Saeed made 42 2/3 burgers.
Explanation:To solve this problem, we need to find out how much ground beef Saeed used to make tacos and how much he used to make quarter-pound burgers. Let's break it down step-by-step:
1. Saeed bought 21 1/2 lb of ground beef.
2. He used 1/4 of the beef to make tacos. So, 1/4 of 21 1/2 lb is (1/4) * 21 1/2 lb = 5 3/8 lb.
3. The remaining beef is 21 1/2 lb - 5 3/8 lb = 16 1/8 lb.
4. Saeed used 2/3 of the remaining beef to make quarter-pound burgers. So, 2/3 of 16 1/8 lb is (2/3) * 16 1/8 lb = 32/3 lb = 10 2/3 lb.
5. To find the number of quarter-pound burgers, we divide the weight of the beef used for burgers by the weight of each burger. Since each burger weighs 1/4 lb, we divide 10 2/3 lb by 1/4 lb to get:
10 2/3 lb ÷ 1/4 lb = 10 2/3 lb * 4 lb/1 = 42 2/3 burgers.
Therefore, Saeed made 42 2/3 burgers.
Final answer:
Saeed used 1/4 of the ground beef for tacos and the remaining 2/3 for quarter pound burgers. After calculating, we determined that he was able to make 43 quarter pound burgers.
Explanation:
To solve Saeed's ground beef problem, we need to perform sequenced calculations to determine how much beef was used for tacos, and how many quarter pound burgers were made with the remaining beef.
First, Saeed used 1/4 of the 21 1/2 lb of beef for tacos. To find out how much that is, multiply 21.5 lb by 1/4:
21.5 lb × 1/4 = 5.375 lb for tacos
Next, we subtract this amount from the original to find the remainder:
21.5 lb - 5.375 lb = 16.125 lb remaining
Now, Saeed uses 2/3 of the remaining beef for burgers. So, we calculate:
16.125 lb × 2/3 = 10.75 lb for burgers
Since each burger is a quarter pound, we divide the weight used for burgers by 1/4 to find out how many burgers he made:
10.75 lb ÷ 1/4 lb per burger = 43 burgers
Therefore, Saeed made 43 quarter pound burgers.
are two negative integers always sometimes or never positive explain your reasoning
Final answer:
Multiplying two negative integers always results in a positive integer because the negatives cancel each other out.
Explanation:
When you multiply two negative integers, the result will always be a positive integer. Each negative sign cancels the other out, leading to a positive product. For example, if you take two negative integers such as -2 and -3, when you multiply them (-2) x (-3), you obtain 6, which is a positive integer. This is a consistent rule in mathematics, so whenever you multiply two negatives, you can expect the result to be positive.

A pail holds 5 1/2 gallons of water. How much is this in cups? Write your answer as a whole number or a mixed number in simplest form. Include the correct unit in your answer.
5 1/2 gallons of water is equivalent to 88 cups of water. This is calculated by understanding that one gallon equals 16 cups, and therefore multiplying 5.5 (5 1/2 in decimal form) by 16.
Explanation:The subject of this question is a simple conversion in mathematics. To make this conversion, we need to understand the basic relationship between gallons and cups. In U.S. standard measurements, one gallon is equivalent to 16 cups. So, if we have 5 1/2 gallons, we would multiply this by 16 to get the equivalent number of cups. Hence, 5.5 (which is 5 1/2 in decimal form) multiplied by 16 equals 88. So, 5 1/2 gallons of water is equivalent to 88 cups of water.

What is the scale factor of 3,6 and 4.5, 9
The scale factor between the numbers (3, 6) and (4.5, 9) is 2, since the second number in each pair is twice as large as the first number.
Explanation:The scale factor is a ratio that describes how to enlarge or reduce the dimensions of an object to create a new object that is similar to the original. To figure out the scale factor between two similar figures, we calculate the ratio of any two corresponding lengths in the figures.
As per the student's question:
For the pair of numbers (3, 6), the scale factor can be calculated by dividing 6 by 3, which gives us a scale factor of 2.For the pair of numbers (4.5, 9), dividing 9 by 4.5 gives us a scale factor of 2 as well.In each case, the corresponding lengths in the second object are twice those in the first, meaning you can multiply the dimensions of the first figure by 2 to get the dimensions of the second figure.

