Step-by-step explanation:
A class consists of 20 sophomores and 15 freshmen. The club needs to choose four different members to be president, vice president, secretary, and treasurer. In how many ways is this possible if sophomores will be chosen as president and treasurer and freshmen as vice president and secretary?
Please explain your answer instead of just providing the answer for the points!
Answer:
There are 79,800 ways in which this is possible.
Step-by-step explanation:
The order in which the students are chosen is important(due to different roles), which means that the permutations formula is used 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:
2 sophomores from a set of 20.
2 freshmen from a set of 15. So
[tex]P_{20,2}*P_{15,2} = \frac{20!}{18!}*\frac{15!}{13!} = 20*19*15*14 = 79800[/tex]
There are 79,800 ways in which this is possible.

maybe B . . . it is the closest
Step-by-step explanation:
There are 180/π degrees in a radian.
__
11π/8 radians = (11π/8)(180°/π) = (11/8)(180°) = 247.5°

Identify the constant term in the expression:
2x + y + 3z + 5
Answer: 5
Step-by-step explanation:
Constants are numbers without a variable
Answer:
5 is constant term
Step-by-step explanation:
A constant term is a term in an algebraic expression that has a value that is constant or cannot change. It does not contain any modifiable variables. Hope it is helpful....For a science project, Levan launches a rocket from ground level directly upward at 29.4 meters per second. As the rocket flies, its height in meters above the ground can be modeled as a function of time
by the equation s(t) = -4.96 +29.4t, where t represents the number of seconds after launch.
Use the point tool to plot the points on the grid that best represent
• when Levan launches the rocket
• the rocket at its highest point and
. when the rocket lands on the ground

Find the value of X.
9514 1404 393
Answer:
x = 6
Step-by-step explanation:
Angles AFB and CFE are vertical angles, so have the same measure. That means arc AB has the same measure of arc CE. The latter arc is 27° more than arc DE, which is 90°. So, we have ...
arc AB = arc CE
21x -9 = 90 +27
21x = 126 . . . . . . add 9, collect terms
x = 6 . . . . . . . divide by 21
Convert. 2/3and 4/6 into like fraction
Answer:
Answer given below
Step-by-step explanation:
When we calculate the LCM, you get it as 6.
So both the fractions should have a denominator 6.
For that, in 2/3 we should multiply both numerator and denominator with 2 so that denominator becomes 6.
When we convert to like fraction, 2/3 becomes 4/6.
Now both the fractions have common denominator

Long before music was recorded digitally, people listened to music played on phonographs.
An antiques dealer models the value of a vintage phonograph using the function V(t) =
0.04t? - 3t + 395, where V(t) is the value in dollars and t is the number of years since 1925.
The phonograph's value dropped as newer versions were introduced but then rose as it
became an antique.
In what year did the phonograph's value equal the value it had in the year 1925? What was
that value?
Round your answers to the nearest whole number.
The phonograph was worth $
value again in the year
in the year 1925. The phonograph had that same

Lorenzo has 4 packages of granola bars.
Each package has 10 bars.
He eats one bar from each package.
Which equation shows how Lorenzo can correctly find the total number of granola bars remaining?
4 × 10 – 4 = 36 granola bars
4 × 10 × 1 = 40 granola bars
4 × 10 + 4 = 44 granola bars
4 + 10 – 4 = 10 granola bars
Answer:
A. 4 x 10 - 4 = 36
Step-by-step explanation:
Ten bars are in a package and there are 4 packages
1 bar is eaten from the 4 packages
40 - (1 x 4) =
40 - 4 =
36

Find the midpoint of the segment below and enter its coordinates as an
ordered pair. If necessary, express coordinates as fractions, using the slash
mark ( / ) for the fraction bar.
(4,0) (12,0)
Given:
The end points of a line segment are (4,0) and (12,0).
To find:
The midpoint of the line segment.
Solution:
Midpoint formula:
[tex]Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)[/tex]
The end points of a line segment are (4,0) and (12,0). So, the midpoint of the line segment is:
[tex]Midpoint=\left(\dfrac{4+12}{2},\dfrac{0+0}{2}\right)[/tex]
[tex]Midpoint=\left(\dfrac{16}{2},\dfrac{0}{2}\right)[/tex]
[tex]Midpoint=\left(8,0\right)[/tex]
Therefore, the midpoint of the given line segment is (8,0).

Answer:
288
Step-by-step explanation:
To solve, we need to find the area of the four triangle sides and add that to the square base's area.
Area of triangle sides: base * height * 0.5
Area of square base: base * height
Substitute the values
8 * 14 * 0.5 = 56
There are four of these sides, so the area of all the triangles is 224.
The square base is 8 * 8, or 64
Add these two values together.
64 + 224 = 288
Thus, the answer is 288

Two years ago, there were 30 foxes in a forest. this year, there are 40 foxes in the forest. what is the annual percent growth for the foxes?
9514 1404 393
Answer:
about 15.5%
Step-by-step explanation:
The number of foxes in the forest can be modeled by the exponential equation ...
f = a·b^t
where a is the initial number, and b is the growth factor per year for t years. The growth factor is 1 more than the growth rate (r), so we can put numbers in this formula to get ...
40 = 30·(1 +r)^2
4/3 = (1 +r)^2 . . . . . . divide by 30
1 +r = √(4/3) . . . . . . take the square root
r = √(4/3) -1 ≈ 0.1547 ≈ 15.5%
The annual percentage growth in the fox population is about 15.5%.

Answer:
A. 15.250
Step-by-step explanation:
The applicable trig function is the cosine function:
Cos = Adjacent/Hypotenuse
cos(57°) = y/28
y = 28×cos(57°) ≈ 15.24989
y ≈ 15.250 . . . . matches choice A
_____
Additional comment
From your knowledge of "special" triangles, you know that y would be 14 if the angle were 60°. Of course, the length must be shorter than 28, so answer choices B and C are immediately eliminated. The fact that the length is closer to half of 28 than it is to 28 makes choice A look like a pretty good guess.
