Please help?

Mazyrski [523]

Answer:

$23\sqrt{3}\ un^2$

Step-by-step explanation:

Connect points I and K, K and M, M and I.

1. Find the area of triangles IJK, KLM and MNI:

$A_{\triangle IJK}=\dfrac{1}{2}\cdot IJ\cdot JK\cdot \sin 120^{\circ}=\dfrac{1}{2}\cdot 2\cdot 3\cdot \dfrac{\sqrt{3}}{2}=\dfrac{3\sqrt{3}}{2}\ un^2\\ \\ \\A_{\triangle KLM}=\dfrac{1}{2}\cdot KL\cdot LM\cdot \sin 120^{\circ}=\dfrac{1}{2}\cdot 8\cdot 2\cdot \dfrac{\sqrt{3}}{2}=4\sqrt{3}\ un^2\\ \\ \\A_{\triangle MNI}=\dfrac{1}{2}\cdot MN\cdot NI\cdot \sin 120^{\circ}=\dfrac{1}{2}\cdot 3\cdot 8\cdot \dfrac{\sqrt{3}}{2}=6\sqrt{3}\ un^2\\ \\ \\$

2. Note that

$A_{\triangle IJK}=A_{\triangle IAK}=\dfrac{3\sqrt{3}}{2}\ un^2 \\ \\ \\A_{\triangle KLM}=A_{\triangle KAM}=4\sqrt{3}\ un^2 \\ \\ \\A_{\triangle MNI}=A_{\triangle MAI}=6\sqrt{3}\ un^2$

3. The area of hexagon IJKLMN is the sum of the area of all triangles:

$A_{IJKLMN}=2\cdot \left(\dfrac{3\sqrt{3}}{2}+4\sqrt{3}+6\sqrt{3}\right)=23\sqrt{3}\ un^2$

Another way to solve is to find the area of triangle KIM be Heorn's fomula, where all sides KI, KM and IM can be calculated using cosine theorem.

Does 1/2 and 2/7 form a proportion

barxatty [35]

Answer:

Step-by-step explanation:

Find a common denominator, and that is 14. So we convert 1/2 into 7/14 and 2/7 to 4/14, and we see it is not proportional.

An Object Speeds Up From 15 m/s to 55 m/s in only 8 s when a force of 100N Is Applied on it. What Is The Mass of the Object?

Kipish [7]

Answer:

500g

Step-by-step explanation:

Because the domula of acceleration is v-u/t so initial velocity is 15 and final velocity is 55 and mass is force * acceleration

The temperature outside was 8 degrees below zero. The next day it went up 5 degrees, followed by a decrease of 7 degrees. What i

Tatiana [17]

Hello! Your answer would be -10 degrees.

The temperature starts out eight degrees below zero. 0 - 8 = -8. Therefore, it starts off at -8 degrees.

Then, it increases by 5 degrees. Therefore, add 5 to -8. -8 + 5 = -3. Therefore, the next day has a temperature of -3 degrees.

Finally, it decreases by 7 degrees. -3 - 7 = -10. This shows us our final result - -10 degrees.

Hope this helps!
