What is 80% of 400? show work

Answers

80% of 400

We can set up a proportion because it makes things more clear. 

First, we need to assume that 400 is our '100'. Usually, 100 is our total value. 

400/x=100/80
(400/x)*x=(100/80)*x       
400=1.25x        
400/1.25=x 
320=x 
x=320

Our final answer: 320

of in mathematics means multiplication

80% = 80/100 = 0.8

0.8 * 400 = \boxed{320}

80% of 400 is 320.

What is the domain of the function y=ln(12-4x/5)

Answers

Answer:

The domain of the function is  x<3                                

Step-by-step explanation:

Given : Function y=\ln ((12-4x)/(5))

To find : What is the domain of the function ?

Solution :

Domain is defined as the set of possible values which define the function.

We know that, log negative is not defined.

So, we will get the inequality  in the function.

\ln ((12-4x)/(5))>0

(12-4x)/(5)>0

12-4x>0

-4x>-12

x<3

Therefore, The domain of the function is  x<3

\ln x has a domain of x>0, so \ln\left(12-\frac{4x}5\right) has a domain of

12-\frac{4x}5>0\implies12>\frac{4x}5\implies x<15

bob eats 6 apples in 2 days. how many days will it takes to eat a basket of apples containing 51 apples?

Answers

if he eat 6 apples in 2 days so we can say he eat 3 apple in 1 day so if we want to know in how many days he can eat 51 apple you can say 51 ÷ 3= 17 also we can say 1day / 3 apples = ? days / 51 apples ⇒ 51×1 / 3 = 17 so he can eat 51 apples in 17 days :))))
i hope this be helpful 
* happy new year * 
51/6=8.58.5*2=17It would take 17 days for Bob to eat a basket of apples containing 51 apples.

J is a trapezium/trapezoid.
The picture i have attached may help you more.
J is a right trapezoid.  It is a right trapezoid because it has a 90 degree,  or right,  angle.  That is the angle that makes a perpendicular,  or square-like,  shape if it were to intersect with another line.

OK.  These problems are easy if you know the quadratic formula,
and they're impossible if you don't.

Here's the quadratic formula:

When the equation is in the form of      Ax² + Bx + C = 0

then                    x =  [ -B plus or minus √(B²-4AC) ] / 2A

I'm sure that formula is in your text or your study notes,
right before these questions.  You should cut it out or
copy it, and tape it inside the cover of your notebook.
Then, you'll always have it when you need it, until
you have it memorized and can rattle it off.

The first question says        3x²  +  5x  +  2  = 0

Is this in the form of             Ax²  +  Bx  +  C  = 0    ?

             Yes !                    A=3      B=5   C=2

             so you can use the quadratic formula to solve it.

            x =  [ -B plus or minus √(B²-4AC) ] / 2A

               =  [ -5 plus or minus √(5² - 4·3·2) ] / 2·3

               =  [ -5 plus or minus √(25 - 24)  ]  /  6

               =  [  -5 plus or minus  √1          ]  /  6

           =        -4 / 6  =  -2/3
and
           =        -6 / 6  =  -1 .    
_______________________________________

The second question says

                                         4x²  +  5x  -  1 = 0

Is this in the form of          Ax²  +  Bx + C = 0  ?

           Yes it is !            A=4     B=5   C= -1  

         so you can use the quadratic formula to solve it.

            x =  [ -B plus or minus √(B²-4AC) ] / 2A

Now, you take it from here.
