Answer:
Ratio of student who signed up for art club:
1/5
Ratio who signed other club:
4/5
Step-by-step explanation:
First find out ratio who signed up for art club
you have 16 out of 80
find the common factor: 16
16/16 = 1
80/16 = 5
so 1/5
other clubs is the rest so 5/5 - 1/5 = 4/5

Island Bank is advertising a special 1.55% APR for long term CDs. Manny takes out a one-year CD for $40,000. The interest is compounded daily. Find the annual percentage yield for Manny's account to the nearest hundredth of a percent. Fill in the blank 1
Answer: 1.55%
Step-by-step explanation:
p = Principal = $40000
r = Interest rate = 1.55% = 0.0155
n = Number of periods = 365
APY = [1 + (r/n)^n - 1]
= [1 + (0.0155/365)^365 - 1]
= [1 + 0.000042)^365 - 1]
= [1.000042]^365 - 1
= 1.015448 - 1
= 1.55%

An Airplane is ascending at a speed of 400 km/hr along a line making an angle of 60' with the
ground. How fast is the altitude of the plane changing?
Answer:
The altitude is changing at a speed of 200 √3 km/hr
Step-by-step explanation:
Here, we want to know how far the altitude of the plane is changing
we are told that the airplane makes an angle of 60 degrees with the ground
So therefore , the rate of change of its altitude will be ;
sin 60 = x/ 400
x = 400 sin 60
x = 400 * √3/2
x = 200 √3 km/hr
The altitude is increasing at a rate of 346.61 km/hr.
The diagram below denotes the given scenario.
Then from the diagram we have,
[tex]sin60^{\circ}=\frac{y}{z}\\\frac{\sqrt{3}}{2} =\frac{y}{z}\\ y=\sqrt{3}\\z=2[/tex]
Then,
[tex]sin\theta =\frac{y}{z}\\cos\theta \frac{d\theta}{dt}\\=\frac{z\frac{dy}{dt}-y\frac{dz}{dt}}{z^2} \\\frac{dy}{dt}=\frac{z^2cos\theta\frac{d\theta}{dt+y\frac{dz}{dt}}}{z}\\\frac{dy}{dt} =\frac{2^2(cos60^{\circ})+\sqrt{3}(400)}{2}\\ \frac{dy}{dt}=346.41 km/hr[/tex]

Find a cubic function f(x) = ax3 + bx2 + cx + d that has a local maximum value of 3 at x = −3 and a local minimum value of 0 at x = 1.
Answer:
The cubic function is f(x) = (27/32)·x - 3/32·x³ - -9/32·x² - 9/32
Step-by-step explanation:
The given function is f(x) = a·x³ + b·x² + c·x + d
By differentiation, we have;
3·a·x² + 2·b·x + c = 0
3·a·(-3)² + 2·b·(-3) + c = 0
3·a·9 - 6·b + c = 0
27·a - 6·b + c = 0
3·a·(1)² + 2·b·(1) + c = 0
3·a + 2·b + c = 0
a·(-3)³ + b·(-3)² + c·(-3) + d = -3
-27·a + 9·b - 3·c + d = -3...(1)
a + b + c + d = 0...(2)
Subtracting equation (1) from equation (2) gives;
28·a - 8·b + 4·c = 3
Therefore, we have;
27·a - 6·b + c = 0
3·a + 2·b + c = 0
28·a - 8·b + 4·c = 0
Solving the system of equations using an Wolfram Alpha gives;
a = -3/32, b = -9/32, c = 27/32 from which we have;
a + b + c + d = 0 3 × (-3/32) + 2 × (-9/32) + (27/32) + d = 0
d = 0 - (0 3 × (-3/32) + 2 × (-9/32) + (27/32)) = -9/32
The cubic function is therefore f(x) = (-3/32)·x³ + (-9/32)·x² + (27/32)·x + (-9/32).

You subtract the money she has left over and then divide that number by the amount of books that were bought
66 Divided by 6 = 11
One hundred people are recruited for an experimental study to determine whether
exercising 30 minutes before lunch or 30 minutes after lunch will help improve heart health more. They will be split into two groups that do not necessarily need to be the same size. One group will exercise and then eat, and the other group will do the same exercises after eating instead. After a month, each person's heart health improvement will be assessed by the same doctor, and the groups will be compared. The participants' names will be on a numbered list based on the order in which they agreed to join the experiment.

Flip a coin for each person on the list. If the coin comes up heads, they will be put in the group that exercises before lunch. If the coin comes up tails, they will be put in the group that exercises after
lunch
Participants are divided based on their birth month. Those born in January through June will exercise before lunch, and those born in July through December will exercise after lunch.
Participants choose which group to join based on convenience for their work or school schedule.

