Question about The Learning Company Achieve! Math & Science Grades 1-3 (381933) for PC, Mac

I need a weight loss formulas where I can enter weekly weight with a total of pounds loss.

Open excel and do the following...

A1: **Weekly Entry** B1: **Weekly loss** C1:**Total loss**

A2: Enter pound B2: Nothing Yet C2: Nothing Yet

A3: Enter pound B3:=if(a3="","",a2-a3) C3: =if(a3="",'',b3-b2)

Last thing you need to do is copy the cells A3,B3, and C3 and paste to the next row for every week.

Assuming the base of the pyramid is square ... of length B and the distance from the center of the base of the pyramid to the top of the pyramid is H

Surface area is: 2 x H x B

plus B-square (if you include the base of the pyramid)

Two ways to get to the same answer:

1) If X,Y, & Z are invested in the ratio of 4:5:6 then the amount invested in Z is 6/(4+5+6) times the total of N1200

= 6/15 * 1200

= N480

(Note: X is 4/15 and Y is 5/15 of the total investment,

4/15 + 5/15 + 6/15 = 15/15)

2) The second sentence says: Income from X plus income from Y minus income from Z is N140 and total income is N700. Total income is 700/1200 of the investment.

As formulas:

(Inc X + Inc Y) - Inc Z = 140 (rewriting: Inc X + Inc Y = 140 + Inc Z)

Inc X + Inc Y + Inc Z = 700

Substituting second formula into third:

(140 + Inc Z) + Inc Z = 700

140 + 2 Inc Z = 700

2Inc Z = 700 - 140 = 560

Inc Z = N280

Inc Z is also 700/1200 of investment in Z.

N280 = 700/1200 investment in Z

Investment in Z is 1200/700 * N280

Investment in Z is N480.

1) If X,Y, & Z are invested in the ratio of 4:5:6 then the amount invested in Z is 6/(4+5+6) times the total of N1200

= 6/15 * 1200

= N480

(Note: X is 4/15 and Y is 5/15 of the total investment,

4/15 + 5/15 + 6/15 = 15/15)

2) The second sentence says: Income from X plus income from Y minus income from Z is N140 and total income is N700. Total income is 700/1200 of the investment.

As formulas:

(Inc X + Inc Y) - Inc Z = 140 (rewriting: Inc X + Inc Y = 140 + Inc Z)

Inc X + Inc Y + Inc Z = 700

Substituting second formula into third:

(140 + Inc Z) + Inc Z = 700

140 + 2 Inc Z = 700

2Inc Z = 700 - 140 = 560

Inc Z = N280

Inc Z is also 700/1200 of investment in Z.

N280 = 700/1200 investment in Z

Investment in Z is 1200/700 * N280

Investment in Z is N480.

Here is how I would solve the problem starting from the expression for the gravitational acceleration as a function of the radius. You might not like the fact that I use SI units, but I will show you how to adapt my calculations to suit your needs.

The ratio of the acceleration at altitude h to the acceleration at sea level is a pure number (no dimensions). Just express the Earth radius and the altitude in the same units and your result will be correct.

To get the weight you can write

w(h)/w(at sea level)=g(h)/g, or

w(h)=150 lb* g(h)/g and your result will be in pounds.

Convert what you know into a couple of equations. You'll need two equations because there are two unknowns. Call them X = pounds of nuts that sell for .85/lb and Y = pounds of nuts selling for .55/lb.

Equation a): X+Y=60 (total weight sold is 60 lbs)

Equation b): .85X+.55Y=45.00 (because we want to sell 60 lbs at .75/lb)

Rearrange a) to X=60-Y (subtract Y from both sides)

Plug this into equation b) and solve it for Y:

.85X+.55Y=45.00

.85(60-Y)+.55Y=45.00

51.00 - .85Y + .55Y = 45.00

51.00 - .30Y = 45.00

6.00 = .30Y

Y = 6.00/.30 = 20 lbs

From equation a) then, X = 40 lbs. Check the results by solving equation b).

.85x40 + .55x20 = 34.00 + 11.00 = 45.00 (checks!)

(If either of those nuts is pistachios, where do I send my money? That's a good price and I want some!)

Equation a): X+Y=60 (total weight sold is 60 lbs)

Equation b): .85X+.55Y=45.00 (because we want to sell 60 lbs at .75/lb)

Rearrange a) to X=60-Y (subtract Y from both sides)

Plug this into equation b) and solve it for Y:

.85X+.55Y=45.00

.85(60-Y)+.55Y=45.00

51.00 - .85Y + .55Y = 45.00

51.00 - .30Y = 45.00

6.00 = .30Y

Y = 6.00/.30 = 20 lbs

From equation a) then, X = 40 lbs. Check the results by solving equation b).

.85x40 + .55x20 = 34.00 + 11.00 = 45.00 (checks!)

(If either of those nuts is pistachios, where do I send my money? That's a good price and I want some!)
