Given:
18% increase followed by a 13% decrease.
To find:
The single percentage equivalent to a 18% increase followed by a 13% decrease.
Solution:
Let a number be 100.
If it is increased by 18% then the number becomes
[tex]Number=100+\dfrac{18}{100}\times 100[/tex]
[tex]=100+18[/tex]
[tex]=118[/tex]
Then, it is decreased by 13%.
[tex]Number=118-\dfrac{13}{100}\times 118[/tex]
[tex]=118-15.34[/tex]
[tex]=102.66[/tex]
New number is 102.66.
Now, the percentage change is
[tex]\%\text{ Change}=\dfrac{\text{New number - Initial number}}{\text{Initial number}}\times 100[/tex]
[tex]\%\text{ Change}=\dfrac{102.66-100}{100}\times 100[/tex]
[tex]\%\text{ Change}=\dfrac{2.66}{100}\times 100[/tex]
[tex]\%\text{ Change}=2.66\%[/tex]
Therefore, the Single percentage change is 2.66%.

Answer:
Their beliefs over who should have succeeded the Prophet Muhammad is the key theological difference between the two. Sunnis also have a less elaborate religious hierarchy than Shiites have, and the two sects' interpretation of Islam's schools of law is different
Step-by-step explanation:
hope this helps :)
Answer:
Shia people think that imam ali is the 1st khalifa or should be the first, because the profet Muhammed said that " I leave in you the two heavens, the Book of God, and my family" and after that the prophet rasied Imam Ali hand and said: " Whoever believe that i was the prophet should believe that Ali is the person in charge after I go meet Allah.
and so shia thinks that he is the person in charge after the prophet Muhammed.
Sunni people say that omar and abo baker are the people in charge. wich is so disrespecful to the prophet, because he said that Ali is incharge of the muslims by-step explanation:
the difference are shia believes that Imam Ali is the first khalifa and the sons of ali are the once incharge after him.

What is the answer for "The points (4,r) and (8,-11) lie on a line with slope -3. Find the missing coordinate r."?
Answer:
r = 1Step-by-step explanation:
Use the slope formula:
m = (y₂ - y₁)/(x₂ - x₁)m = -3, x₁ = 4, y₁ = r, x₂ = 8, y₂ = -11Substitute values and solve for r:
-3 = (-11 - r)/(8 - 4)-3 = -(11 + r)/411 + r = 12r = 12 - 11r = 1Answer:
The answer to your question is R=1

4 - 2 × 8 + (6 × 2) × 4 + 3²
= 4 - (2 × 8) + (6 × 2) × 4 + 3²
= 4 - 16 + 12 × 4 + 9
= (4 - 16) + (12 × 4) + 9
= -12 + 48 + 9

Express the number of months in the year that are only 4 letters as a fraction in the simplest form, decimal rounded to the nearest thousandth and whole percent.
Answer:
There are only 2 months out of the 12 that have 4 letters in their name so it would be represented as 2/12, the numerator representing those 2 months and the numerator representing the 12 months in 1 year. 2/12 in its simplest form would be 1/6 because if you use the big one to simplify 2/12 and divided it by 2/2 you get 1/6. 1/6 as a decimal is 0.16 wich is 16% as a percent.
Hope this helps :)
What is the image of (8,-6) after a reflection over the line y = x?
Answer:
Step-by-step explanation:
Interchange x and y: (-6, 8) is the image of (8, -6) after a reflection over y = x.
The image of (8,-6) after a reflection over the line y=x is (-6, 8).
The given coordinate point is (8, -6).
What is a reflection over the line y=x?Reflect over the y = x, when you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed).
The image of (8,-6) after a reflection over the line y=x is
Reflecting in the line y = x interchanges the x and y coordinates. So, the image of (8, -6) is (-6, 8).
Therefore, the image of (8,-6) after a reflection over the line y=x is (-6, 8).

Spiral Review Gretchen is delivering boxes of cookies to her neighbors. Her wagon itself weighs 12 pounds when empty and will hold up to 9 boxes.
If each box of cookies weighs 1 pound, what is the range of the total weight of her wagon while she is delivering cookies?
Enter the correct answers in the boxes.

Answer:
0-108
Step-by-step explanation:
I have the same assignment and got it while working on it
you have to say from either 0 or 12 pounds to 108 as you have to multiply 12 x 9.
The range of the total weight of her wagon while she is delivering cookies is 12 pounds to 21 pounds.
What is addition?Combining objects and counting them as one big group is done through addition. In arithmetic, addition is the process of adding two or more integers together. Addends are the numbers that are added, and the sum refers to the outcome of the operation.
Given:
Spiral Review Gretchen is delivering boxes of cookies to her neighbors. Her wagon itself weighs 12 pounds when empty and will hold up to 9 boxes.
Each box of cookies weighs 1 pound.
Weight of 9 boxes = 9 pounds.
So, the range,
= 12 pounds to 12 + 9 pounds
= 12 pounds to 21 pounds.
Therefore, the range is 12 pounds to 21 pounds.
