Benjamin started her walk from the front door of her ground floor apartment. She walked 6 meters to the corner of the building and then turned the corner and walked 10 meters to her friend's apartment.
Answers
Answer:
4 meters.
Step-by-step explanation:
Benjamin has walked two legs of a right triangle, so you can connect her two movements with a line if you were sketching the situation.. The displacement is the objects overall change in position in relation to its origin, so in your case, Benjamin's apartment. While the total distance adds up regardless of her position.
So, the total distance Benjamin walked is 10m + 6m = 16m
Her displacement can be found by your best friends, the Pythagorean Theorem: 10m ^2 + 6m ^2 = delta x^2 (or displacement squared).. giving you a displacement of 11.66, or 12 m.
The difference between the distance she walked and her displacement is 4 meters.

Scientists researching amphibians put tags on 30 frogs in a wetland area. Later, the scientists captured 520 frogs, of which 12 had tags. To the nearest whole number, what is the best estimate for the frog population?
Answers
Final answer:
The best estimate for the frog population, calculated using the mark-recapture method where 30 frogs were initially tagged and later 12 tagged frogs were found in a sample of 520, is approximately 208 frogs.
Explanation:
The question involves estimating the total population of frogs in a wetland area based on a mark-recapture study. The calculation is based on a proportion set up by the initial number of tagged frogs to the total initial tagging, compared with the number of tagged frogs found in a later sample to the size of that sample. This is a classic example of a capture-recapture method used in ecology for estimating population sizes.
The initial number of tagged frogs is 30, and later, from a sample of 520 frogs, 12 are found to be tagged. To estimate the total population (N), we set up the proportion as follows:
30 tagged frogs / N total population = 12 tagged frogs / 520 sample size
Now we cross-multiply and solve for N:
30N = 12 × 520
N = (12 × 520) / 30
N = 6240 / 30
N = 208
Therefore, the best estimate for the total frog population is approximately 208 frogs, rounded to the nearest whole number.

Which number is a common factor of 116 and 40
Answers
Answer:
4
Step-by-step explanation:
[tex]116 = 2 \times 2 \times 29 \\ 40 = 2 \times 2 \times 2 \times 5 \\ common \: factors = 2 \: \: 2 \\ common \: factors \: of \: 116 \: and \: 40 \\ = 2 \times 2 = 4[/tex]
The numbers 116 and 40 share common factors of 1, 2, and 4, with 4 being their greatest common factor.
The common factor of 116 and 40 can be found by identifying the numbers that divide both without leaving a remainder. To do so, we factorize both numbers:
116 = 2 x 2 x 29 = 2² x 2940 = 2 x 2 x 2 x 5 = 2³ x 5Next, we find the common factors by looking at the prime factors they share. Both numbers have the prime number 2 as a factor. The highest power of 2 that divides both numbers is 2², which is 4. Therefore, the greatest common factor (GCF) is 4. However, since we are looking for a common factor, not necessarily the greatest, 2 and 1 are also common factors of 116 and 40.

Allison's cinema has 100 seats. One day, Allison notices that her cinema is full, and she has taken exactly £100. The prices where: adult=£3.50, pensioner= £1, child=£0.85. she knows not everyone in the audience is a pensioner. Howmmany adults, children and pensioners where there?
Answers
Answer:
So starting with what we already know, £100 was paid in all, all 100 seats were taken. Adults pay £3.50, Children pay $0.85 and the Pensioners pay $1.00. I basicaly started off by trying it so all adults, children and pensioners are the exact same number. 33 adult tickets would cost them £115.50. Crossing that suggestion out; I tried again, but this time, with 3 adults, 50 children and the 47 that were left, i put as pensioners. So, now there is 100 people and this is kind of working out:
3 adults= £10.50, 50 children= £42.50, 47 pensioners= £47.00 Total £100
Step-by-step explanation:
As per the given data number of adults [tex]=3[/tex] , number of children [tex]= 50[/tex] and number of pensioner [tex]= 47[/tex].
What is number?" Number is defined as the count of the given quantity."
According to the question,
Total number of seats [tex]=100[/tex]
Total amount of full seats [tex]= \£100[/tex]
Price of adult ticket [tex]= \£ 3.50[/tex]
Price of children ticket [tex]= \£ .85[/tex]
Price of adult ticket [tex]= \£ 1[/tex]
[tex]'x'[/tex]represents the number of adults
[tex]'y'[/tex] reprsents the number of children
[tex]'z'[/tex] represents the number of pensioner
As per given condition we have,
[tex]x + y + z = 100\\\\\£3.50x + \£0.85y + \£1z = \£ 100[/tex]
Using trial and error method we get,
[tex]x = 3 ,\\\\y= 50\\\\z= 47[/tex]
For total number of tickets
[tex]3 + 50 + 47 = 100[/tex]
Left hand side = Right hand side
Substitute in left hand side of total cost we get,
[tex]\£3.50(3) + \£0.85(50) + \£1(47) \\\\= \£10.50 + \£42.50 + \£47[/tex]
[tex]= \£ 100[/tex]
= Right hand side
Hence, as per the given data number of adults [tex]=3[/tex] , number of children [tex]= 50[/tex] and number of pensioner [tex]= 47[/tex].

b- 24
c- 4
d- 13
Answers
Final answer:
This answer explains how to calculate the Mean Absolute Deviation (MAD) for a given data set and determines the MAD for the provided set of numbers.
Explanation:
Mean Absolute Deviation (MAD) measures the average difference between each data point and the mean of the data set.
To calculate MAD:
Find the mean of the data set: (68 + 72 + 77 + 64 + 69 + 76) / 6 = 72.67
Find the absolute difference for each data point: |68 - 72.67|, |72 - 72.67|, |77 - 72.67|, |64 - 72.67|, |69 - 72.67|, |76 - 72.67|
Add up all the absolute differences and divide by the total number of data points: (4.67 + 0.67 + 4.33 + 8.67 + 3.67 + 3.33) / 6 = 4.67
The Mean Absolute Deviation for the given data set is 4.67. Therefore, option c- 4 is the correct answer.

