At a zoo, the lion pen has a ring-shaped sidewalk around it. The outer edge of the sidewalk is a circle with a radius of 12 m. The inner edge of the sidewalk is a circle with a radius of 8 m.
Write and simplify an expression for the exact area of the sidewalk.
Find the approximate area of the sidewalk. Use 3.14 to approximate π.
Answers
Answer:
The answer would be 251.2 for the side walk if the radius for the whole circle is 12 and the small circle's radius would be 8. Only for the answer with the 8 m and 12 m radius NOT the 11m and 9 m
The equation would be:
144 x 3.14 - 64 x 3.14 = 251.2
Step-by-step explanation:
First, you need to find out what the whole circle is:
The whole circle is 452.16
Then, find the inner circle :
8 x 8 x 3.14
200.96
Last, subtract the whole by the inner:
452.16 - 200.96 = 251.2

Write a real word problem that involves dividing a decimal by a whole number

This question would mean dividing 75% or .75 by 3 which would mean each person got 25% or .25 of what would be a whole pizza.
So while each person would get .33 of the current sized pizza (.75) in terms of a whole pizza it would be .25

On a certain hot summer day, 673 people used the public swimming pool. The daily prices are 1.75 for children and 2.00 for adults.The receipts for admission totaled to $1249.50. How many children and how many adults swam at the public pool that day?
Answers
Answer:
120 children and 388 adults bought tickets for the swimming pool
Explanation:
Create two simultanous equations:
Let c stand for the number of children that bought a ticket, and a stand for the number of adults that bought a ticket, you get your first equation, being
c
+
a
=
508
then, you now create a second equation for the prices of the tickets.
(price of childrens tickets)(number of children that swam)+(price of adults tickets)(number of adults that swam) = total money collected
so:
1.75
c
+
2.25
a
=
1083.00
now we still know, that
a
=
508
−
c
so we can substitute it into the second formula
1.75
c
+
2.25
(
508
−
c
)
=
1083
now its just simple algebra
1.75
c
+
1143
−
2.25
c
=
1083
60
=
0.5
c
so:
c
=
120
now we know, that 120 children went to the swimming pool.
and we still have the formula from before:
a
=
508
−
c
so
a
=
388
The line 1 has equation 5x + 6y + 30 = 0. Given
that P is the point (3, -1), find
(i) the coordinates of the point where l crosses the
x-axis,
(ii) the coordinates of the point of intersection
of l with the line x = 2,
(iii) the equation of the line passing through P
and having the same gradient as I,
(iv) the equation of the line passing through P
and having a gradient of 0.
w through the points ACO 3).
Answers
Answer:
Step-by-step explanation:
i) the x-intercept is when y=0
5x+6(0)+30=0
5x=-30
x=-6
hence the point is (-6,0)
ii)5(2)+6y+30=0
10+6y+30=0
6y=-40
y=-20/3
hence the point of intersection is (2,-20/3)
iii) y+1=-5/6(x-3)
6y+6=-5x+15
6y+5x=9
iv) y+1=0(x-3)

at a certain college, the ratio of men to women is 6 to 5. If there are 1,500 men how many women are there?
Answers
Answer:
1250 women
Step-by-step explanation:
1500 / 6 = 250
250 x 5 = 1250
hope this helps
Answer:
There are 1,250 women
Step-by-step explanation:
If the ratio of men to women is 6 to 5, and there are 1,500 men, the actual ratio of men to women is 1,500 to x, where x is equal to the amount of women at the college.
Since 6/5 is equal to 1,500/x, you cross multiply to find that 7,500 is eual to 6x.
Divide both sides by 6 to find that x is equal to 1,250 women.

A cylindrical container has a diameter of 5 inches and a height of 12 inches. The container will be wrapped and delivered as a gift. What measurement is closest to the amount of wrapping paper needed to cover the container without overlap?
Answers
Answer:
Step-by-step explanation:
1. Write your formula
2. Plug it in
3. Solve
these steps will help you out with all of your surface area problems.
Like this
Since it is a diameter you have to divide the diameter by 2. That will get you your radius. Then you write your formula for a cylinder. Your formula is...
V = Bh (Pie is also known as 3.14)
your big (B) is (pie times r squared) Then you add your height.
so your formula will look like this...
V = pie times r squared...
the full formula will be...
V = (3.14) times (2.5 squared) times the height which in this case is (12)
everything together will be...
V = (3.14) (2.5^2) (12)
all you have to do is multiply all of that and you will get your answer.
The answer is...
V = 236 inches ^2 (Just a tip, the ^ sign means to the power of)
