Answer:

Step-by-step explanation:

An negative exponent seems hard, but it really isn't!

Let's say you have $2^{-3}$

All you do is inverse the expression, or find the reciprocal. When you do this the exponent changes to positive .

$\frac{1}{2^{3} }$

$2^{3}$ simplifies into 8. So, the result is

$\frac{1}{8}$

Hope this helps! Please mark as brainliest, thanks!

Predict: How do you think the formula for area of a triangle will relate to the formula for area of a rectangle? Do you

Answer:

I think is the same formula area .A triangle is half as big as the rectangle that surrounds it, which is why the area of a triangle is one-half base times height.

Step-by-step explanation:

The area of a rectangle is given by the relation length* width. The area of a triangle is given by the relation (1/2)*base* height. Now we know that the two have the same area equal to 150 cm^2. Also, when placed on the same level the tip of the triangle touches the upper edge of the rectangle.

A nearby pool holds 30,000 gallons. The pool has been filled with 19,500 gallons of water. If the variable w stands for the amou

Nataly_w [17]

30,000 - 19,500 = 10,500 gallons left to fill the pool. So I am assuming the answer would be w = 10,500 gallons... unless there was an equation missing in the question

I believe it would be dilated by 3/4

If you think of a rectangle, let’s say it is 8 by 4, the perimeter of this rectangle would be 24.

Now if you dilate the side values, you get 6 by 3 and the perimeter equals 18

So you then get 18/24 which is equal to 3/4

Hope this is right and makes sense! Have a good day!

Answer:

1. new perimeter = 4 times the old perimeter

2. The area will go up by a factor of 16

3. The new area is 1/9 of the original area.

Step-by-step explanation:

1. side length1 = x

side length2 = y

2x + 2y = perimeter

2(4x) + 2(4)y = new perimeter

8x + 8y = new perimeter

new perimeter = 4 times the old perimeter

2. The area will go up by a factor of 16. This is because the area formula has them being multiplied together and thus it will make the area go up by that much.

3. Let the length of the rectangle be x

Let width of rectangle be y

Area of rectangle = L*W

Now Each side length of the rectangle is multiplied by 1/3

So, new area = (1/3)L * (1/3)W

=(1/9)LW

So, the new area is 1/9 of the original area.
