lidiya [134]

Using proportions, it is found that 66 people in the survey worked on election day.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

For this problem, the amounts of people who worked are:

64% of 50(voted).

40% of 85(did not vote).

Hence the total amount is given by:

0.64 x 50 + 0.4 x 85 = 66.

66 people in the survey worked on election day.

If a sphere of ice cream that was 2.5 inches in diameter was placed on top of the ice cream cone that had a height of 4 inches a

liq [111]

Answer:

The cone would not the all of the ice cream fit into the cone.

Step-by-step explanation:

Geometrically speaking, the volume of the cone ( $V_{c}$ ), measured in cubic inches, is described by the following equation:

$V_{c} = \frac{\pi}{3}\cdot r^{2}\cdot h$ (1)

Where:

$r$ - Base radius, measured in inches.

$h$ - Height, measured in inches.

And the ice cream ball is described by the volume equation for the sphere ( $V_{s}$ ), measured in cubic inches:

$V_{s} = \frac{4\pi}{3} \cdot R^{3}$ (2)

Where $R$ is the radius of the ice cream ball, measured in inches.

In this case, the ice cream will fit into the cone if and only if $V_{s} \le V_{c}$ . That is:

$\frac{4\pi}{3}\cdot R^{3} \le \frac{\pi}{3}\cdot r^{2}\cdot h$

$4\cdot R^{3} \le r^{2}\cdot h$

If we know that $r = 0.875\,in$ , $h = 4\,in$ and $R = 1.25\,in$ , then the inequation is:

$4\cdot (1.25\,in)^{3}\le (0.875\,in)^{2}\cdot (4\,in)$

$6.25\,in^{3}\le 3.063\,in^{3}$ (CRASH!)

Which leads to an absurd. Hence, the cone would not the all of the ice cream fit into the cone.
