<span>Sarafina accurately completed 34.3434% of the hits assigned to her. Also you could say that I hit 3.4 out of every 10 hits I make.</span>
The rate of the machine is 10 boxes per min.
Step-by-step explanation:
Given,
A machine can make 150 boxes in 15 min
To find the rate of the machine
Meaning to find the number of boxes machine it can make in 1 min
We will apply unitary method.
In 15 min it makes 150 boxes
In 1 min it makes (150÷15) boxes = 10 boxes
Hence the rate is 10 boxes per min.

Answer:
Part a) The fraction is 
Part b) The percent is 
Step-by-step explanation:
Part a)
Find the fraction
we know that
To find the fraction of the shaded part in the square divide the number of shaded squares by the total number of squares
so
Let
x-------> the number of shaded squares
y-------> the total number of squares
f-------> the fraction of the shaded part
so

In this problem we have


substitutes

Simplify

Part b) Find the percent
To find the percent multiply the fraction by 100
so

convert to mixed number

The wave length of the sound with parameters frequency of 125 Hz and a speed 5000 m/s is 40 meters
<h3>Given Data</h3>
velocity = 5000 m/s
frequency = 125 Hz
wavelength = ??
We know that the relationship between speed, frequency and wavelength is given as
v = fλ ----------------------------1
substitute our given parameters
5000 = 125 * λ
Divide both sides by 125
λ = 5000/125
λ = 40 m
Hence the wave length of the sound is 40 meters
