The number of ways that they can share these fruits if each person must have at least 1 fruit will be 12 ways.
How to illustrate the information?From the information, 6 apples and 5 oranges are shared among 3 people and the apples are indistinguiable, oranges are also indistinguiable.
Therefore, the number of ways that they can share these fruits if each person must have at least 1 fruit will be:
= (6 - 3)! × (5 - 3)!
= 3! × 2!
= 3 × 2 × 2
= 12
Therefore, the number of ways that they can share these fruits if each person must have at least 1 fruit will be 12 ways.

Write an equation for line L in point-slope form.
(Simplify your answer. Use integers or fractions
for any numbers in the equation.)
Step-by-step explanation:
the line is perpendicular to
y = 2x.
and it goes through the point (1, 2).
the point-slope form looks like
y - y1 = a(x - x1)
"a"being the slope, and (x1, y1) being a point on the line.
the slope-intercept form is
y = ax + b
"a" is again the slope, "b" is the y-intercept (the y value when x = 0).
as you can see, we need the slope of the new line in both cases.
then we will start with the point-slope form, and transform it into the slope-intercept form.
the slope of a line is generally the ratio (y coordinate change / x coordinate change) when going from one point on the line to another.
it is always the factor of x.
we can see it is 2 for the original line. that means 2/1.
a perpendicular slope is turning the x and y values upside down, and is flipping the sign.
so, in our case it is
-1/2
so, starting with the new slope and the point to create the point-slope form :
y - 2 = -1/2 × (x - 1)
and from there we transform into the slope-intercept form :
2y - 4 = -x + 1
2y = -x + 5
y = (-x + 5)/2 = -1/2 x + 5/2 = -1/2 × (x - 5)
all of the expressions in the last line are valid forms to write it.

Point J is on line segment I K ‾ IK . Given J K = 10 JK=10 and I K = 19 , IK=19, determine the length I J ‾ . IJ
The length of the line segment IJ is 9.
What is the length of a line segment?
In this question we find that the line segments IJ and JK are collinear, that is, part of one same line. By Euclidean geometry and algebra, we construct the following formula:
IK = IJ + JK
IJ = IK - JK
If we know that IK = 19 and JK = 10, then the length of the missing line segment is:
IJ = 19 - 10
IJ = 9
The length of the line segment IJ is 9.

c. Use the answer from part a to find the half-life of the element.
a. The exponential equation in the form y=yoekt is
(Round to three decimal places as needed.)
The answers are given below:-
a) The exponential function is: [tex]y(t) = 500e^{-0.0117593}[/tex]
b) The rule is: [tex]y(t) = y(0)(\dfrac{358}{500})^{\frac{t}{8}[/tex]
c) The half-life of the element is of 16.599 days.
What is the exponential function?The mathematical expression [tex]f(x) = e^x[/tex] denotes the exponential function. The phrase typically refers to the positive-valued function of a real variable, unless otherwise specified.
Following t days, the substance's amount's exponential function is given by:
[tex]y(t) = y(0)e^{-kt}[/tex]
For this problem, we have that:
y(0) = 500, y(8) = 358.
Hence we can solve for k as follows:
[tex]y(t) = y(0)e^{-kt}[/tex]
[tex]358=500e^{-8k}[/tex]
[tex]e^{-8k}=\dfrac{358}{500}[/tex]
[tex]lne^-8k}=ln0.716[/tex]
-8k = ln(0.716)
k = -ln(0.716)/8
k = 0.041759389.
Hence:
[tex]y(t) = 500e^{-0.0117593}[/tex]
For item b, 358/500 of the material is what is left over after each 8-day period, therefore f(t) = t/8, and the rule is as follows:
[tex]y(t) = y(0)(\dfrac{358}{500})^{\frac{t}{8}[/tex]
For item c, using the rule from item a, we have to find t for which y(t) = 0.5y(0), hence:
[tex]y(t) = y(0)e^{-0.0117593}[/tex]
[tex]0.5y(0)=y(0)e^{-0.0117593[/tex]
[tex]e^{-0.0117593}=0.5[/tex]
[tex]lne^{-0.0117593}=ln0.5[/tex]
-0.041759389t = ln(0.5)
t = -ln(0.5)/0.041759389
t = 16.599.
The half-life of the element is of 16.599 days.

