dimaraw [331]

8th Grade: 90 x 0.80 = 72

7th Grade: 80 x 0.75 = 60

Conclusion: 8th Graders like pop music more because 72 out of the 90 in 8th grade Dave surveyed enjoy it, compared to the 60 out of 80 in 7th grade that enjoyed it.

Calculate the value of (6.72 10^5)+ (3.2 x 10^4) Give your answer in standard form.

dangina [55]

Answer:

$7.04\cdot 10^{5}$ or 704,000

Step-by-step explanation:

Standard Form of Numbers

Any number that we can write as a decimal number between 1.0 and 10.0, multiplied by a power of 10, is said to be in Scientific Notation. Some authors consider standard form and scientific form as the same, but others state that standard form is the common form of expressing numbers, i.e., a sequence of digits, separated by thousands by a comma, and separated from the decimal part by a dot.

We'll give here both answers.

We have to calculate:

$6.72\cdot 10^{5}+3.2\cdot 10^{4}$
