Answer:
a) 9000 ft-lb
b) 9000 ft-lb
Step-by-step explanation:
Equation for the work:
The equation for the work done is given by:

In which F is the force needed and d is the distance. The time does not interfere on the work.
A 300-lb gorilla climbs a tree to a height of 30 ft
This means that 
Thus

The work done in both cases is of 9000 ft-lb, as the work is not a function of time.
Answer:
A not similar
Step-by-step explanation:
These triangles are not similar
<K would have to equal either angle E or D since angle F equals angle F
E = 50 and D = 58 and K = 49 so K does no equal E or D so they cannot be similar
Answer:
the digit 4 in 3.546 is called hundredth because it is after the decimal point you add -th behind it while the digit 4 in 4.23 is called a unit
1.Identify the fractions. Using the distributive property, you’ll eventually turn them into integers.
2.For all fractions, find the lowest common multiple (LCM) -- the smallest number that both denominators can fit neatly into. This will allow you to add fractions.
3.Multiply every term in the equation by the LCM.
4.Isolate variables adding or subtracting like terms on both sides of the equals sign.
5.Combine like terms.
6.Solve the equation and simplify, if needed.
