Given that Mary has 2 bags of sweets. each of which contains same number of sweets.
Let us assume each bag contains x number of sweets.
After eating 4 sweets, total number of sweets left in two bags = x+x-4=2x-4
But given 2x-4 = 30
2x-4+4 = 30+4
2x=34
[tex]x=\frac{34}{2} = 17[/tex]
Hence there are 17 sweets in each bag at starting.
Mary had two bags with an equal number of sweets. After eating 4 sweets, she had 30 left, which means each bag originally contained 17 sweets.
To solve the problem of determining how many sweets were in each bag to start with, we must consider that Mary had two bags with an equal number of sweets and ended up with 30 sweets after eating 4 sweets. We can represent the initial number of sweets in each bag as 'x'. So the equation for the total number of sweets after she eats 4 is 2x - 4 = 30.
Let's solve this equation step by step:
Add 4 to both sides: 2x = 30 + 4
Simplify: 2x = 34
Divide both sides by 2 to solve for x: x = 34 / 2
Therefore, x = 17
This means that initially, there were 17 sweets in each bag.
Two buses go from Sacramento to San Diego. The express bus makes the trip in 6.8 hours and the local bus takes 10.2 hours for the trip. The speed of the express bus is 25 mph faster than the speed of the local bus. Find the speed of both buses.
Answer: Speed of local bus is 50 mph and speed of express bus is 75 mph
Step-by-step explanation:
let say speed of local bus = x
so speed of express bus = x + 25
Distance = Speed × Time
Distance traveled by local bus = x × 10.2 = 10.2x
Distance traveled by express bus = (x + 25) × 6.8
since Distance traveled by local bus is same as Distance traveled by express bus
⇒10.2x = (x + 25) × 6.8
⇒ 10.2x = 6.8x + 170
⇒ 10.2x - 6.8x = 170
⇒ x = 170/3.4 = 50
So Speed of local bus = x = 50 mph
and Speed of express bus = x + 25 = 50 + 25 = 75 mph
Final answer:
The speed of the local bus is 50 mph and the speed of the express bus is 75 mph.
Explanation:
Let's define the speed of the local bus as 'x'.
The speed of the express bus is 25 mph faster than the speed of the local bus, so the speed of the express bus can be represented as 'x + 25'.
We know that the time taken by the express bus is 6.8 hours and the time taken by the local bus is 10.2 hours.
Using the formula Speed = Distance / Time, we can set up two equations:
Distance / 6.8 = x + 25 (equation 1)
Distance / 10.2 = x (equation 2)
Since the distance is the same for both buses (Sacramento to San Diego), we can equate the distances in equation 1 and equation 2:
x + 25 = (10.2/6.8) * x
x + 25 = 1.5x
0.5x = 25
x = 50
Substituting the value of x in equation 1, we can find the speed of the express bus:
Distance / 6.8 = (50 + 25)
Distance = 6.8 * 75
Speed of the express bus = Distance / 6.8 = 75
So, the speed of the local bus is 50 mph and the speed of the express bus is 75 mph.
the letters that spell Mississippi are each written on separate tiles lying face down on a table. a tile is selected at random, the litter is recorded, and then the tile is placed face down on the table. then the process repeats. What is the theoretical of choosing a tile with the letter P?
Answer: The theoretical probability of choosing a tile with letter P =0.18
Step-by-step explanation:
Given word = MISSISSIPPI
Total number of letters in given the word = 11
Number of letter P in given word = 2
Let A be a event of choosing a tile with a letter P then
P(A) =Number of tiles with letter P / Total letters in given word
= 2 /11 = 0.18
The probability of choosing a tile with the letter P from the word 'Mississippi' is 1/11.
The probability of choosing a tile with the letter P can be calculated by determining the ratio of the number of P tiles to the total number of tiles.
In the word 'Mississippi', there is only 1 letter P. The total number of letters in 'Mississippi' is 11. Therefore, the probability of choosing a tile with the letter P is 1/11.
So, the theoretical probability of choosing a tile with the letter P is 1/11.

