Dividing by a fraction is like multiplying with the inverse.
So 14 / (2/7) is the same as 14 * 7/2, which is 49
Answer:
n= 13.8 years
Step-by-step explanation:
<u>First, we need to determine the daily interest rate:</u>
Daily interest rate= 0.03 / 365
Daily interest rate= 0.000082
<u>Now, using the following formula we can determine the number of days and years:</u>
n= ln(FV/PV) / ln(1+i)
n= ln(13,000 / 8,600) / ln(1.000082)
n= 5,039 days
<u>In years:</u>
n= 5,039/365
n= 13.8 years
Answer:
2025g
Step-by-step explanation:
To solve this problem we need to take the 450g and multiply it by 4.5 (as it is 4.5 times the amount of the original recipe. 450x4+225 is the easiest way to do the math and your minced beef equals out to 2025g and your answer!
Answer: J=12
Explanation: To make this equation easier to solve, you can make everything a whole number (a.k.a. Remove the fractions). To do so, you can multiply everything in this equation by the Least Common Multiple (LCM) of all the denominators, which is 12. The equation now becomes:
-4=3J-40
Then, solve it using normal algebra:
-4=3J-40
36=3J
J=12
Much easier, right?!
Hope that helps シ
9) 35% of the 12,000 are 50-64 years old.
12,000 x 0.35 = 4,200
4,200 people were 50-64 years old
10) 25% of 596 people are over 64 years old
596 x 0.25 = 194
194 people were older than 64
11) yes, he is correct because 450 x 10%=45 and 450 x 30%=135
