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.

The sum of 7 and 2 is 8

BabaBlast [244]

Answer:

We can introduce a variable ( a letter representing an unknown ) to help us solve this question.

Let χ = "a number..."

We can rewrite the sentence in the following way:

7( χ + 2 ) = 8

To solve for χ , we can first distribute 7:

7 ∗ χ + 7∗(2) = 8

7χ + 14 = 8 ⇐ since 7 times 2 is 14

Let's get χ by itself first. We do so by subtracting 14 from both sides of the equation:

7χ + 14 - 14 = 8 - 14

7χ + 0 = -6 ⇐

7χ = -6 ⇐

The last number in our way is that 7. Let's divide both sides by 7 ( which is the same as multiplying both sides by 1 / 7 ) to figure out what χ is:

7χ ∗ ( 1 / 7 ) = -6 ∗ ( 1 / 7 )

χ ∗ ( 7 / 7 ) = - 6 / 7 ⇐

χ ∗ ( 1 ) = - 6 / 7 ⇐

χ = - 6 / 7

Therefore ( we can also use ∴ to represent the word "therefore" ) our number in question is -6 / 7
