Answer:
198
Step-by-step explanation:
In order for them to be a proportion, they must be equal. 9 as a fraction is 9/1, so you need to figure out what over 22 = 9/1. so you need to multiply 1 by 22 to get 22 in the denominator, so for the numerator, you multiply 9x22, which is 198.
198/22 : 9
Answer:
Step-by-step explanation:
A new study suggests that waiting at least an hour after dinner before going to sleep reduces your risk of stroke by about two-thirds.
And for every 20 minutes more that you wait, stroke risk drops another 10%, says researcher Cristina-Maria Kastorini, MSc, a nutritionist at the University of Ioannina Medical School in Greece.
The study does not prove cause and effect -- only that there seems to be an association between waiting an hour or more between dinner and bedtime and reduced stroke risk.
Results of the 1,000-patient study were presented here at the European Society of Cardiology Congress 2011.
Answer:
25
Step-by-step explanation:
3^2w^9
Step by step solution :
Step 1 :
Equation at the end of step 1 :
0 - (9w • (0 - 3w8))
Step 2 :
Multiplying exponential expressions :
2.1 w1 multiplied by w8 = w(1 + 8) = w9
Multiplying exponents :
2.2 32 multiplied by 31 = 3(2 + 1) = 33
Equation at the end of step 2 :
0 - -33w9
Step 3 :
Final result :
33w9
