Answer:
15,000 or 1.5 x 10^4
Step-by-step explanation:
First you put 2.5 x 10^3 in expanded form which is 2,500. Second you put 6 x 10 in expanded form which is already in expanded form, which is 6. Lastly you multiply 2,500 times 6 to get your answer of 15,000 which you either keep the same or change to scie tific notation
Hope I could help
53 as a prime number would be 1 and 53
Hello!
GCF, or greatest common factor, is the greatest factor shared between two numbers. (A factor is something which you can divide a number by to get a whole number)
To do this, first list out all the factors of 21 and 25. (There are other methods to do this, but, this method will work for smaller numbers)
21: 1, 3, 7, 21
25: 1, 5, 25
As you can see, the greatest factor shared between them is the number 1.
Therefore, the GCF of 21 and 25 is 1.
Hope this helps!
(Side note: a better method to do this for larger numbers is to list out the prime factorization for each number, then find all the numbers in common, and multiply)
Answer:
a = -4
Step-by-step explanation:
a + c = 6
substitute 10 for 'c'
a + 10 = 6
a = -4
Answer:
2, 46%
Step-by-step explanation:
==>Given:
Number of Children=>Frequency
0=>225
1=>112
2=>460
3 =>101
4=>68
5 or more=>34
Total no. of couples surveyed=>1000
==>REQUIRED:
No./% of children with the highest frequency.
==>SOLUTION:
The no. of children that occurred the most is 2, having a frequency of 460.
The % = 460 ÷ 1000 × 100
= 0.46 × 100
= 46%
Our answer is 2, 46. The number of children 2, which occurs most frequently has a percentage of 46.
