Answer:

The value of x is -125

Therefore x=-125

Step-by-step explanation:

Given that the expression is $(-5)^{-3}$

To solve the expression :

$(-5)^{-3}$

$=\frac{1}{(-5)^3}$ ( by using the property $a^{-m}=\frac{1}{a^m}$ )

$=\frac{1}{(-5)\times (-5)\times (-5)}$ ( expanding the power )

Let $x=(-5)\times (-5)\times (-5)$

$=\frac{1}{x}$

Now the value of x is $x=(-5)\times (-5)\times (-5)$

$=-125$

Therefore x=-125

The value of x is -125

What is minimal completion time for the activities in the graph below? In a complete sentence, explain how you got your answer

kupik [55]

The minimal completion time for the activities is the shortest possible time for all the activities to be finished. In doing this, we look at the path that would require the greatest amount of time. At the START node, we choose the path that would take the longest which is 7 days leading to ACTIVITY D. Next, we choose the path leading to ACTIVITY B which takes 5 days. Then, we move to ACTIVITY C taking 5 days and finally, reach the END which would take 6 days. So, the minimal completion time is:
7 + 5 + 5 + 6 = 23 days

AveGali [126]

Answer: The standard deviation formula may look confusing, but it will make sense after we break it down. ...

Step 1: Find the mean.

Step 2: For each data point, find the square of its distance to the mean.

Step 3: Sum the values from Step 2.

Step 4: Divide by the number of data points.

Step 5: Take the square root.

Please help me thank you

Question 1:

We have a 45-45-90 right triangle with the hypotenuse being the length from one corner to the opposite corner.

Multiply 30 ft with the square root of 2 and use a calculator to help give you numerical value to get your answer.

$30 \sqrt{2} \approx 42$

Your answer is the second choice.

Question 2:

The equilateral triangle can be divided into 2 30-60-90 triangles with the longer leg being the altitude. To get half of the side length of the right triangle, divide the altitude by the square root of 3.

$\dfrac{15}{ \sqrt{3} }=\dfrac{15 \sqrt{3} }{3}=5 \sqrt{3}$

The full side length is double of that, which is $10 \sqrt {3}$ .

Multiply that by 3 to get the full perimeter.
$10 \sqrt{3}*3=30 \sqrt{3}$

Your answer is the third choice. Hope this helps! :)
