We are given that tanx = 25.

We are also given tan(π−x).

Apply distributive rule to
tan(π−x).

tanπ − tanx

Take it from here knowing that tanx has been given to be 25.

Given tan(x)=25
we need to find tan(π-x)=cot(x) = 1/tan(x) = 1/25

Answer: tan(π-x)=1/25.

675,000 monthly salary, how much will be an hour

Ainat [17]

Answer:

So if I understood this correctly it's 675,000 a month.

675,000/30= 22500 Per day

22500/24=937.5 Per hour

Step-by-step explanation:

A monthly salary of 675,000. They want to know how much that is in an hour. So you divide 675,000 by the total number of days in a month which is 30. Then you divide that (22500) by the number of hours per day (24) and there you have it (937.5)

A rectangular parking lot has an area of 315 square yards. The width of the parking lot is 5 yards longer than the length of the

Blababa [14]

Answer:

Dimension of parking lot is approximately 15.425 × 20.425 yards.

Step-by-step explanation:

Given:

Area of the parking lot = $315 \ yd^2$

Let the length of the parking lot be $'l'$

Also Given:

The width of the parking lot is 5 yards longer than the length of the parking lot.

so we can say that;

width of the parking lot, $w=5+l$

We need to find the dimension of parking lot.

Solution:

Now we can say that;

Area of rectangle is equal to length times width.

framing in equation form we get;

$lw=315$

Now substituting the value of w in above equation we get;

$l(l+5)=315\\\\l^2+5l=315\\\\l^2+5l-315=0$

Now we will find the roots using quadratic equation.

$ax^2+bx+c =0$

a = 1

b=5

c=-315

Formula for quadratic equation is;

$l =\frac{-b\±\sqrt{b^2-4ac}}{2a}$

First we will find;

$\sqrt{b^2-4ac} = \sqrt{5^2-4\times1\times-315} =\sqrt{25+1260}=\sqrt{1285} \approx35.85$

Now we will substitute the value we get;

$l =\frac{-5\±35.85}{2\times1}= \frac{-5\±35.85}{2}$

Now we will find 2 roots we get;

$l= \frac{-5+35.85}{2}= \frac{30.85}{2}\approx15.425\\\\OR\\\\l =\frac{-5-35.85}{2}= \frac{-40.85}{2} \approx -20.425$

Now we get 2 values of length one is positive and other is negative.

But length of parking lot cannot be negative hence we will discard the negative value.

Hence the length of the parking lot = 15.425 yards

Width of the rectangular parking lot = $l+5=15.425+5 =20.425$

Hence we can say that dimension of parking lot is approximately 15.425 × 20.425 yards.

Solve the inequality and explain the stores for the two questions below:

Taya2010 [7]

Answer:

a < 3

n < 3

Step-by-step explanation:

We will solve each inequality one by one.

Solve first inequality :

3a - 4 < 5

add 4 both the side

3a < 9

divide 3 both the side

a < 3

Solve second inequality:

$\frac{n}{-3} + 5 > 4$

subtract 5 both the side

$\frac{n}{-3} > -1$

now multiply by -3 both the side and reverse the inequality sign

n < (-3)*(-1)

n < 3

That's the final answer. I hope it will help you.
