Which measurement is greatest? 6 kilometers, 60 meters,600 centimeters, 6000 millimeters

Rashid [163]

Convert all of them to meters.

1 km = 1000 meters

6 * 1000 = 6000

6 km = 6000 m

1 cm = 0.01 m

600 * 0.01 = 6

600 cm = 6 m

1 mm = 0.001 m

6000 * 0.001 = 6 m

So we have:

6000 m, 60 m, 6 m, and 6 m.

So 6 kilometers is the greatest.

Find the area of the trapezoid!!!! PLEASE HELP!!!!

san4es73 [151]

ANSWER

$32 \sqrt{3} {ft}^{2}$

EXPLANATION

The area of a tra-pezoid is half times sum of the bases times the vertical height.

From the diagram ( see attachment) we use the Pythagoras Theorem to obtain,

${x}^{2} + {(4 \sqrt{3}) }^{2} = {8}^{2}$

${x}^{2} + 48 = 64$

${x}^{2} = 64 - 48$

${x}^{2}=16$

$x = \sqrt{16} = 4ft$

This implies that , y=10-4=6ft

The area of tra-pezoid

$= \frac{1}{2} (10 + 6) \times 4 \sqrt{3}$

$= \frac{1}{2} (16) \times 4 \sqrt{3}$

$= 8\times 4 \sqrt{3}$

$= 32 \sqrt{3} {ft}^{2}$
