A room has to be painted and worker A does 1/3 of the work then leaves. Next worker B does 1/4 of the remaining work and then leaves and finally worker C does 1/5 of the remaining work and then leaves.
What fraction of the room still needs to be painted?
a)3/5
b)2/5
c)13/60
d)7/15

Answers

Answer 1
The Answer is C 13/60
Answer 2
S O L U T I O N :

Here, we are given that a room is painted by A, B and C so here three of them have done the work. So, we'll add all these fractions and assume the total work as 1 after that we will substract all the added ones from 1

Let us assume the room completely painted be 1

Now,

A has done 1/3, B has done 1/4 and C has done 1/5 work of the remaining

So, let us add them

A + B + C

⅓ + ¼ + ⅕

Getting the L.C.M. The L.C.M of 3,4,5 is 60

20/60 + 15/60 + 12/60

47/60

Hence, 47/60 room has been painted

Remaining to paint

Total is assumed as 1

Work done = 47/60

Fraction of room needs to painted = 1 - 47/60

(60 - 47)/60

13/60

13/60 of the room needs to be painted, OPTION C IS CORRECT

In the 2007–2008 season,
Dwayne Wade made 439 field goals out
of 937 attempts. What was Dwayne
Wade’s ratio of successful field goals to
attempts? Write your answer as both a
fraction in simplest form and a decimal
rounded to the nearest thousandth.

Answers

Answer:

Step-by-step explanation:

Answer as a fraction = 439/937

Answer as a decimal = 0.469

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

Explanation:

He made 439 baskets out of 937 attempts. So we simply form the fraction 439/937. The number of makes or successes is up top, while the number of attempts is at the bottom. The order is important.

Both 439 and 937 are prime numbers. This means the faction 439/937 cannot be reduced. So we leave it as is.

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

You can use a calculator or long division to find that

439/937 = 0.4685

which is approximate. Rounding to the nearest thousandth (i.e. 3 decimal places) will lead us to 0.469

If we were to move the decimal 2 spots to the right, then we convert to percent form and that's roughly 46.9%

Answers

9514 1404 393

Answer:

  B.  2 x (6 + 9) = (2 x 6) + (2 x 9)

Step-by-step explanation:

The distributive property says the product is the sum of the products of the outside factor with each of the terms inside parentheses. In generic form:

  a(b +c) = ab +ac

Here, we have a=2, b=6, c=9.

  2(6 +9) = 2(6) +2(9)

Which of the following angles DOES NOT have equal measure when a pair of parallel lines is crossed by a transversal?

Answers

Answer: we might have come across different types of lines such as parallel lines, perpendicular lines, intersecting lines, and so on. Apart from that, we have another line called transversal.                                                                                    

This can be observed when a road crosses two or more roads or a railway line crosses several other lines. These give a basic idea of a transversal. Transversals play an important role in establishing whether two or more other lines in the Euclidean plane are parallel.

In this article, you will learn the definition of transversal line, angles made by the transversal with parallel and non-parallel lines with an example.  

SOOO in English its LM is the transversal made by the parallel lines PQ and RS such that:

The pair of corresponding angles that are represented with the same letters are equal.

If two parallel lines are cut by a transversal, each pair of alternate interior angles are equal. Transversal property 2

PLEASE HELP ME
I NEED HELP!

Answers

Answer:

2nd - (w - 5)(w + 5)

4th - (-4v - 9)(-4v + 9)

Step-by-step explanation:

1. The first option shows an expression multiplied by its opposite(x -1), so therefore, it does not show the difference of squares

2. The second option does show the difference of squares because it is in the form (a + b)(a - b)

3. The third option is just a square because the same expression is multiplied by itself.

4. The fourth option is the difference of squares because it is in the form (a + b)(a - b). a equals -4v and b equals 9 in this case.

5. The fifth option is not the difference of squares. No term in common in both expressions

6. The sixth option is just a square because the same expression is multiplied by itself.

In all, there are two options that are the difference of squares, the 2nd and 4th.

Okay so you multiply with the 4 outside of the parentheses

8a
4 times 3 is 12

4 times 4 is 16

So the answer is B
