[tex]4500 = 1200 + 300m[/tex]

Step-by-step explanation:

Given

[tex]Total = 4500[/tex]

[tex]Base\ Amount = 1200[/tex]

[tex]Payment = 300[/tex] monthly

Required

Write an expression to determine the number of months

The total can be expressed using:

[tex]Total = Base\ Amount +Payment * Number\ of\ months[/tex]

Substitute value for each term

[tex]4500 = 1200 + 300 * m[/tex]

[tex]4500 = 1200 + 300m[/tex]

Answer:

7

Step-by-step explanation:

Natural numbers , Real numbers ,Whole numbers ,Integers , Rational numbers

sqrt(49) = 7

So this number is in the set of...

The set of natural numbers is {1,2,3,...} and the set of whole numbers is {0,1,2,3,...}. Basically we just added in 0. Integers will be similar but we now have negative values too {..., -3, -2, -1, 0, 1, 2, 3, ...}

Rational numbers are anything of the form a/b with a,b being integers. In other words, if we can write the number as a fraction of two integers, then we have a rational number. In the case of 7, we have 7 = 7/1, so it is rational.

The set of real numbers includes every number type you have learned of so far (natural, whole, integer, etc). If you haven't learned about imaginary or complex numbers yet, then every number your teacher will go over is a real number.

Answer:

Step-by-step explanation:

Given the system of homogeneous equations

x1 + 2x2 - 3x3 = 0  ................. 1

4x1 + 7x2 - 9x3 = 0 ................... 2

-x1 - 3x2 + 6x3 = 0..................... 3

First we will reduce the equation to two equations and two unknowns;

add equation 1 and 3;

2x2-3x2 +(-3x3+6x3) = 0

-x2 + 3x3 = 0

x2 = 3x3 .......... 4

Multiply equation 3 by 4 and add to equation 2;

equation 3 * 4 will give;

-4x1 - 12x2 + 24x3 = 0..................... 5

add equation 5 to equation 2;

7x2-12x2-9x3+24x3 = 0

-5x2 - 15x3 = 0 .......... 6

5x2 = 15x3

x2 = 3x3

Let x2 = k

From equation 4;

k = 3x3

x3 = k/3

substitute x2 = k and x3 = k/3 into equation 1 to get x1 in terms of k

From 1, x1 + 2x2 - 3x3 = 0

x1+2k-3(k/3) = 0

x1 +2k-k = 0

x1 +k = 0

x1 = -k

Writing the answer in vector form will give (x1. x2. x3) = (-k, k, k/3)

k(-1, 1, 1/3)

Hence the answer to the system of equation in vector form is k(-1, 1, 1/3) where k is any constant.

Answer:

x=108'

y=25'

Step-by-step explanation:

180 = 72+x

so,

x = 180-72

  = 108'

x = 5y-17 ( but we know x is 108')

so 108 = 5y -17

108+17 = 5y

5y = 125

y = 25

Answer:

x = 108 degree

y = 25 degree

Sample study

Step-by-step explanation:

Sample study is a type of statistical study that is done by taking samples from respondents for any research purpose.

In this type of statistical study, a group of people are selected and asked some questions or data collected.

The type of statistical study that Vishal used was Sample Study because he collected data from a group of respondents to arrive at a hypothesis.

Vishal study of relationship between people's age & musical preferences is 'Observational Statistical Study'

Given : Vishal approached all people in city, enquired willing ones about age & musical preferences, & analysed conclusion thereafter.

Vishal used Observational Statistical Study, as :

Vishal collects sample from his city & studies them as it is, without any artificial intervention. Hence this natural enquiry based study of age & musical preferences is Observational Study

Did this help?!?!?

Answer:

x < 3

Step-by-step explanation:

5x - 4 < 2x + 5

Subtract 2x from both sides

5x - 4 - 2x < 2x + 5 - 2x

5x - 2x - 4 < 2x - 2x + 5

3x - 4 < 0 + 5

3x - 4 < 5

Add 4 to both sides

3x - 4 + 4 < 5 + 4

3x < 9

Divide both sides by 3

3x/3 < 9/3

x < 3

Answer:

see below

Step-by-step explanation:

given:

LCM(a,b) = 20160, a=60

find:

smallest possible value of b

solution;

60, b = 20,160

b = 20,160 / 60

b = 336

60 x 336 = 20,160

= 2⁶ x 3² x 5 x 7

= (2² x 3 x 5) x (2⁴ x 3 x 7)

= (60) x (336)

LCM(60,336) = 1680

consider the 2² x 3 to get the prime number:

= 336 x 12

= 4032

therefore,

LCM(60,4032) = 20160

The smallest possible value of b is 336.

Prime Factorization is defined as any number that may be expressed as a product of prime numbers that has been said to be prime factorized. Any integer with exactly two factors 1 and the number itself. is said to be a prime number.

We have been given that

LCM(a,b) = 20160 and  a = 60

We have to determine the smallest possible value of b

Since the product of two numbers equals the product of their HCF and LCM.

⇒ 60 × b = 20,160

⇒ b = 20,160 / 60

⇒ b = 336

⇒ 60 × 336 = 20,160

We need to write 20160 as the product of its prime factors, which is 20160.

⇒ 2⁶ × 3² × 5 × 7

⇒ (2² × 3 × 5) x (2⁴ × 3 × 7)

⇒ (60) × (336)

⇒ LCM(60,336) = 1680

Therefore, the smallest possible value of b is 336.
