Answer:
Step-by-step explanation:
1/2(13-5)+(4+8)^2
A. 148
B. 144
C. 20
D. 16
We must follow "PEMDAS" order of operations rules. Anything inside parentheses must be done first, followed by exponentiation, multiplication and division, and finally additionl and subtraction.
1/2(13-5)+(4+8)^2 has three sets of parentheses enclosing mathematical expressions: (1/2), (13 - 5) and (4 + 8). These evaluate to:
1/2, 8, 12
and so we now have (1/2)(8) + (12)^2
Exponentiation is next. We get: (1/2)(8) + 144
Next is multiplication: 4 + 144
Last is addition: 148
Answer A is correct: 148
8 x 9+4^2-(63/7)
is evaluated in the same way:
8 x 9+4^2-(9), followed by exponentiation:
8*9 + 16 - 9, followed by multiplication:
72 + 16 - 9 = 79 (Answer C)
Answer:
D =44°
Step-by-step explanation:
Angle ACB = 2 angle ADB
So, ADB = ACB/2
= 88°/2
= 44°
The rate of change is -50 based on the information given.
You would have to substitute the amount of months into the equation for x to properly determine the average rate of change, which is not posted in this question.
