Answer:
40
Step-by-step explanation:
The way you find the area is 1/2 *base*height
In this situation, it would be 1/2 *10*8
When we solve, a half of 10 is 5, and then we multiply 5*8
5*8=40

While introducing two-digit addition to a second-grade class, the teacher first models adding a problem with Unifix cubes to demonstrate the relationship between tens and ones. The next day, the teacher models adding a problem with base ten blocks and has the students draw and write the problem in their math notebooks. On day three, the teacher moves to a more abstract approach to adding two-digit numbers. What would be the next step for the teacher in this lesson series?
The next step for the teacher in this lesson series is to give them questions on addition to show the knowledge regarding the addition.
How to illustrate the addition?From the information, the teacher is introducing two-digit addition to a second-grade class.
In this case, the teacher first models adding a problem with unifix cubes to demonstrate the relationship between tens and ones and also models adding a problem with base ten blocks and has the students draw and write the problem in their math notebooks.
Therefore, it can be deduced that the teacher has taught them the necessary things to know regarding the topic. Hence, it's important to give them questions on addition to show the knowledge regarding the topic.

What are the solutions to the following system of equations?
2x − y = 6
y = x2 − 9
Answer:
(3, 0) and (-1, -8)
Step-by-step explanation:
Equation 1
2x - y = 6Rearrange it so that it is equal to 'y'-y = 6 - 2xy = 2x - 6Substituting the value of y in Equation 2
y = x² - 9⇒ 2x - 6 = x² - 9⇒ x² - 2x - 3 = 0⇒ x² + x - 3x - 3 = 0⇒ x(x + 1) - 3(x + 1) = 0⇒ (x - 3)(x + 1) = 0⇒ x = 3, -1Taking x = 3
y = 2(3) - 6y = 0Solution 1 = (3, 0)Taking x = -1
y = 2(-1) - 6y = -2 - 6y = -8Solution 2 = (-1, -8)Solutions

Explain for me functions in mathematics
Step-by-step explanation:
You can say that a function take input and outputs something back. for example, let's y = X + 3. You may think this is a equation.Yeah it is but it is also a function. The original function notation is for example f(X) = X+3.But we set y = f(X) so it turn out to be y=X+3.Basically these two have the same meaning.X is a input in the function above.If you set X= 5,the input is now 5 and you will get a kinda output of 5+3 =8.so y= 8 or f(5) = 8.That's all.You can check out more on the internet.
state the probability and odds for each event: think about rolling a die.
P(4) _____ _____
P(1 or 3) ______ ______
Answer: 1/18
Step-by-step explanation:
the probability that you roll a 4 on a standard die is 1/6 because there is 6 sides then the probability of rolling a 1 or a 3 is 2/6 or one third. then multiply 1/3 by 1/6 and you get the final answer of 1/18 :)

Select each function that has an inverse that is also a function for all values of x.
A. F(x) = 2x^2 + 4x - 3
B. F(x) = 2x + 3
C. F(x) = 3/2(x) + 2
D. F(x) = 2x^3 + 2
E. F(x) = 2x^4 + 3x^2 - x + 1
Considering the condition for an inverse function, it is found that the functions that also have an inverse for all values of x are given by:
B. F(x) = 2x + 3
C. F(x) = 3/2(x) + 2
D. F(x) = 2x^3 + 2
What is the condition for an inverse function?A function f(x) has an inverse if it does not have any horizontally aligned points, that is, if f(a) = f(b), then a = b.
Polynomial functions of even degrees have horizontally aligned points, hence functions A and E do not have inverses.
The other polynomial functions, with odd degrees, have inverses.

Luke is cutting a board to make a trapezoid for a project. What is the angle measure of the piece left over after Cut A?
The angle measure of the piece is the amount of space left between the vertices
The angle of the piece left over after cut A is 35 degrees
How to determine the angle measure of cut A?In cut A, we have the following expression
x + 55 = 90
Subtract 55 from both sides to determine the measure of angle left
x = 35
Hence, the angle of the piece left over after cut A is 35 degrees
