Two men can do a work in 4 days and 6 days respectively how many days will it take if they work togatherpls tell with steps ill mark brainlist

Answers

Answer 1

Answer:

The answer is 12/5 days

Step-by-step explanation:

The First Man (FM) takes 4 days to complete the work

In one day he does (1/4)th portion of the work

The Second Man (SM) takes 6 days to complete the work

In one day he does (1/6)th portion of the work

The FM and SM together do [ (1/4 ) + ( 1/6) ] th portion of the work

So , [ (3+2 )/12] = ( 5 / 12 ) = 5/12 th portion in one day

Hence, FM and SM together complete the work in 12/5 = 2.4 days

When the full season tickets first went on sale,2,000 Full season tickets sold for Section N. Two weeks after the tickets first went on sale, another 1,500 full season tickets were sold for section N. How much money spent on full season tickets for section N in total? How much more money was spent when the tickets first went on sale than after the first two weeks.

Answers

Image showing the arena ticket prices is missing, so i have attached it.

Answer:

$10000 more money was spent when the tickets first went on sale than after the first 2 weeks

Step-by-step explanation:

We are told that when the full season tickets first went on sale, that 2000 full season tickets were sold for section N.

Now, from the area ticket prices table attached, we can see that full season tickets for Section N costs $20

Thus, amount of money spent when the tickets first went on sale = 2000 × 20 = $40000

We are told that 2 weeks after the tickets first went on sale, they sold 1500 tickets. Thus, amount spent after 2 weeks release = 1500 × 20 = $30000

Difference in amount spent at the beginning and after 2 weeks = $40000 - $30000 = $10000

Thus, $10000 more money was spent when the tickets first went on sale than after the first 2 weeks

If the question is how many variable terms are in 3x^3y + 5x7 - 4y + x-z+9 the answer would be 7 because each of the variables are separated by the + and - signs and if you count them like that right now you would get 5 and if you add the 3 from the beginning you would get 7 saying that the variable terms are represented by the letters am I correct.

Answers

Given:

The expression is

[tex]3x^3y+5x^7-4y+x-z+9[/tex]

To find:

The number of variable terms.

Solution:

Constant values, variables, product of constants and variables are known as terms if they are separated by  "+" sign.

The terms which contain atleast one variable is called variable terms.

We have,

[tex]3x^3y+5x^7-4y+x-z+9[/tex]

Here, the terms are [tex]3x^3y,5x^7,-4y,x,-z[/tex] and 9.

All terms contain variables except 9 which is a constant.

Therefore, the number of variable terms is 5.

Hence, your answer was not correct.

Given that R = 3x + 9y
Find x when y = 6 and R=7
Give your answer as an improper fraction in its simplest form.​

Answers

Answer:

Step-by-step explanation:

R = 3x + 9y

They told us that R = 7, y = 6

So you can rewrite the equation as:

R = 3x + 9y

7 = 3x + 9(6)

7 = 3x + 54

Subtract 54 from both sides.

7 - 54 = 3x

-47 = 3x

To find x, you need to divide both sides by 3

3x = -47

x = -47/3

Does (12+6)÷2 and 12+6÷2 have the same answer

Answers

Answer:

No

Step-by-step explanation:

If you go by PEMDAS then you would do whatever is in the parenthesis first, which in this case would be 12 + 6. And then you would divide, so 12 + 6 = 18/2 = 9. In the other equation you would do division first, so that would be 6/2 which equals 3 and then you would add that to 12 which equals 15.

Answer:

No, because it has parentheses. You have to do the parentheses first (cause of order of operations) and the divide, (or based on whatever your step is from order of operations) which your going to get a diff answer.

You can ignore a and b but can someone help me with c and d plz :)

Answers

Answer:

(below)

Step-by-step explanation:

c) the angles are in the interior on the same side of the transversal, making them supplementary

equation: 2x + 20 + 120=180 and then when solved you would get x =20

d) the angles are corresponding, which makes them congruent

equation: 3x + 10 = 100 and then when solved you would get x = 30

For C, the answer is x = 20. Explanation: the sum of the two angles is equal to 180 degrees, since they are across parallel lines. Plug the two angles into an equation that equals 180. You should have (2x + 20) + 120 = 180. Simplify the equation by subtracting 120 from both sides. You should now have 2x + 20 = 60. Subtract 20 from both sides. 2x = 40. Now simplify the equation by dividing both sides by 2, and you get your answer, x = 20. The answer for D is x = 30. Explanation: Since the angles are on the same side of parallel lines, they are equal. Plug the angles into an equal equation: 3x + 10 = 100. Subtract 10 from both sides to get 3x = 90. Now divide both sides by 3 to get your answer, x = 30.

Here s = 16, thus

A = [tex]\frac{16^2\sqrt{3} }{4}[/tex]

Which function is a horizontal translation of the parent quadratic function, f(x) = x2
O A. ;(z) = x2 - 4
B. g(x) = (x - 4)
C. k(x) = -42
D. h(x) = 4,2

Answers

The function that represents the horizontal translation of the parent function is (b)g(x) = (x - 4)^2

How to determine the horizontal translation?

The function is given as:

f(x) = x^2

An horizontal translation is represented using:

f'(x) = (x ± h)^2

Where h does not equal to 0

From the list of options. we have:

g(x) = (x - 4)^2

Hence, a function that represents the horizontal translation of the parent function is (b)g(x) = (x - 4)^2

The speed of a body falling freely from rest in a vacuum varies directly with the length of the time it falls. If after 6 seconds, a body was falling 58.8 m/s, how fast was it falling 4 seconds later? (Round off your answer to the nearest meter per second.)

Answers

Answer:

The body is falling at 98 m/s after 4 seconds later.

Step-by-step explanation:

The magnitude of the speed of a body dropped from rest is:

[tex] v = gt [/tex]

So, if the speed of a body dropped after 6 seconds is 58.8 m/s, after 4 seconds later is:

[tex] v = gt = 9.81 m/s^{2}*(4s + 6s) = 98.1 m/s = 98 m/s [/tex]

Hence, the body is falling at 98 m/s after 4 seconds later.

Find the measure of angle b

explanation:

b and 50 are supplementary angles (they add up to 180), so create an equation by adding them up to equal 180:

b + 50 = 180

we want the x by itself, so subtract both sides by 50 to get:
