3/4

Step-by-step explanation:

Jessica shaded 6/8 of the circle. That fraction can be reduced by removing a factor of 2 from numerator and denominator. The reduced fraction is 3/4.

$\dfrac{6}{8}=\dfrac{2\cdot 3}{2\cdot 4}=\dfrac{2}{2}\cdot\dfrac{3}{4}=1\cdot\dfrac{3}{4}\\\\=\dfrac{3}{4}$

The equation for decibels and sound intensity is D=10log(sub 10) I/I(sub0) where D is decibels.

velikii [3]

$D=10\log\dfrac{I}{I_0}\\\\
D=10\log\dfrac{10^{11}}{10^{-12}}\\
D=10\log10^{23}\\
D=10\cdot23=\\
D=230$

A box is to be constructed with a rectangular base and a height of h cm. The length, l, of the box is 10 cm, and the width, w, i

Svetradugi [14.3K]

<span>The formula for the volume of a box is: Volume = L*W*H We know that the length is 10 cm. We know that the width is twice the height, so W = 2H. Then our volume equation is: Volume = 10*2H*H Volume = 20*H^2 Since H^2 is in the equation, this is a quadratic equation.</span>

755 = 65x + 40

715 = 65x

x = 11

x+4 = 15

2x = 22