Using synthetic division suffices to answer your question:
Step-by-step explanation:
Synthetic division is the process by one reduces a large polynomial in your case [tex]x^3-7x-6[/tex] by a binomial in your case [tex](x+1)[/tex].
To do so one does the following:
[tex]\begin{array}{cccccc}-1|& 1&0&-7&-6\\ & &-1&1&6 \\& 1&-1&-6&0 \end{array}[/tex]
Since we divided by a linear binomial it reduces the power by one which produces the following quadratic:
[tex](x^2-x-6)[/tex]
Which can be factored in the following, and I will provide the complete factorization as well:
[tex]p(x)=(x+1)(x-3)(x+2)[/tex]

2. What is the slope for section "c" of Mrs Washington's commute?
3. Explain the difference in "b" and "c" in context of Mrs. Washing driving home.
4. How far does Mrs. Washington live from her work?
Answers
Answer:
1. -1
2. -1/4
3. As the line nears closer to y = 0, Mrs. Washington is getting closer to her house. As such, the line represents miles driven per minute, representing speed. As the slope of the line becomes steeper, as it does during section B of the commute, Mrs. Washington is driving one mile per minute, or 60 miles per hour. As she drives through section C, she only drove 1 mile after 4 minutes, or 15 miles per hour.
4. She lives 20 miles from her office.
Step-by-step explanation:
1. You can find the slope for section B of the commute by taking two points in section B and using them to find the slope.
I will take (10, 13) and (14, 9) as my points.
You can use [tex]\frac{y2-y1}{x2-x1}[/tex] to find the slope:
[tex]\frac{13-9}{10-14} \\\\\frac{4}{-4}[/tex]
The slope for section b is -1.
2. You can find the slope for section C using the same method.
I will use the points (16, 7) and (20, 6):
[tex]\frac{7-6}{16-20} \\\\\frac{1}{-4}[/tex]
The slope for section c is -1/4.
3. As the line nears closer to y = 0, Mrs. Washington is getting closer to her house. As such, the line represents miles driven per minute, representing speed. As the slope of the line becomes steeper, as it does during section B of the commute, Mrs. Washington is driving one mile per minute, or 60 miles per hour. As she drives through section C, she only drove 1 mile after 4 minutes, or 15 miles per hour.
4. She lives 20 miles from her office. This is stated in the question itself.
Answer:
1. Speed = 1 mph
2. ¼ mph
3. She's driving at 4 times faster speed in b than c
4. 20 miles
Step-by-step explanation:
1. Slope of a distance time graph is the speed
(15-7)/(16-8)
8/8
1 mph
2. Speed = (7-6)/(20-16)
1/4 mph
3. Speed in b is greater than c
1 = 4(¼)
4. Distance from 20 to 0, is 20 miles

HELP PLZ I DONT GET THIS AGT ALL I SUCK AT MATH :( I REALLY NEED HELP CAN SOMEONE HELP PLZ
Answers
Answer:
£94
Step-by-step explanation:
Basically, we want to find the surface area of this cylinder.
The surface area of a cylinder is denoted by: A = 2πr² + 2πrh, where r is the radius and h is the height. However, note that the farmer only wants to paint the curved surface of the cylinder, so we don't want to include the 2πr² part that accounts for the two circular bases. Instead, we actually just want to find the value of 2πrh.
Here, we see that the diameter is 8 metres, so since the radius is half the diameter, we know that r = 8/2 = 4 metres.
We also see that the height is 6 metres, so h = 6.
Plug these numbers in:
2πrh
2π * 4 * 6 = 48π ≈ 150.8 m²
We see that each can of paint will cover 20 m², so divide 150.8 by 20 to find the number of cans we need:
150.8 ÷ 20 = 7.5 ≈ 8 cans
Each can costs £11.75, so multiply 8 by 11.75 to get the total cost:
11.75 * 8 = £94
The answer is £94.

Answers
Answer:
The answer is 5.
Step-by-step explanation:
Multiplicative rate of change can be described as the rate change based on a original amount or point.
If we look at the given points for the function f(x) = 2.5x, we can see that the x coordinates increase by one while the y coordinate is increasing by 5 times it's value for the previous point.
So we can say that the multiplicative rate of change is 5 for the function f(x) = 2.5x.

Answer: 119
Step-by-step explanation: got it right
In the given figure, measure of angle A is 61°, measure of angle B is 119° and measure of angle C is 62°.
From the given triangle triangle, exterior angle to the angle C is 118°.
We know that, sum of two adjacent angles is 180°.
Here, ∠C+118°=180°
∠C=180°-118°
∠C=62°
By using exterior angle theorem of triangle, we get
∠A+57°=118°
∠A=118°-57°
∠A=61°
So, ∠A+∠B=180° (Adjacent angles)
61°+∠B=180°
∠B=180°-61°
∠B=119°
Therefore, in the given figure, measure of angle A is 61°, measure of angle B is 119° and measure of angle C is 62°.
