You estimate that the length of your
classroom is 20 feet. The actual length is 25
feet. Find the percent of error.
Answer:
The percent error is 20%.
Step-by-step explanation:
The general formula is to subtract the actual value from the estimated value, take the absolute value of the difference, divide that answer by the actual value, then multiply it by 100.
So, 20 (estimated) minus 25 (actual) is -5. The absolute value of -5 would be 5, since absolute value is always positive. Divide 5 by the actual value, 25, and you get 0.2. Multiply 0.2 by 100 to get a percent value, and the answer will amount to 20%. Hope this helps.

A bakery produces 2 batches of bread with 80 loaves in each batch. It sold 30 loafs each hour. How many loaves of bread were sold in 4 hours? How many loaves of bread were left to sell?
Answer:
Total number of loaves of bread sold in [tex]4[/tex] hours is [tex]120[/tex] and [tex]40[/tex] loaves of bread will remain unsold.
Step-by-step explanation:
Given: A bakery produces [tex]2[/tex] batches of bread with [tex]80[/tex] loaves in each batch.
It sold [tex]30[/tex] loafs each hour.
To find: How many loaves of bread were sold in [tex]4[/tex] hours? How many loaves of bread were left to sell?
Solution:
Total number of loaves of bread produced [tex]=2 \times 80=160[/tex].
Number of loafs sold each each hour [tex]=30[/tex].
So, number of loafs sold in [tex]4[/tex] hours[tex]=4 \times 30=120[/tex].
Therefore, number of loaves of bread that were remain unsold [tex]=160-120=40[/tex]
Hence, total number of loaves of bread sold in [tex]4[/tex] hours is [tex]120[/tex] and [tex]40[/tex] loaves of bread will remain unsold.

A contractor purchases 5 dozen pairs of padded work gloves for 71.40 he incorrectly calculates the unit price as 14.28 per Pair for the expense report . What is the correct unit price ? What is the error?
Answer:
0%
Step-by-step explanation:
Step one:
given data
A contractor purchases 5 dozen pairs of padded work gloves for $71.40
the unit price will be
total number of gloves
5 pairs
unit cost per glove
=71.40/5
=$14.28 per glove
The estimated cost per pair is
$14.28 per pair
The error is
%Error= real price -estimated /estimated*100
%Error= 14.28-14.28/14.28*100
%Error= 0.0*100
%Error= 0%

2/3x-7=11
Pls help
Answer:
x = 27
Step-by-step explanation:
Given
[tex]\frac{2}{3}[/tex] x - 7 = 11 ( multiply through by 3 to clear the fraction )
2x - 21 = 33 ( add 21 to both sides )
2x = 54 ( divide both sides by 2 )
x = 27
The value of x in the equation 2/3x-7 =1 is 12.
The given equation is 2/3x-7 =1.
x is the variable in the equation.
Minus is the operator.
To solve for x add 7 on both sides:
2/3x-7+7=1+7
2/3x=8
Multiply both sides by 3/2.
x=3/2×8
x=12
Hence, the value of x in the equation is 12.

How can you apply the information you learn in your math courses in your daily life? How will it benefit you in the future?
Math can help you if you ever wanna build a desk in the future;)
Maths can be used in the day-to-day shopping at home groceries and vegetables etc.
What is maths?Numbers, formulae, and related structures, shapes, and the spaces in which they are contained, as well as quantities and their variations, are all covered in the field of mathematics.
An example of daily life is if you are going to the market to purchase fruits the cost of 1 kg of apple is 200rs but you want to buy 30 rs apple only. Then the amount in kg for the 30rs apple will be calculated by using maths.
200rs apple = 1 kg
1 rs apple = 1 / 200 kg
30 rs apple = ( 1 x 30 ) / 200
30 rs apple = 0.15 kg or 150 grams
In this way, you will get the exact amount of apple for 30 rupees amount by using mathematics
Therefore, maths can be used in the day-to-day shopping at home groceries and vegetables, etc.
