On a certain hot summers day 339 people used the public swimming pool. The daily prices are $1.75 for children and $2.50 for adults. The receipts for admissions totaled $750.50. How many children and how many adults swam at the public pool that day?
Answer:
the number of children = 156
the number of adults = 183
Step-by-step explanation:
let x be the number of children
y be the number of adults
We have to solve this system:
[tex]\begin{cases}x+y=339&\\ 1.75x + 2.50y = 730.50&\end{cases}[/tex]
[tex]\Longleftrightarrow \begin{cases}y=339-x&\\ 1.75x + 2.50(339-x) = 730.50&\end{cases}[/tex]
[tex]\Longleftrightarrow \begin{cases}y=339-x&\\ -0.75x + 847.5 = 730.50&\end{cases}[/tex]
[tex]\Longleftrightarrow \begin{cases}y=339-x&\\ -0.75x =-117&\end{cases}[/tex]
[tex]\Longleftrightarrow \begin{cases}y=339-156=183&\\ x =156&\end{cases}[/tex]

Based on meteorological records, the probability that it will snow in a certain town on January 1st is 0.315. Find the probability that in a given year it will not snow on January 1st in that tow
The probability that in a given year it will not snow on January 1st will be P = 0.915.
What is probability?Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Since the total probability is always equal to 1 if the probability of happening of an event is given then the probability of not happening of an event will be determined by subtracting it from one.
The probability of not any snowfall will be calculated as:-
P = 1 - 0.315
P = 0.615
Therefore the probability that in a given year it will not snow on January 1st will be P = 0.915.

The title of this graph shown in the image attached below is "Number of Kg. of rice donated for Typhoon Roly's victim."
The title of the graph.Generally, the title of a graph is typically placed at the top. Based on the information provided in the graph (see attachment), the title of this graph is "Number of Kg. of rice donated for Typhoon Roly's victim."
What kind of graph is shown?In this scenario, the kind of graph shown is referred to as a bar graph.
A family with the most number of kilograms of rice donated is the "Carlage family" because their data has the tallest rectangular bar, which corresponds with 150 kg.
A family with the least number of kilograms of rice donated is the "Dioneda family" because their data has the shortest rectangular bar, which is equal to 75 kg.
The total number of kilograms of rice donated is given by:
Total number = 150 + 100 + 175 + 120 + 100

Answer:
1) 13,434
2) During 2038 (by 2039)
Step-by-step explanation:
We can model this problem using an exponential equation.
General form of an exponential equation: [tex]y=ab^x[/tex]
where:
a is the initial value b is the base (or growth factor) in decimal formx is the independent variabley is the dependent variableIf b > 1 then it is an increasing function
If 0 < b < 1 then it is a decreasing function
As the population increases by 3% each year, each year it will be 103% of the previous year. Therefore, the growth factor in decimal form is 1.03
Given:
a = 8,888b = 1.03 x = time (in years)y = populationSubstituting the given values into the equation:
[tex]y=8888(1.03)^x[/tex]
To find the population in 2025:
2025 - 2011 = 14
Therefore, set x = 14 and solve for y:
[tex]\begin{aligned}\implies y &=8888(1.03)^{14}\\& =13433.89747\\& = 13,434\end{aligned}[/tex]
To find the year in which the population will reach 20000, set y = 20000 and solve for x:
[tex]\implies 8888(1.03)^x=20000[/tex]
[tex]\implies (1.03)^x=\dfrac{20000}{8888}[/tex]
[tex]\implies \ln (1.03)^x=\ln \left(\dfrac{20000}{8888}\right)[/tex]
[tex]\implies x\ln (1.03)=\ln \left(\dfrac{20000}{8888}\right)[/tex]
[tex]\implies x=\dfrac{\ln \left(\frac{20000}{8888}\right)}{\ln (1.03)}[/tex]
[tex]\implies x=27.43785809[/tex]
2011 + 27.437... = 2038.437...
Therefore, the population will reach 20,000 some time during 2038.
Students in a school were asked to collect old bottles as part of a recycling drive. Some of the data recorded at the drive is shown in the histogram below:
Which information is not provided in the histogram?
The total number of students who collected bottles
The number of students who collected exactly 9 bottles
The number of students who collected 3 or fewer bottles
The total number of students who collected 7 or fewer bottles
Answer:
The number of students who collected exactly 9 bottles.
Step-by-step explanation:
The given histogram shows the number of students who participated in the recyling drive & their old bottle waste collection.
We can find out the total number of students who participated just by looking at the histogram (students = 10), the number of students who colected bottles below 7 or 3 bottles etc.
But since the number of bottles is given in the form of grouped data, one cannot infer the exact number of bottles collected by students.
Hence, out of the given statements, 'The number of students who collected exactly 9 bottles' is the incorrect one.

Determine the
period.
Explanation:
There are a few ways to measure the period. One way is to measure the horizontal distance from peak to peak.
The left peak occurs at x = 1
The right peak occurs at x = 17
This is a horizontal distance of 17-1 = 16 units.
Therefore, the period is 16. The curve repeats itself every 16 units.
6/6 = 8/8 because they both equal 1. Oleg adds one part to each. Will the results be equal?
Use the drop-down menus to complete an explanation.
Rewrite the fractions as decimals:
7/6 = 1.167
9/8 = 1.125
7/6 is greater then 9/8
the parts in 7/6 are greater than the parts in 9/8
so 7/6 is farther from 1 than 9/8 is
Give an example of a binomial of degree 27
Answer:
x27 + y.
Step-by-step explanation:
Binomial means having 2 terms so binomial of degree 27 is x^27 + y type.
For example,
x^27+y+2
If there are 2 degree terms of x, degree of the one having highest degree is taken.
For example,
In x^27+x^10
As highest degree is 27, this is a binomial of degree 27.

Answer:
3. 261 ft³
Step-by-step explanation:
Volume of the figure = ½(volume of cylinder) + volume of triangular prism)
✔️Volume of cylinder = πr²h
r = 3 ft
h = 10 ft
Volume of cylinder = π*3²*10 = 282.74 ft³
✔️Volume of right triangular prism = ½*b*h*l
b = 3*2 = 6 ft
h = 4 ft
l = 10 ft
Volume of triangular prism = ½*6*4*10 = 120 ft³
✔️Plug in the values into the equation:
Volume of the figure = ½(282.74) + 120 = 261.37 ≈ 261 ft³

Volume=
Step-by-step explanation:
Volume of cylinder = π.r^2.h
h = 5 inch, r = 6 inch, π = 3.14
==> Volume = (3.14)×(6×6)×(5)
==> Volume = 565.2 inch^3
Hence the volume of cylinder is 565.2 cubic inches.
