Step-by-step explanation:
To simplify the expression x^-2y(x^3y^5)^3, we need to perform the operations inside the parentheses first, using the exponent rule that (a^m)^n = a^(mn):
x^-2y(x^3y^5)^3 = x^-2y(x^(33)y^(53)) = x^-2y(x^9y^15)
Next, we can simplify the expression by multiplying the coefficients (numbers) and adding the exponents of x and y, using the product rule that x^mx^n = x^(m+n) and (xy)^m = x^my^m:
x^-2y(x^9y^15) = (1y/x^2)(x^9*y^15) = y^(15+1)x^(9-2) = y^16x^7
Therefore, the simplified form of x^-2y(x^3y^5)^3 is y^16*x^7.
Note that this expression is defined for all values of x and y except for x=0.
if 85% of 'a' is 'b' then which of the following is true a, a=b b,ab
Answer:
Step-by-step explanation:
The statement "85% of 'a' is 'b'" can be represented mathematically as:
0.85a = b
This means that 'b' is 85% of 'a'.
To answer the question:
a = b/0.85
So, a is equal to 'b' divided by 0.85.
Therefore, the correct option is (a) a=b.

Answer:
54 square meters
Step-by-step explanation:
Given the scale is 1 centimeter represents 3 meters, to scale the dimensions of the drawing to the dimensions of the actual room, multiply the dimensions of the drawing by 3.
Therefore:
3 cm × 3 = 9 m2 cm × 3 = 6 mSo the dimensions of the actual room are:
Length = 9 mWidth = 6 mThe area of a rectangle is the product of its width and length.
Therefore, the area of the actual room is:
Area = 6 × 9 = 54 m²Solve 58 - 10x ≤ 20 + 9x.
Tara uses 6.6 pints of white paint and blue paint to paint her bedroom walls. 3 4 of this amount is white paint, and the rest is blue paint. How many pints of blue paint did she use to paint her bedroom walls?
Answer:
1.65 pints
Step-by-step explanation:
If Tara used 6.6 pints of white and blue paint combined, and 3/4 of that amount is white paint, then we can find the amount of white paint she used by multiplying 6.6 by 3/4:
6.6 x 3/4 = 4.95
So Tara used 4.95 pints of white paint to paint her bedroom walls.
To find out how much blue paint she used, we can subtract the amount of white paint from the total amount of paint:
6.6 - 4.95 = 1.65
Therefore, Tara used 1.65 pints of blue paint to paint her bedroom walls.

What is the principal square root? And why is it used when solving radical
polynomials?
Answer:
The principal square root of a non-negative real number is the positive square root. For example, the principal square root of 25 is 5, since 5^2 = 25.
When solving radical polynomials, the principal square root is used because it is the most commonly used square root. In many contexts, including mathematical and scientific calculations, the principal square root is the default choice unless otherwise specified. Additionally, when working with radical expressions, we often simplify expressions by taking the principal square root, as it can help us to simplify calculations and express answers more clearly.

What is a solid figure?A solid figure is a three-dimensional geometric shape that has length, width, and height. It is also called a three-dimensional or 3D figure. Some examples of solid figures include cubes, spheres, cylinders, cones, and pyramids.
Solid figures are different from two-dimensional shapes, which only have length and width. In contrast, solid figures have depth or thickness, making them more complex and interesting.
Solid figures can be classified based on their properties, such as the number of faces, vertices, and edges they have. For example, a cube has six faces, eight vertices, and 12 edges, while a sphere has no faces, vertices, or edges.
In this case, it has 2 squares and 4 rectangles. The appropriate diagram is D

What is the x and the y Intercept?
For the given function the intercepts are:
x-intercept: x = -4
y-intercept: y = 12.
How to find the intercepts for the given function?Here we have a table that defines a function, and we want to find the intercepts of said function.
We can assume it is linear, then the slope of the function will be given by:
a = (9 - 3)/(-1 + 3) = 6/2 = 3
The linear function is like:
y = 3x + b
To find the value of b we can replace the values of the last point on the table, x = 2 and y = 18.
18 = 3*2 + b
18 = 6 + b
18 - 6 = b = 12
The linear function is:
y = 3x + 12
The x-intercept is the value of x when y = 0
0 = 3*x + 12
-12 = 3x
-12/3 = x = -4
And the y-intercept is the value of y when x = 0.

a) The percentage of adults in the USA that have stage 2 high blood pressure is; 0.27%
b) The number of people that you will expect to have BP greater than 160 is; 54
How to get p-value from z-score?a) if x is systolic blood pressure, then want to find probability that x ≥ 160.
The formula for z-score is;
z = (x - mean)/standard deviation
Thus;
z = (x - 119)/18
This is normally distributed with mean 0 and standard deviation 1
Transform x to z:
P(x > 160) = P(z > (160 - 119)/18)
= P(z > 2.78)
= P(z < -2.78)
= 0.0027 (from standard normal distribution table, which 0.27%.)
b) Since probability of BP > 160 is 0.027.
Then out of 2000 people, then 2000 * 0.027 = 54 people would have BP > 160.
