Answer:

11) x = 9

12) x = 9

Step-by-step explanation:

11) Corresponding segments are proportional, so ...

x/6 = 12/8

x = 6(12)/8 . . . multiply by 6

x = 9

12) Similar triangle relationships show you the geometric mean relationship that applies in this case.

long side/short side = x/3 = 27/x

x² = 3·27 . . . . . . cross multiply

x = √(3·27) . . . . geometric mean relationship

x = 9

Answer:

Step-by-step explanation:

The equation of the circumference of a circle is 2(pi)r

This is actually because 2pi is angle of the arc that makes up the full circle (radians of course)

so a simple formula is:

arc length in radians X radius

radius = 4 cm

the area that the question wants is the oposite

of the 142 degree section so 360 - 142 = 218

218 degrees * (pi/180) = 3.80482 rad

3.80482 * 4 = 15.21928 cm

An empty box is shaped like a rectangular prism. The box has a base area of 9/10 square foot and a height of 1/3 foot. How much

Ymorist [56]

Since we already know the base area, we simply have to multiply it by the height to get the volume of the box (how much packing material it can contain)

9/10 x 1/3

9 x 1 = 3
10 3 10 (I cancelled the 9 and 3 and made them 3 and 1 respectively)
The answer is 3/10 ft³
