Answer:
LXXXVII
Step-by-step explanation:
L=50 X=10 V=5 I=1
So basically you need to figure out what adds up to the 87. so use L, or 50. now XXX=30. so now you have 80 so we still have 7 left over, so we can write 7 I's or a 5, (V) and two I's. We should use the V and the I. So we take one V, or 5. and two I's which together is 7. which leads us too LXXXVII. also always remember to have the biggest number first, in this case the L (50).
Answer:
30 feet
Step-by-step explanation:
Interesting question.
- 1 cubit = 18 inches
- 20 cubits = x
- 1/20 = 18/x Cross multiply
- x = 20 * 18
- x = 360 inches.
The maximum height is 360 inches.
- 1 foot = 12 inches
- x feet = 360 inches Cross multiply
- 12x = 360 * 1
- 12x/12 = 360/12
- x = 30
The maximum height reached was 30 feet.
In can be less mental effort if the equation is multiplied by -1 first.
.. x^2 -10x +8 = 0
.. x^2 -10x +25 +8 -25 = 0
.. (x -5)^2 = 17
.. x -5 = ±√17
.. x = 5 ±√17
The values of x that satisfy the given equation are
.. x = 5 -√17 ≈ 0.877
.. x = 5 +√17 ≈ 9.123
