The Baker formula estimates the maximum heart rate, in beats per minute, of a person who is

seropon [69]

Answer:

For a=16, the Maximum Heart Rate is 188 Beats Per Minute.

Step-by-step explanation:

To begin, we know that the formula:

$b(a)=200-0.75a$ Eqn(1).

is equivalent to a linear equation of algebraic form denoted as:

$y=k+mx$ Eqn(2)

as such that Eqns (1) and (2) relate as follow:

$y$ ⇔ $b(a)$ : denoting our Dependent Variable, in this case Max. Heart Rate in Beats Per Minute

$x$ ⇔ $a$ : is our Independent Variable, in this case the Age of the Person

$m$ ⇔ $0.75$ : denoting the Rate of Change of the Age.

$k$ ⇔ $200$ : denoting our Constant.

Now in the question our value of $b(a)$ is given as 188 beats per minute, which by plugging in Eqn(1) gives:

$200-0.75a=188$

from which we can solve to obtain the value of $a$ as follow:

$-0.75a=188-200$ Gather similar terms on each side

$-0.75a=-12\\$ Simplify

$a=\frac{-12}{-0.75}$ Solve for $a$

$a=16$

Which tells us that at the Age of 16, the Max. Heart Rate is 188 Beats Per Minute.

Phantasy [73]

Keywords:

Medium sodas, buy, dollars, divide

For this case we must find the amount of medium sodas that Natalie's group can buy, taking into account that they have 20 dollars and that each medium soda costs 1.25 dollars. To solve, we must divide:

Let "x" be the number of medium sodas you can buy, then:

$x = \frac {20} {1.25}\\x = 16$

So, Natalie's group can buy 16 medium sodas with 20 dollars

Answer:

16 medium sodas
