Answer:
|x|=6 we have x1=-6 x2=6
|x|=3.2 we have x1=-3.2 x2=3.2
|x|=0 x=0
The answer is 32 8 times 4 would equal 32
Answer:
3
Step-by-step explanation:
A ball is 10 meters. Since 100 centimeters are in a meter, each ball has 100*10 = 1000 centimeters.
The teacher needs 70 strings each 40 centimeters. The total amount they need is 70*40 = 2800 centimeters.
Since a ball has 1000 centimeters, 2800 centimeters will need 3 balls for a total of 3000 centimeters.
Answer:
1131.0 m³
Step-by-step explanation:
Using the formula for the volume of a cylinder, fill in the appropriate values and do the arithmetic.
V = πr²h
Since this formula needs the radius of the cylinder and you are given the diameter, you must divide the diameter by 2 to get the radius:
r = d/2 = (12 m)/2 = 6 m
Then the volume is ...
V = π(6 m)²(10 m) = 360π m³ ≈ 1131.0 m³ . . . . . rounded to tenths
