Given:
15 mL of a solution contains 75 mg of medication.
To find:
How many mg of medication are in 60 mL of solution?
Solution:
We have,
Medication in 15 mL of a solution = 75 mg
Medication in 1 mL of a solution = [tex]\dfrac{75}{15}[/tex] mg
= [tex]5[/tex] mg
Medication in 60 mL of a solution = [tex]60\times 5[/tex] mg
= [tex]300[/tex] mg
Therefore, 60 mL of a solution contains 300 mg of medication.

Answer:
She shouldn't tip at all since that's a ridiculous concept
Step-by-step explanation:
common sense
SORRY MADE A MISTAKE WITH THE CALCULATOR I KNEW I MESSED SOMETHING UP
The cost of the meal was $22 so that's the price plus tax and tax is 10% of the price so
cost = price + 0.1*price
cost = 1.1 * price
price = cost / 1.1
price = 22 / 1.1 = 20
now we need 20% of that so that's
20 * 0.2 = 4
If she's simple-minded enough to tip that would amount to $4

The equation that passes through (3,6) and is perpendicular to 3x - 4y = - 2
a
y = - 4/3x + 3 1/3
b
y = - 3/4x + 10
c
y = - 4/3x + 10
d
y = 3/4x + 10
Answer:
C
Step-by-step explanation:
We want the equation of the line that passes through (3, 6) and is perpendicular to:
[tex]3x-4y=-2[/tex]
First, convert the second equation into slope-intercept form:
[tex]-4y=-3x-2\Rightarrow \displaystyle y=\frac{3}{4}x+\frac{1}{2}[/tex]
So, we can see that the slope of the line is 3/4.
The slopes of perpendicular lines are negative reciprocals of each other.
Therefore, the slope of the new line is -4/3.
It passes through the point (3, 6).
We can use the point-slope form:
[tex]y-y_1=m(x-x_1)[/tex]
Substitute:
[tex]\displaystyle y-(6)=-\frac{4}{3}(x-3)[/tex]
Distribute:
[tex]\displaystyle y-6=-\frac{4}{3}x+4[/tex]
Therefore:
[tex]\displaystyle y=-\frac{4}{3}x+10[/tex]
The answer is C.

17n + 4n- 4= 122
how do i solve for n?
Answer:
n = 6
Step-by-step explanation:
17n + 4n - 4 =122
combine like terms 17n & 4n
21n - 4 = 122
21n - 4 + 4 = 122 + 4
21n = 126
21n / 21 = 126 / 21
n = 6

awnser im believe it is 24 i think
Answer:
20 units square
Step-by-step explanation:
do the Pythagoras theorem
a²=b²+c² ⇒ a=√b²+c²
if b is 4 and c is 2 an a is the unknown
so a=√(4)²+(2)²
a=√20
then get the rule of the area of the square
Area of the square= s²
s=a=√20 (a is the hypotenuse of the triangle and also a side in the square)
so s²=20
Area of the square=20 units square

Answer:
There would be a y-intercept of one and a slope of -3/4.
Step-by-step explanation:
Negative slope means it will increase going left.
3/4 is the slope 3 rise/ 4 run
the y intercept is 1, so the line will cross the y axis at the 1 point.
