The pool manager pays $54 for the chlorine tablets and $6.60 for the pH test kit.
Explanation:The pool manager pays $54 for the bucket of chlorine tablets and $6.60 for the pH test kit after applying the 40% discount.
To find the price of the chlorine tablets after the discount, we multiply $90 by 40% to get $36. Subtracting $36 from $90 gives us the final price of $54.To find the price of the pH test kit after the discount, we multiply $11 by 40% to get $4.40. Subtracting $4.40 from $11 gives us the final price of $6.60.Therefore, the pool manager pays $54 for the chlorine tablets and $6.60 for the pH test kit.

The pool manager pays the cost of $54 for the chlorine tablets and $6.60 for the pH test kit.
Explanation:The calculation you're looking to perform is a simple example of a percentage discount on a sum of money. To figure out how much the pool manager pays for each item, you have to first calculate the total cost of the items. The total cost of both the bucket of chlorine tablets ($90) and the pH test kit ($11) is $101.
A 40% discount on the total cost is then calculated by taking 40% of $101, which is $40.40. This discount is subtracted from the total cost (101-40.40), leaving the pool manager to pay $60.60. To determine the cost of each item after the discount, we assume that the discount was applied equally to both items.
This means that the cost price for each the bucket of chlorine tablets and pH test kit, after the discount, would be $54 and $6.60 respectively.

How many sides does a polygon have if the sum of its interior angles is 9000 degrees?
Answer:
52 sides
Step-by-step explanation:
The only way I know how to do this is to create one fraction which is a combination of 2 steps used when 1 of the interior angles is known.
Formula
360/(180 - 9000/s ) = s
Multiply denominator and numerator on the left by s.
360 * s
======= = s
s* (180 - 9000/s)
Remove the brackets on the denominator
360s
================ =s
180s - 9000
Cancel the numerators s's.
360 / (180s - 9000) = 1
Multiply both sides by 180s - 9000
360 =180s - 9000
Add 9000 to both sides
360 + 9000 = 180s
9360 = 180s
Divide by 180
9360/180 = 180/180 s
s = 52

In a right triangle, side a is 3 times as long as side b, and side c is 30 cm. Using the Pythagorean Theorem, what are the lengths of sides a and b? Round your answers to the nearest tenth.
Answer:
a = 9√10
b=3√10
Step-by-step explanation:
see attached for reference for any right triangle
in our case
c is the hypotenuse
hence
c² = a² + b²
we are given that c = 30
also that a is 3 times as long as b or,
a = 3b
substituting these into the pytharogrean formula.
c² = a² + b²
30² = (3b)² + b²
900 = 9b²+b²
10b² = 900
b² = 90
b = √90 = √9 √10 = 3√10
earlier we found that a = 3b,
hence
a = 3(3√10)
a = 9√10
U and V are mutually exclusive events. P(U) = 0.27; P(V) = 0.56. Find:
P(U and V) =
b. P(U|V) =
c. P(U or V) =
Answer:
(a) P (U and V) = 0.
(b) P (U|V) = 0.
(c) P (U or V) = 0.83.
Step-by-step explanation:
Mutually exclusive events are those events that cannot occur at the same time. That is, if events A and B are mutually exclusive then,
[tex]P (A\cap B) = 0[/tex]
Given:
Events U and V are mutually exclusive.
P (U) = 0.27 and P (V) = 0.56
(a)
As events U and V are mutually exclusive, the probability of their intersection will be 0.
That is,
[tex]P(U\ and\ V) = P (U\cap V) = 0[/tex]
Thus, the value of P (U and V) is 0.
(b)
The conditional probability of event B given A is:
[tex]P(B|A) =\frac{P(A\cap B)}{P(B)}[/tex]
Compute the value of P (U|V) as follows:
[tex]P(U|V) =\frac{P(U\cap V)}{P(V)}\\=\frac{0}{0.56}\\ =0[/tex]
Thus, the value of P (U|V) is 0.
(c)
The probability of the union of two events, say A and B, is
[tex]P(A\ or\ B)=P(A\cup B)=P(A)+P(B)-P(A\cap B)[/tex]
Compute the value of P (U or V) as follows:
[tex]P(U\ or\ V)=P(U\cup V)\\=P(U)+P(V)-P(U\cap V)\\=0.27+0.56-0\\=0.83[/tex]
Thus, the value of P (U or V) is 0.83.
The events U and V are mutually exclusive. So, the value of P(U and V) is 0, the value of P(U|V) is 0, and the value of P(U or V) is 0.83 and this can be determined by using the given data.
Given :
P(U) = 0.27P(V) = 0.56U and V are mutually exclusive events.A) P(U and V)
P(U and V) = P(U [tex]\cap[/tex] V) = 0
Because U and V are mutually exclusive events.
B) P(U|V)
[tex]\rm P(U|V) = \dfrac{P(U\cap V)}{P(V)}[/tex]
[tex]\rm P(U|V) = \dfrac{0}{0.56}[/tex]
P(U|V) = 0
C) P(U or V)
[tex]\rm P(U \;or\;V) = P(U\cup V)[/tex]
[tex]\rm P(U \;or\;V) = P(U)+P(V)-P(U\cap V)[/tex]
P(U or V) = 0.27 + 0.56 - 0
P(U or V) = 0.83
The events U and V are mutually exclusive. So, the value of P(U and V) is 0, the value of P(U|V) is 0, and the value of P(U or V) is 0.83 and this can be determined by using the given data.

