Answer:

3.5 * 6.7 = 23.45

Step-by-step explanation:

(I am assuming you know how to do 2-digit by 2-digit problem, but just in case you don't I am putting in how to do it.)

You would multiply the problem like a normal 2-digit by 2-digit problem.

- multiply the ones places (5*7=35)

- you bring the 3 of the 35 and put it above the other 3

- you then do 7*3=21+3 because you moved it.

-so the first part of the question would be 35*7=245

-you go below the 5 and put a zero because you dont need the ones place anymore.

-you then do the same thing but with the tens place instead.

- You would then get 35*6=210, but you can't forget the zero.

- you would then add 245+2100=2,345

- But don't forget the decimals. you have to add the decimals to the answer.

- you count how many numbers that are behing both numbers, in this case it would be two.

- you then put the decimal after the ones and tens place.

Answer:

The number of chicken and cows should be 19 and 11.

Step-by-step explanation:

The number of chicken and cows should be 19 and 11.

Given that,

The farm has 30 chickens and cows, and there are 82 chicken and cow legs all together.

Let x represent the number of chickens in the farm.

Let y represent the number of cows in the farm.

Based on the above information, the calculation is as follows:

x + y = 30

Since a chicken has 2 legs and a cow has 4 legs.

So,

2x + 4y = 82 - - - - - - - - - - - - 1

Now

Substituting x = 30 - y into equation 1, it becomes

2(30 - y) + 4y = 82

60 - 2y + 4y = 82

- 2y + 4y = 82 - 60

2y = 22

y = 11

Now

x = 30 - 11

= 19

One cubic meter of water weighs approximately 2200 pounds. There are 100 cm in one meter. If you have a box-shaped fish tank tha

Diano4ka-milaya [45]

Answer:

158.4 pounds

Step-by-step explanation:

first find the volume of the tank

$V = 30 \times 30 \times 80$

$V = 72000 cm^3$

to convert this to m^3 we know that 1m = 100cm

$V = 72000 cm^3 \times \left(\dfrac{1\,\text{m}}{100\,\text{cm}}\right)^3$

$V = 72000 cm^3 \times \left(\dfrac{1\,\text{m}^3}{100^3\,\text{cm}^3}\right)$

the cm^3 cancel out.

$V = \dfrac{72000}{100^3} m^3$

$V = 0.072\,m^3$

by simply converting the side-lengths to meters beforehand can give you this answer directly:

$V = 0.3 \times 0.3 \times 0.8 = 0.072 m^3$

it is given that 1 meter cube of water weighs about 2200 pounds.

$1\,m^3 = 2200 \,\text{lb}$

multiply both sides with 0.072 to find our answer:

$1\,m^3 \times 0.072 = 2200 \times 0.072 \,\text{lb}$

$0.072\,m^3 = 158.4 \,\text{lb}$

hence the weight of the water in the tank would be 158.4 pounds!
