There are 11 prime dates in it.

The prime numbers between 1 and 30 are 1, 2,3,5,7,11,13,17,19,23,29

Relative prime:

Two integers are relatively prime (or coprime) if there is no integer greater than one that divides them both (that is, their greatest common divisor is one). For example, 12 and 13 are relatively prime, but 12 and 14 are not.

Hence There are 11 prime dates in the month of June.

Answer: 10

Step-by-step explanation:

Since exactly 1 in every $n$ consecutive dates is divisible by $n$, the month with the fewest relatively prime days is the month with the greatest number of distinct small prime divisors. This reasoning gives us June ($6=2\cdot3$) and December ($12=2^2\cdot3$). December, however, has one more relatively prime day, namely December 31, than does June, which has only 30 days. Therefore, June has the fewest relatively prime days. To count how many relatively prime days June has, we must count the number of days that are divisible neither by 2 nor by 3. Out of its 30 days, $\frac{30}{2}=15$ are divisible by 2 and $\frac{30}{3}=10$ are divisible by 3. We are double counting the number of days that are divisible by 6, $\frac{30}{6}=5$ days. Thus, June has $30-(15+10-5)=30-20=\boxed{10}$ relatively prime days.

The area of the composite shape cannot be determined without further information or a diagram provided.

To fully factor the given expressions:

(a) 12a² + 75 can be factored by finding the greatest common factor (GCF) and applying the difference of squares (DOS):

GCF: The GCF of 12a² and 75 is 3.

DOS: We can rewrite 75 as (5²)(3), so the expression becomes:

3(4a² + 25).

(b) 6x² + 18x - 24 can be factored by finding the GCF and using the process of factoring by grouping:

GCF: The GCF of 6x², 18x, and -24 is 6.

Factoring by grouping: We group the terms as follows:

6x² + 18x - 24 = 6(x² + 3x - 4).

Now we need to factor the quadratic expression in the parentheses. We can use the product and sum method or the quadratic formula to find the factors:

The factors of x² + 3x - 4 are (x + 4)(x - 1).

Answer: \(12\sqrt{5}\)

Step-by-step explanation:

\(3\sqrt{88}\)

88 can be rewritten as 8 x 10 and 8 can be rewritten as \(2^2*2\) making a 2 come out of the root.

\(3\sqrt{2^2*2*10}\\ 3*2\sqrt{2*10}\\6\sqrt{2*10}\)

10 can be rewritten as 2 x 5.

\(6\sqrt{2*2*5}\)

2*2 can also be rewritten as \(2^2\) making a 2 come out of the root.

\(6\sqrt{2^2*5}\\ 6*2\sqrt{5}\\ 12\sqrt{5}\)

Answer:

the answer is 50/9

Step-by-step explanation:

5 : 9/10 = 5 : 10/9 = 5×10/9 = 50/9

The number 5 divided by the fraction \(\dfrac{9}{10}\) gives the mixed fraction \(5\dfrac{5}{9}\).

In mathematics, a fraction is an expression that shows a portion or a division of a whole number. It's applied to portray numbers that are not whole numbers or integers. A fraction consists of two factors, that are:

1. Numerator: The numerator is the number on the top of the fraction. It represents the quantity or proportion of the total being considered.

2. Denominator: The denominator is the number at the bottom of the fraction. It represents the complete number of equal parts into which the total is divided.

\(5\ \div\ \dfrac{9}{10}\\= 5\ \times\ \dfrac{10}{9}\\= \dfrac{50}{9}\\\\= 5\dfrac{5}{9}\)

Thus, the fraction obtained by dividing 5 by \(\dfrac{9}{10}\) is \(5\dfrac{5}{9}\).

The slope of the line between the two points is - 2 / 3.

The slope of a line is the change in y coordinate with respect to the change in x coordinate.

The slope of a line is rise over run.

The slope of a line can be express as follows:

slope = y₂ - y₁ / x₂ - x₁

using two coordinates (3, 1)(0, 3)

where

x₁ = 3

x₂ = 0

y₁ = 1

y₂ = 3

Therefore,

slope = 3 - 1 / 0 - 3

slope = 2 / -3

slope = - 2  /3

Therefore, the slope of the line is - 2 / 3.

The volume of the region E is zero.

Using cylindrical coordinates, we can express the given surfaces as:

Paraboloid: ρ² - z = 24

Cone: z = 2ρ²

To find the volume of the region E enclosed between these surfaces, we need to determine the limits of integration in the cylindrical coordinate system.

The paraboloid and cone intersect when their corresponding equations are satisfied simultaneously. Substituting the equation of the cone into the paraboloid equation, we get:

ρ² - (2ρ²) = 24

-ρ² = 24

ρ² = -24

Since ρ² cannot be negative, this implies that there is no intersection between the paraboloid and the cone. Therefore, the region E does not exist, and the volume is zero.

An ordered pair is a solution of an equation in two variables if replacing the variables by the coordinates of the ordered pair results in a true statement.

In mathematics, an equation in two variables represents a relationship between two quantities. An ordered pair consists of two values, typically denoted as (x, y), that represent the coordinates of a point in a two-dimensional plane.

When these values are substituted into the equation, if the equation holds true, then the ordered pair is considered a solution or a solution set to the equation. This means that the relationship described by the equation is satisfied by the values of the ordered pair. In other words, the equation is true when evaluated with the values of the ordered pair.

Step-by-step explanation:

The equation y=1 represents a line Perpendicular to x=0.

The equation x=0 represents a vertical line passing through the point (0,0) on the x-axis. A line perpendicular to this line will be a horizontal line passing through the point (0, c) where c is a constant.

So, the equation of the line perpendicular to x=0 is y = c, where c is any constant.

Among the given options, the equation that represents a horizontal line is:

The greatest common factor of -18x^4y - 9xy^3 + 3xy^2 is 3xy. So, correct option is B.

To find the greatest common factor (GCF) of -18x4y, -9xy^3, and 3xy^2, we can factor out the common variables and their corresponding exponents.

First, we can factor out -3xy from each term, as it is a common factor:

-18x^4y - 9xy^3 + 3xy^2 = 3xy(-6x^3 - 3y^2 + y)

Now, we can simplify the expression by factoring the polynomial -6x^3 - 3y^2 + y further. We can see that 3 is a common factor of all the terms in the polynomial, so we can factor out a 3:

-6x^3 - 3y^2 + y = 3(-2x^3 - y^2 + 1/3 y)

Now, we can see that the GCF of the original terms is 3xy times the expression in the parentheses, which is -2x^3 - y^2 + 1/3 y.

Therefore, correct option is B.

Answer:

3xy

Step-by-step explanation:

First, we need to factor out the greatest common factor from the given terms.

The terms have an x, a y, and a 3 in common.

So, we can factor out 3xy from each term:

−18x4y − 9xy3 + 3xy2 = 3xy(-6x3 - 3y2 + y)

Now, we can see that there are no other factors that can be removed from the expression.

Therefore, the greatest common factor of −18x4y − 9xy3 + 3xy2 is 3xy.

So, the correct answer is 3xy.

Pythagoras says RS = √(5²+3²) = √34 ≈ 5.831

Answer:

RS ≈ 5.83 units

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

Here RS is the hypotenuse and the legs have measure 5 and 3, thus

RS² = 5² + 3² = 25 + 9 = 34 ( take the square root of both sides )

RS = \(\sqrt{34}\) ≈ 5.83 ( to 3 significant figures )
