Answer:
What?...
Step-by-step explanation:
Answer: e. 2h + 3 = 10; h = 3.5h
Explanation:
Jane can run 2 miles per hour. (2h)
He need to run 10 miles in total and has done 3 so far. (+ 3 = 10)
The equation can be written:
2h + 3 = 10
2h = 7
h = 7/2 = 3.5
The answer is 1728
First you must set up the equation
Then, you must multiply the numerator
Next, divide
Finally, simplify exponents
12*12*12=1728
Since both shapes are the same,we divide the total perimeter by 2. 80<span>÷2 is 40. Now that we have the perimeter of each individual shape we have to figure out the length of one side. Since all the sides are equal in length there is only 1 shape that has that - a square. A square has 4 sides so we need to divide 40 by 4 (because squares have 4 sides) and that equals to (40</span><span>÷4) 10cm on each side. Hope I helped!</span>
Answer:
It is false that, if the national economy shrank at an annual rate of 9% per year for three consecutive years then the economy shrank by 27% over the 3-year period, because this percentage does not follow a linear path, but on the contrary, it is calculated exponentially: 9% of each year is calculated on the rest that remained after discounting 9% the previous year.
Thus, if the national economy has a value of 100, after three years it will not have a value of 79, but a value of 75.35, as it arises from the following calculation:
100 x 0.91 ^ 3 = X
100 x 0.753571 = X
75.35 = X
