Answer:
3 metres
Step-by-step explanation:
If we draw this out, we'll see that there are actually two similar right triangles (see attachment), which means that we can set up a proportion.
The height of the lookout tower corresponds to the height of the wooden column, while the shadow of the lookout tower corresponds to the shadow of the wooden column. We can then write:
(height of lookout tower) / (shadow of tower) = (height of column) / (shadow of column)
16 / 12 = 4 / x , where x is the shadow / unknown we want to find
Cross-multiply:
16x = 48
x = 3
The answer is thus 3 metres.
Answer:
I think it's 92 ft squared. I'm a lil bad at mental math but that's what I got.
Answer:
y = -13/16
Step-by-step explanation:
<u>Given:</u>
0.8y+0.25= -0.4
<u>To Find:</u>
Solve for y
<u>Solution:</u>
Multiply both sides by 100
Simplify
Subtract 25 from both sides
Simplify
Divide both sides by 80
Simplify
Thus, y = -13/16
or in decimal form it equal y = -0.8125

Answer:
No
Step-by-step explanation
Because 20 more pages would take 35 more minutes which would be 40 pages at 70 mines then you will divide your 7 pages left by the 35 minutes it took to read the the first two 20 page sections of the book.
35 min.+ 35 min = 70 min. 35 mins./7 pages = 5 mintes
So it took a total of 75 minutes for Line to read her 47 page book.
