Answer:
[tex]\boxed{\pink{\sf The \ number \ of \ cubes \ that \ can \ be \ fitted \ is 60 .}}[/tex]
Step-by-step explanation:
Given dimensions of the box = 20cm × 6cm × 4cm .
Dimension of the cube = 2cm × 2cm × 2cm .
Therefore the number of cubes that can be fitted into the box will be equal to the Volume of box divided by the Volume of the cube. So ,
[tex]\boxed{\red{\bf \implies No. \ of \ cubes \ = \dfrac{Volume \ of \ box}{Volume \ of \ cube }}}[/tex]
[tex]\bf \implies n_{cubes} = \dfrac{20cm \times 6cm \times 4cm .}{2cm \times 2cm \times 2cm } \\\\\bf\implies n_{cubes} = 10 \ times 3cm \times 2cm \\\\\implies \boxed{\bf n_{cubes}= 60 }[/tex]
Hence the number of cubes that can be fitted in the box is 60 .There are 3 consecutive odd integers that have a sum of 9.

On what interval(s) of x does f have negative concavity?
9514 1404 393
Answer:
positive concavity: nonenegative concavity: (-∞, ∞)Step-by-step explanation:
A parabola that opens downward has a second derivative that is negative everywhere. The interval of negative concavity is 'all real numbers', (-∞, ∞). There is no interval of positive concavity.

Complete the synthetic division to find the quotient of and .
Answer:
First Column: 8
Third Column: 24
Fourth Column: 4
Fifth Column (from top to bottom): 32; 0
This means that:
[tex](3x^3-25x^2+12x-32)\div (x-8)=3x^2-x+4[/tex]
Step-by-step explanation:
We can perform synthetic division when we divide a polynomial P(x) by a binomial in the form of (x - a).
When doing so, the number that goes to the very left of our structure will be the constant a.
We fill the first row with the coefficients of each term.
We are dividing [tex]3x^3-25x^2+12x-32[/tex] by [tex]x-8[/tex].
So, a = 8.
Therefore, for the first column, the number there is 8.
The second column has been filled out.
For the third column, we multiply the previous number by our a.
The previous number is 3. 3(8) is 24.
So, the number in the third column is 24.
(And we add 24 to -25 to acquire -1).
So, for the fourth column, we will add the two numbers to acquire (12 - 8) = 4.
Hence, the number for the fourth column is 4.
For the fifth column, the top box, it will again be the previous number multiplied by our a.
The previous number is 4. 4(8) is 32.
So, the number in the top box of the fifth column is 32.
And when added to -32, it equates to 0. Hence, the second box of the fifth column is 0.
This means that:
[tex](3x^3-25x^2+12x-32)\div (x-8)=3x^2-x+4[/tex]
Answer:
[tex] \frac{(3 {x}^{3} - 25 {x}^{2} + 12x - 32)}{(x - 8)} = (3 {x}^{2} - x + 4)\\[/tex]

A line passes through the point (-4 , -8) and has a slope of -3/2.
Write an equation in slope - intercept form for this line.
Answer:
[tex]y = \frac{-3}{2}x - 14[/tex]
Step-by-step explanation:
(-4 , -8) ; slope = (-3/2)
Equation of the line: y - y₁ = m( x- x₁)
[tex]y - [-8] = \frac{-3}{2}(x - [-4])\\\\y + 8 = \frac{-3}{2}(x +4)\\\\y + 8 = \frac{-3}{2}x +(\frac{-3}{2})*4\\\\y + 8 = \frac{-3}{2}x - 3 * 2\\\\ y = \frac{-3}{2}x -6 -8\\\\y = \frac{-3}{2}x - 14[/tex]

Lin has a scale model of a modern train. The model is created at a scale of 1 to 48. On the scale model, the distance between the wheels on the left and the wheels on the right is 1 1/4 inches. The state of Wyoming has old railroad tracks that are 4.5 feet apart. Can the modern train travel on these tracks?
No, modern train cannot travel on old railroad.
Step-by-step explanation:
In rail transport, track gauge is the spacing of the rails on a railway track and is measured between the inner faces of the load-bearing rails.
Most of the modern train are based on broad gauge. The separation in broad gauge is about 5 ft and 6 inches and in the standard gauge the separation between the tracks is 4 ft and inches. So for the modern train it is not possible to travel on the tracks whose separation is no more than 4.5 feet.

