Answer: -20
percent error= amount of error/actual value * 100
amount of error= 100-125= -25
percent error = -25/125 *100
percent error= -20
The percent error of Hannah's estimate will be 20%.
Hannah estimates the ribbon's length to be 100 cm. The ribbon's real length is 125 cm.
How to calculate the percent error?To find the percent error of Hannah's estimate, we need to first calculate the difference between the estimated value and the actual value.
In this case, the difference is 125 cm - 100 cm = 25 cm.
Now we can divide the difference by the actual value and multiply by 100% to find the percent error.
As per the given question, the percent error is :
⇒ (25 cm / 125 cm) x 100%
⇒ 0.2 x 100%
⇒ 20%.
Therefore, the percent error of Hannah's estimate will be 20%.

Step-by-step explanation:
Shawna needs to buy apples to bake pies for the fair. She needs 13 pounds of apples. At one market, she
finds apples selling for $1.89 a pound. At another market she finds a 15-pound bag of apples for $26.99.
Which market has the better deal?
Answer:
The market that sells a 15-pound bag of apples for $26.99.
Step-by-step explanation:
because in the first market 1 pound of apple equals $1.89, we must multiply it times 15 if we need 15 pounds which are $28.35 ($1.89 x 15), but in the second market, 15 pound of apples equals $26.99, compared to the first market the second market has a lesser price so we get to save $1.36 if we buy in the second market rather than buying apples in the first market.

A baker uses 70 grams of sea salt for each batch of bread. Sea salt comes in a 28-kilogram package or a 1,500-gram package. Which size package should the baker buy so that no sea salt is left after all of the batches are made? Explain.
Select the correct choice below and fill in the answer box(es) to complete your choice.
A.
Since 1,500 grams can be divided evenly into nothing batches of bread, 70 divides evenly into 1,500. So, the baker should choose the 1,500-gram package.
B.
A 28-kilogram package contains nothing grams of sea salt, which can be divided evenly into nothing batches of bread. So, the baker should choose the 28-kilogram package.

Part A: A graph passes through the points (0, 2), (2, 6), and (3, 12). Does this graph represent a linear function or a non-linear function? Explain your answer in words.
Part B: Write one example of a linear function and one example of a non-linear function. (Use x and y as the variables)
Part A: No. The line would have to be straight in order for the graph to be linear.
Part B:
Linear: y=2x-4.
Nonlinear: y=x^2-6.

The correct match of inequalities are 5 - 3x ≥ 11 → 4
1 + 3x ≥ -5 → 3
5x + 7 ≥ 17 → 1
2x + 1 ≤ 3 → 2
What are inequalities?A relationship between two expressions or values that are not equal to each other is called 'inequality'.
Given are four inequalities with four number lines,
5x + 7 ≥ 17: Number line 1
2x + 1 ≤ 3: Number line 2
1 + 3x ≥ -5: Number line 3
5 - 3x ≥ 11: Number line 4
Hence, The correct match of inequalities are 5 - 3x ≥ 11 → 4
1 + 3x ≥ -5 → 3
5x + 7 ≥ 17 → 1
2x + 1 ≤ 3 → 2

Three salesmen work for the same company, selling the same product. And, although they are all paid on a weekly basis, each salesman earns his paycheck differently. Salesman A works strictly on commission. He earns $65 per sale, with a maximum weekly commission of $1,300. Salesman B earns a weekly base salary of $300, plus a commission of $40 per sale. There are no limits on the amount of commission he can earn. Salesman C does not earn any commission. His weekly salary is $900.
Suppose Salesmen A and B have the same number of sales and earn the same amount in Week 4 of this month. How many sales must they both have had?
sales
Answer: 12
Explanation: x will be the number of sales the sales man had. so this is the equation 65x = 40 +300
65x -40x = 25x
25x = 300 then divide by 25
25 25
x = 12
