Dvinal [7]

Question: Which situation is represented by $\frac{25}{9}$ ?

Option A: Melanie equally shares 25 meters of paper to create 9 banners

Option B: Quill gives way 9 baseball cards from a pack of 25 cards.

Option C: George invites 25 kids and 9 adults to his birthday party.

Option D: Becca create 9 rows with 25 buttons.

Answer:

Solution:

Option A: Melanie equally shares 25 meters of paper to create 9 banners.

The fraction is $\frac{25}{9}$ .

Option B: Quill gives way 9 baseball cards from a pack of 25 cards.

The fraction is $\frac{9}{25}$

Option C: George invites 25 kids and 9 adults to his birthday party.

Here, 25 + 9.

Option D: Becca create 9 rows with 25 buttons.

Here, 9 × 25.

Hence the answer is Option A: Melanie equally shares 25 meters of paper to create 9 banners.

What must be the sides of an equilateral triangle so that it's area should be equal to the area of an isosceles triangle with ba

d1i1m1o1n [39]

Answer:

The sides of the equilateral triangle are 11.7 m.

Step-by-step explanation:

Let's find the area of the isosceles triangle:

$A_{i} = \frac{bh}{2}$

Where:

b: is the base = 12 m

h: is the height

We can find the height by using Pitagoras:

$x^{2} = \frac{b^{2}}{2} + h^{2}$

Where:

x is the hypotenuse = side of the triangle = 10 m

$h = \sqrt{x^{2} - \frac{b^{2}}{2}} = \sqrt{(10)^{2} - 6^{2}} = 8 m$

Then, the area is:

$A_{i} = \frac{12*8}{2} = 48 m^{2}$

Now, since the area of the isosceles triangle is equal to the area of the equilateral triangle:

$A_{e} = A_{i} = 48 m^{2}$

$A_{e} = \frac{bh}{2}$

The height of the equilateral triangle is given by:

$b^{2} = \frac{b^{2}}{2} + h^{2}$

$h = \sqrt{b^{2} - \frac{b^{2}}{2}} = \frac{b}{\sqrt{2}}$

Hence, the sides are:

$A_{e} = \frac{1}{2}b\frac{b}{\sqrt{2}} = \frac{b^{2}}{2\sqrt{2}}$

$b = \sqrt{A*2\sqrt{2}} = \sqrt{48*2\sqrt{2}} = 11.7 m$

Therefore, the sides of the equilateral triangle are 11.7 m.

I hope it helps you!
