Answer:
False
Step-by-step explanation:
No options is attached to the question. However, I'll assume it's a true or false question.
Represent the radius with r.
The circumference is calculated as:
X = 2πr
When the radius is doubled, the new radius R is
R = 2r
And the new circumference, C is:
C = 2πR
Substitute 2r for R
C = 2π * 2r
C = 4πr
Factorize the above equation.
C = 2 * 2πr
Recall X = 2πr;
The expression becomes:
C = 2 * X
C = 2X
This means that the circumference is doubled, not quadrupled.
Hence, the statement is false.
Answer:
Step-by-step explanation:
=> 3(5k + 2) + 5 = 3k - 1
=> 15k + 6 + 5 = 3k - 1
=> 15k + 11 - 3k + 1
=> 12k + 12
<u>Hence, correct answer is 12k + 12.</u>
It is 1.20 a marker. 4.80 divided by 4 equals 1.20
Answer:
If you are asking for how many points he has now that would be 25 points
Step-by-step explanation:
Because he earns 2 points for each correct we can do 13x2=26
Because he loses 0.5 points for every wrong answer we can do 0.5x2=1
So, with that information we can do 26-1=25
At the end Travis had 25 points.
