Mathematics
1 answer:
Anna71 [15]3 years ago
5 0

The inequality is a > 12, which means a is greater than 12. This means that we are looking for numbers that are greater than 12 to place into the solution set. Options A and B are incorrect because 10 and 11 are both numbers less than 12, respectively. Option D is also incorrect because the inequality specifies that the numbers in the solution must be greater than 12, not equal to it, so 12 is not a solution.

This leaves option C as the correct answer, because all of the solutions in the set (13, 14, and 15) are greater than 12.

Therefore, your answer is C.

Hope this helps!

Question is in the picture
Thepotemich [5.8K]

Answer:

$9.00

Step-by-step explanation:

If the price is at 30% discount, this means it is 100-30 = 70% of the original price.

70 \%  \ of \ original \ price = \$ 6.30\\\\\ original \ price = 6.30 \div 70 \%\\\\= 6.30 \times \frac{100}{70}\\\\=\frac{630}{70}\\\\= 9

Hence, original price is $9.00.

Calculati:
kramer

Answer:

7

Step-by-step explanation:

[(1/3 – 1/9)² + (1/3)³] : (1/3)⁴

Next, we shall simplify (1/3 – 1/9)². This is illustrated below:

(1/3 – 1/9)² = ((3 – 1)/9)² = (2/9)²

[(1/3 – 1/9)² + (1/3)³] : (1/3)⁴

= [(2/9)² + (1/3)³] : (1/3)⁴

= [4/81 + 1/27] : 1/81

= [(4 + 3)/81 ] : 1/81

= 7/81 : 1/81

= 7/81 ÷ 1/81

Invert

= 7/81 × 81/1

= 7
