Pure acid is to be added to a 10% acid solution to obtain 117 L of a 20% acid solution. What amounts of each should be used?
creativ13 [48]

Answer:

A typical mixture equation

:

x + .10(54-x) = .20(54)

x + 5.4 - .10x = 10.8

x - .1x = 10.8 - 5.4

.9x = 5.4

x = 5.4%2F.9

x = 6 L of pure acid to be combined with: 54-6 = 48 L of 10% solution

Consider angle θ in Quadrant II, where sinθ = 4/5 . What is the value of cosθ?
Kay [80]

Answer:

3/5

Step-by-step explanation:

sin theta=opposite/hypotenuse

4/5=opposite/hypotenuse

therefore opposite=4 and hypotenuse=5

for adjacent

using pythagoras theorem

a^2+b^2=c^2

opposite^2 + adjacent^2 =hypotenuse^2

4^2 + adjacent^2 =5^2

16 + adjacent^2 =25

adjacent^2 =25-16

adjacent =\sqrt{9

adjacent=3

cos theta=adjacent/hypotenuse

=3/5

therefore the value of cos theta is 3/5

convert the mixed numbers to improper fractions. this will get you one step closer to finding the unit rate
Kaylis [27]
It means for example instead of writing 2 2/5 You would write 12/5
You can find out an improper fraction by simply multiplying the denominator by the front number and adding the answer to you numerator
So, 2x5= 10. 10+2= 12. So 12/5
