Answer:
76
Step-by-step explanation:
median is the number in the very center of the list of numbers in order:
64, 72, 72, 80, 85, 89
to find the one in the middle we take away the numbers from both ends:
72, 72, 80, 85
72, 80
since there are two numbers in the middle we’ll find the average
(72+80)/2
152/2
76
Answer:
76
Step-by-step explanation:
Median means middle
so we are looking for the middle number
place the numbers in order and look for the number thats in the middle
64, 72, 72, 80, 85, 89
72 and 80 are both the middle numbers.
Therefore, we add 72+80 and then divide by 2
72+80= 152
152/2= 76
Final answer: 76 is the median

You mean like graph? Yeah.
Write in Function form
[tex]\frac{y-3}{x-6}=2\\y-3=2(x-6)\\y=2(x-6)+3\\y=2x-12+3\\y=2x-9[/tex]
So (y-3/x-6)=2 does represent "line"
[tex]\frac{y-6}{x-4}=5[/tex]
multiply x-4 all side.
[tex]y-6=5(x-4)[/tex]
Notice how the equation is similar to "Tangent" so it's clearly a line.
About reasoning, No idea how to explain but this might help...
Whenever you get rid of the fraction part, it'll leave only y-f(a)=f'(a)(x-a) which is a Tangent Line (It explains it.)
And when you simplify in Function Form, you'll get an exact linear function "[tex]y=mx+b[/tex]"
how do you solve these fractions

Answer:
Step-by-step explanation:
1) [tex]\frac{1}{3}-(\frac{1}{3}*\frac{1}{3}) + (\frac{1}{3}[/tex] ÷[tex]\frac{1}{3}) =[/tex] [tex]\frac{1}{3}-\frac{1}{9} +(\frac{1}{3}*\frac{3}{1})[/tex]
[tex]=\frac{1}{3}-\frac{1}{9}+1\\\\=\frac{1*3}{3*3}-\frac{1}{9}+\frac{1*9}{1*9}\\\\=\frac{3}{9}-\frac{1}{9}+\frac{9}{9}\\\\=\frac{3-1+9}{9}\\\\=\frac{11}{9}\\\\=1\frac{2}{9}\\[/tex]
2)
[tex](3\frac{3}{4}-2\frac{2}{3})*1\frac{1}{2}=(\frac{15}{4}-\frac{8}{3})*\frac{3}{2}\\\\=(\frac{15*3}{4*3}-\frac{8*4}{3*4})*\frac{3}{2}\\\\=(\frac{45}{12}-\frac{24}{12})*\frac{3}{2}\\\\=(\frac{45-24}{12})*\frac{3}{2}\\\\=\frac{21}{12}*\frac{3}{2}\\\\=\frac{21}{4}*\frac{1}{2}\\\\=\frac{21}{8}\\\\=2\frac{5}{8}[/tex]
3) When finding equivalent fractions both numerator and denominator should be multiplied with the same number. But Lethna didn't multiply with the numerator.
[tex]\frac{2}{5}+\frac{1}{2}=\frac{2*2}{5*2}+\frac{1*5}{2*5}\\\\=\frac{4}{10}+\frac{5}{10}\\\\=\frac{9}{10}[/tex]
4) In fraction multiplication convert mixed fraction to improper fraction and reduce to smallest term
[tex]1\frac{1}{2}*5\frac{1}{3}=\frac{3}{2}*\frac{16}{3}\\\\=8[/tex]
5)
[tex]8\frac{2}{3}*5\frac{4}{9}=\frac{26}{3}*\frac{49}{9}\\\\=\frac{1274}{27}\\\\= 47\frac{5}{27}\\\\[/tex]
6) Use Keep Change Flip (KCF) method for fraction division
[tex]4\frac{2}{5}[/tex] ÷ [tex]6\frac{5}{8}[/tex] = [tex]\frac{22}{5}[/tex] ÷ [tex]\frac{53}{8}[/tex]
[tex]= \frac{22}{5}*\frac{8}{53}\\\\=\frac{176}{265}[/tex]
37a + 45b +1 3c + 26d + 27

What is a linear function?A straight line on the coordinate plane is represented by a linear function.
A linear function always has the same and constant slope.
The formula for a linear function is f(x) = ax + b, where a and b are real values.
The linear function is given as,
y = mx + c
Here, m is the slope while c is the y-intercept.
Slope m = (-13 + 9)/(2 - 1)
m = -4
Put m = -4, (1,-9)
-9 = -4(1) + c
c = -5
y = -4x - 5
Hence "The linear function or equation in the slope-intercept form will be y = -4x - 5".

