Write as a product of two polynomials.
x(y–5)–y(5–y)

Answers

Answer 1

Final answer:

The expression x(y-5) - y(5-y) can be rearranged and factored into (y - 5)(x + y), which is the expression written as a product of two polynomials.

Explanation:

To write the expression x(y-5) - y(5-y) as a product of two polynomials, we first distribute the variables across each term:

x(y-5) = xy - 5x

-y(5-y) = -5y + y²

Now, combining like terms:

xy - 5x - 5y + y²

This expression can't be factored as is, since it cannot be represented by the product of two simpler polynomials with real coefficients. However, we can rearrange the terms:

(xy - 5y) + (y² - 5x) = y(x - 5) + y(y - 5)

Here we can see a common factor of (y-5):

(y - 5)(x + y)

This is the expression written as a product of two polynomials.

Answers

A charter is to a city government as a state constitution is to a state government.

Answer: Option D

Explanation:

Apart from the national level constitution, in the United States of America, every state has its own constitution. They are more detailed when compared to the national constitution as they tend to have more words or content when compared to the national level constitution.

The shortest one belongs to Vermont and the longest one belongs to Alabama. These constitutions tell how the government of each state must function and carry out its day to day activities.

Answers

Final answer:

The given mathematical equation, 0x4=0, can be turned into a word problem concerning a person with no money multiplying his funds. The result, as the equation suggests, is still no money, demonstrating that anything multiplied by 0 equals 0.

Explanation:

Let's create a word problem for the equation 0x4=0. Suppose Jack has no money (0 dollars) and he multiplies his money by 4. How much money does Jack have now? The equation to represent this situation is 0x4=0. That is, 0 (Jack's money) times 4 equals 0. So, Jack still has no money. This shows that anything multiplied by 0 is always 0, a fundamental rule in mathematics.

Find the LCM of the pair of numbers. 6 and 9 The LCM is .

Answers

Answer:

So the LCM of 6 and 9 is 18.

Step-by-step explanation:

List the factors of both numbers.

6: 6, 12, 18, 24, 30, 36,

9: 9, 18, 27, 36

The LCM of 6 and 9 is found by prime factorizing each number and taking the highest power of each prime that appears, resulting in an LCM of 18.

To find the LCM (Least Common Multiple) of the pair of numbers 6 and 9, we first need to prime factorize each number. The number 6 can be prime factorized as 2 times 3, and 9 can be prime factorized as 3 times 3 or 3². In order to find the LCM, we take the highest power of each prime number that occurs in the factorization of both numbers. So, we take 2 from the factorization of 6 (since it's the highest power of 2) and 3² from the factorization of 9 (since it's the highest power of 3), and multiply them together to get the LCM.

The LCM of 6 and 9 is 2 times 3² = 2 times 9 = 18.

Thus, the Least Common Multiple of 6 and 9 is 18.

A math class has 5 girls and 5 boys in the seventh grade and 5 girls and 7 boys in the eighth grade. The teacher randomly selects a seventh grader and an eighth grader from the class for a competition. What is the probability that the students she selects are both girls? Write your answer as a fraction in simplest form.

Answers

Final answer:

The probability that the students selected are both girls is 5/24.

Explanation:

To find the probability that both students selected are girls, we need to calculate the probability of selecting a girl from the seventh grade and a girl from the eighth grade and then multiply those probabilities together.

The probability of selecting a girl from the seventh grade is 5 girls out of 10 students, which can be expressed as 5/10 or 1/2.

The probability of selecting a girl from the eighth grade is 5 girls out of 12 students, which can be expressed as 5/12.

To find the probability of both events happening, we multiply the probabilities together: (1/2) * (5/12) = 5/24.

Therefore, the probability that the students selected are both girls is 5/24.

Hope this helps!

Final answer:

The area of the triangle is found by recognizing that it is a special 30-60-90 triangle with sides in the ratio of 1: √3 : 2. The area, using these ratios and the given perimeter, is calculated as 25√3 square units.

Explanation:

This problem pertains to the area of a triangle. Because we know the two acute angles of triangle ABC, it is a 30-60-90 triangle. This is a special type of right triangle where the sides are in a particular ratio. In a 30-60-90 triangle, the sides across from the 30°, 60° and 90° angles are in the ratio of 1: √3 : 2.

Given that the perimeter is 5(3 + √13), we can set up the ratio for the sides as x, x√3, and 2x. Adding these together equals the perimeter: x + x√3 + 2x = 5(3 + √13). Solving this equation, we find x = 5.

The area of a triangle is calculated using the formula 1/2*base*height. Using the sides of the triangle, 5, 5√3, and 10, we will use the side across from the 90° angle (10) as the base and the side across from the 60° angle (5√3) as the height, giving us a triangle area of 1/2 * 10 * 5√3 = 25√3 square units.

