Answer:
72
Step-by-step explanation:
Multiply 72 by .75 and you get 54
2/7 as a fraction rounds to 0.3
0.3 * 3 = 0.9
3 x 2/7 is less than 3
Answer:
If the length of a tree's shadow is 35.25 meters. The height of the tree to the nearest hundredth of a meter will be : 11.74m
Given:
Denora height=1.35 meters
Length =35.25 meters
Width =31.2 meters
Height of the tree=x
Proportion:
1.35 : 35.25 :: x : 31.2
Now let's determine the height of the tree:
35.25 - 31.2 / 1.35 = 35.25 / x
4.05 / 1.35 = 35.25 / x
Cross multiply
4.05x = 35.25 × 1.35
4.05x = 47.58
Divide both sides
x = 47.58 / 4.05
<u>x = 11.74</u>
In conclusion, if the length of a tree's shadow is 35.25 meters. The height of the tree to the nearest hundredth of a meter will be: 11.74m
We know that:
1 mile = 5280 ft
1 minute = 60 sec
Therefore to convert this we simply use the conversion
factors:
(30 ft / s) * (60 s / 1 min) * (1 mi / 5280 ft) = 0.34 mi
/ min
So we got 0.34 miles per minute.
3 and 1 are your corresponding angles. So A.
