Brad paid for a book that cost $13.40 with a $20 bill. What is the least combination of coins and bills that can be used to make his change? What are two other different combinations of coins and bills that can be used to make the change?
Answers
Answer:
First combination: One $5 bill, one $1 bill, two quarters and one dime.
Second combination: One $5 bill, one $1 bill, two quarters and two nickles.
Step-by-step explanation:
I highly suggest reading it to make sure you understand it
Okay so for this one you're going to want to do 20.00-13.40. The answer to that is 6.60
So we have to work with $6.60
Now lets think of the obvious/easiest.
A $5 bill is going to be our best friend in this.
We have to do
6.60-5.00=x
(Don't freak out about x, it's just our place marker!!)
The reason we do 5.00 is because that's what $5 is.
So let's solve now.
6.60-5.00=1.60
So x=1.60
But you don't have to worry about x, I'm just explaining it from before.
So we have to keep in mind that we used one $5 bill. Now let's use one $1 dollar bill.
1.60-1.00=0.60
So now we only have to figure out how to get 60 cents from any of the coins.
A quarter is 25 cents so lets use two of those
25+25=50
60=50=10
Lets recap on everything we've used so far.
We've used one $5 bill, one $1 bill, and two quarters.
Now we're going to add a dime to the mix.
A dime is worth 10 cents.
So for the first combination we used: One $5 bill, one $1 bill, two quarters and one dime.
Now our second combination is going to be really easy.
We can use almost everything the exact same, we're only going to switch up the dime part.
1 dime = 2 nickles
Nickles are worth 5 cents
So we take out the dime and replace it with two nickles.
So for the second combination we use: One $5 bill, one $1 bill, two quarters and two nickles.
Which expression shows 12 more than the quotient of 63 and 9. Responses A (12 + 9) ÷ 63(12 + 9) ÷ 63 B 12 + 63 ÷ 912 + 63 ÷ 9 C 12 + 9 ÷ 6312 + 9 ÷ 63 D (12 + 63) ÷ 9
Answers
The correct expression which shows 12 more than the quotient of 63 and 9 is option B) \(\sf 12 + (63 \div 9)\).
What is a quotient?In arithmetic, a quotient (from 'how many times', pronounced) is a quantity produced by the division of two numbers.
We have to find the expression which shows 12 more than the quotient of 63 and 9.
For that, first find the quotient of 63 and 9.
Divide 63 by 9.
\(\sf \dfrac{63}{9} = 7\)
12 more than the quotient of 63 and 9 \(\sf = 7 + 12 = 19\)
So the result is 19.
Now, we have to mathematically write the given word sentence.
12 is added to the quotient of 63 and 9.
12 is added to \((63 \div 9)\)
\(\sf 12 + (63 \div 9)\)
Thus, B is the correct option.

A fruit juice recipe calls for 2 parts orange juice and 8 parts pineapple juice. Which proportion can be used to find the amount of orange juice, j, that is needed to add to 18 L of pineapple juice?
2 over 8 equals j over 18
8 over 2 equals j over 18
8 over j equals 2 over 18
16 over 18 equals j over 100
Answers
The correct proportion to use to find the amount of orange juice, j, needed to add to 18 L of pineapple juice is:
2/8 = j/18
This proportion relates the ratio of orange juice to pineapple juice in the recipe (2:8) to the amount of orange juice needed to add to 18 L of pineapple juice. By cross-multiplying, we can solve for j as follows:
2/8 = j/18
218 = 8j
36 = 8*j
j = 36/8
j = 4.5
Therefore, you would need to add 4.5 L of orange juice to 18 L of pineapple juice to create the fruit juice recipe that calls for a ratio of 2 parts orange juice to 8 parts pineapple juice.
Answer:
2 over 8 equals j over 18Step-by-step explanation
2 over 8 equals j over 18
This proportion represents the ratio of orange juice to pineapple juice in the recipe. By setting up the proportion, we can solve for the value of 'j,' which represents the amount of orange juice needed.
So, the correct proportion is:
2 over 8 equals j over 18

B = 25 + .05M
20 minutes a day for 30 days = 600 minutes per month
A(600) = 40+.1(100) = $50
B(600) = 25 + .05(100) = $30
Plan B is less expensive
40+.1(M-500)= 25+.05M
40-25- .1(500) = .05-.1M
.05M = 35
M= 35/.05 = 700 minutes will have the same cost under plan A or B
40+.1(200) = $60 under plan A
25+.05(700) = $60 under plan B

The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?
Answers
Answer:
25.685 square feet.
Step-by-step explanation:
Circumference = 2 * π * radius
From this, we can derive the formula for the radius:
radius = Circumference / (2 * π)
Let's substitute the value of the circumference and calculate the approximate radius:
radius = 18 / (2 * π)
radius ≈ 18 / (2 * 3.14159)
radius ≈ 2.865 feet
Now that we have the approximate radius, we can calculate the area:
Area ≈ π * radius²
Area ≈ 3.14159 * (2.865)²
Area ≈ 3.14159 * 8.193225
Area ≈ 25.685 square feet
Therefore, the approximate area inside the circular park is approximately 25.685 square feet.
C = 2πr
where C is the circumference and r is the radius of the circle.
In this case, we are given that the circumference is approximately 18 feet, so we can set up the following equation:
18 = 2πr
Solving for r, we get:
r = 9/π ≈ 2.864 feet
Now we can use the formula for the area of a circle:
A = πr^2
Substituting the value we found for r, we get:
A = π(2.864 ft)^2 ≈ 25.85 ft^2
Therefore, the approximate area inside the circular park is approximately 25.85 square feet.

112 meters--------------------------------
The heights and shadows are proportional since they form similar triangles.
Set equal proportions and solve for the missing length:
H/h = S/s, where H and h represent heights, S and s - shadows.H/3.2 = 39.75/1.14H = 3.2*39.75/1.14H = 112 (rounded)Answer:
112 meters
Step-by-step explanation:

Use a number line to order the numbers from least to greatest.
Answers
Assign the numbers to the number line in the following order:
2.15=2.15
220%=2.2
9/4=2.25
*2.15* is easy enough to place as it is already in decimal form. However, the other 2 options need to be converted to decimals in order to be placed. We have the fraction 9/4 and percentage 220%. 9/4 can either be simply divided on a calculator or turned into the mixed fraction 2 and 1/4, which is *2.25*. Finally, we know that converting a decimal to a percentage we multiply the decimal by 100. Therefore, to convert a percentage to a decimal we divide 100 or move the decimal to the left 2 places. With this conversion rule, 220% transforms to *2.2* and we have the third and final number for our number line. Arranging these three numbers from least to greatest:
2.15, 2.2, 2.25
if 4/4 is 1 then 9/4 is 2 whole with 1/4 left
220%=2.2 and 2.15 is still 2.15
