To
get the milliliters of alcohol used, we must multiply 690 by 0.03. If we do
this, we will get 20.70, which means that 20.70 milliliters of alcohol were
used. On the other hand, we can get the milliliters of water used through two
ways: the first one is by simply subtracting 20.70 from 690, which will give us
the answer 669.30. Another would be by multiplying 690 by 0.97, which will also
yield the answer 669.30. The number of milliliters of water used was 669.30.
Answer:
Step-by-step explanation:
it doesn't really say what the "face" is, but i'll guess that it's the part marked in yellow? if that's the case then it's just 10 * 10 twice for each of the squares. Really you couldn't see that? :/ 200 is the answer
Answer:
a) linear
b) nonlinear
c) nonlinear
d) nonlinear
Step-by-step explanation:
For a linear equation the highest degree is 1. If the degree is more than 1, then it is a non-linear equation.
a) 7x=y-4 is a linear equation because the highest degree is one
b)
is not a linear equation because when we multiply through by x, we get
The degree is 2
c) 6xy +3x=2 is non linear because the degree is 2.
d) x=2y³ +y is non-linear be because the degree is 3.
So if there are 60 clownfish and the ratio from clownfish to angelfish is 5:4, this is the equation you are looking at:
5:4 = 60:?
To find ? you have to do 60 divided by 5 which equals 12 and multiply it times 4 to see how many angelfish there will be if there are 60 clownfish.
12 x 4 = 48
So if there are 60 clownfish there will be 48 angelfish. The ratio is 60:48
For the next one, same thing if there are 48 angelfish, then you are looking at this equation:
4:3 = 48:?
Again, we solve like we did the last one.
48 divided by 4= 12
3 x 12= 36
So, if there are 48 angelfish there will be 36 goldfish. The ratio is 48:36
I hope this helps:)
