David made a scale drawing of an Olympic-sized pool the pool is 20.5 in long and the drawing that I can shoot pool is 164 ft lon

SIZIF [17.4K]

Answer:

$Scale = 1\ in : 8\ ft$

Step-by-step explanation:

Given

$Scale\ Measurement = 20.5in$

$Actual\ Measurement = 164ft$

Required

Determine the scale

The scale is calculated using the following ratio:

$Scale = Scale\ Measurement : Actual\ Measurement;$

Substitute values for Scale and Actual Measurements

$Scale = 20.5\ in : 164\ ft$

Divide ratio by 20.5

$Scale = 20.5/20.5\ in : 164/20.5\ ft$

$Scale = 1\ in : 8\ ft$

This implies that: <em>1 inch on scale represents 8 ft in actual measurement</em>

I need someone to teach me how to do at least half of these problems please help

Gwar [14]

Here, You need to substitute the value of x, and y, in the equation then check if L.H.S is equal to R.H.S or not. If they are equal then, ordered pair was correct, otherwise they are not applicable.

75) Here, oly option D can fit i the equation, we can check:
3(-5) -2(-1) = -15+2 = -13 = R.H.S
So, the pairs are valid.

76) Here, only option D is your answer,
4(2) - 4 = 8 - 4 = R.H.S

Do the same thing in every equation!

Hope this helps!

What is the perimeter (in inches) of a television screen that measures 24 1/2 in. by 40 in.?

Bess [88]

The perimeter of the television screen (in inches) is 129 inches.

Given that a television screen in the shape of a rectangle has a length of 40 inches and breadth $\frac{49}{2} inches$ .

Perimeter of rectangle=2(length of rectangle+ bredth of rectangle)

Here the TV screen is the shape of rectangle

Therefore Perimeter of TV screen=perimeter of rectangle

Given the the length of TV screen=40 inches

The bredth of the TV screen= $\frac{49}{2} inches$ .

Perimeter of TV screen=2(40 inches + $\frac{49}{2} inches$ )

Perimeter of TV screen=(80+49) inches

Perimeter of TV screen= 129 inches

Therefore,The perimeter of the television screen (in inches) is 129 inches.
