10,534,341 is divisible by<br> a. 3<br> b. 9<br> c. 2<br> Explain your reasoning for your choice(s).
Katyanochek1 [597]

Answer:

a. 3

Step-by-step explanation:

We can get to know if a number is divisible by 3 if after adding all the digits of that number we get a number which is completely divisible by 3 or we can say the number appears in the table of 3.

For example: In the given number if we will add all the digits the we will get  21 and we all know that 21 is divisible by 3.

10,534,341 = 1 + 0 + 5 + 3 + 4 + 3 + 4 + 1 = 21

21 = 21/3 = 7

Other options are incorrect.

Divisibility rule for 2 : A number is said to be divisible by 2 if it's ones place ends in 0, 2, 4, 6 or 8 i.e. an even number. The given number does not satisfy this condition because it ends in 1 which is an odd number.

Divisibility rule for 9 : A number is said to be divisible by 9 if after adding all the digits of that number we get a number which is completely divisible by 9. Since the sum total of the given number is 21 which is not completely divisible by 9 we can easily infer that 9 is not the answer for this question.

Someone pls do these 3 for me, its due in 20 minutes and my head hurts so bad right now :(
Drupady [299]

Answer:

1. Chloe has more money.

2. Dylan does <u>not</u> have enough money to buy 3 bags of candy.

3. Mikayla could get 4 pennies, 2 nickels, 2 dimes, and 2 quarters back in change.

Step-by-step explanation:

Penny = 1 cent

Nickel = 5 cents

Dime = 10 cents

Quarter = 25 cents

1. Chloe has 2 quarters(50 cents) and 3 dimes(30 cents). 50 + 30 = 80 cents

Haru has 5 nickels(25 cents) and 4 dimes(40 cents). 25 + 40 = 65 cents

2. If each bag costs $350(oddly enough). Dylan would need $1,050 to buy 3 bags of candy. Instead he only has $10. This means he would need $1,040 more dollars.

3. $5 - 4.16 = 84 cents in return

quarter(25) + quarter(25) + dime(10) + dime(10) + nickel(5) + nickel(5) + penny(1) + penny(1) + penny(1) + penny(1) = 84 cents
