Answer:

Step-by-step explanation:

$(a^{m})^{n}=a^{m*n}\\\\a^{m}*a^{n}=a^{m+n}\\\\a^{-m}=\frac{1}{a^{m}}\\\\\\(6n^{-5})(3n^{-3})^{2}=(6n^{-5})*3^{2}*n^{-3*2}\\\\=6n^{-5}*9*n^{-6}\\\\=6*9*n^{-5 +(-6)}\\\\=54n^{-11}\\\\=\frac{54}{n^{11}}$

Answer:

Step-by-step explanation:

What we know:

ABD is a straight angle, it measures 180 degrees
Angle CBA + CBD = 180 degrees
Angle GFH = CBA (they are alternate exterior angles)

Equation:

GFH + CBD = 180

Substitute:

3x + 6x = 180

Add:

3x + 6x = 180

9x = 180

Divide:

9x = 180

/9 /9

x = 20

Substitute:

GFH = 3x

GFH = 3(20)

GFH = 60

m<GFH is 60°

Answer:

(a) Percentage of girls = 55 $\frac{5}{7}$

(b) Percentage of boys = 44 $\frac{2}{7}$

Step-by-step explanation:

To find percentage, we multiply the fraction out of the total by 100%.

Percentage of girls = $\frac{780}{1400}$ × 100%

= 55 $\frac{5}{7}$

Percentage of boys = $\frac{1400-780}{1400}$ × 100%

= 44 $\frac{2}{7}$

On a coordinate plane, triangle R S T has points (negative 5, 6), (3, 4), and (negative 2, 2). Which expression can be used to f

The area of a triangle is the amount of space on the triangle

The expression that represents the area of the triangle is $A = \frac 12|-5(2 -4) +3(2 -6) -2(4 -6)|$

The coordinates of the triangle are given as:

$R = (-5,6)$

$S = (3,4)$

$T = (-2,2)$

The area (A) of a triangle from its coordinates or vertices are:

$A = \frac 12|x_1(y_3 -y_2) +x_2(y_3 -y_1) + x_3(y_2 -y_1)|$

Substitute values for x's and y's

$A = \frac 12|-5(2 -4) +3(2 -6) -2(4 -6)|$

Hence, the expression that represents the area of the triangle is $A = \frac 12|-5(2 -4) +3(2 -6) -2(4 -6)|$
