r will be. So, we should set

t = 44^2

= 1936

we see, 2r-1936 = 44

We will use the positive root, to get that

2r-1936 = 44,

2r = 1980

r = 990

Therefore, we can conclude that the largest possible number of red socks in the drawer that is consistent with this data is 990.

Answers

Option (C) is correct which is the equation 4 w + ( − 4 p ) = 8 . 00 is the result of subtracting the second equation in the system from the first equation.

Mai and Tyler are selling items to earn money for their elementary school.

Mai sells 14 wreaths and 3 potted plants and the school earns $70.50. Mathematically we can write,

14 w + 3 p = 70.50                          equation 1

Tyler sells 10 wreaths and 7 potted plants and the school earns $62.50. Mathematically we can write,

10 w + 7 p = 62.50                           equation2

equation 1 - equation 2 , we get

4 w + ( - 4 p ) = 8.00

which is the required equation.

We can conclude that the equation 4 w + ( − 4 p ) = 8 . 00 is the result of subtracting the second equation in the system from the first equation

So, option (C) is correct.

In order for the ratio of AP to PB to be 3/2, the coordinates of point P along the directed line segment AB are (14/5, -1).

What exactly is a section formula?

The section formula returns the coordinates of a point that divides the line connecting two points in a ratio, either internally or externally.

Section formula is given as follows:

[tex](\frac{mx_{2 }+nx_{1} }{m+n} , \frac{my_{2} +ny_{1} }{m+n})[/tex]

In math, how do you find coordinates?Start at the point and trace a vertical line up or down to the x-axis. There you have your x-coordinate. Then repeat the process, but this time follow a horizontal line to find the y-coordinate.

It is given that the coordinates of the points A and B are A(-2, -4), B(6, 1) and   AP/PB = 3/2

Let the coordinates of the point P be (a, b).

By using section formula,

(a, b) = [tex](\frac{mx_{2 }+nx_{1} }{m+n} , \frac{my_{2} +ny_{1} }{m+n})[/tex]

(a, b) =  [tex](\frac{3(6)+2(-2)}{3+2} , \frac{3(1) +2(-4)}{3+2} )[/tex]

By solving a linear equation we will see that the value of x is x = $4.00

How to get the cost of the candy?

We know that a store owner mixes 2 Ib of candy that costs x dollars per pound with 3 Ib of candy that costs $1.50 per pound. She sells the mix for $2.50

The total amount of the mix is:

2lb + 3lb = 5lb, now, the total cost at the beginning must be the same as the final cost, so we can write the equation:

2*x + 3*$1.50 = 5*$2.50

Now we can solve this linear equation for x:

2*x = 5*$2.50 - 3*$1.50 = $8.00

x = $8.00/2 = $4.00

example: suppose that the probability that an item produced by a certain machine will be defective with probability 0.1. find the probability that a sample of 10 items will contain at most 1 defective item.

Answers

The probability that a sample of 10 items will contain at most 1 defective item is 0.7361

Consider X to denote the number of defective items which follows binomial distribution with sample size, n equals to 10.

The probability p of an item produced by a certain machine will be defective is 0.1.

Therefore, the probability q of an item produced by a certain machine will not be defective is:

(1−0.1)

=0.9

The probability of at most one defective item can be calculated as follows:

[tex]P(X\leq 1)=P(X=0)+P(X=1)\\[/tex]

[tex]=^{10} C_{0} p^{0} (1-p)^{10} +^{10} C_{1} p^{1}(1-p)^{9}[/tex]

[tex]=(0.9)^{10} +10(0.1)(0.9)^{9}[/tex]

[tex]=0.7361[/tex]

Converting each of the question mentioned decimal into fractions in their simplest form, we get,

(i) 0.6 with 6 recurring = (2/3)

(ii) 3.405 with (405) recurring = (378/37)

(iii) 0.75 with (75) recurring = (25/33)

(iv) 0.3 with 3 recurring = (1/3)

As per the question statement and the attached reference along with the question, we are provided with four recurring decimal values.

We are required to convert each of the decimal values into fractions in their simplest form.

Starting with (i), 0.6 with 6 recurring = 0.66666...

Now, let [x = 0.6666...]

Or, [10x = 6.6666...]

Or, [(10x - x) = (6.6666...) - (0.6666...)]

Or, (9x = 6)

Or, [x = (6/9)]

Or, [x = (2/3)]

Or, [0.6666... = (2/3)]

Similarly for (ii), 3.405 with (405) recurring = 3.405405405405...

Now, let [x = 3.405405405...]

Or, [1000x = 3405.405405405...]

Or, [(1000x - x) = (3405.405405405...) - (3.405405405...)]

Or, (999x = 3402)

Or, [x = (3402/999)]

Or, [x = (378/37)]

Or, [3.40540405... = (378/37)]

Coming to (iii), 0.75 with (75) recurring = 0.757575...

Now, let [x = 0.757575...]

Or, [100x = 75.757575...]

Or, [(100x - x) = (75.757575...) - (0.757575...)]

Or, (99x = 75)

Or, [x = (75/99)]

Or, [x = (25/33)]

Or, [0.757575... = (25/33)]

Finally coming to (iv), 0.3 with (3) recurring = 0.333...

Now, let [x = 0.333...]

Or, [10x = 3.333...]

Or, [(10x - x) = (3.333...) - (0.333...)]

Or, (9x = 3)

Or, [x = (3/9)]

Or, [x = (1/3)]

Or, [0.333... = (1/3)]

Recurring Decimal: A recurring decimal is a decimal in which, a particular digit or sequence of digits repeat(s) itself indefinitely after a certain point.Fractions: Any mathematical quantity which is not a whole number, and is expressed as a quotient of two numbers, one at the numerator (top) and the other at the denominator (bottom), separate by a (/) in between, is known as a fraction.
