a patient was supposed to take 560 mg of medicine but took on The 420 mg what percent of medicine does she take

Sav [38]

You need to set the correct porportion. x is the percent value you want to find. 100 is the maximum percentage. 420mg is what was taken out of the maximum 560mg dose.

$\frac{x}{100} \times \frac{420}{560}$

You will cross multiple.

$560x = 42000$

you will divide 42000 by 560

$\frac{560x}{560} = \frac{42000}{560}$
$x = 75$

The complete answer will be: The patient took 75% of the 560mg dose of medication.

Answer:

x = 8√2

Step-by-step explanation:

As the opposing side of the angle and the hypotenuse are given, take the sine ratio of the angle.

sin 45° = x/16
1/√2 = x/16
x = 16 / √2
x = 16√2 / 2
x = 8√2

What are the possible values of x if (4c-5)^2= 49?

kykrilka [37]

Answer:

c = 3 c = -1/2

Step-by-step explanation:

(4c-5)^2= 49

Take the square root of each side

sqrt((4c-5)^2)= ±qrt(49)

4c-5 = ±7

Separate into two equations

4c-5 = 7 4c-5 = -7

Add 5 to each side

4c-5+5 = 7+5 4c-5+5 =-7+5

4c =12 4c = -2

Divide by 4

4c/4 = 12/4 4c/4 = -2/4

c = 3 c = -1/2

Answer: You would have to send 300 text messages

Step-by-step explanation:

1. Turn problem into 20 + 0.10x = 50

2. Subtract 20 from both sides to get 0.10x = 30

3. Divide both sides by 0.10 to get x = 300
