The perimeter of a square is equal to four times the length of a side. Write the direct v variation equation that represents the

sveticcg [70]

Answer: $y=4x$

Step-by-step explanation:

A direct variation equation has the form:

$y=kx$

Where <em>k</em> is a constant.

By definition, we know that the perimeter of the square is the sum of the lengths of its sides or, as all the sides are equal, you can multiply the lenght of any side by 4.

Then, knowing that <em>y</em> is the dependent value and <em>x</em> the independent value and the constant <em>k=4, </em> you can write the following direct variation equation that represents the situation.

$y=4x$

Iodine-125 has a half-life of about 60 days.

andreyandreev [35.5K]

Since it has a half life of 60 days, this means that every 60 days it multiplies by 0.5. Since it asks for 300 days, your equation is 500*(0.5)^5, which is 15.625 mg left after 300 days.

Answer:

Answer in terms of π=144π m^3

Answer by replacing π with 3.14 is 452.16 approximately 452.2m^3

Answer to the nearest whole no. is 452m^3

Step-by-step explanation:

$volume \: of \: a \: cone = \frac{1}{3} \pi {r}^{2} h$

$radius = \frac{diametre}{2}$

$radius = 24$

$height = 18$

$slant \: height \: = 30$

$first \: step$

$the \: exact \: volume \: of \: the \: cone \: in \: terms \: of \: \pi$

$v = \frac{1}{3} \pi {r}^{2} h$

$\: \: = \frac{1}{3} \times \pi \times 24 \times 18$

$\: \: \: = \frac{432\pi}{3}$

$\: \: \: = 144\pi$

$second \: step$

$approximate \: answer \: using \: 3.14 \: in \: place \: of \: \pi$

$144 \times 3.14$

$= 452.16$

$approximately \: 452.2$

$last \: step$

$answer \: to \: the \: nearest \: whole \: number$

$452 {m}^{3}$
