Answer:

$2 \frac{1}{5} + 1 \frac{5}{6} = 2 \frac{6}{30} + 1 \frac{25}{30} \\ \\ \frac{66}{30} + \frac{55}{30} = \frac{121}{30} \\ \\ \\ = 4 \frac{1}{30}$

Suzanne wants to put a fence around her square garden. If the garden covers an area of 49ft^2, how many feet of fencing does she

lina2011 [118]

Answer:

The area for a square is given by:

$A = x^2$

And we can find the dimension for one side like this:

$x = \sqrt{A}$

Replacing we got:

$x = \sqrt{49 ft^2}= 7ft$

Then since we are interested in the how many feet of fencing does she need, we can find the perimeter given by:

$P = 4x$ and replacing we got:

$P = 4*7 ft = 28 ft$

Step-by-step explanation:

For this case we know that Suzanne want to put a fance around a square garden with an area of 49 ft^2

The area for a square is given by:

$A = x^2$

And we can find the dimension for one side like this:

$x = \sqrt{A}$

Replacing we got:

$x = \sqrt{49 ft^2}= 7ft$

Then since we are interested in the how many feet of fencing does she need, we can find the perimeter given by:

$P = 4x$ and replacing we got:

$P = 4*7 ft = 28 ft$

A car is driving at 100 kilometers per hour. How far, in meters, does it travel in 3 seconds?

dlinn [17]

Answer:

The car travels 83 1/3 meters in 3 seconds.

Step-by-step explanation:

Speed of car = 100 KM/ hour

1 km= 1000m

1 hour = 3600 seconds

Lets find speed of car in Meters/second

speed of car in m/sec = 100*1000 m/3600 second

here we have taken 1000 for km and 3600 for hour

speed of car in m/sec = 100*1000 m/3600 second = 500/18 m/second

speed of car in m/sec = 250/9 m per sec

We know that

distance = speed*time

speed = 250/9 m per sec

time =3 second

distance = 250/9 * 3 meters = 250/3 meters = 83 1/3 meters.

Thus, car travels 83 1/3 meters in 3 seconds.
