Suppose 2kg of sugar contains 9*10 crystals.How many sugar crystals are there in 5 kg of sugar???2)1.2kg of sugar

Answers

Answer 1

Answer:

Answer:

225

Step-by-step explanation:

9*10 = 9 times 10 = 90

2kg = 90

that means 1kg = half of 90 = 45

1kg = 45

5 kg = 45 times 5 = 225

By the way at the end of your question you put "2)1.2kg of sugar" but I don't know what that is so i ignored it

Hal forgot the number of people at the basketball game.He does remember that the number had four digits and a 3 in the tens place. write a number that Hal could be thinking of.

Answers

Answer:

Number of People in the basketball game =A four digit number having 3 in the tens place.

Total number of digits in all={0,1,2,3,4,5,6,7,8,9}=10

So, Required Number,that is number of people at the basketball game which is a four digit number,also digits can repeat

=(0 can't be at Unit place ,so first digit that is number at thousands place can be selected in 9 ways)(Number at Hundred place can be selected in 10 ways )(3 in tens place)( Number at Unit place can be selected in 10 ways )

=9939(Maximum People)

Total number of four digit numbers , if these condition are given

=9×10×1×10

=900

There are a lot of numbers you can think of, for example, 1030, or even 9939, but I don't recommend you put that ;)
