Answer:
17.5
Step-by-step explanation:
The ratio of "pure drug" to liquid is 35:150
Therefore to evaluate for 75 mls we get the ratio 75/2150 or simply 1/2
we can then multiply 35 by the ratio 1/2
35/2=17.5
State the answer
In 75 mls there are 17.5 grams of pure drug
Answer:
Slope = 2/3
Step-by-step explanation:
Slope = Change over y (rise) over change over x (run)
Pick two dot points on the line
Count how many units over they are until you get to the next dot, then count how many units up until you reach the next dot
Remember: Y runs vertically, X runs horizontally
Put the unit number that ran vertically on the top, then put the unit number that runs horizontally on the bottom
If needed simplify
The slope is 2/3
Answer:
A. ∠AOD = 170°
Step-by-step explanation:
103° + 55° + 12° = 170°
Answer:
y = (-1/2)x + 21/2
Step-by-step explanation:
Given equation:
y - 2x + 7
Coordinates = (5,8)
Find:
Perpendicular equation
Computation:
y = mx + c
y - 2x + 7
y = 2x - 7
So,
m = 2
The negative reciprocal of 2 is -1/2
So,
For,
Coordinates = (5,8)
y = mx + c
8 = (-1/2)(5) + c
8 = -5/2 + c
c = 8 + 5/2
c = 21 /2
So,
y = mx + c
y = (-1/2)x + 21/2
