We need to add 1.45 x 10^8 and 3.9 x 10^7.
Please see..
We have given numbers in scientific form.
<em>We can't add the decimal numbers in front, because those numbers are being multiplied with 10 exponents and the exponents of 10's are not same.</em>
<em>So, we always convert the exponents of 10 as same.</em>
<em>1.45 x 10^8 could be converted to 14.5 x 10^7 to get exponent of 10 as 7 as other number 3.9 x 10^7 also has exponent of 10 as 7.</em>
<em>After this step we can just add the 14.5 and 3.9 and put × 10^7 with it.</em>
So, first correct step is:
<h3>
2. Convert 1.45 x 108 to 14.5 x 107.</h3>
The form will be y = mx + b, where m is the slope, b is the y-intercept
m = (2-7) / (3+2) = -1
b = 3 +2 = 5
So y = -x + 5
What is (41 x 24) = 984
The largest 3-digit number is 999.
999 divided by 24 is 41.625 .
To say that another way: When you have a bucket with room for 1,000 in it, you can fit 24 into it 41 times, with some space left over … but not enough to squeeze in another 24.
So the largest number less than 999 that can fit some 24s into it with no space left over is (41 x 24) = 984 .

Brainly, thank you, rating are all appreciated! Miss Hawaii : )
Answer:
Step-by-step explanation:
Zero property because you are using zeros to multiply
Answer:
5/8
Step-by-step explanation:
Freddie swam 3/8 laps yesterday
He also swam 1/4 laps today
Therefore the total lap swam can be calculated as follows
= 3/8 + 1/4
= 5/8
Hence the total lap is 5/8
