In the top of the bird, you can see that the denominator was multiplied by 2. And whatever you do to the top, you have to do to the bottom. And whatever you do to the bottom, you have to do to the top. So multiply the numerator by 2 also. 4 x 2 = 8 so the answer is 8/2.

For the tail of the bird, you can see that it went from 8 to 56. Well what times 8 equals 56? 7. So it multiples the fraction by 7. So you want to multiply the 1 by 7 too. So you get the answer is 7/56.

You just repeat the same process on the other fractions. (:
If you need help with a specific fraction, just let me know! I'd be glad to help!

45-45-90 triangúlese shown<br><br> Help please <br><br><br> Will give u points
lbvjy [14]

Answer:

x = 7 , y = 7\sqrt{2}

Step-by-step explanation:

A 45- 45- 90 triangle is an isosceles right triangle with the 2 legs being congruent , that is

x = 7

Using Pythagoras' identity in the right triangle, then

y² = 7² + 7² = 49 + 49 = 98 ( take square root of both sides )

y = \sqrt{98} = \sqrt{49(2)} = \sqrt{49} × \sqrt{2} = 7\sqrt{2}

The inequality is 4 ≥ x/2.1, and the answer is 8.4 ≥ x (or x ≤ 8.4).

To solve this, we multiply both sides by 2.1:
4*2.1 ≥ x
8.4 ≥ x.

The length of the rectangle is three times its width.The perimeter of the rectangle is at most 112 cm .
Slav-nsk [51]

Option D is the correct answer

2w+2.(3w)\leq 112

Further explanation:

Let

l\ be\ the\ length\ of\ rectangle\\and\\w\ be\ the\ width\ of\ rectangle

The perimeter of a rectangle is given by:

P=2w+2l

It is also given that:

P\leq 112

So we can write as

2l+2w\leq 112

We also know that The length of the rectangle is three times its width

l=3w

Putting the value of l in the inequality

2.(3w)+2w\leq 112

Rearranging the terms

2w+2.(3w)\leq 112

Hence, option D is the correct answer.
