Answer:

Weight of wastage=179.775kg

weight of rice cultivated= 585.225 kg

percentage of rice cultivated=76.5%

Step-by-step explanation:

Area of land=100 square meters

Cultivated rice=765kg

Wastage=23.5%

1) Weight of the wastage=23.5% of 765kg

=23.5/100 × 765

=17977.5 / 100

=179.775 kg

2) Weight and percentage of rice cultivated.

weight of rice cultivated = 765 kg - 179. 775 kg

= 585.225 kg

percentage of rice cultivated = 100 - 23.5

= 76.5%

3) if area is increased 40 times in size

New area=1000 square meters × 40

=40,000 square meters

Cultivated rice= 765kg × 40

=30,600 kg

Cultivated rice excluding wastage=585.225 kg × 40

=23,409 kg

It takes the hot water faucet twice as long to fill a bathtub as it does the cold water faucet. Left on together, the cold and h
Lerok [7]

Answer:

Step-by-step explanation:

Make a system of equations

Give the hot and cold faucets variables

Set x to be the minutes it takes for the hot water faucet to fill up the tub and Set y to be the minutes it takes for the cold water faucet to fill up the tub

She first equation is x = 2y because the hot faucet takes <em>2 times</em> as much time as the cold water

The second equation is x + y = 5 because if you add the number of minutes each takes to fill a tub, it will add up to 5 minutes

Now you have the equations

x = 2y

x + y = 5

So you can plug the first equation in for x in the second one to make

2y + y = 5

which equals 3y = 5

Then you divide 3 from both sides to get

y = \frac{5}{3}

Since y is the number of minutes the cold water faucet takes to fill the tub, then the cold faucet takes \frac{5}{3} minutes for the cold water faucet to fill the tub itself

3 less than 16 divided by a number s is 5
ohaa [14]
3-16/a= 5
subtract 3-16
-13/a=5
multiply both sides by a
-13=5a
flip the equation
5a= -13
divide both sides by 5
a= -2.6

check the equation
3-16/-2.6=5
-13/-2.6=5
5=5
