To which sets do positive integers belong? Select all that apply.
The fewest number of points that must be plotted to have examples of all four sets of numbers is including at least one positive and one negative integer is 2 points
The Numbers are generally classified into 2 main groups - Rational numbers and Irrational numbers.
All the four examples listed here are types of rational numbers only.
Now, positive integers are also called as whole numbers and natural numbers. So, one point is enough to represent whole numbers and natural numbers.
Also, another point will be required to show integers because integers can be positive and negative and could include fractions.
Hence, The fewest number of points we must plot to have examples of all four sets of numbers given are 2 points.
As we know that positive integers are types of rational numbers and positive integers are also natural numbers and whole numbers. Therefore all the options given, are positive integers.
The correct question is What is the fewest number of points you must plot in order to have examples of all four sets of numbers, including at least one positive and one negative integer? Explain.

In rhombus ABCD, AC = 18, and BD = 24, what is the
length of one side of the rhombus?
B
1) 30
2) 42
3) 15
4) 21
Answer:
15
Step-by-step explanation:
Here, given the diagonals of the Rhombus, we want to get the length of one side of the Rhombus
We proceed to use the formula below;
d1 = √(4a^2-d2^2
Where d1 represents the length of one diagonal
a is the side of the Rhombus
d2 is the length of the second diagonal
Thus, mathematically;
d2^2 = 4a^2 - d1^2
4a^2 = d2^2 + d1^2
4a^2 = 18^2 + 24^2
4a^2 = 900
a^2 = 900/4
a^2 = 225
a = √225
a = 15
1. Use the distance formula (FOR COORDINATES) to find the distance between A(-6, 4) and B(5,-3).
Answer: [tex]\sqrt{170}[/tex]
Step-by-step explanation:
Distance formula: a^2+b^2=c^2 where c is the distance between two points
(-6-5)^2 + (4-(-3))^2=c^2
(-(6+5))^2 + (4+3)^2=c^2
(-11)^2 + 7^2=c^2
121 + 49=c^2
c^2=170
c=[tex]\sqrt{170}[/tex] ==> distance between A and B

An airplane descends at a rate of 2,700 feet per minute. once the airplane starts its descent, what will be its change in elevation after 312minutes?
The airplane that descends at a rate of 2,700 feet per minute, after 3 1/2 minutes it will be at 9450 ft
The formula and procedure we will use to solve this problem is:
v= x/t
Where:
x = distancet = timev = velocityInformation about the problem:
x = ?t = 3 1/2 minv = 2,700 ft/minConverting the mixed fraction to a fraction, we get:
3 1/2 =
[(3*2) + 1]/2 =
(6+1) / 2 =
7/2
3 1/2 min is equivalent to 7/2
Applying the velocity and isolating the distance we have:
x= v*t
x = 2700 ft/min * 7/2 min
x = 9450 ft
What is velocity?It is a physical quantity that indicates the displacement of a mobile per unit of time, it is expressed in units of distance per time, for example (miles/h, km/h).

7.) The base of a ten-foot ladder stands six feet from a
house. How many feet up the side of the house does the
ladder reach?
10 ft
waaaaaaa
6 ft
Answer:
11.7 ft (11.661903789691 )
Step-by-step explanation:
Draw a right triangle. Legs are 10 ft and 6 ft, we're trying to find the hypotenuse.
We can use the Pythagorean theorem.
a^2 + b^2 = c^2
c = √a2 + √b2
= √(10)2 + √(6)2
= √100 + √36
= √136
= 11.661903789691

A system of equations is graphed below. What is the solution to the system? Explain how you know
GIVING BRAINIEST
Answer:
(3,4)
Step-by-step explanation:
Find equations of both lines
Line 1: y = 1/3x + 3
Line 2: y = 2x - 2
Set then equal to each other, then solve for x:
1/3x + 3 = 2x - 2
1/3x + 5 = 2x
x + 15 = 6x
15 = 5x
x = 3
Then sub x into one of the equations (doesn't matter which one) and solve for y
y = 2x - 2
y = 2(3) - 2
y = 6 - 2
y = 4
Solution is (3,4)

What is the slope of a line perpendicular to the line whose equation is 12x+2y=-1212x+2y=−12. Fully reduce your answer.
Answer:
In this case the slope of a line perpendicular to the line whose equation is 12x+2y=-12 will be [tex]\frac{1}{6}[/tex]
Step-by-step explanation:
A line has the form:
y = m * x + b
where:
m is the slope of the line. b is Y-intercept. This is the value of y where the line crosses the y-axis.In this case, the line has the form 12*x+2*y=-12
First, you must isolate the variable "y", in order to arrive at the form of the line detailed above:
12*x+2*y=-12
2*y= -12 -12*x
y= (-12 -12*x)÷2
y= (-12)÷2 -(12÷2)*x
y= -6 -6*x
In this case: the slope is -6 and the Y-intercept is -6.
Two lines are perpendicular when they form four equal 90º angles. For two lines to be perpendicular, they must have their slopes inverse and changed sign.
Then, in this case the slope of a line perpendicular to the line whose equation is 12x+2y=-12 will be [tex]\frac{1}{6}[/tex]

Step-by-step explanation:
In triangle ABC, the measure of angle B is 18° more than twice the measure of angle A. The measure of angle C is 42° more than that of angle A. Find the angle measures. A: 30°, 78°, 42° B: 30°, 78°, 72° C: 33°, 84°, 63° D: 26°, 70°, 84°
Answer:
B: 30°, 78°, 72
Step-by-step explanation:
Given a [tex]\triangle ABC[/tex].
Let [tex]\angle A = x^\circ[/tex]
As per question statement, [tex]\angle B[/tex] is 18° more than twice of [tex]\angle A[/tex].
i.e
[tex]\angle B =(2x+18)^\circ[/tex]
[tex]\angle C[/tex] is 42° more than that of [tex]\angle A[/tex]
[tex]\angle C = (x+42)^\circ[/tex]
To find:
The angle measures of the triangle = ?
Solution:
We can use the angle sum property of a triangle here to find the three angles of the triangle.
As per angle sum property, the sum of all the three internal angles is equal to [tex]180^\circ[/tex].
[tex]\angle A + \angle B + \angle C= 180^\circ\\\Rightarrow x+2x+18+x+42=180^\circ\\\Rightarrow 4x+60=180\\\Rightarrow 4x=120\\\Rightarrow x= 30^\circ[/tex]
i.e. [tex]\angle A = 30^\circ[/tex]
[tex]\angle B = 2\times 30 + 18 = 78^\circ[/tex]
[tex]\angle C = 30+42 = 72^\circ[/tex]
Therefore, the correct answer is:
B: 30°, 78°, 72
