Yes, the gcf of even numbers would always be even because both of the numbers are divisible by 2 which makes 2 a factor of both the numbers, so the gcf should be even too.

Yes becaus any even numbers can be represented as 2n where n is an integer

so 2n and 2m where m and n aer both integers
they both have 2 as a factor so that will be included in finding the greatest common factor

Differentiating with respect to time

Basic Power Rule:

f(x) = cxⁿ
f’(x) = c·nxⁿ⁻¹

Step-by-step explanation:

Step 1: Define

$l = 30 \ cm\\w = l\\\frac{dl}{dt} = 2 \ cm/h\\h = 20 \ cm\\\frac{dh}{dt} = 3 \ cm/h$

Step 2: Differentiate

Rewrite [VRP]: $V = l^2h$
Differentiate [Basic Power Rule]: $\frac{dV}{dt} = 2l\frac{dl}{dt} \frac{dh}{dt}$

Step 3: Solve for Rate

Substitute: $\frac{dV}{dt} = 2(30 \ cm)(2 \ cm/h)(3 \ cm/h)$
Multiply: $\frac{dV}{dt} = 360 \ cm^3/h$

Here this tells us that our volume is decreasing (ice melting) at a rate of 360 cm³ per hour.

Find each absolute value. |6-3|

Vitek1552 [10]

When you take the absolute value of this equation, the answer should actually be 3.

You should solve the what’s inside first. If the answer is negative, then the absolute value will make it positive.

For example

|1-5|=|-4|=4

Joe borrowed $8,000 on a one year note at 13%. How much will Joe owe when the note comes due? 1040 wasn't right.

SpyIntel [72]

$8,000 x 0.13 = $1040

$8,000 + $1040 = $9,040

it takes 40 minutes for 8 people to paint 4 walls. How many minutes does it take 10 people to paint 7 walls?

KIM [24]

First let's find the rate at which one person paint one wall. We know it takes 40 minutes for 8 people to paint 4 walls.

If we divide 40 minutes by 4 walls, we find that it takes 8 people 10 minutes to paint ONE wall. Next, we multiply 10 minutes per wall by 8 people to find how long it takes ONE person to paint ONE wall. Since it takes 8 people 10 minutes, reducing the number of people to one will increase the required time by a factor of 10. So it takes ONE person 80 minutes to paint ONE wall.

Now let's use this information to find out how long it takes 10 people to paint 7 walls. First, multiply 80 minutes by 7 since there are 7 times as much wall to paint. We now know that it takes 560 minutes for one person to paint 7 walls. Finally, divide 560 minutes by 10 people.

The answer is 56 minutes.
