Answer:

B. 9,000,000,000

Step-by-step explanation:

From the given information:

We are to determine the best estimate of the number of bottles sold this year and last year.

The best estimate means rounding up to the nearest whole number.

Given that:

7,234,267,990 bottles of water were purchased this year

2,000,900,999  bottles of water were purchased last year

The estimate of the bottles sold this year and last year from the above value is:

= 7,000,000,000 + 2,000,000,000

= 9,000,000,000

In ABC, what is the value of x?<br><br> Pls hurry im on a time limit here
kiruha [24]

Answer:

70

Step-by-step explanation:

By exterior angle theorem:

(2x + 12) \degree = 112 \degree + 180 \degree - 2x \degree \\  \\ (2x + 12) \degree = 292 \degree - 2x \degree \\  \\ (2x + 12) \degree  + 2x \degree = 292 \degree \\  \\ (2x + 12 + 2x) \degree = 292 \degree \\  \\ (4x + 12) \degree = 292 \degree \\  \\ 4x + 12  = 292  \\  \\ 4x = 292 - 12 \\  \\ 4x = 280 \\  \\ x =  \frac{280}{4}  \\  \\ x = 70

A card is drawn from a standard deck of 5252 playing cards. What is the probability that the card will be a heart or a face card
mr_godi [17]

Answer:

The probability that the card will be a heart or a face card is P=0.4231.

Step-by-step explanation:

We have a standard deck of 52 cards.

In this deck, we have 13 cards that are a heart.

We also have a total of 12 face cards (4 per each suit). So there are 3 face cards that are also a heart.

To calculate the probability that a card be a heart or a face card, we sum the probability of a card being a heart and the probability of it being a face card, and substract the probability of being a heart AND a face card.

We can express that as:

P(H\,or\,F)=P(H)+P(F)-P(H\&F)\\\\P(H\,or\,F)=13/52+12/52-3/52=22/52=0.4231

Find f(x) if g(f(x))=x and g(x)=(x+1)/(x-1)​
Firdavs [7]

Answer:

  f(x) = (x +1)/(x -1)

Step-by-step explanation:

Let f(x) = y. We want to find y such that ...

  g(y) = x

  (y +1)/(y -1) = x

  y +1 = xy -x . . . . . . multiply by y-1

  y -xy = -x -1 . . . . . . add -1 -xy

  y(x -1) = x +1 . . . . . . multiply by -1 and factor out y

  y = (x +1)/(x -1) . . . . divide by the coefficient of y

Then ...

  f(x) = (x +1)/(x -1)

_____

<em>Check</em>

  g(f(x)) = ((x +1)/(x -1) +1)/((x +1)/(x -1) -1)

  = ((x +1 +x -1)/(x -1)) / ((x +1 -x +1)/(x -1))

  = 2x/2

  = x
