Answer:
36
Step-by-step explanation:
Multiples of 4 (from 1-40)
4, 8, 12, 16, 20, 24, 28, 32, 36, 40
Multiples of 8 (from 1-40)
8, 16, 24, 32, 40
4, 12, 20, 28, 36 is one of them. Find out the factors of the 5 numbers.
4 = 1 x 4
12 = 1 x 12
= 2 x 6
= 3 x 4
20 = 1 x 20
= 2 x 10
= 4 x 5
28 = 1 x 28
= 2 x 14
= 4 x 7
36 = 1 x 36
= 2 x 18
= 3 x 13
= 4 x 9
= 6 x 6
That's about it, so 12 or 36 is the answer. Now find out which of the 2 numbers is a perfect square.
To find out a perfect square, the 2 numbers multiplying in have to be the same number.
6 x 6 = 36
So 36 is a perfect square since there are no 2 numbers which are the same value that can make up 12.
The distance traveled by the balloon in every minute makes an arithmetic sequence with a first term equal to 40 ft and common difference equal to 20. The nth term of an arithmetic sequence is calculated by,
an = a1 + (n - 1) x d
Substituting,
an = 40 + (15 - 1) x 20 = 320
Thus, the answer is letter B. 320 feet.
Two buckets of seawater contain kg of salt.
Step-by-step explanation:
Amount of salt in 1 kg water =
It is given that;
1 liter =
500 liters =
500 liters = 548 kilogram
As,
1 kg of seawater = of salt
548 kilograms =
548 kilograms = kilograms of salt
Two buckets of seawater contain kg of salt.

And the tables will help you and so will this.
Step-by-step explanation:
Look at the value for question of getting an answer right and you have to do a table that looks like this attached
4 games at 2/3 chance for each = 16/27
We look at 1/3 x 1/3 = 11/ 20
we look at 2/3 x 2/3 = 0.444 = 22/50 = 11/25
The other two games are
1/3 x 2/3 = 0.22 + 0.22 = 0.44
0.44 = 11/25
+ 3/20
= 16/27
It wont be as complicated as that. But im sure this will help.
