Please help! -3n+147=0

Mathematics
1 answer:
horrorfan [7]3 years ago
6 0

Answer:

n = ±7

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

<u>Algebra I</u>

  • Solving quadratics

Step-by-step explanation:

<u>Step 1: Define equation</u>

-3n² + 147 = 0

<u>Step 2: Solve for </u><em><u>n</u></em>

  1. Subtract 147 on both sides:                    -3n² = -147
  2. Divide -3 on both sides:                          n² = 49
  3. Square root both sides:                           n = ±7

What is tan(x)-5=0<br> (With steps)
gizmo_the_mogwai [7]
\tan x-5=0
\tan x=5

Now before taking the inverse tangent of both sides, recall that

\tan x=\tan(x\pm\pi)=\tan(x\pm2\pi)=\cdots=\tan(x\pm n\pi)

where n is any integer. This means that when taking the inverse tangent of \tan x, instead of just x, we would end up with

\arctan(\tan x)=\arctan(\tan(x+n\pi))=x\pm n\pi

So after doing so in the equation above, we're left with

x\pm n\pi=\arctan5\implies x=\arctan5\pm n\pi

As n can be any integer, including negative integers, we can simply write

x=\arctan5+n\pi,\,n\in\mathbb Z

Water flowed out of a tank at a steady rate. A total of 18 1/2 gallons flowed out of the tank in 4 1/4 hours. Which expression
Alecsey [184]

Answer:

In 1 hour water flowed out = \frac{74}{17}  gallons

Step-by-step explanation:

Given as ,

The quantity of water flowed out of tank =  18 \frac{1}{2} gallons

                                                                   =    \frac{37}{2} gallons

The time spend in flowing water out of tank = 4  \frac{1}{4} hours

                                                                          =    \frac{17}{4} hours

∵ In  \frac{17}{4} hours , water flowed out =  \frac{37}{2}

∴ In    1    hours                           ,  water flowed out = \frac{37\times4}          {17\times2}

So, in 1 hour water flowed out = \frac{74}{17}  gallons Answer

Eduardwww [97]
Hello There!

You divide 43 by 4:
43/4 = 10.75
It isn't a whole number.
Therefore, each employee would do approximately 11. 
However, the exact amount is 10.75

Hope This Helps You!
Good Luck :)
