What is the highest common factor of 39375 and 779625?

Answer:

=-1.66

Step-by-step explanation:

The numbers are 8 and 24.

Let the smaller number be x.

Larger number = 3x

Therefore, the expression will be:

3x - 10 = x + 8

Collect like terms

3x - x = 8 + 10

2x = 18

Divide

x = 18/2

x = 9

The bigger number will be:

3x = 3 × 8 = 24

The expression to find the temperature at the end of the day is Morning temperature + (Change in temperature) and we get the temperature as -24 degree Fahrenheit.

Given,

The Morning temperature = 15°F

Change in temperature during day time = fall by 39 degree Fahrenheit

The temperature of the end of the day:

Morning temperature + (change in temperature)

Fall by 39° = decrease in temperature by 39° = - 39°

Therefore,

Substitute the values in the expression:

That is,

15°F + (-39°F)

15°F - 39°F

= - 24°F

Therefore, the expression to find the temperature at the end of the day is Morning temperature + (Change in temperature) and we get the temperature as -24 degree Fahrenheit.

The expression is given as

2x^2

From the question, we have the values of the x and y to be

x = 5 and y = 2

Substitute x = 5 and y = 2 in the expression 2x^2

So, we have

Answer:

line J and line L are parallel so C.

The parallel line are j and l.

Hence the correct answer is c.

Given are four lines that have been graphed on the same coordinate grid.

We need to check which of these are parallel to each other.

To determine which lines are parallel to each other, we need to compare their slopes. Parallel lines have the same slope.

The general form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept.

Let's identify the slopes of the given lines:

Line j: y = (2/3)x + 1/2

Slope of j: 2/3

Line k: y = (1/2)x + 2/3

Slope of k: 1/2

Line l: y = (2/3)x + 3/2

Slope of l: 2/3

Line m: y = (3/2)x + 1/2

Slope of m: 3/2

Now, let's see which lines have the same slope:

A. k & m - The slopes are different (1/2 and 3/2). These lines are not parallel.

B. k & l - The slopes are different (1/2 and 2/3). These lines are not parallel.

C. j & l - The slopes are the same (2/3). These lines are parallel.

D. j & m - The slopes are different (2/3 and 3/2). These lines are not parallel.

The give expression can be written in the simplest form by solving the exponents.

The rules applicable to the expression are rule for negative exponent and power rule of exponents. Either one can be used first. In this case we will multiply the exponents and then solve for the negative exponent.

According to the power rule of exponents, when an exponential expression is raised to a new power, the exponents are multiplied i.e. (a^x)^y=a^xy

(x^2/3)^-3=x^(2/3)*-3=x^-2

According to the rule of negative exponents, the term with the negative exponent can be solved by expressing it as a reciprocal of the term i.e. a^-x=1/a^x

x^-2=1/x^2

They spent 1/70 of their monthly income on other things.

The family spent GH¢60,000 on clothing.

The monthly income of the family is GH¢168,000.

What is Fraction?

The number is expressed as a quotient in which the numerator is divided by the denominator is called fraction.

Since, The family spend;

On food = (3/7)*x

On clothing = (5/14)*x

On rent = (1/5)*x

Let the family's monthly income = x

Now, To find the fraction of the family's income is spent on other things, we can assume that y is spent on other things, then we should have;

(3/7)*x + (5/14)*x + (1/5)*x + y*x = x

We can divide both sides by x, we get:

(3/7) + (5/14) + (1/5) + y = 1

Now, we can solve this for y as;

3/7 + 5/14 + 1/5 + y = 1

6/14 + 5/14 + 1/5 + y = 1

(6 + 5)/14 + 1/5 + y = 1

11/14 + 1/5 + y = 1

The smallest common factor of 14 and 5 =  14*5 = 70

So, we can multiply in the first fraction by 5/5 and the second by 14/14,

(5/5)*(11/14) + (14/14)*(1/5) + y = 1

55/70 + 14/70 + y = 1

69/70 + y = 1

y = 1 - 69/70

y = 1/70

Hence, They spent 1/70 of their monthly income on other things.

And, On a particular month, the family spends  GH¢2,400 on other things, then if the monthly income is x, we have:

(1/70)*x = GH¢2,400

x = 70* GH¢2,400

x = GH¢168,000

So, The monthly income of the family is GH¢168,000

And, we know that they spend (5/14)*x on clothing,

Then this month they spent on clothing,

⇒ (5/14)*GH¢168,000 = GH¢60,000

So, They spent 1/70 of their monthly income on other things.

The family spent GH¢60,000 on clothing.

The monthly income of the family is GH¢168,000.

The total number of customers = 20

Of the 20 customers,

4 have enough cash to pay for their meal

16 have a credit card and

3 have enough cash and a credit card.

Event A is the probability that a customer has enough cash

Event B is the probability that a customer has a credit card.

P (B) =16 / 20 = 4 / 5, this is the probability that a customer has a credit card.

P (A and B) = 3 / 20, this is the probability that a customer has enough cash and a credit card.

To find the probability that a customer has enough cash or a credit card :

The formula used is P(A or B) = P(A) + P(B) - P(A∪B)

P (A or B) = P(A) + P(B) - P (A and B)

The inverse function of  f(x) = √x + 2 would be f⁻¹(x) = x² - 2.

The domain of the function would be {x ∈ R, x ≥ −2}.

The range would be {y ∈ R, y ≥ 0}.

The inverse function returns the original value for which the output of a function was given. When it comes to functions, f and g are inverse, with f(g(x)) = g(f(x)) = x. A function that is made up of its inverse returns the original value.

Considering f(x) = y, to find the inverse function, the x and y values are switched giving the new equation of

x = √y + 2

Simplifying the above equation, we get

x - 2 = √y

x² - 2 = y

x² - 2 = y is the inverse of the function f(x)=√x+2

The domain of the function would be all x, such that x + 2 ≥ 0, or x ≥ −2.

Hence it is {x∈R, x ≥ −2}

For range, consider y =√x + 2.

Since√x+2 ≥ 0, it is obvious that y ≥ 0.

The range would be {y ∈ R, y ≥ 0}
