Why are some right triangles considered special?

Answers

Answer 1
Special right triangles. A special right triangle is a right triangle with some regular feature that makes calculations on the triangle easier, or for which simple formulas exist. For example, a right triangle may have angles that form a simple ratio, such as 45-45-90. This is called an "angle based" right triangle.

circumference in terms of pi does anyone know this?

Answers

Answer:

15 pi

Step-by-step explanation:

Answer:

15π cm

Step-by-step explanation:

The circumference of a circle can be found using the following formula:

c= d* π

We know that the diameter of the circle is 15 centimeters. Therefore, we can substitute 15 cm in for d

c= 15 cm * π

Since we are told to find the circumference in terms of pi, the answer is left as:

c= 15*π  cm

c= 15π cm

One student says -5 is bigger than -4 and uses money as the analogy: “If I owe $5, I have a bigger debt than if I owe $4.” What is wrong with this argument?

Answers

Answer:

This is a bad argument because when talking about negative numbers, the closer the numbers are to 0, the bigger they are. -4 is closer to 0 than -5, so -4 is the bigger number.

Step-by-step explanation:

Answer:

-5 is not larger than -4.

Step-by-step explanation:

Think of a number line. The absolute value of -5 is 5, meaning -5 is 5 away from 0 to the left. On the other hand, -4's absolute value is 4, meaning -4 is 4 away from 0 to the left. In the money scenario, owing $5 is a bigger debt because the absolute value is larger, not the number itself. Hope this helps!!

subtract (-3y2 − 8) − (-5y2 + 1)

Answers

Answer:

2 y^2 - 9

Step-by-step explanation:

(-3y^2 − 8) − (-5y^2 + 1)

Distribute the negative sign

(-3y^2 − 8) + 5y^2 - 1

Combine like terms

-3y^2 + 5y^2 - 1 − 8

2 y^2 - 9

Answer:

The answer to (-3y² - 8) - (-5y² + 1) is 2y² - 9

Step-by-step explanation:

[tex](-3y^2-8)-(-5y^2+1)[/tex]

Since there is a minus sign in front of the second parentheses, then the terms within that parentheses will be changed to their opposite signs.

[tex]-3y^2-8+5y^2-1[/tex]

Step-by-step explanation:

Answer:

x + 90 + 63 = 180

Step-by-step explanation:

We do not have the value for angle B so we have to assume that B plus the 45 is 90. using this info we can see that A + 90 + 63 is equal to the line, which is 180(as all lines are). We can then get the equation x + 90 + 63 = 180

Events A and B are overlapping.

P(A) = 4/11; P(B) = 3/11, P(A and B) =2/11 .

Find P(A or B).

Answers

Answer:

5/11

Step-by-step explanation:

Since the events are overlapping...

P(A or B) = P(A) + P(B) - P(A and B)

P(A) = 4/11

P(B) = 3/11

P(A and B) = 2/11

P(A or B)  = 4/11 + 3/11 - 2/11

P(A or B)  = 5/11
