The factor 3 does not occur in pair. Thus, ‘3’ is the smallest number by which 8112 should be divided to get a perfect square.
What is the lowest square number?The LCM of 8, 15, and 20 is 120. Prime factors 2, 3, and 5 do not have a pair in this case. To construct a perfect square, 120 must be multiplied by 2 x 3 x 5. As a result, the least square number divisible by 8, 15, and 20 is 3600.

which of the following describes the domain of the piecewise function
Answer:
(c) (-∞, -2) ∪ (-2, 1) ∪ (1, ∞)
Step-by-step explanation:
You want the domain of the given piecewise-defined function.
x < 2For x < 2, the function is ...
[tex]g(x)=\dfrac{x^2+2x}{x^2+x-2}-\dfrac{x(x+2)}{(x-1)(x+2)}=\dfrac{x}{x-1}\quad x\ne\{-2,1\}[/tex]
Both of these exclusions are in the region x < 2, so both must be excluded from the domain.
x ≥ 2The log function is defined for all values x > -2, so there are no exclusions in this region.
The domain is (-∞, -2) ∪ (-2, 1) ∪ (1, ∞).

At store B, they charge $0.09 more for pineapple juice than store A.
What is the equation of a line?The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.
Given that, Brody was comparing the price of pineapple juice at two stores.
Equation to represent the cost of pineapple juice at store A is
y=0.7x
Equation to represent the cost of pineapple juice at store B is
From the table, we have (9, 7.11) and (13, 10.27)
Now, slope m= (10.27-7.11)/(13-9)
= 3.16/4
= 0.79
Substitute m=0.79 and (x, y)=(9, 7.11) in y=mx+c, we get
7.11=0.79(9)+c
7.11=7.11+c
c=0
So, the equation is y=0.79x
Cost of 1 bottle juice at store A is $0.7 and Cost of 1 bottle juice at store B is $0.79
Difference in cost =0.79-0.7=$0.09

The Standard form of y= 4/9x - 3 is 4x - 9y = 27.
What is standard form of an equation?
The general form of a linear equation, commonly referred to as the standard form, is written as Ax + By = C.
Given equation : y= 4/9x - 3
Taking LCM on both sides
we get, 9y = 4x - 27
Since the standard form of a linear equation is Ax + By = C.
So, we can write it as 4x - 9y = 27
where A= 4, B = -9 and C= 27.

A. Base, 8 cm; height, 4 cm
B. Base, 4 cm; height, 4 cm
C. Base, 6 cm; height, 8 cm
D. Base, 12 cm; height, 8 cm
The dimensions of the base would be: base: 12 cm ; height : 8 cm
The correct answer is an option (D)
We know that the formula for the volume of a pyramid is:
V = 1/3 × B × h
where B is the base area of the pyramid
h is the height of the pyramid
The shape of the box is a triangular pyramid.
Each box contains 240 cubic centimeters of confetti.
this means, the volume of the box is V = 240 cubic centimeters
Using above formula of the volume of a pyramid,
V = 1/3 × B × h
here V = 240 cubic centimeters and h = 15 centimeters
240 = 1/3 × B × 15
240 = B × 5
B = 240/5
B = 48 square centimeters
The dimensions of the base must be such that the area of the base would be 48 square centimeters.
Here, a pyramid has triangular base.
Using the formula for the area of triangle,
B = 1/2 × base of triangle × height of triangle
48 = 1/2 × base of triangle × height of triangle
base of triangle × height of triangle = 96
for the dimensions Base, 12 cm; height, 8 cm

The correct option is Option 1 - 3520.
A farmer owns 3520 acres in which three full sections, four half-sections, and two quarter-sections are there.
Three of a farmer's sections were full. Let's say a full section is 640, which is
=3 x 640,
= 1,920.
He had four half portions as well. Divide 640 by two to get 320 (640/2), which is
= 4 X 320
= 1,280.
He had three quarter portions as well. Divide 640 by 4 to create a quarter piece (640/4 = 160)
= 2 X 160
= 320.
Now we have to add all these,
Three full sections = 1920
Four half-sections = 1280
Two quarter-sections = 320
= 1,920 + 1,280 + 320
= 3,520.
Therefore the acres a farmer had is 3520.

