Let
z-----------> t<span>he height of the larger box
x-----------> the length side of the box (smaller and larger box)
y-----------> t</span>he width side of the box (smaller and larger box)<span>
volume larger box=x*y*z
</span>volume smaller box=x*y*(0.80z)----> 0.80[x*y*z]
the difference in the volume of these two boxes=[x*y*z]*(1-0.80)
the difference in the volume of these two boxes=0.20*[x*y*z]
<span>The height of the smaller box is 12 in
</span>so
z*0.8=12--------> z=12/0.8---------> z=15 in
x=7 3/4 in--------> (7*4+3)/4---------> 31/4 in
y= 2 in
the difference in the volume of these two boxes=0.20*[(31/4)*2*15]
the difference in the volume of these two boxes=46.5 in³
the answer is
46.5 in³
Answer:
TOTAL TAX IS: $19.25
TOTAL PRICE IS: $294.25
MONEY LEFT IS: $135.75
Step-by-step explanation:
First, you do a proportion:
?/275 = 7/100
the ?/275 represents how much money in $275
the 7/100 represents 7% (7 hundredths)
then you cross multiply:
275 x 7 = 1925
then you divide:
1925 divided by 100 = 19.25
<em><u>So $19.25 is the tax amount.</u></em>
<em><u></u></em>
To get the total price, you add:
Tax ($19.25) + Cost($275) = $294.25
<u><em>$294.25 is the total amount that Anna has to pay.</em></u>
<u><em></em></u>
To get what Anna has left over, you subtract:
Has($430) - Spend($294.25) = $135.75
<u><em>Anna has $135.75 left.</em></u>
<u><em></em></u>
I hope this helped you a lot!

Answer:
3 water bottles
Step-by-step explanation:
25-10=15
15/5=3
x² + 10x = 26
x² + 10x + 25 = 26 + 25
x² + 5x + 5x + 25 = 51
x(x) + x(5) + 5(x) + 5(5) = 51
x(x + 5) + 5(x + 5) = 51
(x + 5)(x + 5) = 51
(x + 5)² = 51
x + 5 = ±√(51)
- 5 - 5
x = -5 ± √(51)
x = -5 + √(51) or x = -5 - √(51)
