Thanks for asking!

Step-by-step explanation:

For ABD x equals 18 and for DBC equals 54.

Answer:

ABD = 36

DBC = 54

Step-by-step explanation:

The three angles form a straight line so they add to 180

2x + 3x +90 = 180

Combine like terms

5x+90 =180

Subtract 90 from each side

5x+90-90=180-90

5x= 90

divide each side by 5

5x/5 = 90/5

x =18

ABD = 2x = 2*18 = 36

DBC = 3x = 3*18 =54

Answer: 44

Step-by-step explanation:

88 is the total, 88 divided by 2 is 44 and half the seeds are radishes

Answer:

44 radish seeds

Step-by-step explanation:

Punita planted 88 seeds in total and half of them are radish seeds.

Multiply 88 by 1/2 or divide 88 by 2 to find what half of 88 is.

88 x 1/2 = 44

88/2 = 44

You may show your work either way.

To check your work:

44 radishes + 44 carrots = 88 seeds in total

or

44 times 2 = 88

Answer: Marble

To find Claire's rate in meters per second, we divide the distance she runs (400 meters) by the time it takes (45 seconds). This gives us a rate of approximately 8.89 meters per second.

The question is asking us to calculate Claire's rate in meters per second. To work out the rate of speed, we use the formula distance divided by time. In this case, the distance is 400 meters and the time is 45 seconds.

So we divide 400 by 45 which gives us 8.888 recurring. Therefore, Claire's rate is approximately 8.89 meters per second.

Answer:

72

Step-by-step explanation:

You need to add the two middle numbers then divide them by two.

Hope this helps.

Answer: 72

Step-by-step explanation: The median is the middle number in the data set when the data set is written from least to greatest.

Notice that our data set is already written from least to greatest so all we have to do now is find the number that appears in the middle.

Notice however that there are two numbers in the middle.

When this happens, take the sum of the two numbers in the middle or add them together and then divide the sum of the numbers by 2.

So if we add 71 + 73, we get 144.

Now just divide 144 by 2 to get 72.

So the median of the data set shown here is 72.

The given triangle is an acute scalene triangle.

Final answer:

The question concerns a college-level Physics model related to the Fokker-Planck equation and its application in classical and statistical mechanics, specifically in the context of explaining atomic stability, atomic size, and electron binding energy in atomic physics.

Explanation:

The equation and model described in the question appear to represent the principles of classical mechanics and statistical mechanics in Physics, especially when referencing the Fokker-Planck equation, which is used to describe the dynamics of a particle in a fluid with drag and fluctuations. This model is a two-dimensional first-order model similar to the one proposed nearly half a century ago by two physicists or applied mathematicians, which implies it has a historical significance in its contribution to physical theories. Additionally, the model and equation are going to be used with the Bohr model of the hydrogen atom to provide insights into atomic stability, atomic size, and electron binding energy within the atom, which is crucial for understanding atomic physics and quantum mechanics.

The Fokker-Planck equation includes a drift term that accounts for the deceleration of the particle due to drag, and a diffusion term representing the random walk of the particle's momentum due to fluctuations. The context provided suggests that these concepts are being applied to explain the behavior of a charged particle and that the coefficients from the linear model can be combined with operating parameters to derive specific equations for this system. This points to an advanced-level discussion suitable for College-level Physics courses where students are expected to have a foundation in these theories.

Erik saw 6 stars on Monday night

Step-by-step explanation:

42/7

To find out how many stars Erik saw on Monday, we divide the number of stars he saw on Tuesday (42) by 7 because Tuesday's count is seven times Monday's. Resulting in Erik seeing 6 stars on Monday.

The subject of this question is mathematics, specifically division. The number of stars Erik saw on Tuesday night, 42 stars, is given as seven times the number of stars he saw on Monday. We can solve for the number of stars on Monday night by using division. We take the total number of stars seen on Tuesday, 42, and divide by 7 (since Tuesday’s count is seven times Monday's count). This gives us:

42 ÷ 7 = 6 stars

Therefore, Erik saw 6 stars on Monday night.

Joshua tutored Eric on Saturday and Sunday to Ben. Joshua earned $4.50 more on Saturday than on Sunday.

Joshua tutored Eric on Saturday and Sunday to Ben.

On Saturday, Joshua charged $12.50 per hour for tutoring, and since he also charged the same rate for guitar lessons, the total earnings were based on the combined time spent on tutoring and guitar lessons.

He added a flat fee of $4.50 for traveling. With a total earning of $35.75, the equation can be set up as follows:

[tex]\[ \text{Total Earnings on Saturday} = (\text{Hourly Rate} \times \text{Total Hours}) + \text{Flat Traveling Fee} \][/tex]

[tex]\[ 35.75 = (12.50 \times \text{Total Hours}) + 4.50 \][/tex]

Solving for the total hours, we find that Joshua spent 2 hours tutoring and giving guitar lessons on Saturday.

On Sunday, Joshua spent 0.5 hours giving guitar lessons and the remaining time tutoring Ben. Without a flat rate for traveling, the total earnings on Sunday were $31.25. Joshua's hourly rate remains $12.50. The equation can be expressed as:

[tex]\[ \text{Total Earnings on Sunday} = (\text{Hourly Rate} \times \text{Total Hours}) \][/tex]

[tex]\[ 31.25 = (12.50 \times \text{Total Hours}) \][/tex]

Solving for the total hours, we find that Joshua spent 2.5 hours tutoring and giving guitar lessons on Sunday.

Therefore, Joshua tutored Eric for 2 hours and gave guitar lessons for the remaining time on Saturday. On Sunday, he gave guitar lessons for 0.5 hours and tutored Ben for 2.5 hours.

Question:

Felicia makes ½ gallon of fruit punch. She pours an equal amount into 8 glasses.

What fraction of a gallon fruit punch is in each glass?

Answer:

The fraction of a gallon fruit punch is in each glass is 1/16

Step-by-step explanation:

Given

Size of fruit punch = ½ gallon

Number of glass = 8

Required

Fraction of a gallon fruit punch is in each glass?

To solve this question, the following assumption has to be made.

- The 8 glass cups are of equal sizes.

Having said that;

The interpretation of the question is that, the fruit is evenly distributed into the 8 glass cups.

Mathematically, the size of the fruit punch will be divided by the number of glass cups.

So, we have

Fraction = ½ ÷ 8 (convert ÷ to *)

Fraction = ½ * ⅛

Fraction = 1/16

Hence, the fraction of a gallon fruit punch is in each glass is 1/16

Final answer:

To find the fraction of a gallon of fruit punch in each glass, divide 1/2 gallon by 8. This results in each glass containing 1/16 of a gallon of fruit punch.

Explanation:

The student asked how to find the fraction of a gallon of fruit punch in each glass if Felicia makes ½ gallon of fruit punch and pours an equal amount into 8 glasses. To answer this question, you need to perform a division of the total amount by the number of glasses. Given that Felicia has ½ gallon, which is the same as 2/4, we can divide this by 8 to find the amount in each glass.

Step-by-step solution:

Start with the fraction of a gallon Felicia has: ½ gallon.

Convert ½ to fourths to make the division easier: ½ = 2/4 gallons.

Since there are 8 glasses, divide 2/4 by 8. This is done by multiplying the denominator by 8:
(2/4) × (1/8) = 2/32.

Simplify the fraction by dividing numerator and denominator by the common factor of 2: 2/32 = 1/16.

Therefore, each glass contains 1/16 of a gallon of fruit punch.
