Answer:
A
Step-by-step explanation:
Total amount of extra money needed to be raised
= $483.62 -$218.25
= $265.37
Since each student raises the same amount and there are 17 students, $265.37 would be shared equally amongst the 17 students.
Amount of money each student must raise
= $265.37 ÷17
= $15.61
There are two similar triangles in the diagram. Find the unknown measurement.
Answer: x=180
Step-by-step explanation:
360/120=x/60
3=x/60
x=180
By the similarity of triangles the length of the side RS is 180 units.
What is a triangle?A triangle is a three-sided closed-plane figure formed by joining three noncolinear points. Based on the side property triangles are of three types they are Equilateral triangle, Scalene triangle, and Isosceles triangle.
We know in similar triangles the ratio of their corresponding sides are equal.
Given, Are two triangles OPQ and ORS.
Therefore,
OP/PR = PQ/RS.
120/360 = 60/x.
120x = 21600.
12x = 2160.
x = 2160/12.
x = 180.

At what rate, in gallons per hour, is the swimming pool being filled?
A. 15 gallons per hour
B. 4000 gallons per hour
C. 66.6 gallons per hour
D. 2000 gallons per hour
Answer: 4,000
Step-by-step explanation:
The solution is Option A.
The rate at which the swimming pool is being filled is 66.6 gallons per hour
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the number of gallons be = y
Let the time taken be = x
The total volume of the pool = 15000 gallons
The pool is filled at constant rate
Now ,
The coordinate data is given as
The value of A = A ( 15 , 1000 )
The value of B = B ( 30 , 2000 )
The value of C = C ( 45 , 3000 )
Now , the rate at which the swimming pool is filled is given by the slope of the points in the line
So , the slope of the 2 points is given by the formula
Slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 2000 - 1000 ) / ( 30 - 15 )
On simplifying the equation , we get
Slope m = 1000 / 15
Slope m = 66.66 gallons per hour
Therefore , the value of A is 66.6 gallons per hour
Hence ,
The rate at which the swimming pool is being filled is given by the slope of the line where slope m = 66.6 gallons per hour

in the graph shown below, if lines 1^1 are parallel, then the slope of the line 1^2 is?
Answer:
Two lines are parallel if the have the same slope. Example 1: Find the slope of the line parallel to the line 4x – 5y = 12. To find the slope of this line we need to get the line into slope-intercept form (y = mx + b), which means we need to solve for y: The slope of the line 4x – 5y = 12 is m = 4/5.Step-by-step explanation:
good morningIf the lines l1 and l2 are parallel, then the slope of line l2 is the same as the slope of line l1.
The slope-intercept definition of a linear function is given as follows:
y = mx + b.
For which the parameters are given as follows:
m is the slope, representing the rate of change of the function.
b is the intercept, representing the value of y when x = 0.
When two lines are parallel, they have the same slope.
Hence, If the lines l1 and l2 are parallel, then the slope of line l2 is the same as the slope of line l1.

The school cafeteria sells two kinds of wraps: vegetarian and chicken. The vegetarian wrap costs $1.00 and the chicken wrap costs $2.70. Today they made $119.60 from the 72 wraps sold. How many of the wraps sold were vegetarian
Answer:
vegetarians= 28
chickens= 44
Step-by-step explanation:
let the number of vegetarians be x
and chickens be y
So
x+2.7y=119.6----------1
x+y=72--------------2
from 2, x= 72-y
put x= 72-y in 1
72-y+2.7y=119.6
-y+2.7y=119.6-72
1.7y=47.6
divide both sides by 1.7
y=47.6/1.7
y=28
put y=28 in 1
x+28=72
y= 72-28
y=44
An initial population of 460 quail increases at an annual rate of 21%. Write an exponential function
to model the quail population. What will the approximate population be after 3 years?
Answer:
the expected population after 3 years is 863.7009
Step-by-step explanation:
The computation of the expected population after 3 years is shown below
P = P_0 × e^rt
where,
r = 21% = 0.21
t = 3 years
P_0 = 460
Now place these values to the above formula
P = 460 × exp(0.21 × 3)
= 863.7009
hence, the expected population after 3 years is 863.7009
We simply applied the above formula so that the correct value could come

Complete question :
At Alan's auto shop, it takes him 9 minutes to do an oil change and 12 minutes to do a tire change. Let x be the number of oil changes he does. Let y be the number of tire changes he does. Using the values and variables given, write an inequality describing how many oil changes and tire changes Alan can do in less than an hour ( minutes).
Answer:
9x + 12y < 120
Step-by-step explanation:
Given that:
Time taken for oil change = 9 minutes
Time taken for tire change = 12 minutes
x = number of oil changes ; y = number of tire changes
Total hours = 1 hour = 60 minutes
Number of oil and Tyre changes possible in less than an hour
(Number of oil changes * time taken) + (number of tire changes * time taken) less than 60 minutes

The graph shows the amount of money in Amy's bank account and her spending activity. Does the graph show a proportional relationship?
A. Yes, it is proportional because it has a constant rate of change.
B. No, it is not proportional because it has a constant rate of change.
C. Yes, it is proportional because it has a y-intercept.
D. No, it is not proportional because it has a y-intercept that is not zero.
Answer:
Option A:
Yes, it is proportional because it has a constant rate of change.
Step-by-step explanation:
One trick you can use to easily tell a proportional graph is that it follows a straight line. It does not matter whether the line slopes downwards or upwards. The fact that it is straight and not cured at any point, should hint you that the graph is proportional.
Proportional graphs have a constant rate of change. The value of the slope calculated when using any two (x, y) coordinates are the same for any point along the line.

Which of the following numbers are perfect . 3364,4489,4358 please solve
Answer:
Below
Step-by-step explanation:
A perfect number is one whose proper divisors add up to that number.
For example, 6 is a perfect number because
Its proper divisors 1, 2 and 3 and 1+2+3 = 6.
First list prime factors:
3364 = 2 * 2 * 29 * 29
Proper divisors are 1, 2, 4, 29, 58, 116, 841, 1682
Sum of these = 2733.
So, 3364 is not a perfect number.
4489 = 67 * 67
Divisors are 1 and 67.
Sum = 68.
So, 4489 is not a perfect number.
4358 =2 * 2179
Divisors are 1 , 2 and 2179.
Sum = 2182.
So, 4358 is not a perfect number.

Answer:
The three main types of geography are physical, environmental and human geography. There are other sub-branches of geography such as political geography, historical geography and religious geography.
Physical geography deals with the study of Earth and its structure. The landforms, continents, oceans and tectonic movements are a part of physical geography. The formation of rocks, weathering, forces of erosion, winds, ocean currents and rivers are all studied as a part of physical geography. Environment geography deals specifically with the study of the interaction of plants and animals with Earth. Human geography focuses on how human societies flourish with the help of natural resources. It deals with the study of the evolution of cultures and religious beliefs. Economic, cultural and political geography are sub-branches of human geography.
