What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
Given square on the right is a scaled copy of the square on the left.
So 11 is being multiplied by something to get to 33/2
So 11x = 33/2
Solve for x:
11x = 33/2
x = 33/ 2(11)
x = 3/2
The scale factor as fraction in simplest form is 3/2.

Step-by-step explanation:
2x² - 5x + 3 = 0
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 2 × 3 = 6 and sum = - 5
The factors are - 2 and - 3
Use these factors to split the x- term
2x² - 2x - 3x + 3 ( factor the first/second and third/fourth terms )
2x(x - 1) - 3(x - 1) = 0 ← factor out (x - 1) from each term
(x - 1)(2x - 3) = 0
Equate each factor to zero and solve for x
x - 1 = 0 ⇒ x = 1
2x - 3 = 0 ⇒ 2x = 3 ⇒ x = [tex]\frac{3}{2}[/tex]

20. A. y= 10x = 15
21. C. Php 75.00
22. B. Php 195.00
Step-by-step explanation:
She has to pay 25 Pesos for one hour and only ten more each hour after that. That can be represented in the formula Y= 10x +15. To solve the rest of the questions, just substitute 6 hours for question 21 and 18 hours for question 22.
A, y= 10x + 15
C, 75.00
B, 195.00
Explanation for the first question:
We can see in the table the price is going up by 10
25 to 35 to 45, etc
So 10x + 15
Explanation for question 2:
We know the equation is 10x + 15. X is the amount of hours so that is our 6. If you plug it into the equation you get
10(6) + 15
Multiply first
60+15
Then add
You get 75.
Explanation for question 3:
Do the same as question 2 just with 18 instead of 6.

A car begins from rest and accelerates at a rate of +3.0 m/s^2 for 5.0 seconds.
a. Determine the car's final speed.
b. Calculate the car's average speed during its trip
Answers
Answer:
15m/s
Step-by-step explanation:
we know that
v = u + at
= 0+ 3*5
=15m/s
The final speed of a car is 15 m/s.
Given that, a car begins from rest and accelerates at a rate of +3.0 m/s^2 for 5.0 seconds.
What is the speed?The speed formula can be defined as the rate at which an object covers some distance. Speed can be measured as the distance travelled by a body in a given period of time. The SI unit of speed is m/s.
Here, the initial speed = u = 0
Now using v = u + at formula, we get
v = 0+ 3 × 5
=15 m/s
So, final speed is 15 m/s
Average speed is 15 m/s
Therefore, the final speed of a car is 15 m/s.

A statistician predicts that the probability of Wisconsin losing their next football game is 914. What are the odds for them winning? Write your answer as 1:2 which is reduced as much as possible.
Answers
Since the probability of them winning is 5/14, the odds of them winning is 5:14.
Probability of the team losing = 9/14
Probability of the team winning will then be: = 1 - 9/14 = 5/14
It should be noted that in order for us to get the probability of then winning, we have to subtract the fraction from 1 which was what was done above.
Therefore, it can be deduced that since the probability of them winning is 5/14, the odds of them winning is 5:14.

Answers
According to the word problem question;
If the salesperson earns 9 percent commission on sales;
In essence, 9/100 of the sales proceedings belongs to the salesperson.
Mathematically; the equation for the amount he or she earns in commission is;
c = 0.09swhere; c = commission and s = amount sold.Consequently, if the amount sold is $6,000;
The amount he or she earns in commission is;
c = 0.09 × $6,000c = $540.
The answer in ordered pair form is therefore;
(s,c) = ($6000, $540)

Sebastian was driving down a road and after 4 hours he had traveled 98 miles. At this
speed, how many hours would it take Sebastian to thrive 245 miles?
Fill out the table of equivalent ratios until you have found the value of x.
Answers
Answer:
Let x = speed for the first 96 miles
x - 9 = speed for the last 100 miles
Distance = (rate)(time), so time = (distance)/(rate)
(time for first part of trip) + (time for last part of trip) = 4 hours
So, (96)/(x) + (100)/(x - 9) = 4
Multiply both sides by the LCD (x)(x - 9) to get
96(x - 9) + 100x = 4x(x - 9)
96x - 864 +100x = 4x2 - 36x
4x2 - 232x + 864 = 0
Divide both sides by 4 to obtain x2 - 58x +216 = 0
(x - 4)(x - 54) = 0
x = 4 or x = 54
Note that x can't equal 4 because, in that case, x - 9 would be negative, so x = 54 miles per hour.
