Circle A has a radius of 9 centimeters and Circle B has a diameter of 19 centimeters. What is the relationship between the circumferences of Circle A and Circle B?
Answer:
18:19
Step-by-step explanation:
Given that,
The radius of circle A = 9 cm
The diameter of circle B = 19 cm
We know that,
Radius = diameter/2
The radius of circle B = 19/2 cm
The circumference of circle A is :
[tex]C_A=2\pi r_A[/tex] ....(1)
And that of circle B is :
[tex]C_B=2\pi r_B[/tex] ....(2)
Dividing equation (1) and (2) :
[tex]\dfrac{C_A}{C_B}=\dfrac{2\pi r_A}{2\pi r_B}\\\\=\dfrac{r_A}{r_B}\\\\=\dfrac{9}{\dfrac{19}{2}}\\\\\dfrac{C_A}{C_B}=\dfrac{18}{19}[/tex]
Hence, the ratio of circumferences of Circle A and Circle B is 18:19.

HELP ASAP
Answer: 20
Step-by-step explanation: 3 feet in 1 yard, there are 6 yards.
6 x 3 = 18 feet plus the 2 extra = 20 feet
Factor 6x + 30 to identify equivalent expressions. Select all that are equivalent expressions.
2(3x + 15)
6(x + 30)

1. Solve for q:
√3q + 2 = √5
2. solve for d:
4d + 1 = √3
3. Solve for m:
m/√3 - 11 = 4
Answer:
1) q = (sq rt 15 - 2) / 3
2) d = (sq rt 3 - 1) / 4
3) m = 15 * sq rt 3
Step-by-step explanation:
1.√3q + 2 = √5
we bring to the power of 2 each element
(√3q)^2+2^2=√5^2
3q+4=5
3q=4-5
q=1/3
2.
4d+1=√3
we do the same thing
16d^2+1=3
16d^2=2
d^2=2/16
d^2=1/8
d=√1/√8
3.
m/√3 -11=4
first we rationalise by multiplying the first fraction with √3
m√3 /3-11=4
now we can bring to the power of 2
3m^2/9-121=16
3m^2/9=137
m^2/3=137
m^2=411
m=√411

A scholar surveyed educators to determine if there was correlation between age and holding a doctorate degree. The survey results are below: Have a doctorate Do not have a doctorate 30 or younger 10 25 Older than 30 14 22 How many educators have a doctorate and are older than 30?
Answer:
14
Step-by-step explanation:
Given the result :
______________Doctorate ___ No doctorate
30 or younger ___ 10 ___________ 25
Older than 30 ___ 14 ___________ 22
Number of educators who have a doctorate and older than 30 = 14 ( from the table)
Older than 30 n Doctorate = 14

Can someone tell me which are non linear and which are linear for these three ? Ill give brainliest asap
Answer:
The y-value sequence on 1 linear. The x-value sequence on 1 is also linear.
The y- value sequence on 2 is linear. The x-value sequence on 2 is also linear.
The y-value sequence on 3 is linear. However I now think you are referring to the domain and range also linear graphs and non linear graphs, maybe I've confused you.
Step-by-step explanation:
So the difference between an exponential function and a linear function is whether it is arithmetic sequence or geometric sequence or just another sequence.
arithmetic is if the numbers are added by the common difference.
geometric is if the numbers are multiplied by the common ratio.

Examine whether x + 2 is a factor of x³ + 3x² + 5x + 6 and of 2x + 4.
Step-by-step explanation:
x+2=0 x=-2
x^3+3x^2+5x+6
(-2)^3+3(-2)2+5(-2)+6
-8+12-10+6
0
hence x+2 is a factor of x^3+3x^2+5x+6
x+2=0
x=-2
2x+4
2(-2)+4
-4+4
0
also x+2 is a factor of 2x+4
