NNADVOKAT [17]
Simplify the denominator so it is the same 
divide the 4 by 2
4 divided by 2=2 
now the denominator the same.
16 1/2
2 3/2 
multiply 3x1
so far, it is 3/2
it is an improper fraction
divide.
2 divides by 3 = 0.1 i know
1/2
Hope this helped :D! can you mark me brainliest...

Sever21 [200]

Answer:

D)$732.84

Step-by-step explanation:

A=p(1+r/n)^nt

P=principal=$600

r=5%=0.05

t=4 years

n=12 months

A=p(1+r/n)^nt

=600(1+0.05/12)^12*4

=600(1+0.0041666666666 )^48

=600(1.0041666666666 )^48

=600( 1.2208953550215 )

=732.53

A=$732.53

Option D)$732.84 is the answer

Answer:

More clarification

Step-by-step explanation:

2 of a white ball =2/30 =1/15;

This is the probability of picking a black ball.

Let the number of black ball be X

x/(x +20)= 1/15[ probability of picking black ball ]

15x = x + 20 ; by cross multiplication

14x=20; x = 20/ 14 =1.42 = 1 [ approximately]

But to satisfy the premise given above; we have to approximate the no of balls to 2

The point P(8, −3) lies on the curve y = 3/(7 − x). (a) If Q is the point (x, 3/(7 − x)), use your calculator to find the slope
yan [13]

Answer:

Slope of the line PQ is -63.434948.

Step-by-step explanation:

Given that,

The point P(8,-3) lies on the curve y=\frac{3}{7-x}.

If Q is the point lies on (x,\frac{3}{7-x} ).

To find:- Find the slope of line PQ.

So,  

The coordinates of point Q when it lies on (x,\frac{3}{7-x} )

        if x=1 then y= \frac{3}{7-1} =\frac{3}{6} =\frac{1}{2}

       So,   Q ≡ (1,\frac{1}{2} ) and many points can be calculated by given Equation.

Using the formula when two points (x_{1} ,y_{1} ) \& (x_{2}, y_{2}  ).

                Slope=Tan\theta = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

Then, substituting the coordinates we get,

             Slope = \frac{1-8}{\frac{1}{2}-(-3) }

             Slope = \frac{-7}{\frac{1}{2}+3 } = \frac{-7}{\frac{7}{2} }

             Slope = \frac{-14}{7}=-2

              tan\theta=-2   ⇒  \theta = tan^{-1} (-2)

               \theta= -63.434948

Therefore,

Slope of the line mPQ is -63.434948.