The amount of revenue in dollars, y, that Makayla receives from selling x posters is given by the equation y = 3x. The cost of producing x posters is given by the equation y = LaTeX: \frac{1}{3}x\:+\:2001 3 x + 200. How many posters does Makayla need to sell so that the cost and revenue are equal?
Group of answer choices
Answer:
75 posters
Step-by-step explanation:
Given
[tex]y = 3x[/tex] ---- Revenue
[tex]y = \frac{x}{3} + 200[/tex] --Cost of production
Required
Determine the number of posters that when cost equals revenue
To do this, we simply equate both equations
i.e. [tex]3x = \frac{x}{3} + 200[/tex]
Collect like terms.
[tex]3x - \frac{x}{3} = 200[/tex]
Multiply through by 3
[tex]3(3x - \frac{x}{3}) = 200*3[/tex]
[tex]9x - x = 600[/tex]
[tex]8x = 600[/tex]
Divide both sides by 8
[tex]\frac{8x}{8} = \frac{600}{8}[/tex]
[tex]x = \frac{600}{8}[/tex]
[tex]x = 75[/tex]
Radioactive Decay:
The half life of a
certain radioactive
substance is 46 days.
There are 12.6 g
present initally.
HELP PLS
The question is incomplete, here is the complete question:
The half-life of a certain radioactive substance is 46 days. There are 12.6 g present initially.
When will there be less than 1 g remaining?
Answer: The time required for a radioactive substance to remain less than 1 gram is 168.27 days.
Step-by-step explanation:
All radioactive decay processes follow first order reaction.
To calculate the rate constant by given half life of the reaction, we use the equation:
[tex]k=\frac{0.693}{t_{1/2}}[/tex]
where,
[tex]t_{1/2}[/tex] = half life period of the reaction = 46 days
k = rate constant = ?
Putting values in above equation, we get:
[tex]k=\frac{0.693}{46days}\\\\k=0.01506days^{-1}[/tex]
The formula used to calculate the time period for a first order reaction follows:
[tex]t=\frac{2.303}{k}\log \frac{a}{(a-x)}[/tex]
where,
k = rate constant = [tex]0.01506days^{-1}[/tex]
t = time period = ? days
a = initial concentration of the reactant = 12.6 g
a - x = concentration of reactant left after time 't' = 1 g
Putting values in above equation, we get:
[tex]t=\frac{2.303}{0.01506days^{-1}}\log \frac{12.6g}{1g}\\\\t=168.27days[/tex]
Hence, the time required for a radioactive substance to remain less than 1 gram is 168.27 days.
write the two tenths closest to 0.446 in the place-value chart.
Answer:
1,2
Step-by-step explanation:
The place-value chart's two tenths closest to 0.446 is 0.4. We can determine the place value of each digit based on its location in a number using the place value chart, which is a very useful table structure.
What is meant by place value chart?The place value chart is a very helpful table structure that enables us to determine each digit's place value based on where it is in a number. On the place value chart, a digit's place value increases as we move left and drops as we move right by a factor of ten.
Using a place value chart, we may compare the place values of the digits in a number and determine a digit's exact position. In this graph or figure, the place value of a number's digits increases as we move to the left and drops as we move to the right.
Given
0.446
In ones place is 0
In tens place is 4
In hundredth place is 4
In thousand place is 6
Therefore, The place-value chart's two tenths closest to 0.446 is 0.4.

All the words in the Snowman language consist of exactly seven letters formed from the letters {s, no, wm, an} arranged in some order where the paired letters cannot be separated. For example "snonono" and "sssanwm" are words in the language but "sssmwan" and "sssawmn" are not. How many words are there in the Snowman language?
Answer:
24
Step-by-step explanation:
Imagine s is 1, no is 2, wm is 3, and an is 4.
If you look at all the possible ways to orginaze the numbers starting with one you get 6;
1234
1243
1324
1342
1432
1423
you then need to multiply this by the amount of numbers that could be in the start; which is four; 1, 2, 3, and 4. So, six ways to orginaze multiplied by 4 numbers is 24.
In Snowman language, total words are 24.
What is permutation and combination?Permutation and combination are ways to arrange values in a set. In permutation the order of arrangement matters, but in combination the order of arrangement does not matter,
Given that,
Total number of letters in Snowman language = 7
The letters are in form of {s, no, wm, an}.
To find the total words in Snowman language,
Consider the following: s = 1, no = 2, wm = 3, and an = 4.
If you consider every possible method to order the numbers beginning with one, you will arrive at the number 6;
1234
1243
1324
1342
1432
1423
You must then multiply this by the total number of possible numbers at the beginning, which is four: 1, 2, 3, and 4. Six possible organizations divided by four digits equals 24.
So, the total words in Snowman language is 24.
