Answer: 40%
Step-by-step explanation:
The consumption of a vegetable has decreased. While the consumption per capita in 2000 was 25.2 pounds, in 2010, the consumption dropped to 15.2 pounds.
Consumption in 2000= 25.2 pounds
Consumption in 2010= 15.2 pounds
Difference in consumption=
25.2 - 15.2 = 10.0
Percentage decrease will be difference in consumption divided by original consumption in 2000 multiplied by 100. This will be:
= 10.0/25.2 × 100
= 0.4 × 100
= 40%
To solve this problem, we first must rewrite each term in the form k times a^n so that we can compute the multiplication afterwards. To do this, we must remember that the square root of a is equivalent to a^(1/2) and that variables in the denominator have negative exponents. Using this knowledge, we can rewrite the given expression as:
a^(1/2) * (2a² - 4a^(-1))
Now, we must recall that when terms with the same base are multiplied together, we must add the exponents when simplifying. This step is shown below.
2a^(1/2 + 2) - 4a^(1/2 - 1)
The next step is to perform the addition of the exponents and obtain our final answer.
2a^(5/2) - 4a^(-1/2)
The above expression is your final answer.
Hope this helps!
In this item, we are basically to get the value of the least number that can be divided both by 6 and 7. In other words, we are to get the least common multiple or (LCM). This is obtained by multiplying the 2 numbers. Thus, after 42 days, they will go golfing the same day again.
