Answer:

(-8,-8)

Step-by-step explanation:

Coordinates of a midpoint:

The coordinates of the midpoint of a segment is given by the mean of the coordinates of the endpoints.

In this question:

Endpoints (-16,0) and (0,-16).

x-coordinate:

\frac{-16+0}{2} = -8

y-coordinate:

\frac{0-16}{2} = -8

Then:

(-8,-8)

.A tank contains seven liters of 10% alcohol solution. How many liters of 6% alcohol solution should be added to have 8% alcohol
zmey [24]

Answer: 7 liters of 6% alcohol solution.

Step-by-step explanation:

We have 7 liters of 10% alcohol solution, and in this the total amount of alcohol is

A = (10%/100%)*7 L = 0.1*7L = 0.7L

Now, suppose that we add N liters of 6% alcohol solution, then we have a total of:

(N + 7) Liters

And the total amount of alcohol would be:

(6%/100%)*N + 0.7L

0.06*N + 0.7L

The quotient between the total volume of alcohol and the total volume of liquid needs to be 0.08 (because we want a percentage of 8% of alcohol, and the decimal form of 8% is 0.08)

Then:

(0.06*N + 0.7L)/(N + 7L) = 0.08

We want to sove this for N

(0.06*N + 0.7L) = 0.08*(N + 7L)

0.06*N + 0.7L = 0.08*N + 0.56L

0.7L - 0.56L = 0.08*N - 0.06*N

0.14 L = 0.02*N

0.14L/0.02 = N = 7L

Then we need to add 7 liters of 6% alcohol solution.

6 is 4% of what<br> number?
Ahat [919]

Answer:

150

Step-by-step explanation:

since 4 percent would have to be multiplied by 25 to get 100 you have to multiply 6 by 25. This comes out to 150. You can even check this by doing 150 times 0.04 which is 6 so we are correct!

Help this is urgent!!!
galina1969 [7]

c = pi times d so that would mean d divided by pi would be the diameter.

to find the radius you would then have to take the diameter and times it by 1/2 bc r = 1/2 times d

i hope this helps
