3/10n = 4/5
n = (4/5)/(3/10)
n = 4/5 * 10/3
n = 8/3
n = 2 2/3
Answer:
2x² + 6x + 4
= 2(x² + 3x + 2)
= 2(x² + 2x + x + 2)
= 2[x(x + 2) + (x + 2)]
= 2(x + 1)(x + 2)
Step-by-step explanation:
Answer: 0.44mm
Step-by-step explanation:
In this problem we are asked for the height of a single playing chip. We know the volume of a cylinder is 25120 mm^3.
V=πr²h
25120=πr²h
The problem also gives the diameter of the case: 40mm.
To find radius, you divide the diameter in half.
d=2r
40=2r
r=20
With the radius, we can add that to the volume equation.
25120=
(20)^2h
25120=400πh
All we have left is to find the height.
h=25120/(400π)
h≈20mm
Now that we know the height, we can find the height of a single chip. The problem states about 50 chips can fit in a case. To find the height of a single chip, you would divide 20 by 50.
20mm/50 chips=0.4mm/chip.
Answer:
the 360 g is the best deal because it is 1.28 per 1g
Step-by-step explanation:
Convert $4.10 and $2.81 to pennies
To do that we multiply them by 100 since there are 100 pennies per $1.
$4.10 x 100 = 410¢
540g/410¢ = 1.41¢
1.41 rounded is 1¢
then
multiply $2.81 x 100 = 281¢
360g/281¢ = 1.28 rounds to 1¢
