7 0
Lateral surface are = 2( 1/2 x 11 x 11.9) + 2( 1/2 x 9 x 12.3)

Lateral surface area = 130.9 + 110.7 = 241.6 ft²

Answer: 241.6 ft² (Answer C)

Determine the equation of the inverse of y=-4/x+1 The inverse is y=-a/x-b where a = a0 and b = a1
leva [86]
<span>y=-4/x+1 is ambiguous, since it's not immediately clear whether you meant 

                                                -4
y = -4/x   +    1      or      y = ---------
                                               x+1

I'm going to assume that the latter is what you meant.

1.  Interchange x and y, obtaining:

               -4
     x = --------
             y+1

2.  Solve this for y, obtaining  y+1 = -4/x, or   xy + x = -4, or
                                
                                -x - 4
    xy = -x-4, or y = ---------
                                    x

                                   -1              -1                 4
3.  Replace y with    f      (x):      f    (x) = -1 - -----
                                                                         x

This last result has the correct form.</span>

A bag contains n blue and m red marbles. You randomly pick a marble from the bag, write down its color, and then put the marble
Oksana_A [137]

Answer:

(mn+n²)/(m+n)

Step-by-step explanation:

probability of blue marble= n/(n+m)

probability of red marble= m/(n+m)

probability that process stops = Probability of both blue + probability of both red=  n/(n+m) × n/(n+m) + m/(n+m)×m/(n+m)

                        = (n²+m²)/(n+m)²

P(1st marbel is blue)= P(blue and red) + P(blue and blue)

                                  = mn/(n+m) + n²/(n+m)

                                   = (mn+n²)/(m+n)

P(1st marble is blue | process stops)= ( (mn+n²)/(m+n)× (n²+m²)/(n+m)²)/ ((n²+m²)/(n+m)²)

= (mn+n²)/(m+n)

SOMEBODYY HELP ILL GIVE BRAINLYY......
ANTONII [103]

Step-by-step explanation:

a^2+b^2 = c^2

C is the biggest number, so put in all the numbers in the equation then if it's equal then it's a right triangle.

example: 6^2 + 8^2 = 10^2

36 + 64 = 100

100 = 100

this one is a right angle because the two sides is equal to the hypotenuse(largest number).
