jekas [21]
<span>So the equations are 10A + 60B = 6000 and A + B = 500 

You could just solve those equations, but I would guess and check on a multiple choice test. 6000/500 = 12, which is so close to 10 that a large majority of the tickets sold were 'A' tickets. I

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.
