Jean writes 75,000,000 in scientific notation as 75 . Explain whether she is correct or incorrect.

As Jean writes 75,000,000 in scientific notation as 75.

This is INCORRECT!

The correct solution is:

75,000,000 in scientific notation: 7.5 × 10⁷

Step-by-step explanation:

As Jean writes 75,000,000 in scientific notation as 75.

This is INCORRECT!

Here is the correct solution:

Given the number

75,000,000

Let us write the number 75000000 in scientific notation

We know that scientific notation is of the form where and b is an integer.

Move the decimal point to the left to create a new number from 1 up to 10.

Count the number of times you moved the decimal point

b = 7

so

Remove the trailing zeros

Therefore, we conclude that:

75,000,000 in scientific notation: 7.5 × 10⁷

∠1≅∠2 by the alternate exterior angles theorem.

step-by-step explanation:

given, a ∥ b and ∠1 ≅ ∠3 .we have to prove that e ∥ f

we know that ∠1≅∠3 and that a || b because they are given. we see that by the alternate exterior angles theorem. therefore, ∠2≅∠3 by the transitive property. so, we can conclude that e || f by the converse alternate exterior angles theorem.

we have to fill the missing statement.

transitivity property states that if a = b and b = c, then a = c.

now, given ∠1≅∠3 and by transitivity property ∠2≅∠3 .

hence, to apply transitivity property one angle must be common which is not in result after applying this property which is ∠1.

the only options in which ∠1 is present are ∠1 and ∠2, ∠1 and ∠4

∠1 and ∠4 is not possible ∵ after applying transitivity we didn't get ∠4.

hence, the missing statement is ∠1≅∠2.

so, ∠1≅∠2 by the alternate exterior angles theorem.

22.83 repeating

step-by-step explanation:

137 ÷ 6 is 22.8333333 therefore we understand that 3 is repeating.
