Shelby is walking through her favorite store and sees a shirt she likes being sold for $80.00. She then notices the store is having a 45% off sale on all items. Excited to purchase the shirt, she grabs it and goes to the cash register. As she’s taking out her wallet, she finds a coupon for 25% off (that is applied after the store’s sale). What is the final price of the shirt that Shelby pays after the two discounts?
a. $9.00
b. $33.00
c. $28.00
d. $52.00
first we go 45+25=70 so now 80-70=$10.00
Did you mess up one of the answer because I did it two ways and got 10.00?

Two swimming pools are being drained so that they can be repaired. The two equations below describe the depth of the two pools, d, as a function of time in hours, t.
d=5 - 1/4t. d=7 - 1/3t
Ted wants to know when the two pools will reach the same depth. He solves the system by equating the two equations for d and then solving for t. The solution he finds is t = 24, so he concludes that after 24 hours the pools will be the same depth. Is Ted’s conclusion reasonable? Why or why not?
A. Yes, Ted’s conclusion is reasonable. Setting the two equations equal and solving for t will solve for the time when the two pools are at the same depth.
B. Yes, Ted’s conclusion is reasonable. Substituting into both equations yields the same value for d, which is the depth of the pools.
C. No, Ted’s conclusion is not reasonable. Ted failed to take into account the limits on the domain and range of the two functions.
D. No, Ted’s conclusion is not reasonable. Ted made a math error when he was finding a common denominator when solving for t.
Yes, Ted’s conclusion is reasonable.
Setting the two equations equal and solving for t will solve for the time when the two pools are at the same depth.
Option A is the correct answer.
What is an equation?An equation is a mathematical statement made up of two expressions connected by an equal sign.
We have,
d = 5 - (1/4)t ____(1)
d = 7 - (1/3)t ____(2)
Now,
The time at which the depth d is the same.
Make (1) and (2) equal.
5 - (1/4)t = 7 - (1/3)t
(1/3)t - (1/4)t = 7 - 5
(4t - 3t)/12 = 2
t = 2 x 12
t = 24
Thus,
Yes, Ted’s conclusion is reasonable.

What is log function?
The logarithm (log) function is a mathematical function used to determine the logarithm of a number. The logarithm of a number is the exponent to which a particular base must be raised in order to produce that number. For example, the logarithm of 8 with base 2 is equal to 3 because 2 to the third power is 8. In mathematics, the logarithm of a number can be expressed as logbX, where b is the base and X is the number.
Step-by-step explanation:
We can write -
0.006 = 6 x 10^-3
10ⁿ = 6 x 10^-3
[tex]10^{n+3}[/tex] = 6
log([tex]10^{n+3}[/tex]) = log(6)
(n + 3) log 10 = log (6)
n +3 = log(6)/log(10)
n + 3 = 0.78
n = -3 + 0.78
n = -3 (approx.)

TR
The amount of each payment is $699.
What is payment?
Payment refers to the exchange of something of value as a condition of a contract. While one party pays money and receives something else of value, the other party gets paid in return for delivering a good or service. Physical currency was once the most common form of payment, but nowadays most forms of payment use technology.
Given: Buy 2 personal watercrafts for $3,495 each.
So, the price for 2 watercrafts is, 2 x $3495 = $6990
They make 10 equal payments for the watercrafts.
So each payment is of $6990/10 = $699.
Hence, the amount of each payment is $699.

A tank has an intake valve and a release valve. The rate of follow through each valve is inversely proportional to the area of its cross-section. The cross-section area of the input can be described by the equation, f(x)= x^2+2x+1; The cross-section area of the release can be described by the equation, f(x)= x^2+4x+3. If the proportion constant is equal for the input and output, find x such that the volume of material in the tank remains constant.
Answer:
x = - 1------------------------------
The volume will remain constant if both input and output cross - sections are equal:

How do i prove that .......... if F, G, and H are scalar fields?
The cross product or the curl of F, G, and H are zero so they are scaler fields.
What are dot products and cross products?The cosine of the angle between the vectors and their magnitude are combined to form the dot product.
The dot product is represented by A.B = ABCos θ.
The sine of the angle between the vectors and their magnitude are combined to form the cross-product.
The cross product is represented by A×B = ABSin θ.
Given, F × (G × H) = (F . H)G - H(F .G).
∴ F × (G × H) = (FHcosФG) - H(FGcosФ).
F × (G × H) = FGHcosФ - FGHcosФ.

Question 1:
Joe and Sara are each running a 5k. In the age/ability group that Joe is running in, the average run time is 22:30 minutes/seconds with a standard deviation of 4 minutes. In the age/ability group that Sara is running in, the average run time is 31:15 minutes/seconds with a standard deviation of 6 minutes.
Joe's run time is 19:45. Sara's run time is 28:20. Compute the z-scores for each and thus make a claim about who ran a better race compared to their age/ability group.
Question 2:
Suppose a data set has a mean 50 and standard deviation 5. If the Z-score of a data value is -2, what is the actual score?
1. The z-scores are given as follows:
Joe: Z = -0.6875.Sara: Z = -0.49.Due to the lower z-score, Joe had a better time.
2. The actual score is of 40.
What are z-scores?The z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.Considering the mean and the standard deviation for his distribution, and also that 15 seconds = 0.25 minutes, the z-score for Joe is obtained as follows:
Z = (19.75 - 22.5)/4
Z = -0.6875.
For Sara, the z-score is calculated as follows:
Z = (28.33 - 31.25)/6
Z = -0.49.
Joe had a better time, as his lower z-score means that a lower percentage of runners spent less time than him, that is, a lower percentage of runners ran faster than him.
For item 2, the actual score is calculated as follows:
-2 = (X - 50)/5
X - 50 = -10
X = 40.

What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
We know that the product of slopes of perpendicular lines is -1.

A TPN solution contains 8.25 % amino acids it. If the patient needs 75 grams of protein per day, how much of the TPN solution should the patient receive per day?
The patient should receive 909 mL of the TPN solution per day.
To determine the amount of the TPN solution the patient should receive per day, we need to use the following formula:
amount of TPN solution = (grams of protein needed / percentage of amino acids in TPN solution) × 100
In this case, we are given that the TPN solution contains 8.25% amino acids and that the patient needs 75 grams of protein per day. Substituting these values into the formula, we get:
amount of TPN solution = (75 / 8.25) × 100
amount of TPN solution = 9.09 × 100
amount of TPN solution = 909 mL
Therefore, the patient should receive 909 mL of the TPN solution per day.

Answer:
A, C
Step-by-step explanation:
You want to know which answer choices are angles that are coterminal with 3π/2.
CoterminalAngles are coterminal when their terminal rays lie in the same position. In general, any angle will be coterminal with angles that are an integer multiple of 2π added to the original.
That is, an angle is coterminal with all angles that have the same value modulo 2π.
For the given angle and each of the answer choices, the attachment calculates the coefficient of π modulo 2. The ones that match the given angle are ...
A. 11π/2 mod 2π = 3π/2
C. -7π/-2 mod 2π = 3π/2
__
Additional comment
Both -π/-2 and π/2 match the angle π/2, which is not the same as 3π/2.
Of course, the minus signs in numerator and denominator cancel, so -7π/-2 is the same as 7π/2.
