Answer:
[tex]Width = 2\frac{1}{4}cm[/tex]
[tex]Length=5\frac{5}{12} cm[/tex]
Step-by-step explanation:
Data from the question;
Perimeter of a rectangle is [tex]15\frac{1}{3}[/tex] cm
Length is [tex]3\frac{1}{6}[/tex] cm longer than the width
We are supposed to determine the length and the with of the rectangle;
Assuming, the width x cm
Then, the length is [tex]x+3\frac{1}{6}[/tex] cm
We need to know that the perimeter of a rectangle is given by;
Perimeter = 2 ( length + width)
Therefore;
[tex]15\frac{1}{3}= 2 ( x + (x+3\frac{1}{6}))[/tex]
[tex]15\frac{1}{3}=2(2x+3\frac{1}{6})[/tex]
Thus;
[tex]15\frac{1}{3}=4x+6\frac{1}{3}[/tex]
[tex]4x=9\\x=2\frac{1}{4}[/tex]
Therefore;
[tex]Width = 2\frac{1}{4}cm[/tex]
[tex]Length = x + 3\frac{1}{6}[/tex]
[tex]=2\frac{1}{4}+3\frac{1}{6}[/tex]
[tex]=5\frac{5}{12} cm[/tex]
Therefore; the length is [tex]5\frac{5}{12}[/tex] cm while the width is [tex]2\frac{1}{4}[/tex] cm

What is the location of the point on the number line that is 4/9 of the way from
A= -8 to B = 10?
Ο Α. 0
OB. 2
O c. -2
O D. -1
Answer:
Α. 0
Step-by-step explanation:
Given A = -8 and B = 10
The distance between A and B
= B - A

7y+3=4y−18
y = ___
(type your answer as a number)
Answer:
y = -7
Step-by-step explanation:
To solve for 'y', we need to isolate it, meaning to separate it from everything else. You move numbers in the equation around by canceling them out, which you do with opposite or reverse operations. (Addition and subtraction are opposites. Division and multiplication are opposites).
First, bring all of the numbers with 'y' to the left, and bring all of the numbers without 'y' to the right. Then isolate y.
7y + 3 = 4y - 18 Move 'y' to the left.
7y - 4y + 3 = 4y - 4y - 18 Subtract 4y from both sides.
7y - 4y + 3 = -18 Notice 4y - 4y cancelled out. Combine like terms on the left. 7y and -4y both have 'y'.
3y + 3 = -18 Move the numbers to the right.
3y + 3 - 3 = -18 - 3 Subtract 3 from both sides.
3y = -18 - 3 +3 and -3 cancelled out. Combine like terms on right.
3y = -21 Cancel out the '3' attached to 'y'.
3y/3 = -21/3 Divide both sides by 3.
y = -21/3 3y/3 becomes just 'y' because 3 ÷ 3 is 1.
y = -7 Answer for y.

how can u use volume and surface area to solve real world problems
Answer:
You could use surface area to find the amount of wrap needed for a bale. You could use surface area to figure out how much frosting is needed to frost a cake. You could use surface area to find out how much paint is needed to paint a house.
Step-by-step explanation:
Surface area and volume have numerous real-world applications. They are employed in Biology to understand cell functioning, in Physics to calculate celestial volumes, and in Environmental Studies to assess pollution levels and treat diseases. Accurate measurements and unit consistency are crucial for these applications.
Explanation:Volume and surface area can be implemented in an array of real-world scenarios. For instance, in Biology, the calculation of surface area to volume ratios is essential in understanding how cells function. Larger cells have a smaller surface area to volume ratio, which can impact how efficiently they can transfer nutrients or remove waste. If the cell becomes too large, it might not be able to sustain itself sufficiently with the nutrients absorbed, or remove waste effectively. Thus, we see here that surface area to volume ratios can even be essential for life itself.
In Physics, we can extrapolate the volume of Earth's oceans or the galaxy by observing specific measurements. Volume calculations are also used in Engineering and Construction to estimate the quantity of material needed for a particular project. In Environmental Studies, we can evaluate the pollution affecting species habitat or resolve diseases impacting humans, using these geometric concepts.
In all these cases, a consistent usage of appropriate units (likes meters, kilograms, and others depending on the context) is key to getting accurate results. Also, bear in mind that the application of these mathematical concepts often requires creativity and insight to solve problems effectively.

