Answer:

  1. 784 ft²
  2. 1 cm² : 16 ft²

Step-by-step explanation:

Since we need the ratio of drawing area to floor area to figure the actual floor area, it is convenient to answer the questions in reverse order.

The ratio of drawing area to actual area is ...

... ((1 cm)/(4 ft))² = (1 cm²)/(16 ft²)

____

Then the actual floor area is ...

... (16 ft²)/(1 cm²) = actual area/(49 cm²)

Multiplying by 49 cm² gives ...

... (16 ft²)*49/1 = actual area = 784 ft²

The shorter leg of the right triangle is 8 less than the hypotenuse. The longer leg is 1 less than the hypotenuse. Find the peri
Wewaii [24]
Hypotenuse = h
leg1 = h-8
leg2 = h-1

h² -(h-8)² = (h-1)²

h² - [h² -16h +64] = h² -2h +1
16h -64 = h² -2h +1
h² -18h + 65 = 0

hypotenuse = 13
leg1 = 13-8 = 5
leg2 = 13-1 =12

Perimeter = 13 + 5 + 12 = 30

Determine if the statement is always, sometimes or never true.
Romashka-Z-Leto [24]

Let

x--------> the measure of the adjacent interior angle

y--------> the measure of an exterior angle at the vertex of a polygon

we know that

The measure of the adjacent interior angle and the measure of an exterior angle at the vertex of a polygon are supplementary angles

so

x+y=180°

<u>Examples</u>

case 1)

<u>In a square</u>

x=90°

so

y=180-90=90°

x=y

In this case

The measure of an exterior angle at the vertex of a polygon equals the measure of the adjacent interior angle

case 2)

<u>an equilateral triangle</u>

x=60°

so

y=180-60=120°

x\neq y

In this case

The measure of an exterior angle at the vertex of a polygon is not equals the measure of the adjacent interior angle

therefore

<u>the answer is</u>

sometimes
