Aaron works at a garden center where he plants
flowers. It takes him 3 1/2 hours to plant 21 flowers.
How many plants can he plant in 1 hour?

Ellie needs 5050 grams extra fertilizer and total cost of fertilizer = 22.81-pound sterling.

Multiplication is the product of two or more numerical terms. Division is the process of dividing any numbers into equal parts.

Cost of 750 grams fertilizer = 2.95-pound sterling,

the area of the lawn = 145 square meters.

Ellie uses 40 grams fertilizer for every square meter of lawn.

So, fertilizer needed for the 145 square meters of land = (145 × 40)

                                                                                        = 5800 grams

it stated earlier that 750-gram fertilizer was bought but Ellie needs 5800 grams fertilizer.

the extra amount of fertilizer that Ellie needs = (5800 - 750) = 5050 grams.

cost of 750 gram fertilizer = 2.95-pound sterling

cost of 5050-gram fertilizer = (2.95 × 5050) / 750 = 19.86-pound sterling

cost of extra fertilizer = 19.86-pound sterling.

Total cost of fertilizer = (2.95 + 19.86) pound sterling

                                   = 22.81-pound sterling

Answer: -9 1/4

Step-by-step explanation:

The domain of the given function f(x) = (x + 4)/x² + x - 12 is given by {x|x ≠ 3, 4}.

In Mathematics, a domain simply refers to the set of all real numbers for which a particular function is defined. In Mathematics, the horizontal extent of a graph represents all domain values (input values) and they are read and written from smaller to larger numerical values, and from the left of a graph to the right.

By critically observing the graph of this function f(x) = (x + 4)/x² + x - 12 shown in the image attached below, we can reasonably and logically deduce the following domain and range:

Domain = (-∞, 4) U (-4, 3) U (3, ∞); {x|x ≠ 3, 4}.

Range = (-∞, -1/7) U (-1/7, 0) U (0, ∞); {y|y ≠ 0, -1/7}.

Addition, subtraction, multiplication, division, reflexive, symmetric, transitive, substitution, and square root qualities are the main nine properties of equality.

The nine basic characteristics of equality are addition, subtraction, multiplication, division, reflexive, symmetric, transitive, substitution, and square root. Real number-based algebraic problems can be resolved with the aid of the addition, subtraction, multiplication, and division properties of equality.

When you add the same amount to both sides of an equation that has two equal expressions, the equation will stay equal. Finding the value of the variable that makes an equation true is the process of solving an equation.

The Subtraction Property of Equality asserts that when an equal value is subtracted from or removed from two equal objects, a new equal quantity is created. A mathematical statement with two equivalent sides is denoted by an equal sign. The formula for the subtraction property is if a = b, then a - c = b - c.

The solutions to sin(θ) = -√3/2 in the interval 0 ≤ θ ≤ 2π are approximately θ = 5π/3 and θ = 4π/3.

What is an interval?

An interval in math is measured in terms of numbers. An interval includes all the numbers that come between two particular numbers. This range includes all the real numbers between those two numbers.

The equation sin(θ) = -√3/2 has two solutions in the interval 0 ≤ θ ≤ 2π.

Since the sine function has a range [-1, 1], the value of -√3/2 lies in the range of the sine function, so there are solutions in the specified interval.

Using the unit circle, we can find the values of θ that satisfy the equation. In the unit circle, the sine of an angle is equal to the y-coordinate of the point on the circle that corresponds to that angle.

The point (-√3/2, -1/2) lies on the unit circle and has an angle θ that satisfies the equation.

The other solution can be found by adding π to θ, since the sine function has a period 2π.

Hence, the solutions to sin(θ) = -√3/2 in the interval 0 ≤ θ ≤ 2π are approximately θ = 5π/3 and θ = 4π/3.

What is the midpoint of the line segment?

The midpoint of a line segment is the point that is exactly in the middle of the line segment. It is the point that divides the line segment into two equal parts.

To find the midpoint of a line segment, you can use the formula:

Midpoint = ( (x1 + x2) / 2 , (y1 + y2) / 2 )

Where x1, y1 and x2, y2 are the coordinates of the two endpoints of the line segment.

In this case, the endpoints of the line segment are B(2, 1) and C(–8, –4).

So we can substitute the coordinates of B and C in the midpoint formula:

Midpoint = ( (2 + -8) / 2 , (1 + -4) / 2 )

Midpoint = ( -3 , -1.5)

The midpoint of the line segment is (-3, -1.5).

Hence, point M has the coordinates (-3, -1.5) which are written as decimals.

Step-by-step explanation:

Having two sets of parallel sides, a parallelogram is a quadrilateral. Because squares must have two sets of parallel sides, they are all parallelograms.

An object with four sides is a quadrilateral. The quadrilateral with two pairs of parallel sides is known as a parallelogram. A parallelogram essentially appears as follows:

Contrary Sides

Starting with the opposite sides theorem, which asserts that a parallelogram's opposite sides are equal, let's go on.

Take the parallelogram ABCD as an example, where side AB is parallel to side CD and side AD is parallel to side BC.

In order to connect points A and C, let's now draw a line. The parallel lines AB and C are transposed by this line.

The triangles ABC and CDA were formed by line AC, as can be seen.

Interior angle 1 equals interior angle 2, and interior angle 3 equals angle 4 in these two triangles, proving the alternate interior angles theorem of parallel lines.

Asymmetrical Angles

In a parallelogram, the opposing angles are also equal. Let's move on to that. Take into account the parallelogram ABCD that is the same but has a transversal line. The different interior angles are equal in this instance, as can be seen.

Angle 1 equals Angle 2, and Angle 3 equals Angle 4. Angle 1 plus Angle 3 equals Angle 2 plus Angle 4, therefore the inverse is the sum of the opposite. It would also demonstrate that the other angles are equal if another transversal were drawn between points B and D. So:

The parallelogram's opposite angles are equal.

We can see that a parallelogram has equal opposite angles.

Next-to-Next Angles

The following angles are now up for discussion. The consecutive angles theorem states that a parallelogram's total consecutive angles are 180°.

99.4% chance that you are healthy if you receive a negative test. 67.9% chance that you are sick if you receive a positive test.

14% of population would test positive for the disease

Step 1. Give algebraic names to various events described:

Step-2: Model the given situation mathematically.

In other words, the conditional probability of the event that the diagnostic test gives a negative result (not A), given that the tested person does not have the disease (E2 = not E1) is given to be 90%

Thus P(not A/E2)=90%

Further, it is given that five percent of the population has the disease. In other words, the event that a person has the disease (E1) has the probability of 5% Thus P(E1)=5%

It is needed to find what percent of that population would test positive for the disease.

Thus, the probability that a person will have a positive result when tested, P(A) is to be determined.

We can start by using algebra to represent the information given in the problem. Let T be the temperature at midnight.

What is the short definition of temperature?

Temperature is a physical property of matter that measures the degree of hotness or coldness of an object or substance. It is a measure of the average thermal energy of the particles in a substance, and it can be measured in various units such as Celsius, Fahrenheit, and Kelvin.

According to the problem, the temperature at the current time is -7 degrees. We know that the temperature tripled since midnight, so we can write an expression for the current temperature as:

T * 3 = -7

We know that the temperature also rose by 5 degrees since midnight, so we can add 5 to the above expression:

T * 3 + 5 = -7

Now to find out the temperature at midnight, we need to solve for T, which is the temperature at midnight.

We can solve for T by isolating it on one side of the equation. To do this, we can start by subtracting 5 from both sides:

T * 3 = -12

Next, we divide both sides by 3:

T = -4

So the temperature at midnight was -4 degrees. T = -4
