ritu can row downstream 20km in 2 hrs and upstream 4km in 2 hrs. find the speed of rowing in still water and the speed of the cu

Marina CMI [18]

Answer:

Speed of boat in still water is 6km/h

Speed of current is 4km/h

Step-by-step explanation:

We know speed = distance / time

Let the speed of boat in still water be x

Let the speed of current be y

Hence the speed of boat, down stream = $x+y$

Distance downstream = 20km

Time taken = 2 hours

We have

$x+y=\frac{20}{2}$

$x+y=10$ ......(1)

Speed of boat upstream = $x-y$

Distance upstream = 4

Time taken = 2

We have

$x-y=\frac{4}{2}$

$x-y=2$ ...(2)

Adding (1) & (2)

$2x=12$

$x=6$

Substituting in (1) we get

$y=4$

You purchase two bottles of sunscreen and a hat. The hat costs$6.50. you pay 6% sales tax. You pay a total of $16.43. How much d

Alik [6]

Solution:

Let the bottle of sunscreen cost be $x. Then we can write

($x+ $6.50)+6%($x+ $6.50)=$16.43

Now solve this for x as below

$($x+ $6.50)+\frac{6}{100}($x+ $6.50)=$16.43\\$

$\frac{100x+650+6x+39}{100}=16.43\\
\\
106x+689=1643\\
\\
106x=1643-689\\
\\
106x= 954\\
\\
x=9\\$

Hence the bottle of sunscreen cost $9.

zzz [600]

Answer:

A rice cooker, also known as a rice steamer, is a popular small appliance that works like a slow cooker by using moist heat to cook food while trapping the flavors in the pot until it’s ready to enjoy. Modern rice pressure cookers significantly reduce rice-making time and often feature a warming setting so you can be flexible with meal times.
