What is the length of side BC? What is the length of side GH?

almond37 [142]

In this situation you would have to use ratios to figure it out.
AD over EH or 24/16 that would be equal to 1.5
This would show that BC over GF is also equal to 1.5.
6/4 is equal to 1.5.
Side length BC is 6

I don’t know how to solve this

Romashka-Z-Leto [24]

Answer:

see explanation

Step-by-step explanation:

The perimeter is the length of all the sides in the figure.

The arc of the semi- circle is included in this.

length of arc = $\frac{1}{2}$ πd ← d is the diameter

here d = 8, hence

arc = $\frac{1}{2}$ π × 8 = 4π ← exact length

Perimeter = 10 + 8 + 10 + 4π ≈ 40.57 in ( nearest hundredth )

Simplify (-3c^-3w^5)^3<br> A -9w^8<br> B. -27cw^8<br> C. w^15/27c^9<br> D.-27w^15/c^9

kenny6666 [7]

Answer:

$\large\boxed{D.\ \dfrac{-27w^{15}}{c^9}}$

Step-by-step explanation:

$(-3c^{-3}w^5)^3\qquad\text{use}\ (ab)^n=a^nb^n\\\\=(-3)^3(c^{-3})^3(w^5)^3\qquad\text{use}\ (a^n)^m=a^{nm}\\\\=-27c^{-3\cdot3}w^{5\cdot3}=-27c^{-9}w^{15}\qquad\text{use}\ a^{-n}=\dfrac{1}{a^n}\\\\=-27\left(\dfrac{1}{c^9}\right)w^{15}=\dfrac{-27w^{15}}{c^9}$
