D) 498,173.26Jaycie has a VIP membership to a movie theater, so she pays 27 dollars a year and 6.00 for each movie she sees. Claire doesn't have a membership, so she pays 8.25 for each movie she sees. How many movies would they have to see in a year in order to pay the same amount?
Answers
Answer:
12 movies
Step-by-step explanation:
Let the number of movies they see be represented by x
Jaycie has a VIP membership to a movie theater, so she pays 27 dollars a year and 6.00 for each movie she sees.
$27 + $6 × x
= 27 + 6x
Claire doesn't have a membership, so she pays 8.25 for each movie she sees.
= $8.25 × x
= 8.25x
How many movies would they have to see in a year in order to pay the same amount?
Jaycie = Claire
27 + 6x = 8.25x
27 = 8.25x - 6x
27 = 2.25x
x = 27/2.25
x = 12 movies
Therefore, they have to see 12 movies in a year in order to pay the same amount.
Solve the inequality. Graph the solution.
3d−7d+2.8<5.8−27
Answers
Answer:
Step-by-step explanation:
Z>6
The solution to the given inequality would be d > 6, which is shown in the graph with the red line.
Given that,
The inequality to solve,
3d - 7d + 2.8 < 5.8 - 27
Used the concpet of expression for solving by using combining like terms and applying the operations addition, subtraction, etc.
Here, the inequality is,
3d - 7d + 2.8 < 5.8 - 27
Combine like terms,
- 4d + 2.8 < 5.8 - 27
Subtract 2.8 on both sides,
- 4d < 5.8 - 2.8 - 27
- 4d < 3 - 27
- 4d < - 24
Multiply both sides by - 1,
4d > 24
It can be written as,
4d - 24 > 0
4 (d - 6) > 0
d - 6 > 0
Therefore, the solution to an inequality is,
d > 6
And, the graph of solution d > 6 is shown in the attached image.

Please refer to the ATTACHMENT.....I hope it will help.Two points,L and N are 160 m apart. M lies on the straight line joining L and N. An object travels from L to M at an average speed of 10 m/s in 6 seconds and then from M to N at an average speed of 25 m/s. Find the average speed of the object for it's entire journey from L to N.
Answers
Answer:
16m/sStep-by-step explanation:
If the object travels from L to M at an average speed of 10 m/s in 6 seconds, we can get the distance LM using the formula;
Speed = Distance/Time
Distance = Speed * Time
Distance = 10 * 6
Distance = 60m
Hence LM = 60m
Since LN = LM + MN
160 = 60 + MN
MN = 160-60
MN = 100m
If the object moves from M to N at an average speed of 25 m/s througj a distance od 100m, the time taken will be expressed as;
Time = distance/speed
Time = 100/25
Time = 4secs
Total time taken to move from L to N is 6secs + 4secs = 10secs
The average speed of the object for it's entire journey from L to N will be:
Average speed = Distance LN/10
Average speed for the entire journey = 160/10 = 16m/s
Hence the average speed of the object for it's entire journey from L to N is 16m/s

You are considering buying a 30-year U.S. Treasury bond but are nervous about the effect on bond price if the yield to maturity on the bond increases. The bond has a 3% coupon rate and pays coupons semi-annually. The duration is 19 years. Suppose that interest rates on this bond rise by 0.9%. Calculate the corresponding percentage change in the price of the bond using the approximation method based on bond duration.
Answers
Answer:
The corresponding change in bond price = 17.1%
Step-by-step explanation:
In this question, we are interested in calculating the percentage change in the bond price using the approximation method based on bond duration;
Mathematically;
% change in bond price = Duration * Change in yield
From the question;
Duration = 19 years
Change in yield = 0.9%
Thus;
% change in bond price = 19 * 0.9% = 17.1%

Answer:
The first answer is

the other answer is
"Point E represents the smallest number of all the numbers represented by the points
Step-by-step explanation:
Hope this helps!
The correct statements are third "Point D represents a number less than the number Point C represents", and fifth "Point E represents the smallest number of all the numbers represented by points".
Given information:
The number line shows 6 points A, B, C, D, E, and F.
The sequence of numbers from left to right is E, B, D, C, A, and F.
In the number line, a point or number on the right is bigger than the point or number on the left.
From this, we can conclude that:
Point C is on the left of point F. So, point C is less than point F. The first statement is wrong.All the points are on the different locations on the number line. So, all the points represent different numbers. The second statement is also wrong.Point D is on the left of point C. So, the number represented by point D is less than the number represented by point C. The third statement is correct.Point F is on the rightmost location. So, it is the greatest number. The fourth statement is wrong.Point E is on the leftmost location. So, the number represented by point E is the smallest among the given 6 points. The fifth statement is correct.Therefore, the correct statements are third "Point D represents a number less than the number Point C represents", and fifth "Point E represents the smallest number of all the numbers represented by points".

