Answer:
1448 Pounds per truck
Step-by-step explanation:
Divide 2896 by 2
If you haven't learned long division yet, try breaking up the number and dividing it by 2 like this:
2000/2=1000
800/2=400
90/2=45
6/2=3
Then, add them up and solve from there: 1000+400+45+3=1400+48=1448
Let x be the amount of pure water (in mL) you need to add. The new mixture would have a total volume of 80+x mL. The solution you have contributes 0.95 mL of alcohol for each mL of solution, so that it currently contains 0.95*80 = 76 mL of alcohol. You want to the new mixture to have a concentration of 10%, so that
76 / (80 + x) = 0.1
==> 76 = 0.1(80 + x) = 8 + 0.1x
==> 68 = 0.1x
==> x = 680 mL
"I am a figure with six layers .each of my layers is the same."---> using this sentences, you can conclude that the shape is cube because cube made of 6 similar square.
<span>my bottom layer has a perimeter of 28 units ---> Using this sentences, you can know the square perimeter is 28. Then the square side would be:
square perimeter= 4* side
28= 4* sides
side= 7
Then, the volume of the cube would be:
cube volume= side^3
cube volume= 7^3= 343 cubic units
I think there is a typo somewhere in this question. The calculation should be true, but it is not in 200-300 range. The volume that in 200-300 would be when the side is 6 unit(volume=216), but the perimeter should be 24 not 28.
If the perimeter 28, volume= </span>343 <span>
If the perimeter 24, volume= 216</span>