What’s the 59th term of the sequence 29,37,45
The 59th term of the sequence 29, 37, 45 is 493. The sequence is arithmetic with a common difference of 8. Applying the formula for the nth term of an arithmetic sequence, we calculate the 59th term as 493.
Explanation:Finding the 59th Term of an Arithmetic Sequence
To find the 59th term of the sequence (29, 37, 45), we first need to determine the common difference of the sequence. We do this by subtracting any term from the term that follows it. For example:
37 - 29 = 8
45 - 37 = 8
The common difference is 8.
This sequence is an arithmetic sequence where each term increases by 8 from the previous term. The formula to find the nth term of an arithmetic sequence is:
an = a1 + (n - 1) * d
where:
an is the nth term we want to find,a1 is the first term of the sequence,n is the term number,d is the common difference.Plugging in the values for the 59th term:
a59 = 29 + (59 - 1) * 8
a59 = 29 + 58 * 8
a59 = 29 + 464
a59 = 493
Therefore, the 59th term of the sequence is 493.

The graph shows a distribution of data.
What is the variance of the data?
- 0.0625
- 0.25
- 0.5
- 1.5
The curve is bell shaped, the distribution of data is equal on both sides , that is from mid point called mean.
50% of Data lies on both side of mean.
So,Equation 1.→ Mean - 2 × standard deviation=3.5
or,Equation 2. →Mean + 2 × standard deviation=4.5
x -2 a= 3.5
4 -2 a=3.5
4-3.5=2 a
2 a=0.5
[tex]a=\frac{0.5}{2}=0.25[/tex]
Using equation (2)
→ 4 +2 a=4.5
2 a=4.5-4
2 a=0.5
[tex]a=\frac{0.5}{2}=0.25[/tex]
So, Standard Deviation = 0.25
→Variance =(Standard deviation)²=a²=(0.25)²=0.0625
Option (A)→0.0625
To find the variance of data, calculate the average of the squared differences between each data point and the mean.

The flu fighters competed against 40 bands in the chicken soup county battles of the bands. The top 15% will compete in the all virus state finals.How many bands will compete in the finals?
We are given: The number of bands in the chicken soup county battles of the bands = 40.
The percentage of the all virus state finals will compete = 15% of the total number of bands given.
We have given 40 number of bands.
Therefore, the bands will compete in the finals = 15% of 40.
15% can be written as 0.15.
Therefore, 15% of 40 = 0.15 × 40 = 6.
Therefore, 6 bands will compete in the finals.Suppose f(x)=6x-2 and g(x)= 2x+4. Find each of the following functions.
a. (f+g) (x)
b. (f-g) (x)
Suppose f(x)=6x-2 and g(x)= 2x+4
a.
(f+g) (x) = 6x - 2 + 2x + 4
(f+g) (x) = 8x + 2
b.
(f-g) (x) = 6x - 2 -( 2x + 4)
(f-g) (x) = 6x - 2 - 2x - 4
(f-g) (x) = 4x - 6
Final answer:
The combined function (f+g)(x) is 8x + 2, and the function (f-g)(x) is 4x - 6.
Explanation:
To find the combined functions (f+g)(x) and (f-g)(x) for the given functions f(x)=6x-2 and g(x)=2x+4, we carry out the operations as follows:
Function (f+g)(x)
(f+g)(x) = f(x) + g(x) = (6x - 2) + (2x + 4).
Combine like terms:
(f+g)(x) = 6x + 2x - 2 + 4.
(f+g)(x) = 8x + 2.
Function (f-g)(x)
(f-g)(x) = f(x) - g(x) = (6x - 2) - (2x + 4).
Combine like terms and distribute the negative sign:
(f-g)(x) = 6x - 2x - 2 - 4.
(f-g)(x) = 4x - 6.

