ANSWER
EXPLANATION
The given expression is
We remove the perfect squares under the radical sign.
We can now take square root of the perfect squares and simplify them further.
This simplifies to:
This further simplifies to:
Answer:
1, 5 and 6.
Step-by-step explanation:
The sides of this triangles has lengths in the ratio x : √3x : 2x where 2x is the hypotenuse.
When C = 30, the side AB is the small leg (=x).
When B = 90, the hypotenuse is AC ( =2x).
When A = 60, the larger leg is BC (=√3x).
1. AB = 4, BC = 4√3 :- Are possible legs.
5 AB = 7, AC = 14. :- AB = small leg, AC = hypotenuse.
6. AB = 11, BC = 11√3:- AB = small, BC = larger leg.
The answer is 3.6 or 3 6/10 or 3 3/5 all equivalent
1 cartons of juice = $4.20
3 single cartons = 4.20 * 3 = $12.60
1 pack = $9.45
He saved 12.60 - 9.45 = $3.15
So, he saved $3.15, compared to the total ($12.60)
To calculate the percentage, we will do a proportion:
3.15 (money saved) : 12.60 (total of 3 single cartons) = x (how much percentage) : 100 (total)
3.15 : 12.6 = x : 100
To calculate x, we will moltiplicate the ends (where we have known numbers) than divide all per 12.6
So
x = (3.15 * 100) / 12.60 = 315 / 12.6 = 25
So the percentage saving is 25%
A
4+8=12 wrong
4.5+8=12.5 wrong
5+8=13 wrong
5.5+8=13.5 right
the rest of the numbers are above 5.5 so they aren't wrong
<u>5.5, 6 and 6.5 makes the inequality true
</u>
B
x+8>13
x>13-8
<u>x>5
</u>
C
<u>x=5 is not a solution to the inequality because 5+8 is not more than 13.</u>
