- <em>You would need fewer the unit</em><em><u> </u></em><u>kilometer (km) </u><em>to measure a tree.</em>
Explanation:
In the internet you can find that the greatest height of a tree is aobut 115 meters.
Thus, you would never expect to find a tree measuring kilometers or miles.
If you used kilometers as unit, the measure of the tallest tree woul be about 0.115 km (115 meter divided by 1,000).
Most of the trees meausre in the range of 1 to 20 meters. That would be 0.001 km to 0.020 km.
Thus, kilometer is not a unit that you would need to measure a tree. You'd rather use centimeters, when the tree is small, and meters for most of the trees. You may also use feet, since 1 meter is about 3.28 feet, or even yards, since 1 yard is equal to 3 feet.
Answer:
The second set of equations is the one you want.
Step-by-step explanation:
If s is the cost of a shirt and you buy 3 of them, you represent that as 3s. Likewise with all the other numbers of articles of clothing you are given. The first situation then is 3s + 5t = 60. The second situation is 2s + 3t = 39.
Answer:
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this problem:
20 numbers
Multiple of 3:
3,6,9,12,15,18
Greater than 10:
11,12,13,14,15,16,17,18,19,20
Multiple of 3 or greater than 10:
3,6,9, 11,12,13,14,15,16,17,18,19,20
So 13 desired outcomes:
Probability:
