Answer:
There are two limo companies that charge based on the number of people, x, that they carry. Limo A charges $30 plus $4 per person. Limo B charges $70 plus $2 per person. How many people can ride to make the two companies charge the same amount?
Step-by-step explanation:
The correct situation is the third one, this is because the expression we have is:
[tex]30+4x=70+2x[/tex]
let's take the left side as the charge of the company limo A, and the left side as the charge of limo B.
Since 'x' is the number of people, the left side tells us that limo A charges $4 per person (hence the 4x) and adds an additional $30 (hence the 30 added on the left side).
And the right side tells us that limo B charges $2 per person (hence the 2x) and adds an additional $70 (hence the 70 added on the right side).
And since we have an equal sign this means that the expression represents the number of people that can ride and will pay an equal amount in each company.
This is the situation that the third option describes:
There are two limo companies that charge based on the number of people, x, that they carry. Limo A charges $30 plus $4 per person. Limo B charges $70 plus $2 per person. How many people can ride to make the two companies charge the same amount?

After finishing college, Daniel had interviews with SeaWorld and the Central Park Zoo. The probability of receiving an offer from SeaWorld is 35%. The probability of receiving an offer from the Central Park Zoo is 48%. The probability of Daniel getting an offer from both SeaWorld and the Central Park Zoo is 15%.
Determine the probability of receiving an offer from either SeaWord or Central Park Zoo but not both. ____________
Answer:
[tex]68\%[/tex]
Step-by-step explanation:
Let A be the event that Daniel receives call from SeaWorld.
Probability of event A, P(A) = [tex]35\%[/tex]
Let B be the event that Daniel receives call from Central Park Zoo.
Probability of event B, P(B) = [tex]48\%[/tex]
Probability that Daniel receives calls from both SeaWorld and Central Park Zoo:
[tex]P(A \cap B) = 15\%[/tex]
We know that formula:
Probability that Daniel receives call from either SeaWorld or Central Park Zoo but not both:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)\\\Rightarrow P(A \cup B) = 35\% + 48\% - 15\%\\\Rightarrow P(A \cup B) = 68\%[/tex]
Hence, required probability is [tex]68\%[/tex].

A cylinder is 20 inches long and has a diameter of 10 inches. What is the approximate volume of the cylinder?
Answer:
V=π(d/2)^2·h
=π·(10/2)^2 · 20
≈1570.79633in³
this is the correct answer!!!
The approximate volume of the cylinder is 1570.796 inches³.
What is Volume?Volume of a three dimensional shape is the space occupied by the shape.
A cylinder is a geometrical shape has two circular bases which are parallel and they are connected with a curved surface.
Given that,
Height of the cylinder = 20 inches
Diameter of the base = 10 inches
Radius = Diameter / 2 = 10/2 = 5 inches
Volume of the cylinder = π r² h, where r is the radius and h is the height.
Volume = π (5)² (20)
= 500π
= 1570.796 inches³
Hence the volume is approximately 1570.796 inches³.

An insurance policy charges a regular risk premium, , at Years 0,1,2,3,…,9 from today. The policy pays a claim of 2 (i.e. × ) in 15 Years from today. Calculate the value of (to 2 decimal places), assuming an interest rate of 2% per annum.
Answer:
x = 12.29
Step-by-step explanation:
present value of the claim = x² / (1 + 2%)¹⁵ = 0.743x²
present value of the 10 premiums:
x + x/1.02 + x/1.02² + x/1.02³ + x/1.02⁴ + x/1.02⁵ + x/1.02⁶ + x/1.02⁷ + x/1.02⁸ + x/1.02⁹ = x + 0.9504x + 0.9612x + 0.9423x + 0.9238x + 0.9057x + 0.888x + 0.8706x + 0.8535x + 0.8368x = 9.1323x
0.743x² = 9.1323x
x² / x = 9.1323 / 0.743
x = 12.29
Answer
x = 12.29
Step-by-step explanation:
Given that the policy claims x² in 15 years, at 2% = 0.02, the present value of the claim is given as:
x²/(1 + 0.02)^15
= x²(1/1.02)^15
= 0.743x²
The present value of the 10 premiums:
x + x/1.02 + x/1.02² + x/1.02^3 + x/1.02^4 + x/1.02^5 + x/1.02^6 + x/1.02^7 + x/1.02^8 + x/1.02^9
= x + 0.9504x + 0.9612x + 0.9423x + 0.9238x + 0.9057x + 0.888x + 0.8706x + 0.8535x + 0.8368x
= 9.1323x
Now,
0.743x² = 9.1323x
x²/x = 9.1323/0.743
x = 12.29
This is what we are looking for.
A circular swimming pool has a radius of 15ft. There is a path all the way around that pool that is three feet wide. What is the circumference of the outer edge of the path around the pool? Use 3.14 for pie
Answer:
94.2 ft.
Step-by-step explanation:
The equation to find circumference is 2 times pie times radius. We subsitute pie for 3.14. Now the equation is 2(3.14)r. The radius is 15. When we subsitute 15 for r the answer will be 2(3.14)15. Another way to write it is 2 times 3.14 times 15. The answer would be 94.2

