If the circumference of a circle is 82p , then the value of ‘r’ is
(i) 41 cm
(ii) 82 cm
(iii) 21 cm
(iv) 20 cm
Answer:
41cm
Step-by-step explanation:
The circumference of a circle is 82π
Therefore r can be calculated as follows
2 × π × r= 82× π
2πr= 82π
r = 82π/2π
r= 41
Hence r is 41cm
Solve the system using substitution.

850 liters of walcr was shared cqually among 5 aquariums.
Ilow many liters of water does each aquarium have?
Each aquarium has 170 liters of water in it.
Step-by-step explanation:

find the distance of a cord 8cm from the centre of a circle of a radius 5 cm
Answer:
d = 3 cm
Step-by-step explanation:
Given that,
The distance of a cord, c = 8 cm
The radius of the circle, r = 5 cm
Half of the cord = 4 cm
We need to find the distance of a cord from the centre of the circle. We can find it using Pythagoras theorem,
[tex]5^2=d^2+4^2\\\\d^2=25-16\\\\d=3\ cm[/tex]
So, the required distance is 3 cm.

Nathan is making chocolate chip cookies, the recipe calls for 2 cup chocolate chips and will make 4 dozen cookies. He increases the recipe to make 6 dozen cookies and will need 3 cups chocolate chips. Find the constant of proportionality
Answer:
1/2
Step-by-step explanation:
Nathan is making chocolate chip cookies, the recipe calls for 2 cup chocolate chips and will make 4 dozen cookies. He increases the recipe to make 6 dozen cookies and will need 3 cups chocolate chips. Find the constant of proportionality
From the above question, we can see that the Number of Chocolate chips is directly proportional to the number of Dozen cookies
Hence:
C = Chocolate chips
D = Dozen cookies
Hence:
C ∝ D
C = kD
Where k = Constant of Proportionality.
We are told that , the recipe calls for 2 cup chocolate chips and will make 4 dozen cookies.
Hence:
2 = 4k
k = 2/4
k = 1/2
Also, He increases the recipe to make 6 dozen cookies and will need 3 cups chocolate chips.
3 = 6k
k = 3/6
k = 1/2
Therefore, from the calculations above, the constant of proportionality is 1/2

Please help me in this
The answer is A. 2 and 4
Reason:
To formula for circumference is 2 x r x pi
2 x 2 = 4, 2 x 4 = 8and 4 + 8 = 12
Area is r ^2 x pi
2 ^2 = 4, 4^2 = 16 and 4 + 16 = 20
the question is "get y by itself" and the equation is 5x + 5y =15
Answer:
y=3-x
Step-by-step explanation:
Answer:
First we get y on one side by itself.
5x+5y=15
We move x over to the other side.
5x-5x+5y=15-5x
Simplify.
5y=15-5x
Now we remove the coefficient from y.
5y/5=(15-5x)/5
Simplify.
y=15/5-5x/5
y=3-x
The answer is y=3-x
The grocery store had 4lb bag of oranges for 4.80$ and a 6lb bag for 6.18$ . What is the difference of the 4lb bag of oranges and the 6lb bag of oranges
Answer:
$1.38
Step-by-step explanation:
The grocery store had 4lb bag of oranges for 4.80$ and a 6lb bag for 6.18$ . What is the difference of the 4lb bag of oranges and the 6lb bag of oranges
The cost difference is calculated as:
Cost of 6lbs of oranges - Cost of 4lbs of oranges
Cost of 6lbs of oranges = $6.18
Cost of 4lbs of oranges = $4.80
Hence,
= $6.18 - $4.80
= $1.38
Of the 10 clients who had their hair cut at Sue's salon last month, 5 had blond hair. Considering this data, how many of the next 14 clients to get haircuts should you expect to have blond hair?
Answer: 7 clients
Step-by-step explanation:
Of the last 10 clients that cut their hair at the salon, 5 had blond hair.
That is a proportion of:
= 5 / 10
= 1/2
Assuming this same proportion applies to the next clients Sue gets, the expected number of blonde people will be:
= Number of clients * 1/2
= 14 * 1/2
= 7 clients
