Which comparison is correct?

r-ruslan [8.4K]

Option B: $4.5 \times 10^{-6}>3.9 \times 10^{-9}$ is the correct answer.

Explanation:

Option A: $7.1 \times 10^{8}>1.2 \times 10^{9}$

Simplifying, we get,

$710000000>1200000000$

Since, the value of $1.2 \times 10^{9}$ is greater than $7.1 \times 10^{8}$ , the comparison $7.1 \times 10^{8}>1.2 \times 10^{9}$ is false.

Hence, Option A is not the correct answer.

Option B: $4.5 \times 10^{-6}>3.9 \times 10^{-9}$

Simplifying, we get,

$0.0000045>0.0000000039$

Since, the value of $4.5 \times 10^{-6}$ is greater than $3.9 \times 10^{-9}$ , the comparison $4.5 \times 10^{-6}>3.9 \times 10^{-9}$ is true.

Hence, Option B is the correct answer.

Option C: $$2.4 \times 10^{-5}$

Simplifying, we get,

$0.000024$

Since, the value of $2.4 \times 10^{-5}$ is greater than $5.7 \times 10^{-6}$ , the comparison $$2.4 \times 10^{-5}$ is false.

Hence, Option C is not the correct answer.

Option D: $$8.2 \times 10^{-4}$

Simplifying, we get,

$0.00082$

Since, the value of $8.2 \times 10^{-4}$ is greater than $3.6 \times 10^{-6}$ , the comparison $$8.2 \times 10^{-4}$ is false.

Hence, Option D is not the correct answer.

Do the ratios 4/2 and 10/5 form a proportion? Yes or no

mars1129 [50]

Answer:

These are both 20 so that means that this is proportional, yes.

Step-by-step explanation:

Hi.

To figure this out we can do something called cross multiplying to find a cross product. If we do this and our two answers are equal then it is indeed a proportion.

Here is how we do this.

$\frac{4}{2}$ $\frac{10}{5}$

So basically what we are doing is multiplying across in a diagonal direction.

Diagonal meaning like a slash / .

So in this case we would multiply the 4 and the 5 , since they're diagonal from each other.

Do the same for the 2 and the 10.

So we have to multiply :

4 x 5

2 x 10

=

20

These are both 20 so that means that this is proportional, yes.

Hope this helps.

If you have any questions or concerns feel free to message me.

Factor completely.

antiseptic1488 [7]

Answer:

B

Step-by-step explanation:

Given

y² - 12y + 32

Consider the factors of the constant term (+ 32) which sum to give the coefficient of the y- term (- 12)

The factors are - 4 and - 8, since

- 4 × - 8 = 32 and - 4 - 8 = - 12, thus

y² - 12y + 32 = (y - 4)(y - 8) → B