determine whether each pair of functions are inverse functions. 1) f(x)=10x+9/8, g(x)=25x-9/10 2) f(x)=x-9, g(x)=x+9
a. both 1 and 2 are inverse functions.
b. only 2 is an inverse function
c. brother 1 nor 2 is an inverse function.
d. only 1 is an inverse function
Final answer:
After analyzing both pairs, it is evident that only the second pair, f(x) = x - 9 and g(x) = x + 9, meet the requirements for inverse functions, as both compositions f(g(x)) and g(f(x)) return the original input x. Hence, option b: only 2 is an inverse function, is correct.
Explanation:
To determine whether each pair of functions are inverse functions, we must check if applying one function following the other returns the original input value. For two functions, f(x) and g(x), to be inverses of each other, the following must hold true:
f(g(x)) = x
g(f(x)) = x
Pair 1: f(x) = 10x + 9/8, g(x) = 25x - 9/10
Applying g to f:
g(f(x)) = g(10x + 9/8) = 25(10x + 9/8) - 9/10
After simplifying, this does not equal x, so f and g are not inverse functions.
Pair 2: f(x) = x - 9, g(x) = x + 9
Applying g to f:
g(f(x)) = g(x - 9) = (x - 9) + 9 = x
Applying f to g:
f(g(x)) = f(x + 9) = (x + 9) - 9 = x
In the second pair, both compositions return the input x, so f and g are inverse functions of each other. Therefore, the answer is option b: only 2 is an inverse function.

how many integers from 1 to 1 million dont have common factors with 2020
Is -3.5 greater than -1.5
Answer:
No.
Step-by-step explanation:
On the number line, a number is greater than a number to its left. For example, 3 is to the left of 5, so 5 is greater than 3.
On the number line, -3.5 is to the left of -1.5, so -1.5 is greater than -3.5.
After comparing the given two negative numbers we conclude that,
the number -3.5 is not greater than -1.5.
A negative number is one that always has a value lower than zero and is denoted by the minus (-) symbol.
The given numbers are,
-3.5 and -1.5
Subtract -1.5 from -3.5
-3.5 - (-1.5)
Remove bracket by multiplying signs,
-3.5 + 1.5
= -2.0
Now it can be written,
-3.5 = -1.5 - 2.0
Since,
-1.5 - 2.0 < -1.5
Therefore,
-3.5 < -1.5
Hence,
The number -3.5 is not greater than -1.5.

A board is leaning against a building so
that the top of the board reaches a
height of 18 feet. The bottom of the
board is on the ground 4 feet away from
the wall. What is the slope of the board
as a positive number?
The slope of a line is given by rise over run. The slope of the board leaning against the building is 4.5; given by the height it reaches (18 feet) divided by the distance from the base of the building to the base of the board (4 feet).
Explanation:The subject of your question is the slope of a line in a mathematical context, specifically when dealing with the Algebra of Straight Lines. First, let's recall what slope is. The slope of a line, commonly represented as m, is the measure of the vertical change (rise) for each unit of horizontal change (run).
To find the slope of the board leaning against the building, we can take the rise over the run. Here, the rise is the height of the building which the board reaches - 18 feet. The run is the distance from the building to the board's base on the ground - 4 feet. Hence, the slope m of the board would be calculated as follows: m = rise/run = 18/4 = 4.5.
A positive slope indicates that the line rises from left to right, like the board leaning against the building. So, the slope of the board as a positive number is 4.5.

17.1%
20.7%
34.0%
43.2%
Answer:
17.1
Step-by-step explanation:
Final answer:
The percent change in total computer sales from June to July cannot be calculated without the specific numerical sales data for each model. We need the quantities sold in May and June to determine the rate of change and project this to July.
Explanation:
To determine the percent change in total computer sales from June to July, based on the provided sales chart data, we first need to calculate the change from May to June for each computer model separately. If we assume that the sales data numbers in the chart represent the quantity of computers sold, we can take the difference in sales of each model between the two months and then sum these differences to get the total change in sales. Afterward, we'll need to express this total change as a percentage of the total sales in June.
However, the actual sales data with quantity figures are not provided; hence, we cannot calculate the exact percent change. The question seemingly requires specific numerical data to calculate the change in percentage, which is not included in the text above. Without such data, it is impossible to provide a step-by-step solution to the question regarding calculating the percent change in total computer sales.
