Answer:
7.4 % is percent error
Step-by-step explanation:
https://brainly.com/question/21689164
The percent of error is 7.4%. The correct option is B.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given:
Estimated value: 231
Actual value: 215
To find the percentage:
First, the value,
= 231 - 215
= 16
Now,
let n be the percentage.
So,
16 = n x 215/100
n = 1600/215
n = 7.4%
Therefore, 7.4% is the error.

Mark Me Brainliest Please.A rectangular garden has a length that is 3 feet longer than its width. Let w represent the width of the garden in feet. The entire garden is surrounded by a 2-foot-wide cement walkway.
Answer:
Step-by-step explanation:
From the question, we're told that the length of the garden is 3 feet longer than its width. Mathematically, we would have
l = w + 3, where
l = length of the garden
w = width of the garden
Again we're told that this same garden has a walkway of about 2 foot wide. Mathematically we would have that as
W(w) = 2, where
W(w) = width of the garden.
That's all the parameters given in the question

For camping mrjohn son needs 12 1-2 feet of rope to tie the logs that he has to cut for the campfire and 9 3-4 feet of the rope for the clothesline what is the total length of rope he needs for the camping trip
Answer:
Mr. John will need not less than [tex]22\frac{1}{4}[/tex] feet of rope for the camping trip
Step-by-step explanation:
To get the total length of rope Mr John needs for the camping trip, we can simply add up the length of rope he needs to tie the logs to the length of rope he needs for the clothesline.
Length of rope he needs to tie the logs = [tex]12\frac{1}{2}[/tex]
Length of rope he needs for the clothesline = [tex]9 \frac{3}{4}[/tex]
to sum this up, we, first of all, add up the whole numbers
12 + 9 = 21.
We then keep this aside then add up the fractions
[tex]\frac{1}{2} +\frac{3}{4} =\frac{2 +3}{4} = 5/4 = 1\frac{1}{4}[/tex]
We then add this to our whole numbers
[tex]21 + 1\frac{1}{4} =22 \frac{1}{4}[/tex]
Mr. John will need not less than [tex]22\frac{1}{4}[/tex] feet of rope for the camping trip

Find the sum of the first 33 terms of the following series, to the nearest
integer.
2,8, 14, ...
Answer:
3234
Step-by-step explanation:
The series is arithmetic with a common difference = d = 6
First we need to find the 33rd term. Use the formula [tex]a_{n} = a_{1} + (n - 1)d[/tex] where n = 33 and [tex]a_{1} = 2[/tex]
[tex]a_{33} = 2 + (33 - 1)6 = 2 + 32(6) = 194[/tex]
Now the formula for the sum of an arithmetic series is [tex]S_{n} = \frac{n(a_{1} + a_{n} )}{2}[/tex]
So, [tex]S_{33} = \frac{33(2 + 194)}{2}[/tex]
= [tex]\frac{33(196)}{2}[/tex]
= 3234

Standard to Slope Intercept Form
Put the following equation of a line into slope-intercept form, simplifying all fractions.
2x+8y=24
Answer:
y = - [tex]\frac{1}{4}[/tex] x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
2x + 8y = 24 ( subtract 2x from both sides )
8y = - 2x + 24 ( divide all terms by 8 )
y = - [tex]\frac{1}{4}[/tex] x + 3 ← in slope- intercept form

Renee bought 7 potatoes at the supermarket. The shortest diameter of each, in centimeters, is shown below
Answer:
2, 3, 4
Step-by-step explanation:
Renee bought 7 potatoes at the supermarket. The shortest diameter of each,
in centimeters, is shown below.
2, 3, 4, 4, 6, 6, 7
After Renee used one potato to make dinner, the median diameter of the remaining potatoes was 5 centimeters. Which of these could be the diameter, in centimeters, of the potato Reneetsed?
Solution:
The median of a group of numbers is the middle number when the group of numbers are arranged in a sorted manner, either ascending or descending.
The median of an even group of numbers, is gotten by taken the average of the two innermost numbers.
Given that the diameter of the potato as:
2, 3, 4, 4, 6, 6, 7
Given that after removing one potato, the median of the remaining potatoes was 5 centimeters.
After removing one potato, the remaining would just be 6. 6 is an even number, hence the median would be the average of the 2 middle numbers.
To get 5 cm, it has to be the average between 4 and 6. This is only possible when a potato of diameter 2,3 or 4 is removed.
If potato with diameter 2 is removed, the remaining is 3, 4, 4, 6, 6, 7.
Median = (4 + 6) / 2 = 5
If potato with diameter 3 is removed, the remaining is 2, 4, 4, 6, 6, 7.
Median = (4 + 6) / 2 = 5
If potato with diameter 4 is removed, the remaining is 2, 3, 4, 6, 6, 7.
Median = (4 + 6) / 2 = 5

Solve for c:
c + (-20) = -12
Answer:
8
Step-by-step explanation:
Isolate and solve for C
[tex]c + (-20) = -12\\c - 20 = -12\\c = -12+20\\c = 8[/tex]
Answer:
C = 8
Step-by-step explanation:
By reversing the equation, you can get the result.
-12 + 20 = ?
-12 + 20 = 8
Proofcheck:
8 + (-20) = ?
8 + (-20) = -12

In ∆ABC,
∠A = 60°∠B = 60°BC = 12 units∠BDC = 90°To Find :Area of ∆ABC = ?Solution :As, we have :
∠A = 60°∠B = 60°So, By angle sum property of triangle :
∠A + ∠B + ∠C = 180°
[tex] \tt : \implies 60\degree + 60\degree + \angle C = 180\degree[/tex]
[tex] \tt : \implies 120\degree + \angle C = 180\degree[/tex]
[tex] \tt : \implies \angle C = 180\degree - 120\degree[/tex]
[tex] \tt : \implies \angle C = 60\degree[/tex]
Now, we have :
∠A = 60°∠B = 60°∠C = 60°As, all angles are of same length, therefore it is a equilateral triangle.
We know that sides of equilateral triangle are equal.
[tex] \tt : \implies AB = BC = AC[/tex]
Now, we have BC = 12 units.
Hence, all sides are of 12 units.
Now, we know that area of equilateral triangle is :
[tex] \large \underline{\boxed{\bf{Area_{(equilateral \: triangle)} = \dfrac{\sqrt{3}}{4} side^{2}}}}[/tex]
[tex] \tt : \implies Area = \dfrac{\sqrt{3}}{4} \times (12 \: units)^{2}[/tex]
[tex] \tt : \implies Area = \dfrac{\sqrt{3}}{\cancel{4}} \times \cancel{144} \: units^{2}[/tex]
[tex] \tt : \implies Area = \sqrt{3} \times 36 \: units^{2}[/tex]
[tex] \tt : \implies Area = 36\sqrt{3} units^{2}[/tex]
So, Area of given triangle is 36√3 units².

step 1. an example of difference of squares (dos) is (x + y)(x - y) = x^2 - y^2.
step 2. dos must have only 2 square rootable terms and a "-" between them.
step 3. 196x^2 - 121y^2 = (14x + 11y)(14x - 11y) works!
step 4. 5x^2 - 245 = 5(x^2 - 49) = 5(x + 7)(x - 7) works!
step 5. 27w^5 - 75w = 3w(9w^4 - 25) = 3w(3w^2 + 5)(3w^2 - 5) works!
step 6. x^4 - 100y^2 = (x^2 - 10y)(x^2 + 10y) works!
