Answer:
68. See pic
Step-by-step explanation:
The value of the unknown length is 24
<h3>How to determine the
unknown length?</h3>
Represent the unknown length with x.
So, we have the following equivalent ratio:
30 : 30 + x = 25 : 45
Express as fraction
30/30 + x = 25/45
Simplify the fraction
30/30 + x = 5/9
Cross multiply
150 + 5x = 270
Evaluate the like terms
5x = 120
Divide by 5
x = 24
Hence, the value of the unknown length is 24

What is the question here.
(1/2)(X+Y)-(1/3)
<em>≈ 24 cm</em>
- <em>Step-by-step explanation:</em>
<em>Hi there !</em>
<em>c = 2πr } => c = πd => d = c/π</em>
<em>2r = d</em>
<em>replace c ; π</em>
<em>π =3.14</em>
<em>d = 74cm/3.14</em>
<em>= 23.5668</em>
<em>≈ 24 cm</em>
<em>Good luck !</em>
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
