The cool cold drink shop bought a batch of juice drinks for 864 yuan. 1. 24 bottles in each box. How much is each bottle?

The cool cold drink shop bought a batch of juice drinks for 864 yuan. 1. 24 bottles in each box. How much is each bottle?

How many boxes? 864 divided by 24N for n boxes
One carton is 864 divided by 24, two cartons is 864 divided by (24 times 2)
In the equal ratio sequence {an}, if A3 and A7 are two of the equations 3x2-11x + 9 = 0, then the value of A5 is ()
A. 3B. ±3C. 3D. ±3
∵ A3 and A7 are two parts of the equation 3x2-11x + 9 = 0 ∵ a3a7 = 3 & nbsp; A3 + A7 = 113 ∵ 0 ∵ a3a7 = a25, A3 + A7 = 113 ∵ 0 ∵ A5 = 3, so C is selected
Abcdefghik is known to represent 10 distinct natural numbers greater than zero. C plus B equals a, D plus e equals B, E plus f equals C, G plus h equals D, and H plus I
If e, I plus k equals F, then what is the minimum of a?
C plus B equals a, D plus e equals B, E plus f equals C, G plus h equals D, H plus I equals e, I plus k equals F
A=H+I+I+K+G+H+H+I
So make a minimum
Then H = 1, I = 2, k = 3, g = 4
A=3+6+3+4=16
Twenty
Why does a box of drinks need 12 or 24 bottles
1. Easy to count, Westerners used to dozen, that is, "hit" calculation
2. The package is suitable for transportation. If the length and width difference is large, it is unstable. If it is the same (such as 4 bottles and 9 bottles), the upper and lower layers are not pressed and easy to fall
3. In fact, there are 6 bottles of packaging:)
Given that {an} is an equal ratio sequence, and A4 + A7 = 2, a5a6 = - 8, then a1 + A10 = ()
A. 5B. -5C. 7D. -7
∵ A4 + A7 = 2, according to the properties of the equal ratio sequence, a5a6 = a4a7 = - 8 ∵ A4 = 4, a7 = - 2 or A4 = - 2, a7 = 4. When A4 = 4, a7 = - 2, Q3 = - 12, ∵ A1 = - 8, A10 = 1, ∵ a1 + A10 = - 7. When A4 = - 2, a7 = 4, Q3 = - 2, then A10 = - 8, A1 = 1 ∵ a1 + A10 = - 7. In conclusion, a1 + A10 = - 7 is selected as D
We know that a is not equal to 0, and a * 5 / 3 = b * 4 / 3 = C / 10 / 9 = D * 125% = e * 5 / 6, then the largest number of a, B, C, D, e is () and the smallest number is ()
Because 5 / 6A
So the biggest one is e and the smallest one is a
The rule of cold drink shop is: five empty soda bottles can be exchanged for one bottle of soda. A class of students drank 161 bottles of soda, some of which were exchanged with empty bottles left over. So, how many bottles of soda should they buy at least?
According to the stem analysis, you can get (1 + 14) bottles of soda when you buy a bottle of soda, 161 ÷ (1 + 14), = 161 × 45, = 128.8, ≈ 129 (bottles). A: they need to buy at least 129 bottles
Given that {an} is an equal ratio sequence, and A4 + A7 = 2, a5a6 = - 8, then a1 + A10 = ()
A. 5B. -5C. 7D. -7
∵ A4 + A7 = 2, according to the properties of the equal ratio sequence, a5a6 = a4a7 = - 8 ∵ A4 = 4, a7 = - 2 or A4 = - 2, a7 = 4. When A4 = 4, a7 = - 2, Q3 = - 12, ∵ A1 = - 8, A10 = 1, ∵ a1 + A10 = - 7. When A4 = - 2, a7 = 4, Q3 = - 2, then A10 = - 8, A1 = 1 ∵ a1 + A10 = - 7. In conclusion, a1 + A10 = - 7 is selected as D
1.25 * a = B △ 3 / 4 = C △ 1 / 5 = D * 9 / 10, and a, B, C, D are not equal to 0
nothing
The answer is: b > d > a > C
It's a process
Let 1.25 * a = B ／ 3 / 4 = C ／ 1 / 5 = D * 9 / 10 = X
It can be simplified
A=4X/5,B=4X/3,C=X/5,D=10X/9
therefore
：B＞D＞A＞C
It is known that the volume of a cylindrical beverage bottle is 500ml. When the bottle is placed upright, the height of the beverage in the bottle is 20cm. When the bottle is placed upside down, the beverage in the bottle is 5cm free
How much is the drink in the bottle
There is a drink in the bottle
=500÷（20+5）×20
=500÷25×20
=400 ml
Height of bottle: 20 + 5 = 25 (CM),
Bottom area: 500 △ 25 = 20 (square centimeter),
Beverage volume: 20x20 = 400 (cm3),
Volume: 400 CC = 400 ml.
A: there are 400 ml of drinks in the bottle.
Hope to adopt!
