[tex]Q13)[/tex] [tex]\frac{\sqrt{11} - \sqrt{5} }{\sqrt{11}+\sqrt{5} }[/tex] = [tex]x - y\sqrt{55}[/tex]
LHS :-
= [tex]\frac{\sqrt{11} - \sqrt{5} (\sqrt{11}-\sqrt{5}) }{\sqrt{11}+\sqrt{5} (\sqrt{11}-\sqrt{5}) }[/tex]
= [tex]\frac{11-2\sqrt{55}+5 }{11 - 5}[/tex]
= [tex]\frac{16-2\sqrt{55} }{6}[/tex]
= [tex]\frac{2(8-\sqrt{55}) }{2(3)}[/tex]
= [tex]\frac{8-\sqrt{55} }{3}[/tex]
=> x = 8/3 and y = 1/3
=> Option B
[tex]Q14)[/tex] [tex]\frac{4}{216^{-2/3} }[/tex] + [tex]\frac{1}{256^{-3/4} }[/tex] + [tex]\frac{2}{243^{-1/5} }[/tex]
= 4 x (∛216)² + ([tex]\sqrt[4]256}[/tex])³ + 2 x ([tex]\sqrt[5]{243}[/tex])
= 4 x 36 + 64 + 2 x 3
= 144 + 64 +6
= 144 + 70
= 214

Answer:
c=30
Step-by-step explanation:
Inverse: 22 + 8 = 30
c = 30
Answer:
c = 30
Step-by-step explanation:
Step 1: Add 8 to both sides.
[tex]c-8+8=22+8[/tex] [tex]c=30[/tex]Step 2: Check if solution is correct.
[tex]30-8=22[/tex] [tex]22=22[/tex]Therefore, the answer is c = 30.
Evaluate the equation.
12.8 + c = 30.12
A. c =17.28
B. c =17.32
C. c =42.92
D. c =43.02
Answers
Answer: B. c = 17.32
Step-by-step explanation:
12.8 + c = 30.12
c = 17.32 [Subtract 12.8 from both sides.]
Therefore, answer is B.

10% of 22 = 2.2
2.2 x 2 = 20% = 4.4
2.2/2= 5% =1.1
4.4+ 1.1

Answer:
The answer is 6
Step-by-step explanation:
2.3... where the 3s go on forever is the same as 2 + 1/3 or 2 & 1/3
The whole number portions add to 3+2 = 5, and we add on the carry of 1 to get 5+1 = 6
3 & 2/3 = 3 + 2/3 = 3 + 0.667 = 3.667 approximately
adding this onto 2.333 leads to
3.667 + 2.333 = 6
Technically the 6's go on forever in the decimal form of 3 & 2/3, but rounding wont have an effect on the answer when we add

Answer : 5 x 4 (Option C)
Step-by-step explanation : 5 + 5 + 5 + 5 = 20
By trial & error method, we get
5 x 2 = 10 ≠ 20
5 x 4 = 20
5 x 5 = 25 ≠ 20
5 x 10 = 50 ≠ 20
Hence 5 x 4 is the right answer
You can either follow the trial & error method or the following method !!
5 + 5 + 5 + 5 has ' 4 ' fives
Hence, 5 + 5 + 5 + 5 = 5 (since it is the no) x 4 (since it is the no of times 5 is repeating)
Hence 5 x 4 is the right answer

what is the approximate height of the rice container if the radius is 2.5 in. and the volume is 235.5 in cubed
Answers
Answer:
12 in
Step-by-step explanation:
r = 2.5 in
V = 235.5 in³
Find h
Use V = πr²h
so 235.5 = 3.14 * 2.5² * h
235.5 = 19.625 h
h = 235.5/19.625 = 12 in

The area of a rectangle is 75 square feet, and the length is 25 feet. What is the perimeter?

this is another side.
(3+25)x2+56 feets
Answer:
75ft.
Step-by-step explanation:
What you do is subtract two 25s from the area (because there are two sides for length) which gives you 25. The width would be half of that which is 12.5. Then add two widths (12.5+12.5=25), and add that to two lengths (25+25=50). The answer is 75ft as well. Please tell me if I'm wrong.
