Theres a number of passes to purchase
Normal price (without pass) is $6
If Seth goes to all 30 movies without pass he will spend
30x6 = $180 dollars
WITH the pass Seth have $30 dollars , then dividing by 2 , this means he can go to 30/2 = 15 movies in summer with pass
Then remains another 15 movies that he can vo WITHOUT PASS
in this 15 movies Seth spends 15x6= $90 dollars
add this to the $30 spent in the other 15 movie
it gives 30+90 = $120 dollars
Finally substract
$180- $120= $60 dollars he can save
Two angles in triangle PQR are congruent, ∠P and ∠Q; ∠R measures 36.25°. What is the measure of ∠Q?
143.75°
107.5°
71.875°
36.25°
Answer:
71.875
Step-by-step explanation:
p = q
180 - 36.25 = 143.75
p + q = 143.75
143.75 ÷ 2 = 71.875

Riley work 5 1/4 hours on Monday 3 3/8 hours on Tuesday and 2 and 5/6 hours on Wednesday he rounded the hours to 5,3,and two before adding them together to get 10 hours did he make a high or low estimate
First, let's convert the mixed numbers to fractions:
5 1/4 = 21/4 = 5.25
3 3/8 = 27/8 = 3.375
2 5/6 = 17/6 = 2.83333
5.25 + 3.375 + 2.83333 = 11.45833333
Therefore he made a low estimate

Please give me the correct answer.Please decide if these 4 statements is a function or not a function.
As according to given statement:
1). Each school has one principal so as there is a relation between school and principal so it is a function.
2). Each student has a unique student ID number: so as there are so many students and they allhave different unique student ID's so there is a function.
3). Shoe manufacturers make different type of shoes : so as there is relation but we can't describe a function between them.
4). Each month of the year has a total amount of rainfall measured in inches:
So it is a function between month and the rainfall measured in inches.

You travel 5 hours and 50 minutes. If you drove at an average of 41 mph, how much distance you traveled?
First, let's convert those 50 minutes into hours:
This way,
[tex]x=\frac{50\cdot1}{60}\Rightarrow x=0.83[/tex]I would have driven for 5.83 hours.
Using this, and the average pace (46 miles in one hour),
We get that:
[tex]x=\frac{46\cdot5.83}{1}\Rightarrow x=268.18[/tex]I would have traveled 268.18 miles
using the set of numbers find the mean rounded to the nearest tenth , median , mode and range.98 , 98 , 90 , 82 , 89 , 87
The median is defined as the sum of all the values divided by the total number of data, then in this case:
[tex]\begin{gathered} \mu=\frac{98+98+90+82+89+87}{6} \\ \mu=\frac{544}{6} \\ \mu=90.7 \end{gathered}[/tex]To find the median we need to order the data:
[tex]82,\text{ 87, 89, 90, 98, 98}[/tex]The median is the number that divides all the data in half, since we have an even number of data we need to take the mean between the middle data, that is, the median is:
[tex]\frac{89+90}{2}=89.5[/tex]The mode is the number that repeats itself more on the data set, then in this case we the mode is 98.
The range is the difference between the lowest and highest data, then:
[tex]98-82=16[/tex]Summing up we have:
mean: 90.7
median: 89.5
mode: 98
Range: 16

Explanation:Surface area of triangular prism = base × height + length ×perimeter of triangle
base = j = 150 units
height = h = 40 units
length = k = 85 units
m = 85 units
Perimeter of triangle = j + m + m
Perimeter of triangle = 150 + 85 + 85 = 320 units
Surface area of triangular prism = 150(40) + 85(320)
Surface area of triangular prism = 6000 + 27200

EXPLANATION:
Given;
We are told that a forest covers an area of 2300 square kilometers.
Next we are told that this forest area decreases by 7.75% each year.

root54 = root9 x root6
root24 = root4 x root6
(root16 x root6) - (root9 x root6) + (root4 x root6)

