Answer:
Scale factor = 3
Step-by-step explanation:
Scale factor used for the dilation = the ratio of the corresponding side length of the new figure to the side length of the original figure
Scale factor = B'C'/BC
B'C' = 9 units
BC = 3 units
Scale factor = 9/3 = 3
6(1/2 + 2/3 + 3/4)
= 6(1/2) + 6(2/3) + 6(3/4)
= 3 + 4 + 4 1/2
= 11 1/2
Answer
11 1/2 (23/2 or 11.5)
Answer:
For any circle of radius r
The diameter of the circle = two times of the radius = 2r
And The Circumference= C = 2πr
14. If r = 8
So, d = 2r = 2 * 8 = 16 cm
C = 2πr = 2 * π * 8 = 50.27 cm (to the nearest hundredth.)
15. If d = 9 m
So, d = 2r
∴ r = d/2 = 9/2 = 4.5 m
And C = 2πr = 2 * π * 4.5 = 28.27 m (to the nearest hundredth.)
Answer:
H.''n is not divisible by 6 and n is not divisible by both 2 and 3.
Step-by-step explanation:
We are given that a statement ''n is divisible by 6 or n is divisible by both 2 and 3.''
We have to write the negation of the given statement.
Negation: If a statement p is true then its negations is p is false.
n is divisible by 6 then negation is n is not divisible by 6.
n is divided by both 2 and 3 then negation is n is not divisible by both 2 and 3.
Therefore, negation of given statement
''n is not divisible by 6 and n is not divisible by both 2 and 3.
Hence, option H is true.
