ΔPQR has angle measurements of 80°, 50°, and 50°. What kind of triangle is ΔPQR?

Answers

Answer:

Isosceles Triangle; Acute Triangle

Step-by-step explanation:

Review your definitions of the different types of triangles:

acute triangle- a triangle that has three acute (less than 90 degrees) angles

obtuse triangle- a triangle that has an obtuse (greater than 90 degrees) angle.

right triangle- a triangle that had one right (90 degrees) angles

isosceles triangle- a triangle with two congruent sides and one unique side and angle.

equilateral triangle- a triangle with three congruent sides and three congruent angles.

scalene triangle- a triangle with no congruent sides and no congruent angles.

With these definitions, we can classify ΔPQR as an isosceles acute triangle.

why do you use denominator of 100 when you write a percent as a fraction?

Answers

Answer:

A percentage or percent for short is a fraction; a fraction that always has the denominator as 100. Because the denominator of a percent is always a 100, no matter what the numerator is, we replace 100 with the percent symbol % after the number.

What is the result when 3/8x + 2 1/5 is subtracted from 3 1/2x - 4 1/10?

Don’t put a link.

Answers

Answer:

Option 3 3 1/8x - 6 3/10

Step-by-step explanation:

(3 1/2x - 4 1/10) - (3/8x + 2 1/5)

Divide it into parts:

(3 1/2x - 3/8x) + (-4 1/10 - 2 1/5)

3 1/2x - 3/8x = 3 4/8x - 3/8x = 3 1/8x

-4 1/10 - 2 1/5 = -4 1/10 - 2 2/10 = -6 3/10

So we get:

2 1/4x - 6 3/10

trying to cheat on a performance matter test but the answer is the last one -3 1/8 x + 6 3/10

Define two terms, each containing the variables x and y, with exponents on each. (For example: 10x3y−5.) Find the quotient of the two terms. Explain step by step how you found the quotient.

Answers

Answer:Two such terms are 7x^3*y^9 and -3x*y^5

Their quotient is

7x^3*y^9

--------------

-3x*y^5

This can be simplified as follows:

The numerical coefficients become -7/3.

x^3/x = x^3*x^1 = x^(3 - 1) = x^2 (we subtract the exponent of x in the denominator from the exponent of x in the numerator).

Next, y^9*y^5 = y^4.

The quotient in final reduced form is then (-7/3)x^2*y^4

People make a variety of mistakes when making decisions. These mistakes are generally associated with a host of biases that occur when we use subconscious judgmental shortcuts to reduce information processing demands. These shortcuts can be useful in evaluating current problems because they are representative of knowledge we have gained in the past. However, they can also lead to systematic errors that erode the quality of our decisions. This activity is important because understanding decision-making biases can help you to make more rational decisions and avoid using biases in the wrong situations. The goal of this activity is to help you identify and differentiate between the most common decision-making biases.Professor French tells you that South Africas stock market undervalued and suggests that it is a good investment.
