<span> SO in total, Emily and Sarah had a total of 80
dollars in which Emily had twice as much as Sarah.
Let’s solve to find out how much their Money is.
=> Since the ratio of the given data is 2:1, 2 + 1 =3, so let’s divide 80 by
3
=> 80 / 3 = 26.667 ,
=> Emily has twice as this.
=> 26.667 * 2 = 53.33
=> Sarah has 26.67
Now, Sarah spent 1/3 of her money
=> 26.67 / 3 = 8.89 – her remaining money
Emily spent 17 dollars of her money
=> 53.33 – 17 = 36.33</span>

Step-by-step explanation:
Remark
The editor must have brackets put around the denominator when there are 2 terms.
That means I think the question is (√5) / (√8 - √3). If this is incorrect, leave a note.
To rationalize the denominator, you must multiply numerator and denominator by the conjugate (√8 + √3).
Solution
√5 * (√8 - √3) / ( (√8 - √3) * (√8 + √3) )
I don't think there is any point in removing the brackets in the numerator. Just leave it.
The denominator is a different matter.
denominator = ( (√8 - √3) * (√8 + √3) )
√8 * √8 = 8
√8 * √3 = √24
- √3 * √8 = - √24
-√3 * √3 = - 3
Take a close look at the 2 middle terms. They cancel out because one of them is plus and the other minus.
What you are left with is 8 - 3 = 5
So the final answer is
√5 * (√8 - √3)

Answer:
<u>TO FIND :-</u>
- Length of all missing sides.
<u>FORMULAES TO KNOW BEFORE SOLVING :-</u>
<u>SOLUTION :-</u>
1) θ = 16°
Length of side opposite to θ = 7
Hypotenuse = x


≈ 25.3
2) θ = 29°
Length of side opposite to θ = 6
Hypotenuse = x


≈ 12.3
3) θ = 30°
Length of side opposite to θ = x
Hypotenuse = 11


4) θ = 43°
Length of side adjacent to θ = x
Hypotenuse = 12


≈ 8.8
5) θ = 55°
Length of side adjacent to θ = x
Hypotenuse = 6


≈ 3.4
6) θ = 73°
Length of side adjacent to θ = 8
Hypotenuse = x


≈ 27.3
7) θ = 69°
Length of side opposite to θ = 12
Length of side adjacent to θ = x


≈ 4.6
8) θ = 20°
Length of side opposite to θ = 11
Length of side adjacent to θ = x


≈ 30.2
The rate of separation = 25 + 15 = 40 mph
speed = distance / time
40 = 30 / t
t = 30/40 hour = 45 minutes
Its C.
