165.63-$18.99= $146.64

$146.64 / .78€ per mi= 188miles

188 miles is your answer

tester [92]
Let w be the width of the deck. Then, using the total area, we get:
(9+2w)(18+2w)=400
4w²+54w-238=0
2w²+27w-119=0
(2w-7)(w+17)=0
w=-17 or 7/2
Using the positive value, we get a width of 3&1/2 ft. for the deck

Ms.Lamberson got a new puppy abd weighed it in September and October in September the Puppy Weighed9 and one Fourth pounds In Oc
ddd [48]

Answer: The puppy was 2.25\ lb havier in October that it was in September.

Step-by-step explanation:

You need to make the conversion from mixed numbers to decimal numbers. To do it, divide the numerator of the fraction by the denominator add the result to whole part number:

9\frac{1}{4}=9+0.25=9.25\\\\11\frac{1}{2}=11+0.5=11.5

The weight of the puppy in September was:

w_1=9.25\ lb

And its weight in October was:

w_2=11.5\ lb

Subtract its weight in September from its weight in October in order to find how much heavier the puppy was in October than it was in September:

w_2-w_1=11.5\ lb-9.25\ lb=2.25\ lb

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}
