Answer:

d \propto \frac{s}{5}

Step-by-step explanation:

Given : The time between seeing the lightning and hearing the thunder is s seconds.

The distance d you are from lightning is approximately equal to one-fifth of s seconds.

To Find: Which direct variation equation represents this situation?

Solution:

d denotes the distance

s denotes The time between seeing the lightning and hearing the thunder

Since we are given that the distance d you are from lightning is approximately equal to one-fifth of s seconds.

\Rightarrow d \propto \frac{1}{5}\times s

\Rightarrow d \propto \frac{s}{5}

Hence the direct variation equation represents this situation is d \propto \frac{s}{5}

The direct variation that can be established using the given parameters is that, the time it takes between seeing the lightning and hearing the thunder is directly related to the speed. 

However, it can also be established that the time described above is inversely proportional to the distance. This can be written as,
         t = k/d
We substitute the given expression for each of the known terms. t is time, s, and d is distance, 3s. 

    s = k/3s

The k written in the equation is the constant of proportionality.

Steven just got a new summer job painting fences in his neighborhood. He will be paid $7.25 an hour. His first customer paid him
mote1985 [20]

Answer:

a). The equation; 7.25 h-36.25=0

b). total number of hours Steven work=5 hours

Step-by-step explanation:

Part A

The expression for the total money earned is as follows;

T=E×h

where;

T=total earnings

E=earnings per hour

h=number of hours worked

In our case;

T=$36.25

E=$7.25

h=h

replacing;

36.25=(7.25×h)

36.25=7.25 h

The equation would be; 7.25 h=36.25, or 7.25 h-36.25=0

Part B

7.25 h=36.25

h=36.25/7.25

h=5

total number of hours Steven work=5 hours

How to solve 4+|7-m|=5
notka56 [123]
When
|a|=b
assume
a=b and -a=b
so

4+|7-m|=5
minus 4 from both sides
|7-m|=1
assume
7-m=1 and
-(7-m)=1

7-m=1
minus 7 both sidees
-m=-6
times -1 both sides
m=6

-(7-m)=1
distribute
-7+m=1
add 7 to both sides
m=8

m=6 and 8
