[計量] 最後的印度數量提問!
又要麻煩大家了!
Given a big square, in which 16 small squares were inscribed. The small ones
which had only 1 side covered with perimeter of big square was shaded. If n
is the number of such small shaded squares in a big square(n>4), then find
the actual number of small squares within a big square?
A. 4(n-4)
B. 4(n-2)
C. 2(n-4)
D. 2(n-2)
& so on......
(something like this)
Ans: A
這題我沒算出、雖然有劃出16個大小不全相同的小正方形，
但從我畫出的圖去算n和共有多少個小正方形的答案卻不在選項中
Given a ladder of length 5mts and it is displaced i.e slanted downwards, such
that it falls 'x' mts in height and horizontal length increases by 'y' mts.
Col A: x
Col B: y
Ans: B
說一樓梯原貼著牆，後滑出去了，問降低的高度與底部滑出的長度
可以告訴我以數學式子解釋為何？
A regular hexagon ABCDEFG is inscribed in a circle. If BE is the diameter of
the circle, then
Col A: Length of BE
Col B: Length of BCD
Ans: C
題目錯了？
There are some toys and some crates and when these toys are equally
distributed in the crates none are left. If there are 3 less crates, then
each crate consists of 12 toys with 27 toys left. Find how many toys were
there?
是無數解嗎？ => 12(x-3)+27
If N = 5^9 + 7^10, then
Col A: What is the least factor of 'N' greater than 1
Col B: 3
答案是Ａ嗎？
There are 28 men in a room in that 14 men are selected out of which 7 are
under 50years
Col A: Percentage of men under 50
Col B: 40%
題意是28人中挑14人，而這14人中有7人under 50years？
The students were given two sets of questions; they can mark either yes/ no
or can leave it as unanswered. If 1000 people were asked, for first question
if
400 answered YES
340 answered NO &
260 left unanswered and for second question, if
450 answered YES
310 answered NO &
240 left unanswered,
then, find the minimum number of people who gave unanswered option for both
questions?
我認為是零，但我沒有答案，所以想請問大家的答案。
Given two circles of equal size and the distance between their centers is 12.
If the two circles coincide each other & distance between their edges is 4,
then find the area of any one of the circle?
既然兩相同圓重疊，又哪來的凌edge（找不到那個菱的字…..）?
Given a function f which is defined for each positive three digit integer 'n'
as f(n) = (2^x)*(3^y)*(5^z), where x, y and z are hundreds, tens and units
digits of n, respectively. If m and v are three-digit positive integers such
that f(m) = 9f(v), then what is the value of m - v?
A. 8
B. 20
C. 19
& so on.......
從f(m) = 9f(v)去看(2^x)*(3^y)*(5^z)來求m, v 可是在設完Xv,Yv,Zv,Xm,Ym,Zm我還是
沒找出上面方程式提供的線索
What is the value of 10^2 - (1/10^4) + 2^4 - (1/2^4)?
請問這題有甚麼撇步比較快求解?
我沒看出有甚麼特殊結