Greg would need to visit his parents at least 18 times each year to attain gold status. To calculate this, we need to take the minimum flight miles required for gold status (16200) and subtract 900 miles, the round-trip flight distance to visit his parents.
where the value comes from the calculation of 15300 miles. Then, we divide 15300 miles by 900 miles, the round-trip flight distance to visit his parents, and get the answer of 18. Therefore, Greg needs to visit his parents at least 18 times each year to reach gold status. To be eligible for gold status, one must fly a certain amount of miles within a year.
For the airline company that Greg is using, the minimum flight miles required for gold status is 16200. Since Greg is taking a 900-mile round-trip flight to visit his parents, he needs to make up the difference in order to reach the minimum required flight miles. Thus, he needs to visit his parents at least 18 times each year to ensure that he meets the required flight miles for gold status.

At noon, Gabriella is 550 miles away from the stadium and Ian is 950 miles away from the stadium. Gabriella is driving along the highway at a speed of 25 miles per hour and Ian is driving at speed of 50 miles per hour. Let � G represent Gabriella's distance, in miles, away from the stadium � t hours after noon. Let � I represent Ian's distance, in miles, away from the stadium � t hours after noon. Graph each function and determine the number hours after noon, � , t, when Gabriella and Ian are the same distance from the stadium.
Answer: Gabriella's distance from the stadium is modeled by the function G(t) = 550 - 25t.
Ian's distance from the stadium is modeled by the function I(t) = 950 - 50t.
To find the number of hours after noon when Gabriella and Ian are the same distance from the stadium, we need to set the two equations equal to each other and solve for t:
G(t) = 550 - 25t = I(t) = 950 - 50t
Combining like terms we get:
25t = 400
t = 16
So, 16 hours after noon, Gabriella and Ian will be the same distance away from the stadium.
To graph the functions, we can substitute different values of t into the equations to find the corresponding values of G(t) and I(t). Then we can plot the points on a coordinate plane and connect them to form the graph of the two functions.
It is important to note that we are assuming that both Gabriella and Ian don't make any stops, so the speed is constant through the whole trip and no time is wasted.

A senary numeral system (also known as base-6, heximal, or seximal) has six as its base. It has been adopted independently by a small number of cultures. Like decimal, it is a semiprime, though it is unique as the product of the only two consecutive numbers that are both prime (2 and 3). As six is a superior highly composite number, many of the arguments made in favor of the duodecimal system also apply to senary.

A. (600 – 90) x 6 = s
B. 600 + (90 x 6) = s

Johan is driving 90 kilometers every hour and he has been driving for 6 hours, so the distance covered by him is 90*6 = 540 kilometers.
The distance he is away from his destination is the total distance to the destination minus the distance he has covered so far.

What is the Quadratic Equation?
A quadratic equation is a type of polynomial equation that has the general form of ax^2 + bx + c = 0, where x is the variable, a, b, and c are constants, and a is not equal to zero. The degree of the equation is two, hence the name "quadratic".
x+1/6-y can be rewritten in terms of a,b, and c by using the following equation:
ax + by + c = 0
To get x+1/6-y in the values of a,b, and c we can rewrite the equation as follow:
a = 1, b = -1, c = -1/6
So, x+1/6-y can be written as:
1x - 1y - 1/6 = 0
or
ax + by + c = 0 where a=1, b=-1 and c=-1/6

An electric pole 15 m high is supported by a wire fixing its one end on the ground at some distance from the pole. If the wire joining the top of the pole is inclined to the ground at an angle of 60°, find the length of the wire.
Step-by-step explanation:
Givenlength of the pole : 15 m
angle inclined by the wire to the pole from ground :60 deg
let the length of wire : x
therefore
sin (angle) = opposite/hypothesis
sin 60 = 15/x
√3/2 = 15/x
x= 2*15/√3
x = 30/√3
x = 17.320
the length of the wire is :17 m.
