Answer: 48 pupils get the bus to the cinema and 36 pupils walk to the cinema.
Step-by-step explanation:
Let's suppose that there are a total of N pupils.
We know that N/4 walk to the cinema.
We know that N/3 get the bus to the cinema.
And the remainder is equal to 60 people.
Then:
N - N/4 - N/3 = 60
N*(1 - 1/4 - 1/3) = 60
N( 12/12 - 3/12 - 4/12) = 60
N*( 5/12) = 60
N = (12/5)*60 = 144
Then the number of pupils that walk to the cinema is N/4, or:
144/4 = 36
And the number of pupils that get the bus is N/3, or:
144/3 = 48.

4 2/5+k=−3 2/11
Need help
Answer:
2/11
Step-by-step explanation:
Here we have two mixed numbers. Be very careful when handeling negative mixed numbers. Don't coonfuse "-3 2/11" with "-3 + 2/11"
4 2/5 + k = -3 2/11
I add a minus into the mixed fraction on the right. Of course you don't have to write an entire new line when you do calculations on paper.
4 2/5 + k = -3 -2/11
k = - 3 - 4 - 2/5 - 2/11
k= - 7 -2/5 -2/11
Make common denominators. Both 11 and 5 is prime numbers (numbers that are only divisible by one and itself). Therefore the common denominator is 5*11=55.
k= - (7*55)/55 - (2*11)/(5/11) - (2*5)/(11*5)
k = - 385/55 - 22/55 -10/55
k = - (385 +22+10)/55
k = - 417/55
Since 417 isn't divisible by neither 11 nor 5, this fraction is in it's simplest form.
btw correct me if i am wrong
Answer:
[tex] k = - 1 \frac{12}{55} [/tex]
Step-by-step explanation:
[tex]4 \frac{2}{5} + k = 3 \frac{2}{11} \\ \frac{22}{5} + k = \frac{35}{11} \\ k = \frac{35}{11} - \frac{22}{5} \\ k = \frac{175 - 242}{55} \\ k = \frac{ - 67}{55} \\ k = - 1 \frac{12}{55} [/tex]

Terry pays £480 per month in rent.
His landlord decides to increase the rent by 7.5%.
How much rent does he pay now?
Answer: £516
Step-by-step explanation:
7.5 increase = 100 + 7.5 = 107.5
107.5/100 = 1.075 (multiplier)
480 x 1.075 = 516
introduces a study where researchers studying the relationship between honesty, age, and self-control conducted an experiment on 1G0 children between the ages of 5 and 15. The researchers asked each child to toss a fair coin in private and to record the outcome (white or black) on a paper sheet, and said they would only reward children who report white. Half the students were explicitly told not to cheat and the others were not given any explicit instructions. Differences were observed in the cheating rates in the instruction and no instruction groups, as well as some differences across children's characteristics within each group. (a) Identify the population of interest and the sample in this study. (b) Comment on whether or not the results of the study can be generalized to the population, and if the findings of the study can be used to establish causal relationships.
Answer:
The solution to this question can be defined as follows:
Step-by-step explanation:
In choice a:
Both children between 5 and 15 years old and 160 years old are also the populations of interest, and Kids from 5 to 15 years of age.
In choice b:
These findings could be compared like we do not know whether the groups were randomly selected, and the allocation is still not random; there could be no casual conclusion because the statement is valid even With sample research, and after randomization, filtering, and testing of 160 specimens (instruction vs no-instruction) Its analysis can be common to the community and replicated. There could be explanatory relations generated by experimental research. This analysis is observational and can therefore be used Causal relationships are established.gggg

Answer:
its 3 the answer is 3.
Step-by-step explanation:
because I did this before thank you ,its 3.
Answer:
Three fifths
Step-by-step explanation:
Since 10 was divided by 2 to get 5,
you just do the same to the top half of the fraction.
So when you divide 6 by 2, you get 3.
So it is equal to 3/5, or three fifths.
And 3/5 is equivalent to 6/10

Approximate: log5 ^4/7
Answer:
log5 (4/7)= log5 (4)- log5 (7)=-0.347708839
Step-by-step explanation:
for the first question which would be Approximate: log5 4/7 the answer would be B. –0.3477
and for the second question which would be Approximate: log1/2 5 the answer would be C.–2.3219
Step-by-step explanation: Using Properties of Logs
logb(x/y) = logbx - logby.
Furthermore
log5 (4/7)= log5 (4)- log5 (7)
Solve log 5 (4) and log 5 (7) with the base change of the logarithm
log 5 4 = log 4 / log 5
Use the calculator (DESMOS): log 5 4 =0.8613531161
log 5 7 = log 7 / log 5
log 5 7 =1.2090619551
Therefore, The answer is, log5 (4/7)= log5 (4)- log5 (7)=-0.347708839
For the second part of the question just to not make this too long the answer to the second part is: C ( -2.3219 )

For every 1 litre of water used 150ml of sucrose and 600ml of saline solution is used
Question:
For every 1 litre of water used to make a medicine, 600 ml of sucrose and 150ml of saline solution are used.
Express the amount of water, sucrose and saline solution needed as a ratio in its simplest form.
Answer:
[tex]Water : Sucrose : Saline = 20 : 3 : 12[/tex]
Step-by-step explanation:
Given
[tex]Water = 1L[/tex]
[tex]Sucrose = 150mL[/tex]
[tex]Saline= 600mL[/tex]
Required
Express as a ratio to the simplest form
First convert the volume of water to mL
[tex]Water = 1L[/tex]
[tex]Water = 1 * 1000mL[/tex]
[tex]Water = 1000mL[/tex]
Express as ratio:
[tex]Water : Sucrose : Saline = 1000mL : 150mL : 600mL[/tex]
[tex]Water : Sucrose : Saline = 1000 : 150 : 600[/tex]
Divide through by 10
[tex]Water : Sucrose : Saline = 100 : 15 : 60[/tex]
Divide through by 5
[tex]Water : Sucrose : Saline = 20 : 3 : 12[/tex]
The ratio can not be further simplified

A store is having a 20% off sale on all merchandise 1. If Mai buys one item and saves $13 what was the original price
Answer: $65
Step-by-step explanation:
The store is having a 20% off sale.
Mai buys an item and saves $13.
This means that $13 is 20% of the price of the item that Mai bought.
Assume the original price is x. Expression is:
x * 20% = 13
x = 13/20%
x = $65

Find the y-intercept of the line on the graph.
Enter the correct answer
Given:
The graph of a line.
To find:
The y-intercept of the line.
Solution:
y-intercept of a line is the point at which the line intersect the y-axis.
We have, graph of the line.
From the given graph it is clear that the line intersect the y-axis at (0,4).
So, y-intercept is at point (0,4).
y-intercept = 4
Therefore, the y-intercept is 4.

You have budgeted $4,800 for a company to complete guest satisfaction surveys for you. They charge $1,800 + $6 per respondent. How many respondents will you be able receive for the money paid?
Answer:
6
Step-by-step explanation:
There are 500 respondents will you be able receive for the money paid.
What is mean by expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The budgeted for a company to complete guest satisfaction surveys for you is, $4,800.
And, They charge $1,800 + $6 per respondent.
Now,
Let Number of respondents will you be able receive for the money paid is, x
Hence, We can formulate;
⇒ $1800 + $6x = $4800
⇒ 1800 + 6x = 4800
⇒ 6x = 4800 - 1800
⇒ 6x = 3000
⇒ x = 500
Thus, There are 500 respondents will you be able receive for the money paid.
