On a particular Saturday, 60% of the visitors to an art museum were students. If 144 visited the museum, how many total visitors

Bad White [126]

Answer:

240 visitors

Step-by-step explanation:

We are given the following in the question:

Percentage of visitors that are student to art museum = 60%

Total number of students to museum = 144

We have to find the total number of visitors to the museum.

Let x be the total number of visitors to the museum.

Thus, we can write the equation:

$60\%\times x = 144\\\\\dfrac{60}{100}\times x = 144\\\\\Rightarrow x = 144\times \dfrac{100}{60}\\\\\Rightarrow x = 240$

Thus, there were 240 visitors to the art museum on that day.

Vance wants to determine if an old photo frame is still rectangular. The height of the frame is

sveticcg [70]

Answer:

<em>The old photo frame is still rectangular</em>

Step-by-step explanation:

<u>Rectangles</u>

The rectangle shape can be identified because it has 4 internal angles of 90° each. The diagonal forms with two adjacent sides a right triangle where the Pythagora's Theorem must stand. Being a and b the length of the sides of the rectangle and d the diagonal, then:

$d^2=a^2+b^2$

Vince's photo frame has dimensions of 8 inches and 6 inches, with a diagonal of 10 inches. If the above condition is met, then the frame is still rectangular.

Calculating:

$10^2=6^2+8^2$
