Answer:

cos B

Step-by-step explanation:

Let us take a look at angle B

The side adjacent angle B is 24 while the hypotenuse (the side facing the right angle) is 25

The relationship between the adjacent and the hypotenuse can be mapped our using the cosine

So, the cosine is the ratio between the adjacent and the hypotenuse

Hence, cos B = 24/25

Solve <br>In 2x + In 2=0

Solving $ln(2x)+ln(2)=0$ we get, $x=\frac{1}{4}$

Step-by-step explanation:

We need to solve: $ln(2x)+ln(2)=0$

Solving:

$ln(2x)+ln(2)=0$

Adding -ln(2) on both sides:

$ln(2x)+ln(2)-ln(2)=0-ln(2)$

$ln(2x)=-ln(2)$

Using logarithmic rule: if $log_a b =c\,\,then\,\, b=a^c$

So,

$2x=e^{-ln(2)}$

Simplifying:

$2x=(e^{ln(2)})^{-1}\\e^{ln(2)}=2\\2x=(2)^{-1}\\2x=\frac{1}{2} \\x=\frac{1}{2x2}\\x=\frac{1}{4}$

So, Solving $ln(2x)+ln(2)=0$ we get, $x=\frac{1}{4}$

A father decided to give twenty five percent of his monthly income to his three children as their monthly allowance. The eldest

Helen [10]

Answer:

The youngest child will receive $2000

Step-by-step explanation:

A father decided to give 25% of his monthly income to his three children as their monthly allowance.

The eldest child got 45% of the allowance and the youngest got 20%. This means that the second child got:

100 - (45 + 20) = 100 - 65 = 35%

The second child received $3500.

Let the 25% of his monthly income be x.

Hence:

35% of x = 3500

=> $\frac{35}{100} * x = 3500$

$x = \frac{3500 * 100}{35}$

x = $10000

The amount the man shared among his children is $10000.

Hence, the youngest child (20%) will receive:

20% of $10000

$\frac{20}{100} * 10000$

= $2000

The youngest child will receive $2000.
