Given:

A right angled triangle.

To find:

The value of x.

Solution:

We have,

Base = x

Hypotenuse = $\sqrt{5}$

In a right angle triangle,

$\cos \theta = \dfrac{Base}{Hypotenuse}$

For the given triangle,

$\cos 45^\circ= \dfrac{x}{\sqrt{5}}$

$\dfrac{1}{\sqrt{2}}= \dfrac{x}{\sqrt{5}}$

Multiply both sides by $\sqrt{5}$ .

$\dfrac{\sqrt{5}}{\sqrt{2}}= x$

$\dfrac{\sqrt{5}}{\sqrt{2}}\times \dfrac{\sqrt{2}}{\sqrt{2}}= x$

$\dfrac{\sqrt{10}}{2}= x$

Therefore, the required value of x is $\dfrac{\sqrt{10}}{2}$ .

Jose invested $5000 into a fund with an interest rate of 4.8%. How much interest would he earn after 2 years? A) $240 B) $24,000

pogonyaev

Answer: C) $480

Step-by-step explanation:

Given: Jose invested $5000 into a fund with an interest rate of 4.8%.

Therefore, Principal amount (P)$5000

Rate of interest = 4.8%

In decimal rate of interest(r)=0.048

Time (t)= 2 years

We know that the simple interest is given by

$S.I.=Prt\\\Rightarrow\ S.I.=5000\times0.048\times2\\\Rightarrow\ S.I.=\$480$

Hence, the interest after 2 years = $480

A man's salary is increased by $925 to $1036. Find the percentage increase. What would have been his new salary if the increase

exis [7]

Answer:

See the solutions below

Step-by-step explanation:

Initial Salary= $925

Final salary= $1036

% increase= Change/initial *100

substitute

% increase= 1036-925/925 *100

% increase=111/925 *100

% increase=0.12 *100

% increase=12%

2. Let us find 16% of $925

=16/100*925

=0.16*925

=$148

Hence the salary would have been

=148+925

=$1073
