The temperature, in °C, of a solution t minutes after being cooled is
60(5/6)^t
After how many
minutes will the temperature of the solution be less than 30°C for the first time?
Answer:
t < 3.8 minutes
Step-by-step explanation:
We are told that the temperature "t" minutes after being cooled is
60(5/6)^t
We want to find After how many
minutes will the temperature of the solution be less than 30°C
Thus;
60(5/6)^t < 30
Divide both sides by 60 to get;

x = number of $200 tickets
y = number of $250 tickets
200 (200 - 1) + 250y = 44,000

can anyone solve 84=4(1 - 4g) step by step?
Answer:
g= -5
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
84-(4*(1-4*g))=0
84 - 4 • (1 - 4g) = 0
3.1 Pull out like factors :
16g + 80 = 16 • (g + 5)
16 • (g + 5) = 0
4.1 Solve : 16 = 0
This equation has no solution.
A a non-zero constant never equals zero.
4.2 Solve : g+5 = 0
Subtract 5 from both sides of the equation :
g = -5

Answer:
g = -5
General Formulas and Concepts:

Step-by-step explanation:
Step 1: Define equation
84 = 4(1 - 4g)
Step 2: Solve for g
Distribute 4: 84 = 4 - 16gIsolate g term: 80 = -16gIsolate g: -5 = gRewrite: g = -5Step 3: Check
Plug in g into the original equation to verify it's a solution.
Substitute in g: 84 = 4(1 - 4(-5))Multiply: 84 = 4(1 + 20)Add: 84 = 4(21)Multiply: 84 = 84Here we see that 84 does indeed equal 84.
∴ g = -5 is a solution of the equation.

Submit what’s r
After the solution of the two-step equation, we can conclude that R = 5.
What do we mean by two-step equations?A two-step equation is one that must be solved in two steps. First, we must eliminate any constants that are on the same side as the variable. To solve, isolate the variable by itself using inverse operations. Remember that whatever you do to one side must be done to the other.So,
Given: R/4 - 9.8 = 10.2Then,
R/4 - 9.8 = 10.2R/4 - 9.8 + 9.8 = 10.2 + 9.8R/4 = 20R = 20/4R = 5Therefore, the value of R is 5.

the first term of an arthimetic sequence is 42 the rule an= an-1 +8 can 1 can be used explain how to write explict rules
Answer:
34 + 8n
Step-by-step explanation:
a₁ = 42
[tex]a_{n} = a_{n-1} + 8[/tex]
a₂ = a₁ + 8 = 42 + 8 = 50
a₃ = a₂ + 8 = 50 + 8 = 58
a₄ = a₃ + 8 = 58 + 8 = 66
Arithmetic sequence: 42, 50 , 58 , 66, ......
a₁ = 42 ; d = 8
[tex]a_{n}[/tex] = a₁ + d(n-1)
= 42 + 8(n - 1)
= 42 + 8n - 8
= 34 + 8n
Answer:
[tex]a_{n}[/tex] = 8n + 34
Step-by-step explanation:
The explicit rule for an arithmetic sequence is
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Given the recursive rule
[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 8
where + 8 is the common difference d , then
[tex]a_{n}[/tex] = 42 + 8(n - 1) = 42 + 8n - 8 = 8n + 34
Explicit rule is
[tex]a_{n}[/tex] = 8n + 34

The main purpose of EFA is to find out the relationship between variables.
EFA is an abbreviation for exploratory factor analysis, which is used to determine the link between variables that are assessed.Exploratory factor analysis is a statistical tool used in multivariate statistics to find the underlying structure of a rather large set of variables. EFA is a factor analysis approach with the overriding purpose of identifying the underlying connections between measured variables.The common factor concept underpins EFA. Manifest variables are expressed as a function of common components, unique factors, and measurement errors in this model. Each distinct component has an effect on only one manifest variable and does not explain relationships between manifest variables. Common factors impact several manifest variables, and "factor loadings" are measurements of a common factor's influence on a manifest variable.To learn more about statistics, visit :

Use the area of the rectangle to find the area of the triangle.
4 ft
8 Ft
Answer:
The area of the triangle is 16 feet because the are of the rectangle is 32 feet.
Step-by-step explanation:
The length of the rectangle is 8 feet. Since the dotted line is exactly in the middle of the rectangle, the bottom of the triangle s 4 feet. With 4 feet as the bottom and 4 as the height, we can calculate the area of one of the triangles ( 4 * 4 /2 ), so each of the triangle's area is 8 feet. Add them together, and you get 16!

How many solutions for 3(2x+5)-6x=40
The given linear equation can be simplified to:
15 = 40
Which means that the equation has no solutions.
How many solutions we have for the given equation?
Here we have the linear equation:
3*(2x + 5) - 6x = 40
And we want to see how many solutions does this equation has.
The solutions are the values of x such that the equation becomes true.
Then we can rewrite:
3*(2x + 5) - 6x = 40
Distributing the product we get:
3*2x + 3*5 -6x = 40
6x + 15 - 6x = 40
(6x - 6x) + 15 = 40
15 = 40
Notice that this equation does not depend of x, and it is false, (15 is not equal to 40)
So there are no value of x such that the equation is true, which means that the linear equation has no solutions.

The rectangle shown has a perimeter of 54 cm and the given area. Its length is 3 more than twice its width. Write and solve a system of equations to find the dimensions of the rectangle. The length of the rectangle is _ cm and the width of the rectangle is _ cm.
Answer:
length of the rectangle is 19 cm and the width of the rectangle is 8 cm.
Step-by-step explanation:
The formula for the perimeter of a rectangle = 2L + 2 W
Where:
L = length and W = width
The rectangle shown has a perimeter of 54 cm
Its length is 3 more than twice its width.
2L + 2W = 54 .... Equation 1
"length is 3 more than twice its width."
L = 2W + 3.....Equation 2
Substituting 2W + 3 for L
We have:
2L + 2W = 54 .... Equation 1
2(2W + 3) + 2W = 54
4W + 6 + 2W = 54
6W = 54 - 6
6W = 48
W = 48/6
W = 8cm
L = 2W + 3.....Equation 2
L = 2(8) + 3
L = 16 + 3
L = 19 cm
Therefore:
length of the rectangle is 19 cm and the width of the rectangle is 8 cm.
