Find the following angle measures. mAngleEAD = ° mAngleCAB = °
Answers
Answer:
Step-by-step explanation:
Oh the good ol CAB and EAD angles, well know angles from Greek lore, about the monsters CAB and EAD that were at opposing sides to the battle of Mythical Math, In the story they fight for 100 years.. so that's what the mythical angle of CAB was know as, While EAD was very hot headed and would fight at the drop of a hat, so he was known as the 45° centigrade fighter. Yes that's centigrade , not Celsius. while most people think that Centigrade and Celsius are the same thing, it's recently been discovered that Centigrade is a bit hotter. so you can add a few degrees to most angles when you are talking about EAD angles. not less the 3 but no more than 7 , so both of these angles can't really be known .. mostly b/c you didn't put a picture that everyone could see :/ So you got the Greek lore answer, that makes zero sense, just like your question :DDDDD

How many inches of lace will Sharon need to cover the edge of the mirror exactly once?
A. 3.82 in.
B. 18.84 in.
C. 37.68 in.
D. 75.36 in.
Answers
Answer:
37.68in
Step-by-step explanation:
Circumference = πd
d is the diameter = 12in
To get the number of lace that will cover we will find the circumference
C = 12 * 3.14
C = 37.68in
Hence the amount of lace needed is 37.68in

find the slope of the line through each pair of points (19,-2) (-11,10)
Answers
Answer:
[tex]\huge\boxed{-\frac{2}{5}}[/tex]
Step-by-step explanation:
The slope of a line can be determined from two points via the slope formula. This is usually defined as the change in y divided by the change in x. It’s commonly represented using this formula:
[tex]\displaystyle \frac{\Delta y}{\Delta x}[/tex]Where [tex]\Delta[/tex] represents “change in.”
The slope is basically just saying the rate of increase/decrease a function has when x increases by 1 - how much does y change when x increases by 1? We can find this by taking larger values and dividing by the rate at which we took the larger values. This derives the slope formula.
We can find the change in y and x in this function by analyzing the two points given. If we look at the change between each point, we can get the change since this is a line and thus has a constant slope.
The change in y will be 12. This is because from -2 to 10 is 10 units - [tex]10 - (-2) = 12[/tex] The change in x will be -30. This is because from 19 to -11 is -30 units - [tex]-19 -11 = -30[/tex]Now that we have our change in x and y, we can substitute these values into the slope formula.
[tex]\displaystyle \frac{\Delta y}{\Delta x}[/tex] [tex]\displaystyle \frac{12}{-30}[/tex] [tex]\displaystyle -\frac{12}{30}[/tex] Simplify - divide numerator and denominator by 6 [tex]\displaystyle -\frac{2}{5}[/tex]Therefore, the slope of this line is [tex]-\frac{2}{5}[/tex].

Students in an Algebra 1 class will perform the following experiment and then model it mathematically. They begin with 128 two-colored counters (a chip that has a yellow side and a red side) in a bag and complete the following steps:
Pour the counters from the bag onto the floor.
Count the number of counters that land on yellow.
Record the trial number and the number of counters that landed on yellow.
Put the counters that landed on yellow back into the bag and leave the rest on the floor (off to the side).
Steps 1 to 4 constitute one trial of the experiment. Repeat trials until no counters land on yellow.
Question 1
POSSIBLE POINTS: 1
Part A
Select the equation that best represents f(n), the number of yellow counters that land on yellow (and are put back into the bag) at the end of trial n, when n≥1?
A f(n)=128(12)nf of n is equal to 128 times 1 half to the n th power
B f(n)=128−12nf of n is equal to 128 minus 1 half n
Question 2
Part B
How many trials would the students most likely need to run until exactly one counter lands yellow side up (and is put into the bag)? Use mathematics to justify your response.
Answers
The number of counters is an illustration of a linear function
The number of counters that land on yellow is: [tex]f(n) = 128 - \frac 12n\\[/tex]The students need 254 trials to have one yellow side upHow to determine the equation
The number of counters is given as:
Count = 128
Each counter is two-colored (i.e. 1/2 yellow and 1/2 red)
So, the equation that represents the number of counters that land on yellow is:
[tex]f(n) = 128 - \frac 12n\\[/tex]
The number of trials to have one yellow side upWhen one yellow side is up, we have:
f(n) = 1
So, we have:
[tex]1 = 128 - \frac 12*n[/tex]
Subtract 128 from both sides
[tex]-127 = - \frac 12*n[/tex]
Multiply both sides by -2
[tex]n =254[/tex]
Hence, the student needs 254 trials to have one yellow side up

Step-by-step explanation:
The zeros of the function are written in the form

Your local dry cleaners is running a special. The dry cleaner is offering a 13% discount for any drop off that is over $40. Also, they are running a neighborhood special of an additional 5% off. Given this information, determine the decay factor corresponding to each percent decrease.

c.

b.
0.384; 0.3306
d.
87; 95
Answers
Answer:
a. 34.8; 33.06
Step-by-step explanation:
The computation is shown below;
since in the question it is mentioned that that if the price is $40 so if offered the 13% discount
So the 13% discount on $40 is
= $40 - 13% of $40
= $34.80
Now additional 5% is also provided
So,
= $34.80 - 5% of $34.80
= $33.06

What is0.54¯¯¯¯ expressed as a fraction in simplest form?
Enter your answer in the box.
Answers
Answer:
0.54 as a fraction is 54/100 and simplified it would be 27/50
Answer:
27 / 50
Step-by-step explanation:
You can find this out by re-stating it as 54 / 100 and removing common factors between the numerator and denominator. In this case, only the number 2 can be factored out:
54 / 100
= 27 / 50
27 is a perfect cube (three cubed), and 50 is not divisible by 3, so we can't factor it further.
