Final answer:
Mr. Cho has 7 quarters and 14 dollar bills. We find this by setting up an equation considering that he has twice as many dollar bills as quarters and their total value is $15.75. Solving the equation, we find the number of quarters (q) to be 7 and the number of dollar bills to be twice that amount.
Explanation:
Mr. Cho has twice as many dollar bills as quarters, and their total value is $15.75. To find out how many of each he has, let's set up some equations based on this information. Let's call the number of quarters q and the number of dollar bills 2q (since he has twice as many dollar bills as quarters).
Since each quarter is worth $0.25, the total value of the quarters would be 0.25q. The total value of the dollar bills would just be 2q (since each dollar bill is worth $1). The combined value of the quarters and dollars is given as $15.75, so we can set up the following equation:
0.25q + 2q = 15.75
Combining like terms:
2.25q = 15.75
Dividing by 2.25:
q = 15.75 / 2.25
q = 7
Therefore, Mr. Cho has 7 quarters. Since he has twice as many dollar bills as quarters, he has:
2q = 2 * 7 = 14 dollar bills.
In summary, Mr. Cho has 7 quarters and 14 dollar bills.

there are 1505 fruits for sale at a Farmers Market 39% of them are apples 28% are oranges 13% are honeydew melons and the rest are watermelons how many watermelons are there
Final answer:
As per the given case, there are 301 watermelons.
Explanation:
To calculate the number of watermelons at the farmer's market, we need to subtract the percentages of apples, oranges, and honeydew melons from the total percentage (100%) and then apply that percentage to the total number of fruits available. The calculations are as follows:
Percentage of apples: 39%Percentage of oranges: 28%Percentage of honeydew melons: 13%Total percentage of these three fruits: 39% + 28% + 13% = 80%
Percentage of watermelons = 100% - 80% = 20%
So, if 20% of the fruits are watermelons, and there are 1505 fruits in total, we calculate the number of watermelons as follows:
Number of watermelons = 20% of 1505 = 0.20 × 1505 = 301 watermelons
Therefore, there are 301 watermelons for sale at the farmer's market.

Jessie estimated the weight of his cat to be 12 pounds. The actual weight of the cat is 15 pounds.
What is the percent error?
Round your answer to the nearest whole percent.
Enter your answer in the box.
Answer:
The answer is 20%
Step-by-step explanation:
The percent error is 20%
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
+ Addition operation: Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
We have been given that Jessie estimated the weight of his cat to be 12 pounds. The actual weight of the cat is 15 pounds.
We have to determine the percent error.
Here the percent error is the percentage of the difference between the estimated weight and actual weight of the cat.
So the percent error is
⇒ the percentage of (15 - 12)/15 = (3/15) = 20 %

What is the unit rate 360 miles traveled on 12 gallons of gasoline
We are required to find the unit rate in miles per gallons of gasoline.
The unit rate 360 miles traveled on 12 gallons of gasoline is 30 miles per gallon
Units rate refers to the single unit of one quantity to another. for example; unit of miles to gasolineTotal miles travelled = 360 miles
Total gallons used = 12 gallons
Unit rate in miles per gasoline = Total miles travelled / Total gallons used
= 360 miles / 12 gallons
= 30 miles / 1 gallon
Unit rate in miles per gasoline = 30 miles per gallon
Therefore, the unit rate 360 miles traveled on 12 gallons of gasoline is 30 miles per gallon

If you multiply me by 7, subtract 2 and then divide by 6, you get 9. What number am I ?
The number in question is 8. Multiplying it by 7, subtracting 2, and dividing the result by 6 gives you 9.
To find the number that, when multiplied by 7, subtracted by 2, and then divided by 6, results in 9, we can set up the equation to solve for the unknown number (let's call it x):
7x - 2 = 54 (since 6 times 9 equals 54)
7x = 54 + 2
7x = 56
x = 56 / 7
x = 8
So the number you're looking for is 8 because when you multiply 8 by 7, subtract 2, and then divide by 6, you indeed get 9.

Step-by-step explanation:
You water the plants in your classroom at a constant rate. After 5 seconds, your watering can contains 58 ounces of water. Fifteen seconds later, the can contains 28 ounces of water.
a. Write an equation in slope-intercept form that represents the amount yy (in ounces) of water in the can after xx seconds.
To write an equation in slope-intercept form, we can use the given points to find the slope and y-intercept of the line. The equation that represents the amount of water in the can after x seconds is y = -2x + 68.
Explanation:To write an equation in slope-intercept form, we need to find the equation of a line in the form y = mx + b, where m is the slope and b is the y-intercept.
Given that the watering can contains 58 ounces of water after 5 seconds and 28 ounces of water after 20 seconds, we can use these two points to find the slope (m).
m = (28 - 58) / (20 - 5) = -30 / 15 = -2
Next, we can substitute one of the points and the slope into the equation and solve for b:
58 = -2(5) + b
b = 68
Therefore, the equation that represents the amount of water in the can after x seconds is
y = -2x + 68
Therefore, the equation in slope-intercept form that represents the amount y (in ounces) of water in the can after x seconds is y = -2x + 68.
To write the equation in slope-intercept form that represents the amount y (in ounces) of water in the can after x seconds, we need to determine the rate at which the water level decreases over time.
Given data:
- After 5 seconds, the can contains 58 ounces of water.
- After 20 seconds (5 seconds + 15 seconds), the can contains 28 ounces of water.
Let's define our points based on this data:
- First point: (5, 58) (5 seconds, 58 ounces)
- Second point: (20, 28) (20 seconds, 28 ounces)
Now, let's find the slope m of the line passing through these two points. The slope m is calculated as:
[tex]\[ m = \frac{y_2 - y_1}{x_2 - x_1} \][/tex]
[tex]\[ m = \frac{28 - 58}{20 - 5} \][/tex]
[tex]\[ m = \frac{-30}{15} \][/tex]
[tex]\[ m = -2 \][/tex]
Now that we have the slope m, we can use the point-slope form of the equation of a line, [tex]\( y - y_1 = m(x - x_1) \)[/tex], where [tex]\( (x_1, y_1) \)[/tex] is one of our points. Let's use the point (5, 58):
[tex]\[ y - 58 = -2(x - 5) \][/tex]
Now, simplify and solve for y to get the equation in slope-intercept form (y-intercept form), y = mx + b:
[tex]\[ y - 58 = -2x + 10 \][/tex]
[tex]\[ y = -2x + 10 + 58 \][/tex]
[tex]\[ y = -2x + 68 \][/tex]
