Name the set(s) of numbers to which -1/3 belongs
Answer:
Rational numbersReal numbersStep-by-step explanation:
The number -1/3 belongs to the set of rational numbers.
A number -1/3 is given in the question.
We have to find out that this number belongs to which set of numbers.
What is a rational number ?
A rational number is one which can be expressed as fraction p/q of two integers where p is a numerator and q is a non-zero denominator i.e., q ≠ 0.
Let's check -1/3 belongs to which set,
We know that ,
Natural numbers are the counting numbers , so -1/3 can't be a natural number.
Also ;
-1/3 can't be a irrational number because as this number is a finite number.
Let's check if it is a rational number ;
We know that rational number can be expressed in form of p/q.
Hence ;
[tex]\frac{p}{q}[/tex] = [tex]\frac{-1}{3}[/tex] , where ; p = -1 and q = 3 i.e., q ≠0
Thus , the number -1/3 belongs to the set of rational numbers.

Step-by-step explanation:
Two lawn care companies are competing for a landscaping contract. Company A charges a $250 monthly consulting fee plus $10 per square foot, whereas Company B charges a $90 landscaping fee plus $12 per square foot. When will the two companies charge the same amount?
Let x be the no.of square feet for landscaping
Company A
Monthly consulting fee = $250
Cost of landscaping of 1 sq.feet = $10
Cost of landscaping of x sq.feet = $10x
So, Total charge by company A = 250+10x ---1
Company B
Monthly consulting fee = $90
Cost of landscaping of 1 sq.feet = $12
Cost of landscaping of x sq.feet = $12x
So, Total charge by company B = 90+12x ---2
Now we are supposed to find how many square feet of landscaping will the two companies charge the same amount
So, Equate 1 and 2
[tex]250+10x=90+12x\\160=2x\\80=x[/tex]
So, the two companies charge the same amount for 80 sq.feet
Total charge by company A for 80 sq.feet = 250+10(80)= $1050
Total charge by company B for 80 sq.feet = 90+12(90)=$1170

Write the equation of the line that is parallel to the line y=−74x−2
y
=

x
−
2
through the point (4,-2).
Answer:
The answer is
y = 74x - 298Step-by-step explanation:
Equation of a line is y = mx + c
where
m is the slope
c is the y intercept
To find the equation of the line parallel to the equation above we must first find the slope of the above equation
y = - 74x - 2
Comparing with the above formula
Slope = - 74
Since the lines are parallel their slope are also the same
Slope of parallel line = - 74
Equation of the line using point (4 , -2) and slope - 74 is
y + 2 = 74( x - 4)
y + 2 = 74x - 296
y = 74x - 296 - 2
We have the final answer as
y = 74x - 298Hope this helps you

Answer: 13.5π≈42.41
Step-by-step explanation:
Basically it is asking for the circumference of this cylinder.
#1 Find the circumference of the circle base
Formula to use: 2πr
2πr=2π(1.5)=3π
---------------------------
#2 Find the area of the circle base
Formula to use: πr²
πr²=π(1.5)²=2.25π
--------------------------
#3 Find the area of body of the cylinder
Formula to use: lw
300cm=3m
l (length)= 3π (since the body of the cylinder the basing on the circumference of the circle base)
w (width)= 3
lw=3π×3m=9π
----------------------------
#4 Add all of them together
There are 2 base and one body
2.25π×2+9π=13.5π

The table represents the observed number of leaves y on x branches of a tree. Calculate the rate of change between 3 and 4 branches.
x y
2 42
3 75
4 100
5 119
What is the rate of change?
Answer:
25Step-by-step explanation:
The rate of change of number of tree y on x branches of a tree is expressed as shown;
m = Δy/Δx where;
m is the rate of change
Δy is the change in number of leaves between 3 and 4
Δx is change in number of branches between 3 and 4
m = Δy/Δx = y₂-y₁/x₂-x₁
From table between 3 and 4, y₂ = 100, y₁ = 75, x₂ = 4, x₁ = 3
m = 100-75/4-3
m = 25/1
m = 25
Hence the rate of change between 3 and 4 branches is 25

Step-by-step explanation:
Step 1: Use tan to find angle y
o = 10
a = 8
[tex]tan()=\frac{o}{a} \\tan(y)=\frac{10}{8} \\y = tan^{-1} (\frac{10}{8})\\y = 51.3[/tex]
Therefore angle "y" is 51.3° rounded to the nearest tenth

The shoe size for all the pairs of shoes in a person closet are recorded. what is the mean
Answer:
The mean size of the shoe is 7.
Step-by-step explanation:
We are given the shoe size for all the pairs of shoes in a person closet below;
X = 7, 7, 7, 7, 7, 7, 7, 7, 7, 7.
And we have to find the mean of the data.
Let X = shoe size for all the pairs of shoes
As we know that the mean of any discrete data is given by the following formula;
Mean, [tex]\bar X[/tex] = [tex]\frac{\text{Sum of all the observations}}{\text{Total number of observations}}[/tex]
Here, the number of observations = 10
= [tex]\frac{7+7+7+7+7+7+7+7+7+7}{10}[/tex]
= [tex]\frac{70}{10}[/tex] = 7
Hence, the mean size of the shoe is 7.

Answer:
49 feet
Step-by-step explanation:
We solve for this using proportion
Height of Jack's house = ?? = Y
Length of the shadow of Jack's house = 56 feet
Height of a tree = 21 feet
Length of the shadow of the tree = 24 feet
Height of Jack's house/ Shadow of Jack's house = Height of a tree/ Shadow of the tree
Y/56 = 21/24
Cross Multiply
24 × Y = 56 × 21
Y = 56 × 21/24
Y = 1176/24
Y = 49 feet
Therefore, the height of Jack's house is 49 feet
