Answer:
73
Step-by-step explanation:
12(6) + 1/4 • 2^2
Square the 2 first.
12(6) + 1/4 • 4
Then multiply from left to right.
72 + 1
Lastly, add.
73
The parenthesis around the 6 mean multiplication, not the Parenthesis that are grouping symbols if you are learning PEMDAS. So your question has no grouping symbol parenthesis. Next comes Exponents, that's why we squared the 2. Multiply and Divide come next IN THE ORDER THAT THEY APPEAR FROM LEFT TO RIGHT. Then the same method with adding and subtracting. That's called the order of operations.
Answer:
Angle 1 = 80 (by definition)
Angle 3 = 180 - 80 = 100
Angle 4 + Angle 2 = 90
Also, Angle 2 = 40 (by definition)
So Anglee 4 = 50

Answer:
1 : 64
Step-by-step explanation:
Model:
1/2 in * 1/6 in = 1/12 in^2
Real:
1/3 ft * 1/9 ft = 1/3 * 12 in * 1/9 * 12 in = 16/3 in^2
model : real
1/12 / 16/3 = 1/12 * 3/16 = 3/192 = 1/64
model : real = 1 : 64
