Answer:
5 1/2 or 5.5
Step-by-step explanation:
First, we can convert these values to improper fractions, where the numerator is larger than the denominator.
Then, we'd get:
3/2 x 11/3
Now, we can multiply the numerators and denominators, and we would get the answer of 33/6
When we convert 33/6 to a mixed number, we get 5 3/6, which can then be further simplified to 5 1/2 OR 5.5 (whichever you prefer)

The sum of the first 3 terms of a geometric series is 171 and the common ratio is 2/3. What is the first term of this series
The first term of the series such that the sum of the first three terms of the geometric series is 171 is equal to 81.
What is the first term of a geometric series?
In this problem we find the sum of three consecutive elements of a geometric series. A geometric series is a set of elements generated by a discrete exponential expression of the form:
y = a · rⁿ ⁻ ¹
Where:
a - First term of the series.r - Common ration - Index fo the element.According to the statement, we find the following expression:
a · (2 / 3)² + a · (2 / 3)¹ + a · (2 / 3)⁰ = 171
(4 / 9) · a + (2 / 3) · a + a = 171
(19 / 9) · a = 171
a = 81
Then, the first term of the series is:
y = 81 · (2 / 3)¹ ⁻ ¹
y = 81

Using her garden hose, Camilla filled up a 4-gallon bucket in just
1
6
of a minute. At what rate does water flow through the hose?
Simplify your answer and write it as a proper fraction, mixed number, or whole number.
gallons per minute
If Camila filled up a 4-gallon in just 1/6 of a minute, then the rate of water flow through the hose is 24 gallons/minute
Camila filled up a 4-gallon bucket in just 1/6 of a minute
Here we have to use the unitary method to find the rate of water flow through the hose
The quantity of water filled in 1/6 of a minute= 4 gallon
The quantity water filled in one minutes = The quantity of water filled in 1/6 of a minute ÷ (1/6)
Substitute the values in the equation
= 4÷(1/6)
= 4×6
= 24
The rate of water flow through the hose = 24 gallons/ minute
Hence, if Camila filled up a 4-gallon in just 1/6 of a minute, then the rate of water flow through the hose is 24 gallons/ minute

Write the linear equation that gives the rule for this table X 2,3,4,5 Y 1,2,3,4
Answer: [tex]Y=X-1[/tex]
Step-by-step explanation:
The standard linear equation for the table is expressed as y = mx + b with
m as the slope of the line and b as the y-intercept.
We will use coordinates (2,1) and (3,2) from the table to calculate the slope, m.
[tex]\begin{equation}\begin{aligned}m &=\frac{Y 2-Y 1}{X 2-X 1} \\m &=\frac{2-1}{3-2} \\m &=\frac{1}{1} \\m &=1\end{aligned}\end{equation}[/tex]

Which interval describes where the graph of the function is negative?
The interval that describes where the graph of this function is negative is: C. 2 < x < ∞
What is a graph?A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.
Generally speaking, a function is typically used for mapping an input variable to an output variable. In Mathematics, the value of y on the y-axis of a graph must be less than 0 (x < 0) for the graph of any function to be negative.
By critically observing the graph of this function, we can logically deduce that at point x = 2 is where the value of y becomes less than 0 (x < 0) and continues to infinity. Therefore, the graph of this function is negative is at an interval of 2 < x < ∞.

Looking at this proof of the Pythagorean Theorem, which statement would be true?
Answer: a
Step-by-step explanation:
We know that [tex]a^2 +b^2 =c^2[/tex]. The left hand side is the same as the sum of the areas of the two green squares, and the right hand side is the same as the area of the one large green square.
Identify the equation of the line that is perpendicular to y = −12x +7 and passes
through the point (8, 5).
The equation of the line that passes through the point (8, 5) and perpendicular to y = −12x +7 is y = (1/12)x + 13/3.
We know that,
The product of the slopes of two perpendicular lines is -1.
The slope intercept form of a line is given by :-
y = mx + c
Comparing it with y = -12x + 7
We get,
m = -12 (slope of the line)
c = 7 (y-intercept of the line)
Let the slope of the line perpendicular to the given line be n.
Hence, we can write,
(-12)*n = -1
n = 1/12
Also, the line passes through (8,5).
Hence, we can write,
5 = (1/12)(8) + c
5 = 2/3 + c
c = 5 - 2/3 = 13/3
Hence, the equation of the line is given by :-
y = (1/12)x + 13/3
