Answer:
Coupon A is better by $2.80.
Step-by-step explanation:
You want to know how much better the best price is between coupon A's $55 rebate on $87 worth of pants, or coupon B's 60% off.
ReductionThe price reduction offered by coupon B is ...
0.60 × $87 = $52.20
ComparisonClearly, the $55 reduction offered by coupon A is a greater reduction than the $52.20 reduction offered by coupon B. The difference in value is ...
$55.00 -52.20 = $2.80
Coupon A gives the lower price by $2.80.

what would be themissing side length
Answers
The missing side length is 5.7.
What would be themissing side length?The missing side length AB, can be calculated using the Pythagorean Theorem.The Pythagorean Theorem states that in a right triangle, the sum of the squares of the lengths of the two sides adjacent to the right angle (A and B) is equal to the square of the length of the hypotenuse (C).In other words, AB^2 + BC^2 = AC^2.In this case, AB^2 = AC^2 - BC^2, or AB^2 = 6.7^2 - 3^2, which simplifies to AB^2 = 44.89.Taking the square root of both sides yields AB = 6.7.Therefore, the missing side length, AB, is 6.7.The missing side length of a triangle with sides of lengths a, b, and c is calculated by using the Pythagorean theorem, which states that a^2 + b^2 = c^2. In this case, we are given that side c is 3, and side a is 6.7.Using the Pythagorean theorem, we can solve for side b by rearranging the equation to read b^2 = c^2 - a^2. Plugging in our known values, we get b^2 = 9 - 44.89, or b^2 = -35.89.Since the square root of a negative number is not a real number, this implies that there is no real number solution for b, and therefore the missing side length of the triangle is not possible.

The volume of a cylinder is 542pi in?. The height of the cylinder is 16 in. What is the radius of the cylinder to the nearest hundredth?
The volume of a sphere is 5,055pi m. What is the surface area of the sphere to the nearest square meter?
Answers
Answer:
I. Radius, r = 5.82 in
II. S.A of a sphere = 19.61 meters
Step-by-step explanation:
Given the following data;
I. Volume of cylinder = 542π in³
Height = 16 in
To find the radius of the cylinder;
Volume of cylinder = πr²h
542π = πr²*16
Dividing both sides by π, we have;
542 = 16r²
r² = 542/16
r² = 33.875
Radius, r = 5.82 in
II. Volume of sphere = 5.055π m³
To find the surface area of the sphere;
First of all, we would find the radius of the sphere.
[tex] Volume \; of \; a \; sphere = \frac {4}{3} \pi r^{3} [/tex]
Substituting into the formula, we have;
[tex] 5.055 \pi = \frac {4}{3} \pi r^{3} [/tex]
Cross-multiplying, we have;
[tex] 5.055 \pi * 3 = 4 \pi r^{3} [/tex]
[tex] 15.165 \pi = 4 \pi r^{3} [/tex]
Dividing both sides by 4π, we have;
[tex] 3.79 = r^{3} [/tex]
Taking the cube root of both sides, we have;
r = 1.56 m
Next, we find the surface area (S.A) of the sphere;
S.A of a sphere = 4πr
S.A of a sphere = 4*3.142*1.56
S.A of a sphere = 19.61 meters

What is a piecewise function?A piecewise function is a function that is defined on a sequence of intervals. A common example is the absolute value function. Piecewise functions are implemented in the Wolfram Language as PiecewiseAdditional piecewise functions include the Heaviside step function, rectangle function, and triangle function.Given is the absolute value function -
f(x) = 1/2 |x|
We can write it as a piecewise function as follows. The given function is as follows :
f(x) = 1/2 |x|
The absolute value function is given as -
|x| = - x {x < 0}
|x| = x {x ≥ 0}
So, we can write the piecewise function as -
1/2 |x| = {- x/2} {x < 0}
1/2 |x| = {x/2} {x ≥ 0}
Therefore, the piecewise function f(x) = 1/2 |x| is equivalent to -

What is the expected value of the following game?
Pay $8. Win $100 if we draw a King from a standard deck. Win nothing if we draw something else.
Answers
Answer: Expected Value = -0.31
We expect to lose about 31 cents each time we play the game.
============================================================
Explanation:
A = event of selecting a king
B = event of not selecting a king
P(A) = 4/52 since there are 4 kings out of 52 total. This fraction reduces to 1/13.
P(B) = 48/52 = 12/13
Note: P(A) + P(B) = 1.
V(A) = net value of selecting a king
V(A) = 100-8 = 92, so you net $92 if event A occurs.
V(B) = -8, meaning you lose 8 dollars if you select anything but a king
We multiply the probability values with their corresponding net values
P(A)*V(A) = (1/13)*(92) = 7.07692 approximately
P(B)*V(B) = (12/13)*(-8) = -7.38462 approximately
Add up the results:
7.07692 + (-7.38462) = -0.3077
The expected value is approximately -0.3077 which rounds to -0.31
We expect to lose on average 31 cents each time we play the game. The nonzero expected value means this is not a mathematically fair game.

