if 35 is LESS than 39
so +35 - 39 is -4 F°
the answer to the freezing point of (hehe) butter is -4 F°
If in a fraction, the numerator or the denominator or both are fractions, then it is called a complex fraction.
Example 1:

Here, since the numerator is a fraction, it is a complex fraction.
Example 2:

Here, since the numerator and the denominator are fractions, it is a complex fraction.
Option D:
Right triangle
Solution:
Let us first define obtuse, acute right triangle and supplementary.
<u>Obtuse angled triangle:</u>
If any one of the angle in the triangle is more than 90°, then the triangle is an obtuse angled triangle.
<u>Acute angled triangle:</u>
If all the angles of the triangle are less than 90°, then the triangle is an acute angled triangle.
<u>Right angled triangle:</u>
If any one of the angle in the triangle is exactly 90°, then the triangle is a right angled triangle.
<u>Supplementary:</u>
If sum of the angles is 180°, then the angles are supplementary angles.
But this is not a kind of triangle.
In given triangle one of the angle is 90°.
Therefore, this is a kind of right triangle.
Option D is the correct answer.
Percentage wise, we are understanding that 100% of the population equals all 3,600 students, and that only 40% eat cold pizza for breakfast. This means that 60% do not eat cold pizza for breakfast, so:
3600 students x 0.6 (or 60/100) = 2,160 students who do not eat cold pizza for breakfast.
Rounding as accorded to the question, the answer would then be 2,200 students when rounded to the hundredths place.
