When p = 12, t = 2, and s = One-sixth, r = 18. If r varies directly with p and inversely with the product of s and t, what is th
bagirrra123 [75]

Answer:

k = \frac{1}{2}

Step-by-step explanation:

Given

p = 12

t = 2

s = \frac{1}{6}

r = 18

r\ \alpha\ p\ * \frac{1}{s * t}

Required

Find the constant of variation

From the question, the variation is as follows

r\ \alpha\ p\ * \frac{1}{s * t}

r\ \alpha\ \frac{p * 1}{s * t}

r\ \alpha\ \frac{p}{s * t}

Convert variation to equation

r\ = k\frac{p}{s * t}

Where k represents the constant of variation

Make k the subject of formula;

Multiply both sides by s * t

r * s * t = k\frac{p}{s * t} * s * t

r * s * t = kp

Divide both sides by p

\frac{r * s * t}{p} = \frac{kp}{p}

\frac{r * s * t}{p} = k

k = \frac{r * s * t}{p}

Substitute the values of p, r, s and t in the above equation

k = \frac{18 * \frac{1}{6} * 2}{12}

k = \frac{6}{12}

Divide numerator and denominator by 6

k = \frac{1}{2}

Hence, the constant of variation is; k = \frac{1}{2}

Find all real numbers x such that 4x-18&gt;2 and -17x-8<img src="https://tex.z-dn.net/?f=%20%5Cleq%20" id="TexFormula1" title="
NISA [10]
With the given inequalities, the best answer is the middle graph. Getting the values for x, we obtain x>5 and x>=1. The middle graph shows that the value of x is all real numbers greater than or equal to 5. This best satisfies both equation as the two values for x requires real number greater than 5 and greater than or equal to 1 respectively.

Meg skateboards One-fourth of a mile in One-half of an hour. At this rate, how far will she skateboard in an hour? StartFraction
kiruha [24]

Answer:

1/2 Mile In 1 Hr. or 0.5 MPH

Step-by-step explanation:

Since we know 1/4 is in 30x

1 hr = 60x

1/4 = 30x and we're looking for 60x -->

Simply we multiply 1/4 by 2 giving us 2/4

--> simplify and we have 1/2

Final: 1/2

<u><em>Hope this helps!</em></u>
