As botanist is studying the effect of water and fertilizer on certain flowering plants.
Three Distinct amounts of water having different amount of fertilizer contents in them is used for the purpose of Experimentation.
That is, Plants are given 8, 16, or 32 ounces of water each day, and the water that is given contains either a 2%, 5%, or 10% dissolved fertilizer solution.
Number of treatments used in this experiment taking 8, 16, or 32 ounces of water each day taking two at time= that is (8,16),(16,8),(8,32),(32,8),(16,32),(32,16).
So, Number of treatments used in this experiment taking 8, 16, or 32 ounces of water each day taking all at time =
that is (8,16,32) , (8,32,16),(16,8,32),(16,32,8),(32,8,16),(32,16,8)
These are the orders in which water is used for flowering the plants that is first day 8 ounces of water, second day 16 ounces of water, third day 32 ounces of water, or first day 8 ounces of water, second day 32 ounces of water, third day 16 ounces of water, ...........
So, there are 6 possible arrangements using (8, 16 and 32 ) ounces of water taking all at a time and 6 possible arrangements using (8, 16 and 32 ) ounces of water taking two at a time.
Or there are total of [6 × 3= 18] + [6 × 2= 12],=30 treatments.
Answer:
The lengths of sides of squares are 5 cm and 9 cm.
Step-by-step explanation:
Let the sides of rectangle be x and y .
Area of rectangle = Length × Breadth
Given : Area of rectangle = 45 cm².
⇒ x × y = 45
⇒ ........(1)
Two squares are constructed such that two adjacent sides of the rectangle
so squares have side x and y .
Area of square = side × side
Area of square with side x = x²
Area of square with side y = y²
Also, The combined area of the two squares is 106 cm².
⇒ x² + y² = 106
From (1) put value of x , we get,
Solving for y ,
or
on solving we get y = 5 and y = 9
Also, x can be find by putting in (1),
⇒ and ⇒
⇒ x = 9 and x = 5
Thus, lengths of sides of squares are 5 cm and 9 cm.
Answer:
<h2>(0,1) and (2,5).</h2>Step-by-step explanation:
The graph of the inequality is attached.
Remember, a solution of an inequality is a point on the shaded region. Also, it must satisfy the inequality expression
From the graph we know the possible answers are (0, 1) and (2, 5), let's prove it.
<h3>For (0, 1):</h3>Which is true, so (0, 1) is solution.
<h3>For (2, 5):</h3>Which is true, so (2, 5) is solution.
Therefore, the solutions are (0,1) and (2,5).
