Answer:
m<1=140
m<2= 40
m<3= 140
m<4= 40
m<5=140
m<6= 40
m<7= 140
Answer:
Step-by-step explanation:
m∠1 = 180-40= 140° (suplementary angles)
m∠2= 40° (vertical angles are ≅)
m∠3= 140° ( is ≅ to ∠1)
m∠4 = m∠6 = 40° ( same side corresponding ∠s, and vertical angles)
m∠5 = m∠7 = 140° ( same side corresponding ∠s, and vertical angles)

Find the values of x and y that satisfy both the equations
12x + 3y = 15 and 2x – 3y = 13.
Answer:
X=1 and Y=1 in the first question
Step-by-step explanation:
simply 12X means 12*x, so x=1 and 12*1+3*1=15 question 1
and question 2
2X means 2*X x=8 so 2*8=16 so 16-3 because Y=1 and
16-3=13

Sean tried to drink a slushy as fast as he could. He drank 5 milliliters of slushy each second and finished all
the slushy after 50 seconds.
Graph the relationship between the amount of slushy left in the cup (in milliters) and time (in seconds).
Answer:
graph like this:
Step-by-step explanation:
First, in 5 seconds, we know that he drinks 25 mL of slushy. We know this because 1 second is 5 mL, so 5 seconds is 25 mL. So, your graph should be going from the 5 second to 25 mL mark, then the 10 second and 50 mL mark, then the 15 mL and 75 mL mark, and so on.
Approximately how many years will it take $3000 to double if it is invested in an account that pays 3%
compounded monthly? Round your answer to the nearest whole year.
Answer:
24 years
Step-by-step explanation:
Total = start*(1 + interest rate / amount of times compounded per month)^(years*amount of compounds per year)
6000 = 3000*(1+0.03/4)^(4x)
6000 = 3000* ((403/400)^4)^x
2 = ((403/400)^4)^x
x = log base-((403/400)^4) of 2 = x
x = 23.19
rounding down 23 years (but you probably want a year over that to get at least 6000, so 24)

A) 7/2 x 1/3
B) 7/2 x 3/1
C) 6/2 x 1/3
D) 7x3
Hurry !!
Answer:
The question [tex]3\frac{1}{2}\div\frac{1}{3}[/tex] after change the mixed number to improper & using KCF will become : [tex]\mathbf{=\frac{7}{2}\times \frac{3}{1}}[/tex]
Option B is correct option.
Step-by-step explanation:
We need to change the mixed number to improper & use KCF to rewrite the question.
The expression is: [tex]3\frac{1}{2}\div\frac{1}{3}[/tex]
First converting mixed fraction into improper fraction
Multiply whole number with the denominator i,e (3*2=6) now add the numerator i.e (6+1) = 7/2
Solving:
[tex]3\frac{1}{2}\div\frac{1}{3}\\=\frac{7}{2}\div\frac{1}{3}[/tex]
Using KCF
KCF stands fro Keep it, Change it, Flip it.
It is used when division sign is converted to multiplication the term (1/3) is reversed to (3/1)
So, our expression will be
[tex]=\frac{7}{2}\times \frac{3}{1}[/tex]
So, The question [tex]3\frac{1}{2}\div\frac{1}{3}[/tex] after change the mixed number to improper & using KCF will become : [tex]\mathbf{=\frac{7}{2}\times \frac{3}{1}}[/tex]
Option B is correct option.

Raul received a score of 80 on a history test for which the class mean was 70 with standard deviation 10. He received a score of 75 on a biology test for which the class mean was 70 with standard deviation 2.5. On which test did he do better relative to the rest of the class?
Answer:
Raul performed better in the biology test
Step-by-step explanation:
Given
History
[tex]Score = 80[/tex]
[tex]Mean = 70[/tex]
[tex]Standard\ Deviation = 10[/tex]
Biology
[tex]Score = 75[/tex]
[tex]Mean = 70[/tex]
[tex]Standard\ Deviation = 2.5[/tex]
Required
Where did he perform better relative to other students
To do this, we simply calculate the z score in both tests and make comparison.
z score is calculated as thus;
[tex]z = \frac{x - Mean}{SD}[/tex]
For history;
[tex]z = \frac{80 - 70}{10}[/tex]
[tex]z = \frac{10}{10}[/tex]
[tex]z = 1[/tex]
For biology;
[tex]z = \frac{75 - 70}{2.5}[/tex]
[tex]z = \frac{5}{2.5}[/tex]
[tex]z = 2[/tex]
Since the z score in the biology test is greater than that of the history test, then he performed better in the biology test

