Answer:
Segment BF = 15
Step-by-step explanation:
Segment DE is parallel to segment BC
Segment EF is parallel to segment AB.
Because segment EF is parallel to segment AB, triangles ADE and EFC are proportional. We must find the scale factor which these two triangles are proportional.
24 ÷ 20 = 1.2
Scale Factor = 1.2
18 ÷ 1.2 = 15
Segment EF is parallel to segment AB so segment EF is congruent to segment DB.
hope this helps! ps. im very sorry about the previous wrong question, but i hope this is right (,,>﹏<,,) xx
Answer:
it is A. 2.5 g/cm3
Step-by-step explanation:
d=m/v
d=32.25/12.9
d=2.5g/cm3
Given:
The sequence is
436, 218, 109, 54.5, 27.25,...
To find:
The explicit formula for the given sequence.
Solution:
We have,
436, 218, 109, 54.5, 27.25,...
It is a GP because the two consecutive terms have common ratio.
Here,
First term : a=436
Common ratio : d = 
= 
= 
Now, the explicit formula for a GP is

Where, a is the first term and r is the common ratio.
Putting a=436 and r=0.5, we get

Therefore, the correct option is c.
X/6 + 4 = 15
First, subtract 4 to both sides:
x/6 = 11
Now multiply 6 to both sides:
x = 66
Answer:
the weight for an object with a velocity of 12 meters per second is 600 kilograms
Step-by-step explanation:
The linear momentum of an article is : p = mv
Where p = Momentum
m = mass
v = velocity
The velocity is 16 meters per second and the object weighs 450 kilograms
So, 
We are supposed to find the weight for an object with a velocity of 12 meters per second
So, p = 12m
We are given that the linear momentum is a constant when the mass varies inversely of the velocity.
So, 
Hence the weight for an object with a velocity of 12 meters per second is 600 kilograms
