when sarah planted a tree in her yard it was 24 inches tall it grew at a rate of 2.5 inches per month the tree is now 41.5 inches tall how many months has it been since sarah planted the tree
In linear equations, 103.75 inches per month tall has it been since sarah planted the tree.
What are instances of linear equations?
Ax+By=C is the usual form for two-variable linear equations. A standard form linear equation is, for instance, 2x+3y=5.When an equation is given in this format, finding both intercepts is rather simple (x and y).When attempting to solve systems involving two linear equations, this form is also quite helpful.Sarah planted a tree in her yard = 24 inches tall
grew at a rate =2.5 inches per month
When tree is now 41.5 inches tall = 41 . 5 * 2.5

Write the sum. 54+63 as the product of a number and relatively prime addends
54 + 63 = 13 * 9 is the expression obtained as the product of a number and relatively prime addends.
A prime number is a number that can be divided only by 1 and itself.
54+63 (given)
We now have to find the sum of the given numbers as the product of relatively prime numbers.
In order to find the numbers we will find first sum and then factor
Sum=54+63=117
Factors of 117 are 13 and 9
117 = 13 * 9
13 and 9 are relatively prime because the factor of 13 and 9 is 1.

An agency charges $100 per person for a trip to a concert if 50 people travel in a group. But for each person above the 50, the amount charged for each traveler will be reduced by $3. If x represents the number of people above the 50, write the agency's revenue R as a function of x. (Assume that x is greater than zero.)
R(x)
The revenue of the the agency is given by the function
R(x) = 5000 - 50 x - 3x² .
A function is a relationship between an independent variable and a dependent variable which defines all points on a cartesian plane which satisfies the given condition.
The set of the independent variables is called a domain and the set of the dependent variable of the function is called a range.Each data in range is related to a particular data in the domain by the function.Now in the given Agency it is given that the charge of each tourist is $100 . Now for every tourist above 50 the charge is reduced by 3 dollars.
So for x people above 50 charge will be ( 100-3 x ) for all members.
The total revenue can be measured by the function
R(x) = ( 50 + x ) ( 100 - 3x )
or , R(x) = 5000 - 150 x + 100 x - 3x²
or, R(x) = 5000 - 50 x - 3x²
Hence the revenue function is given as : R(x) = 5000 - 50 x - 3x²

What is the range of the function f(x) = |x – 5| – 3?
R: {f(x) ∈ ℝ | f(x) > 2}
R: {f(x) ∈ ℝ | f(x) < 2}
R: {f(x) ∈ ℝ | f(x) ≥ –3}
R: {f(x) ∈ ℝ | f(x) ≤ –3}
Reason:
The smallest |x-5| can get is 0 since the result of an absolute value is never negative (because it represents distance).
So the smallest f(x) = |x-5|-3 can get is 0-3 = -3
f(x) = -3 or f(x) > -3 are the only two options for the output f(x).
Condense that into [tex]f(\text{x}) \ge -3[/tex] to arrive at choice C as the final answer.
The fancy notation of f(x) ∈ ℝ translates to "f(x) is a real number".

the following table lists the ages and number of players per age group that are on a volleyball team. let A = (volleyball players who are younger than 8 years old) how many players are in the complement of A?
The number of elements in the complement of a set A is the total number of elements in the universal set minus the number of elements in the set A.
It is given that A={volleyball players who are younger than 8 years old}.
From the table, volleyball players who are younger than the age of 8, are players who are 7 years old.
Hence, the number of players in A is 5.
Add the number of players for each age to get the total number of players:

