Answer:

Isabella can buy together 5 paintbrushes ( p ) and jars of paint ( p ) : j + p = 5, She can`t buy 4 items ( because 4 * $0.99 = $3.96 < $4.87 ) and she also can`t buy 6 items ( 6 * $0.95 = $5.70 > $4.87 ). So: p = 5 - j. Another equation is: 0.95 * ( 5 - j ) + 0.99 j = 4.87, 4.75 - 0.95 j + 0.99 j = 4.87; 0.04 j = 0.12; j = 0.12 : 0.04; j = 3, p = 5 - 3 = 2. We can prove it: 0.95 * 2 + 0.99 * 3 = 1.90 + 2.97 = 4.87. Answer: Isabella buys 2 paintbrushes and 3 jars of paint.

[tex]-3 \frac{1}{3}t+6[/tex]

Step-by-step explanation:

Given expression:

[tex]\sf 7\frac{1}{3}t-\left(10 \frac{2}{3}t-6\right)[/tex]

Remove the parentheses:

[tex]\implies \sf 7\frac{1}{3}t-10 \frac{2}{3}t+6[/tex]

Factor out the common term t:

[tex]\implies \sf \left(7\frac{1}{3}-10 \frac{2}{3}\right)t+6[/tex]

Change the mixed numbers into improper fractions:

[tex]\implies \sf \left(\dfrac{7 \cdot 3+1}{3}-\dfrac{10 \cdot 3+2}{3}\right)t+6[/tex]

[tex]\implies \sf \left(\dfrac{22}{3}-\dfrac{32}{3}\right)t+6[/tex]

Subtract the fractions:

[tex]\implies \sf \left(\dfrac{22-32}{3}\right)t+6[/tex]

[tex]\implies \sf \left(\dfrac{-10}{3}\right)t+6[/tex]

Convert the improper fraction back into a mixed number:

[tex]\implies -3 \frac{1}{3}t+6[/tex]

A chemical element's atom is a particular type of particle of substance. A positively charged electron or many negatively charged electrons encircle the central nucleus of an atom.

Electrons: If an electron leaves an atom, it is said to be ionized. Ionization can occur through various processes, such as collision with another particle or exposure to electromagnetic radiation.

Protons: Protons are found in the nucleus of an atom, and are held in place by the strong nuclear force. If a proton were to leave the nucleus, it would no longer be a stable atom and it would become an ion.

Neutrons: Neutrons are also found in the nucleus of an atom and are held in place by the strong nuclear force. If a neutron were to leave the nucleus, it would no longer be a stable atom, and it would become a different element.

An inequality is a mathematically explicable relationship between two expressions that can be represented by any of the following symbols: >, <, ≤, ≥, and ≠.

A mathematical statement known as an inequality uses the inequality symbol to represent the connection between two expressions. The terms on each side are not equal when there is an inequality sign present.

It suggests that the left and right expressions should be greater or smaller than one another, or the opposite. Literal inequalities are ones where the inequality symbols indicate the connection between two algebraic expressions.

A virus spreading around Brookfield will infect 988 people in the next 3 days.

What is an equation?

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("=").

Number of people infected by the virus = 685

The rate at which the virus is infecting = 13%

The virus is spreading at 13% rate each day.

To deduce the number of people who will get infected in next 3 days.

The final equation will be -

= 685 × ( 1 + 13%)³

= 685 × (113/100)³

= 685 × (1.13)³

= 685 × 1.442

= 987.77 ≈ 988

Therefore, the number of people who will get infected is 988.

What is a linear equation ?

A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form

Ax + B = 0

e.g. x-10=0. Here, x is a variable, A is a coefficient and B is constant.

The standard form of a linear equation in two variables is of the form

Ax + By = C

e.g. 2x-4y=10. Here, x and y are variables, A and B are coefficients and C is a constant.

Now,

Since, AB and BC are not perpendicular,

No, Points A(-2,1), B(4,7), and C(1,4) cannot be three vertices of rectangle ABCD.

The correct option is A.

A rectangle is a quadrilateral in which all the angles are equal and the opposite sides are equal and parallel.

A rectangle is a closed two-dimensional figure with four sides, all the angles of a rectangle are equal to 90°.

Given points

A(-2,1),

B(4,7), and

C(1,4)

For being vertices of rectangle

Angle between line segment AB and BC should be 90°.