1. Andrew is renting a camera that cost d dollars per day for 8 days. He can only spend $3,000. Make a inequality that Andrew can use to find all values of d within his budget
2. The movie camera shoot 24 frames per second. The scene is 4 minutes long. How many frames are there in that scene?
3. Filmmakers shoot much more film than they eventually use. The ratio of film shot to film used is called the footage ratio. Andrew shot 9 hours of film for his movie that is 1 hour and 30 minutes long. What is his footage ratio?
1. The inequality 8d ≤ 3000 when Andrew is renting a camera that cost d dollars per day for 8 days. He can only spend $3,000.
2. There are 5760 frames in that scene.
3. Andrew's footage ratio is 6, meaning he shot 6 times more film than what was eventually used in his 1 hour and 30-minute movie.
1. Let's create an inequality to represent Andrew's budget for renting the camera. The cost of renting the camera per day is represented by "d" dollars. He wants to rent it for 8 days, and his budget is $3,000.
The total cost of renting the camera for 8 days is 8d dollars. Andrew's budget is $3,000.
So, the inequality would be:
8d ≤ 3000
This inequality ensures that the total cost of renting the camera (8d) does not exceed his budget of $3,000.
2. To find the number of frames in a scene, we need to multiply the frame rate (frames per second) by the duration of the scene (in seconds).
Given:
Frame rate = 24 frames per second
Duration of the scene = 4 minutes
First, convert the duration to seconds since the frame rate is given in frames per second:
4 minutes * 60 seconds per minute = 240 seconds
Now, multiply the frame rate by the duration:
Number of frames = 24 frames/second * 240 seconds = 5760 frames
So, there are 5760 frames in that scene.
3. To find the footage ratio, we need to compare the amount of film shot to the amount of film used.
Film shot = 9 hours
Film used = 1 hour and 30 minutes
First, convert the film used to hours:
1 hour and 30 minutes = 1.5 hours
Now, divide the film shot by the film used:
Footage ratio = Film shot / Film used
Footage ratio = 9 hours / 1.5 hours
Footage ratio = 6
So, Andrew's footage ratio is 6, meaning he shot 6 times more film than what was eventually used in his 1 hour and 30-minute movie.

what is the greatest number of tables you could use to serve dinner to 55 guest so that each table has a different number of guest
The greatest number of tables needed to serve dinner to 55 guests, with each table having a different number of guests, is 10 tables.
Explanation:To find the greatest number of tables needed to serve dinner to 55 guests so that each table has a different number of guests, we need to distribute the guests among the tables in a way that maximizes the number of tables. We can start by placing one guest at each table, then add one more guest to each subsequent table until there are no more guests remaining. This will result in the maximum number of tables, with each table having a different number of guests.
Let's see how this works:
After distributing the guests this way, we have used 10 tables, with each table having a different number of guests. Therefore, the greatest number of tables we could use to serve dinner to 55 guests, with each table having a different number of guests, is 10 tables.

I have this question and I need it answered quickly because it's due in two days!!!!
Answer:
The measure of angle RAN is 39 degrees.
Step-by-step explanation:
Given:
AI is the angle bisector of angle KAN, andAR is the angle bisector of angle KAIangle RAK = 13 degreesTo Find:
Measure of angle RAN
Calculations:
STEP 1 : We note that angle RAN = angle RAI + angle IAN (by the construction of the angles given in the problem).
So, we need to individually find the angles RAI and IAN in order to find the angle RAN
STEP 2 : Finding angle RAI
Given that AR if the bisector of angle KAI, therefore angle KAR = angle RAI
Also given that angle KAR = 13 degrees.
Therefore, angle RAI = 13 degrees.
STEP 3 : Finding angle IAN
Given that AI is the bisector of angle KAN, therefore angle KAI = angle IAN
Now,
angle KAI = angle KAR + angle RAI
= 13 + 13 degrees (using what we found out in STEP 1)
= 26 degrees
Therefore angle IAN = angle KAI = 26 degrees
STEP 4 : Finding angle RAN
As we noted in STEP 1,
angle RAN = angle RAI + angle IAN
= 13 + 26 degrees (using Steps 2 and 3)
= 39 degrees
Therefore, angle RAN = 39 degrees