By solving system of linear equation we get Cost for 1 cheeseburger $5 and 1 cups of lemonade $2
What is a system of linear equations?A system of linear equations is a collection of two or more linear equations that have the same variables. A linear equation is an equation in which the highest power of the variable is 1. In other words, the equation is a straight line when graphed.
Here is an example of a system of linear equations:
3x + 2y = 19
2x + 4y = 18
This is a system of equations problem, where we can use the information provided to set up two equations and then solve for the unknown variables. Let x be the cost of one cheeseburger and y be the cost of one cup of lemonade.
From the information provided, we know that:
3x + 2y = 19 (the cost of 3 cheeseburgers and 2 cups of lemonade is $19)
2x + 4y = 18 (the cost of 2 cheeseburgers and 4 cups of lemonade is $18)
To find the cost of one cheeseburger and one cup of lemonade, we can solve this system of equations. One way to do this is by substitution.
3x + 2y = 19
we get
[tex]x=\frac{19-2y}{3}[/tex]
substituting x in equation 2x+4y=18
we get
[tex]2(\frac{19-2y}{3})+4y=18[/tex]
[tex]38 - 4y + 12y = 54\\8y = 16\\y = 2[/tex]
substituting y in equation 3x+2y=19
[tex]3x+2(2)=19\\3x=19-4\\3x=15\\x=5[/tex]
The cost of one cup of lemonade is $2
The cost of one cheeseburger is $5

A manufacturer produces soda cans and a quality control worker randomly selects two cans from the assembly line for testing. Past statistics show that 10% of the cans are defective. What is the probability that the two selected cans are defective if the quality control worker selects the two cans from a batch of 60 cans?
Answers
Answer:
It would be 1%
Step-by-step explanation:
First of all, note that any of the cans with the batch have the same chance at being defective, so ingore that. However, note the chance that each one is defective:
10%
So if you picked up any can, it would have a 10% chance of being defective. With this, by picking up two cans, you would do:
0.1 * 0.1 = 0.01
To find the chance of both cans being defective, being 1% for both of the selected cans being defective.

a) Multiplicative inverse
if the product the given number and reciprocal of the given number is 1.
so,
5 * 1/5 = 1
as LHS = 5 * 1/5 = 1

Hence , a - 4
b ) Additive inverse
if the summation of the given number and opposite sign of given number results 0 .
7 + (-7) = 0
LHS = 7+ (-7) = 0
RHS = 0
hence , b - 5
c ) Commutative Property of Multiplication
if a.b = b.a hence it is in Commutative Property of Multiplication .
so, 5.6 = 6.5
hence , c - 1
d) Distributive property
if a ( b + c ) = a*b + a*c than it is in distributive property .
hence , d - 6
e) Additive Identity Property
if a+ 0 = a hence it is Additive Identity Property
so , b - 2

Step-by-step explanation:
From the given diagram;
arcPSU = arcPQ + arcQR + arcRS + arcST + arcTU
Given
arcPQ = arcTU
arcQR = arcRS = 37
arcAST = 90
Since 136 + arcPQ + 37+37+90+arcTU = 360
136+2arcPQ+ 37+37+90= 360
2arcPQ+300 = 360
2arcPQ = 360 - 300
2arcPQ = 60
arcPQ = 60/2
arcPQ = 30degrees
Substitute into the above expression
arcPSU = arcPQ + arcQR + arcRS + arcST + arcTU
arcPSU = 360 - arcPU

Aregular decagon has a radius of 8 cm. What is the approximate area of the decagon?
Answers
Using a calculator we can approximate this to be A ≈ 568.89 cm^2.
What is regular decagon?A regular decagon is a two-dimensional geometric shape with ten sides of equal length and ten interior angles of equal measure. It is a polygon, which is a two-dimensional shape made up of line segments (straight sides).
The approximate area of a regular decagon can be calculated using the formula A = (5/2) * a^2 * tan(π/5), where a is the length of each side. Since the radius of the decagon is 8 cm, the length of each side can be calculated using the formula a = 2r * sin(π/10) where r is the radius.
Plugging these values into the formula we get A = (5/2) * (2 * 8 * sin(π/10))^2 * tan(π/5) which simplifies to A = 320 * sin^2(π/10) * tan(π/5).
Using a calculator we can approximate this to be A ≈ 568.89 cm^2.
