The number of batches you can make if you use all the sugar is 12.61 batches.
The cost of sugar used per batch is $0.28.
How many batches can you make if you use all the sugar?A 4-pound bag of sugar = 454 one-teaspoon
Sugar used for a batch of muffins = ¾ cup
If 1 cup = 48 teaspoons
3/4 cup = 3/4 × 48
= 36 teaspoons
Number of batches to make = 454 one-teaspoon / 36 teaspoons
= 12.61 batches
Cost of sugar teaspoons= 3.49/454
= $0.007687224669603 per teaspoon
Cost of sugar per batch = 0.007687224669603 × 36
= $0.276740088105726 per batch
Hence, the cost of sugar used per batch is approximately $0.28

A 4-pound bag of sugar contains 454 one-teaspoon servings and costs $3.49. A batch of muffins uses ¾ cup of sugar. How many batches can you make if you use all the sugar? What is the cost of sugar for each batch? (1 cup = 48 teaspoons)
To find out how many batches of muffins can be made and the cost per batch, convert the total servings of sugar to cups, then divide by the amount of sugar used per batch, and finally, divide the total cost by the number of batches. which results in approximately $0.29 per batch.
The subject of this question is Mathematics, and it appears to be at the High School level due to the application of ratios, conversions, and basic algebraic skills to solve real-world problems.
Calculating Batches of Muffins from a Sugar Bag
Firstly, we determine the total amount of sugar in the bag in terms of cups. Since 1 teaspoon is equivalent to 4 grams of sugar, and we have 454 servings, we multiply 454 by 4g to get 1816g of sugar in total. To convert grams to cups (given 1 cup of sugar is 200g), we divide 1816g by 200g/cup, which gives us 9.08 cups.
Since a batch of muffins uses 3/4 cup of sugar, we divide the total cups of sugar by 3/4 to find the number of batches. 9.08 cups divided by 3/4 cups per batch results in approximately 12.1 batches; however, since you can't make a partial batch with the remaining sugar, it is safe to say you can make 12 full batches. To find the cost per batch, divide the total cost of the bag ($3.49) by the number of batches (12), which results in approximately $0.29 per batch.

A teacher wants to calculate a class average on the last test. One student made a significantly lower score than the rest of the class because he failed to follow instructions. Which measure of center would be best for the teacher to use to get an accurate idea on how well the class as a whole performed on the last test?
A. mode
B. median
C. mean
D. range
Final answer:
The median is the best measure of center for the teacher to use to evaluate the overall performance of the class on a test when the data set includes an outlier.
Explanation:
The most appropriate measure of center for the teacher to use in this situation is the median. This is because the median is the best measurement when a data set contains outliers or extreme values that could significantly skew the mean. Since the dataset contains a student score that is significantly lower due to not following instructions, the median would provide a more accurate idea of how the class as a whole performed, as it is less affected by this outlier. On the other hand, the mode might not be as informative if most of the scores are unique, and the mean would be substantially affected by the low score. The range is a measure of spread, not center, and therefore not suitable for determining the average performance.
The school gym can hold no more than 650 people. The bleachers will seat 176 people. The PTA is setting up 25 rows of chairs for their meeting. At most, how many chairs can be in each row?
A) 18
B) 19
C) 26
D) 27
Answer:
A)18
Step-by-step explanation:
The number of chairs in the school gym can be represented by inequality 176 + 25c ≤ 650, where c represents the number of chairs in each row. When you solved for c, we find that c = 18.96. Since you cannot have a fraction of a chair, we know that the maximum number of chairs in each row must be 18.

Xavier worked 10 hours on Monday and 15 hours on Wednesday. His total pay was 280.00 what is his rate per hour
Xavier's rate per hour is $11.20.
What is unit rate?A unit rate means a rate for one of something. We write this as a ratio with a denominator of one. For example, if you ran 70 yards in 10 seconds, you ran on average 7 yards in 1 second. Both of the ratios, 70 yards in 10 seconds and 7 yards in 1 second, are rates, but the 7 yards in 1 second is a unit rate.
Given that, Xavier worked 10 hours on Monday and 15 hours on Wednesday. His total pay was 280.00
Number of hours worked on Monday = 10 hours
Number of hours worked on Tuesday = 15 hours
Total pay received by Xavier = $280
Total number of hours worked = (10 + 15) = 25 hours
Therefore, Rate per hour = 280/25 dollars per hour
Hence, Xavier's rate per hour is $11.20.