RSM QUESTION NEED HELP!!!!!! A biker traveling at his usual speed can go from his house to work in 4 hours. When the weather is bad, he travels 6 miles per hour slower, and it takes him half an hour more. How far is his work from his house?

Answers

Answer:   216 miles

=======================================

Work Shown:

d = distance from work to his house

x = speed when weather is good

y = speed when weather is bad

y = x-6 since he travels 6 mph slower

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

On a good weather day, he travels for 4 hours and goes at x mph

distance = rate*time

d = r*t

d = x*4

d = 4x

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

On a bad weather day, he travels 4.5 hours (half hour more than 4 hrs) and goes at y = x-6 mph

d = r*t

d = y*4.5

d = 4.5y

d = 4.5(x-6) .... replace y with x-6

d = 4.5x-27 .... distribute

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

The values of d for both equations are the same, as the biker is traveling the same distance. So we can equate the two right hand sides (RHS) and solve for x.

4.5x-27 = 4x

4.5x-4x = 27

0.5x = 27

x = 27/0.5

x = 54

The biker's speed on a good weather day is 54 mph.

A bad weather day's speed would be y = x-6 = 54 - 6 = 48 mph.

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

Now compute the value of d

d = 4x

d = 4*54

d = 216

The biker travels 216 miles on a good weather day

or,

d = 4.5*y

d = 4.5*48

d = 216

the biker travels that same distance on a bad weather day.

a taxi driver earns $9 per 1 hour work. if he works 10 hours a day and in 1 hour he uses 2-liters petrol with price $1 for 1-liter. how much money does he earn in one day?
a. 90
b. 88

Answers

if he makes 9 an hour and works 10 hours a day, he makes 90 a day. every hour, he uses 2 liters of petrol, two dollars, so take two dollars off every hour. he makes 7 an hour. 7 times 10 is 70, or c.

Final answer:

The taxi driver earns $70 in one day after deducting the cost of petrol from his gross income.

Explanation:

To calculate the taxi driver's earnings, we need to consider his hourly wage, the number of hours worked, and the cost of petrol used during the day. The driver earns $9 per hour and works for 10 hours a day. Thus, his total gross income for the day is $90 (9 dollars/hour times 10 hours). However, he also uses petrol for which he incurs a cost. He uses 2 liters per hour, and since petrol costs $1 per liter, he spends $2 per hour on petrol. Over 10 hours, he thus spends $20 on petrol (2 dollars/hour times 10 hours). To find his net earning, we subtract the petrol cost from the gross income: $90 - $20, which equals $70.

A store has a display case with cherry, peach,

in the display case. Given that 25% of the fruit
chews are cherry and 40% are peach, how many
grape fruit chews are in the display case?

Answers

Answer:

56 grape

Step-by-step explanation:

160 fruit chews

25% are cherry, 40% are peach.....25 + 40 = 65%....so 65% of the fruit chews are NOT grape....meaning (100 - 65) = 35 % ARE grape.

so 35% of all the fruit chews are grape

35% of 160 = 0.35 * 160 = 56 are grape <===

The number of grape fruit chews in the display are 56.

To find the number of grape fruit chews in the display case:

Calculate the percentage of cherry and peach fruit chews: 25% cherry + 40% peach = 65% cherry and peach combined.

Subtract the combined percentage from 100% to find the percentage of grape fruit chews: 100% - 65% = 35% grape.

Calculate the number of grape fruit chews by finding 35% of 160 (total fruit chews): 35% of 160 = 0.35 x 160 = 56 grape fruit chews.

A moose population is growing exponentially following the pattern in the table shown below. Assuming that the pattern continues, what will be the population of moose after 12 years? Show all your work! Round your answer to the nearest whole number. (5 points)

Answers

The table referred to in the question is:

years=x population =y

 0                  40

 1                  62

 2                 96

 3                149

 4                231

Answer:

7,692 moose

Explanation:

To discover the pattern followed by the data in the table, since it is indicated that the moose population is growing exponentially, you can find the multiplicative rate by dividing any two consecutive terms:

rate = 62/40 ≈ 96/62 ≈ 149/96 ≈ 231/149 ≈ 1.55

Thus, using the first ordered pair of the sequence, (0,40), you get the equation that models the exponential growing:

[tex]p(x)=A_0(1.55)^{x}\\ \\ 40=A_0(1.55)^0\\ \\ 40=A_0\times 1\\ \\ A_0=40\\ \\ p(x)=40(1.55)^x[/tex]

Then, to find the population of moose after 12 years, you substitute x = 12:

[tex]p(12)=40(1.55)^{12}=7,692[/tex]
