What is the area of a right angled triangle having base 10 cm and height 5 cm?
The area of a triangle with the base of 10 cm and the height of 5 cm is 25 square cm.
In the given question we have to find the area of a triangle with the base of 10 cm and the height of 5 cm.
The entire area bounded by a triangle's three sides is referred to as the triangle's area. In essence, it equals half of the base times height, or A = 1/2bh. So, in order to calculate the area of a triangular polygon, we need to know its base (b) and height (h).
Area of Triangle = 1/2 ×b×h
Area of Triangle = 1/2 ×10×5
Area of Triangle = 5×5
Area of Triangle = 25 square cm
Hence, the area of a triangle with the base of 10 cm and the height of 5 cm is 25 square cm.

If grapes are $1.99/pound and you buy 2.25 pounds of grapes, how much change will you receive if you hand the cashier a $5 bill
Using simple mathematical operations, we know that we will get a change of $0.5.
What are mathematical operations?An operation is a function in math that transforms zero or more input values into a strictly delineated output value.
The operation's arity is influenced by the number of operands.
For all real numbers, the four fundamental arithmetic operations in mathematics are: Finding the sum in addition ('+') Subtraction (Difference-finding; "-" Multiplication (Identifying the result; "×" Finding the quotient in division ("÷)
So, we know that:
Grapes cost $1.99.
We purchased 2.25 pounds of grapes.
The change we will receive if we gave a $5 bill will be:
5 - (1.99*2.25)
5 - 4.4775
0.5225
Rounding off: $0.5
Therefore, using simple mathematical operations, we know that we will get a change of $0.5.

What are the 3 exponent properties?
The 3 main exponent properties are:
The product of powers property: (a^m) * (a^n) = a^(m+n)The quotient of powers property: (a^m) / (a^n) = a^(m-n)The power of a power property: (a^m)^n = a^(m*n)The product of powers property states that when you multiply two numbers with the same base, you can add the exponents to find the result. For example, (2^3) * (2^4) = 2^(3+4) = 2^7
The quotient of powers property states that when you divide two numbers with the same base, you can subtract the exponents to find the result. For example, (2^5) / (2^3) = 2^(5-3) = 2^2
The power of a power property states that when you raise a power to another power, you can multiply the exponents to find the result. For example, (2^3)^2 = 2^(3*2) = 2^6
These three properties help simplify algebraic expressions that include exponents and make it easier to solve equations and perform other mathematical operations.

The drama club is selling tickets to their play to raise money for the show's expenses. Each student ticket sells for $6.50 and each adult ticket sells for $11. The auditorium can hold a maximum of 130 people. The drama club must make a minimum of $1100 from ticket sales to cover the show's costs. Also, they can sell at least 90 adult tickets. If x x represents the number of student tickets sold and y y represents the number of adult tickets sold, write and solve a system of inequalities graphically and determine one possible solution.
The graph for the inequality is attached below.
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Given:
Each student ticket sells for $6.50 and each adult ticket sells for $11.
let the number of student ticket sold be x and number of adult ticket sold be y.
so, the inequality is
x + y < 130
and, 6.5x + 11y >1100.
Solving the inequality we get
x= 73.33 and y = 56.667
Now, if they sell at least 90 adult tickets then they sell at most 40 children ticket.
Hence, the solution is (73.33, 56.667).

it multiply with 3
then
3×(9x+2y=7)

What is the first step to solving quadratic equations in factored form?
Transform the equation using standard form in which one side is zero is the first step to solving quadratic equations in factored form.
What is quadratic equations in factored form?Form factored (of a quadratic expression) A quadratic expression is said to be in factored form if it can be represented as the sum of a constant and two linear factors. If and only if its discriminant is a perfect square, a quadratic equation with integer coefficients can be factored over integers. To begin factorising an expression, "take away" any shared factors that the terms have. As x appears in both terms, if you were asked to factor x2 + x, you would write x(x + 1). It is common to refer to a polynomial as "irreducible" if it cannot be factored. It might not be factorable if the coefficients lack common components or are not reasonable.Use standard form to transform the equation so that one side is zero.Factor the non-zero side, step 2.3. Reset each component to zero (Remember: a product of factors is zero if and only if one or more of the factors is zero).Solve each of the ensuing equations.To learn more about quadratic equations refer to:

What are exponents for Grade 7?
Exponents are a way to represent the repeated multiplication of a number by itself. The exponent is written as a small number raised to the right of the base number.
For example, in the expression 2^3, 2 is the base and 3 is the exponent. This means 2 multiplied by itself 3 times, equal to 2 x 2 x 2 = 8. The exponent tells how many times the base is multiplied by itself.
In grade 7, students typically learn the basic rules of exponents such as how to multiply and divide numbers with the same base, and how to raise a power to a power. They also learn about scientific notation, which is a way of writing very large or tiny numbers using exponents.

The solution to the system of equations y = -3x - 2 and 5x + 2y = 15 is (-19, 55).
A system of linear equations is a set of two or more equations which includes common variables. The solution to a system of equations, is the value of the unknown variables used in the equations that satisfies both equations.
Given two linear equations in x and y,
y = -3x - 2 (equation 1)
5x + 2y = 15 (equation 2)
Use substitution method to find its solution. Since the first equation is already expressed as y in terms of x, substitute the first equation to the second equation.
5x + 2y = 15 (equation 2)
5x + 2(-3x - 2) = 15
5x - 6x - 4 = 15
Combining all terms containing the variable x on one side and the constants on the other side of the equality, and solve for x.
5x - 6x - 4 = 15
-x = 15 + 4
x = -19
Substitute the value of x in the first equation and solve for y.
y = -3x - 2 (equation 1)
y = -3(-19) - 2
y = 55
