Answer:
∠a = 133°∠b = 15°∠c = 75°∠d = 58°Step-by-step explanation:
We don't know the definitions, properties, postulates, or theorems on your list, so we'll use the following:
a right angle measures 90°a straight angle measures 180°the acute angles in a right triangle total 90°an exterior angle of a triangle is equal to the sum of the remote interior anglesthe measure of an angle is equal to the sum of the measures of its parts.__
∠a = 180° -47° = 133°; reasons 2, 5. The angles form a straight angle.
∠b = 47° -32° = 15°; reason 4
∠c = 90° - ∠b = 90° -15° = 75°; reason 3
∠d = 90° -32° = 58°; reasons 1, 5. The angles form a right angle. If you want to get picky, we know it is a right angle by reasons 1 and 2. The marked right angle and the sum of 32° and ∠d together form a straight angle.

Ryan is driving on a long road trip. He currently has 13 gallons of gas in his car. Each hour that he drives, his car uses up 1.25 gallons of gas. How much gas would be in the tank after driving for 4 hours? How much gas would be left after t hours?
Answers
Answer: gas left after 4 hours :8
Gas left after t hours: 13-1.25t
Step-by-step explanation:
The gas left after 4 hours will be 8 gallons and expression for the gas left after t hours will be 13 - 1.25 t.
It is given that Ryan has 13 gallons of gas in his car and car uses 1.25 gallons of gas per hour.
We have to find out the amount of gas left after 4 hours and expression for the gas left after t hours.
What do you mean by algebraic expressions ?
The algebraic expressions are those which are made up of variables, constants and algebraic operations i.e., addition, subtraction, etc.
As per the question ;
Ryan has 13 gallons of gas in his car.
The gas used per hour = 1.25 gallons
The gas used by car in 4 hours will be ;
= 1.25 × 4
= 5 gallons
So ,
The gas left after 4 hours will be equal to ;
= 13 - 5
= 8 gallons
Also ;
The gas left after t hours can be represented by equation ;
= 13 - 1.25 t
Thus , the gas left after 4 hours will be 8 gallons and expression for the gas left after t hours will be 13 - 1.25 t.

Symmetric property of equality to show that 3a = 4b, then 4b = 3a?
What is symmetric property of equality?The symmetric property of equality is a simple property that says we can interchange the sides of an equation without changing the truth-value of the equation. That is, if a = b, then b = a. Each side of the equation can be thought of as the mirror image of the other
We have the following information available from the question is:
We have to determine the which property can be used to show that if 3a = 4b, then 4b = 3a
Now, According to the question:
3a = 4b
4b = 3a (both are equal)
This property is used to simplify the equations, to reverse the equations, and also for proofs in numerical and non-numerical logic.

In a class of 28 students, 12 students packed their lunch.
We can write this as:
28 students = 12 students packed lunch ______(1)
We have to make 28 students into 336 students.
This can be done by multiplying 12 on both sides of the equation (1)
Multiply 12 on both sides.
12 x 28 students = 12 x 12 students packed lunch

A jar has 20 marbles: 3 green, 12 blue, 5 red.
What is the probability of randomly choosing a green marble after you have chosen red?
Answers
Answer:
0,40789
Step-by-step explanation:
To pick 1 red marble (from 5 red) from all 20 marbles is 5/20 = 0.25
To pick 1 green marble (from 3 green) from 19 because we already took red marble is 3/19 = 0.15789
The probability of randomly choosing a green marble after you have chosen red is 3/68.
Given
A jar has 20 marbles: 3 green, 12 blue, 5 red.
Probability;In probability theory, an event is a set of outcomes of an experiment or a subset of the sample space.
The total number of marbles = 20
The number of green marbles= 3
The number of blue marbles = 12
The number of red marbles = 5
The probability of choosing a red marble = Number of red marbles / Total number of marbles
= 5/20
The probability of choosing a green marble is = Number of green marbles / New total number of marbles
= 3/19
Therefore,
The probability of randomly choosing a green marble after you have chosen red is;
[tex]\rm=\dfrac{5}{20}\times \dfrac{3}{19}\\\\=\dfrac{1}{4}}\times \dfrac{3}{19}\\\\ = \dfrac{3}{68}[/tex]
Hence, the probability of randomly choosing a green marble after you have chosen red is 3/68.

If we have a polynomial in x with x as a factor, we know that there will be no constant term. This arises because every term will be a multiple of x, and thus there will be know constant term.
Because there is a constant term in our polynomial, namely 1, x is not a factor of [tex]2x^3-x^2-2x+1[/tex], as desired.