Describe how the change affects the volume of the prism or pyramid. Multiplying the height by 3/2.
Answer:
1512 cm²
Volume is also multiplied by [tex]\dfrac{3}{2}[/tex]
Step-by-step explanation:
The volume of a pyramid is given by the expression
[tex]V = \dfrac{1}{3} l\cdot w\cdot h[/tex]
where l = base length, w = base width and h = height
The volume of this pyramid
[tex]= \dfrac{18\cdot 12\cdot 14}{3} = 1008\; cm^3[/tex]
If we multiply the height by [tex]\dfrac{3}{2}[/tex] then new height
= [tex]14 \cdot \dfrac{3}{2} = 21 cm[/tex]
New Volume [tex]= \dfrac{18\cdot 12\cdot 21}{3} = 1512\; cm^3[/tex]
[tex]\dfrac{\text{NewVolume}}{\text{Old Volume}} = \dfrac{1512}{1008} = \dfrac{3}{2}[/tex]
So volume is also multiplied by 3/2

What is the range of f(x) = |x| − 5?
−∞ < y ≤ −5
−5 ≤ y < ∞
0 ≤ y < ∞
5 ≤ y < ∞
Answer:
B) - 5 ≤ y < ∞============================
Given function:f(x) = |x| − 5This is an absolute value function and is the translation of f(x) = |x| down by 5 units.
We know that f(x) = |x| is never negative as per definition of absolute value. So its range is zero or positive numbers:
0 ≤ y < ∞
The given function (|x| - 5) can get values 5 less than the parent function (|x|), so its range is:
- 5 ≤ y < ∞This is option B.
5. Which of the following is a rational number that can be written as a decimal in which one or more nonzero digits repeat?
The rational number that can be written as a decimal in which one or more nonzero digits repeat is given by:
D. 5/9.
Which numbers compose the set of rational numbers?The set of rational numbers is composed by numbers that can be represented by fractions, such as numbers that have no decimal parts, or numbers in which the decimal parts are terminating or repeating.
For this problem, we have a focus on numbers that have repeating decimal part. The most known case is the division by 9, as when an integer that is not a multiple of 9 is divided by 9, the result is a decimal with a repeating decimal part.
To find the equivalent decimal to 5/9, we divide the numerator of 5 by the denominator of 9, hence:
5/9 = 0.55555...
The decimal digit 5 repeats infinitely, hence option D is correct.

You have a rectangular prism whose cross section is a square with side length
3 cm. You need to know its length, but you do not have a ruler. Luckily, you have a calibrated container of water nearby. The container has marks that measure cubic centimeters of liquid. It appears to have 70 cubic centimeters of water in it, but when you submerge the prism into the water, the water level rises to the 115-cubic-centimeter mark. Determine how long your prism is.
Answer:
side length = 5cm
Step-by-step explanation:
The volume of the prism is:
V = l × w × h
But we only know the width and height which are both 3cm. See image.
We put it in the calibrated container (container with markings on it) We find out the volume is 45. Because 115 - 70 is 45.
Divide to find the missing length. See image.
Vol
= 3 × 3 × sidelength
V = 9s
45 = 9s
5 = s

a=3 and b=6 and c=5 what is ab+bc?
Answer:
you have the values of a, b and c
all you gotta do is just plug them in so
ab+bc is (3)(6)+(6)(5)
which equals 48.
Answer:
48
Step-by-step explanation:
since a=3, b=6 and c=5, you would replace the letters in ab+bc with their numbers, making it (3)(6)+(6)(5). then you would multiply 3 x 6 which would be 18, and 6 x 5, which would be 30, making your expression 18+30. finally you would add them together, making it 48.
- 2(m - 2) = - 3(m = 5)

What is the numerical value of m in the given equation?Given the data in the question;
-2(m - 2) = -3(m + 5)m = ?To determine the numerical value of m, remove the parenthesis and simplify.
-2(m - 2) = -3(m + 5)
Apply distributive property
-2(m - 2) = -3(m + 5)
m(-2) - 2(-2) = m(-3) + 5(-3)
-2m + 4 = -3m - 15
Now, collect like terms by bring all values containing variable m to the left and all constant to the right side of the equation.
-2m + 3m = -15 - 4
m = -15 - 4
m = -19
