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:

b = 12

Step-by-step explanation:

Using the Pythagorean Theorem:

a² + b² = c²

You can identify that 12√12 is the hypotenuse, as it is opposite to the right angle.

So:

12² + b² = (12√2)²

144 + b² = [(12√2) (12√2)]

144 + b² = (12 × √2 × 12 × √2)

144 + b² = (144 × 2)

144 + b² = 288

b² = 144

√b² = √144

b = 12

Step-by-step explanation:

The probability that a random customer will not rent a drama is 4/5. Option B is correct.

Probability can be defined as the ratio of favorable outcomes to the total number of events.

here,
Total number of rented DVDs = 25 + 36 + 52 + 12 = 125
Number of Drama movies = 25

The probability that a random customer will rent a drama.
P(D) = 25 / 125 = 1/5

Now,
The probability that a random customer will not rent a drama,
P(D)' = 1 - P(D)
       = 1 - 1/5 = 4/5

Thus, the probability that a random customer will not rent a drama is 4/5. Option B is correct.

Answer:

An expression for the length is:

Step-by-step explanation:

Given

Area of a rectangular dog pen = A = 64xy square units

Width = w = 4y

To determine

The length = l = ?

We know that the area of a rectangular object is

A = l × w

where w is the width and l is the length of the rectangle.

substituting w = 4y and A = 64xy in the equation

[tex]A=l\times w[/tex]

[tex]64xy\:=l\times 4y\:[/tex]

[tex]\:\:l=\frac{64xy\:}{4y\:\:}[/tex]

Divide the numbers: 64/4 = 16

[tex]l=\frac{16xy}{y}[/tex]

Cancel the common factor: y

[tex]l=16x[/tex]

Therefore, an expression for the length is:

Answer:

Step-by-step explanation:

Find the slope = -2/1

Find the y-intercept = 5

Go to graph

put a dot at (0,5)

since it's a negative slope you will go up 2 and left 1

draw your line

_________________________________________________

Find the slope = 3/1

Find the y-intercept = 0

go to graph

Put a dot at (0,0)

Since it is a positive slope you will go down 3 and left 1.

To find the slope and y-intercept use this formula=

y=mx+b

m=slope

b=y-intercept

I'm sorry I don't know how to do a check equation for these.

Answer:

Step-by-step explanation:

Remark

It's not 82.

You have to take the 62% off and then follow it with 20% from the new price.

Solution

62%

If you get a reduction of 62%, it means that you pay 100% - 62% = 38% of the marked price of $49.95.

38% price =49.95 * 62/100

38% price = 3096.9 / 100

38% price = $30.97

20%  Reduction

20% more means that you pay 100% - 20% = 80%

20% more reduction = 30.97 * 80/100

20% more reduction = 2478/100

20% more reduction = 24.78

Conclusion.

Your final price before taxes is $24.78

Answer:

70%

Step-by-step explanation:

Answer:

16%

Step-by-step explanation:

To calculate this we first need to calculate the probability of Mario scoring for every individual shot that he takes. Since he makes 2 goals for every 5 shots on average, we simply divide these numbers to get the probability of a goal per shot.

2 / 5 = 0.4  ...multiply by 100 to get percentage value

0.40 * 100 = 40%

We see that the probability of scoring a goal per shot is 40%. Now we need to multiply this probability twice to get the probability of scoring 2 consecutive goals in two shots.

0.40 * 0.40 = 0.16  ... multiply by 100 to get percentage value

0.16 * 100 = 16%

Answer:

16%

Step-by-step explanation:

I know that 2/5 = 0.4 or 40%

and 0.4 x 0.4 = 0.16

or 16%
