Kyra observed that 85% of the students at a library liked reading mystery stories. If 30 students at the library did not like re
boyakko [2]
First  calculate that numeric value. It cannot be done immediately without calculations.

if 85% of studends liked mystery that means that 100% - 85% = 15% didnt like.

Those 15% are 30 that were given in text. Now we can calculate this using proportion:

15%        30 students
85%         x students

we use cross multiplication:
15*x = 30*85
x = 30*85/15
x = 170

Answer is 170

Show that from any subset of 51 numbers taken from {1, 2, 3, ..., 100}, there exists a pair of elements such that one divides an
Sunny_sXe [5.5K]

Consider the 50 odd numbers 1,3, 5, ..., 99.

For each one, form a box containing the number and all powers of 2 times

the number.

So the first box contains {1,2,4,8, 16,..}

the next box contains {3,6,12,24,48, ...}

Then among the 51 numbers chosen, the pigeonhole principle tells us that there are two that are contained in the same box. They must be of the form 2^{m} k and 2^{n} k with the same odd number k. So one will divide the other.

<h3>What is pigeonhole principle?</h3>

According to the pigeonhole principle, if n items are placed in m containers, with n > m, at least one container must contain more than one item.

For example, if you have three gloves (and none of them are ambidextrous/reversible), you must have at least two right-handed gloves or at least two left-handed gloves, because there are three objects but only two categories of handedness to put them into.

Y=(4x)^3

Y=64x^3

Step-by-step explanation:

Y=(3√x)÷4

Making X subject of formula

4y= (3√x)

(4y)^3= (3√x)^3

(4y)^3 = X,

Replacing Y with X

Y=(4x)^3

Y=64X^3
