polynomials multiple choice math question ?
pls help
Answer:
The answer is D. Variable. The "letters after the numbers" are always variables. A coefficient is the number that the variable is being multiplied by. An exponent would be something like this: [tex]x^{2} \\[/tex] with the 2 being the exponent. A binomial is an algebraic expression of the sum or the difference of two terms.

Answer:
10 donuts for $11.50
Step-by-step explanation:
11.50 divided by 10 = 1.15
That means that for this deal, each donut costs $1.15
15 divided by 12 = 1.25
That means that each donut costs $1.25
$1.15 is less than $1.25, so the answer is 10 donuts for $11.50

Step-by-step explanation:
A ladder is inclined at only 23 degrees against the wall what the height of the ladder reaches up the wall
Step-by-step explanation:
To determine what the height of the ladder reaches up the wall we need to know the height of ladder which is not provided in the question.
So if I assume the height of ladder to be 10ft( just a general assumption)
Then, inclined ladder, wall and distance been the bottom of the ladder and wall will form a right angle triangle.
where height of ladder will be hypotenuse, height of the ladder reaches up the wall will be perpendicular and distance been the bottom of the ladder and wall will be base.
Since, A ladder is inclined at 23 degrees against the wall
⇒ height of the ladder reaches up the wall = Height of ladder×sin23°
= 10ft × sin23° = 3.9073 ft

On a flight from San Diego to Baltimore, 18 of the 156 seats are empty. What is the ratio of filled seats to empty seats on the flight?
Answer:
138/18
23:3
Step-by-step explanation:
There are 18 empty seats so we can already fill out the right side of our ratio (yes I said our. Oh the communism!) with 18, to make :18.
We also know that there are 156 seats, so we will subtract 18 to find the amount of the filled seats, which is 156-18 = 138
138 seats are filled.
We can put the 138 on the left side of the ratio which is now
138:18
We now divide both sides by 2 to try to get the simplified form.
138/2 = 69
18/2 = 9
69:9
Now we divide both sides by 3.
69/3 = 23
9/3 = 3
23:3
23 and 3 are both prime numbers meaning that there are no factors to divide or simplify with anymore except for the same number and 1.
The answer is 23:3

Answer:
It's D
Step-by-step explanation:
First:
Convert any mixed numbers to fractions.
Then your initial equation becomes:
25/2 ÷ 3/4
Applying the fractions formula for division,
= 25 x 4
2 x 3
=100/6
Simplifying 100/6, the answer is
= 16 2/3

2x - 3 = - x + 9
Help me
Answer:
x = 4
Step-by-step explanation:
here's your solution
=> 2x - 3 = - x + 9
=>. 2x + x = 9 + 3
=> 3x = 12
=>. x= 12/3
=>. x= 4
hope it helps
Answer: x=4
Step-by-step explanation:
How to solve x:
First you would collect like terms. Like terms are terms that have the same variable and powers. So, you would add x to both sides so it would be 3x-3=9 then you would add 3 to both sides so it would be 3x=12 then after that you would divide that by 3 which gives you x=4.
So x would be 4.
Side notes:
You do the inverse of what it tells you to “undo” the equation.

Question 1: Find the sum of the measures of the interior angles of a heptagon.
Question 2: The sum of the measures of the interior angles of a convex polygon is 3060°. Classify the polygon by the number of sides.
Question 3: Find the measure of each interior and exterior angle of a regular 30-gon.
Answer:
Sum of interior angles of a regular polygon:
S = (n - 2)*180°Question 1:Heptagon has 7 sides
Sum of interior angles:
S = (7 - 2)*180° = 5*180° = 900°Question 2:S = 3060°, n = ?
(n - 2)*180° = 3060°n - 2 = 3060°/180°n - 2 = 17n = 1919-sided polygon (Enneadecagon)
Question 3:Let each angle be x

Write an inequality to represent the situation: A theater rents their space for $250 per night. If the company charges $8 per ticket, then what is the least number of tickets that must be sold in order to make a profit? PLEASE HELP! This is due tomorrow!
Answer: 32 tickets
Step-by-step explanation:
Since the theater rents their space for $250 per night and the company charges $8 per ticket, the least number of tickets that must be sold in order to make a profit will be:
= ($250/8)
= 31 1/4
The number gotten above is the number that'll bring about an Equilibrium. To make a profit the company must sell at least 32 tickets

The lengths of the sides of a triangle are given below. Classify the triangle as acute, obtuse, or right.
7, 9, 3
A. Acute Triangle
B. Obtuse Triangle
C. Right Triangle
Answer:
B. Obtuse TriangleStep-by-step explanation:
Use Pythagorean to identify if the triangle is right:
9² = 7² + 3²81 = 58We see the triangle is not right and the difference of the squares tells us the angle opposite to side with measure of 9 is greater than 90°.
It means the triangle is obtuse.
Correct choice is B
