The answer is 0.2.
Here,
We have to find the number as 'the answer to 0.02 is 1/10 of the number.'
What is Mathematical expression?
The combination of numbers and variables by using operations addition, subtraction, multiplication and division is called Mathematical expression.
Now,
Let the number is x.
Then, By given condition the expression is written as;
0.02 = (1/10) * x
(1/10) * x = 0.02

A 96 in. board will be cut into pieces to add a decorative trim to a rectangular table. The length of the table is twice the width. All of the board will be used to add the trim, and the board will be cut into only four pieces to match the four sides of the table. Find the location of the cut marks on the board...
Answer:
16, 16, 32, 32
Step-by-step explanation: If you take 92 and divide it by 4 you get 24 but you need one side to be longer than the other, subtract 6 and you get 16, and 16x2 is 32, if you add 16+16+32+32 you get 96.

Hello...
Step-by-step explanation:
AB = 6x + 2 and
BC = 5x + 3
Find AC.
That is a difficult one
Assuming A, B and C are all on the same straight line, this means,
AB+BC = AC
through the segment addition postulate.
So,
AC = AB+BC
AC = (6x+2)+(5x+3)
AC = 6x+2+5x+3
AC = (6x+5x)+(2+3)
AC = 11x+5- 5 .5 ( d - 2 ) = - 12. 1
Answer:
D = 4.2
Step-by-step explanation:
-5.5 ( d - 2 ) = - 12.1
-5.5d + 11 = - 12.1
11 + 12.1 = 5.5d
23.1 = 5.5d
d = 23.1 ÷ 5.5
d = 4.2

According to the first scale, 2 red balls = 1 star.
According to the second scale, 2 triangles = 1 star
So,
1 triangle = 1 red ball
1 star = 2 red balls
1 red ball = 1 red ball
Therefore, 2 + 1 + 1 = 4 red balls
The last scale needs 4 red balls

What is the product of 2x - 5 and 3x2 + 5x - 7? Write your answer in standard form.
Answer:
(2x - 5) (3x^2 + 5x - 7) = 6x^3 - 5x^2 - 39x + 35
Step-by-step explanation:
Given:
2x - 5 and 3x2 + 5x - 7
Product of two values means multiplication of the two values
(2x - 5) (3x^2 + 5x - 7)
6x^3 + 10x^2 - 14x - 15x^2 - 25x + 35
Collect like terms
6x^3 + 10x^2 - 15x^2 - 14x - 25x + 35
Simplify
6x^3 - 5x^2 - 39x + 35
(2x - 5) (3x^2 + 5x - 7) = 6x^3 - 5x^2 - 39x + 35
Therefore product of 2x - 5 and 3x2 + 5x - 7 is 6x^3 - 5x^2 - 39x + 35

Answer:
1) [tex]\frac{dy}{dx}=12x^2+6x-6[/tex]
2) [tex]x\leq-1\text{ or } x\geq 1/2[/tex]
Step-by-step explanation:
So we have the equation:
[tex]y=4x^3+3x^2-6x-1[/tex]
Part A)
We want to find the derivative of the above function. So:
[tex]\frac{dy}{dx}=\frac{d}{dx}[4x^3+3x^2-6x-1][/tex]
Expand:
[tex]\frac{dy}{dx}=\frac{d}{dx}[4x^3]+\frac{d}{dx}[3x^2]+\frac{d}{dx}[-6x]+\frac{d}{dx}[-1][/tex]
Use the power rule. Therefore, our derivative is:
[tex]\frac{dy}{dx}=3(4x^2)+2(3x)+(-6)+(0)[/tex]
Simplify:
[tex]\frac{dy}{dx}=12x^2+6x-6[/tex]
Part B)
We want to find the range of the values of x such that:
[tex]\frac{dy}{dx}\geq 0[/tex]
So, all we have to do is substitute our derivative in:
[tex]12x^2+6x-6\geq0[/tex]
And solve for this quadratic inequality!
Solve it normally. Pretend the inequality is with an equal sign. So:
[tex]12x^2+6x-6=0[/tex]
Divide everything by 6:
[tex]2x^2+x-1=0[/tex]
Factor. We can use -2 and 1. So:
[tex]2x^2+2x-x-1=0[/tex]
From the first two terms, factor out 2x.
From the third and fourth terms, factor out a negative. So:
[tex]2x(x+1)-(x+1)=0[/tex]
Grouping:
[tex](2x-1)(x+1)=0[/tex]
Zero Product Property:
[tex]2x-1=0\text{ or } x+1=0[/tex]
Solve for x in each case:
[tex]x=1/2\text{ or } x=-1[/tex]
So, the zeros of our function is -1 and 1/2.
Looking above, we can see that this is a greater than inequality.
Since this is a greater than inequality, our solution is all values to the left of the first zero and all values to the right of the second zero.
Therefore, our solution is:
[tex]x\leq-1\text{ or } x\geq 1/2[/tex]
In interval notation, this is:
[tex](-\infty,-1]\cup[1/2,\infty)[/tex]
So, for all values within the above interval, our derivative, dy/dx, will be greater than or equal to 0.
And we're done!
