percent error
[tex]\delta = \left| \frac{v_A - v_E}{v_E} \right| \cdot 100\%[/tex]
δ= percent error
vA =actual value observed
vE =expected value
δ=25-28/28*100
δ=-3/28*100
δ=0.107*100
δ=10.7%
The percent error is 10.7%

Step-by-step explanation:
#11
In the given figure
∵ BA // CF
∵ BC is a transversal
∵ ∠1 and ∠BCF are interior alternate angles
∵ The interior alternate angles are equal in measures
∴ m∠1 = m∠BCF
∴ ∠1 ≅ ∠BCF ⇒ (1)
∵ BC // ED
∵ CF is a transversal
∵ ∠BCF and ∠2 are corresponding angles
∵ The corresponding angles are equal in measures
∴ m∠BCF = m∠2
∴ ∠BCF ≅ ∠2 ⇒ (2)
→ From (1) and (2)
∵ ∠1 and ∠2 are congruent to ∠BCF
∴ ∠1 and ∠2 are congruent
∴ ∠1 ≅ ∠2 ⇒ proved

In triangle QPS and triangle QSR,
PQ = RQ [Given]
Angle PQS = Angle SQR [ a = a]
QS = QS [Common]
So, triangle QPS is congruent to triangle QSR by SAS (Side-Angle-Side) congruence rule.
So,
PS = SR [By CPCT (Corresponding parts of Congruent triangles) ]

Addisonand Nolan are reading the same book. At the beginning of the month, Addison was on page 7 and Nolan was on page 47. Addison will read 11 pages per day and Nolan will read 6 pages per day. Let A represent the page of the book that Addison is on at the end of t days into the month, and let N represent the page of the book that Nolan is on at the end of t days into the month. Write an equation for each situation, in terms of t, and determine whether Addison or Nolan is farther along in the book after 4 days.
Answer:
A = 51 pages
N = 71 pages
Nolan will be 20 pages farther along in the book than Addison after 4 days.
Step-by-step explanation:
for Addison if you multiply 11 by 4 you get 44 then you add 7 you get 51
For Nolan if you multiply 6 by 4 you get 24 then you add 47 and you final answer is 71

Whitney deposits $9,000 for two years. She compares two different banks. State Banks will pay her 4.1% interest, compounded monthly. Kings Savings will pay her 4.01% interest, compounded continuously.
Answer:
1)state bank
2)$16.21
Step-by-step explanation:
CHECK THE COMPLETE QUESTION BELOW
Whitney deposits $9,000 for two years. She compares two different banks. State Banks will pay her 4.1% interest, compounded monthly. Kings Savings will pay her 4.01% interest, compounded continuously.Which bank pays higher interest? How much higher?
The Amount in the formula for compound interest is
A= P(1+r)^2
P = principal amount,
r = rate per periods,
t = number of periods,
To know the interest she got from the State bank, we say
P = $ 9000, r = 4.1% = 0.041, t = 2 years,
A= 9000(1+0.041)^2
A= 9000(1.041)^2
= 9767.74
Then interest earned = A - P
= 9767.74 - 9000
= $ 767.74
To know the interest she got from the State bank, we say
P = $ 9000, r = 4.01% = 0.0401, t = 2 years,
A= 9000(1+0.0401)^2
A= 9000(1.0401)^2
= 9751.53
Then interest earned = A - P
= 9767.74 - 9000
= $ 751.53
The difference between the two interest is ($ 767.74 - $ 751.53)
=$16.21
Hence state bank will have $16.21 higher interest

