Median: The middle number when all the numbers are listed in order.
To find the median of the data set shown here, we can first start by putting all the numbers in order from least to greatest.
Least to greatest - 5, 5, 7, 10, 13
Next, we locate the number that is exactly in the middle and if there is no number exactly in the middle, we find the two numbers and find halfway point between them.
The number that is exactly in the middle of the data set is 7 so our median is 7.

uses a total of 4 pounds of meat.
If he uses a 3 to 1 ratio of beef to pork, how
much pork will he use? Enter your answer as a
mixed number in simplest terms.
Total meat in the recipe he wants to use = 7 pounds
Beef : pork = 3 : 1
Total pork that he will use = x 7 pounds
= 7/4 pounds
hope this helps
Answer:
Amount of pork used was 1 pound.
Step-by-step explanation:
Mike wants to make meatloaf by adding beef and pork.
Ratio of the meat (beef and pork) is = 3 : 1
Recipe requires total amount of meat = 4 pounds
So the amount of pork used in the recipe = [tex]\frac{1}{(1+3)}\times 4[/tex]
= [tex]\frac{1}{4}\times 4[/tex]
= 1 pound
Therefore, total amount of pork used in the recipe is 1 pound.
20. Acid Mixture Bill Charlson needs 10% hydrochloric acid
for a chemistry experiment. How much 5% acid should he
mix with 60 milliliters of 20% acid to obtain a 10% solution?
Answer:
120 ml
Step-by-step explanation:
Let x ml of 5% acid should mix with 60 milliliters of 20% acid to obtain a 10% solution,
Thus, the quantity of resultant mixture = ( x + 60 ) ml,
Also,
Acid in x ml 5% acid + Acid in x ml 5% acid = acid in 10% resultant solution,
5% of x + 20% of 60 = 10% of ( x + 60)
[tex]\frac{5x}{100}+\frac{20\times 60}{100}=\frac{10\times (x+60)}{100}[/tex]
[tex]5x + 1200 = 10x + 600[/tex]
[tex]5x - 10x = 600 - 1200[/tex]
[tex]-5x = -600[/tex]
[tex]\implies x = \frac{-600}{-5}=120[/tex]
Hence, 120 ml of 5% acid should be mixed.

Find three consecutive integers so that the
sum of the first two integers is 10 more than the third
integer.
Final answer:
The three consecutive integers that satisfy the condition are 11, 12, and 13. These numbers are such that the sum of the first two is equal to the third integer plus 10.
Explanation:
The question asks to find three consecutive integers where the sum of the first two is 10 more than the third. To solve this, let's call the smallest integer 'x'. Therefore, the next two consecutive integers will be 'x+1' and 'x+2'. The problem states that the sum of the first two integers is 10 more than the third, which gives us the equation: x + (x + 1) = (x + 2) + 10.
Simplifying this equation gives us 2x + 1 = x + 12. To find the value of 'x', we subtract 'x' from both sides of the equation, which gives us x + 1 = 12. Next, we subtract 1 from both sides to get x = 11. The three consecutive integers in question are therefore 11, 12, and 13.
Checking our work: the sum of the first two integers is 11 + 12 = 23. The third integer plus 10 is 13 + 10 = 23. Since both sums are equal, our solution is correct.
Final answer:
To find three consecutive integers, let the first integer be x, the second integer be x+1, and the third integer be x+2. Solve the equation x + (x+1) = (x+2) + 10 to find x, then determine the three consecutive integers.
Explanation:
To find three consecutive integers, we can let the first integer be x, the second integer be x+1, and the third integer be x+2. We are given that the sum of the first two integers is 10 more than the third integer. This can be written as:
x + (x+1) = (x+2) + 10
Combining like terms and solving the equation, we get:
2x + 1 = x + 12
x = 11
So the three consecutive integers are 11, 12, and 13.

