The answer is 16m² because the square root of 81 is 9 meaning both width and height of the patio are 9. to find the height of the square patch you do 9 - 5 = 4
because it is square, meaning the width and height are the same, so therefore the width is also 4. to get the area of a square of rectangle, you times the width by the height. 4 × 4 = 16. so the answer is 16m² because the unit is metre so we write m²

Graph the solution of the inequality: 3/7 (35x-14) ≤ 21x/2 + 3

hammer [34]

Hello there!

In order to graph the solution, we need to solve it first.

So let's start....

3/7(35x - 14) ≤ 21x/2 + 3

15x -6 ≤ 21x/2 + 3

15x - 21x/2 ≤ 3 + 6

9x/2 ≤ 9

x ≤ 9* 2/9

x ≤ 18/9

x ≤ 2

See the picture for the graph

Please let me know if you have questions about the answer.

Thanks!

Assuming a 90% confidence level, the margin of error is approximately?

elena-s [515]

Answer:

0.3

Step-by-step explanation:

The margin of error is calculated as ...

(standard deviation)/√(sample size) × (z*-score)

where the z*-score is chosen based on the desired confidence level.

Here, you have ...

standard deviation = 2.7
√(sample size) = √225 = 15
z*-score for 90% confidence level = 1.645

Putting these values in the above expression for margin of error gives ...

2.7/15·1.645 = 0.2961 ≈ 0.3

Sage has 3 strip-mats, 3 mats, and 2 units. Tristan has 2 mats, 8 strips, and 5 units. Andre had twice as many strip-mats, mats,

sladkih [1.3K]

The question is an illustration of equivalent equations.

<em>There are 11 units in all</em>

The given parameters are:

<u>Sage</u>

$\mathbf{Strip-mat = 3}$

$\mathbf{Mat = 3}$

$\mathbf{Units = 2}$

<u>Tristan</u>

$\mathbf{Strip-mat = 8}$

$\mathbf{Mat = 2}$

$\mathbf{Units = 5}$

Andre has twice of what Sage has

So, the total unit is:

$\mathbf{Total = Sage + Tristan + Andre}$

<em>Sage has 2 units</em>

<em>Tristan has 5 units</em>

<em />

Because, Andre has twice of what <em>Sage has,</em>

Andre's number of units would be 4

So, we have:

$\mathbf{Total = 2 +5 + 4}$

$\mathbf{Total = 11}$

Hence, there are 11 units in all
