<span>Figure out what is the commonality for each ratio.
There are India stamps in each ratio, so India is the commonality.
Now you simply take the two ratios and multiply them until India has the same amount.
So, Multiply the first by 5 to get a ratio of 25 US to 10 Indian
Multiply the second by 2 to get a ratio of 10 Indian to 2 British
Now that you have "10 Indian" in both ratios, they match up
You have 25 US : 10 Indian : 2 British.
Since the answer is only asking for US and British, you only need 25 US : 2 British</span>
Answer:
Step-by-step explanation:
If we let x = the amount of 5% solution and y = the amount of pure alcohol, we can set up that
.05x+y is the amount of alcohol in our resulting mixture, and x+y is the total amount in our resulting mixture (which we know is 380)
so we also know that:
(.05x+y)/380 = .6
If we simplify this we come up with:
.05x+y=228
and we know x+y=380
If we solve this as a system of equations, we will find that:
x=160 ml
y=220 ml
P(-3)= -2(-3) -2
p(-3)= 6-2
p(-3)= 4
The sum of 2a and 3b:
2a + 3b
What you need to know for this case is that the sum of the internal angles of a triangle is 180 °
We then have the following equation that is given by:
(2x) + (3x) + (4x) = 180
Clearing x we have:
9x = 180
x = 180/9
x = 20
Therefore we have:
m∠A = (40) °
m∠B = (60) °
m∠C = (80) °
Answer:
B) m∠B = 60 °
