Answer: 43.2 minutes or 43 minutes and 12 seconds
Hi there, so first step I would do is to state the area of a cylinder which is 2πrh+2πr^2
Next step, I would place the value into the equation, so for the first pool, it is as follows: 2 x π x 20 x 5+2 x π x 20^2 which is = 1000π
which means 1000π = 50 minutes so each minutes must be equals to 20π
Then fit in the values for the second pool
2 x π x 18 x 6 + 2 x π x 18^2 = 864π
Then divide 864π by 20π to get how many minutes
The answer is equal to 43.2 minutes
Hope this helps

A negative relationship exists when two connected variables move in opposite directions. As a result, Option A is right which has a downward slope and variables that are negatively correlated.
An inverse correlation, sometimes referred to as negative correlation, is a relationship between two variables in which, when one variable's value is high, the other variable's value is likely low.
For instance, with the variables A and B, when A is high, B is low, and when A is low, B is high. In statistical nomenclature, an inverse correlation is frequently expressed by the correlation coefficient "r," which has a value between -1 and 0, with r = -1 signifying complete inverse correlation.

The measure of angle x is 70°
Triangle Exterior Angle Theorem:
For a triangle, the exterior angle is the angle formed by extending one of the sides of the triangle
The Triangle Exterior Angle Theorem states that the measure of an exterior angle of a triangle is equal to the sum of the measures of the two non-adjacent interior angles.
Here we have
A triangle where 105° is an exterior angle
And 'x' is an interior angle
Name the given triangle as given below
If we take AC as Transversal which cuts AB and DC
=> ∠A = 35° [ Alternate Interior Angles ]
In a triangle,
The measure of an exterior angle will equal to the sum of measures of opposite interior angles.
=> x° + 35° = 105°
=> x° = 105° - 35°
=> x° = 70°
Therefore,

Given that angles A and B both lie between 0 and 360, and that sin A and cos B are both negative, find the values between which A + B must lie.
Answer:
A + B must lie between 90 and 450 degrees.
Explanation:
Since sin A and cos B are both negative, A and B must lie in the third quadrant or the fourth quadrant. In the third quadrant, sin A and cos B are both negative, while in the fourth quadrant, sin A is negative and cos B is positive.
Let's consider the case where A and B are both in the third quadrant. In this case, both A and B are between 180 and 270 degrees. Since A + B is the sum of two angles in this range, it follows that A + B must be between 360 and 450 degrees.
Now let's consider the case where A is in the fourth quadrant and B is in the third quadrant. In this case, A is between 270 and 360 degrees, while B is between 180 and 270 degrees. Since sin A is negative and cos B is positive, it follows that cos A and sin B are both negative. Using the identities sin(180 - x) = sin x and cos(180 - x) = -cos x, we can write:
sin A + cos B = sin(180 - (180 - A) - B) + cos(180 - (180 - A) - B)
= sin(180 - A) - cos(180 - B)
= -sin A - cos B
Therefore, A + B is the difference of two angles in the third quadrant, and it must be between 90 and 180 degrees.
Putting the two cases together, we see that A + B must lie between 90 and 450 degrees.

Answer and Step-by-step explanation:
To write the quadratic equation, we need to find the values of a, b, and c in the general form of a quadratic equation:
y = ax^2 + bx + c
Using the given data, we can plug in the x- and y-values to get a system of equations:
-12 = 16a - 4b + c
-5 = 9a - 3b + c
0 = 4a - 2b + c
We can solve this system of equations using substitution or elimination to get:
a = -1
b = 3
c = 4
Substituting these values into the general form of the quadratic equation, we get:
y = -x^2 + 3x + 4
Therefore, the quadratic equation from the table is:
y = -x^2 + 3x + 4

Describe Algebraic Expression?In mathematics, an algebraic expression is a combination of variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division. Algebraic expressions are used to represent and solve problems in various areas, including science, engineering, economics, and mathematics.
An algebraic expression can contain one or more variables, which represent unknown or changing quantities, and one or more constants, which represent fixed values. The variables are usually represented by letters, such as x, y, or z. The operations of addition, subtraction, multiplication, and division are represented by the symbols +, -, ×, and ÷, respectively. Parentheses are also used to group terms and indicate the order of operations.
For example, the algebraic expression 3x + 2y - 5 represents a combination of two variables, x and y, and three constants, 3, 2, and 5. The terms 3x and 2y are the variables multiplied by their coefficients, while -5 is a constant term.
Algebraic expressions can be simplified by combining like terms, which are terms that have the same variable raised to the same power. For example, in the expression 3x + 2y - 5 + 4x - 3y, the like terms are 3x and 4x, and 2y and -3y. Combining these terms yields the simplified expression 7x - y - 5.
Algebraic expressions are used in various mathematical operations, such as solving equations, graphing functions, and evaluating formulas. They are also used in real-world applications, such as calculating interest rates, solving optimization problems, and modeling physical phenomena.
Sure, here's a word problem that fits the inequality 6x - 4 < 46:

You're given the rational number 46/224. You can choose to add 10 to the numerator or add 10 to the denominator. Which option will give you a larger final number?
Answer:
Therefore, adding 10 to the numerator is the better option if we want to increase the value of 46/224.
Step-by-step explanation:
To find which option will give a larger final number, we should calculate both the possibilities and compare them ,
Firstly,add 10 to the numerator
Now,
The new rational number will be,
(46 + 10) / 224
= 56 / 224
= 7 / 28
2ndly,
Add 10 to the denominator
The new rational number will be,
46 / (224 + 10)
= 46 / 234
After comparing these two rational numbers and converting them to decimals or simplify them ,
7 / 28
= 0.25
46 / 234
= 0.196581...
Since 0.25 is larger than 0.196581...,
Now,adding 10 to the numerator will result in a larger final number.
Therefore, adding 10 to the numerator is the better option if we want to increase the value of 46/224.

To find the 95% confidence interval for the difference in proportions of patients experiencing stress relief from the yoga and meditation groups, we need to use the formula:
CI = (p1 - p2) ± z*√[(p1(1-p1)/n1) + (p2(1-p2)/n2)]
Where p1 and p2 are the proportions of patients experiencing stress relief in the yoga and meditation groups, respectively, n1 and n2 are the sample sizes of the yoga and meditation groups, respectively, and z is the critical value from the z-table corresponding to the 95% confidence level.
Plugging in the given values:
p1 = 30/50 = 0.60
p2 = 35/50 = 0.70
n1 = 50
n2 = 50
z = 1.96 (from the z-table for a 95% confidence level)
CI = (0.60 - 0.70) ± 1.96*√[(0.60(1-0.60)/50) + (0.70(1-0.70)/50)]
CI = (-0.10) ± 1.96*√[(0.24/50) + (0.21/50)]
CI = (-0.10) ± 1.96*√[0.009]
CI = (-0.10) ± 1.96*(0.095)
CI = (-0.10) ± 0.186
Therefore, the 95% confidence interval for the difference in proportions of patients experiencing stress relief from the yoga and meditation groups is (-0.286, 0.086).
