The percentage error in the situation, where Estimated value 1081
and Actual value 1150 is, 6%
What is the percentage?The percentage is a mathematical term, which means a number or a ratio which is represented in fractions of 100. We use the '%' symbol to represent the percentage.
Formula for percentage;
Percentage = (present quantity/whole quantity)×100
Given that,
Estimated value: 1081
Actual value: 1150
Percentage error = [Actual value - Estimated value]/Actual value×100
= [1150 - 1081]/1150×100
= 6
Hence, the percentage error is 6%

Answer:
300 [tex]in^{2}[/tex]
Step-by-step explanation:
First, calculate the area of the rectangle. The height and width are 10 and 20, so the area is 200 [tex]in^{2}[/tex].
For the triangle, we know the base length is 10 inches. But for the height, you add the 10 inches that happens to be part of the rectangle and another 10 inches, which is shown to the left of the top of the triangle, making the height 20 inches. Following the formula for the area of a triangle, [tex]\frac{bh}{2}[/tex], you would get 100 [tex]in^{2}[/tex].
To get the total area of the whole figure, add 200 and 100, which will give you 300 [tex]in^{2}[/tex]
also math makes me sad sometimes too so that's very relatable

-x+4y=24 and -2x+y=-8 as an ordered pair
Answer: (8,8)
Step-by-step explanation:
First you need to get a x or y by itself.
I choosed to get y by itself since it would be faster.
-2x + y = -8 (first get -2x to the other side so add 2x)
y = -8 + 2x (then you want to insert that to the other equation)
-x + 4( -8 +2x) = 24 -> -x -32 + 8x = 24 -> 7x -32 = 24
(add 32 to the other side)
7x = 56 (divide 7 to 56 to get x) x = 8
now insert into the other equation
-2( 8 ) + y = -8 -> -16 + y = -8 ( move -16 to the other side, so add 16)
then you get your answer, y= 8

During the Industrial Revolution, explain what caused the population of light-colored peppered moths to decrease and the population of dark-colored peppered moths to increase over time. Be sure to include how the ability to survive and reproduce impacts the process of natural selection.
Thank you lot to whoever tells me the right answer. i've been struggling a lot on this and have been for days on the same but can't find the right answer..
Thank you and pls don't do it for point pls :(
Also i'll give brainliest!
Step-by-step explanation:
This lead to the rapid decrease in the light-colored moths. ... Since birds would find and eat the light-bodied moths, dark-coloured moths increased as a result of natural selection. Thus, these moths with a favorable adaptation to the change in the environment were selected and they reproduced new offspring.

Answer:
3≥x or 3>x *depends on what you are currently learning in class
Step-by-step explanation:
3 is less than x
Tell me if this works!! :)
Explanation:
If the arrow is going to the direction less than 3. 3 is going to be less. x is found greater than 3 so that's why the inequality sign will have open wide to 3. This is signifying that x is larger and will "eat" 3.
≥ is used to plot less than or equal to signs.
A closed dot means greater than/less than or equal too.
A open dot means greater than or less than.

Answer:
3x + 7
Step-by-step explanation:
I am not 100% sure if this is right but I did try and thats what counts. The reason I think this is because since we don't know what x is we cant add or subtract it so instead we subtract it from 6 and put 12 and 5 together. Hope this helps
add or subtract the polynomials
(7x + 11y) - (5x + 6y)
(13x + 12y) - (6x + 2y)
(8x + 8y) - (4x - 2y)
Answer:
7xy + 6y + 6xy is a polynomial who’s like terms are 7xy and 6xy. Therefore, this polynomial can be simplified by combining like terms as 7xy +6xy +6y = 13xy + y. When combining like terms, we only add or subtract the coefficients of the identical variables.
On the other hand, unlike terms are terms which are not identical in terms of either variables or exponents.
For example, an expression 4x + 9y2, contain unlike terms because variable x and y are different and are not raised to the same power.
Answer:
1.
7x+11y-(5x+6y)
7x+11y-5x-6y
2x+5y
2.
13x+12y-(6x+2y)
13x+12y-6x-2y
7x+10y
3.
8x+8y-(4x-2y)
8x+8y-4x+8y
4x+16y

The probability of winning money on a particular ''scratch and win'' ticket is said to be 3 out of 10. If mrs. curcio buys 25 tickets to hand out to her students, how many of those would you predict to be ''winners''?
Answer:
8/25
Step-by-step explanation:
The total amount of tickets is 25 so divide 10 from 25 to figure out what you multiply by to get 25
--> 25/10 = 2.5
now multiply 2.5 x 3 to have a numerator which would be your probability of winners out of 25 tickets
--> 2.5 x 3 = 7.5 (round to the nearest whole number)
7.5 rounded to the nearest whole number --> 8
so you get 8 out of 25 = 8/25
