1km=1000m = 100000cm

It is known that 1 m is equal to 100 cm and that 1 km is also equal to 1000 m. Thus, the conversion may be done by the dimensional analysis and the use of proper conversion factors. 
                   (86000 cm) x (1 m/ 100 cm) x (1 km / 1000 m) = 0.86 km
Therefore, the answer is 0.86 km.

Find the value of x using the diagram below. Round to the nearest whole number. Picture Attached.
VashaNatasha [74]
Both triangles are right triangles. x is the hypotenuse of the upper one. ThePythagorean formula  will give the value of x. One side is known, The other side we will find using the fact that the lower right triangle is isosceles. The hypotenuse of an isosceles right triangle has a length of \sqrt{2} times the length of one of the legs. In this case 14. So the hypotenuse of the lower triangle is also the short side of the upper triangle. Using Pythagoras

25^{2} +  (14 \sqrt{2}) ^{2} = x^{2}

625 + 392 =  x^{2}

 1017 =  x^{2}

32 = x

Solution -9-8(1+4h)= -17
geniusboy [140]
Step 1. <span>Add </span>9<span> to both sides

</span>-8(1+4h)=-17+9

Step 2. Simplify -17+9 to -8

-8(1+4h)=-8

Step 3. Divide both sides by -8

1+4h=1

Step 4. Cancel 1 on both sides

4h=0
 Step 5. Divide both sides by 4

h=0

Done! :) Hope this helps! :)

To check -9-8(1+4h)=-17 follow these steps below:

Step 1. Let h = 0

-9-8*(1+4*0)=-17

Step 2. Simplify 4 * 0 to 0

-9-8*(1+0)=-17

Step 3. Simplify 1 + 0 to 1

-9-8*1=-17
<span>
Step 4. </span><span>Simplify  8 * 1 to 8
</span>
-9-8=-17
<span>
Step 5. </span><span>Simplify -9 -8 to -17
</span><span>
</span>-17=-17