a rectangular prism has a volume of 10 cubic units. If the length width and height of the prism are all each made 3 times as long what is the new volume?
Answer:
270 units³
Step-by-step explanation:
l×w×h = 10
lwh = 10
New Volume = (3l)×(3w)×(3h)
= 27×lwh
= 27×10
= 270 units³
Alternately,
Since the sides are increased in the same ratio,
The two prisms are similar figures
For similar figures,
volume1/volume2 = (side1/side2)³
New Volume/10 = (3/1)³ = 27
New Volume = 270 units³
Final answer:
The new volume of a rectangular prism, whose dimensions are tripled, is calculated by cubing the factor of increase (3) and multiplying it by the original volume. The new volume will be 270 cubic units.
Explanation:
If the original volume of a rectangular prism is 10 cubic units and the length, width, and height are all made three times as long, the new volume can be calculated using the principle that volume is proportional to the cube of the linear dimensions of the prism. This is often represented as V imes L³ where V is volume and L is the linear dimension.
To find the new volume, you would multiply each dimension by 3 so the new length (L'), width (W'), and height (H') would be three times the original dimensions. The new volume would then be calculated as:
V' = L' times W' times H' = (3L) times (3W) times (3H)
Since the original volume (V = L imes W imes H) is given as 10 cubic units, and you've multiplied each dimension by 3, you would cube the factor of increase (3³ = 27) and multiply it by the original volume:
V' = 27 imes V = 27 imes 10 = 270 cubic units
Therefore, the new volume of the rectangular prism would be 270 cubic units.

How do you convert fraction to percent
Answer: dividing
Step-by-step explanation:
Final answer:
To convert a fraction to a percent, divide the numerator by the denominator to get a decimal, multiply the decimal by 100, and then add the percent symbol (%).
Explanation:
To convert a fraction to a percent, you start by converting the fraction into a decimal. To do this, divide the numerator (the top number) by the denominator (the bottom number). Once you have the decimal, you multiply it by 100 to get the percent value. Finally, append the percent symbol (%) to the number.
Example:
For the fraction 3/4, first convert it to decimal:
Divide 3 by 4 to get 0.75.Multiply 0.75 by 100, which equals 75.So, 3/4 as a percent is 75%.Another way to convert fractions to percent is by finding an equivalent fraction that has 100 as its denominator. Then, simply use the numerator as the percent. If the fraction's denominator is not easily scalable to 100, it is easier to use the decimal method described previously.

Thank you so much please help asap!!
Answer:
The length of rectangle is 14.25 inches and the width of rectangle is 8.25 inches
Step-by-step explanation:
we know that
The perimeter of rectangle is equal to
[tex]P=2(L+W)[/tex]
[tex]P=45\ in[/tex]
so
[tex]45=2(L+W)[/tex]
simplify
[tex]22.5=L+W[/tex] -----> equation A
The length of a rectangle is 6 inches more than its width
so
[tex]L=W+6[/tex] ----> equation B
Solve the system by substitution
substitute equation B in equation a
[tex]22.5=(W+6)+W[/tex]
solve for W
[tex]22.5=2W+6\\2W=22.5-6\\2W=16.5\\W=8.25\ in[/tex]
Find the value of L
[tex]L=W+6[/tex]
substitute the value of W
[tex]L=8.25+6=14.25\ in[/tex]
therefore
The length of rectangle is 14.25 inches and the width of rectangle is 8.25 inches
If the volume of the prism is 294 cubic inches, what is the area of the base

