Answer:
60 + .20*120= 84
10 + 120/10*.10= 11.20
90 - 60 + 30/.20 = 180
Step-by-step explanation:
Answer:
2 and -2
Step-by-step explanation:
● 7q^2 -28 = 0
Add 28 to both sides
● 7q^2-28+28 = 28
● 7q^2 = 28
Divide both sides by 7
●7q^2/7 = 28/7
● q^2 = 4
You can write directly q= 2 or q= -2
To understand it use the absolute value.
● |q| = 2
● q = 2 or q = -2
The solutions are {2, -2}
It is a rational number
the fraction is 5877 / 1000
What's the question I don't understand
Answer: 401.9
Step-by-step explanation:
Formula for volume of sphere is 4/3πr^3 = 4
r^3 = 64
4/3 x 3.14 = 6.28
6.28 x 64 = 401.92
Rounded to the tenth is 401.9
