(1.2 x 10-4) + (2.4 x 10-3)

Mathematics
1 answer:
ryzh [129]4 years ago
6 0

Answer:

29

Step-by-step explanation:

(1.2 x 10-4) + (2.4 x 10-3)

Simplify

1.2 x 10- 4 = 8

2.4 x 10- 3 = 21

Add both sums to get 29!

SCIENTIFIC NOTATION

2.9 x 10 to the 1st power

Move the decimal over to make a number less than ten, so that makes 2.9 and 10 to the 1st because you moved the decimal once! Hope this is better

Explain how to do this math problem all the way threw 6times2 and 7/10
Anestetic [448]
So first multiply the whole numbers.
6x2=12
Now multiply 6 and 7. When multiplying a fraction like this, do the numerator ONLY. So it ends up being 42/10.  That can be turned to a mixed number. To do that, find out how many times 10 can go into 42. The highest whole number is 4.
10x4=40 and there's 2 left over. So make it 2/10 which can be simplified to 1/5
Now add.
12+4=16+1/5= 16 1/5

What is the expanded form of 340,729​
babymother [125]

Answer:

(300,000 + 20,000 + 0 + 700 + 40 + 9)

Step-by-step explanation:

The expanded form of 320, 749

Segmenting each digit in the figure based on its place value :

3 = 100 thousand place = 3 * 100,000 = 300000

2 = ten thousand place = 2 * 10,000 = 20000

0 = thousand place = 0 * 1,000 = 0

7 = hundred place = 7 * 100 = 700

4 = tens place = 4 * 10 = 40

9 = unit place = 9 = 9

(300,000 + 20,000 + 0 + 700 + 40 + 9)
