On a certain hot summer's day, 196 people used the public swimming pool. The daily prices are $ 1.50 for children and $ 2.00 for adults. The receipts for admission totaled $ 314.00 . How many children and how many adults swam at the public pool that day?
Number of adults = 40
Number of children = 156
Step-by-step explanation:
Let x be the number of adults and
y be the number of children
Then according to given statements
[tex]x+y=196\ \ \ Eqn\ 1\\2.0x+1.50y = 314\ \ \ Eqn\ 2\\[/tex]
From equation 1:
[tex]x+y = 196\\x = 196-y[/tex]
Putting in equation 2
[tex]2(196-y) + 1.50y = 314\\392-2y+1.50y = 314\\392-0.5y = 314\\-0.5y=314-392\\-0.5y=-78[/tex]
Dividing both sides by -0.5
[tex]\frac{-0.5y}{-0.5} = \frac{-78}{-0.5}\\y = 156[/tex]
Putting y = 156 in equation 1
[tex]x+156 = 196\\x = 196 - 156\\x = 40[/tex]
Hence,
Number of adults = 40
Number of children = 156

If Carrie and Cory add on 18% tip to the bill after tax what does their lunch cost in total
Answer:
The cost of total lunch is 1.18 y ( 1+ 0.0 x )
Step-by-step explanation:
Given as :
The percentage of tip added tot he bill after tax = 18 %
Let the tax added to the bill = x % of total the lunch price
Let The total lunch cost = y
So, The cost of the lunch after tax = y + x % × y
I.e The cost of lunch after tax = y × ( 1 +x % )
Or. The bill of lunch after tax = y × ( 1 + 0.0 x )
Now the cost of lunch after tax and tip =18 % of y × ( 1 + 0.0 x ) + y × ( 1 + 0.0 x )
Or, the cost of lunch after tax and tip = y × ( 1 + 0.0 x ) (0.18 + 1 )
∴ The cost of lunch after tax and tip = y × ( 1 + 0.0 x ) × 1.18
Hence The cost of total lunch is 1.18 y ( 1+ 0.0 x ) Answer

I am joyous to assist you anytime.
The name of a 21 sided polygon is Henicosagon.
What is a polygon?A polygon is a plane figure made up of line segments connected to form a closed polygonal chain. The segments of a closed polygonal chain are called its edges or sides. The points where two edges meet are the polygon's vertices or corners. The interior of a solid polygon is its body.
Given that, what is the name of a 21 sided polygon,
Polygons have very simple names for the first twenty names.
They use a basic prefix naming system. Di, tri, tetra, penta, and so on.
But polygons with 21 to 99 sides have a different naming system.
First, we use a prefix for the tens (such as triaconta—30). Then we use a prefix for the ones (such as di—20).
At last, we put them together with a ‘kai’ between them. This would be formatted to look like (tens)kai(ones)gon.
In simpler words, a 32-sided polygon. We can normally refer to it as a 32-gon.
Hence, the name of a 21 sided polygon is Henicosagon.

32
. The third integer is 15

less than the first. Find the three integers.
The three integers are 5,17 and -10
Step-by-step explanation:
Let x, y and z be three integers then
[tex]x+y+z=12 \ \ \Eqn\ 1[/tex]
'The sum of the first and second integers exceeds the third by 32'
[tex]x+y=z+32\ \ \ \ Eqn\ 2[/tex]
The third integer is 15 less than the first.
[tex]z=x-15\ \ \ \ Eqn\ 3[/tex]
From Eqn 2:
[tex]x+y=z + 32\\x+y-z=32[/tex]
Subtracting Eqn 1 from eqn 2
[tex]x+y-z-(x+y+z)=32-12\\x+y-z-x-y-z=20\\-2z=20[/tex]
Dividing both sides by -2
[tex]\frac{-2z}{-2}=\frac{20}{-2}\\z=-10[/tex]
Putting z=-10 in Eqn 3
[tex]z=x-15\\-10=x-15\\x=15-10\\x=5[/tex]
Putting x=5 and z=-10 in Eqn 1
[tex]x+y+z=12\\5+y-10=12\\y-5=12\\y=12+5\\y=17\\[/tex]

Answer:
First = 5, second = 17, third = -10
Step-by-step explanation:
First integer = x
The third integer is 15 less than the first, so
Third integer = x - 15
The second integer = y
The sum of the first and second integers exceeds the third by 32, so
The sum of the first and second integers = x + y
The third integer = x - 15
x + y is 32 more than x - 15, hence
x + y - 32 = x - 15
y - 32 = -15
y = 32 - 15
y = 17
The second integer = 17
The sum of three integers is 12, so
x + 17 + x - 15 = 12
2x + 2 = 12
2x = 12 - 2
2x = 10
x = 5
x - 15 = 5 - 15 = -10
Write the equation of the line that passes through the point (4,3) and is perpendicular to the line y=2x-4
Answer:
y-3=-1/2(x-4)
Step-by-step explanation:
y-y1=m(x-x1)
perpendicular means negative reciprocal of the current slope,
and the negative reciprocal of 2 is -1/2.
y-3=-1/2(x-4)
what is the equation of a line parallel to y-2x=3 that passes through the point (3,1)
Answer:
y = 2x - 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Rearrange y - 2x = 3 into this form by adding 2x to both sides
y = 2x + 3 ← in slope- intercept form
with slope m = 2
Parallel lines have equal slopes, thus
y = 2x + c ← is the partial equation
To find c substitute (3, 1) into the partial equation
1 = 6 + c ⇒ c = 1 - 6 = - 5
y = 2x - 5 ← equation of line
a woman is walking at the rate of 90 yards per minute. How fast is she going in feet per second?
Answer:
She is going at the rate of 4.5 feet per second.
Step-by-step explanation:
Given:
The rate of walking is 90 yards per minute.
Now, to find the rate in feet per second.
1 yard = 3 foot.
1 minute = 60 seconds.
So, first we find the rate of walking per second in yard = [tex]90\div 60[/tex]
Therefore by dividing we get = [tex]1.5 yard[/tex]
Now, we find the rate of walking per second in feet = [tex]1.5\times 3[/tex]
So, by multiplying we get = [tex]4.5 feet[/tex]
Therefore, she is going at the rate of 4.5 feet per second.
A book has 150 pages and you read 3 pages per day.after a certain number of days,there are 60 pages left.write an equation to show how many days,x,you read
To determine the number of days you have read, an equation is set up as 150 - 3x = 60, where x represents the number of days. After solving, it reveals that you have read for 30 days.
Explanation:To find the number of days, x, that you have read, given that there are 60 pages left and you read 3 pages per day in a 150-page book, we can set up the following equation:
150 - 3x = 60
This equation represents the total number of pages in the book (150) minus 3 pages for each day that you read (3x) equal to the number of pages left (60).
Now, solve for x to determine the number of days you have been reading:
150 - 60 = 3x
90 = 3x
x = 30 days
Therefore, you have been reading for 30 days.
Solve for x.
