Answer:
- as written, -57
- as perhaps intended, C. -11
Step-by-step explanation:
The expression shown evaluates as ...
7 + 32(-5 +1)/2 = 7 +32(-4)/2 = 7 -128/2 = 7 -64 = -57
_____
If we assume your "32" is supposed to be 3², or 3^2, then the expression evaluates differently:
7 +3²(-5 +1)/2 = 7 + 9(-4)/2 = 7 -36/2 = 7 -18 = -11 . . . . matches choice C
_____
When in doubt, you can have the Google calculator evaluate your expression. However, you do have to write it properly and with all the required parentheses.
Answer: x * y = 1
Explanation: The only thing that changes between the examples are the first two numbers; the final answer is always 1. This would mean that the first number (x) multiplied by your second number (y) will always answer or equal 1.
Answer:
Answer: Option C is the best expression. Step-by-step explanation: We are asked to find 18.6 by 1.2.
Step-by-step explanation:
A.
8z+3 > 3z-17
subtract 3 from both sides
8z > 3z -20
subtract 3z from both sides
5z > -20
divide both sides by 5
z > -4
Answer:
C= 2 πr =18.85 m
Step-by-step explanation:
diameter= d= 6m
Radius = diameter/2= 6/2 = 3m
The circumference can be found by two formulas. One by using diameter and the other by using radius.
C= πd = 6* 3.14= 18.85 m
or
C= 2 πr = 2*3.14*3= 18.85 m
Using both the formulas gives the same answer.
The diameter is the line dividing the circle into half passing through the center.
The radius is half of the diameter or the lines which joins the center to the circumference of the circle.
