Answer:

Step-by-step explanation:

If she doubles the area of her lot, it should be 2x^2.

But how do you get that?

The answer is that the sides have now increased to √2x

How did I get that, and why did I choose it?

The formula for a square's area is s^2
If you want to double the area, it will be 2 s^2. Now what?
Take the square root of 2s^2 which is √(2s^2).
What that means is the side is now √2 s

Answer:

It will be 60 pixels high and 75 pixels wide

Step-by-step explanation:

$\frac{400}{60}=\frac{500}{x}$

The space allowed for the mascot on a school's Web page is 75 pixels wide by 60 pixels high
Its digital image is 500 pixels wide by 400 pixels high

So, the expression becomes

$\frac{400}{60}=\frac{500}{x}$

$\mathrm{Apply\:fraction\:cross\:multiply:\:if\:}\frac{a}{b}=\frac{c}{d}\mathrm{\:then\:}a\cdot \:d=b\cdot \:c$

$400x=60\cdot \:500$

$400x=30000$

$\mathrm{Divide\:both\:sides\:by\:}400$

$\frac{400x}{400}=\frac{30000}{400}$

$\mathrm{Simplify}$

$x=75$

Therefore, it will be 60 pixels high and 75 pixels wide

A woodworking artist makes two types of carvings: type X and type Y. He

ivolga24 [154]

Answer:

part C. 3x + 2y < 30, 5x + 7y < 105

Step-by-step explanation:

Part 1:

spends 3 hours making each type X (3x)-each type x will take 3 hours so as the number of type x increases, the hours will increase by 3.

spends 2 hours making each type Y (2y)-each type y will take 2 hours so as the number of type y increases, the hours will increase by 2.

Part 2:

he can spend up to 30 hours each week making carvings. (<30)-because he cannot spend more than 30 hours

Therefore, He has to spend 30 hours or less to make type X and type Y.

3x + 2y < 30

Part 3:

His materials cost him $5 for each type X carving. (5x)-each type x will take $5 so as the number of type x increases, the cost will increase by 5.

His materials cost him $7 for each type Y carving, (7y)-each type y will take $7 so as the number of type y increases, the cost will increase by 7.

Part 4:

he must keep his weekly cost for materials to $105 or less (<105)-total cost cannot be more than $105.

Therefore, the total cost of making x and y should be $105 or less.

5x + 7y < 105
