A cubical box is filled with sand and weighs 510 N. It is desired to "roll" the box by pushing horizontally on one of the upper

edges. What minimum force (in newtons) is required? Any help is appreciated. Been at this for 30 minutes and I still don't get it.

Clockwise moments = Anticlockwise moments
Call the force you apply horizontally to the top left side of the square N.
W = 510 acting from the centre as the mass is distributed evenly.

Take moments about a pivot, in this case the bottom right corner is the pivot.
The clockwise moment is N and the anticlockwise moment is W.
N*x*sqrt(2) = 510*x/2
205x =Nx*sqrt(2)
205 = N*sqrt(2)
N = 205/sqrt(2)

Shelley receives supplies for her sno-cones business weekly. She usually works concession at four events a week and averages sal
My name is Ann [436]

Answer:

<u>Shelley did not budget enough. She will need additional US$ 16 for fulfilling the average sales of 760 sno-cones at the 4 events. With the budget she has, she just can supply 714 sno-cones (250 / 0.35).</u>

Step-by-step explanation:

1. Let's check all the information given for solving this question:

Cost of individual supply = US$ 0.35

Budget per week = US$ 250

Average sales of sno-cones per event = 190

Number of events per week = 4

2. Let's check if Shelley budgeted enough for the week events:

Total of sno-cones Shelley will sell = Average sales * Number of Events

Total of sno-cones Shelley will sell = 190 * 4 = 760

Cost of supplies for the week = Total of sno-cones * Cost of individual supply

Cost of supplies for the week = 760 * 0.35 = US$ 266

Budget per week = US$ 250

Budget per week  - Cost of supplies for the week = 250 - 266 = - 16

<u>Shelley did not budget enough. She will need additional US$ 16 for fulfilling the average sales of 760 sno-cones at the 4 events. With the budget she has, she just can supply 714 sno-cones (250 / 0.35).</u>

A flower vendor sells roses for 50 cents each. How much does she pay per flower is she makes $6.00 on every twenty dollars worth
Lelu [443]

One rose is 50 cents, so 2 roses cost $1 ( 50 cents x 2).

2 roses per dollar x 20 dollars = 40 total roses sold.


When they sell $20 dollars they make $6, so that means they pay 20-6 = $14 dollars for the 40 roses.


$14 / 40 roses = 0.35 per rose.

She pays 35 cents per rose.

Which is the simplified form of the expression (StartFraction (x Superscript negative 3 Baseline) (y squared) Over (x Superscrip
Vlad [161]

Answer:

The simplified form of the expression is \frac{1}{x^{7} y^{4}}.

Step-by-step explanation:

The expression is:

\frac{x^{-3}\cdot y^{2}}{x^{4}\cdot y^{6}}

The division rule of exponents is:

a^{m}\div a^{n}=a^{m-n}

The negative exponent rule is:

a^{-m}=\frac{1}{a^{m}}

Simplify the expression as follows:

\frac{x^{-3}\cdot y^{2}}{x^{4}\cdot y^{6}}=[x^{-3-4}]\times [y^{2-6}]

         =x^{-7}\times y^{-4}\\\\=\frac{1}{x^{7} y^{4}}

Thus, the simplified form of the expression is \frac{1}{x^{7} y^{4}}.

How to write eight ten-thousandths of thirty-five million in scientific notation?
VashaNatasha [74]
Eight ten-thousandths = 8*(1/10,000) = 8/10⁴ = 8 x 10⁻⁴.
Thirty-five million = 35*(1,000,000) = 35 x 10⁶

Therefore eight ten-thousandths of thirty-five million is
(8 x 10⁻⁴) * (35 x 10⁶)
= 280 x 10⁶⁻⁴
= 280 x 10²
= (2.8 x 10²) * 10²
= 2.8 x 10⁴

Answer:  2.8 x 10⁴
