Answer: There are 12 bills for $20, 13 bills for $10 and 14 bills for $5.
Step-by-step explanation:
Let the number of twenties be x
Let the number of tens be x+1
Let the number of fives be x+2
Amount from twenties will be given as
Amount from tens will be given as
Amount from fives will be given as
According to question,
So, there are 12 bills for $20, 13 bills for $10 and 14 bills for $5.
Answer:
-22 ≤ temperature(F) ≤ 266
Step-by-step explanation:
Given that,
The label on the car's antifreeze container claims to protect the car between -30C and 130C.
Formula to convert Celsius temperature to Fahrenheit
<h3>C = 5/9 (F - 32)</h3><h3>9C/5 = (F - 32)</h3><h3>9C/5 + 32 = F</h3><h2>F = 9C/5 + 32 </h2><h3>1)</h3>
-30C = ?F
F =9(-30)/5 + 32
F = -22
<h3>2)</h3>
130C = ?F
F =9(130)/5 + 32
F = 266
The inequality to determine the Fahrenheit temperature range at which this antifreeze protects the car is
<h3>-22 ≤
temperature(F) ≤ 266</h3>
Answer:21/7
Step-by-step explanation:
It depends on the type of graphing calculator u have
Answer: 4.51 cm
Step-by-step explanation:o Area of circle=pi×r^2
Given area=64 cm sq.
so, 64=3.14×r^2
64/3.14= r^2
20.38= r^2
√20.38=r
4.51=r
Therefore, radius= 4.51 cm