Identify the Sampling Method. Identify the sampling method (simple randomsampling, systematic sampling, convenience sampling, or stratified sampling) in the followingstudies. study of the use of antidepressants selects 50 participants between the ages of 20 and 29,50 participants between the ages of 30 and 39, and 50 participants between the ages of 40 and49.
Step 1
Analyze the Sampling method
In stratified sampling, the population is divided into two or more groups called strata according to some criterion such as geographic location, grade level, age, income, etc. Subsamples are randomly selected from each stratum. Elements within each stratum are homogenous but are heterogeneous across the strata. For example;
From this question, the general study is on the use of antidepressants. This is the strata, each stratum of 50 participants each based on age cuts across. They are homogenous in their individual stratum of age grades( 20-29), (30-39), (40-49) but are homogenous in the sense that 50 participants were chosen across all stratum and the study is generally about antidepressants.
Hence, the right answer is stratified sampling.
solving systems with subtraction y=7txy=3x+9
y = 7 + x
y = 3x + 9
To solve the simulataneous equation with subtraction,
Step 1: name the equations
y = 7 + x ---- equation 1
y = 3x + 9 ----- equation 2
Step 2: subtract equation 1 from 2
so that
y - y = (3 x -x ) + (9 - 7)
0 = 2x + 2
2x = - 2
divide oth sides by 2
x = -2/2
x = -1
To get y, substitute the value for x into equation 1
y = 7 + x
y = 7 + (-1)
y = 7-1 = 6
y = 6
hence the solution is (-1, 6)

The table below represents a linear function f(x) and the equation represents a function (x)f(x)-1-12g(x)09(x) = 2x + 610Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x), (6 points)Part B: Which function has a greater y-intercept? Justify your answer (4 points)I
Answer:
(a)The slope of f(x) is greater than the slope of g(x).
(b)g(x) has a greater y-intercept.
Explanation:
Part A
From the table of f(x), we have the pairs:
(-1,-12),(0,-6) and (1,0).
First, we find the slope of f(x).
[tex]\begin{gathered} \text{Slope}=\frac{Change\text{ in y-axis}}{Change\text{ in x-axis}} \\ =\frac{-6-0}{0-1} \\ =-\frac{6}{-1} \\ =6 \end{gathered}[/tex]Given the function g(x) defined as follows:
[tex]g(x)=2x+6[/tex]Comparing g(x) with the slope-intercept form (y=mx+b), the slope of g(x) is m=2.
Sentence: The slope of f(x) is greater than the slope of g(x).
Part B
The y-intercept is the point in a function where x=0.
In f(x), When x=0, f(x)=-6
• The y-intercept of f(x) is -6.
Comparing g(x) with the slope-intercept form (y=mx+b), the y-intercept of g(x), b=6.
Therefore, g(x) has a greater y-intercept.
In the parallelogram below, if AP = 45 and PC = 3x + 15, find x.
One of the properties of a parallelogram is that its diagonals bisect each other. This means that one diagonal cuts the second diagonal in equal length.
This means that AP = PC. If AP = PC, then 45 = 3x + 15.
[tex]45=3x+15[/tex]We can now find the value of x using the equation above.
First, subtract 15 on both sides of the equation.
[tex]45-15=3x+15-15[/tex][tex]30=3x[/tex]Then, divide both sides of the equation by 3 to isolate x.
[tex]\frac{30}{3}=\frac{3x}{3}[/tex][tex]10=x[/tex]Therefore, the value of x is 10. (Option B)
What is the probability of rolling a sum of six on a standard pair of six sided dice
The probability of rolling a sum of six on a standard pair of six sided dice is 0.139.
What is probability?
The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
When we rolled two dice, there were 36 possible results. Of those 36 results, 5 of them added up to 6, and they were: {1, 5}, {2, 4}, {3, 3}, {4, 2}, and {5, 1}.
Therefore, P(sum 6) = 5/36 = 0.1388888
With a typical pair of six-sided dice, the likelihood of rolling a sum of 6 is 0.139.
