inches.
The length and width is 32 inches and 10 inches.
Let us assume the width of rectangle be w. So, length of rectangle = 3w + 2. As per the known fact, the length and width of rectangle for perimeter is related as - Perimeter = 2 (length + width)
Keep the values in formula to find the value of width
84 = 2 (3w + 2 + w)
Performing addition in bracket
84 = 2 (4w + 2)
Performing multiplication
84 = 8w + 4
8w = 84 - 4
Performing subtraction
8w = 80
w = 80 ÷ 8
Performing division
w = 10 inches
Finding length now -
Length = 3×10 + 2
Length = 30 + 2
Length = 32 inches
Hence, the length and width is 32 inches and 10 inches.

Find the slope-intercept form of the line through (−1,3) and (7,−8)
Answer:
[tex]\sf y =\dfrac{-11}{8}x +\dfrac{13}{8}[/tex]
Step-by-step explanation:
Slope-intercept form: y = mx + bHere, m is the slope and b is the y-intercept.
( -1, 3) ; x₁ = -1 & y₁ = 3
(7, -8) ; x₂ = 7 & y₂ = -8
Slope can be obtained by the formula:
[tex]\sf \boxed{\bf Slope = \dfrac{y_2-y_1}{x_2-x_1}}[/tex]
[tex]\sf =\dfrac{-8-3}{7-[-1]}\\\\\\=\dfrac{-8-3}{7+1}\\\\\\=\dfrac{-11}{8}[/tex]
Now, we can find the y-intercept,
[tex]\sf y = \dfrac{-11}{8}x + b\\\\Substitute \ any \ one \ of \ the \ point \ in \ the \ above \ equation.\\\\\text{Here, we are substituting (-1 ,3)}\\\\3 = \dfrac{-11}{8}*(-1) + b\\\\3 = \dfrac{11}{8}+b\\\\b = 3 - \dfrac{11}{8}\\\\b = \dfrac{3*8}{1*8}-\dfrac{11}{8}\\\\b= \dfrac{24-11}{8}\\\\b= \dfrac{13}{8}[/tex]

4m - t=m, for m
Solving for M
The solution of the given equation 4m - m - t = 0 for m is t/3.
According to the given question.
We have a linear equation in two variables i.e. 4m - t = m.
As we know that, an equation is said to be linear equation in two variables if it is written in the form of ax + by + c=0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.
Since, we have to solve the given equation 4m - t = m for m. So, the solution of the equation 4m - t = m for m is given by
4m - t = m
⇒ 4m - m - t = 0 (subtracting m both the sides)
⇒ 3m - t = 0
⇒ 3m = t (adding t both the sides)
⇒ m = t/3.
Hence, the solution of the given equation 4m - m - t = 0 for m is t/3.

What is tangent?The tangent line to a plane curve at a given point is the straight line that "just touches" the curve at that point
Given
f at x=3 is y= 4x+2
g at x=3 is y=6x-1
f(3)= 4x+2 and g(3)=6x-1
y=f(x)g(x)

An equation to answer the question of how many people must attend the third show to have an average attendance of 3,000 when the other show attendance numbers are 2580, and 2920 is 9,000 = 2,580 + 2,920 + x.
What is an equation?An equation is a mathematical expression or statement that shows that two values are equal.
An equation uses the equation mark (=).
Data and Calculation:To have an average attendance per show of 3,000 for three shows, a total of 9,000 people must attend the three shows (3,000 x 3).
Attendance for the first show = 2,580
Attendance for the second show = 2,920
Total attendance for the two shows = 5,500
Required attendance for the third show, x = 9,000 = 2,580 + 2,920 + x
x = 9,000 - 5,500
x - 3,500

A sequence starting with 0 but each number is two times three less than the previous number
The sequence starting with 0 but each number is two times three less than the previous number is as follows:
0, -6, -12, -18, -22
How to find sequence?A sequence is defined as an arrangement of numbers in a particular order.
The most common sequence are the arithmetic and the geometric sequence.
The sequence starts with 0 but each number is two times three less than the previous number.
This means the first term of the sequence is 3.
Hence,
2 times 3 less than the previous number means:
Aₙ = Aₙ₋₁ - 2(3)
where,
n = number of termsLet's use the formula to find the other numbers in the sequence,
A₂ = A₂₋₁ - 2(3) = 0 - 6 = -6
A₃ = A₃₋₁ - 2(3) = -6 - 6 = -12
A₄ = A₄₋₁ - 2(3) = -12 - 6 = - 18
A₅ = A₅₋₁ - 2(3) = -18 - 6 = - 22

To make a sand sculpture Arthur used 2 cm³ of red sand with a density of 4 g/cm³ 7 cm³ of yellow sand with a density of 5 g centimeter and 5 cm³ of brown sand with a density of 6 g cubiccm³ what is the average density of the sculpture in grams per cubic centimeter express your answer as decimal to the nearest 10th.
Answer:
5.2 g/cm³
Step-by-step explanation:
Given a sculpture consisting of 2 cm³ at 4 g/cm³, 7 cm³ at 5 g/cm³, and 5 cm³ at 6 g/cm³, you want its average density.
MassThe total mass of the sculpture is the sum of the masses of the components. Each of those is the product of its volume and density.
red sand: (2 cm³)(4 g/cm³) = 8 g
yellow sand: (7 cm³)(5 g/cm³) = 35 g
brown sand: (5 cm³)(6 g/cm³) = 30 g
The total mass of the sculpture is ...
total mass = 8 g + 35 g + 30 g = 73 g
VolumeThe total volume of the sculpture is the sum of the volumes of its parts:
total volume = 2 cm³ +7 cm³ +5 cm³ = 14 cm³
Average densityThe density is the ratio of mass to volume:
ρ = (total mass)/(total volume) = (73 g)/(14 cm³) = 73/14 g/cm³
= 5 3/14 g/cm³ ≈ 5.2 g/cm³
The average density of the sculpture is about 5.2 g/cm³.

How long will it take to fill the bin if the machine has to stop for 3 minutes after every

Points S, T, and P lie on a number line. Their coordinates
are 0, 1, and x, respectively. Given SP = PT, what is the value of x?
The value of x associated with the point P on a number line is 0.5.
How to find the locations of a point on a number line
In accordance with the statement, the condition SP = PT means that the locations of points S, T and P on the number line are 0, 1, x, so that S < P < T and that point P is equidistant of points S and T. Then, the location of the missing point is determined by the midpoint formula:
P = 0.5 · S + 0.5 · T
P = 0.5 · 0 + 0.5 · 1
P = x = 0.5
The value of x associated with the point P on a number line is 0.5.