Shakira went bowling with her friends .she paid $3 to rent shoes and then $4.75 for each game of bowling.if she spent a total of $21 , then how many games did shakira bowl ?
Answer: Shakira bowled 4 games.
Step-by-step explanation:
Hi, the total cost for Shakira (21) is equal to the multiplication of the price of each game of bowl (4.75) and the number of games bowled (g), plus the cost of the shoes rental (3).
3 + 4.75 g = 21
Solving for g:
4.75 g = 21-3
4.75 g = 18
g= 18/4.75
g = 3.78 = 4 games (rounded)

An investment of $2,000 will double at a simple interest rate of 5% in 20 years.
An investment of $700 will double in 12 years at a simple interest rate of 6%.
this is the correct answer
Answer:
statement A, C, D, are true.
Step-by-step explanation:
We check all the statements by the rule of 72 to find which statement about doubling an investment are true.
Formula we use = [tex]\frac{72}{R}[/tex] R = Rate of interest
Statement A :
An investment of $5,000 will double in 6 years at an annual compound interest rate of 12%.
[tex]\frac{72}{12}[/tex] = 6 years
It will take 6 years to double the investment. This statement is true.
Statement B :
An investment of $1000 will double at an annual compound interest rate of 18% in 6 years.
[tex]\frac{72}{18}[/tex] = 4 years
It will take 4 years to double the investment. This statement is not true.
Statement C:
An investment of $350 will double in 9 years at a compound interest rate of 8%.
[tex]\frac{72}{8}[/tex] = 9 years
It will take 9 years to double the investment. This statement is true.
Statement D :
An investment of $2000 will double at a simple interest rate of 5% in 20 years.
Formula for Simple interest = (PRT)
I = (2000 × 0.05 × 20) = $2000
So the amount will be 4000 in 20 years. This statement is true.
Statement E :
An investment of $700 will double in 12 years at a simple interest rate of 6%
Interest = ( 700 × 0.06 × 12 ) = $504
Amount after 12 years 700 + 504 = $1204. This statement is not true.

Which graph represents the equation y=13x−4 ?
Answer: The correct option is graph (A).
Step-by-step explanation: We are given to select the graph that represents the following linear equation :
[tex]y=\dfrac{1}{3}x-4~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]
Comparing with the slope-intercept form y = mx + c of a straight line, we see that
the slope of the line (i) is [tex]m=\dfrac{1}{3},[/tex] and y-intercept, c = -4.
Also, we know that the slope of a line passing through the points (a, b) and (c, d) is given by
[tex]m=\dfrac{d-b}{c-a}.[/tex]
Graph (A) :
The points (0, -4) and (3, -3) lies on the line. So, its slope will be
[tex]m=\dfrac{-3-(-4)}{3-0}=\dfrac{1}{3},[/tex]
the point where the line crosses the y-axis is (0, -4).
That is, y-intercept, c = -4.
Since the slope and y-intercept of graph (A) is same as that of line (i), so this option is CORRECT.
Graph (B) :
The points (0, -2) and (3, -3) lies on the line. So, its slope will be
[tex]m=\dfrac{-3-(-2)}{3-0}=-\dfrac{1}{3},[/tex]
Since the slope of graph (B) is not same as that of line (i), so this option is NOT CORRECT.
Graph (C) :
The points (0, -4) and (-3, 3) lies on the line. So, its slope will be
[tex]m=\dfrac{3-(-4)}{-3-0}=-\dfrac{7}{3},[/tex]
Since the slope of graph (C) is not same as that of line (i), so this option is NOT CORRECT.
Graph (D) :
The points (-4, 0) and (-3, 3) lies on the line. So, its slope will be
[tex]m=\dfrac{3-0}{-3-(-4)}=\dfrac{3}{1}=3,[/tex]
Since the slope of graph (B) is not same as that of line (i), so this option is NOT CORRECT.
Thus, graph (A) is the correct option.

A movie theater charges $10.50 per ticket and $5 per bucket of popcorn. You never buy the popcorn because you think it's too expensive.
Is the total price you pay proportional to the number of tickets you buy?
Yes, the total price pay is proportional to the number of tickets.
What is proportionality?In mathematics, proportionality indicates that two quantities or variables are related in a linear manner.
Since you never plan to buy the popcorn but only the movie ticket, therefore we can definitely say that there is a direct correlation between the total price and the number of tickets bought.
Since, 1 ticket = $10.50
So,
The proportion equation is:
P = 10.50 t
where P is the total price and t is the number of tickets
Hence, the total price pay is proportional to the number of tickets.