A meat packer has 180 kilograms of ground meat. He will divide it equally into 50 packages. How much will each package weigh?
Answer:
3.6 kg
Step-by-step explanation:
A meat packer has 180 kilograms of ground meat. He will divide it equally into 50 packages. How much will each package weigh??
Since he is dividing equally, we have:
50 packages = 180 kg
1 package = x kg
Cross Multiply
x kg × 50 packages= 180kg × 1 packages
x kg = 180 kg × 1/50 packages
x kg = 3.6 kg
Hence, 1 package would weigh 3.6 kg(kilograms)

Escribe dos numeros cuyo maximo comun divisor sea 210 y que esten entre 10000 y 11000
Let [tex]p[/tex] and [tex]q[/tex] be two numbers, such that
[tex]10000 < 210p < 11000, \quad 10000 < 210q < 11000[/tex]
If [tex]p[/tex] and [tex]q[/tex] have no common factors, the greatest common factor between [tex]210p[/tex] and [tex]210 q[/tex] is obviously 210.
If we divide the inequalities above by 210, we see that

And rounding to the nearest integer, we deduce that [tex]p[/tex] and [tex]q[/tex] must be between 48 and 52.
We may pick [tex]p=49[/tex] and [tex]q=50[/tex], because they have no common factors. So, our numbers would be

At the end of 2006, the population of Riverside was 400 people. The population for this small town can be modeled by the equation below, where t represents the number of years since the end of 2006 and P represents the number of people. Based on this model, approximately what was the increase in the population of Riverside at the end of 2009 compared to the end of 2006?
The correct format of the question is
At the end of 2006, the population of Riverside was 400 people. The population for this small town can be modeled by the equation below, where t represents the number of years since the end of 2006 and P represents the number of people. [tex]P = 400 ( 1.2 )^ t[/tex] Based on this model, approximately what was the increase in the population of Riverside at the end of 2009 compared to the end of 2006?
(A) 291
(B) 691
(C) 1040
(D) 1440
Answer:
The increase in the population at the end of 2009 is 291 people
Step-by-step explanation:
We are given the equation as [tex]P = 400 ( 1.2 )^ t[/tex]
where
P = No of People
t= No of Years
it is given that in the year 2006 the population is 400
this will only happen when we take t= 0
so for
Year value of t
2006- t = 0
2007- t = 1
2008- t = 2
2009 t = 3
No of people in 2009 will be
[tex]P = 400(1.2)^3[/tex]
= 400*1.728
P = 691.2
Since the equation represents no of people so it can't be in decimals, Therefore the population will be 691
Increase = P(2009) - P(2006)
= 691 - 400
= 291
The increase in the population at the end of 2009 is 291 people.

Name the property that the statement illustrates.
Answer:
Transitive property of segment congruence
Step-by-step explanation:
The reflexive, symmetric, and transitive properties are the criterion for an equivalence relation. In terms of congruence,
The reflexive property states that [tex]\overline{XY} \cong \overline{XY}[/tex] (a segment is congruent to itself)The symmetric property states that if [tex]\overline{AB} \cong \overline{CD}[/tex], then [tex]\overline{CD} \cong \overline{AB}[/tex] (this is essentially commutativity)The transitive property states that if [tex]\overline{AB} \cong \overline{CD}[/tex] and [tex]\ovelrine{CD} \cong \overline{EF}[/tex], then [tex]\overline{AB} \cong \overline{EF}[/tex].In terms of general equivalence relations,
The reflective property states that [tex]a = a[/tex].The symmetric property states that if [tex]a=b[/tex], then [tex]b=a[/tex].The transitive property states that if [tex]a=b[/tex] and [tex]b=c[/tex], then [tex]a=c[/tex].That's the transitive property.
The fact that congruence is transitive means exactly what you have written: if A is congruent to B and B is congruent to C, then you can "bridge" from A to C.
What is the inverse of the function f(x) = 1/4x - 12?
Oh(x) = 48x - 4
Oh(x) = 48x + 4
O h(x) = 4x - 48
O h(x) = 4x + 48
Happy Holidays! :)
[tex]\large\boxed{h(x) = 4x + 48}[/tex]
[tex]f(x) = \frac{1}{4}x - 12[/tex]
Find the inverse. Begin by swapping the x and y (f(x)) variables:
[tex]x= \frac{1}{4}y - 12[/tex]
Begin isolating for y. Add 12 to both sides:
[tex]x + 12 = \frac{1}{4}y[/tex]
Multiply both sides by 4:
[tex]4(x + 12) = \frac{1}{4}y * 4[/tex]
[tex]4x + 48 = y[/tex]
Therefore:
[tex]h(x) = 4x + 48[/tex]

From the given information we found out that age of Mia is 16 years.
What is a linear equation?A linear equation is an algebraic equation of degree one. In general, the variable or the variables(in the case of a linear equation in two variables) the variables are x and y.
Given, Mia discovered that if she takes half her age and adds 3,
Assuming Mia's age to be x years.
∴ (1/2)x + 3...(i)
It produces the same result as taking one-fourth of her age and adding 7,
∴ (1/4)x + 7...(ii)
So, (1/2)x + 3 = (1/4)x + 7.
(1/2)x - (1/4)x = 7 - 3.
(1/4)x = 4.
x = 4×4/1.
x = 16.
So, Age of Mia is 16 years.
