Answer:

Step-by-step explanation:

Set this up as a proportion with the ratios being

\frac{vinegar}{oil}  If there is a 2:5 ratio of vinegar to oil, that ratio looks like this:

\frac{v}{o}:\frac{2}{5} and if we are looking for how much oil, x, is needed for 20 ml of vinegar, then that ratio completes the proportion:

\frac{v}{o}:\frac{2}{5}=\frac{20}{x} and cross multiply.

2x = 100 so

x = 50 ml of oil

Write square root of 64 - square root of -289 as a complex number in the form of a+bi
stellarik [79]

Answer:

\sqrt{64}-\sqrt{-289}

=8-17i

Step-by-step explanation:

\sqrt{64}=8 because 8(8)=64 and 8 is the positive square root of 64.

\sqrt{-289}=17i because 17i(17i)=289i^2=-289(-1)=-289.

\sqrt{64}-\sqrt{-289}

8-17i

What is the answer plz help.
Dima020 [189]

Answer:

0.2

Step-by-step explanation:

C.O.P-the constant value of the ratio of two proportional quantities x and y, typically the equation is Y=KX.

So to find that you would divide y by x.

In this case the dot is between 0 and 2 on y so it is 1 and between 4 and 6 on x so it is 5.

Then you would divide 1/5 and get 0.2 or you could look at the end of the graph and notice that the last point is at (10,2) and divide 2/10 and get the same thing.

HOPE THIS HELPS!!!
