To add fractions you want to make sure that the bottom numbers are the same so we have to make them the same, but we have to make sure that the fractions are unchanged so we get the correct answer
so if we find out what number that 9,7, and 5 can all multiply into. we find that 9 times 7 times 5 or 315 is the number that will work
so to get them to all be over 315, we must multiply each fraction by a form of 1/1 or x/x or (number)/(same numbe as on top)
so 7/9 times (35/35)=245/315
1/7 times (45/45)=45/315
3/5 times (56/56)=168/315
we add them togther
245/315+45/315+168/315=(245+45+168)/315=458/315
this simplifies to 1 and 143/315
Answer:
The first day of spring is Thursday, March 19th.
The first day of summer is June 20th. So, Spring ends on June 20th.
Step-by-step explanation:
<em>I looked it up on the internet instead of asking on brainly.</em>
Area = width * height
since the window is 20 inches higher than the width:
width +20 = height
640 = width * width+20
640 = width^2 +20*width
width^2 +20*width - 640 = 0
width = 17.203
**********************************************************
Double Check
if width = 17.203 then height = 37.203
area = 17.203 * 37.203 = 640 square inches Correct!!
Answer:
1 tablet
Step-by-step explanation:
Data provided in the question:
The dose of the Uniphyl = 5 mg/kg
Strength of the Uniphyl = 400 mg per tablet
Weight of the patient = 76 kg
Now,
The recommended dose for the patient
= Dose of the Uniphyl × weight of the patient
= 5 mg/kg × 76 kg
= 380 mg
Therefore,
The number of tablets to be administered to the patient
= 
= 
= 0.95 ≈ 1 tablet
Hence,
The number of tablets to be administered to the patient is 1
The answer should be 42 times.
