Answer:
About 1.5873 ounces of sodium chloride is needed.
Step-by-step explanation:
Here, the amount of sodium chloride needed = 45 grams
Now, by the conversion of units, we know
1 gram = 0.0352739619 ounce
⇒ 45 grams = 45 x 0.0352739619 ounce = 1.5873 ounces
Hence, about 1.5873 ounces of sodium chloride is needed.
To simplify the fraction, we need to rationalize the denominator by multiplying the numerator and denominator by the conjugate.
The conjugate is the same thing as the denominator with a plus sign instead of a minus sign.
(sqrt(2) + start(5))^2/((sqrt(2) - start(5))(sqrt(2) + start(5)))
FOIL the top and bottom.
The answer is -(7+2sqrt(10))/3
The area of the rectangle is 2x(3x - 5)
I think its dilation and rotation. Hope it helps.
Step-by-step explanation:
If a variables varies jointly, we can just divide it by the other variables in relation to it.
For example, since p variables jointly as q and square of r, then
where k is a constant
First, let find k. Substitute p= 200
q= 2, and r=3.
Now, since we know our constant, let find p.
Q is 5, and r is 2.
