the volume of a 15oz cereal box is 180.4in cube. the length of the box is 3.2 in. less than the height and the width is 2.3 in. find the height and length of the box to the nearest tenth.

Answers

The height and length of the box to the nearest tenth will be 10.6 inch and 7.4 inch respectively.

Explanation

Suppose, the height of the box is $h$ inch

As the length of the box is 3.2 in. less than the height, so the length will be: $(h-3.2) inch$

Given that, the width of the box is 2.3 inch. and the volume is 180.4 inch³

Formula for Volume of a box: $V= length*width*height$

So, the equation will be....

$(h-3.2)*2.3*h = 180.4\n \n 2.3h^2 -7.36h=180.4\n \n 2.3h^2-7.36h-180.4=0$

Now using quadratic formula......

$h=(-b+/-√(b^2-4ac))/(2a)\n \n h= (-(-7.36)+/-√((-7.36)^2-4(2.3)(-180.4)))/(2(2.3))\n \n h= (7.36+/-√(1713.8496))/(4.6) \n \n h=(7.36+/-41.398...)/(4.6) \n \n h= 10.599... or -7.399...$

(Negative value of $h$ is ignored as the height can't be negative)

So, the height to the nearest tenth will be 10.6 inch and the length will be: $(10.6-3.2)inch= 7.4 inch$

Part A How much voltage must be used to accelerate a proton (radius 1.2 ×10−15m) so that it has sufficient energy to just penetrate a silicon nucleus? A silicon nucleus has a charge of +14e, and its radius is about 3.6 ×10−15m. Assume the potential is that for point charges.

Answers

Answer:

Step-by-step explanation:

Qp = charge on proton = 1.6 x 10-19 C

Qs = charge on silicon = 14 x 1.6 x 10-19 C

rf = final distance from nucleus = ∞

ri = initial distance from nucleus = (3.6 x 10-15 + 1.2 x 10-15 ) = 4.8 x 10-15 m

initial Potential energy is given as

Ui = k Qp Qs / ri = (9 x 109) (1.6 x 10-19 ) (14 x 1.6 x 10-19 ) / (4.8 x 10-15 ) = 6.72 x 10-13 J

final Potential energy is given as

Uf = k Qp Qs / rf = (9 x 109) (1.6 x 10-19 ) (14 x 1.6 x 10-19 ) / (∞) = 0 J

Change in Potential energy = ΔU = Ui - Uf = 6.72 x 10-13 - 0 = 6.72 x 10-13 J

Let the Voltage through which proton is accelerated = V

Energy gained due to potential difference = Qp V

Using conservation of energy

Qp V = 6.72 x 10-13

(1.6 x 10-19 ) V = 6.72 x 10-13

V = 4.2 x 106 volts

John ordered five large size pizzas for a party. Five kids each ate 1/10 slice, and twelve adults each at 3/10 slices.a) Find the total number of slices consumed.
41/10
b) Find the leftover pizza if any.

Answers

Answer:

a) 4 1/10 slices eaten

b) cannot be solved because we don't know how many slices in each pizza

Step-by-step explanation:

5*1/10=5/10

12*3/10=36/10

36/10+5/10=41/10

41/10=4 1/10 slices
