What is the slope of a line perpendicular to the line whose equation is 15x+18y=270. Fully simplify your answer.

In-s [12.5K]

Answer:

6/5

Step by step explanation:

Here we are provided with a equation which is ,

$\longrightarrow 15x + 18y = 270$

And we are interested in finding the slope of the line which is perpendicular to the given line. We may rewrite the equation as ,

$\longrightarrow 18y = -15x +270\\$

$\longrightarrow y =\dfrac{-15x+270}{18}\\$

$\longrightarrow y =\dfrac{-15}{18}x +\dfrac{270}{8}\\$

$\longrightarrow y =\dfrac{-5}{6}x +\dfrac{135}{4}$

Recall the slope intercept form of the line which is y = mx + c .On comparing to which we get ,

$\longrightarrow m =\dfrac{-5}{6}$

Again , recall that product of slopes of two perpendicular lines is -1. So that ,

$\longrightarrow m_{\perp} =-\bigg(\dfrac{1}{m}\bigg)$

Hence ,

$\longrightarrow\underline{\underline{ m_{\perp}= \dfrac{6}{5}}}$

And we are done !

A doctor raised $35,602 to use for research. She later found out that she would need $69,600 to completely pay for it all.

antoniya [11.8K]

The doctor has 35,602 and she needs 69,600.

We need to do subtraction to find out how much more she needs to raise.

69,600 - 35,602 = ?

69,600 - 35,602 = 33,998

The doctor needs to raise $33,998 more.

Your final answer is A. $33,998

Answer:

a = 15.59 c= 31.18

27 tan 30 = a

c cos 30 = 27

c = 27/cos30

c = 31.18