Answer:
[tex]\frac{5}{-1.6}<-3\frac{3}{10}-(-\frac{7}{20})<5\frac{6}{15}+(-2\frac{4}{5})<-4.5\times -2.3[/tex]
Step-by-step explanation:
We will solve the given expressions and find the answer in decimals.
1). [tex]5\frac{6}{15}+(-2\frac{4}{5})[/tex] = [tex]5\frac{2}{5}-2\frac{4}{5}[/tex]
= 5.4 - 2.8
= 2.6
2). [tex]-3\frac{3}{10}-(-\frac{7}{20})=-3\frac{3}{10}+\frac{7}{20}[/tex]
= -3.3 + 0.35
= -2.95
3). [tex]\frac{5}{-1.6}=-\frac{5}{1.6}[/tex]
= -3.125
4). (-4.5) × (-2.3) = 10.35
Solution of the expressions in the increasing order will be,
-3.125 < -2.95 < 2.6 < 10.35
[tex]\frac{5}{-1.6}<-3\frac{3}{10}-(-\frac{7}{20})<5\frac{6}{15}+(-2\frac{4}{5})<-4.5\times -2.3[/tex]

find the whole number quotient and remainder of 201 divided by 12
Answer:192 r 9
Step-by-step explanation:
The division of 210 by 12 gives quotient = 17 and remainder = 6.
What is Division?One of the four fundamental mathematical operations, along with addition, subtraction, and multiplication, is division. Division is the process of dividing a larger group into smaller groups so that each group contains an equal number of things. It is a mathematical operation used for equal distribution and equal grouping.
We have to divide 210 by 12.
So, the division is
12 | 210 | 17

The perimeter of a parallelogram must be no less than 40 feet. The length of the rectangle is 6 feet. What are the
possible measurements of the width?
a. Write an inequality to represent this problem. Use w to represent the width of the parallelogram. (Hint: The formula
for finding the perimeter of a parallelogram is P = 21 + 2 w.
b. What is the smallest possible measurement of the width? Justify your answer by showing all your work.
Step-by-step explanation:
If you know that your perimeter must be no less than 40 feet, you can say that P >= 40 ft. Since P is given by P=2l+2w, you can combine the two equations into a single inequality:
2l+2w >= 40
If the length is given by 6 feet, then you can further simplify the inequality to be
12+2w >= 40 --> w >=14
Here is a riddle:
The sum of two numbers is less than 10.
If we subtract the second number from the first, the difference is greater than 3.
Write a system of inequalities that represents this situation. Let f represent the first number and s represent the second number.
Answer:
The system of inequalities that represents this situation will be:
[tex]f + s < 10[/tex]
[tex]f - s > 3[/tex]
Step-by-step explanation:
Let 'f' represent the first numberLet 's' represent the second number.Given that the sum of the two numbers is less than 10. As 'less than' can be represented by '<'.
so the inequality would be: f + s < 10Given that If we subtract the second number from the first, the difference is greater than 3. As 'greater than' can be represented by '>'.
so the inequality would be: f-s > 3Thus, the system of inequalities that represents this situation will be:
[tex]f + s < 10[/tex]
[tex]f - s > 3[/tex]

[tex]2.15f+4.6n\leq 150[/tex]
Step-by-step explanation:
She has a budget of $150, which means that she can spend no more than that amount. Therefore, use the less than or equal to symbol: ≤
Each folder is $2.15, so you are going to multiply: 2.15 × f
Each notebook is $4.60, so you will multiply: 4.6 × n
You want to know how many notebooks and folders you can buy for $150, so add the notebooks and folders.
Make the equation:

The equation that represents the canned goods order is
24x + 4y = 384, where x = number of minutes spent
producing fruit cans, and y = number of minutes
producing vegetable cans.
If the vegetable assembly line runs for 3 minutes, how
many minutes would the fruit assembly line need to run to
complete the order of 384 cans? Explain
Answer:
8 minutes.
Step-by-step explanation:
24x + 64y = 384, that represents the canned goods order .
where x = number of minutes spent producing fruit cans,
and y = number of minutes producing vegetable cans.
If the vegetable assembly line runs for 3 minutes, then put y=3 in equation we get
Therefore, the fruit assembly line need to run to complete the order of 384 cans in 18 minutes.
Answer:
Substitute 3 into the equation for y. Solve for x and find that x = 8. So if cans of vegetables are processed for 3 minutes, fruit needs to be processed for 8 minutes to complete the 384-can order.
