When mrs chang filled the gas tank in her truck, the gas gauge was at Empty. She spent 75$ for 20 gallons of gas. The next time the gas gauge was at Empty, dhe had driven over 480 miles. Write the ratios you can use to find the two unit rates that concerns most drivers: dollars per gallon and miles per gallon. Then find the unit rates. Explain your reasoning.
Mrs. Chang's truck runs at a unit rate of $3.75 per gallon of gas and 24 miles per gallon. These rates are found by dividing the total cost by gallons for the cost rate, and total miles by gallons for the efficiency rate.
Explanation:To find the unit rates of dollars per gallon and miles per gallon for Mrs. Chang's truck, we can use the ratios provided by the information given. First, to find the cost per gallon of gas, we divide the total amount spent by the number of gallons:
Cost per gallon = Total cost / Number of gallons = $75 / 20 gallons = $3.75 per gallon
To calculate the miles per gallon, we divide the number of miles driven by the number of gallons it took to fill the tank when it was empty again:
Miles per gallon = Total miles driven / Number of gallons = 480 miles / 20 gallons = 24 miles per gallon
By calculating these unit rates, drivers can determine both the price efficiency of their gasoline purchases and the fuel efficiency of their vehicle.

Step-by-step explanation:
Mr. Gaster has $5 in his piggy bank and wants to put $45 every week into the piggy bank. Make you equation showing how much money he will have at any number of day. Solve your equation to show the total amount of money Mr.Gaster will have in 28 days in his piggy bank. Make sure to show your work.
Final answer:
To find out how much money Mr. Gaster will have after any number of days, we create an equation based on his initial savings and weekly contributions. For 28 days, the equation is T = ($45 × (28/7)) + $5, which simplifies to T = $185. Therefore, Mr. Gaster will have $185 in his piggy bank after 28 days.
Explanation:
To determine how much money Mr. Gaster will have in any number of days, we need to create an equation that accounts for the initial amount and the weekly savings. Because there are 7 days in a week, Mr. Gaster will save $45 for every 7 days. Therefore, to find the total amount in the piggy bank after a certain number of days (d), we divide the number of days by 7 (to get the full weeks), multiply it by the weekly saving amount, and then add the initial amount.
Forming the Equation
Let T be the total amount, and the equation representing the situation is:
T = ($45 \times \frac{d}{7}) + $5
Solving for 28 Days
To solve for the total amount in 28 days:
T = ($45 \times \frac{28}{7}) + $5
T = ($45 \times 4) + $5
T = $180 + $5
T = $185
Hence, after 28 days, Mr. Gaster will have $185 in his piggy bank.
2. There are 14 bees in the hive and 17 bees in the garden. How many bees are there?
By adding the 14 bees in the hive to the 17 bees in the garden, we determine there are a total of 31 bees.
Explanation:To find out how many bees there are in total, we need to add the number of bees in the hive to the number of bees in the garden. The problem states that there are 14 bees in the hive and 17 bees in the garden. Adding these two quantities together gives us:
14 bees in the hive + 17 bees in the garden = 31 bees in total.
So, there are 31 bees altogether.
Final answer:
To find the total number of bees, you need to add the number of bees in the hive to the number of bees in the garden. The total number of bees is 31.
Explanation:
To find the total number of bees, you need to add the number of bees in the hive to the number of bees in the garden. In this case, there are 14 bees in the hive and 17 bees in the garden.
To find the total number of bees, add the number of bees in the hive and the number of bees in the garden: 14 + 17 = 31.
Therefore, there are 31 bees in total.

Paul is making loaves of raisin bread to sell at a fundraising event. The recipe calls for 1/3 cups of raisins for each loaf, and Paul has 3 1/4 cups of raisins. I need help with b.
Answer:
a. [tex]9\frac{3}{4}[/tex], from which he can make 9 loaves.
b. [tex]\frac{3}{4}[/tex] is the remaining part.
Step-by-step explanation:
Givens
The recipe calls for 1/3 cups of raisins for each loaf.Pauls has 3 1/4 cups of raisins.To find then number loaves that Paul can make, we just need to divide the number of cups of raising he has, and the cups of raisins need it according to the recipe.
[tex]3\frac{1}{4} \div \frac{1}{3}[/tex]
But, we first need to transform the mixed numero into a fraction, then we solve
[tex]3\frac{1}{4} \div \frac{1}{3}=\frac{13}{4} \div \frac{1}{3}=\frac{13}{4} \times \frac{3}{1}= \frac{39}{4}[/tex]
If we divide this fraction, we obtain a mixed number, becuase the division is not exact
[tex]\frac{39}{4}= 9\frac{3}{4}[/tex]
So, Paul can make [tex]9\frac{3}{4}[/tex] number of loaves. But, he cannot make an incomplete loaf, that means Paul can only make 9 loaves, and the remaining is 3/4, that's the "excess". You can get this answer by subtracting
[tex]9\frac{3}{4} - 9= \frac{39}{4}-9=\frac{39-36}{4}=\frac{3}{4}[/tex]
Therefore, the answers are
a. [tex]9\frac{3}{4}[/tex]
b. [tex]\frac{3}{4}[/tex]

