Answer:

425 mm

Step-by-step explanation:

The ratio of compound A to compound B is 5 is to 6.

So, we can say that the total ratio is of 11 parts (5+6=11).

If the chemist wants a total of 935 mm of the drug, then each of the 11 parts are worth:

$\frac{935}{11}=85$

From the ratio, we know that Compound A is 5 parts. So:

$85*5=425$

425 mm of Compound A is needed.

Write an equation of the line that passes through (-3,3) and is perpendicular to the line 2y=8x-6

jok3333 [9.3K]

Answer:

y = (-1/4)x + 9/4

Step-by-step explanation:

2y = 8x - 6

So, y = 4x - 3 (Slope = 4)

Slope of perpendicular line = -1/4

Equation of line: y-3 = (-1/4)(x-(-3))

y-3 = (-1/4)x - 3/4

y = (-1/4)x + 9/4
