Beth has 250 comic books in her collection. She begins to sell 20 of them each week. Martin has 80 comic books in his collection. He begins buying 15 new comic books each week. Select from the choices below, dragging and dropping to build an inequality that could be used to determine when Martin's comic book collection exceeds Beth's.
Answer:
250 - 20 < 80 + 15x
Step-by-step explanation:
Given that
Beth has 250 books and 20 books sold each week
While on the other hand, Martin has 80 books and sell 15 books each week
Let us assume each week be x
Now the equations are
Beth 250 - 20x
Martin 80 + 15 x
Now the inequality would be
250 - 20 < 80 + 15x
What is the sum of the interior angles of the figure shown
Answer:
C
Step-by-step explanation:
The sum of the interior angles of a square = 360° ( 4 right angles )
The sum of the interior angles of a triangle = 180°
Then sum of interior angles of the figure is
sum = 180° + 180° + 360° = 720° → C

Zahra is a waitress at a restaurant. Each day she works, Zahra will make a guaranteed
wage of $25, however the additional amount that Zahra earns from tips depends on
the number of tables she waits on that day. From past experience, Zahra noticed that
she will get about $14 in tips for each table she waits on. How much would Zahra
expect to earn in a day on which she waits on 10 tables? How much would Zahra
expect to make in a day when waiting on t tables?
Answer:
1. $165
Step-by-step explanation:
Zahra will expect to earn 14 *t +25 in a day on which she waits on "t" tables.
What is Linear function?A linear function in mathematics is one that has either one or two variables and no exponents. It is a function with a straight line as its graph.
Given, Zahra is a waitress at a restaurant. Each day she works, Zahra will make a guaranteed wage of $25,
Let "t" be the tables Zahra is waitressing.
Since, she will get about $14 in tips for each table she waits on.
Total additional tip = t * 14
guaranteed wage = 25$
So, Total Zahra will earn for waitressing on "t" tables = 14 *t +25
For t = 10 tables
Zahra will earn for waitressing on 10 tables = 14 * 10 +25
Zahra will earn for waitressing on 10 tables = 165
Therefore, Zahra will expect to earn $165 in a day on which she waits on 10 tables.

the graphics in a new game program called Zinger they released six months ago. The
company randomly polled 1000 of the 50,000 people who had purchased the program.
Here is part of the results of the poll:
Zinger Program Graphics Percent
Satisfied with Graphics 42%
Not Satisfied with Graphics
No Opinion 13%
a. What percent of the 1000 game users surveyed were not satisfied with the graphics
of Zinger? (2 points)
b. Based on the survey findings, how many of the current 50,000 game users would the
company expect to not be satisfied with the graphics or to have no opinion? (3
points)
c. Based on the survey findings, the software manufacturer has decided to create a new
version of the game program with improved graphics. Why did they make this
decision? (2 points)

Write the equation of the line, in slope-intercept form, with the
following information:
slope: -1
y-intercept: (0, -1)
Answer:
y = -x -1
Step-by-step explanation:
x1= 0, y1= -1
[tex]slope = \frac{x - x1}{y - y1} = \frac{x - 0}{y - ( - 1)} = \frac{x}{y + 1} [/tex]
-1 = x/(y+1)
-1 (y+1) = x
y+1 = -x
y= -x -1
What is 4(2x- 2) + 22
Answer:
8x+14
Step-by-step explanation:
What is the y-coordinate of the solution to the system of equations? 5x-y=25 4x+3y=1
Answer:
The y-coordinate of the solution is thus -5.
Step-by-step explanation:
Rewrite 5x-y=25 4x+3y=1
in a column:
5x-y=25
4x+3y=1
If we want to find the y-coordinate of the solution, we need to eliminate x. Solving the second equation for 4x yieds 4x = 1 - 3y, or
x = (1 - 3y)/4.
If this is inserted into 5x - y = 12, we get:
5(1 - 3y)/4 - y = 25, or (multiplying all terms by 4 to eliminate fractions):
5 - 15y - 4y = 100, or
-19y = 95, which yields y = -5
The y-coordinate of the solution is thus -5.

Answer:
AB = 14
DE =7
Step-by-step explanation:
Remark
AB
Opposite sides of a parallelogram are equal.
AB = CD
AB = 14
DE
According to the diagram AE = 19
AD = 26 which is the same size as BC
DE = 26 - 19 = 7
DE = 7

Answer:
For me i think its 16.67 well im not fully sure
Step-by-step explanation:
SO we have to figure out what gives us 10 and that will be represented as "x"
[tex]\frac{60}{100}[/tex] × x = 10
Multiplying both sides by 100 and dividing both sides by 60,
we have x = 10 × [tex]\frac{100}{60}[/tex] so, x = 16.67
(that's what i believe but i don't know)
Help!!!!! Also shoe the work plz!
Answer:
[tex]h=\frac{15.625}{pi}[/tex]
h ~ 4.974
Step-by-step explanation:
The formula for the volume of a cylinder is;
[tex](pi)(r^{2})(h)=V[/tex]
Where [tex](pi)[/tex] represents the value, [tex]3.1415...[/tex]
[tex](r)[/tex] represents the radius of the given cylinder. In other words, if one were to take a base (the flat side in the case of the cylinder) of the figure. The distance from the center to a point on the outside of the circle is the radius.
[tex](h)[/tex] represents the height of the object. In other words the distance between the two bases of the cylinder.
[tex]V[/tex] represents the volume, in other words, the space that the object takes up.
In this problem, one is given the diameter of the cylinder and the volume. One is asked to find the area.
The diameter of a circle is the distance between two opposite sides of the circle. The diameter will always pass through the center of the circle. To find the radius when given the diameter, one will divide by 2.
To solve this problem, one will substitute in the given information and solve for the height using inverse operations.
[tex](pi)(r^{2})(h)=V\\\\(pi)((\frac{8}{2})^{2})(h)=250\\\\(pi)(16)(h)=250\\\\(pi)(h)=15.625\\\\(h) = \frac{15.625}{pi}\\\\h- approx. 4.974[/tex]

2) Abby spent $152 on Math Team spirit gear. Sweatshirts cost $25 and t-shirts cost $11. If she
bought a total of 10 items, how many of each type of shirt did she buy?
Answer:Abby bought 3 sweat shirts and 7 t shirt
Step-by-step explanation:
Step 1
Let sweat shirt be represented as s
and t shirts be represented as t
such that the total umber of items bought which equals 10 can be written as
s+ t= 10---- equation 1
and total price of the gear with each item costing $25 on sweatshirt $11 on t-shirts be expressed as
25 s+ 11 t = 152---- equation 2
Step 2
s+ t= 10-----equation 1
25s+ 11t= 152----equation 2
By elimination method , multiply equation 1 by 10 and subtract equation 2 from it
25 s+ 25t= 250----- equation 3
-25s + 11t= 152-----equation 2
14t=98
t=98/14= 7
To find s, using equation 1
s+t=10
s= 10-7= 3
Abby bought 3 sweat shirts and 7 t shirt
