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.

Y is inversely proportional to 7I+x.<br>When x = 8, y = 2.<br>Find y when x= 15.

const2013 [10]

I am taking 7I+x to mean 71+ x.

Answer: y=1.837

Step-by-step explanation:

Step 1

Let y is inversely proportional to 7I+x be mathematically be written as

y ∝ 1/7I+x

Introducing our proportionality of constant , K we have that

y ∝ 1/7I+x

y =K 1/7I+x

y= K/ 7I+xh

Step 2

so when x= 8, and y =2, k becomes

y= K/ 7I+x

k= y x (7I+x)

=2 x (71 + 8)

2x 79

=158

when x= 15, y =?

y= K/ 7I+x

y= 158/ 71 + 15

y=158/86

y=1.837
