List the first three common multiples of 31, 18, and 20. (I know the answer, just not how to get the answer)
The 3 common multiples of 31, 18, and 20 are 5580, 11160 and 16740.
Here, we have three numbers- 31, 18, and 20
To find 3 common multiples of these numbers, we first find the least common multiple or LCM of these 3 numbers.
31 is a prime number, hence it can be written as- 31 × 1
18 can be written as- 3 × 3 × 2
20 can be written as- 5 × 2 × 2
Thus, the LCM of 31, 18 and 20 will be-
3 × 3 × 5 × 2 × 2× 31 × 1
= 5580
Thus, we found the least common multiple of 31, 18 and 20.
Now, the other 2 multiples will be multiples of the LCM itself.
The other two numbers can be-
5580 × 2 = 11,160
5580 × 3 = 16,740
Thus, the 3 common multiples of 31, 18, and 20 are 5580, 11160 and 16740.

Trigonometry is one of the most important branches in mathematics that finds huge application in diverse fields. The branch called “Trigonometry” basically deals with the study of the relationship between the sides and angles of the right-angle triangle. Hence, it helps to find the missing or unknown angles or sides of a right triangle using trigonometric formulas, functions, or trigonometric identities. In trigonometry, the angles can be either measured in degrees or radians.
In this article, let us discuss the six important trigonometric functions, ratios, trigonometry tables, formulas, and identities that help to find the missing angles or sides of a right triangle.
Trigonometry is one of the important branches in the history of mathematics that deals with the study of the relationship between the sides and angles of a right-angled triangle.
Solution :
Trigonometry
Length of shadow= 120-105
Length if shadow= 15 feet
height= x
X/15= 32/120
X= 15*32/120
x= 15* 16/60
x= 15*8/30
x= 15*4/15

Need help please
[tex]f^{-1}[/tex](f(6.022)) is 6.022 and [tex]f^{-1}[/tex](-10) + f(6) is -4
The general evaluation of function is
[tex]f^{-1}[/tex](f(x)) = x
Here we have to find [tex]f^{-1}[/tex](f(6.022))
Therefore [tex]f^{-1}[/tex](f(6.022)) = 6.022
Now we have to find the value of [tex]f^{-1}[/tex](-10) + f(6)
Form the table of values, we have
[tex]f^{-1}[/tex](-10) = -6 and f(6) = -10
So we have
[tex]f^{-1}[/tex](-10) + f(6) = 6 + (-10)

A certain medicine is given in amount proportional to a patient body weight.suppose a patient weighing 195 pounds requires 279 milligrams of medicine .what is the amount if medicine required by a patient weighing 130 pounds
The amount of medicine required by a patient weighing 130 pounds is 186 milligrams of medicine.
What is a ratio?A ratio is a comparison of two or more numbers that indicates their sizes and amount in relation to each other.
We have,
Patients weighing 195 pounds require 279 milligrams of medicine.
We can write this in ratio as:
= 279 / 195
Now,
We need to have both patients in proportion.
Proportion means their ratios must be equal.
Let the amount of medicine required for the second patient be M.
We have,
279 / 195 = M / 130
We will find M.
(279 x 130) / 195 = M
M = 186

what is the value of in the system of equations?
Here we have the system of equations:
3x+y+2z= -10
x+5y+2z= -12
-2x+3y = -1
And we want to find the value of x.
Using the third equation we can write y in terms of x:
y = (-1 + 2x)/3
Now we can replace that in the other two equations:
3x + (-1 + 2x)/3 + 2z= -10
x + 5*(-1 + 2x)/3 + 2z= -12
We can simplify thes two to get:
(3 + 2/3)*x + 2z = -10 + 1/3 = -29/3
(1 + 2/3)*x + 2z = -12 +5/3 = -31/3
Now if we subtract these two equations we will get:
(3 + 2/3)*x - (1 + 2/3)*x = -29/3 + 31/3 = 2/3
2x = 2/3
x = (2/3)/2 = 1/3

OA. x = -9
B. X=-6

OD. y=-4
The equation of the line will be x = -6, that is, option B.
Here, we are given that a line passes through point (-6,-9) and perpendicular to y = 1/4
If two line are perpendicular to each other, the product of their slopes is equal to -1.
Here, the slope of y = 1/4 will be 0 as y is a constant value and not changing.
Let the slope of the given equation be m
them m × 0 = -1
m = -1/0
Thus, the slope is not defined, this means that the line will be parallel to x axis of the form x = k.
Now, we know that the line passes through point (-6,-9). This means that if y = -9, x will be -6. But we know that x will take only one value for all values of y.

A rectangle has a perimeter of 37 cm more than the width. If the width and the length are consecutive odd integers, with the width being the smallest of the
two, find the width and length of the rectangle.
width=
cm, length=
cm
The width and length of the rectangle are 11 and 13 cm respectively
What are perimeters?The perimeter of a shape is the sum of the side lengths of the shape
For all regular quadrilaterals, you add up the side lengths to determine the perimeter
How to determine the width and length of the rectangle?The given parameters about the rectangle are
Perimeter = 37 + Width
Length = Width + 2 i.e. consecutive odd integers, and width is smaller
Rewrite the above equations as
p = 37 + w
l = w + 2
The perimeter of a rectangle is
p = 2 x (l + w)
Substitute p = 37 + w in the above equation
So, we have
2 x (l + w)= 37 + w
Substitute l = w+ 2 in the above equation
So, we have
2 x (w + 2 + w)= 37 + w
Evaluate the like terms in the above equation
So, we have
2 x (2w + 2)= 37 + w
Open the bracket in the above equation
So, we have
4w + 4= 37 + w
Evaluate the like terms in the above equation
So, we have
3w = 33
Divide both sides of the above equation by 3
So, we have
w = 11
Recall that
l = w + 2
So, we have
l = 11 + 2
Evaluate
l = 13
Hence, the width and length of the rectangle are 11 and 13 cm respectively

The Wind Up Corp computed their monthly expense equation as E=3.2q+56,000. Its products will be sold to retailers at a wholesale price of 3.56 each. What is the revenue equation? r=?
The revenue equation of the item is r = 3.56q
How to determine what is the revenue equation?The given parameters are:
Expense equation, E = 3.2q + 56000
Selling price = 3.56 per item
This means that the selling price equation is
S = Selling price per item * Number of items
So, we have
S = 3.56 * q
This gives
S = 3.56q
The total selling price of the item is the same as the revenue equation
So, we have
r = 3.56q
Note that the revenue equation is also a linear equation
Where linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient
Hence, the revenue equation of the item is r = 3.56q

4-3 = 1-2-(-3) = 1101-100 = 1So, given question, we can write:
For a consecutive integers, the number either increases by 1 or decreases.
First we take option 1:
12,22,32
Find out difference,
22-12=10 , 32-22=10
The difference is '10'
Hence it is not consecutive integer.
We take option 2:
100,99,98
Find out difference,
100-99=1 , 99-98=1
The difference is '1'
Hence it is consecutive integer.
We take option 3:
-11,-10,-9
Find out difference,
=-10-(-11) , =-9-(-10)
=11-10=1 , =-9+10=1
The difference is '1'
Hence it is consecutive integer.
We take option 4:
10,11,12
Find out difference,
11-10=1 , 12-11=1
