Answer:
5sqrt3
Step-by-step explanation:
Using the pythagorean theorem, we have a^2+4^2=9^2
a^2 + 16 = 81
a^2 = 75.
a = sqrt75.
75 = 25*3. 25 is a perfect square, so sqrt75 = 5sqrt3
Answer:

Answer:
The expressions are not equivalent.
Step-by-step explanation:
Three-tenths of the total volume, v =
= 0.3 × v --- (1)
But, 310x is 310 × v --- (2)
Since (1) and (2) represent the same volume,
0.3 × v = 310 × v
Divide both sides by v,
0.3 = 310 which is a contradiction.
Therefore, the expressions are not equivalent.
Answer:
8
Step-by-step explanation:
sqrt((x-1)/2)^2))=3.5
square root and squared cancel out
(x-1)/2 = 3.5
x-1 = 7
x = 8
Answer:
60%
Step-by-step explanation:
You divide the amount spent on fruit ($35) by the total ($60) ((35/60= ?)) to get 0.6 which also makes it 60.
hope this helps
