Answer:
a) 10%
Step-by-step explanation:
To be able to own both (20%), you must fall into both categories. You own a cellular mobile, and you own a landline. The 20% is within the 50% + 40%.
50% + 40% = 90%
Subtract 90% from the total amount:
100 - 90 = 10
A) 10% is your answer.

if x+1/x = 5 find the value of x^3 +1/x^3. pls solve
Answer:
1) solve x+1/x = 5
[tex] \frac{x + 1}{x} = 5[/tex]
[tex]x + 1 = 5x[/tex]
[tex]x - 5x = - 1[/tex]
[tex] - 4x = - 1[/tex]
[tex]x = \frac{ -1}{ - 4} [/tex]
[tex]x = \frac{1}{4} [/tex]
2) solve x³+1/x³
[tex]x {}^{3} + \frac{1}{x {}^{3} } [/tex]
substitute x = 1/4 into the expression
[tex]( \frac{1}{4} ) {}^{3} + \frac{1}{( \frac{1}{4}) {}^{3} } [/tex]
[tex] \frac{1}{64} + \frac{1}{ \frac{1}{64} } [/tex]
[tex] \frac{1}{64} + \frac{64 \times 1}{1} [/tex]
[tex] \frac{1}{64} + 64[/tex]
[tex] \frac{4097}{64} \: or \: 64.02[/tex]

Age of father is 30 years more than that of his son, 5 years hence fathers age will be thrice of his sons age. Find their present ages
Answer:
Son age be 10
And, the father age be 40
Step-by-step explanation:
The computation of the present ages is shown below:
Let us assume the son age be x
And, the father age be x + 30
Now after five hence, their ages are
Son age = x + 5
And, the father age be = x + 30 + 5
Also the father age is thrice of his son age
So the equation would be
3(x + 5) = x + 35
3x + 15 = x + 35
2x = 20
x = 10
The son age is 10
And, the father age is = 10 + 30 = 40
The correct ans is Five,
Let the son’s present age be x years.
Then the father’s present age is (x+30) years.
Father’s age after 5 years =(x+40) years
Son’s age after 5 years = (x+5) years
(x+40) = 3[x + 5]
x + 40 = 3x + 15
2x = 10
∴ x = 5

A garden is in the shape of a square with a perimeter of 36 36 feet. The garden is surrounded by two fences. One fence is around the perimeter of the garden, whereas the second fence is 3 3 feet from the first fence on the outside. If the material used to build the two fences is $ 1.32 $1.32 per foot, what was the total cost of the fences
Answer:
$110.88
Step-by-step explanation:
Let L be the length of the first fence surrounding the garden and P its perimeter.
For a square, P = 4L,
So, L = P/4
Since P = 36 feet,
L = P/4
= 36/4
= 9 feet
Let L' be the length of the second fence. Given that second fence is 3 feet away from the first fence, it follows that L' = L + 3
= 9 + 3
= 12 feet.
So, the perimeter of the second fence is P' = 4L'
= 4 × 12 feet
= 48 feet.
So, the total length of the two fences is P" = P + P'
= 36 feet + 48 feet
= 84 feet
Since the cost of the material to build the two fences is $1.32 per foot, the total cost of the fences is cost per foot × total length of fences = $1.32 × 84 = $110.88

Answer:
95.80
Step-by-step explanation:
The number 23/24 rounded to the nearest hundredth is 0.96
What is rounding up numbers?
There are basically two rules while rounding up numbers
If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down and if the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.
Given data ,
Let the number be A = 23/24
So , in order to round the number
First we need to find the decimal for of the number A
And ,
A = 23/24
A = 0.9583
And , rounding the number to its nearest hundredth is rounding the number to two decimal places
So ,
A = 0.9583
A = 0.96
Hence , The number 23/24 rounded to the nearest hundredth is 0.96

Based on his skills in basketball, it was computed that when Joe Sureshot threw a free throw, the odds in favor of his making it were 4 to 35. Find the probability that when Joe shot a free throw, he made it. Out of every 100 free throws he attempted on the average how many did he miss?
Answer:
11.43%
89 free throws would miss
Step-by-step explanation:
In order to find the percentage probability of Joe making a free throw show we need to the odds given and then multiply that decimal value by 100 like so...
4 / 35 = 0.11428
0.11428 * 100 = 11.43% rounded up
If Joe were to shoot 100 free throws 11.43% would most likely go in but since the actual number can only be a whole number it would mean that 11 of those 100 free throws would go in.
100 - 11 = 89
Therefore, 89 free throws would miss on average.
