Answer:
12,345 tablets may be prepared from 1 kg of aspirin.
Step-by-step explanation:
The problem states that low-strength children’s/adult chewable aspirin tablets contains 81 mg of aspirin per tablet. And asks how many tablets may be prepared from 1 kg of aspirin.
Since the problem measures the weight of a tablet in kg, the first step is the conversion of 81mg to kg.
Each kg has 1,000,000mg. So
1kg - 1,000,000mg
xkg - 81mg.
1,000,000x = 81
![x = \frac{81}{1,000,000}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B81%7D%7B1%2C000%2C000%7D)
x = 0.000081kg
Each tablet generally contains 0.000081kg of aspirin. How many such tablets may be prepared from 1 kg of aspirin?
1 tablet - 0.000081kg
x tablets - 1kg
0.000081x = 1
![x = \frac{1}{0.000081}](https://tex.z-dn.net/?f=x%20%3D%20%5Cfrac%7B1%7D%7B0.000081%7D)
x = 12,345 tablets
12,345 tablets may be prepared from 1 kg of aspirin.
Answer:
89
Step-by-step explanation:
On the first test, she got 3 more points than the average required, so she can afford to drop 3 points below the average on her second test. She needs 92-3 = 89 or better.
Answer:
37.7359
Step-by-step explanation:
first you visualize the shape created
if you visualize it... it will look like a right angled triangle
and we are looking for the longest side
remember the pythagoras theorem c^2= a^2 + b^2
in this case we are looking for c
a^2= 20^2
b^2= 32^2
400+ 1024= 1424
therefore c^2= 1424
then you square root 1424
to get 37.7359

Answer:
71
Step-by-step explanation:
the fractional part is 5 and 5 is 5 or above. Therefore, we add 1 to the integer part and remove the fractional part to get the answer Therefore, we add 1 to the integer part and remove the fractional part to get 70.5 rounded to the nearest whole number which is 71
