The answer is 14/3....
hope this helps
There are 3 parts to the ratio so...
First we divide the total number of objects we are sharing (in this case 15 biscuits) by the number of parts in the ratio (3)
15 / 3 = 5
Then we know that each part of the ratio is worth 5 biscuits. So we times each part of the ratio by how many biscuits are in one part...
1 x 5 = 5
2 x 5 = 10
So when the biscuits are shared into the ratio 1:2, the number of biscuits in each are 5:10
Hope this helps :)
Answer:
72 liters of 35% acid solution and 8 liters of 85% acid solution
Step-by-step explanation:
This is a very simple mixture problem.
We let the number of liters of 35% acid solution be "x"
and
let the number of liters of 85% acid solution be "y"
Now,
we can say:
0.35x + 0.85y = 0.4(80) [we have followed "Percentage*amount" ]
Also, we know two solution amount would be 80 liters, thus we can say:
x + y = 80
or x = 80 - y
Now we substitute this into 1st equation and solve for y first. Shown below:
Thus, x = 80 - 8 = 72
So we use 72 liters of 35% acid solution and 8 liters of 85% acid solution
Y = A sin(Bx) and y = A cos(Bx). The number, A, in front of sine or cosine changes the height of the graph. The value A (in front of sin or cos) affects the amplitude (height). The amplitude (half the distance between the maximum and minimum values of the function) will be |A|, since distance is always positive.
