A pharmacist needs to combine a mixture for a patient. She uses 5 mg of antibiotic for 25 mg of the mixture. If the patient needs 100 mg of the mixture, how much antibiotic should the pharmacist use?
20 mg
30 mg
80 mg
120 mg
500 mg

20 mg

Step-by-step explanation:

5/25 mg

multiply 25 by 4 to get 100 so also multiply 5 by 4 to get 20 mg of the antibiotic.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

6.5
