Answer:
The answer is B 11/20
Step-by-step explanation:
To transform a decimal to a fraction you must do the following:
1. Multiply by an specific power of 10 until your decimal becomes a whole number. In this case 0.55 we multiply by 10 ^2 or 100 and we obtain 55.
2 Divide the decimal by this same power of 10 so that you do not change the original value. For example
0.55 *(100/100) = 55/100 As you see Im multiplying and dividing by 100 ( thats equivalent to 1 so it doesnt change the original number)
3 Simplify the fraction
To simplify your fraction you must find the Greatest Common Factor of 55 and 100. For doing this, you only perform a prime factorization. Divide 55 and 100 by the smallest common prime factor, besides 1. (For this case is 5) until you arrive to two number without common prime factors.
55/5 = 11
100/5 = 20
As 11 and 20 have no common prime factors it is the most simplified fraction

the rational roots of a polynomial function F(x) can be written in the form p/q,
where p is a factor of the constant term of the polynomial, and q is a factor of the leading coefficient
TRUE OR FALSE??
ANSWER
True
EXPLANATION
According to the Rational Roots Theorem,the rational roots of a polynomial function F(x) can be written in the form
[tex] \frac{p}{q} [/tex]
,
where p is a factor of the constant term of the polynomial, and q is a factor of the leading coefficient.
The polynomial must be written in standard form.
This means the polynomial must be written in descending powers of x.
The leading term is the first term of a polynomial written in standard form.
The constant term is the term independent of x.

13x +9 and 5x+9 are consecutive exterior angles.
Consecutive exterior angles are supplementary.
[tex]13x+9+5x+9= 180[/tex]
Now we solve for x. combine like terms
[tex]18x+18= 180[/tex]
Subtract 18 from both sides
[tex]18x=162[/tex]
Divide both sides by 18
x=9
So the value of x=9
angle 6 and 5x+9 are vertical opposite angles . they are equal
m<6= 5x+9
Plug in 9 for x
m<6= 5(9)+9=54
m<6 = 54
Answer:
m<6 = 54

The probability of picking two black marbles from a box at random without replacement is 1091 . The probability of drawing a black marble first is 514 . What is the probability of picking a second black marble, given that the first marble picked was black?
Final answer:
The probability of picking a second black marble, given that the first marble picked was black, is 1.
Explanation:
To find the probability of picking a second black marble, given that the first marble picked was black, we can use the formula for conditional probability: P(A|B) = P(A and B)/P(B).
In this case, A represents the event of picking a black marble on the second draw, and B represents the event of picking a black marble on the first draw.
We are given that P(B) = 514, and the probability of picking two black marbles without replacement is 1091. Therefore, P(A and B) = P(A|B) * P(B) = (1091/514) * (514/1091) = 1.
So, the probability of picking a second black marble, given that the first marble picked was black, is 1.

A man weighs 180 lb. He jogs a mile in 8 minutes. How many calories has he used up?
A man weighing 180 lb has burned approximately 100 calories by jogging one mile, based on the average estimate that jogging one mile burns almost 100 calories.
The question relates to the calculation of calories burned during exercise, specifically jogging. Based on the information provided that running or jogging one mile burns almost 100 calories, we can calculate the energy expenditure for a man weighing 180 lb who jogs a mile in 8 minutes.
Since the provided calories burned per mile is an average, the actual number might vary slightly based on individual metabolism and effort level, but it serves as a useful approximation.
To determine how many calories the man has used up, we can use the given information:
Running or jogging one mile burns almost 100 calories.The man jogs a mile, which means he has burned approximately 100 calories for that activity.Therefore, the man has burned approximately 100 calories during his 8-minute mile jog.
What is the length of segment CE if AE = 15 inches and ED = 5 inches and EB = 3 inches?
A. 45 inches
B. 9 inches
C. 15 inches
D. 14 inches
We have to determine the length of segment CE if AE = 15 inches and ED = 5 inches and EB = 3 inches.
Since ,we can observe that AB and CD are chords intersecting at point E.
Therefore, by intersecting chord theorem which states:
" When two chords intersect each other inside a circle, the products of their segments are equal"
So, [tex] AE \times EB= CE \times ED [/tex]
[tex] 15 \times 3= CE \times 5 [/tex]
[tex] 45= CE \times 5 [/tex]
[tex] CE = \frac{45}{5} [/tex]
CE = 9 inches.
So, the measure of segment CE is 9 inches.
So, Option B is the correct answer.

Difference between ellipse circle parabola and hyperbola equations
The solution is: these have a subtraction operation, the exact opposite ellipse.
What is parabola?The parabola is a plane curve which is mirror symmetrical and is approximately U-shaped. It fits several superficial different mathematical descriptions.
here, we have,
The equation of a circle is:
(x - h)² + (y - k)² = r²
The equation of a parabola is:
(x - h)² = 4p(y - k)
The equation of an ellipse is:
(x - h)²/ a² + (y - k)²/ b² = 1
where variables a and b and the two different measurements of the vertices
The equation of a hyperbola is:
(x - h)²/ a² - (y - k)²/ b² = 1 if it is with a horizontal transverse axis
(y - k)²/ b² - (x - h)²/ a² = 1 if it is with a vertical transverse axis
Notice these have a subtraction operation, the exact opposite ellipse.

Jamestown Builders has a development of new homes. there are 6 different floor plans 7 exterior color than an option of either one car or two car garage . How many choices are there for one home?
if no digit may be used more than once how many 5 digits can be formed using only three digits. 8 1 2 5 and7?
The answer provides the experimental probability of selecting green or purple marbles, predicts the occurrences of rolling 3 or 5 on a number cube, and estimates the total number of people who enjoyed the movie.
Experimental Probability Calculation: In the given scenario, there are 8 green marbles and 2 purple marbles, making a total of 10 marbles. The probability of selecting a green or purple marble is the sum of the individual probabilities, which is (8/10) + (2/10) = 0.8.
Expected Outcome of Rolling a Number Cube: Since a standard number cube has numbers 1 to 6, each number has an equal probability of 1/6. Predicting how many times 3 or 5 will be rolled out of 180 rolls can be calculated by (1/6 + 1/6) x 180 = 60 times each for 3 and 5.
Total Number of People Who Enjoyed the Movie: Based on the sample data, 4,200 out of 8,000 people enjoyed the movie. Extrapolating this to the total viewers, the predicted number of people who enjoyed the movie would be: (4,200/8,000) x 500,000 = 262,500 people.

The prime factorization of 18 is 2 x 3², dividing 18 first by 2 and then by 3 twice.
Explanation:The prime factorization of a number represents that number written as the product of its prime factors. Let's take 18 as an example. First, we will find the smallest prime number that can divide 18, which is 2. When 18 is divided by 2, the quotient is 9. Then, we continue to divide 9 by the smallest possible prime number, which is 3. We can divide 9 by 3 two more times. Therefore, the prime factorization of 18 is 2 x 3², where 2 and 3 are the prime factors and ² is an exponent indicating that 3 is a factor twice.
