The number of classes per month that had same total amount paid was 21
The total amount is $115
How to find the total amountlet the number of group class be represented by x
first membership plan, Jen can pay $52 per month, plus $3 for each group class she attends
= $52 + $3x
second membership plan, Jen can pay $31 per month plus $4 per class
= $31 + $4x
when the total amount are equal
$52 + $3x = $31 + $4x
52 - 31 = 4x - 3x
21 = x
The total amount
= $52 + $3 * 21
= $115

Water is being from a pool. The volume of water in the pool t minutes after begin draining is given by the function V(t)=4522(0.94)^t. Which of the following is the closest to the percent volume that has drained out of the pool after 10 minutes
The closest percentage volume that has drained out is 46%
How to determine the percentage volume?From the question, we have the following parameters that can be used in our computation:
V(t) = 4522(0.94)^t
The initial volume is calculated when t = 0
So, we have
V(0) = 4522(0.94)^0
Evaluate
V(0) = 4522
The new volume is calculated when t = 10
So, we have
V(10) = 4522(0.94)^10
Evaluate
V(10) = 2435.62
The percentage is then calculated as
Percentage = (V(10) - V(0))/(V(0))
So, we have
Percentage = (2435.62 - 4522)/4522
Evaluate
Percentage = -46%
Hence, the percentage is 46%

What’s the value of z ?
Answer:
z = 7
Step-by-step explanation:
We know that, sum of the exterior angles of a quadrilateral is added up to 360°.
Accordingly,
115 + 7z + 12z + 16z = 360
Combine like terms.
115 + 35z = 360
Subtract 115 from both sides.
35z = 360 - 115
35z = 245
Divide both sides by 35.
z = 7

What is trigonometric ratios?Trigonometric functions are real functions in mathematics that connect an angle of a right-angled triangle to ratios of two side lengths. They are widely utilized in all geosciences, including navigation, solid mechanics, celestial mechanics, geodesy, and many more. The values of all trigonometric functions depending on the ratio of sides of a right-angled triangle are defined as trigonometric ratios. The trigonometric ratios of any acute angle are the ratios of the sides of a right-angled triangle with respect to that acute angle.
Here,
cos 30°=b/15
b=15*cos 30°
b=13 units
since this is square so all sides are equal.
sin 30°=p/15
p=15*sin 30°
p=7.5 units

y= x/2 -3 , y+3x = 12 and y = x are determined as linear equations , while y=6/x -2 and y= 3x^3 +5 are non-linear equations.
What do you mean by linear equations?A linear equation is a mathematical equation that forms a constant straight line on a graph.
What exactly is a nonlinear equation?Non-linear equations are functional equations that form different types of curves or other non-linear shapes on a graph.
According to the slope-intercept formula of the straight line : y=mx+b
1. y=6/x - 2 ,is not satisfying the above formula of straight line , having x in the denominator, hence it is a non-linear equation.
2. y=x/2-3 , here slope(m)=1/2 and intercept(b)=-3 which are real numbers and satisfy the straight line formula , hence it is a linear equation.
3. y=-3x+12, here slope(m)=-3 and intercept(b)=12 as real numbers and satisfy the straight line graph formula , hence it is a linear equation.
4. y = 3x^3+5, here slope(m)=3x^2 which is not a real number, hence not satisfying the given formula it is a non-linear equation.

Aeris reads the temperature of a liquid in a lab experiment. The temperature of the liquid is 7.2ºF. After 5 hours, she reads the temperature of the liquid again. The temperature of the liquid is now −1.6°F.
Aeris plots the points on a number line to determine the temperature change between these two readings.
How much did the temperature decrease?
Enter your answer as a decimal in the box.
[ ]
Answer: 8.8 (-8.8'F)
Step-by-step explanation:
What we know:
Temperature started as 7.2
Temperature ended as -1.6
We need to find the difference
How to solve:
By doing simple subtraction, we can solve this.
Process:
Write equation 7.2 - (-1.6) = ?
Simplify 7.2 + 1.6 = ?
Solve = 8.8
Solution: {8.8 (-8.8'F)}
The temperature decreased by 8.8'F, but it increased/changed by -8.8'F.
The product of four consecutive positive integers is 1 less than $461^2$. What is the least of these four numbers?.
Therefore, 20 is the lowest of the four numbers.
What is integers ?An integer, which can comprise both positive and negative integers, including zero, is a number without a decimal or fractional portion.
Integers include things like -5, 0, 1, 5, 8, 97, and 3,043. Z is a set of integers that consists of the following:
Positive, negative, and zero are all examples of integers.
The Latin word "integer" signifies "whole" or "intact." Thus, fractions and decimals are not included in integers.
According to our question-
4 numbers added together yields the product 4612 - 1.
The least of the four integers is the required information. Let N-2, N-1, N, and N + 1 be the numbers.
According to our calculations
, (N - 2)(N)(N + 1)(N - 1) = 4612 - 1 (N - 2)(N)(N + 1)(N - 1)- (4612 - 1) = 0
This results in N4 - 2N3 - N2 + 2N - 212520 = 0.:
(N + 21)(N - 22)(N2 - N + 460) = 0. N = 22 or -21 are hence potential solutions. However, the necessity for positive integers results in
N = 22 as a potential solution.
Because of this, where the four numbers are N-2, N-1, N, and N + 1, we get the following numbers:
22 -2, 22 -1, 22 + 1, which equals
20, 21, 22, and 23.
Therefore, 20 is the lowest of the four numbers.

A function is a relationship between inputs where each input is related to exactly one output.
The value of f(x) at x = 5 is -23.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
f(x) = -4 |x| - 3
The value of f(x) at x = 5.
f(5) = -4 |5| - 3
f(5) = -4 x 5 - 3
f(5) = -20 - 3
