The answer is $2.25
I would use this proportion
24 / 3 18/x
18 times 3=54
54 divided by 24=2.25
X=$2.25
Answer:
Video game- 25
Bike riding - 18
Subtract them and you will get the answer.
= 7
Answer:
D.
Step-by-step explanation:
The factors of 121 are 1, 11 and 121.
The required temperature is 180K
<h3>Direct and inverse variation</h3>
Direct variation shows that when a variable is increasing or decreasing the other variable is also increasing/decreasing.
If the volume V of a fixed amount of a gas varies directly as the temperature T and inversely as the pressure P, this is expressed as
V = kT/P
Given that
V = 160 cm³ when T=320 kelvin and P = 12kg, hence;
160 = 320k/12
1 = 2k/12
2k = 12
k = 6
If V = 90 cm³ and P = 16kg/cm², then the value of the temperature is expressed as:
90 = 6T/16
15 = T/16
T = 15 * 16
T = 180K
Hence the required temperature is 180K
