Answer:
[tex]54[/tex]
Step-by-step explanation:
[tex]Let\ the\ first\ digit\ of\ the\ two\ digit\ number\ be\ a\\Let\ the\ second\ digit\ of\ the\ two\ digit\ number\ be\ b\\Hence,\\We\ are\ given\ that,\\a+b=9\\Hence,\\b=(9-a)\\As\ we\ know\ that,\\The\ original\ number\ containing\ 2-digits\ can\ be\ written\ as: 10a+b\\Hence,\\The\ original\ number=10a+(9-a)\\The\ original\ number=9a+9\\\\[/tex]
[tex]Now,\\Lets\ consider\ the\ reversed\ number\ with\ the\ reversed\ digits\ of\ the\\ original\ number.\\Hence,\\Reversed\ number\ containing\ reversed\ digits\ can\ be\ written\ as:10b+a\\Hence,\\Reversed\ number=10b+a\\Reversed\ number=10(9-a)+a=90-10a+a=90-9a\\[/tex]
[tex]Now,\\We\ are\ given\ that,\\Original\ Number-9=Reversed\ number\\Or,\\Original\ Number-Reversed\ number=9\\Hence,\\9a+9-(90-9a)=9\\9a+9-90+9a=9\\18a=90\\a=\frac{90}{18}=5[/tex]
[tex]As\ a=5, b=(9-5)=4\\Hence,\\The\ original\ number=10a+b=10*5+4=50+4=54[/tex]

The juniors and seniors at a high school are ordering class shirts. The amounts ordered in each size are shown in the two-way frequency table below.
Small Medium Large X-Large Total
Juniors 65 84 68 23 240
Seniors 51 62 79 28 220
Total 116 146 147 51 460
Which statement is true about the information represented in the table?
A The percentage of Seniors who ordered a large shirt is greater than the percentage of students who ordered a large shirt who are also in the Senior class.
B The percentage of Seniors who ordered a small shirt is the same as the percentage of students who ordered a small shirt who are also in the Senior class.
C The percentage of Juniors who ordered a medium shirt is greater than the percentage of students who ordered a medium shirt who are also in the Junior class.
D The percentage of Juniors who ordered a medium shirt is less than the percentage of students who ordered a medium shirt who are also in the Junior class.
Answer:
it b
Step-by-step explanation:
To determine which statement is true, we need to calculate the percentages for each option and compare them and option c is correct.
Option A: The percentage of Seniors who ordered a large shirt is greater than the percentage of students who ordered a large shirt and are also in the Senior class. To calculate the percentage of Seniors who ordered a large shirt, we divide the number of Seniors who ordered a large shirt by the total number of Seniors:
Percentage of Seniors who ordered a large shirt =[tex](79 / 220) * 100 = 35.91[/tex]% To calculate the percentage of students who ordered a large shirt and are also in the Senior class, we divide the number of Seniors who ordered a large shirt by the total number of students who ordered a large shirt: Percentage of students who ordered a large shirt and are also in the Senior class [tex]= (79 / 147) * 100 = 53.74[/tex]% Since the percentage of students who ordered a large shirt and are also in the Senior class is greater than the percentage of Seniors who ordered a large shirt, statement A is false.
Similarly, we can calculate the percentages for the other options: Option B: The percentage of Seniors who ordered a small shirt is the same as the percentage of students who ordered a small shirt and are also in the Senior class. Percentage of Seniors who ordered a small shirt [tex]= (51 / 220) * 100 = 23.18[/tex]% Percentage of students who ordered a small shirt and are also in the Senior class [tex]= (51 / 116) * 100 = 43.97[/tex] % Since the percentages are not the same, statement B is false.
Option C: The percentage of Juniors who ordered a medium shirt is greater than the percentage of students who ordered a medium shirt and are also in the Junior class. Percentage of Juniors who ordered a medium shirt [tex]= (84 / 240) * 100 = 35[/tex]% Percentage of students who ordered a medium shirt and are also in the Junior class [tex]= (84 / 146) * 100 = 57.53[/tex]% Since the percentage of students who ordered a medium shirt and are also in the Junior class is greater than the percentage of Juniors who ordered a medium shirt, statement C is true.
Hence the correct option is C.

