Answer:
first piece = 1.88in
second piece= 3.76in
third piece = 26.32in
32 = f + s + t
1st piece = f
2nd piece = s
3rd piece = t
what we know:
s = 2f
t = 2(7f)
32 = f + 2f + 2(7f)
32 = 3f +14f
32 = 17f
f = 1.88
now sub in:
f = 1.88
s = 3.76
t = 26.32
when you add these together you get 31.96, when you round up you get 32 which is the original piece of steel.
1. 46.93 ft/1 sec = x ft/ 1.8 sec
2. cross multiply
3. 1x= 84.474
4. x= 84.474 ft
Answer: x=10 and y=25
Step-by-step explanation:
ok, so since we know straight angles=180 degrees, so since one part=100, the other smaller angle=80. This means that 11x-30=80 and 5y-25=100. 11*10=110, and 110-30=80, so x=10. 5*25=125, and 125-25=100, so y=25. And lol. me too. When I used to do these problems, I was stuck for a very, very long time. Just try to use logic most of the time.
Answer:
x=20
Step-by-step explanation:
Answer:
The minimum distance x that a plant needing full sun can be placed from a fence that is 5 feet high is 4.435 ft
Step-by-step explanation:
Here we have the lowest angle of elevation of the sun given as 27.5° and the height of the fence is 5 feet.
We will then find the position to place the plant where the suns rays can get to the base of the plant
Note that the fence is in between the sun and the plant, therefore we have
Height of fence = 5 ft.
Angle of location x from the fence = lowest angle of elevation of the sun, θ
This forms a right angled triangle with the fence as the height and the location of the plant as the base
Therefore, the length of the base is given as
Height × cos θ
= 5 ft × cos 27.5° = 4.435 ft
The plant should be placed at a location x = 4.435 ft from the fence.
