Answer:

99inches

Step-by-step explanation:

The ratio of the sides of a triangle =2:4:9.

perimeter = 165 inches,

Total ratio= 2+4+9=15

perimeter = 165

Divide the perimeter by total ratio

165/15=11

Each of the sides

= (2×11) =22

(4×11) =44

(9×11)=99

the length of the longest side= 99inches

I need to find the equation of the line. Can someone please help?

NikAS [45]

The formula is y = mx + b when b = y-intercept and m is the slope.

Slope = Rise/Run So 1/2.

Y-Int. = The y value at which x = 0. Which is -3

The line has the formula:

Y = 1/2x - 3

Hope this helps :)

$\dfrac{\sin\theta\cdot\cot\theta}{\tan\theta\cdot\cos\theta}=\dfrac{\sin\theta}{\cos\theta}\cdot\dfrac{1}{\tan\theta}\cdot\cot\theta=\tan\theta\cdot\dfrac{1}{\tan\theta}\cdot\cot\theta=\boxed{\cot\theta}$

$\dfrac{\cot\theta}{\cos\theta}\cdot\dfrac{\sin\theta\cdot\cos^2\theta}{1-\cos^2\theta}=\dfrac{\cot\theta}{\cos\theta}\cdot\dfrac{\sin\theta\cdot\cos^2\theta}{\sin^2\theta}=\cot\theta\cdot\dfrac{\cos\theta}{\sin\theta}=\cot\theta\cdot\cot\theta=\\\\\\=\boxed{\cot^2\theta}$

You spent $10 on office supplies out of a $25 budget. What percentage did you spend

Alexxandr [17]

The simplest way to find percent is to take the partial number, divide by the whole number, and multiply the answer by 100%.

= 0.4

0.4 x 100% = 40%.
