If it decreases by 80٪, then only 20٪ remains.
15×20٪=15×20/100=15×0.2=3
Answer: 3
Answer:
3 arches
Step-by-step explanation:
Given
15 arches decreased by 80%.
First get 80% of 15 arches
That’s 80%/100% x 15
0.8 x 15
12 arches
Now subtract 12 arches from 15 arches to get the decrease
Decrease = (15 - 12) arches
= 3 arches
Therefore, 80% decrease of 15 inches is equal to 3 arches

Graphs of proportional relationships visually depict how two or more variables are interrelated using line graphs, pie graphs, and bar graphs. Line graphs show direct relationships with a constant rate of change, pie graphs represent portions of a whole, and bar graphs compare quantities through the height of bars.
Explanation:When interpreting graphs of proportional relationships, it's essential to recognize that these graphs illustrate how two variables correlate with one another. In line graphs, a straight line that passes through the origin indicates a direct proportionality, meaning as one variable increases, the other increases at a constant rate. For instance, if a line graph shows the relationship between hours worked and income earned, the line's slope denotes the rate of earning per hour, showcasing a proportional increase in income with more hours worked.
Pie graphs are used to represent how a whole is divided into parts, with the size of each 'slice' showing the percentage of the total. An example could be a budget allotment where each slice represents what percentage of the budget is spent on specific categories, like marketing or research and development.
Lastly, bar graphs can also indicate proportional relationships through the height of the bars. For example, if a bar graph displays the population sizes of different countries, each bar's height is proportional to the population of that country. When bars are segmented, they can show subgroups within that population, such as age demographics or income brackets.
Edward owes his parents $20 for a new video
game that he bought. He pays his parents back
$5 every 2 days. Complete the table and graph
to find how long it will take Edward to
pay back his debt.
Answer:
it would take Edward 8 to pay back his debt
Step-by-step explanation:
every 2 days he pays his parents 5 bucks so because 5 times 4 equals 20 he would have to multiply the 4 by 2 and that gets you 8 days
Final answer:
Edward will pay back his $20 debt to his parents by repaying $5 every 2 days; thus, it will take him 8 days in total to repay the full amount.
Explanation:
The question asks us to determine how long it will take for Edward to pay back a $20 debt to his parents if he repays $5 every 2 days. To solve this, we can set up a simple table showing the cumulative amount paid over time, and then establish a corresponding graph if needed. Here's how the repayment schedule works out:
Day 0: $0 paid back
Day 2: $5 paid back (Total: $5)
Day 4: $5 paid back (Total: $10)
Day 6: $5 paid back (Total: $15)
Day 8: $5 paid back (Total: $20)
From the table, it is clear that it will take Edward 8 days to pay back the full $20 debt.

x - y = 19 +
--------------
2x = 116
x = 58
--------------
y = 97 - 58
y = 39
To find the ages of two friends based on the sum and difference of their ages.
Explanation:James and Tyson are two friends whose ages sum up to 97 and have a difference of 19. To find their ages, we can set up a system of equations:
Let's denote James' age as x and Tyson's age as y.We have the equations: x + y = 97 and x - y = 19.Solving these equations simultaneously gives x = 58 and y = 39.Therefore, James is 58 years old, and Tyson is 39 years old.

Find the perimeter of the triangle below. Then, explain the steps you used to find the perimeter
The perimeter of the triangle = 60 cm
Solution:
The given triangle is a right triangle.
Base of the triangle = 15 cm
Hypotenuse = 25 cm
Let the unknown side of the triangle be x.
Using Pythagoras theorem,
In right triangle, square of the hypotenuse is equal to the sum of the squares of the other two sides.
[tex]x^2+15^2=25^2[/tex]
[tex]x^2+225=625[/tex]
Subtract 225 from both sides,
[tex]x^2=400[/tex]
Taking square root on both sides, we get
x = 20
The unknown side of the triangle is 20 cm.
The perimeter of the triangle = Sum of the sides of the triangle
= 15 cm + 25 cm + 20 cm
= 60 cm
The perimeter of the triangle = 60 cm
On 1st January 2016 Li bought a boat for $170000
The value of the boat depreciates by 8% per year.
Work out the value of the boat on 1st January 2019
Give your answer correct to the nearest dollar.
After a depreciation of 8% per year for 3 years, the value of Li's boat depreciates to approximately $136258, according to the formula for calculating the value of an asset after a certain number of years of depreciation.
Explanation:The value of an asset after a certain number of years, taking into account annual depreciation, can be calculated using the formula: Preliminary Value x ((100 - Depreciation Rate) / 100) ^ Years Of Depreciation.
Given that the initial value of Li's boat was $170,000 and it depreciated by 8% each year, we can substitute these values into the formula to find the value of the boat on 1st January 2019 (after 3 years).
So, the boat's value would be: $170,000 x ((100 - 8) / 100) ^ 3. This simplifies to $170,000 x (0.92) ^ 3, yielding a final value of approximately $136258

Each lapel on a suit jacket is in the shape of a triangle.the three angles of each triangle measure 47 , 68 and 65. classify the triangle by its angles
The type of triangle is acute angled triangle.
Solution:
Let us first define the type of triangles based on angles.
If all angles of a triangle are less than 90°, then it is acute angled triangle.
If any one angle of a triangle is exactly 90°, then it is right angled triangle.
If any one angle of a triangle is more than 90°, then it is obtuse angled triangle.
Given angles of a triangle:
47°, 68° and 65°
Here all the three angles are less than 90°.
Hence it is a acute angled triangle.

Two sides of a triangle measure 10 cm and 18 cm. Which could be the measure of the third side of the triangle?
6 cm
8 cm
12 cm
30 cm
Answer:
12cm is the answer as the two lowest sides must be more in size than its longest side. 10+12=22
Step-by-step explanation:
Final answer:
The possible length of the third side of a triangle with two sides measuring 10 cm and 18 cm, according to the Triangle Inequality Theorem, must be more than 8 cm and less than 28 cm. Therefore, the valid measures among the given options are 8 cm and 12 cm.
Explanation:
The question concerns determining the possible length of the third side of a triangle when the lengths of the other two sides are given. The Triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. Using this theorem, if we have sides measuring 10 cm and 18 cm, the possible lengths of the third side could be more than the difference of the two given sides and less than their sum. Therefore, the third side must be greater than 8 cm and less than 28 cm.
Among the given options, 6 cm is not a possible length because it is less than 8 cm and would not satisfy the Triangle Inequality Theorem. Similarly, 30 cm is not a possible length because it exceeds the sum of the two given sides. However, both 12 cm and 8 cm are possible lengths for the third side since both values are within the allowable range.

If the r-value, or correlation coefficient, of a data set is 0.934, what is the
coefficient of determination to three decimal places?
ASAP NEED ANSWERS :) PLEASEEEEEEEE
Answer:
C I think.
Step-by-step explanation:
=============================================
Why this is the answer:
The rectangle has 3 circles packed inside it each with the same radius r. The diameter of each circle is 2r, so 3 of them result in a total rectangle length of 3*2r = 6r.
While one circle has a circumference of C = 2*pi*r = 2*3.14*r = 6.28r
Comparing 6.28r and 6r, we see that 6.28r is larger than 6r
6.28r > 6r
6.28 > 6 ... dividing both sides by r (the inequality sign doesn't change because r > 0)
This is true for any value of r.
