Using the area, the number of tiles needed to cover the floor is 6.
<h3>What is area?</h3>
The area is the region bounded by the shape of an object.
Therefore, the bathroom floor measures 3 yards by 3yards.
Hence the area of the bathroom floor can be calculated as follows;
area of the bathroom floor = 3 × 3
area of the bathroom floor = 9 yards²
The area of the custom tiles that makes the flooring is 1 1 /2 square yards.
Hence,
number of tiles needed to cover the floor = 9 ÷ 3 /2
number of tiles needed to cover the floor = 9 × 2 / 3
number of tiles needed to cover the floor = 18 / 3
number of tiles needed to cover the floor = 6

The concentration of ions in the solution of lemon juice whose pH value is 2.32 is 4.79×10⁻³ M.
<h3>What is pH value?</h3>
The pH value shows that how much a solution is acidic or basic. The range of the pH value lies between the 0-14.
The pH value can be calculated with the following formula.
![\rm pH=log[H^{+}]](https://tex.z-dn.net/?f=%5Crm%20pH%3Dlog%5BH%5E%7B%2B%7D%5D)
Here, [H⁺] is the molar hydrogen ion concentration.
The pH of lemon juice at 298 K is found to be 2. 32. Put this value of pH in the above formula as,
![\rm 2.32=log[H^{+}]\\\ [H^{+}]=4.79\times10^{-3} \rm \; M](https://tex.z-dn.net/?f=%5Crm%202.32%3Dlog%5BH%5E%7B%2B%7D%5D%5C%5C%5C%20%5BH%5E%7B%2B%7D%5D%3D4.79%5Ctimes10%5E%7B-3%7D%20%5Crm%20%5C%3B%20M)
Hence, the concentration of ions in the solution of lemon juice whose pH value is 2.32 is 4.79×10⁻³ M.

(a+b)(a-b) = a^2 - b^2
(1+5/6) (1-5/6) = 1^2 - (5/6)^2 = 1 - 25/36 = 36/36 - 25/36 = (36-25)/36 = 11/36
11/36 is your answer
Answer: 40 cm
So the diagonal formula is - 1/2* (d1*d2) d1 is the first diagonal and d2 is the second diagonal.
So,
1/2 * (18*d2)= 360
18*d2= 360*2
d2= 720/18
d2= 40
Answer:
(x+6) feet, 110sq ft
Step-by-step explanation:
Area = width * length = something * (x + 7)
Width = (x+6) as 6 and 7 add to 13 and times to 42.
To confirm expand (x+6)(x+7)=x^2+6x+7x+42=x^2+13x+42
(x+6) feet
4^2+13(4)+42=16+52+42=110 sqft
