A science teacher has a supply of 50% sugar solution and a supply of 80% sugar solution. How much of each solution should the te
mash [69]
How much of each solution should the teacher mix together to get 105 ML of 60% sugar solution for an experiment?

1. Look at how 60% is closer to the solution of lower concentration (50%). You can deduce that you will be mixing a higher volume of the 50% solution.

2. All 4 answers add up to 105ml.

3. The intuitive answer is the first option:
70 ML of the 50% solution and 35 ML of the 80% solution

4. Let's check whether point 3 is true.
70ml/105ml X 0.5 + 35ml/105ml X 0.8 = (35 + 28)/105= 63/105= 60% / 105 ml = 105ml of 60% sugar solution

Two points, A and B, are on opposite sides of a building. A surveyor chooses a third point, C, 60 yd from B and 105 yd from A, w
Virty [35]

In the given question it is given that , AC = 105 yd, BC = 60 yd and angle ACB= 69.3 degree.

We have to find the distance of AB, and for that we use law of cosine, which is

(AB)^2 = (AC)^2 +(BC)^2-2(AC)(BC) cos \theta

Substituting the values of AC, BC and theta, we will get

(AB)^2 = 105^2 +60^2 -2(105)(60) cos 69.3

(AB)^2 = 10171.217

AB= 101 yard

Solve the simultaneous equations. <br> Please help
gavmur [86]

Answer:

x=1/2, y=4

Step-by-step explanation:

Double both sides of the top equation:

4x+6y=26

Now subtract boths sides of the second one from the first one:

(4x+6y) - (4x-y) = 26 - (-2)

7y = 28

so y = 4

4x-y=-2 so 4x-4=-2

4x=2

x=1/2