Slope of line AB

m = (y - y')/(x-x')

m = (7 - 1)/(4 - -2)

m = 6/6

m = 1

Slope of line BC

m' = (y - y")/(x - x")

m' = (7 - 4)/(4-1)

m' = 3/3 = 1

Since slope of the two lines is same that is both are parallel, which is only possible when A, B, C are in a straight line.

Since the function g is given in three equivalent forms, a form which most quickly reveals the vertex is: C. g(x) = 3(x + 1)² - 12.

The vertex is equal to (-1, -12).

In this exercise, you are required to determine and select the vertex form of a function g that is written in three equivalent forms. Mathematically, the vertex form of a quadratic equation is given by this formula:

y = a(x - h)² + k

Where:

Based on the information provided, we can reasonably infer and logically deduce that a mathematical expression which quickly reveals the vertex of the quadratic equation is given by g(x) = 3(x + 1)² - 12.

Since the directrix is horizontal, the axis of symmetry would be vertical. Additionally, the distance (a) from directrix to vertex on the axis of symmetry is equal to 3.

Decide on the input values. Choose the output values. You should classify a connection as a function if each input value results in only one output value.

Any possible input value will result in exactly one output value, which is the definition of a function. "The output is a function of the input" is how we phrase it. The range is comprised of the output values, whereas the domain is made up of the input values. But not all relations are functions, and vice versa.

Formulas or graphs are typically used to depict functions.There are many different kinds of relations and functions, including empty relations, universal relations, reflexive relations, symmetric relations, transitive relations, equivalence relations, constant functions, polynomial functions, identity functions, on-to-one functions, onto functions, bijective functions, etc.

No relationship has the characteristics of a function if each input does not have a distinct output.There are nine different forms of mathematical relations: empty relation, full relation, reflexive relation, irreflexive relation, symmetric relation, anti-symmetric relation, transitive relation, equivalence relation, and asymmetric relation.

To find the length of a line segment given the coordinates of the midpoint and one endpoint, you can use the distance formula. The distance formula is:

d = √((x2 - x1)^2 + (y2 - y1)^2)

Where (x1, y1) and (x2, y2) are the coordinates of two points, and d is the distance between the points.

Given the midpoint (mx, my) and one endpoint (ex, ey) you can use the following steps to find the length of the segment:

For example, if the midpoint of a segment is (5,7) and one endpoint is (7,10), the length of the segment is:

d = √((7-5)^2 + (10-7)^2)

d = √((2)^2 + (3)^2)

d = √(4+9)

What is an expression?

An expression is a mathematical phrase that can contain numbers, variables, and operators. Expressions do not contain an equal sign and they can't be solved for a single value. They are used to represent a value or a set of values.

The given expression is     [tex]\frac{\sqrt[4]{16xy^4}}{x^{\frac{1}{2}}y^{\frac{1}{2}}}[/tex]

In order to write the expression in the form of [tex]ax^by^c[/tex], we need to simplify it.

First, we simplify the fourth root of [tex]16xy^4[/tex] by taking the fourth root of 16, which is 2. So, the expression becomes

[tex]2\frac{xy^4}{x^{\frac{1}{2}}y^{\frac{1}{2}}}[/tex]

Next, we simplify the fraction by canceling out the[tex]x^{\frac{1}{2}} $$ and $ y^{\frac{1}{2}}[/tex] from the numerator and denominator. This gives us [tex]2xy^3[/tex]

So the expression in the form of [tex]ax^by^c[/tex] is [tex]2xy^3[/tex], where a = 2, b=1, and c=3.

the product of a, b, and c is 2 * 1 * 3 = 6.

The 4 types of exponents are positive, negative, zero, and rational.

When an expression or statement of specific natural numbers (0 to ∞), is represented as repeated power by multiplication of its units, then the resulting number is an Exponent.

Two events are independent if the occurrence of one event does not affect the chances of the occurrence of the other event. The mathematical formulation of the independence of events A and B is the probability of the occurrence of both A and B being equal to the product of the probabilities of A and B (i.e., P(A and B)

For two events C and D. For the two events to be independent events then;

P(C│D) = P(C∩ D)/ P(D) = P(C)

P(C) = Probability of getting an even number

P(C│D) = P(C∩ D)/ P(D)

P(C∩ D)= 1/3 × 1/2 = 1/6
