The best thing to do is to find out what 1/5 is equal to, and you can do this by dividing $13.32 by 3
13.32/3= 4.44
Therefore, 1/5 = $4.44
As you're looking for the total amount, you multiply this by 5.
$4.44*5= $22.20
Therefore, the present cost $22.20
Hope this helps :)

Plastic edging for flower beds comes in 50-foot rolls and costs $6.85 per roll. What is the cost to completely edge two rectangu

Klio2033 [76]

Answer:

The cost of edging the flower beds with roll is $41.10.

Step-by-step explanation:

Given,

dimension of rectangular flower bed :

length = 40 ft

width = 15 ft

dimension of circular flower bed :

diameter = 16 ft

cost of each roll = $6.85

We need to find the cost of roll used to cover completely rectangular and circular flower bed.

Solution,

Firstly we will find out the perimeter of the rectangular flower bed.

Since we know that the perimeter of rectangle is equal to twice the sum of its length and width.

framing in equation form, we get;

Perimeter = $2(40+15)=2\times55=110\ ft$

So the perimeter of 2 flower bed = $2\times110 =220\ ft$

Again we will find out the circumference of the circular flower bed.

And we know that the circumference of the circle is equal to pi multiplied with the diameter.

framing in equation form, we get;

Circumference = $\pi\times16=50.24\ ft$

Now the total edge for covering is equal to the sum of the perimeter of two flowerbed and circumference of one circular flower bed.

Total edge = $220+50.24=270.24\ ft$

Here also given that Plastic edging for flower beds comes in 50-foot per roll.

So we will find out the number of rolls required for edging.

For this we will use the unitary method.

50 ft = 1 roll

270.24 ft = number of roll

$\therefore number\ of\ rolls = \frac{270.24}{50}=5.40$

so we can say that there will be 6 rolls required for edging.

also given the cost of 1 roll is $6.85.

So the cost of 6 rolls = $6\times6.85=\$41.10$

Hence The cost of edging the flower beds with roll is $41.10.

A fireman's water hose shoots 320 kg of water each second against the door of a building. The velocity of the water is 20 m/s an

NeX [460]

Answer:

$6400\ \text{N}$

Step-by-step explanation:

$\dfrac{m}{t}$ = Mass flow rate of water = 320 kg/s

$m$ = Mass of water on the door

$t$ = Time

$v$ = Velocity of water on the door = 20 m/s

Force is given by

$F=\dfrac{m}{t}v\\\Rightarrow F=320\times 20\\\Rightarrow F=6400\ \text{N}$

The average force is exerted by the stream of water is $6400\ \text{N}$ .