Answer:
k = 6
Step-by-step explanation:
Since the figures are similar, we can use ratios to solve
4 28
----- = -------
k 42
Using cross products
4 * 42 = 28k
Divide each side by 28
4*42/28 = 28k/28
6 = k
Answer: k = 6mm
Step-by-step explanation:
The shapes are similar, which means that each side on the triangle is proportionally similar to its corresponding side on the other triangle.
We can use proportions to solve for k:
[tex]\frac{4}{28} = \frac{k}{42}[/tex]
4 and k are proportionally similar and 28 and 42 are proportionally similar.
You can then cross-multiply to get this:
28k = 168
k = 6
The missing side is 6 mm long.

a mini dvd has a radius of 4 centimeters. there is a hole in the middle of the mini dvd with a radius of 1 centimeter. what is the area of one side of the mini dvd
Answer:
Area of one side of mini DVD = 15π or 47.12 cm²
Step-by-step explanation:
The radius of the mini DVD is;r = 4cm.
Area of a circle = πr²
Thus, Area of mini DVD = π × 4² = 16π
Now,we are told the mini DVD has a hole with a radius of 1 cm.
Area of hole = π × 1² = π
To find the area of one side of the mini DVD, we have to subtract the area of the hole from the area of the DVD.
Thus;
Area of one side of mini DVD = 16π - π
= 15π = 47.12 cm²
The class of 2004 holds a reunion each year. In 2005, 87.5% of the 120 graduates attended. In 2006, 90 students went, and in 2007, 75 students went. About how many students do you predict went to the reunion in 2010
Answer:
15 students
Step-by-step explanation:
% of students attended reunion in 2005 = 87.5% of 120
no of students attended reunion in 2005 = 87.5/100 * 120 = 105.
no of students attended reunion in 2006 = 90
no of students attended reunion in 2007 = 75
So , the series for the given year is
105, 90, 75
we can see that this arithmetical progression series
in arithmetical progression series
common difference is = nth term - (n-1)th term
lets takes 3rd and second term as nth term and (n-1)th term
common difference(d) is =75 - 90 = -15
n th term for any arithmetical progression series is given by
nth term = a + (n-1) d
where a is the first term
n is the nth term
d is the common difference
we have to calculate number of students in reunion of of 2010
as reunion began from 2005
2005,2006,2007,2008,2009,2010
so, 2010 is 6th term in series of 105, 90, 75....
6th term = a + (n-1) d
a is 90
6th term = 90+ (6-1)* -15
6th term = 90+ (5)* -15 = 90 - 75 = 15.
Thus, 15 students will attend reunion of 2010

Including Jose, there are eight people in his family.
If order matters, how many ways can he arrange his family members into a row of five seats if Jose must sit in the first seat?
O 35
O 840
O 1,680
0 2,620
Answer:
840
Step-by-step explanation:
Since the order matters, we use the permutations formula to solve this question.
Permutations formula:
The number of possible permutations of x elements from a set of n elements is given by the following formula:
[tex]P_{(n,x)} = \frac{n!}{(n-x)!}[/tex]
In this question:
The first seat is Jose's.
The remaining four are organized among the other 7 members. So
[tex]P_{(7,4)} = \frac{7!}{(7-4)!} = 840[/tex]
So the correct answer is:
840

Use algebraic methods to find as many intersection points of the following curves as possible. Use graphical methods to identify the remaining intersection points.
r = 5 sinθ and r = 5 cosθ
Answer:
Step-by-step explanation:
r =5sin i
r=5 cos i
divide
tan i=1=tan (π/4),tan(π+π/4)
or tan i=tan (π/4),tan(5π/4)
or tan i=tan (2n π+π/4),tan (2nπ+5π/4)
or tan i=tan ((8n+1)π/4),tan((8n+5)π/4)
i=(8n+1)π/4,(8n+5)π/4
where n is an integer.
so we get infinite points of intersection.

Rearrange the equation so u is the independent variable.
4u+8w=-3u+2w
w= __
Rearrange the equation so m is the independent variable.
-2m - 5n = 7m - 3n
Answer:
w = 7u/6
u = 6w/7
m = 2n/-9
n = -9m/2
Step-by-step explanation:
4u + 8w = -3u + 2w
4u - 4u +8w = -3u - 4u +2w
8w -2w = -7u + 2w - 2w
6w = -7u
w = 7u/6
u = 6w/7
AND
-2m - 5n = 7m - 3n
-2m -7m -5n = 7m -7m -3n
-9m -5n +5n = -3n +5n
-9m = 2n
m = 2n/-9
n = -9m/2
