She dips 9/20 in yellow
The part of the cloth that is dipped in both colours turns green.
Work out the fraction of cloth that turns green.
plz show working
Answer:
Fraction of cloth that turns green =
Step-by-step explanation:
Let total cloth be of length = 1 unit
Given of it is dipped in blue dye.
Fraction which is not dipped in blue is given as:
⇒
Taking LCD to subtract fractions.
⇒
⇒
She dips in yellow.
Comparing the fraction dipped in yellow which is and fraction which is not dipped in blue i.e.
Taking LCD between 8 and 20 = 40
We have:
Thus, we can say
Since , so the part dipped in yellow will also cover some part which is blue.
Thus, fraction dipped in yellow and blue which turns green will be given as:
⇒
Subtracting by taking LCD =40.
⇒
⇒
⇒ (Answer)
Answer:
20x+8
Step-by-step explanation:
in a rectangle, the sides opposite from each other are equal, and finding the perimeter means you going to add all the sides together
therefore we have
4x-1+4x-1+6x+5+6x+5=20x+8
The perimeter of a rectangular frame with sides of 4x - 1 and 6x + 5 is 10x + 4 units.
To find the perimeter of a rectangular frame, we add up the lengths of all the sides. In this case, the lengths of the sides are given as 4x - 1 and 6x + 5. Therefore, the perimeter can be found by adding these two sides together and simplifying the expression.
The perimeter = (4x - 1) + (6x + 5)
= 4x + 6x - 1 + 5
= (4 + 6) x + 4
= 10x + 4
So, the perimeter of the rectangular frame is 10x + 4 units.

The solution of the expression ''2 3/8 times 16'' will be 38.
What is an expression?
Mathematical expression is defined as the collection of the numbers, variables and functions by using signs like addition, subtraction, multiplication, and division.
Given that;
The expression is;
''2 3/8 times 16''
Now, We can formulate as;
⇒ 2 3/8 × 16
⇒ 19/8 × 16
⇒ 19 × 2
⇒ 38
Thus, The solution of the expression ''2 3/8 times 16'' will be 38.