Which value of x makes the equation 0.5(x + 15) = 2 + 0.75(x - 4) true?
Answer:
Step-by-step explanation:
[tex]\frac{1}{2}(x+15) = 2 + \frac{3}{4}(x-4)[/tex]
To make this easier, to get ride of the fractions, we can multiply both sides by 4
[tex]2(x+15) = 8 + 3(x-4)[/tex]
now use the distributive property
[tex]2x + 30 = 8 + 3x - 12\\[/tex]
now we want to isolate x to one side and isolate all the constants to the other
[tex]2x - 3x = 8 - 12 - 30\\[/tex]
now simplify
[tex]-x = -34\\x = 34[/tex]
to test, we can plug in back to the original
[tex]\frac{1}{2}(34+15) = \frac{49}{2}\\\frac{8}{4} + \frac{3}{4}(34-4) = \frac{8}{4} + \frac{90}{4} = \frac{98}{4} = \frac{49}{2}[/tex]

You plant a spruce tree that grows 4 inches per year and a hemlock tree that grows _____ inches per year. The initial heights are shown. Write a system of linear equations that represents this situation.
Complete Question:
You plant an 8-inch spruce tree that grows 4 inches per year and a 14-inch hemlock tree that grows 6 inches per year.
The initial heights are shown.
Write a system of linear equations that represents this situation.
Answer:
[tex]s(x) = 8 + 4x[/tex]
[tex]h(x) = 14 + 6x[/tex]
Step-by-step explanation:
Given
Spruce Tree (s):
[tex]Initial\ Height = 8[/tex]
[tex]Growth = 4[/tex] (yearly)
Hemlock Tree (h):
[tex]Initial\ Height = 14[/tex]
[tex]Growth = 6[/tex] (yearly)
Required
Represent as system of linear equations
Let the number of years be x.
In both cases, the equation can be formed using:
[tex]Equation = Initial\ Height + Growth * x[/tex]
For Spruce Tree (s):
[tex]s(x) = 8 + 4 * x[/tex]
[tex]s(x) = 8 + 4x[/tex]
For Hemlock Tree (h):
[tex]h(x) = 14 + 6 * x[/tex]
[tex]h(x) = 14 + 6x[/tex]
Hence, the equations are [tex]s(x) = 8 + 4x[/tex] and [tex]h(x) = 14 + 6x[/tex]
Which of the following equations is correct? select three that apply
A) 0.12 = 4/33
B) 0.4 = 2/5
C) 0.54 = 6/11
D) 0.7 = 7/9
E) 0.83 = 5/6
F) 0.91 = 41/45
Answer:b,e,f
Step-by-step explanation:
The correct equations are:
B) 0.4 = 2/5
D) 0.7 = 7/9
E) 0.83 = 5/6
To determine which of the following equations is correct, we need to compare each decimal value to its equivalent fraction. Here are the correct equations:
B) 0.4 = 2/5
D) 0.7 = 7/9
E) 0.83 = 5/6
B) 0.4 is equivalent to 2/5 because 0.4 means 4 tenths, and 2/5 also represents 4 tenths (2 parts out of 5).
D) 0.7 is equivalent to 7/9 because 0.7 means 7 tenths, and 7/9 also represents 7 tenths (7 parts out of 9).
E) 0.83 is equivalent to 5/6 because 0.83 means 83 hundredths, and 5/6 also represents 83 hundredths (5 parts out of 6).
The remaining options (A, C, and F) are not correct as their decimal values do not match their corresponding fractions.

Elle placed a bucket under a leaky roof. The bucket was 3/10 full after 2/5 of an hour. How much water is leaking per hour?
Answer:
The amount of water leaking per hour is 3/4 of the bucket volume
Step-by-step explanation:
The given parameters are;
The volume of water in the bucket = 3/10 of the bucket volume
The time duration of the leak = 2/5 hour
Therefore;
The leak rate = Volume/Time
The amount of water leaking per hour = (3/10 of the bucket volume)/(2/5 hour)
The leak rate = The amount of water leaking per hour = 3/4 of the bucket volume/hour.
The amount of water leaking per hour is [tex]\frac{3}{4}[/tex] of the bucket volume.
Given ;
The volume of water in the bucket = [tex]\frac{3}{10}[/tex] of the bucket volume
The time duration of the leak = [tex]\frac{2}{5}[/tex] hour
Therefore;
The leak rate = [tex]\frac{volume }{time}[/tex]
The amount of water leaking per hour = ( [tex]\frac{3}{10}[/tex] 0f the bucket volume)/([tex]\frac{2}{5}[/tex] hour)
= ( [tex]\frac{3}{10} . \frac{5}{2}[/tex] ) volume per hour
The leak rate = The amount of water leaking per hour = 3/4 of the bucket volume per hour.

Q3.
The length of a car is 3.6 metres.
Karl makes a scale model of the car.
He uses a scale of 1 cm to 30 cm.
Work out the length of the scale model of the car.
Give your answer in centimetres.
The length of the scale model of the car is 120 cm
Working out the length of the scale model of the car.From the question, we have the following parameters that can be used in our computation:
Length of a car = 3.6 meters
We have the scale to be
Scale = 1 cm to 30 cm
This means that
Scale = 1 cm : 30 cm
using the above as a guide, we have the following:
Scale : 3.6 meters = 1 cm : 30 cm
So we have
Scale = 3.6 m * 1 cm/30 cm
Evaluate
Scale = 0.12 m
Convert to cm
Scale = 120 cm
Hence, the length of the scale model of the car is 120 cm
