Which mathematical property is demonstrated 40•(25•74) = (40•25)•74

Sindrei [870]

The mathematical property that allows 40 * (25 * 74) = (40 * 25) * 74 would be the Associative Property of Addition and Multiplication. This property means that no matter how the values of an expression are grouped together (or "associating" with each other), the end result will be the same, as long as the symbols are all either multiplication or addition symbols.
Hope that helped =)

A particular rocket taking off from the earth surface uses fuel at a constant rate of 12.5 gallons per minute the rocket initial

faltersainse [42]

Answer:

$y=12.5x+225$

Step-by-step explanation:

Let

x ----> the number of minutes

y ----> the amount of fuel in gallons

we know that

The linear equation in slope intercept form is equal to

$y=mx+b$

where

m is the unit rate or slope

b is the y-intercept or initial value

we have that

The unit rate or slope is equal to

$m=12.5\ \frac{gal}{min}$

$b=225\ gal$ ----> initial value (value of y when the value of x is equal to zero)

substitute

$y=12.5x+225$

The quantity demanded x of a certain brand of DVD player is 3000/week when the unit price p is $485. For each decrease in unit p

Julli [10]

Answer:

a) Demand equation : $y=-\frac{2}{25}x+725$

b) Supply equation : $y=\frac{7}{100}x+350$

C) The equilibrium quantity and the equilibrium price are 2500 and $ 525 respectively

Step-by-step explanation:

We are given that For each decrease in unit price of $20 below $485, the quantity demanded increases by 250 units.

Since decrease in unit price of $20 increase demand by 250 units

So, Slope = $\frac{-20}{250}=\frac{-2}{25}$

We are given that The quantity demanded x of a certain brand of DVD player is 3000/week when the unit price p is $485.

Now for demand equation:

Use point slope form : $y-y_1=m(x-x_1)$

So, $y-485=\frac{-2}{25}(x-3000)\\y=-\frac{2}{25}x+725$

a)So, Demand equation : $y=-\frac{2}{25}x+725$

Now to find supply equation

We have two points (0,350) and (2500,525)

$(x_1,y_1)=(0,350)\\(x_2,y_2)=(2500,525)\\y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\y-350=\frac{525-350}{2500-0}(x-0)\\y-350=\frac{7}{100}x\\y=\frac{7}{100}x+350$

b) So, Supply equation : $y=\frac{7}{100}x+350$

Now to find equilibrium quantity and price equate demand and supply equation

$-\frac{2}{25}x+725=\frac{7}{100}x+350\\725-350=\frac{7}{100}x+\frac{2}{25}x\\x=2500$

So, equilibrium quantity = 2500

To find equilibrium price substitute equilibrium quantity in any equation

$y=\frac{7}{100}x+350\\y=\frac{7}{100}(2500)+350\\y=525$

C) The equilibrium quantity and the equilibrium price are 2500 and $ 525 respectively
