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

Re: Mathematical Calculation

Following formula we can use.

S=P(1+RT)

WHERE S =INVEST AMOUNT+PROFIT

P=INVEST AMOUNT

R= RATE OF RETURN

T=TIME IN YEARS

EX : (300+x) = x(1+(5.4/100)*1)

(300+x)*100 = 105.4x

x=30000/5.4

x=5555. 4

Assuming you are in the USA and use these units:

W is your weight in pounds

H is your height in inches

BMI = W / H^2 x 703.

So if your height is 5' 10" (70") and weight is 180 lbs

BMI = 180 / (70 x70) x 703 = 25.82

So <18.5 is thin

18.6 to 24.9 is healthy

25 to 29.9 is overweight

>30 is obese

W is your weight in pounds

H is your height in inches

BMI = W / H^2 x 703.

So if your height is 5' 10" (70") and weight is 180 lbs

BMI = 180 / (70 x70) x 703 = 25.82

So <18.5 is thin

18.6 to 24.9 is healthy

25 to 29.9 is overweight

>30 is obese

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.

Definition

A mathematical statement used to evaluate a value. An equation can use any combination of mathematical operations, including addition, subtraction, division, or multiplication. An equation can be already established due to the properties of numbers (2 + 2 = 4), or can be filled solely with variables which can be replaced with numerical values to get a resulting value. For example, the equation to calculate return on sales is: Net income รท Sales revenue = Return on Sales. When the values for net income and sales revenue are plugged into the equation, you are able to calculate the value of return on sales.

There are many types of mathematical equations.

1. Linear Equations y= mx + b (standard form of linear equation)

2. Quadratic Equations y= ax^2+bx+c

3. Exponential Equations y= ab^x

4. Cubic Equations y=ax^3+ bx^2+cx+d

5. Quartic Equations y= ax^4+ bx^3+ cx^2+ dx+ e

6. Equation of a circle (x-h)^2+(y-k)^2= r^2

7. Constant equation y= 9 (basically y has to equal a number for it to be a constant equation).

8. Proportional equations y=kx; y= k/x, etc.

This is a mathematical notation for a function of a variable x.

Let there be two quantities say the number of hours worked per week (x) and the salary you get paid (y).

The number of hours you work is the independant variable. The salary paid is the dependant variable.

For each amount of hours you work, your boss calculates the salary that is owed you at the end of the week. The method your boss uses to calculate your salaray is the function.

Symbolically, this can be represented as

Salary ($)=f(hours vorked) or

y=f(x)

For example: if the hourly rate is 8$/h and you work 35h then what is owed you is

35h*8$/h=280$

If you work more hours you will get more pay and if less hours, less pay

The rule is y=8*x

First, you need to get the probability of the two events - not enough rain and enough rain.

The probability of not enough rain is 1 less the probability of enough rain.

Supposing that the probability of not enough rain is 0.70, then the probability of enough rain is 0.30.

Therefore to get the profit per acre, you multiply these probabilities with their profits per acre. Hence,

$4000 * 0.30 + $1600 * 0.70 = $2,320 is the average profit per acre.

The above method uses the mathematics principle of the weighted expected returns.

I hope this helps.
