The glass part of a window is 32 1/2 inches wide. Including the frame on the left and right sides, the total width is 42 inches. If the left and right frames are equal, what is the width of each side of the frame?
The glass part of the frame is an illustration of fractions
The width of each side of the frame is 5 1/4 inches
How to determine the width of each side?The given parameters are:
Total width = 42 inchesGlass part = 32 1/2 inchesRepresent the width of each side with x.
So, we have:
Glass part + 2x = Total width
Substitute known values
31 1/2 + 2x = 42
Subtract 31 1/2 from both sides
2x = 10 1/2
Divide both sides by 2
x = 5 1/4
Hence, the width of each side of the frame is 5 1/4 inches

Please Someone Help Me With This Question
Answer:
B
Step-by-step explanation:
One easy way to solve this (considering it's on paper) would be to just plot the points of each option (because a rectangle is a quadrilateral which is equiangular (right angles) and a parallelogram).
Another way to solve this is the fact that it's angles are right angles. This means that a point has to be on the line y=5 and another point has to be on the line y=1. This means that the y coordinates of the other two points has to be 5 or 1, making the only possible answer B.

The average monthly temperature in New Orleans, LA has a mean absolute deviation of 43.5*F what conclusion can you make about the average monthly temperatures in New Orleans, La.
The average monthly temperature in New Orleans, LA varies on average about 43.5°F from its monthly mean temperature.
How to find the mean absolute deviation of a discrete data?Suppose the data specified is of n sized as
[tex]x_1, x_2, \cdots , x_n[/tex]
Let this data's mean be [tex]\bar{x}[/tex]
Then, the mean absolute deviation of this data is the mean of the absolute differences of the observations from the mean of the data they belong to.
It is calculated as:
[tex]M.A.D = \dfrac{\sum_{i=1}^n|x_i-\bar{x}|}{n}[/tex]
So, Mean Absolute deviation is the average of the deviation (not caring if its above or below the mean) of the data values.
Since it is given that:
Mean absolute deviation of the temperatures (monthly) in New Orleans = 43.5°F, therefore, it means, the temperature averagely varies 43.5°F from its monthly average value.
where mean shows the average monthly temperature in New Orleans, LA.
Thus, the average monthly temperature in New Orleans, LA varies on average about 43.5°F from its mean temperature.

Your friend asks you to help him study and will pay you 5 dimes the first time you help him. You agree to help if he multiplies your payment by 5 for each study session. After 2 study sessions, you will receive 25 dimes, and after 3 study sessions, you will receive 125 dimes.
Complete and solve the equation that finds the number of dimes he will pay you after the 7th study session.
Answer:
78125 dimesStep-by-step explanation:
The payment for sessions makes a series
5 dimes, 5*5 = 25 dimes, 25*5 = 125 dimes, ...This series is GP with the first term of 5 and common ratio of 5.
The nth term would be
[tex]t_n=5*5^{n-1}[/tex]Use the equation above and find the 7th term
[tex]t_7=5*5^6 = 5^7 = 78125[/tex]Answer:
[tex]a_7=5(5)^{6}[/tex]
78125 dimes
Step-by-step explanation:
The given scenario can be modeled as a geometric sequence.
A geometric sequence has a common ratio (multiplier) between each term, so each term is multiplied by the same number.
General form of a geometric sequence:
[tex]a_n=ar^{n-1}[/tex]
where:
n is the nth terma is the first termr is the common ratioGiven:
The friend will pays 5 dimes the first time you help him.Therefore, a = 5
Given:
The friend multiplies your payment by 5 for each study session.Therefore, r = 5
Substitute these values into the formula to create an equation for the nth term.
[tex]\implies a_n=5(5)^{n-1}[/tex]
To find the number of dimes he will pay after 7 sessions, simply substitute n = 7 into the found equation:
[tex]\implies a_7=5(5)^{7-1}[/tex]
[tex]\implies a_7=5(5)^{6}[/tex]
[tex]\implies a_7=5 \cdot 15625[/tex]
[tex]\implies a_7=78125[/tex]
Therefore, the friend will pay 78125 dimes after the 7th study session.