Jeandre said |3| equals |-3|. Is Jeandre correct? Use a number line and words to support your answer.
Jeandre is correct because the absolute value of a number represents its distance from zero on a number line. Both |3| and |-3| are three units away from zero, therefore they have the same value of 3.
Jeandre is correct when he says that |3| equals |-3|. In mathematics, the absolute value of a number is the distance of that number from zero on a number line, regardless of direction. Both 3 and -3 are three units away from zero. Therefore, the absolute value of 3 is 3, and the absolute value of -3 is also 3.
To visualize this on a number line: if you start at zero and move three units to the right, you reach +3. If you move three units to the left of zero, you reach -3. Since absolute value is concerned with distance only and not direction, both |3| and |-3| represent a distance of 3 units from the origin, hence both have a value of 3.
The equals sign is used to indicate that both expressions are the same in value. Additionally, the rules of algebraic signs help to understand that the negative sign indicates direction on a number line, but does not affect the absolute value.

mr cho has twice as many dollar bills as quarters. his money in dollar bills and quarters totals $15.75. how many of each does he have?
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.

2. In the troposphere, as altitude increases, air temperature drops at a relatively uniform rate. At the top of the troposphere, an average depth of 11 km, the average temperature is -56.5°C. At the base of the troposphere, 0 km, the average temperature is 15°C. In a linear model of this situation, which of the following statements applies? An increase of 1 km in altitude corresponds to a increase of 3.8°C in temperature. An increase of 1 km in altitude corresponds to a decrease of 3.8°C in temperature. An increase of 1 km in altitude corresponds to a increase of 6.5°C in temperature. An increase of 1 km in altitude corresponds to a decrease of 6.5°C in temperature.
Answer: An increase of 1 km in altitude corresponds to a decrease of 6.5°C in temperature.
Step-by-step explanation: In a linear model of this situation, the y-intercept represents the temperature at the base of the troposphere, 15°C.
The rate of change, or slope, can be determined using two values: temperature at the base, (0 , 15), and temperature at the top, (11 , −56.5).
The linear model of this situation is y = 15 − 6.5x, where x represents the height of the troposphere, in kilometers.
The rate of change, or slope, indicates that an increase of 1 km in altitude corresponds to a decrease of 6.5°C in temperature. Hope this helps
Final answer:
In the troposphere, an increase of 1 km in altitude corresponds to a temperature decrease of 6.5°C, based on the given data of 15°C at sea level and -56.5°C at the top of the troposphere (11 km).
Explanation:
The question concerns the change of air temperature with altitude in the troposphere. From the information provided, we know that the temperature at the base of the troposphere (0 km) is 15°C and at the average top (11 km), it's -56.5°C. To find the rate at which temperature decreases with altitude, we can use the given temperatures at two different altitudes to calculate the lapse rate.
The difference in temperature from the base to the top is 15°C - (-56.5°C) = 71.5°C. Over a distance of 11 km, this gives us a lapse rate of 71.5°C / 11 km = 6.5°C/km. Therefore, an increase of 1 km in altitude corresponds to a decrease of 6.5°C in temperature.
how much does all the angles in a quadrilateral equal up to?
The sum of the interior angles in any quadrilateral is always 360 degrees.
The sum of the interior angles in a quadrilateral is always 360 degrees. This is a fundamental concept in geometry that applies to all quadrilaterals, regardless of their shape. To understand why this is the case, one can consider dividing a quadrilateral into two triangles. Since the sum of the angles in a triangle is always 180 degrees, adding the angles from both triangles within the quadrilateral gives us a total of 360 degrees. This rule is crucial when solving various geometrical problems involving quadrilaterals. For example, if a quadrilateral ABCD has an extended line CE creating two angles on a straight line, angles ACD and ACE would sum up to 180 degrees because angles on a straight line always sum up to 180 degrees.
It is also worth noting that if a quadrilateral has three right angles, the properties of the sides relative to the fourth angle can be determined based on whether that angle is right, acute, or obtuse. These principles are derived from the fundamental properties of angles in polygons and are used to deduce further geometric relationships.

what percent of 92 is 23
23 is approximately 25 percent of 92.
To determine the percentage, we need to find what portion of 92 is represented by 23. We can set up a proportion to solve for the percentage.
Let's assume the unknown percentage is 'p'. We can write the proportion as:
23 is to 92 as p is to 100.
This can be expressed mathematically as:
23/92 = p/100
To solve for 'p', we can cross-multiply:
23 x 100 = 92 x p
2300 = 92p
To isolate 'p', we divide both sides of the equation by 92:
2300/92 = p
Simplifying, we find:
25 = p
Therefore, 23 is approximately 25% of 92. This means that 23 is 25% of the whole value of 92. To verify this, we can calculate 25% of 92:
(25/100) x 92 = 0.25 x 92 = 23
Hence, 23 is indeed 25% of 92.
