Answer:

x =  \boxed{2}\:  and\: x =  \boxed{ \frac{5}{2} }

Step-by-step explanation:

2 {x}^{2}  - 9x + 10 = 0 \\  \\ 2 {x}^{2}  - 4x - 5x + 10 = 0 \\  \\ 2x(x - 2) - 5(x - 2) = 0 \\  \\ (x - 2)(2x - 5) = 0 \\  \\ x - 2 = 0 \:  \: 2x - 5 = 0 \\  \\ x =  \boxed{2} \: and \: x =  \boxed{ \frac{5}{2} } \\  \\

A bakery sells a giant decorated cookie for birthdays. The area of the cookie is about 113 square inches. What is the circumfere
umka21 [38]

Answer:

<em>38 inches</em>

Step-by-step explanation:

The cookies is in the shape of a circle. The formula for the area of a circle is:

A=\pi r^2

Where r is the radius

The area is given as 113, so we can find the radius:

A=\pi r^2\\113=\pi r^2\\r^2=\frac{113}{\pi}\\r=\sqrt{\frac{113}{\pi}} \\r=5.997

We need to find the circumference, which has the formula:

C=2\pi r

Where r is the radius (We got r = 5.997)

We substitute and find:

C=2 \pi r\\C = 2 \pi (5.997)\\C=37.68

So, the circumference is 37.68 inches.

<em>Rounded to nearest inch, that would be:</em>

<em>38 inches</em>

Minh wanted to measure the height of a statue. She lined herself up with the staues shadow so that the tip of her shadow met the
OLEGan [10]

The height of the statue is of 35 feet, applying similarity of triangles.

<h3>What are similar triangles?</h3>

Similar triangles are triangles that have congruent angle measures, thus the measures of their side lengths are proportional. This relation can be proven from the law of sines.

In the context of this problem, there are two similar right triangles, in which:

  • Minh's height of 5 feet is proportional to the statue's height of x.
  • The base formed by Minh's height, of 12 ft, is proportional to the base formed by the statue's height, of 84 ft.

Hence the following proportional relationship is established:

5/x = 12/84

Applying cross multiplication, it is found that:

12x = 84 x 5

Simplifying by 12, the expression is written as follows:

x = 7 x 5 (as 84/12 = 7).

x = 35 feet, which is the height of the statue.

A similar problem, also involving similarity of triangles, is presented at brainly.com/question/305520
