Navin gave his brother 1/5 of his money and her sister 5/8 of the remainder. Navin remained with $12.00 (a) Calculate how much m

MrRa [10]

Answer:

$40

Step-by-step explanation:

Fraction Navin gave his brother = 1/5

Remainder = 1 - 1/5

5/5 - 1/5 = 4/5

Fraction Navin gave his sister = 4/5 x 5/8 = 1/2

total amount Navin gave his siblings :

$\frac{1}{5} + \frac{1}{2}$

$\frac{2 + 5}{10}$ = $\frac{7}{10}$

Fraction that remains = 1 - 7/10

10/10 - 7/10 = 3/10

Let a = amount Navin has initially

3/10 x a = 12

a = (12 x 10) / 2 = $40

Which of the following describes the end behavior of f(x) = 2x 3x2 − 3 ? The graph approaches 0 as x approaches infinity. The gr

Arada [10]

1) An operator is missing in your statement. Most likely the right expression is:

 2x
f(x) = -------------
 3x^2 - 3

So, I will work with it and find the result of each one of the statements given to determine their validiy.

2) Statement 1: The graph approaches 0 as x approaches infinity.

Find the limit of the function as x approaches infinity:

 2x
Limit when x →∞ of ------------
 3x^2 - 3

Start by dividing numerator and denominator by x^2 =>

 2x / x^2 2/x
--------------------------- = ---------------
3x^2 / x^2 - 3 / x^2 3 - 3/x^2

 2/∞ 0 0
Replace x with ∞ => ------------ = ------- = ---- = 0
 3 - 3/∞ 3 - 0 3

Therefore the statement is TRUE.

3) Statement 2: The graph approaches 0 as x approaches negative infinity.

Find the limit of the function as x approaches negative infinity:

 2x
Limit when x → - ∞ of ------------
 3x^2 - 3

Start by dividing numerator and denominator by x^2 =>

 2x / x^2 2/x
--------------------------- = ---------------
3x^2 / x^2 - 3 / x^2 3 - 3/x^2

 2/(-∞) 0 0
Replace x with - ∞ => ------------ = ---------- = ---- = 0
 3 - 3/(-∞) 3 - 0 3

Therefore, the statement is TRUE.

4) Statement 3: The graph approaches 2/3 as x approaches infinity.

FALSE, as we already found that the graph approaches 0 when x approaches infinity.

5) Statement 4: The graph approaches –1 as x approaches negative infinity. 

FALSE, as we already found the graph approaches 0 when x approaches negative infinity.

$\\
\text{Suppose you have a quarter of a pie, so in mathematical notation the part of }\\
\text{pie you have is}=\frac{1}{4}\\
\\
\text{now you cut this piece of quarter pie in half and make two equal part.}\\
\\
\text{so the fraction of the pie, that each slice would represent is:}\\
\\
=\text{Half of the quarter pie}\\
\\
=\frac{1}{2}\left ( \frac{1}{4} \right )\\

=\frac{1}{8}$

Hence the fraction of a pie that each slice represent is: 1,8

sdas [7]

Answer:

Therefore,

$x+2=13$ .......Equation

Angelica's Brother's age is 11 years old.

Step-by-step explanation:

Given:

Let the current age of Angelica's Brother be 'x' years old

Angelica's current age is 13 years old,

According to given condition,

Therefore the Equation will be,

$x+2=13$

On solving this equation we get

$x=13-2=11\\\\x=11\ years$

Therefore,

Angelica's Brother's age is 11 years old.

Therefore,

$x+2=13$ .......Equation

Angelica's Brother's age is 11 years old.
