Answer:
20
Step-by-step explanation:
If length of the base is x, then the other sides are 3x
so x + 3x + 3x = 140
7x = 140
x = 140/7 = 20

Answer:
Is a Factor
Step-by-step explanation:
Part A: describe the type of function
Part B: what are the standard and factored form of the function
Part C: what are the zeros of the function
Part D: use the zeros to find all of the linear factors
Part E: write the equation of the graphed function
Part F: Use the Y intercept of the graph and your equation from part E to calculate the value of a
Part G; write the equation for the function shown in graph
The type of function of the given graph is polynomial in nature.
Each element of X receives exactly one element of Y when a function from one set to the other is used.
The sets X and Y are collectively referred to as the function's domain and codomain, respectively.In mathematics, a polynomial is an expression made up of coefficients and indeterminates that solely uses the operations of multiplication, addition, and non-negative integer exponentiation.A) The given function is a polynomial of the third degree.
B) The factored form of the polynomial is: [tex]-\frac{1}{1500} (x+20)(x+5)(x-15)[/tex]
The standard form is: [tex]p(x)=-\frac{x^3}{1500} -\frac{x^2}{150} +\frac{11x}{60} +1[/tex]
C) The zeroes of the polynomial function are -20, -5 and 15
D) The linear factors are (x+20)(x+5) and (x-15)
E) The equation of the function is [tex]y=-\frac{1}{1500} (x+20)(x+5)(x-15)[/tex]
F) From the graph it is seen that the factors of the polynomial function are (x+20)(x+5) and (x-15).
Now at x=0, y=1.
Substituting these values we get:
1=a(0+20)(0+5)(0-15)
or, a = [tex]-\frac{1}{1500}[/tex]
So the value of a for the equation is [tex]-\frac{1}{1500}[/tex] .
G) The equation for the function in the graph is
[tex]y=-\frac{1}{1500} (x+20)(x+5)(x-15)[/tex]

Answer:
17
Step-by-step explanation:
so x stays the same, so you look at the y integers and to get to the negatives you have to go down 5 times, then 12 more to get to -12. So 5+12= 17

Which fractions have the same value as -1/4? please help!!
(look at picture)
The fractions which have the same value as the fraction given; -1/4 among the answer choices are; -(-1/-4), -1/4 and 1/-4.
What fractions are equivalent to the given fraction; -1/4 as in the task content?It follows from the task content that the fractions which are equivalent to the given fraction; -1/4 are to be identified.
On this note, one must first identify that the quotient or product of like signs (+ or -) yields a positive sign while the quotient or product of unlike signs yields a negative sign.
Hence, the simplified form of the options are as follows;
-(-1/-4) = -1/4.-1/-4 = 1/4-1/4 = -1/4-(-1/4) = +11/-4 = -1/4.Hence, the correct answer choices are; -(-1/-4), -1/4 and 1/-4.

PLS HELP ASAP 60 POINTS AND I'LL GIVE BRAINLIEST! What can you notice about the circumcenter, incenter, orthocenter, and centroid of a triangle? What can you notice about their relationship?
Answer:
The centroid is always between the orthocenter and the circumcenter. The distance between the centroid and the orthocenter is always twice the distance between the centroid and the circumcenter. In obtuse triangles, the circumcenter is always outside the triangle opposite the largest....8x-9+53=180 solve for x
Answer:
x=17
Step-by-step explanation:
1: Simplify both sides of the equation.
8x−9+53=180
8x+−9+53=180
(8x)+(−9+53)=180(Combine Like Terms)
8x+44=180
8x+44=180
2: Subtract 44 from both sides.
8x+44−44=180−44
8x=136
3: Divide both sides by 8.
(8x=136 )/8
x=17
the sum of two numbers is 32 when 5 is subtracted from fourth and one of the number the result is 8 times the other number find the difference between the two numbers
We will need to use the substitution method to solve the question. The difference between the two numbers is 11.5
Substitution method is used to solve a system of equations. First the equation is solved for one variable and then the value is used in the other equation to solve for the other unknown variable. In this question we have been told the sum of two numbers is 32. Let us take the two numbers as x and y. Then we can say that
x+y=32 ...(i)
Next we know that when 5 is subtracted from 4 times one number the result is 8 times the other number, we can write it as
4x-5=8y
4x-8y=5....(ii)
So we have two equations
x+y=32
4x-8y=5
We will multiply equation (i) by 4 to cancel out x and solve for y
4x+4y=128
4x-8y=5
(-) (+) (-)
-----------------
12y=123
y=10.25
We substitute the value of y in equation (i)
x+y=32
x+10.25=32
x=32-10.25=21.75
We need to find the difference between two number which is x-y=21.75-10.25=11.5
Therefore we found out by substitution method that the difference between the two numbers is 11.5

a family of five recently replaced its 5-gallon-per-minute showerheads with water-saving 2-gallon per minute showerheads. each member of the family averages 8 minutes in the shower per day. how many gallons will the entire family (5 people) save per day?
The entire family (5 people) save 120 gallons per day.
Subtraction:
Subtraction means we have to find the difference of the numbers.
Given,
A family of five recently replaced its 5-gallon-per-minute showerheads with water-saving 2-gallon per minute showerheads.
Each member of the family averages 8 minutes in the shower per day.
Here we need to find the entire family savings per day.
According to the question,
The total bath time for the whole family is,
=> 8 x 5 = 40
So for one day,
If the showerheads cost 5 gallon per minute, then the cost for the family is,
=> 40 x 5 = 200
If the showerheads cost 2 gallon per minute, then the cost for the family is,
=> 40 x 2 = 80
So, the savings is,
=> 200 - 80
=> 120
So, they save 120 gallons per day.

The formula for figuring straight-time pay is
your hourly rate divided by the number of
hours worked in a week. T or f
Your hourly wage is divided by the number of hours worked in a week to determine straight-time pay. :- False
The entire set amount of money provided to an employee over a specific time period—typically a year—is referred to as a salary. The amount paid to an employee for each hour of work is known as their hourly wage in comparison.
Let's assume the straight time pay to be x.
Let the hourly pay rate be y
If a person has worked N no. of hours in a week.
Then the straight-time pay will be the product of the hourly pay rate and the number of hours the person worked.
Therefore,
The straight time pay, x = N × y = Ny
Hence, the statement " the formula for figuring straight time pay is your hourly rate divided by the number of hours worked in a week" is false.
