Answer: the distance of the base of the house to the foot of the ladder is 6.84 feet
Step-by-step explanation:
The scenario is shown in the attached photo.
Right angle triangle ABC is formed when the ladder leans against the wall of the house.
AC = the height of the ladder
AB = x feet = distance of the base of the house to the foot of the ladder
BC is the wall of the building.
To determine x, we will apply trigonometric ratio
Cos # = adjacent/hypotenuse
Where
# = 70 degrees
Hypotenuse = 20
Adjacent = x
Cos 70 = x/20
x = 20cos70
x = 20 × 0.3420
x = 6.84 feets
Y=4x+4
I think this is it u just have to simplify to get it to y=mx+b
Answer:
0.002 BTUs per cubic foot heat is produced per hour
Step-by-step explanation:
Given:
Number of person = 2
Amount of heat produced by one person = 2.400 BTU
Dimension of the room = 20 ft x 12 ft x 10 ft
To Find:
How many BTUs per cubic foot do they produce in 1 hour = ?
Solution:
E =![\frac{ \text{(2400 Btu/ person hr}) (\text{Number of Hours}) (\text{Number of persons }) }{\text {volume of the room}}](https://tex.z-dn.net/?f=%5Cfrac%7B%20%5Ctext%7B%282400%20Btu%2F%20person%20hr%7D%29%20%28%5Ctext%7BNumber%20of%20Hours%7D%29%20%28%5Ctext%7BNumber%20of%20persons%20%7D%29%20%7D%7B%5Ctext%20%7Bvolume%20of%20the%20room%7D%7D)
Substituting the values
E = ![\frac{ \text{(2400 Btu/ person hr}) (1) ( 2) }{20 ft \times 12 ft \times 10 ft}](https://tex.z-dn.net/?f=%5Cfrac%7B%20%5Ctext%7B%282400%20Btu%2F%20person%20hr%7D%29%20%281%29%20%28%202%29%20%7D%7B20%20ft%20%5Ctimes%2012%20ft%20%5Ctimes%2010%20ft%7D)
E = ![\frac{4.800}{2400}](https://tex.z-dn.net/?f=%5Cfrac%7B4.800%7D%7B2400%7D)
E = 0.002 BTU per cubic feet
