The arc measure of AD in degrees is 43 degrees.
<u>Step-by-step explanation</u>:
- The angle measure of the straight line is 180°.
- ∠APD + ∠DPC + ∠CPB = 180°
⇒ (7x+1)° + 90° + (9x-7)° = 180°
⇒ 16x + 84° = 180°
⇒ 16x = 96°
⇒ x = 96/16
x = 6
Substitute x=6 for angle ∠APD = (7x+1)°
∠APD = 7(6)+1 = 43°
The arc measure of AD in degrees = 43 degrees.
Answer: A
Step-by-step explanation:
Answer:
a. 1 inch = 3 feet
b. 1 inch
Step-by-step explanation:
In the figure attached the drawing of the bench is shown correctly.
a.
The drawing shows that the width of the bench is 2 inches. To get the scale we need to divide actual width by drawing width, in mathematical terms:
scale = 6 feet/2 inches = 3 feet/inch
b.
If actual height is 3 ft and every inch represents 3 feet, then, the height of the scale drawing is 1 inch
volume = l x w x h
so 4 x 2 x 8 = 64 cubic inches per brick
64 x 3 = 192 cubic inches total
Answer:
THE answer is D Irrational number
Step-by-step explanation:
Pi is an irrational number because it cannot be expressed as a ratio (fraction) of two integers: it has no exact decimal equivalent, although 3.1415926 is good enough for many applications. The square root of 2 is another irrational number that cannot be written as a fraction.
