This year consumers purchased 7,234,267,990 bottles of water. Last year consumers purchased 2,000,900,999 bottles of water. Whic

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

Evaluating the options :

Option 1

2 |x - 5| - 4 < -8
2 |x - 5| < -4
|x - 5| < -2
Empty set as modulus cannot be less than 0

Option 2

|2x - 1| - 7 < -6
|2x - 1| < 1
x < 1
There is a solution set other than empty set

Option 2 is the right answer.

Pentagon TEXAS has vertices at T(1, 8), E(3, 8), X(6, 2), A(3, 2), and S(1, 4). What is the area of Pentagon TEXAS?

Tamiku [17]

The area of the pentagon is 19 square units

The coordinates of the pentagon are given as:

$T = (1, 8)$

$E =(3, 8)$

$X =(6, 2)$

$A=(3, 2)$

$S = (1, 4)$

The area of the pentagon is then calculated using:

$Area = \frac 12|(x_1y_2+x_2y_3+x_3y_4+x_4y_5+x_5y_1) -(y_1x_2+y_2x_3+y_3x_4+y_4x_5+y_5x_1)|$

So, we have:

$Area = \frac 12|(1 \times 8 +3 \times 2+6\times2+3 \times 4 + 1 \times 8) -(8\times3+8\times6+2\times3+2\times1+4\times1)|$

Simplify the expressions in both brackets

$Area = \frac 12|46 -84|$

$Area = \frac 12|-38|$

Remove absolute bracket

$Area = \frac 12 \times 38$

$Area = 19$

Hence, the area of the pentagon is 19 square units