The bill for Mr. Wilson’s diner meal is $25.50. As a tip, Mr. Wilson gives the server 20% of the meal’s cost. What is the total amount Mr. Wilson’s pays, including tip?
Answer:
$30.60
Step-by-step explanation:
What we know:
The bill for Mr. Wilson's diner meal is $25.50.
He gives a 20% tip to the waiter.
To figure out this tip, multiply 1/5 by 25.5.
1/5 * 51/2
51/10 = $5.10 tip.
Here, it's asking for the total, including the $5.10 tip. So, add $5.10 to $25.50 for $30.60 total, including the tip.
(For a simpler method *multiply 6/5 by $25.5)

(a) Determine the difference of outputs of any two inputs that are 1 unit apart. Show your work.
(b) Determine the difference of outputs of any two inputs that are 2 units apart. Show your work.
(c) Determine the difference of outputs of any two inputs that are 3 units apart. Show your work.
(d) What do you notice about the ratios of the differences in the outputs to the input intervals? Explain
your answer.
The ratio of the difference in outputs to the input interval is constant and equal to -8. This indicates that the function is a linear function with a slope of -8.
What is Algebraic expression ?
Algebraic expression can be defined as combination of variables and constants.
To find the differences of outputs for different input intervals, we can use the given function and the values in the table.
(a) The inputs that are 1 unit apart are -1 and 0. The corresponding outputs are f(-1) = -3 and f(0) = -11. The difference in outputs is:
f(0) - f(-1) = (-11) - (-3) = -8
Therefore, the difference of outputs of any two inputs that are 1 unit apart is -8.
(b) The inputs that are 2 units apart are -2 and 0. The corresponding outputs are f(-2) = 5 and f(0) = -11. The difference in outputs is:
f(0) - f(-2) = (-11) - 5 = -16
Therefore, the difference of outputs of any two inputs that are 2 units apart is -16.
(c) The inputs that are 3 units apart are -3 and 0. The corresponding outputs are f(-3) = 13 and f(0) = -11. The difference in outputs is:
f(0) - f(-3) = (-11) - 13 = -24
Therefore, the difference of outputs of any two inputs that are 3 units apart is -24.
(d) We can observe that the ratios of the differences in the outputs to the input intervals are constant, indicating that the function is linear. For example:
The ratio of the difference in outputs for inputs that are 1 unit apart to the input interval is:
-8 / (0 - (-1)) = -8 / 1 = -8
The ratio of the difference in outputs for inputs that are 2 units apart to the input interval is:
-16 / (0 - (-2)) = -16 / 2 = -8
The ratio of the difference in outputs for inputs that are 3 units apart to the input interval is:
-24 / (0 - (-3)) = -24 / 3 = -8
Therefore, the ratio of the difference in outputs to the input interval is constant and equal to -8. This indicates that the function is a linear function with a slope of -8.

How do I use the Descartes Rule of Signs to determine all possible number of positive and negative zeros?
f(x)= x^4-2x^3-4x^2+2x+3
Answer:
We conclude that:
2 or 0 positive real roots2 or 0 negative real rootsStep-by-step explanation:
Descartes Rule states that if the terms of a single-variable polynomial with real coefficients are ordered by descending variable exponent, then the number of positive roots of the polynomial is:
Either equal to the number of sign differences between consecutive nonzero coefficients, Or is less than it by an even number.Given the function
[tex]f\left(x\right)=x^4-2x^3-4x^2+2x+3[/tex]
So, the coefficients are 1, −2, −4, 2, 3
As can be seen, there are 2 changes.
This means that there are 2 or 0 positive real roots.
To find the number of negative real roots, substitute x with -x in the given polynomial:
[tex]x^4-2x^3-4x^2+2x+3[/tex] becomes [tex]x^4+2x^3-4x^2-2x+3[/tex]
The coefficients are 1, 2, −4, −2, 3
As can be seen, there are 2 changes.
This means that there are 2 or 0 negative real roots.
Therefore, we conclude that:
2 or 0 positive real roots2 or 0 negative real rootssolve the system using the elimination method. write solution as a orders pair.

Answer:
( [tex]\frac{22}{7}[/tex] , [tex]\frac{44}{7}[/tex] )
Step-by-step explanation:
3x + 2y = 22 ....... (1)
- x+ 4y = 22 ........ (2)
3 × (2) + (1)
(3x - 3x) + (2y + 12y) = 22 + 66 ( variable "x" is eliminated )
14y = 88
y = [tex]\frac{44}{7}[/tex]
- x + 4( [tex]\frac{44}{7}[/tex] ) = 22
x = [tex]\frac{176}{7}[/tex] - [tex]\frac{154}{7}[/tex] = [tex]\frac{22}{7}[/tex]
( [tex]\frac{22}{7}[/tex] , [tex]\frac{44}{7}[/tex] )
