The population of Halifax is about 1000 times as greater as the population of Balnamore.

The process of defining similarities between two numbers and determining which number is greater, smaller, or equal to the other number is known as comparing numbers.

Here we will compare the numbers by using counting.

We know that a number with more digits is typically greater than one with fewer.

i) The population of Birmingham is about 10 times as big as the population of Halifax because the population of Birmingham is 9,00,000 is greater than Halifax's 90,000 by 10.

ii) The population of London is about 1000 times as big as the population of Longton. Because the population of London has three more zero digits than the population of Longton.

iii)The population of Halifax is about 1000 times as big as the population of Balnamore. Because the population of Halifax has three more zero digits than the population of Balnamore.

The solution of the equation 5x/4 - 3/x= 1/4 for x is (1+√241)/10 or (1 -√241)/10.

According to the given question.

We have an equation 5x/4 - 3/x= 1/4.

As we know that, an equation is a condition on a variable such that two expressions in the variable should have equal value.

Therefore, the solution of the equation 5x/4 - 3/x= 1/4 for x is given by

5x/4 - 3/x= 1/4

⇒ ( 5x^2 -12) /4x  = 1/4

⇒ 5x^2 - 12   = (1/4)4x                 (multiplying both the sides by 4x)

⇒ 5x^2 - 12 = x

⇒ 5x^2 - x -12 = 0

⇒ x = [tex]\frac{1\pm\sqrt{1+240} }{10}[/tex]

⇒ x = (1+√241)/10 or (1 -√241)/10

Hence, the solution of the equation 5x/4 - 3/x= 1/4 for x is (1+√241)/10 or (1 -√241)/10.

How should this model be completed to represent 820 ÷ 17? Enter your answers by filling in the boxes. I'm in 5the BTW

The equation of to represent the two unknowns y and x is undefined hence it can be said not to be existing.

Equation of a straight line is the equation of the form

y = mx + c

y and x are the unknown variables

m is the slope

c is the intercept in the y axis

The equation given in the problem is a special type which is a vertical line

A vertical line has no intercept on the y axis hence c =0/ This reduces the equation of a straight line to

y = mx + c

at c = 0 we have:

y = mx + 0

y = mx

The slope of the vertical line is undefined. From first principles we have that slope is

m = change in y / change in x

for a line to be vertical the change in x is at the lowest absolute value and the smallest absolute number is zero. note negative number is not inclusive.

Therefore the slope at change in x = 0 represents a vertical line which is

m = change in y / change in x

m = change in y / 0

m = undefined

so y = undefined

check using calculator any number divided by zero gives error which is defined mathematically to be undefined,

We can conclude that the relationship between y and x from the graph is undefined.

The probability of getting a number greater than 1 is 5/6

What is the formula of Probability?

The probability formula is defined as the possibility of an event to happen is equal to the ratio of the number of favourable outcomes and the total number of outcomes.

Probability of event happen P(E) = Number of favourable outcomes / Total number of outcomes.

The possible outcomes when a die thrown is {1, 2, 3, 4, 5, 6}. Therefore, the number of possible outcomes of a die is 6.

Now, the numbers greater than 1 between 1 to 6 are P{2, 3, 4, 5, 6} then the number of favourable outcome is 5.

Therefore, probability P of getting a number greater than 1 is:

P = 5/6

Hence, the probability of getting a number greater than 1 is 5/6

The final amount when $10,000 is invested for 3 years at 3% the interest is compounded continuously is  $10,942

What is compound interest ?

A compound interest rate is a rate of interest calculated on both the amount saved and the interest earned on it.

In the given question the expression to calculate amount is given as :

A = Pe^(rt)

where,

P = principle amount that is $10,000

r = rate of interest that is 3%

t = time period that is 3 years

Now, calculating Amount by substituting the above value in the formulae :

A = Pe^(rt)

A = 10000 e^(0.03 x 3)

A = 10000 e^(0.09)

A = 10000 x 1.0942

A = $10,942

Therefore, the final amount when $10,000 is invested for 3 years at 3% the interest is compounded continuously is $10,942

The algebraic method for solving simultaneous linear equations is the substitution method. The value of one variable between one equation is exchanged in the second equation, as the name implies.

First, we will remove bb from the second equation and then substitute it in the first equation:

b= −7 + 2a

Explanation: Let's say, two triangles both have the same angle, say 90 degrees. They also share two side lengths. Both triangles have a side length of 9 and another side length of 8.

The two triangles, sharing all these properties, must be congruent. This congruency is proven by SAS.

45 inch is shorter in length.

Feet is a unit of measuring length as per the US standard system of measurement and centimeters is the unit of length measurement as per the metric system. Feet is abbreviated as 'ft'.

Inches is another measurement of length . It is a unit used for measuring length, approximately equal to 2.54 centimetres, sometimes shown by the symbol ″

1 feet = 12 inches which means feet is a bigger unit than inch.

So 4 feet 1/2 inch = 54 inches

54 inches is greater than 45 inches,

Step-by-step explanation:

The slope of the line is 0 since the y-value doesn't change, meaning it is a horizontal line.

Answer:

Slope ⇒ 0

Step-by-step explanation:

The formula to find the slope of a line is:

[tex]m = \frac{y_1-y_2}{x_1-x_2}[/tex]

We can use the given two coordinates of the line to find the slope.

( 1, -7 ) ⇒ ( x₁, y₁ )
