Answer:

<h3>Lucas and Zoe will both next visit their mother on 7th of May at the same time.</h3>

Step-by-step explanation:

First, find the first multiple that can be divisible by 5 and 8:

40 is divisible by 5 and 8.

Second, find the days in April and subtract 7 from the days:

April=30 days.

30-7= 23 days.

Finally, subtract 23 from 40 and find it in the next month, which is May:

40-23=17

Therefore, they will both next visit their mother on the 7th of May.

2. The area of a square is 72 sq in. What is its side length?

defon

Answer:

$6 \sqrt{2}$

if you don't have to simplify it, it is

$\sqrt{72}$

Step-by-step explanation:

the equation for the area of a square is

$a = {s}^{2}$

substitute 72 for a

$72 = {s}^{2}$

take the square root of both sides to cancel out the square on the s

$\sqrt{72} = \sqrt{ {s}^{2} }$

$\sqrt{72} = s$

if you need it simplified, find the perfect square that makes up 72. It is 36.

$\sqrt{36 \times 2} = s$

take the square root of 36

$6 \sqrt{2} = s$

the set $s = \$ contains the first $50$ positive integers. after the multiples of 2 and the multiples of 3 are removed, how many

Sophie [7]

Clearly, |S| = 50.

Count the multiples of 2 between 1 and 50:

⌊50/2⌋ = ⌊25⌋ = 25

(where ⌊x⌋ denotes the "floor of x", or the largest integer that is smaller than or equal to x; in other words, round down to the nearest integer)

Count the multiples of 3 between 1 and 50:

⌊50/3⌋ ≈ ⌊16.667⌋ = 16

Since LCM(2, 3) = 6, the sets of multiples of 2 and multiples of 3 have some overlap. Count the multiples of 6 between 1 and 50:

⌊50/6⌋ ≈ ⌊8.333⌋ = 8

Then by the inclusion/exclusion principle, we remove from S

25 + 16 - 8 = 33

elements, so that the new set S contains 50 - 33 = 17 elements.