Jackie cut a 2-yard spool into 5 equal lengths of ribbon.
a. What is the length of each ribbon in yards? Draw a tape diagram to show your thinking.
b. What is the length of each ribbon in feet? Draw a tape diagram to show your thinking.
Answer:
a. [tex]\frac{2}{5}[/tex] yard
b. 1.2 feet
Step-by-step explanation:
a. Jackie cut a 2-yard spool into 5 equal length of ribbon.
We will divide 2 yard by 5 = 2 ÷ 5 = [tex]\frac{2}{5}[/tex] yard
5 units = 2 yard
1 unit = [tex]\frac{2}{5}[/tex] yard
Check : [tex]\frac{2}{5}[/tex] + [tex]\frac{2}{5}[/tex] + [tex]\frac{2}{5}[/tex] + [tex]\frac{2}{5}[/tex] + [tex]\frac{2}{5}[/tex] = [tex]\frac{10}{5}[/tex] = 2
b. Length of each ribbon in feet
Since 1 yard = 3 feet
therefore, 2 yard = 3 × 2 = 6 feet
6 feet in to 5 equal part = 6 ÷ 5
= 1.2 feet
check : 1.2 + 1.2 + 1.2 + 1.2 + 1.2 = 6.0 feet
Each ribbon cut from a 2-yard spool into 5 equal parts will be 0.4 yards or 1.2 feet in length. Tape diagrams represent this division into equal parts.
Explanation:To determine the length of each ribbon when a 2-yard spool is cut into 5 equal lengths, you need to divide the total length by the number of pieces.
2 yards ÷ 5 = 0.4 yards for each piece.To represent this with a tape diagram, imagine a line equally divided into 5 sections, with each section representing 0.4 yards.
For the length in feet, since 1 yard equals 3 feet, we multiply the length in yards by 3.
To show this with a tape diagram, you can divide a line into 5 sections with each section representing 1.2 feet.
5,500,000 in expanded form
Answer:
5,500,000 = (5 x 100000000) + (0 x 10000000) + (5 x 1000000) + (0 x 100000) + (0 x 10000) + (0 x 1000) + (0 x 100) + (0 x 10) + (0 x 1)
Step-by-step explanation:
The expanded form of 5,500,000 is (5 x 1000000) + (5 x 100000) + (0 x 10000) + (0 x 1000) + (0 x 100) + (0 x 10) + (0 x 1).
What is an expanded form?
The expanded form of the number is the splitting of numbers based on the place value, such as ones, tens, hundreds, thousands, ten thousands,and so on. The number that is represented by the sum of each digit multiplied by its place value is called the expanded form of the number.
Now the given number is,
5,500,000
Now each digit place value is given as,
5 = (5 x 1000000)
5 = (5 x 100000)
0 = (0 x 10000)
0 = (0 x 1000)
0 = (0 x 100)
0 = (0 x 10)
0 = (0 x 1)
Adding this together, we get
5,500,000 = (5 x 1000000) + (5 x 100000) + (0 x 10000) + (0 x 1000) + (0 x 100) + (0 x 10) + (0 x 1).
Hence, The expanded form of 5,500,000 is (5 x 1000000) + (5 x 100000) + (0 x 10000) + (0 x 1000) + (0 x 100) + (0 x 10) + (0 x 1).

Answer:
Two thirds of the Senate must approve it
The minimum number of Senate members needed to approve a treaty is two-thirds of the Senate.
Explanation:The minimum number of members of the Senate that must approve a treaty for it to go into effect is two-thirds (⅔) of the Senate. The Constitution of the United States, Article II, Section 2, Clause 2 states that the President has the power to make treaties, but they require the advice and consent of the Senate.
For example, if the Senate has 100 members, then 67 votes would be needed to approve a treaty for it to go into effect. However, it is important to note that the Senate may require a supermajority vote, which would mean a higher percentage of approval than two-thirds, depending on their rules and procedures.

Answer:
Rafael gets $4,32 In tips. The old lady gets $41.68 in change.
Step-by-step explanation:
Step 1: To calculate the tip we must take into account that it is 8% of the total amount of the bill.
$54 * 8%/100% = $4,32
Rafael gets $4,32 In tips.
Step 2: Now we must calculate the change the old lady receives. For this, we must subtract from the $100 that she gives the part corresponding to the payment for food and the part corresponding to the tip.
$100 - $54 - $4,32 = $41,68
The old lady gets $41.68 in change.

Step-by-step explanation:
Rounding depends on the place value, if you are rounding to the nearest thousand, look at the number in the hundred place. Is that number lower or higher than 5? If lower, the place you are rounding to stays the same, and the places below it turn to zeros. If 5 or higher, round up, add 1 to the place you are rounding to, then turn the places below to zeros.
In this case, the hundreds place is a 4. Meaning you round down.

To find the original price of the item that was reduced by 20% to $126.40, divide the sale price by 0.80, which yields an original price of $158.00.
To determine the original price of an item that has been marked 20% off, we need to work backward from the sale price. The sale price represents 80% of the original price because 100% - 20% = 80%.
The question is provided with the reduced price which is $126.40. To find the original price, we divide the reduced price by 0.80.
Express 20% as a decimal: 0.20.Subtract this from 1 to find the percentage of the original price represented by the sale price: 1 - 0.20 = 0.80.Divide the sale price by this decimal: $126.40 / 0.80 = $158.00.Therefore, the original price of the item was $158.00.

Answer:
D. 16.8
Step-by-step explanation:
It is right trust me!!!
Answer:
Additional amount of clearance between the truck and overpass is 16.8 inches.
Step-by-step explanation:
A law states that a a freight truck must have the clearance of at least 3 feet to travel under the a overpass.
Sign on an overpass states that the overpass is 18 feet above the road's surface.
Height of the truck is 13.6 feet.
As per rule height of overpass from the road must be height of the truck + clearance.
Additional amount of clearance between the truck and the overpass
= Distance between the road and the overpass - (height of the truck + clearance)
= 18 - (13.6 + 3)
= 18 - 16.6
= 1.4 feet
Since 1.4 feet = 12 inches
1.4 feet = 12×1.4 = 16.8 inches
Therefore, additional amount of clearance between the truck and overpass is 16.8 inches.
