Answer

Step-by-step explanation:

so, this triangle is an "impossible' triangle, b/c  even when the 5 and 4 sides are laid out, in opposite directions, they only make a distance of 9. so the side of 12 is not ever going to work in this triangle, it's just too long.  so the answer is none of the choices are correct.  To be fair, this question is incorrect.  The picture that is drawn, makes it look like the triangle could be real. when it's not.  like an Escher drawing. if  you don't know Escher drawings look  them up

-\frac{1}{3}\left|1\cdot \left(\frac{1}{2}\right)^2\right|-\frac{2}{3}-2^3-\frac{2}{3}\left|-\frac{1}{2}\right|^3
\frac{1}{3}\left|1\cdot \left(\frac{1}{2}\right)^2\right|=\frac{1}{12}
\frac{2}{3}\left|-\frac{1}{2}\right|^3=\frac{1}{12}

The average number of newspapers for sale in an airport stand is 15. SD is 6. The average age of the pilots is 36 and SD is 4. W
balu736 [363]

Answer:

The average age of pilots has a lower coefficient of variation, so it is the most consistent data set.

Step-by-step explanation:

The coefficient of variation is used to measure consistency of a data set. It is the standard deviation divided by the mean. The higher the coefficient of variation, the more variable, that is, the least consistent the data set is.

The average number of newspapers for sale in an airport stand is 15. SD is 6.

The consistency is:

C = \frac{6}{15} = 0.4

The average age of the pilots is 36 and SD is 4.

The consistency is:

C = \frac{4}{36} = 0.11

The average age of pilots has a lower coefficient of variation, so it is the most consistent data set.

Factor each completely. <br><br>10a² - 9a + 2 <br><br>​
Sophie [7]

Answer:

a= \frac{2}{5} or \frac{1}{2}

Step-by-step explanation:

Equate the equation to zero

10a^{2}-9a+2=0

10a^{2}-5a-4a+2=0

5a(2a-1)-2(2a-1)=0

Write out the factors

(5a-2)(2a-1)=0

Then equate each factor to zero

5a-2=0 OR 2a-1=0

5a=2  OR  2a=1

a= \frac{2}{5}   OR a= \frac{1}{2}

a=\frac{2}{5} or \frac{1}{2}

6.5 kg to 3.9 kg, what was the percent decrease
igomit [66]

Answer: 40%

Step-by-step explanation:

Given,

Initial mass = 6.5kg

final mass = 3.9kg

So, Change in mass = initial mass - final mass

                                  = 6.5 - 3.9

                                  = 2.6 kg

and,

Change in percentage of mass = \frac{change in mass}{original mass} * 100

Change in percentage of mass = \frac{2.6}{6.5} * 100

                                                    = 40

Find the surface area of each figure. Round to the nearest 10th
AnnZ [28]

Answer:

The surface area of the figure is 352 cm².

Step-by-step explanation:

Given:

Length(l) = 12 cm.

Width(w) = 4 cm.

Height(h) = 8 cm.

Now, to find the surface area.

By putting the formula to get the surface area:

Surface area = 2(l×w+w×h+h×l)

Surface\ area =2(12\times 4+4\times 8+8\times 12)

Surface\ area =2(48+32+96)

Surface\ area =2\times 176

Surface\ area =352 cm^2.

Therefore, the surface area of the figure is 352 cm².
