Answer: 209
Step-by-step explanation:
Si un número tiene 2 centenas, significa 200. Si tiene 0 decenas, entonces debería haber un 0 en el lugar de las decenas. Si un número tiene 9 unos, entonces debería haber un 9 en el lugar de las unidades. Debido a esto, el número con Número que tiene dos centenas, cero decenas y nueve unidades es 209.
English answer:
If a number has 2 hundreds, it means 200, and there should be a 2 in the hundreds place. If it has 0 tens, then there should be a 0 in the tens place. If a number has 9 ones, then there should be a 9 in the ones place. Because of this, the number with Number that has two hundreds, zero tens, and nine ones is 209.
Answer:
In order to solve this problem, you must draw a right triangle first to help you visualize the path of the jogger.
You are given 0.5 miles north (which will be the height of the right triangle), and 1.3 miles (which will be the hypotenuse of the triangle).
Using Pythagorean Theorem: a²+b²=c², we have:
0.5² + b² = 1.3²
b = 1.3²-0.5²
b = 1.2 miles

Answer:
With the initial amount and t the time on hours and t the time in hours. since the half life is 12 hours we can find the parameter of decay like this:
And solving for b we got:
And then we have:
And the model would be given by:
Step-by-step explanation:
Assuming this complete question: "A specific radioactive substance follows a continuous exponential decay model. It has a half-life of 12 hours. At the start of the experiment, 82.6g is present.
"
For this case we can create a model like this one:
With the initial amount and t the time on hours and t the time in hours. since the half life is 12 hours we can find the parameter of decay like this:
And solving for b we got:
And then we have:
And the model would be given by:
