Explain how you could use mental math to find a 15% tip for a $26 restaurant bill.

1 answer:

3 0

10% of 26 is 2.60. Now, half of that is 1.30. Add both of them and you get 3.90. Same logic can work for a 20% tip, just double to 10%.

Is 14,48,50 a Pythagorean triplet <br> Step by step explanation please

Svetlanka [38]

Answer:

yes

Step-by-step explanation:

If the values are a Pythagorean triplet then the square of the largest value should equal the sum of the squares of the other 2

largest value = 50 ⇒ 50² = 2500

14² + 48² = 196 + 2304 = 2500

Since 50² = 14² + 48² then 14, 48, 50 are a Pythagorean triplet

The equation to find the number of assignments in the math section of Savannah's binder is 197 = x + 132

<h3>Equation</h3>

Assignment in the history, science, and art sections combined = 132 assignment

Assignment in the math section = x

Total assignment = 197 assignments

Total assignment = Assignment in math + Assignment in other subjects

197 = x + 132

197 - 132 = x

65 = x

Therefore, the equation to find the number of assignments in the math section of Savannah's binder is 197 = x + 132
