Answer 1

Answer: 1. Rational numbers can be written as a ratio (fraction)
Whole numbers are rational. 5 = 5/1, for example.
Square roots are NOT rational. Example: √3
However, square roots of square numbers can be simplified, and are therefore rational. √4 = 2, rational.

√4 + √16 = 2 + 4 = 6. rational
√5 + √36... irrational
√9 + √24... irrational
2 × √4 = 2 × 2 = 4. rational
√49 × √81 = 7 × 9 = 63. rational
3√12... irrational

2. $n^\frac12=\sqrtn$
$9^\frac32=9^3*\frac12=√(9^3)=√(729)=29$

3. $(n^a)/(n^b)=n^(a-b)$

$(a^\frac13)/(a^\frac14)=a^(\frac13-\frac14)=a^{(1)/(12)}$

4. $n^\frac1x=\sqrt[x]n$

$\sqrt[3]{m^2n^5}=m^(\frac23)n^(\frac53)$

5. $√(a)*√(b)=√(ab)$

$√(3)*√(12)=√(3*12)=√(36)=6$

A, since neither 3 nor 12 is a square but we end up with 6.

Fraction number is the rational number. The number which is above the ratio line is called numerator and the number which below the ratio is called the denominator.Fraction name of each part in words is one fourth and Fraction of each part in number is 1/4.

The given figure is image of a triangle.This triangle is further divided into the four triangle. To solve this we must have the idea about the fraction number.

What is fraction number?

Fraction number is the rational number. The number which is above the ratio line is called numerator and the number which below the ratio is called the denominator

Now we have total four part. All this four parts of the triangle is equal to the each other.Thus each part is equal to the one fourth of the big triangle.

The fraction that names each part-For the given figure as it is divided into the 4 equal parts hence, the each part of the fraction has the name one fourth.

Fraction in words- Fraction name of each part in words is one fourth.

Fraction in number- Fraction of each part in number is 1/4.

Thus, Fraction name of each part in words is one fourth and Fraction of each part in number is 1/4.

Idk this answer because no triangles are shaded.

Express the following as a function of a single angle.
Cos^2(81°) - sin^2(81°)

Answers

Answer:

= $Cos$ (162°)

Step-by-step explanation:

$Cos^(2)$ (81°) - $Sin^(2)$ (81°)

we know that;

$Cos^(2)$ (x°) - $Sin^(2)$ (x°) = $Cos$ (2x°)

$Cos^(2)$ (81°) - $Sin^(2)$ (81°) = $Cos$ (2 * 81°)

= $Cos$ (162°)

Mrs. Lin bin 6 hamburger buns to the barbecue. 2/3 of the trays have wheat buns. How many of the trays have wheat buns? Draw a diagram to solve the problem

Answers

I don’t know how to draw a diagram for this problem but I think you just did divide

4 trays have wheat buns

draw 6 rectangles and divide each by 3 then shade 2 parts of each (if there is a blank section in any of the "trays" but count it as a new shaded part) then count all the trays that are fully shaded
