Solve: x0.09=0.81. Round to the hundredths place. Do not include "x=" in your answer.
The value of x in the equation x0.09 = 0.81 is 9
How to determine the value of x?The equation is given as
x0.09 = 0.81
Rewrite the above expression properly
So, we have:
x * 0.09 = 0.81
Divide both sides by 0.09
So, we have:
x = 0.81/0.09
Evaluate
x = 9
Hence, the value of x in the equation x0.09 = 0.81 is 9

What is a transformation ?
Transformations of co-ordinates can be calculated by taking reference from the original figure to the transformed figure by adding or subtrating the point values depending upon where they have transformed in X and Y co-ordinate.
In the given figure there are 4 points K,L,M,N and they have been transformed to K', L',M',N' each point having X and Y co-ordinate values.
K has moved 3 units right so 0

Find the value of x.
(4x12)°
(7x-28)
The value of x in the angles is 20
How to determine the value of x?The angles are given as
4x - 12 and 7x - 28
These angles are same side interior angles
So, we have
4x - 12 + 7x - 28 = 180
Collect the like terms
So, we have
4x + 7x - 12 - 28 = 180
Evaluate the like terms
So, we have
11x = 220
Divide both sides by 11
x= 20
Hence, the value of x in the angles is 20

Step-by-step explanation:
Is the power set of {2,3,4,5} a subset of the power set of {1,2,3,4,5,6}? Why or why not?
we get that the power set of {2, 3, 4, 5} a subset of the power set of {1, 2, 3, 4, 5, 6}.
We are given a power set:
A = {1, 2, 3, 4, 5, 6}
We are also given another power set:
B = {2, 3, 4, 5}
We need to tell if B is a subset of A or not.
We can see that every element of B is a part of A as well.
So, we can say that B is a subset of A.
B ⊂ A
{2, 3, 4, 5} ⊂ {1, 2, 3, 4, 5, 6}
Therefore, we get that the power set of {2, 3, 4, 5} a subset of the power set of {1, 2, 3, 4, 5, 6}.

Camilo uses 32 ounces of filling to make empanadas de queso. He puts 8 empanadas on each of 3 trays. Write a fraction to show how many ounces of filling Camilo uses in each empanada.
Answer: The fraction that will show the number of ounces of filling Camilo uses is x = 32 ounces
Step-by-step explanation:
Calculation by using fractions method :
The number of ounces used is x = 32
The number of trays = 3
Number of empanadas on each tray = 8
Therefore, the total number of empanadas on the 3 trays
= 3×8
= 24
If x = empanadas
32 ounce = x

((12-4)(3-2))^2 + square root of 64
Answer: 72
Step-by-step explanation: First step that I did was to subtract 12 and 4 to get 8. I then subtracted 3 and 2 to get 1. Then since 8 and 1 are in the parenthesis, I multiplied 8 and 1 to get 8. 8 to the 2nd power then comes out to 64. 64 adding the square root of 64 which is 8 then comes out to 64 plus 8 because the square root of 64 is 8. 64 plus 8 equals 72.
Find the value of "x" from the given figure...
[tex]....................[/tex]
Answer:
x = 21 cmStep-by-step explanation:
is a rhombus formed by 4 right triangles, let's consider the small / large couple
the triangle at the top and the triangle at the bottom are rectangles
we can solve with the Pythagorean theorem.
we find the side (cathetus) of the small onec² = 10² - 8²
c² = 100 - 64
c² = 36
c = √36
c = 6 cm
we find the side (cathetus) of the largestc² = 17² - 8²
c² = 289 - 64
c² = 225
c = √225
c = 15 cm
now we add the results and we have x6 + 15 =
21cm
Answer:
21 cm
Step-by-step explanation:
Let M be the point of intersection of the diagonals AD and BC.
[tex]\implies x=\sf AD=AM+MD[/tex]
As ΔAMD and ΔBMD are right triangles, use Pythagoras Theorem to work out the lengths of AM and MD.
Pythagoras Theorem
[tex]a^2+b^2=c^2[/tex]
where:
a and b are the legs of the right triangle.c is the hypotenuse (longest side) of the right triangle.[tex]\begin{aligned}\implies \sf BM^2+AM^2 & =\sf AB^2\\\sf 8^2+AM^2 & = \sf 10^2\\\sf 64+AM^2 & = \sf 100\\\sf AM^2 & = \sf 100-64\\\sf AM^2 & = \sf 36\\\sf AM & = \sf \sqrt{36}\\\sf AM & = \sf 6\:\: cm\end{aligned}[/tex]
[tex]\begin{aligned}\implies \sf BM^2+MD^2 & =\sf BD^2\\\sf 8^2+MD^2 & = \sf 17^2\\\sf 64+MD^2 & = \sf 289\\\sf MD^2 & = \sf 289-64\\\sf MD^2 & = \sf 225\\\sf MD& = \sf \sqrt{225}\\\sf MD& = \sf 15\:\: cm\end{aligned}[/tex]
Therefore:
