The average temperature of the week is 80 degrees. The first 3 days have an average of 78 and the average of the last 3 days is 82 degrees, what was the temperature of the middle day?
Answer:
80
Step-by-step explanation:Solution:
step 1 Address the formula, input parameters & values.
Input parameters & values:
The given numbers are 78 & 80
step 2 Find the sum of the given two numbers.
sum = 78 + 80 = 158
step 3 Divide the sum by 2 to get the average.
average = 158/2
= 79
Thus, 79 is an average of positive integers 78 and 80.

work out the median 8, 6, 4, 5, 9,8
Answer:
7
Step-by-step explanation:
the median is the middle and if you order them
4,5,6,8,8,9 then you remove one from each side until you have 6,8 so you go in-between the two (seven)
Answer:
7
Step-by-step explanation:
You need to arrange the numbers in an increasing order:
4 5 6 8 8 9
then you need to count how many values we have in the specific set:
6 total values
now we need to find the middle of our set
4 5 6 II 8 8 9
and then we divide the two numbers next to the middle part (6;8) and divide them by 2
(6+8):2=7

Answer:
Blank 1: 28
Blank 2: 42
Blank 3: 22
Answer: It will take 7 sessions.
Step-by-step explanation:
We already know the 3 blanks from the equation 28x = 42 + 22x
Now to find the answer.
28x = 42 + 22x
Subtract 22x from both sides. This cancels the +22x.
28x - 22x = 42
Subtract 22x from 28x to get 6x
6x = 42
Divide both sides by 6. This undoes the multiplication by 6.
x = 42/6
Divide 42 by 6 to get 7.
x = 7
It will take 7 sessions for the costs to match.

A hot air ballon went from an elevation of 6,669 feet to an elevation of 3,402 in 54 minutes. What was its rate of descent?
Answer:
elevation refers to the height of the balloon. Descent refers to moving down, and rate of descent refers to how quickly the balloon moved down.
In this case, we have a descent of 2,125 feet (initial height of 5,439 - ending height of 3,314). Since it took 34 minutes for the balloon to descend this distance, we divide the descent by the time (2,125/34). This gives us a rate of 62.5 feet per minute.
That means that the balloon traveled downward 62.5 feet every minute. That's a fast moving balloon!

GETS BRAINLIEST AND 30 POINTS ! Describe the dilation of a line segment by a scale factor of 1/2 centered at the origin
Answer:
Following are the solution to this question:
Step-by-step explanation:
A transform is a dilation that has changed the size and shape of such a geometric form.
Segment of let line is:
[tex]\to x_i=x_n+t(x_{n+1} -x_n)\\\\\to y_i=y_n+t(y_{n+1} -y_n)[/tex]
[tex]scale \ factor = \frac{1}{2}[/tex]
The dialling is based on its origin and also the line section, in order to provide new coordinates [tex](\frac{x_n}{2}, \frac{y_n}{2}) , (\frac{x_{n+1}}{2}, \frac{y_{n+1}}{2})[/tex] So, the line segment is unchanged, and also has shorter.

Which expression is equivalent to 2^5(4×+9)
Answer:
128x + 288
Step-by-step explanation:
Given the expression 2^5(4×+9)
on factoring
2^5(4×+9) = 2^5(4x) + 2^5(9)
2^5(4×+9) = 32(4x) + 32(9)
2^5(4×+9) = 128x + 288
Hence the expression is also equivalent to 128x + 288

Answer:
Step-by-step explanation:

2/6 -1/6= 1/6
find common denominator
For [tex]\dfrac{1}{3}-\dfrac{1}{6}[/tex] the fraction will be [tex]\dfrac{1}{6}[/tex] .
Given to us,
[tex]\dfrac{1}{3}-\dfrac{1}{6}[/tex]
To solve this, firstly we need to make the denominators the same, thus taking the LCM of both 3 and 6.
As we know the LCM of 3 and 6 is 6 itself.
So, multiplying and dividing by 2.
[tex]\dfrac{1}{3}\rightarrow \dfrac{1\times 2}{3\times 2}\rightarrow \dfrac{2}{6}[/tex]
Now,
[tex]\dfrac{2}{6}-\dfrac{1}{6} = \dfrac{1}{6}[/tex]
Hence, for [tex]\dfrac{1}{3}-\dfrac{1}{6}[/tex] the fraction will be [tex]\dfrac{1}{6}[/tex] .

Simplifying the expression [tex](3\:.\:2)^5\div (3^2\:.\:2^3)[/tex] so, there is only one power of each base we get [tex]\mathbf{3^3\:.\:2^2}[/tex]
Option D is correct answer.
Step-by-step explanation:
We need to simply the expression [tex](3\:.\:2)^5\div (3^2\:.\:2^3)[/tex] so, there is only one power of each base.
Solving:
[tex](3\:.\:2)^5\div (3^2\:.\:2^3)[/tex]
We can write it as:
[tex]\frac{(3\:.\:2)^5}{3^2.2^3}[/tex]
Now using exponent rule: [tex](a\:.\:b)^m=a^m\:.\:b^n[/tex]
[tex]\frac{3^5\:.\:2^5}{3^2.2^3}[/tex]
Now using the exponent rule: [tex]\frac{a^m}{a^n}=a^{m-n}[/tex] the bases should be same
[tex]3^{5-2}\:.\:2^{5-3}\\=3^3\:.\:2^2[/tex]
So, simplifying the expression [tex](3\:.\:2)^5\div (3^2\:.\:2^3)[/tex] so, there is only one power of each base we get [tex]\mathbf{3^3\:.\:2^2}[/tex]
Option D is correct answer.
