From that statement, we can go about making an expression.
Half of the number (x), is equal to 2 less than 2/3rds of the number<em /><em>:
0.5x = (2/3)x -2
</em>1.5x = 2x - 6
-0.5x = -6
0.5x = 6
x = 12
So a number that such that statement is true is 12.
Missing information :
The model was omitted from the question ; the possible model relating to the question was browsed online and could possibly be :
N(t) = 1.07t^2.3 for 0 ≤ t ≤ 10 months
Answer:
30.9 cases per month
Step-by-step explanation:
Given the model to determine the number of rats that have developed cancer after initial exposure ; N(t) = 1.07t^2.3
N(t) = 1.07t^2.3
Take the first derivative of N with respect to t to obtain the rate of change ;
N'(t) = (1.07)(2.3)t^2.3-1
N'(t) = (1.07)(2.3)t^1.3
The rate of growth of cancer cases at the 7th month can be calculated thus :
t = 7
N'(7) = (1.07)(2.3)t^1.3
N'(7) = 1.07 * 2.3 * 7^1.3
N'(7) = 1.07 * 2.3 * 12.549529
N'(7) = 30.884
The rate of growth of cancer at the 7th month is 30.9 cases per month.
Sorry I don’t see a pic maybe try n attach it again
So it is stated that there are 2 dirt roads with the given
measurements. Let us add the two first.
dirt road = 2 3/8 miles + 3 5/6 miles
dirt road = 19/8 miles + 23/6 miles
dirt road = (114/48 + 184/48) = 298/48 miles
The difference is:
difference = 298/48 – 4 1/3
difference = 298/48 – 13/3
difference = 298/48 – 208/48 = 90/48 = 1 42/48 = 1 7/8
Answer:
<span>1 7/8 miles</span>
