Answer:
42.9 ft
Step-by-step explanation:
The relevant trig relation is ...
Tan = Opposite/Adjacent
where Opposite in this case is the height of the tree, and Adjacent is the distance to the tree.
tan(47°) = height/(40 ft)
height = (40 ft)·tan(47°) . . . . . multiply both sides by (40 ft)
height ≈ 42.9 ft
The tree is about 42.9 feet tall.
Answer:
1100
Step-by-step explanation:
Rounded to nearest hundred
Here we will tell you what 1058 is rounded to the nearest hundred and also show you what rules we used to get to the answer.
Remember, we did not necessarily round up or down, but to the hundred that is nearest to 1058.
First, 1058 rounded to the nearest hundred is:
1100
When rounding to the nearest hundred, like we did with 1058 above, we use the following rules:
A) We round the number up to the nearest hundred if the last two digits in the number are 50 or above.
B) We round the number down to the nearest hundred if the last two digits in the number are 49 or below.
C) If the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.
To solve this, you have to use the unit rate (20/5=4), and you also have to convert meters to kilometers.
