48,96,192
Step-by-step explanation:
We see that each term is twice of the previous term. Using this principle, we get the next three terms, which are 48,96,192.
Answer:
x=0 or x=−5
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3x^2+15x=0
Step 2: Factor left side of equation.
3x(x+5)=0
Step 3: Set factors equal to 0.
3x=0 or x+5=0
x=0 or x=−5
Answer:
pretty sure its the first one
Step-by-step explanation:
Answer:
It's on the negative side, so make sure you put -2.25. But yes, it's right.
Answer:
17.8 cm³
Step-by-step explanation:
The radius of the roll is half the diameter, so is 9 mm. The length of the roll of 50 dimes is 1.4·50 mm = 70 mm. With these dimensions, we can use the formula for the volume of a cylinder:
V = πr²h = π(9 mm)²(70 mm) = 5670π mm³ ≈ 17,812.8 mm³
Perhaps a more convenient unit of measure is cm³. Each cm³ is 1000 mm³, so the volume of a roll of dimes is approximately ...
V ≈ 17.8 cm³
