Answer:
20 ft
Step-by-step explanation:
The 2 triangles are similar, thus the ratios of corresponding sides are equal.
let h be the height of the tree, then
= 
= 4 ( multiply both sides by 5 )
h = 20
The height of the tree is 20 ft

Answer:
B. about 40 miles
Step-by-step explanation:
We need to find the miles traveled per hour. We can do this by taking the total number of miles traveled and divide it by the time it took to travel that distance. Converting 7 and 3/4 hours to decimals is 7.75 hours.
328.9 miles / 7.75 hours = 42.44 miles/hour
The closest answer is B, about 40 miles.
Answer:
<h2>19,600 J</h2>
Step-by-step explanation:
The potential energy of a body can be found by using the formula
PE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 9.8 m/s²
We have
PE = 500 × 9.8 × 4
We have the final answer as
<h3>19,600 J</h3>
Hope this helps you
