Answer:
94 m
Step-by-step explanation:
Write a proportion:
3.1 / 1.18 = x / 35.75
Cross multiply and solve:
1.18x = 3.1 × 35.75
1.18x = 110.825
x ≈ 94
Rounded to the nearest meter, the height of the tower is approximately 94 meters.
Answer:
180-43
Step-by-step explanation:
43 and x are supplementary which means they both should equal 180
4x-3y=17......(1)
5x+4y=60......(2)
Multiply equation (1) by 4 and equation (2) by 3:-
16x - 12y = 68
15x + 12y = 180
Adding these 2 equations:_
31x = 248
x = 248/31 = 8
Now substitute x = 8 in equation (1):-
4(8) - 3y = 17
32-3y = 17
-3y = -15
y = -15/-3 = 5
So solution is x=8,y=5
Since there are 2 sides to the shelf, there is 0.05*2=0.05+0.05=0.1 meters of space between the shelf and wall in total. Next, since each piece of wood is 0.3 meters wide and we have 3 of them, the total width of the wood is 0.3+0.3+<something>
Note that <width of wood>+<space between shelf and well> =width of closet
