I think B gives the best estimate and exact product because
1). 5.9 x 8.28 is very similar to 6 x 8 which equals 48.
and
2. 5.9 x 8.28 = 48.852.
Hopefully that made sense. :)
Basing on the question the volume of metal should be equal to the volume of the wire.
We already have the volume of the metal which is 1cm cube.
To get the volume of the wire, the equation is V=3.14 x r^2 x h
since the volume of the wire is same as the volume of the metal, we simply substitute.
1 cm^3 = 3.14 x r^2 x h
h is the length of the wire.
the diameter of the wire is 1 mm or 0.1 cm, to get the radius we divide it by 2, 0.1 cm / 2 is 0.05 cm, we substitute
1 cm^3= 3.14 x (0.05 cm)^2 x h
1 cm^3= 3.14 x 0.0025 cm^2 x h
h = 0.00785 cm^2 / 1 cm^3
h=0.00785 cm or 0.0785 mm.
Answer: 280
<u>Step-by-step explanation:</u>
Quantity X Cost = Money Received
Adult: x 3 3x
Children: 500-x 2 2(500 - x) = 1000 - 2x
Adult = Children + 400
3x = 1000 - 2x + 400
3x = 1400 - 2x
5x = 1400
x = 280
At this point in time, you can use a technique called cross-mutiplication, where you say that
, and
at this point in time, you can devide each side by 8 and solve
Answer:
1
Step-by-step explanation:
you move the decimal to the right twice, so it goes from .01 to 1.00 if that makes sense :)