Cheryl's softball batting average is 0.340 and Karen's is 0.304. Karen says they have the same average. What error did she make
The mistake is that in both numbers 0.304 and 0.340, 4 is in the tenth position following the point.
What is place value system?The combination of numerical variables and operations expressed by the addition, subtraction, multiplication, and division signs is known as a mathematical expression. A place-value system gives a number's specific location within a series a value.
Karin's softball batting average is 0.304, whereas Cheryl's is 0.340. They have the same average, according to Karin.
Because the numbers 0.340 and 4 are in the tenth position, as opposed to 0.304 and 4, the values are different from one another.

Two towns are 52 km apart. Buses travelling
between the two towns leave at the same
time but travel in opposite directions. The
bus from town A is travelling 80 km/h and
the bus from town B is travelling 70 km/h.
How long after they leave will they pass each
other? (Reminder: there are 60 minutes in an
hour!)
Step-by-step explanation:
x = number of km bus from A drives until they meet.
y = number of km bus from B drives until they meet.
x/80 is the time for the bus from A to reach the meeting point.
x/70 is the time for the bus from B to reach the meeting point.
both times must be equal, as they start at the same time.
so,
x/80 = y/70
but then we also know that together they have traveled the full 52 km to meet.
so,
x + y = 52
x = 52 - y
with that we go into the first equation :
(52 - y)/80 = y/70
(52 - y)/8 = y/7
7×(52 - y)/8 = y
7×(52 - y) = 8y
364 - 7y = 8y
364 = 15y
y = 364/15 km = 24.26666666... km
x = 52 - y = (780-364)/15 = 416/15 = 27.73333333... km
they will meet after (using bus from B)
364/15 / 70/1 = 364/1050 hours
= 182/525 hours =
= 60×182/525 = 10920/525 minutes =
= 728/35 = 104/5 = 20.8 minutes =
= 20 minutes 60×8/10 seconds =
= 20 minutes 48 seconds
control (using bus from A) :
416/15 / 80/1 = 416/1200 hours =
= 26/75 hours =
= 60×26/75 = 1560/75 minutes =
= 104/5 = 20.8 minutes

An open-top water tank is in the shape of a cuboid. The tank has a square base of side length s m, and has a volume of 216 m^3. Find expressions, in terms of s, for:
a) the height of the tank.
b) the surface area of the tank
Given that the surface area of the open-top water tank is minimised:
c) find the value of s.
(looking for clear workouts and reasoning / explanation behind every step taken no matter how basic it may be)
Answers:
a) h = 216/s^2
b) A = s^2 + 864
c) s = cube root of 432
The height of the tank is h = 216/s^2, the surface area is s^2 + 864/s and the value of s is ∛432
How to determine the height of the tank?The given parameters are
Volume = 216
Base length = s
Height = h
The base shape is a square.
So, we have
Volume = s^2h
This gives
216 = s^2h
Divide through by s^2
h = 216/s^2
Hence, the height of the tank is h = 216/s^2
The surface area of the tankThis is calculated as
A = s^2 + 4sh
So, we have
A = s^2 + 4 * s * 216/s^2
Evaluate
A = s^2 + 4 * s * 216/s^2
This gives
A = s^2 + 864/s
How to determine the value of s?Here, we have
A = s^2 + 864/s
Differentiate
A' = 2s - 864/s^2
Set to 0
2s - 864/s^2 = 0
Divide through by s
2 - 864/s^3 = 0
So, we have
864/s^3 = 2
This gives
2s^3 = 864
Divide by 2
s^3 = 432
Take the cube root
s = ∛432
Hence, the value of s is ∛432
