we know that
A quadratic equation is a polynomial with an order of two. Its general form is
case a) 
<u>The case a) is a quadratic equation</u>
case b) 
<u>The case b) is a grade 
polynomial</u>
case c) 
<u>The case c) is a grade 
polynomial</u>
case d) 
<u>The case d) is a grade 
polynomial</u>
therefore
the answer is
Answer:
12.5
Step-by-step explanation:
40% is 0.4. 0.4 is 1/4. 1/4 * 50 is 12.5
Answer:
B
Step-by-step explanation:
The sum of the 3 interior angles of a triangle = 180°
Check the sums of the given sets of angles
90° + 42° +58° = 190° ≠ 180° ← not valid
60° + 60° + 60° = 180° ← Valid
100° + 48° + 42° = 190° ← not valid
31° + 75° + 70° = 176° ← not valid
Answer:
B im pretty sure
Step-by-step explanation:
Remark
The key to this question is to get the original price (36) down to 29.52. In other words, what % will when multiplied by 36 will result in 29.52?
Solution
36 * (x/100) = 29.52 Multiply both sides by 100
36 * x = 29.52 * 100 The 100 on the left disappears.
36 * x = 2952 The decimal disappears. Divide by 36
x = 2952/36
x = 82%
That is not your answer. That just tells you what % of 36 is that would give 29.52
Answer
The % discount is 100 - 82 = 18%. That is the % discount.
