Step-by-step explanation:
This is an order of operations problem. II'll use using PEMDAS here:
- P: Evaluate expressions in parenthesis first
- E: Evaluate terms with exponents
- MD: Evaluate multiplication and division from left to right
- AS: Evaluate addition and subtraction from left to right
Parenthesis first. The first expression in parenthesis is already as simplified as it gets, so up next is the second one:
There are no parenthesis and there are no exponents, so do the multiplication first.
Back to the original expression and we now have:
Exponents comes next:
Now we have:
Multiplication comes next:
Finally, addition.

You can just put this into a calculator:
1/2^2 = 0.25
3×5-3 = 12
1^3 = 1
0.25 × 12 + 1 = 4

Step-by-step explanation:
Answer: 96°
Step-by-step explanation:
Sum of angles of a triangle = 180°
3 + 8 + 4 = 15
The biggest angle is 8/15 * 180 = 96°
Answer= 75 miles
Explanation: 120 divided by 8= 15
15 times 5= 75
Point A is exactly in the middle...it is halfway between 0 and 1...so it is 1/2 or 0.5
Answer:
115 degree
Step-by-step explanation:
x + 65 = 180 (Sum of angles in a straight line = 180 [Also known as Linear pair])
x = 180 - 65
x = 115 degree
