129 many music on his Computer if Jan has 516 when on Jan's computer, there are four times as many songs as there are on Ian's.

Given that,

On Jan's computer, there are four times as many songs as there are on Ian's.

We have to find Ian has how many music on his Computer if Jan has 516.

We know that,

Let x  be the number of songs lan has.

Since Jan has 4 times as many songs than lan then multiply x by 4.

Then equate this expression to 516.

4x=516

Divide 4 on both sides

4x/4=516/4

x=129

Therefore, 129 many music on his Computer if Jan has 516 when on Jan's computer, there are four times as many songs as there are on Ian's.

(b) The product of any two terms of the sequence is present in the sequence.

A geometric sequence is one where each phrase is obtained by multiplying the term before it by the same number.

Formula to find nth term of geometric sequence is aₙ = a₁ rⁿ⁻¹. The common ratio is expressed as the value r.

Given that,

The nth term of the geometric sequence uₙ = 3ⁿ.

(a)

The first term of the sequence u₁ = 3¹

Second term of the sequence u₂ = 3² = 9

Third term of the sequence u₃ = 3³ = 27

And the fourth term of the sequence u₄ = 3⁴ = 81

The four terms of the sequence are 3, 9, 27, 81.

(b)

To prove that product of two term is also present in the sequence.

Product of first two terms = 3 x 3² = 3 x 9 = 27

27 is present in the sequence.

Further, product of next two terms,

9 x 27 = 243 = 3⁵

Answer:

13 Hurdles

Step-by-step explanation:

If a horse galloped along seven and three sevenths miles of trail and hurdles spaced evenly throughout the trail every four sevenths of a mile then there are 13 such hurdles after solving all the fractions.

Given that a horse galloped along seven and three sevenths miles of trail and hurdles spaced evenly throughout the trail every four sevenths of a mile.

We are required to find the number of hurdles. All the values are given in fractions.

Ability of horse to gallop=7+3/7

=(49+3)/7

=52/7

Distance between two hurdles=4/7

Number of hurdles=52/7/4/7

=52*7/4*7

=52/4

=13 hurdles

Hence if a horse galloped along seven and three sevenths miles of trail and hurdles spaced evenly throughout the trail every four sevenths of a mile then there are 13 such hurdles after solving all the fractions.

The difference between the largest and smallest geometric numbers is 840.

Assume that the largest geometric number starts with a 9.

We know that the common ratio must be a rational of the form k/3 for some integer k, because a whole number should be attained for the 3rd term as well. When k = 1, the number is 931.

When k = 2, the number is 964. When k = 3, we get 999, but the integers must be distinct.

By the same logic, the smallest geometric number is 124.

The largest geometric number is 964 and the smallest is 124. Thus the difference is 964 - 124 = 840.

Hence, the difference between the largest and smallest geometric numbers is 840.

If 675 workers work for 3 hours and can produce 11198.25 widgets then the constant of proportionality is  5.53 .

In the question,

it is given that ,  

the number of widgets production varies with the  number of workers and the time that they have worked ,

let the number of workers be "w" and

let the number of time they worked be "t" ,

let the number of widgets produced be "n".

So , the equation becomes

n ∝ w × t

n = k × t × w

Substituting the values of w  = 675 , t = 3 and n = 11198.25

we get ,

11198.25 = k × ×675 × 3

k = 11198.25/2025

k = 5.53

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the event's impossibility and 1 indicates certainty. An event's likelihood of occurring increases with its probability.

What is Probability?

Probability is the measure of the likelihood of a certain event or outcome happening. It is expressed as a number between 0 and 1, where 0 means the outcome or event is impossible and 1 means the outcome or event is certain. Probability can be used to calculate the chances of certain outcomes occurring in a variety of situations. Probability can be used to determine the likelihood of events happening in games of chance, in business and finance decisions, in science and medicine, and in a variety of other contexts. Probability can also be used to help us make decisions and understand the relationships between different events.

By using the quadratic equation that can be written with the given information:

x² -7x + 10 = (x - 5)*(x - a)

We will see that the length is:

L  = x - 2

Remember that for a rectangle of length L and width W, the area is given by the product:

A = L*W

Here we know that:

The area is: x² -7x + 10

The width is: x -5

The length will be another factor of the quadratic equation, and we know that it should be of the form:

(x - a)

Using the area formula, we will get:

x² -7x + 10 = (x - 5)*(x - a)

Expanding the right side we get:

x² -7x + 10 = x² -5x -ax + 5a

x² -7x + 10 = x² + (-5 - a)*x + 5a

Comparing like terms, we can see that:

-5 - a = -7

5a = 10

a = 7 - 5 = 2

a = 10/5 = 2
