A tennis ball has a diameter of 2.7 inches. The tennis coach wants to fill her storage shed with tennis balls. If the storage sh
Oksanka [162]

Given that,

The diameter of a tennis ball, d = 2.7 inches

Radius, r = 1.35 inches

The dimensions of the storage shed is 14 feet wide, 15 feet long, and 10 feet high.

Volume of the shed is, V = lbh

V=14\times 15\times 10\\\\V=2100\ \text{feet}^3

We can convert radius from inches to feet :

1 foot = 12 inches

Radius, r = 0.1125 feet

Let there are x number of tennis balls that can fit in the shed. So,

x\times V_b=V_s\\\\\text{Where}\ V_b\ \text{and}\ V_s\ \text{volume of ball and shed}\\\\x=\dfrac{V_s}{\dfrac{4}{3}\pi r^3}\\\\x=\dfrac{2100}{\dfrac{4}{3}\pi \times (0.1125)^3}

x = 352105.75 balls

or

x = 352106 balls

Hence, 352106 balls can fit in the storage shed.

Line L has an undefined slope. Line M is perpendicular to line L. Which of the following could be the equation of line M?
Marat540 [252]
"Line L has an undefined slope" so line L is any vertical line. 

Anything perpendicular to this vertical line will be horizontal. So line M is horizontal. 

Horizontal lines are of the form y = k for some fixed number k. The only thing that fits is choice B) y = 7 where k = 7 in this case.

Choice A graphs out a diagonal line, choice C graphs a vertical line, while choice D graphs out a hyperbola. These facts are why we can eliminate these non-answers. 

Answer: Choice B) y = 7
