Wal-Mart buys paper plates for $3.25 and marks them up for 142%. How much do I buy them for?

faltersainse [42]

Multiply the price by the percentage:

3.25 x 142% = 3.25 x 1.42 = 4.62

You pay $4.62

PLEASE HELP!!! Two towns are 1100 miles apart. A group of hikers starts from each town and walks down the trail toward each othe

Vinvika [58]

Answer:

2.54 miles/hr

2.04 miles/hr

Step-by-step explanation:

Given: Distance between the two towns = 1100 miles

Difference between speeds = $\frac{1}{2}$ miles/hr

Total time when they meet = 240 hours

To find:

Let distance traveled by first group = $x$ miles.

Now, the distance traveled by second group = (1100- $x$ ) miles/hr

The relation between Speed, Time and Distance is given as:

$\text{Speed =} \dfrac{\text{Distance}}{\text{Time}}$

Let speed of first group = $S_1$

$S_1 = \dfrac{x}{240}$

Let speed of second group = $S_2$

$S_2 = \dfrac{1100-x}{240}$

As per question, $S_1$ = $S_2$ + $\frac{1}{2}$

$\dfrac{x}{240} = \dfrac{1100-x}{240} + \dfrac{1}{2}\\\Rightarrow \dfrac{x}{240} - \dfrac{1100-x}{240} = \dfrac{1}{2}\\\Rightarrow \dfrac{x-1100+x}{240} = \dfrac{1}{2}\\\Rightarrow 2x - 1100 = 120\\\Rightarrow 2x = 1220\\\Rightarrow x = 610 ft$

Now,

$S_1 = \dfrac{x}{240}$

Putting value of $x$ :

$S_1 = \dfrac{610}{240}\\\Rightarrow S_1 = 2.54\ miles/hr$

Similarly, putting value of $x$ in $S_2$ :

$S_2 = \dfrac{1100-610}{240}\\\Rightarrow S_2=\dfrac{490}{240}\\\Rightarrow S_2 = 2.04\ miles/hr$

What is the approximate length of ? Use the law of sines to find the answer.

aniked [119]

Sine (Angle K) / side k = sine (105) / 4.7
Sine Angle K = (2.7 * 0.96593) / 4.7
Sine Angle K = 0.5548959574 
Angle K = 33.704 degrees
Angle J = 180 -105 -33.704 = 41.296
Sine J / side (j) = sine (105) / 4.7
Sine (41.296) / side (j) = 0.96593 / 4.7
Side (j) = Sine (41.296) / 0.96593 / 4.7
Side (j) = 0.65995 / 0.2055170213 
Side (j) = 3.21117
