Shawn wants to model the number 13,450 using base-ten blocks. how many large cubes, flats, and longs does he need to model the n

enot [183]

1 rod or long is a column of 10 unit cubes.

10 longs placed side by side, form a flat (with dimensions 10×10)

10 flats, placed on top of each other form a large cube, with dimensions 10×10×10 = 1000 cubes.
-------------------------------------------------------------------------------------------------

each small cube (unit cube) represents the number 1.

thus each long represents 10
each flat represents 100

and each large cube represents 1,000

The number 13,450 can be written as

1*10,000+3*1000+4*100+5*10 using the expanded form.

This means that there are 13 large cubes, 4 flats and 5 longs needed to model the number.

Answer: 13 large cubes, 4 flats, 5 longs

What is the minimum product of two numbers whose difference is 36? What are the numbers?

GalinKa [24]

Is suppose 36 and 0 would be the best.
36 - 0 = 36
36 x 0 = 0
Seems like that’s the answer

Solve for x. <br><br> 45(15x+20)−7x=56(12x−24)+6

Liula [17]

Greetings!

Solve for x.
$45(15x+20)-7x=56(12x-24)+6$
Distribute the Parenthesis.
$675x+900-7x=56(12x-24)+6$
$675x+900-7x=672x-1344+6$
Combine Like Terms.
$668x+900=672x-1338$
Add 1338 to both sides.
$(668x+900)+1338=(672x-1338)+1338$
Subtract 668x from both sides.
$[(668x+900)+1338]-668x=[(672x-1338)+1338]-668x$
Simplify.
$900+1338=672x-668x$
$2238=4x$
Divide both sides by 4.
$(2238)/4=(4x)/4$
Simplify.
$559.5=x$
$x=559.5$

Hope this helps.

A tank contains 100 kg of salt and 1000 L of water. A solution of a concentration 0.05 kg of salt per liter enters a tank at the

Umnica [9.8K]

Answer:

Step-by-step explanation:

Initial Quantity of salt Q(0) = 100 kg

Capacity of tank = 1000 L

Inflow of liquid = 10 l /minute and outflow = same rate thus leaving the content of volume 1000 L at any time

Assume after entering constantly mixes and drains out.

Concentration flow = inflow - outflow
