In order to join a flying club,there is a $200 annual fee and $20 a month fee to maintain the flying club runaway.Write an equat

Fudgin [204]

Answer:

The equation modelling the situation is $T=200+20m$ .

After <u>10 months</u> the cost would be $400.

Step-by-step explanation:

Given:

Annual Fee of flying club = $200

Monthly fee = $20

We need to write an equation for total cost.

Solution:

Let the number of months be denoted 'm'

Let Total cost be denoted by 'T'

Now we can say that:

Total cost is equal to sum of Annual Fee of flying club plus Monthly fee multiplied by number of months.

framing in equation form we get;

$T=200+20m$

Hence The equation modelling the situation is $T=200+20m$ .

Now given:

We need to find the number of months when total cost will be $400

So we will substitute T= 400 in above equation.

$200+20m=400$

Subtracting both side by 200 we get;

$200+20m-200=400-200\\\\20m=200$

Dividing both side by 20 we get;

$\frac{20m}{20}=\frac{200}{20}\\\\m=10 \ months$

Hence After <u>10 months</u> the cost would be $400.

Please help me!!!!! :)

To find the volume,we would first need to find the height of square pyramid, by it's base edge and slant height using Pythagoras theorem:

${height }^{2} = {13}^{2} - {10}^{2} \\ {height }^{2} = 69 \\ height = \sqrt{69}$

We can then use the pyramid formula to find the volume:
$base \: \times \: height \: \times \frac{1}{3}$

In this case,the volume will be:

10×_/69×1/3
=27.68874...
≈27.7 units^3

Hope it helps!

jackson owns his sister monica monica has a $10 im her pocket explain the meaning of zero in this situation

liq [111]

The meaning of the 0 in this situation is that the 0 is there as a place holder. It is there to support the 1 so it has a bigger value instead of just 1.

a tennis supply store pays a wholesaler $90 for a tennis racquet and sells it for $144 what is the markup rate

dexar [7]

Markup is the difference between the cost of a good or service and its selling price. A markup is added onto the total cost incurred by the producer of a good or service in order to create a profit. The total cost reflects the total amount of both fixed and variable expenses to produce and distribute a product.so it would be 144 - 90 = 54. $54 would be the markup.
