Answer:

1.80 or 1.8

Step-by-step explanation:

As you can see 9 is bigger than 5. But it is not a multiple of 5. you can do

9 - 5 = 4. This means that there is a whole number because 5 can go into 9 one time. Since you have taken 5 away from 9 it would be 1 and 4/5. 4 parts out of 5 is 0.80 so the decimal answer to this would be 1.80 or 1.8

Prove that 25^11−5^19 is divisible by 31.
SCORPION-xisa [38]

Answer:

Divisible by 3 is the answer

Step-by-step explanation:

First get everything to have the same base of 5

25^11 - 5^19

(5^2)^11 - 5^19

5^(2*11) - 5^19

5^22 - 5^19

Now factor out the GCF 5^19 to get

5^22 - 5^19

5^(19+3) - 5^(19+0)

5^19*5^3 - 5^19*5^0

5^19(5^3 - 5^0)

5^19(125 - 1)

5^19*(124)

At this point, we factor the 124 into 31*4 to end up with this full factorization: 5^19*31*4

Therefore, 25^11 - 5^19 is equivalent to 5^19*31*4

Since 31 is a factor of the original expression, this means the original expression is divisible by 31.

Round 905154 to the nearest ten thousand
beks73 [17]
905,154 rounded to the nearest ten thousand is 910,000. This is because the 5 in the thousands place is equal to 5, and when the number is 5 or more, you round up. That’s why when you round that number to the nearest ten thousand, it is 910,000.