How can I rename 82 thousands?
82 thousands can be renamed as 8 ten thousands and 2 thousands, or as 0.082 hundred thousands in the decimal system.
Explanation:Renaming 82 thousands means expressing this amount in another unit of place value. In the standard decimal system, the next unit larger than thousands is ten thousands. The digit in the ten thousands place represents the number of ten thousands in that number. If you have 82 thousands, this equals 8 ten thousands and 2 thousands, because 82 divided by 10 equals 8 with a remainder of 2. Therefore, 82 thousands can be renamed as 8 ten thousands and 2 thousands. Similarly, 82 thousands can also be expressed as 0.082 hundred thousands, as 82 divided by 1000 equals 0.082.

Which expression shows how 8⋅54 can be rewritten using the distributive property
The expression 8⋅54 can be rewritten as 8⋅(50 + 4) using the distributive property. This mathematical property allows us to break down the sum and perform the multiplication individually.
Explanation:The expression 8⋅54 can be rewritten using the distributive property in mathematics as 8⋅(50 + 4). This property allows you to multiply a sum by breaking it into two parts - in this case, 54 is broken down into 50 and 4. The multiplication is then performed on both these parts separately. When using the distributive property, we follow the steps:
1. Identify the number to be distributed, in this case, it's 8.
2. Break down the other number into two simpler components we can easily multiply with, like 50 and 4 for 54.
3. Multiply the distributing number with each of these parts separately. That gives us: 8⋅50 and 8⋅4.

Answer:
look at the screenshots below! all correct test answers!
Step-by-step explanation:
The sum of the charges in the neon atom is 0 if the neon atom has 10 protons and 10 electrons and the 10 protons have a charge of +10 and the 10 electrons have a charge of −10.
What is a number line?It is defined as the representation of the numbers on a straight line that goes infinitely on both sides.
It is given that:
A neon atom has 10 protons and 10 electrons. The 10 protons have a charge of +10 and the 10 electrons have a charge of −10.
No other particles in the atom have a charge.
Total charge:
= sum of the charge on the electron + sum of the charge of the protons
As we know, the arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
Total charge = +10 + (-10)
Total charge = +10 -10
Total charge = 0
If we plot the above situation on a number line we will get the total charge is zero.
Thus, the sum of the charges in the neon atom is 0 if the neon atom has 10 protons and 10 electrons and the 10 protons have a charge of +10 and the 10 electrons have a charge of −10.

Drake lives 7/8 mile from the park. After walking 2/3 of the way to the park, he met Scott. How far had Drake walked when he met Scott?
To find the distance Drake walked, calculate 2/3 of 7/8 mile, which results in 14/24, and simplify this fraction to 7/12 mile. Therefore, Drake walked 7/12 mile when he met Scott.
Drake lives 7/8 mile from the park. To find out how far he walked when he met Scott after walking 2/3 of the way to the park, you need to calculate 2/3 of 7/8 mile. The calculation is as follows:
Distance walked = (2/3) * (7/8)
First, multiply the numerators together: 2 * 7 = 14.
Then, multiply the denominators together: 3 * 8 = 24.
Now, put it together:
Distance walked = 14/24
We can simplify this fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 2.
So, 14 / 2 = 7 and 24 / 2 = 12.
Therefore, the simplified fraction is 7/12 mile.
Drake walked 7/12 mile when he met Scott.

What is the mean and median for the length of 20.3 12.5 7.6 13.9 9.2 21.7 7.6 17.5 15.6 14.1
Mean = 14
and Median = 14
Step-by-step explanation:We are given a data set as:
20.3 12.5 7.6 13.9 9.2 21.7 7.6 17.5 15.6 14.1
there are a total of 10 data points.
Now, the mean of these data points is the average of the data set.
i.e.
[tex]\text{Mean}=\dfrac{\text{Sum of data points}}{\text{Number of data points}}[/tex]
i.e.
[tex]\text{Mean}=\dfrac{20.3+12.5+7.6+13.9+9.2+21.7+7.6+17.5+15.6+14.1}{10}\\\\\text{Mean}=\dfrac{140}{10}\\\\\text{Mean}=14[/tex]
We know that median is the central tendency of the data and it always exist in the middle of the data set.
Firstly we arrange the data points in the increasing order as follows:
7.6 7.6 9.2 12.5 13.9 14.1 15.6 17.5 20.3 21.7
Now, we know that the median of the data exist in between 13.9 and 14.1
i.e.
[tex]\text{Median}=\dfrac{13.9+14.1}{2}\\\\\text{Median}=\dfrac{28}{2}\\\\\text{Median}=14[/tex]
