Explanation

To add these fractions, we need to find a common denominator, which is 77 (7 x 11). So, we'll convert both fractions to have a denominator of 77:

(3/7) = (3 x 11) / (7 x 11) = 33/77

(6/11) = (6 x 7) / (11 x 7) = 42/77

Now, we can add:

33/77 + 42/77 = 75/77

To convert this to a decimal, we'll divide the numerator by the denominator:

75 ÷ 77 = 0.974 (approximately)

So, the correct answer is: 0.97

Explanation

4 + 5 - 3 = 6.

First, add 4 and 5 to get 9, then subtract 3 to get 6.

Explanation

1300 × 5 = 6500

Explanation

5 is an odd number because it is not divisible by 2.

Unlike 6, 4, and 2, which are even numbers.

Explanation

(-6) 1/2 (-10)=?

= - 6  -10 x 1/2

= 6 x 1/2

= 60 / 2

= 30

Second Solution

To find the product of $(-6)\times \frac{1}{2}\times (-10)$

Explanation

The greatest 9-digit number is 999,999,999.

Explanation

We need to choose a 4-student committee from a panel of 12 students. This is a combination problem, as the order of selection doesn't matter. We can use the combination formula:

C(n, k) = n! / (k!(n-k)!)

where n is the total number of students (12), k is the number of students to be chosen (4), and ! denotes the factorial function.

C(12, 4) = 12! / (4!(12-4)!)

= 12! / (4!8!)

= (12 × 11 × 10 × 9) / (4 × 3 × 2 × 1)

= 495

So, there are 495 different ways to choose a 4-student committee from a panel of 12 students.
