Answer:
Every day Dajuan will paint 14.5 square feet of the wall.
Step-by-step explanation:
Since Dajuan is painting a mural on a rectangular wall, which measures 14.5 feet long and 10 feet wide, and so far, his mural covers 60% of the wall, and Dajuan will paint the remaining part of the wall over the next four days, painting the same amount of the wall, in square feet, on each of those four days, to determine how much of the wall, in square feet, will Dajuan paint on each of the next four days, the following calculation must be performed:
((14.5 x 10) x 0.4) / 4 = X
(145 x 0.4) / 4 = X
58/4 = X
14.5 = X
Therefore, every day Dajuan will paint 14.5 square feet of the wall.

Crowbar is a Class A lever
Therefore the mechanical advantage of the crowbar can be given by either:
MA = Output distance/Input distance
OR
MA = Output force/Input force
Since, the question gives only the force, we can use the second formula.
MA = Output force/ Input Force
= 330 N / 30 N
= 11</span>
Total heads = 10
Total legs = 26
Cat = 4 legs
Birds = 2 legs
------------------------------------
Assumed all birds :
------------------------------------
Total legs = 10 x 2 = 20
------------------------------------
Difference in legs :
------------------------------------
26 - 20 = 6
------------------------------------
Difference in legs between the two animals:
------------------------------------
4 - 2 = 2
------------------------------------
Find number of cats :
------------------------------------
6 ÷ 2 = 3
------------------------------------
Find number of birds :
------------------------------------
