On the first day of summer break, Katie and her friends go to the theater to see the latest action movie, Dark Emperor: Fist of Vengeance. After Katie buys a ticket, she also buys a bucket of popcorn and a soda for $9.25. In all, Katie spends $23.25 at the movie theater. Which equation can you use to find the cost c of Katie's ticket?
We have the following information:
c is the cost of Katie's ticket; a bucket of popcorn and a soda cost $9.25, we determine c by using the following expression:
[tex]c=23.25-9.25\Rightarrow c=14[/tex](This assuming there is no additional information).

Enter an inequality that represents the graph in the box.
The inequality that represents the graph is (1/4)x - y + 3/2 ≤ 0.
What is inequality?An inequality compares two non-qual objects.
We know the general equation of a line is ax + by + c = 0.
From observation, we can conclude that the given line has points (0, -6) and (2, 2).
∴ The slope of the line is [tex]\frac{y_2 - y_1}{x_2- _ x_1}[/tex].
= (0 - 2)/(-6 - 2).
= -2/-8.
= 1/4.
∴ Equation of the line in slope intercept form y = mx + b.
2 = (1/4)(2) + b.
2 = 1/2 + b.
b = 3/2.
∴ Equation of the line is y = 1/4(x) + 3/2.
(1/4)x - y + 3/2 = 0 but the region will be (1/4)x - y + 3/2 ≤ 0.

A textbook store sold a combined total of 217 sociology and history textbooks in a week. The number of history textbooks sold was 77 less than the number of
sociology textbooks sold. How many textbooks of each type were sold?
Answer:
there were 246 chemistry textbooks and 169 psychology textbooks sold
Step-by-step explanation:
Let
c = the number of chemistry textbooks sold
p = the number of psychology textbooks sold
a textbook store sold a combined total 415 chemistry and psychology textbooks in a week
c + p = 415
the number of chemistry textbooks sold was 77 more than the number of psychology textbooks sold
c = 77 + p
by solving the system of equations
c + p = 415
c = 77 + p
we find
c = 246 chemistry textbooks
p = 169 psychology textbooks

Suppose r varies directly as the square of m, and inversely as s. If r equals 16when m equals 9 and s equals 9, find r when m equals 27 and s equals 9.
Answer:
144
Step-by-step explanation:
r = k m^2 / s <====given ( k is proportionality constant)
16 = k ( 9^2) / 9 shows k = 1 7/9
then:
r = 1 7/9 * 27^2 / 9 = 144
Explain why the volume of these two stacks of quarters are equal? Use Cavaliens principle in your explanation (If you need to)
Given the word problem, we can deduce the following information:
1. Two stacks of 18 pennies each are shown.
To determine if the volumes of the given stacks of quarters are equal, we note that Cavelieri's Principle states:
The volumes of two solids are equal if the areas of the corresponding sections drawn parallel to some given plane are equal.
Since each penny in both stacks has the same base area and has the same number of pennies. Therefore, the volumes of the given stacks are equal.

6ft , 5ft , c. What is the length of the hypotenuse
The length of the hypotenuse of the triangle is √61 ft
How to determine the length of the hypotenuse?From the question, we have the following parameters that can be used in our computation:
Smaller sides = 6ft and 5 ft
Hypotenuse = c
The hypotenuse of a triangle is calculated using the following Pythagoras theorem
Hypotenuse^2 = Opposite^2 + Adjacent^2
Where Opposite and Adjacent are 6 and 5
So, we have
c^2 = 5^2 + 6^2
Evaluate
c^2 = 61
Take the square roots
c = √61
Hence, the hypotenuse is √61 ft

6 men complete the work in 20 days.
In 1 day it takes:

Step-by-step explanation:
Customers of a phone company can choose between two service plans for long distance calls. The first plan has a $26 monthly fee and charges an additional0.09 for each minute of calls. The second plan has a $19 monthly fee and charges an additional $0.13 for each minute of calls. For how many minutes of callswill the costs of the two plans be equal?
First Plan
Monthly fee = $26
charge per min = $0.09
Second Plan
Monthly fee = $19
charge per min = $0.13
Solution
Let the number of minutes spent on calls in a specific month be x
The total cost spent using the first plan:
[tex]0.09x\text{ + 26}[/tex]The total cost spent using the second plan:
[tex]0.13x\text{ + 19}[/tex]If the cost from the first plan would be equal to that of the second plan:

Determining the equivalent numberGiven digit:
1,0 0 0,0 0 0
Hence,
When something is equivalent to another things it implies or means that both of them are the same or correspond.
We know that 1,000,000 can be re- write as 1 Million and 1000 Thousands.
Now let determine or find the equivalent of 1,000,000 using scientific notation

Scientific notation = 10^6
Based on the above 10^6 is equivalent to 1,000,000. We can justified it by pressing 10^6 on our calculator which will in turn gives us 1,000,000.
So,
1,000,000 = 10^6
Therefore we can conclude that the correct option is C based on the fact that 10 raise to power of 6 is the same as 1,0 0 0,0 0 0.
