Answer:
2) If the scale factor is 2, draw a line from the centre of enlargement, through each vertex, which is twice as long as the length you measured. If the scale factor is 3, draw lines which are three times as long. If the scale factor is 1/2, draw lines which are 1/2 as long, etc. The centre of enlargement is marked.
Step-by-step explanation:
Answer:50 degress 2/2
Step-by-step explanation:
2/2
Using difference of squares
=(a-b)(a+b)
with a = x and b = 3
i
+ 18 =(x-3 i)(x+3 i)
Answer:
10
Step-by-step explanation:
multiply 15 by the numerator (2) so you should have 30/3 then divide by the denominator (3) for an answer of 10
Answer:
Let's name each of the three sections of the rocket as:
-
payload and navigation
-
fuel
-
engine
Now, we are told that:
The top section is one-sixth the length of the bottom section:
(1)
The middle section is one-half the length of the bottom section:
(2)
The total length is 240ft:
(3)
We may begin by substiting (1) and (2) in equation (3), in order to find the value of the engine section :
(4)>>>> Value of the engine section length
Then, we substitute this value of in equations (1) and (2):
(5)>>>> Value of the payload and navigation section length
(6)>>>> Value of the fuel section length
