48.85177 then round it to whatever is necessary :)
5 (5/8) * 1 (5/9) = 45/8 * 14/9 = 630/72 = 8 (54/72) = 8 (3/4) miles
The answer is: [C]: " 2⁴ " .

The ratio of outputs is: 4:(1/4) = 4:(1/4) = 4 ÷ (1/4) = 4/1 * 4/1 = 16/1 = 16:1 = 16.
From the answer choices given, "2⁴ = 16" ; since: " 2*2*2*2 = 16 ";
which corresponds to:

Answer:
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.
Step-by-step explanation: :)
Answer:
2,600
Explanation:
Your first step is to find 7% of 4000 ( this is what it is decreasing by per year).
As a result you end up with 280.
Multiply 280 by 5.
1,400 should be your answer( amount of km decreasing after 5 years). This is a decreasing forest, so you subtract 4,000by 1,400.
