The height, width and Lenght isn't Given. However, we can create an hypothetical scenario, with a height 6, length 8 and width 4
Answer:
192 unit³
Step-by-step explanation:
The volume of the card box :
Recall the volume of box formula :
V = length * width * height
Volume = 8 * 6 * 4
Volume = 192 unit³
This is the procedure for any given dimension of the card deck.

GRADE 7 MATH URGENT
A class of 25 children is having a pizza party. Each child will eat 3/8 of a pizza. How many pizzas do they need to order?
A. 8 pizza pies at 10 pc. per pie = 80 available pieces
B. Let X be the number of children. Number of pieces eaten = 5 per child = 5X.
c. 22 pieces are left over.
D. Combine line A and line C. Total number of pieces eaten = 80 original minus 22 left over. Result 58 pieces were eaten by X children: 58 = 5X.
E. Solve the equation 58 = 5X by dividing both sides by 5.
WHOOPS! Is this a trick question? Solving the above results in the answer that there are 11.6 children at the party. Hmmm. That 0.6 child is a question mark for me.
Looks like someone miscounted the pizza slices. Or omitted some pertinent information. But, I’m sure there is a logical answer.
Answer:
10 pizzas
Step-by-step explanation:
To find the answer for this question you need to multiply 3/8 by 25.
3/8 * 25 = 9.375
You can't buy .375 of a pizza so you round it up and get 10.
The value of a car decreases by 5% each year. Sophie bought a car two years ago for £10000. Work out the value now.
Given:
The value of car before two years = £10000
The value of the car decreases by 5% each year.
To find:
The present value of the car.
Solution:
The exponential decay model for present value is
[tex]y=a\left(1-\dfrac{r}{100}\right)^t[/tex]
Where, a is the initial value, r is the rate of decay and t is time in years.
Putting P=10000, r=5 and t 2, we get
[tex]y=10000\left(1-\dfrac{5}{100}\right)^2[/tex]
[tex]y=10000\left(1-0.05\right)^2[/tex]
[tex]y=10000\left(0.95\right)^2[/tex]
On further simplification, we get
[tex]y=10000(0.95)(0.95)[/tex]
[tex]y=9025[/tex]
Therefore, the present value of the car is £9025.

Find the geometric mean of 24 and 45.
The geometric mean of 24 and 45 is equal to 32.86.
Given the following data:
Numbers = 24 and 45.What is geometric mean?Geometric mean is an average value that is used to indicate the central tendency of a data set containing a group of numbers, especially by determining the product of their values.
Mathematically, geometric mean is given by this formula:
[tex]G=\sqrt[n]{x_1x_2...x_n}[/tex]
Substituting the given parameters into the formula, we have;
[tex]G = \sqrt[2]{24 \times 45} \\\\G = \sqrt{1080}[/tex]
G = 32.86.

Which expressions are equivalent to − 90 − 60 w?
Answer:
A : -30(3+2w)
B : (-9-6w) ⋅ 10
E : −20(4.5 + 3w)
Using distributive property:
A : -30(3+2w) = -90 - 60w : equivalent to -90 - 60w
B : (-9-6w) ⋅ 10 = -90 - 60w : equivalent to -90 - 60w
C : -3(30 - 20w) = -90 + 60w : NOT equivalent to -90 - 60w
D : (6 + 4w)×15 = 90 + 60w : NOT equivalent to -90 - 60w
E : −20(4.5 + 3w) = - 90 - 60w : equivalent to -90 - 60w
SO THAT MEANS
A : -30(3+2w)
B : (-9-6w) ⋅ 10
E : −20(4.5 + 3w)

$420 is divided between A, B and C. B receives $20 less than A, and C receives half as much as A and B together. how much does each receive?
Also could you explain the answer?
Answer:
A = $150
B = $130
C = $140
Step-by-step explanation:
Let the amount received by a be $x
b receives $20 less than a;
we have that;
b = x - 20
c receives half of Sum A and B
c = (x + x-20)/2
c = (2x-20)/2
c = x - 10
Add all and it gives 420
x - 10 + x -20 + x = 420
3x -30 = 420
3x = 420 + 30
3x = 450
x = 450/3
x =$150
a = 150
b = x - 20; 150 - 20 = 130
c = x-10
c = 150-10
c = $140
