Answer: 26 in.
Step-by-step explanation:
Given
Heights of Poles are
distance between them is
the difference in heights of the pole is
From the figure, using Pythagoras theorem, distance L is given by
The distance between tops is 26 in.
Answer:
<u>Tank 1 : </u>
height = 2x-2
length = 4x
y = l w h
= (4x) (x) (2x-2)
= (4) (2x-2)
= 8-8
<u>Tank 2: </u>
height = 6x
length = 2x-1
y = l w h
= (2x-1) (x) (6x)
= (2-x) (6x)
= 12-8
I think it is the second option but I am not sure because the picture is very unclear. Do double check with the answers I have worked out.
Hope this helps.
Answer:
it is d
Step-by-step explanation:
Answer:
16 = l
4 = w
Step-by-step explanation:
{64 = wl
{40 = 2w + 2l
{l = 8 + 2w
64 = w[8 + 2w] ↷
-64 + 8w + 2w² ↷
[2w² - 8w] + [16w - 64]
2w[w - 4] 16[w - 4]
[w - 4][2w + 16] = 0
↑
This is the expression we want because when we talk about dimensions, we want NON-NEGATIVE numbers. The other expression results in -8 = w, and we do not want that; this expression gives us a solution of 4 = w, and THIS is exactly what we want. Anyway, you plug "4" back into the system of equations and you will get a length of 16 centimetres.
