Answer:

If this is a normal triangle, it is impossible to solve for unique x.

However, if this is a right triangle with hypotenuse = 40 ft as shown in picture, then, by applying Pythagorean theorem, we have:

(3x)^2 + (6x)^2 = 40^2

<=> 9x^2 + 36x^2 =40^2

<=> 45x^2 =40^2

<=> x^2 = (40/45)^2

<=> x = 40/45

And the two side lengths would be :

6 x 40/45 = 6 x 8/9 = 48/9 = 16/3 = 5.3 ft

3 x 40/45 = 3 x 8/9 = 24/9 = 8/3 = 2.7 ft

Hope this helps!

Answer:

x = 35.6

3x = 106.7

6x = 213.3

Step-by-step explanation:

Using pythagoras theorem

(6x)² + (3x)² = 40²

36x² + 9x² = 1600

45x² = 1600

x² = 320/9

x = 35.555555

3x = 106.66666

6x = 213.3333

Which measure of central tendency is the most affected by outliers
aliina [53]

Mean measure of central tendency is the most affected by outliers. Then the correct option is B.

<h3>What is Mean?</h3>

The mean is the straightforward meaning of the normal of a lot of numbers. In measurements, one of the markers of focal propensity is the mean. The normal is alluded to as the number-crunching mean. It's the proportion of the number of genuine perceptions to the absolute number of perceptions.

Mean measure of central tendency is the most affected by outliers.

Then the correct option is B.

More about the mean link is given below.

If two triangles have three corresponding angles and three corresponding sides that are equal in measure, are the two triangles
nikitadnepr [17]
Yes, they are.

If the triangles have three corresponding angles equal means that they are either similar or congruent.

The definition of congruent means that the sides have the same length. That is precisely what the statement says.

So, being the lengths of the corresponding angles the same the two triangles are identical, this is they are congruent.

Kerrie uses the work shown below to determine 35% of 280.
lys-0071 [83]

For this case we must find 35% of 280.

Kerrie gets 10% and then 25%. So:

10% of 280:

280 ------------> 100%

x -----------------> 10%

Where "x" represents the amount given by 10% of 280.

x = \frac {10 * 280} {100}\\x = 28

Thus, 10% of 280 is 28.

Now, we find 25% of 280:

280 ------------> 100%

x -----------------> 25%

Where "x" represents the amount given by 25% of 280.

x = \frac {25 * 280} {100}\\x = 70

Thus, 25% of 280 is 70.

So we have that 35% of 280 is given by:

28 + 70 = 98

So, Kerrie's solution is correct.

Option A
