The problem presented above is an example in which we can use the concept of ratio and proportion. The ratio between the heights of Mei and the statue should be the same to the ratio of their shadows. Letting x be the height of the statue.
5 ft/ x ft = 3 ft / 10.5 ft
The value of x from the equation above is 17.5 ft.
step 1: open brackets n rmb to flip the signs
step 2 (optional): rearrange to make the equation clearer to add/minus
length of 3rd side:
(8x + 3) - (2x + 1) -(5x + 2)
= 8x + 3 - 2x -1 - 5x -2
= 8x -2x -5x +3 -1 -2
= x
Therefore, length of 3rd side is X cm.
---
If perimeter = 75cm,
8x +3 = 75
8x = 75-3
8x = 72
x = 9 cm
Therefore,
1st side = 2(9) +1
= 19 cm
2nd side = 5(9) +2
= 47 cm
3rd side = 9 cm
Answer:
5683.2 Euro's
Step-by-step explanation:
i=
p=7400 Euro's
r=12.8*1/100
t=6yrs
I=P*R*T
7400*12.8/100*6
=5683.2 Euro's
The distance between the Earth's surface and the upper edge of the Earth's atmosphere would be Q - V.
The distance from the Sun to the Earth is Q. The distance from the Sun to the upper edge of the atmosphere is V. If you subtract V from Q, the remaining distance is that of the Earth's atmosphere. Q - V = the atmosphere
6x+3-(8x-5)
=
-2x(x-4)
=
2x+8
=
p = 2