A marching band wants to line up for their performance. When they line up in threes there are 2 left over. When they line up in fours there are 3 left over. When they line up in fives there are 4 left over. When they line up in sixes there are 5 left over.
Answers
Answer: They are 59 members in the band
Step-by-step explanation:
given data:
when lined up in 3 = 2 left.
when lined up in 4 = 3 left
when they are lined up in 5 = 4 left
when they are lined up in 6 = 5 left
Solution:
From the given data, we know the band number ends with 9, so we start with 9,29,49,59. We test till we arrive at our desired answer.
59/3 = 19 R 2.
59/4 = 14 R 3.
59/5 = 11 R 4.

find the equation of the line which passes through the point (7,2) and is perpendicular to y=5x-2
Answers
Answer:
[tex]\displaystyle y=-\frac{1}{5}x+\frac{17}{5}[/tex]
Step-by-step explanation:
Equation of a line
A line can be represented by an equation of the form
[tex]y=mx+b[/tex]
Where x is the independent variable, m is the slope of the line, b is the y-intercept and y is the dependent variable.
We need to find the equation of the line passing through the point (7,2) and is perpendicular to the line y=5x-2.
Two lines with slopes m1 and m2 are perpendicular if:
[tex]m_1.m_2=-1[/tex]
The given line has a slope m1=5, thus the slope of our required line is:
[tex]\displaystyle m_2=-\frac{1}{m_1}=-\frac{1}{5}[/tex]
The equation of the line now can be expressed as:
[tex]\displaystyle y=-\frac{1}{5}x+b[/tex]
We need to find the value of b, which can be done by using the point (7,2):
[tex]\displaystyle 2=-\frac{1}{5}*7+b[/tex]
Operating:
[tex]\displaystyle 2=-\frac{7}{5}+b[/tex]
Multiplying by 5:
[tex]10=-7+5b[/tex]
Operating:
[tex]10+7=5b[/tex]
Solving for b:
[tex]\displaystyle b=\frac{17}{5}[/tex]
The equation of the line is:
[tex]\boxed{\displaystyle y=-\frac{1}{5}x+\frac{17}{5}}[/tex]
If the area of a square is 32 square feet, estimate the length of each side of the square to the nearest whole number.
Answers
Answer:
the answer is actually 6

The length of each side of the square to the nearest whole number is 6 feet.
Given that, the area of a square is 32 square feet.
We need to estimate the length of each side of the square to the nearest whole number.
What is the area of a square?A square is a closed two-dimensional shape with four equal sides and four equal angles. The four sides of the square form the four angles at the vertices. The sum of the total length of the sides of a square is its perimeter, and the total space occupied by the shape is the area of the square. The formula to find the area of a square =a², where a=side of a square.
Now, a²=32 square feet
⇒a=√32
⇒a=5.65≈6
Therefore, the length of each side of the square to the nearest whole number is 6 feet.

Its an obtuse triangle because one of the angle n is 98 degrees
Answer:
Obtuse Triangle
Step-by-step explanation:
First we have to find the measure of all the angles. We know that the sum of all angles in a triangles is 180 degrees.
So we add 35 and 47 which is 82 degrees.
Then we subtract 82 from 180 which is 98 degrees. Now we know that angle N is 82 degrees.
We can go ahead eliminate answer choices acute equiangular triangle (that only applies if all angles are 60 degrees) and right triangle (must have a right angle which is 90 degrees).
That now leaves us with acute and obtuse triangle. An acute triangle has angles that are less that 90 degrees. So that only leaves us with the answer choice obtuse triangle, because it has an angle of 98 degrees which is an obtuse angle.
So your answer is Obtuse Triangle.
