Answer:
D. 40
Step-by-step explanation:
First, calculate the total time she took in seconds.
Convert minutes to seconds using 60 seconds = 1 minute
2 min X 60 s = 120 s
Total time = 120 s + 42 s = 162 s
Calculate the total number of laps.
Convert metres to laps using 50 metres = 1 lap
Laps = 200 m ÷ 50 m = 4 laps
Divide the total time by the number of laps to calculate the unit rate, which is time per one lap.
Since it says to <u>estimate, round 162 seconds</u>.
162 s ≈ 160 s
160 s ÷ 4 laps ≈ 40s/lap
Her estimated time per lap is 40s.
They are placed in descending order of degree.

The value of function f(x) = x+4 when x=3 is 7.
By considering given function
f(x) = x+4
f(3)= 3+4
f(3)=7
A mathematical expression, rule, or law that establishes the relationship between an independent variable and a dependent variable (the dependent variable). In mathematics and the sciences, functions are fundamental for constructing physical relationships.
Four broad categories can be used to classify different types of functions. One to one function, many to one function, onto function, one to one and into function—all based on the element.
