Last question is in the attachment.

Let X = ml's of 3% hydrochloric acid and Y = ml's of 10% hydrochloric acid

Add X and Y to get the total milliliters:

X + Y = 175

Now multiply the quantities by their percentages go get the 6% required:

0.03x + 0.10y = 0.06(175)

Rewrite the first equation as x = 175 -y

Now replace x in the second equation and solve:

0.03(175-y) + 0.10y = 0.06(175)

Simplify:

5.25 - 0.03y + 0.10y = 10.5

Combine like terms:

5.25 +0.07y = 10.5

Subtract 5.25 from both sides:

0.07y = 5.25

Divide both sides by 0.07:

y = 5.25 / 0.07

y = 75

Now you have y solve for x:

x = 175-y = 175 - 75 = 100

You need  100 ml's of the 3% solution and 75 ml's of the 10% solution.

answer: 88

step-by-step explanation:

a, b, c, d are correct.

step-by-step explanation:

we have g(x) = 3 and are required to find which option is a translation of g(x).

now, 'translation' is a transformation which means to shift the function in any direction and the general form of translation is g(x) + k, where k is any real number.

so, according to the options we see that all are correct as they satisfy the general form of translation.

also, it can be seen from the graph below that the function g(x) = 3 is shifted from its position in all the four options.