101010 glow wands for \$65$65dollar sign, 65
9514 1404 393
Answer:
6 for $37.50 has the same price
Step-by-step explanation:
The price per wand is found by dividing the price by the number of wands.
8 for $50 ⇒ $50/8 = $6.25 per wand
__
4 for $20 ⇒ $20/4 = $5.00 per wand not the same
6 for $37.50 ⇒ $37.50/6 = $6.25 per wand is the same price
10 for $65 ⇒ $65/10 = $6.50 per wand not the same

Step-by-step explanation:
can someone solve a - 3 over 7 s = -8
and a + 24 = -15
STEP BY STEP PLEASE.
Answer:
a=-39; s=0.75
Step-by-step explanation:
Solve the System of Equations by Substitution.
First, solve one of the equations for a variable. I'll do the 2nd one because it only has one variable.
a+24=-15 -------> a=-39
Now we know what a is just plug it back into the other equation and get s.
[tex]\frac{a-3}{7s} =-8[/tex]
[tex]\frac{-39-3}{7s} =-8[/tex]
[tex]\frac{-42}{7s} =-8[/tex]
Switch the -8 and 7s
[tex]\frac{-42}{-8} =7s[/tex]
Simplify the fraction
5.25=7s
Divide by 7 to isolate the s
0.75=s
Answer:
2)a+24=-15
a=-15-24
a=-39

The tables represent the functions f(x) and g(x).
Which input value produces the same output value for the two functions?
x = –12
x = –9
x = –6
x = –3
Answer:
x = -6 has the same output for both functions
Step-by-step explanation:
Here, we want to get the x value that has the same y-value for both functions
We can simply get this by substituting
Let’s take it one after the other
if x = -12
f(x) = 2/3(-12) + 7
= -8 + 7 = -1
2(-12) + 15 = -9
This is incorrect
for x = -9
g(x) = 2/3(-9) + 7
= -6 + 7 = 1
f(x) = 2(-9) + 15 = -3
for x = -6
g(x) = 2/3(-6) + 7 = 3
f(x) = 2(-6) + 15 = 3
So as we can see our answer is x = -6

In a science test. Devi scores 16 marks more than Ali. lf
Devi obtains twice as many marks as ali find the marks Ali obtains.
Let the marks of Devi be x and Ali be y.
So, the equations:
2y = x and y + 16 = x
So,
2y = y + 16. [ because we know equals are equal to equals]
=> 2y - y = 16
=> y = 16
Check
Ali's marks are half of Devi's marks.
Devi's marks are 16 more than alis.
So, Devi's marks will be 16×2 = 32 and 32 is 16 greater than 16 (16+16=32).

Answer:
x = 8
y = 14
Step-by-step explanation:
It's given in the question,
ΔABC ≅ ΔDEF
Therefore, by the property of congruence,
EF = BC, AB = ED and AC = FD
And m∠E = m∠B
Since, m∠E = m∠B
(6y - 4) = 80
6y = 80 + 4
6y = 84
y = 14
Since, AB = ED
10 = 3x - y
10 = 3x - 14
3x = 24
x = 8
what is the birthday polynomial project for 05/11/2004?
Answer:
OBJECTIVE: To create, characterize and graph a polynomial function that reflects you!
PROCESS:
1. Write, IN ORDER, the digits of the month (1 or 2 digits), day (1 or 2 digits), and year (4 digits) of your birthday.
For example, April 2, 1976 could be “421976” or “4021976”. Use must use 6, 7 or 8 digits.
2. Create a polynomial using your digits, in order. Again, for example, my polynomial could be:
() = 4
5 + 2
4 − 1
3 − 9
2 + 7 −6 or
() = 4
6 + 2
4 − 1
3 − 9
2 + 7 − 6
*notice in the second example, the 0 eliminated the 5th degree term
**if your birth year is 2000, you may change your constant term (the “lagger”, which is the 6 in my
equation) to your favorite number, instead of 0.
3. Experiment with the shape of your birthday polynomial by changing the signs (+/-) of various terms in your
calculator. Try to create a polynomial function with an interesting shape and some turning points. Be creative!
You’re trying to express yourself in this graph!
*notice the change in the 2 graphs
below by just changing 3 positive
signs to negative!
4. Analyze your polynomial (using your calculator)
by finding these characteristics:
a. Roots (x-intercepts)
b. Y-intercept
c. Relative minimums and maximums
d. End behavior
e. Points (x, y)
PRODUCT: Make a presentation of your polynomial. Be creative! Be colorful! Be neat! Be artistic and ACURATE! Just
meeting the basic requirements will earn you a 90% (at most). At a minimum, your presentation should include a visual
representation of the graph of your polynomial and should also include the following:
□ The statements: My Birthday is ________________
My Birthday Polynomial is ______________________.
□ A T-chart with 10 (x, y) points
□ All Roots (labeled on graph and values)
□ Y-intercept (labeled on graph and value)
□ Relative Maximum and Minimums (labeled on graph and values)
□ Sentence description of end behavior and why this occurs
ASSESSMENT: Your project will replace lowest MID-CHAPTER QUIZ (30 points). You will be graded on completion of all
requirements and accuracy of graph and values. Additional points (90% and above) will be awarded for creativity and
effort.
