In a book about birds, there is a drawing of a sea eagle that shows a wingspan of 2.8 cm. If the book says the scale is 1:90, what is the actual wingspan of the sea eagle.
Answer:
2.52
Answer:
use a calculator
Step-by-step explanation:
also if this is easier change 1/2 and 1/3 to 0.5 and 0.3 where it would be 8.5 x 3.3
Answer:
(x-5)^2+2
Step-by-step explanation:
To convert between standard and vertex form, you have to complete the square (which, as a reminder, (a+b)^2 = a^2+2ab+b^2).
Since a^2 is x^2, and 2ab is -10x, then b must be -5, so b^2 is 25. Therefore, we add and subtract 25 from the expression:
(x-10x+25)+27-25
Then, we can make (x-10x+25) to (x-5)^2:
(x-5)^2+2
Answer:
A
Step-by-step explanation:
Since x is along the entire parallelogram we will use cosine to figure out it's length.
First we do cos(40) and get cos(40)=.7660
This .7660 is equal to 
or 
So we do .7660*4 and get 3.064 in for x
A is the only option with x=3.06 so it is the correct answer
5x8= 10x4
40=40
40 is equal to 40
