Use one unit multiplier to convert 5,000 meters to centimeters
wel

Answer:

5000 meters = 5000 × 100 = 500000 centimeters.

Conversion of 5000 meters to other length, height & distance units

5000 meters = 5 kilometers

5000 meters = 50000 decimeters

5000 meters = 5000000 millimeters

5000 meters = 5 × 1013 angstroms

5000 meters = 3.11 miles

5000 meters = 2730 fathoms

5000 meters = 5470 yards

5000 meters = 16400 feet

5000 meters = 49200 hands

5000 meters = 197000 inches

5000 meters = 43700 fingers

5000 meters = 1562 1

Shelia mixed 3 ounces of blue paint with 2 ounces of yellow paint. She decided to create 20 ounces of the same mixture. How many
zimovet [89]
Yellow:blue is a ratio of 2:3, meaning that 2/5 of the desired mixture is yellow. From this, you need to find how much yellow is necessary for 20 ounces. Well, 2/5 of the 20 ounces will be yellow paint, while the other 3/5 will be blue. So she will need 8 ounces of yellow paint to get 20 ounces of the desired mixture. Hope this helps! :)

If g=27 and f=54degrees, find h on a triangle. a. h=15.9. b. =14.9. c. 16.9. d. 18.9
sattari [20]
I assume h is the hypotenuse on a triangle. We use trigonometric functions in order to find the value of h. Also, since side g is not specified whether it is adjacent or opposite angle f. We solve using every possible function and see from the choices the correct answer.

h = 27 sin 54 = 21.84
h = 27 cos 54 = 15.9

Therefore, most likely the correct answer is A.
