Rounded to the nearest dime ,what is the greatest amount of money that rounds to $105.40?What is the least amount of money that

victus00 [196]

$100.00 rounded value
$105.00 rounded value
$110.00 rounded value

For example,
14,494 
To round off the height value to the nearest thousand we can use the expanded from to clarity the position of numbers which is: 
10, 000 = ten thousand 
4, 000 = thousands 
400 = hundreds 
90 = tens 
4 = ones 
Here we can notice than four thousand is the value where the nearest thousands is placed. Hence we can round off the number of 14, 494 into 14, 000. Notice 0-4 rounding off rules.

Suppose you inherited a house that was purchased in 1950 for 20,000. It is now 2015 and the value of the house has increased by

Masja [62]

Answer:

I think the house would now costs $85,000

Step-by-step explanation:

First, I multiplied by how many years between 1950 to 2015 and 5 to get 325.

Next, I divided 20,000 by 100 to get 200 to find 1% of 20,000.

Then, I multiplied 325 by 200 to get 65,000

Finally, I added 20,000 to 65,000 to get 85,000

So, I guess/answer is $85,000

If I was wrong, then just say, "Sorry, but that was incorrect."

how many kilograms of pure water is to be added to 100 kilograms of a 30% saline solution to make it a 10% saline solution

Irina-Kira [14]

Answer:

200 kg

Step-by-step explanation:

If w is the amount of water added, then the concentration of the solution is ...

salt/solute = 100(0.30)/(100 +w) = 0.10

30 = 10 +0.10w . . . . . simplify

20 = 0.10w . . . . . . . . subtract 10

20/0.10 = w = 200 . . . . divide by 0.10

200 kg of water must be added to dilute the solution to 10%.

Need help vrtfv fvvfgsf

maksim [4K]

Answer:

b = 8

Step-by-step explanation:

Use the Pythagorean theorem

c^2 = a^2 + b^2

c = 10

a = 6

b = ?

Substitute into the formula

10^2 = 6^2 + b^2

100 = 36 + b^2 Subtract 36 from both sides

100 - 36 = b^2 Combine

64 = b^2 Take the square root of both sides.

√64 = √b^2

b = 8
