The mass of a grain of sand is about 10−3 gram. about how many grains of sand are in the bag of sand? the bag has 10kg of sand

10000000 or grains of sand

Step-by-step explanation:

The mass of a grain of sand is about gram.

Total weight of the sand in a bag is = 10 kg = 10000 gms

Let there are n grains of sand in the bag weighing 10 kg of sand.

So weight of n grains will be = number of grains × weight of one grain = 10000

n = 10000 × 1000 = 10000000

n =

Therefore answer is grains of sand

the y will be in still but your answer will be y x 3

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
