3) 6 x 3 = 18 + 1/2 x 12 x 15 = 90 = 90+ 18 = 108ft^2

4) = 12 x 12 = 144 + 4x4 = 16 +12 x 4 = 48 = 144+12+48 = 204m^2

5) = 8 x 12 = 96 + 1/2 x 4 x 6 = 12 = 108ft^2

6) = 3x 3 = 9 + pi3^2 = 28.2743339 (x2) =56.5486678 + 9 = 65.5m^2

proves 4 semi circles = 2 circles

7) 10 x 8 = 80 +4 x 4 = 16 + 1/2 x 2 x 4 = 4 = 20+80= 100ft^2

proves 14-8-4 = 2ft is the triangle length and 10-6 = 4 the triangle height.

8) 4x6 = 24 + 1/2 x 4 x 2 = 4 + pi 4^2 = 1/2 x 50.2654825 = 24+4 + 25.1329 = 53.1m^2

If something cost $37.80, how many tens would you give?

Sophie [7]

Answer:

4 tens

Step-by-step explanation:

3 tens would get you $30, which is $7.80 short. If you give 4 tens you are giving $40 which is 2.20 more than $37.80, which is okay as you can probably get change and it is the least amount of tens you can give to cover the cost.

Steam and leaf plot help!!!! picture down below

Diano4ka-milaya [45]

I would say that the correct answer is C because if you look up on the chart thing, it tells you how you would see the graph. For example, when you have:

1| 03145
2| 4 6 3 7

Which one has the most value to it? It would be the 2| 4 6 3 7, because when you put them together, it makes 24, 26, 23, 27. Hope this helps.

A geologist examines 6 seawater samples for lead concentration. The mean lead concentration for the sample data is 0.903 cc/cubi

Gnesinka [82]

Answer:

Step-by-step explanation:

We want to determine a 95% confidence interval for the mean lead concentration of sea water samples

Number of samples. n = 6

Mean, u = 0.903 cc/cubic meter

Standard deviation, s = 0.0566

For a confidence level of 95%, the corresponding z value is 1.96. This is determined from the normal distribution table.

We will apply the formula

Confidence interval

= mean +/- z ×standard deviation/√n

It becomes

0.903 +/- 1.96 × 0.0566/√6

= 0.903 +/- 1.96 × 0.0566/2.44948974278

= 0.903 +/- 0.045

The lower end of the confidence interval is 0.903 - 0.045 =0.858

The upper end of the confidence interval is 0.903 + 0.045 =0.948

Therefore, with 95% confidence interval, the mean lead concentration of the sea water is between 0.858 cc/cubic meter and 0.948 cc/cubic meter
