Area of trapezoid = 1/2 (sum of parallel sides) × (perpendicular distance between them)

Area = 1/2 × (3 + 7) × 2 = 10 ft²

So we will be using dimensional analysis to solve it as such:

$\frac{23843\ kL}{1}*\frac{1000\ L}{1\ kL}*\frac{1\ Gal}{3.79\ L}=\frac{23843000}{3.79}=6291029.02\ Gallons$

In short, 23,843 kL is 6,291,029.02 (6,291,029 rounded to the whole gallon) gallons.

Kali had a total of 212121 balloons at her birthday party. The ratio of blue balloons to green balloons is shown in the tape dia

Misha Larkins [42]

Answer:

Blue balloons = 12

Step-by-step explanation:

Total no of balloons = 21

Let us assume that the ratio of blue balloons to green balloons is 4:3.

Let there are 4x blue balloons and 3x green balloons.

ATQ,

4x+3x = 21

7x = 21

x = 3

Blue balloons = 4x

= 4(3)

= 12

Hence, she will have 12 blue balloons at her party.

Why are angles opposite each other when two lines cross called vertical angles?

Nezavi [6.7K]

They are called vertical angles because the definition of vertical is: <span>in a direction, or having an alignment, such that the top is directly above the bottom. The "angles opposite each other when two lines cross" match the definition.</span>

Score Frequency

RUDIKE [14]

Scores on an AP Exam at a local high school are recorded in the table. What was the average score?

Answer: D) 4.266 is correct

Explanation:

We are given the below frequency table:

Score Frequency

1 | 0

2 | 3

3 | 4

4 | 16

5 | 22

Let's denote the score by $x$ and frequency by $f$ .

The average formula is:

$Average=\frac{\sum fx}{\sum f}$

$=\frac{(1\times0) + (2\times3)+(3\times4) +(4\times16) + (5\times22)}{0+3+4+16+22}$

$=\frac{0+6+12+64+110}{45}$

$=\frac{192}{45}=4.267$

Therefore, the average score was 4.267

Hence the option D) 4.266