294/6
=49
Answer:
See Explanation Below
Step-by-step explanation:
Question is incomplete.
(The height of the prism is missing and no attachment is provide)
However, I'll solve on a general rule.
Given
Volume of prism, V = 294in³
The volume of a prism is calculated multiplying the base area by the height of the prism.
Let's represent the base area by B and the height by H.
Mathematically,
V = B * H.
Make B the subject of formula
B = V/H
Substitute 294 for V.
The expression becomes
B = 294/H
Now, let's assume the height is 6 inches.
The expression for base area becomes
B = 294/6
B = 49 in²

y=
Answer:
y = -10/3x -23
Step-by-step explanation:
The 2-point form of the equation of a line is useful for this.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
Using your points, we have ...
y = (-3 -7)/(-6 -(-9))(x -(-9)) +7
y = (-10/3)(x +9) +7
y = -10/3x -23 . . . . . . . simplify
The equation of the line passing through the points (-9,7) and (-6, -3) is y = -10/3x -14.
Explanation:In mathematics, the equation of a line can be given as y = mx + c, where m is the slope of the line and c is the y-intercept. Firstly, we need to calculate the slope (m) which is (y2 - y1) / (x2 - x1). If we substitute the points (-9,7) and (-6, -3) we get (-3 - 7) / (-6 + 9) = -10 / 3, so m = -10/3. Next, to get the y-intercept (c) we can substitute the slope and one of the points into the equation: 7 = -(10/3)*(-9) + c, and we get c = -14. Therefore the equation of the line is y = -10/3x -14.

Mrs. Keen bought a new snow blower at Lowe's. It regularly is sold
for $565.00, but there was a sale that said it was 35% off. How much
did Mrs. Keen pay for her new snow blower? SHOW WORK!
Answer:
367.25 dollars
Step-by-step explanation:
To calculate 35 percent of 565 you would first
Find 30 percent to do this find 10% (÷10) and then times your answer by 3. (565÷10=56.5 times by 3 is 169.5)Then you would have to find 5 percent do this by halfing 10% of the number. (We know 10% equals to 56.5 half off that is 28.25)Add the numbers together (5% + 30%)(169.5 + 28.25 =197.75)35% is 197.75 the question says 35% off so you would have to take the 35% off the 565
(565-197.75 = 367.25)
Solve the following system of
equations:
y=47+ 3x
y=8+0.5x
The system of equations is solved by setting the two equations equal to each other and solving for x followed by solving for y using the obtained x value. The solution is x = -15.6 and y = 0.2.
Explanation:The student is asking to solve a system of two linear equations:
y = 47 + 3xy = 8 + 0.5xTo find the solution, we need to set the two equations equal to each other since they both equal y:
47 + 3x = 8 + 0.5x
Now, let's solve for x:
Subtract 0.5x from both sides: 47 + 2.5x = 8Subtract 47 from both sides: 2.5x = -39Divide both sides by 2.5: x = -39 / 2.5Calculate x: x = -15.6Now that we have x, we can solve for y using either of the original equations:
y = 8 + 0.5(-15.6)
Calculate y:
y = 8 - 7.8
y = 0.2
Therefore, the solution to the system of equations is x = -15.6 and y = 0.2.

Which measures of center and variability can be used to most accurately compare the two data sets? mean and MAD mean and IQR median and MAD median and IQR
Answer:
Median and IQR
Step-by-step explanation:
If we are to accurately compare two data sets, the best measure of central tendency is median and best measure of variability is the MAD.
The reason is that:
1. Median is not affected by outlier or extreme value. Due to this, if we use the mean, it can be misleading if there is any case of outlier(s) in the data sets.
2. The interquartile range (IQR) is the middle half of the data. It uses the concept of median to operate - think about the median value that splits the dataset in half. Similarly, you can divide the data into quarters. This also is not affected by outlier(s) or extreme value(s).
NB: When we say middle half or middle number, we assumed you have sorted the data sets either in ascending order or descending order. This will put the data sets in order of their sizes. E.g., 1 < 2 < 3, etc.
